Abstract
Description
Technical Field
[0001] This invention relates to the field of financial management system technology, and in particular to an intelligent cost analysis and control service system. Background Technology
[0002] Existing financial management systems primarily focus on controlling employee expense reimbursements and managing the prices of raw materials and equipment. Their core objective is cost control, but they often neglect the issue of classifying and categorizing different costs and expenses. Taking R&D expenses as an example, by classifying and categorizing these expenses, companies can clearly understand their R&D investment, providing accurate data support for research project decisions, financial reporting, and tax filing. R&D expenses typically include equipment costs, material costs, personnel costs, travel expenses, intellectual property fees, and other related items.
[0003] Currently, methods for collecting R&D expenses mainly focus on reviewing the reasonableness of recorded and categorized R&D expenses, or identifying and collecting R&D expenses from the company's overall costs and expenses to reduce the workload of manual accounting. For example, Chinese patent CN117744788B discloses a method and system for collecting R&D expenses. This method generates structured data by collecting textual data of R&D expenses, constructs R&D knowledge graph instances, and filters eligible R&D expenses based on expense association rules. However, the above solutions are essentially ex-post screening methods based on expenses that have already been incurred, and cannot provide real-time control before or when R&D expenses are generated.
[0004] In practice, most companies face the problem of R&D personnel not linking expense claims to R&D projects. For example, travel expenses incurred by R&D personnel for R&D projects are difficult to accurately identify from a large volume of travel expenses if the reimbursement vouchers are not linked to the R&D project. Similarly, materials used in R&D are the same as those used in production, making it difficult to extract specific R&D material costs from the cost of goods sold. Therefore, it is necessary to classify R&D expenses at their source to ensure the accuracy of R&D expense allocation.
[0005] However, the existing expense reimbursement management methods still have the following technical shortcomings: First, the mandatory nature of project association is insufficient. In most companies' actual applications, the association between expense reports and R&D projects is often set as optional rather than mandatory. When R&D personnel fail to select the associated project due to negligence or inaccurate judgment of expense attributes, the finance department finds it difficult to automatically identify and correct such problems, resulting in R&D expenses being incorrectly classified as ordinary operating expenses or production costs. Second, there is a lack of an effective interception mechanism for expense reports of unassociated projects. Existing systems typically allow expense reports of unassociated projects to enter the approval process, and problems can only be discovered through manual review afterward, which is inefficient and prone to omissions. Summary of the Invention
[0006] In view of the shortcomings of existing technologies, the technical problem solved by this invention is to provide an intelligent cost analysis and control service system, which solves the problem that existing cost control systems lack correlation control over R&D expenses and thus incorrectly categorize them.
[0007] To address the aforementioned issues, the technical solution adopted by this invention is: an intelligent cost analysis and control service system, comprising a data management module, a research and development material control module, an expense reimbursement control module, and a budget early warning module; the data management module is used to store research and development project information and travel expense standard information; the research and development project information includes project name, cost budget, and research and development personnel information, and the travel expense standard information includes travel expense limits for job level and related job levels; The R&D material control module includes a material requisition management unit, a usage registration unit, and a material return management unit. The material requisition management unit is used to receive material requisition forms and perform R&D project association verification when the material requisition form is initiated by an R&D personnel. The usage registration unit is used to receive periodic registration information of actual usage. The material return management unit is used to receive material return information and automatically deduct the R&D expenses corresponding to the returned materials. The expense reimbursement control module includes a project association verification unit and a travel standard verification unit. The project association verification unit is used to perform R&D project association verification when the person claiming the expense is an R&D personnel. The travel standard verification unit is used to verify the travel expense reimbursement according to the travel expense standard information and return the reimbursement form that fails the verification. The budget early warning module is used to obtain R&D expense information generated by the R&D material management module and the expense reimbursement management module and deduct expenses from the budget in real time.
[0008] The beneficial effects of this solution are as follows: By setting up a research and development material management module and a reimbursement expense management module, this invention achieves end-to-end management of research and development expenses from their source to their collection. Compared with existing technologies, it has the following advantages: The system performs R&D project association verification at the source of expenses. When the initiator of a material requisition form or the person submitting the expense claim is an R&D personnel, the system automatically triggers R&D project association verification, returning any documents that are not associated with R&D projects. This prevents R&D expenses from being incorrectly classified as ordinary operating expenses or production costs due to unassociated projects, thus improving the accuracy of R&D expense classification.
[0009] A closed-loop management mechanism for material requisition, usage, and return has been established. By using a registration unit to receive periodic registration information on actual usage, and a material return management unit to automatically deduct the corresponding R&D expenses upon material return, this effectively solves the problem of inflated R&D expenses caused by discrepancies between requisitioned and actual usage in existing technologies, and ensures the authenticity of R&D expense data.
[0010] The budget early warning module enables dual-channel budget deduction for both R&D material control and expense reimbursement control. This allows project leaders and the finance department to monitor the budget execution of R&D projects in real time, promptly identify budget deviations, and take control measures, thereby improving the timeliness and effectiveness of R&D expense control.
[0011] Furthermore, the R&D project association verification of the material requisition management unit includes personnel verification, material verification, and association verification performed sequentially. The personnel verification is used to verify whether the person initiating the material requisition is an R&D personnel. The material verification is used to verify whether the requisitioned materials belong to any R&D project associated with that person when the personnel verification is R&D personnel. The association verification is used to return the material requisition form that is not associated with an R&D project when both the personnel verification and the material verification are positive.
[0012] Furthermore, the R&D project association verification includes personnel verification, expense type verification, and association verification performed sequentially; the personnel verification is used to verify whether the material requisition initiator belongs to the R&D personnel, the expense type verification is used to verify whether the reimbursed expenses belong to any expense type of any R&D project associated with the personnel when the personnel verification is R&D personnel; the association verification is used to return the material requisition form that is not associated with any R&D project when both the personnel verification and expense type verification are yes.
[0013] By setting up three levels of sequential verification—personnel verification, material verification (or expense type verification), and association verification—precise identification and control of R&D material requisition and expense reimbursement are achieved. Material verification or expense type verification determines whether the requisitioned materials or reimbursed expenses fall within the scope of the R&D projects associated with the R&D personnel. This prevents R&D personnel from mistakenly associating non-R&D expenses with R&D projects due to inaccurate assessment of expense attributes, or vice versa, thus improving the accuracy of expense aggregation. Association verification automatically returns documents not associated with R&D projects, achieving system-level interception of unassociated documents without relying on manual review to discover problems. This effectively solves the problem of inefficiency in existing technologies, which rely solely on post-event manual review to detect omissions.
[0014] Furthermore, it also includes a temporary storage module for temporarily storing document information; the association verification of the material requisition management unit is also used to send association confirmation information to the initiating personnel terminal when the personnel verification is yes and the material verification is no, and send the material requisition document to the temporary storage module; the association unit of the project association verification unit is also used to send association confirmation information to the initiating personnel terminal when the personnel verification is yes and the expense type verification is no, and send the expense report to the temporary storage module; the temporary storage module is used to temporarily store the material requisition document or expense report for a preset time period, and return the material requisition document or expense report if no confirmation information is received from the initiating personnel terminal within the preset time period.
[0015] By setting up a temporary storage module and a related confirmation mechanism, when personnel verification passes but material verification or expense type verification fails, the initiating personnel are given the opportunity to confirm the association, rather than directly returning the document. The temporary storage mechanism with a preset time period provides a buffer time for R&D personnel to confirm, while avoiding the impact of long-term document retention on financial processing efficiency. If no confirmation information is received within the preset time period, the system automatically returns the document, ensuring the closed-loop and standardized nature of the process. This achieves an organic combination of automatic system control and manual confirmation, ensuring the accuracy of R&D expense collection while taking into account the complexity and diversity of actual business scenarios.
[0016] Furthermore, the travel expense standard information also includes special time period information and regional information. The regional information includes a first-price zone, a second-price zone, and a third-price zone with reimbursement thresholds ranging from low to high. The special time period information includes holidays. The reimbursement control module also includes a dynamic threshold adjustment unit. The dynamic threshold adjustment unit is used to identify holidays based on preset special time period information and dynamically adjust the travel expense reimbursement threshold.
[0017] By setting a dynamic threshold adjustment unit, the system calculates a dynamic adjustment coefficient based on the ratio of hotel prices during holidays to those during non-holiday periods, thus dynamically adjusting the travel expense reimbursement threshold. It can automatically adjust the reimbursement standard according to hotel price fluctuations during the business trip period. During holidays and peak tourist seasons when hotel prices rise, the system automatically increases the reimbursement threshold, preventing employees from bearing additional costs due to fixed standards failing to cover actual expenses, or from circumventing control by falsely reporting expenses. This achieves dynamic adaptation of travel expense control to actual market conditions.
[0018] Furthermore, the dynamic threshold adjustment unit also includes a price acquisition unit and a baseline storage unit. The baseline storage unit is used to store the historical baseline prices of each star-rated hotel in each price zone during non-holiday periods. The price acquisition unit is used to acquire the star-rated hotel price information of the sampled cities in each price zone. The dynamic threshold adjustment unit calculates a dynamic adjustment coefficient based on the ratio of the real-time price during holidays to the baseline price during non-holiday periods, and adjusts the travel expense reimbursement threshold based on the dynamic adjustment coefficient.
[0019] Furthermore, the formula for calculating the dynamic adjustment coefficient is as follows:
[0020] in, For the first Price Zone The dynamic adjustment coefficient for star rating. For the first Price Zone Average price of star-rated hotels during holiday periods For the first Price Zone The average price of a star-rated hotel during the baseline period outside of holidays. The number of cities sampled. The number of hotels sampled in each city. For the first Price Zone The city The first Prices of star-rated hotels during holidays The number of days in the baseline period. For the first Price Zone Star-rated hotels in the baseline period The average price per day.
[0021] The dynamic adjustment coefficient is calculated by comparing historical baseline prices with real-time prices. Compared to directly using real-time prices as the standard, this method eliminates the impact of differences in economic development levels across regions and cities on absolute prices, making the dynamic adjustment coefficient more comparable and stable. Furthermore, this coefficient reflects the price increase multiple rather than the absolute price, facilitating consistent application across different regions and hotel star ratings. Calculating the dynamic adjustment coefficient stratified by price zone and hotel star rating ensures that R&D personnel at different levels and in different business trip destinations receive reimbursement standards that match their actual needs, improving the precision and scientific level of travel expense management.
[0022] Furthermore, the budget early warning module includes three levels of early warning: reminder, warning, and freeze. When the project budget execution rate reaches the preset first threshold, a reminder notification is sent; when it reaches the preset second threshold, additional approval is required; and when it reaches the preset third threshold, new material requisitions and reimbursements for the project are frozen in advance.
[0023] A three-tiered early warning mechanism—reminder, warning, and freeze—is adopted to monitor and respond in real time to the budget execution of R&D projects. This enables real-time monitoring of the budget execution process. The budget early warning module obtains R&D expense information from the R&D material management module and the expense reimbursement management module to deduct expenses from the budget in real time. This allows project leaders and the finance department to keep track of budget balances and execution progress at any time, avoiding the situation in existing technologies where budget information is delayed and problems cannot be detected in a timely manner.
[0024] Furthermore, the cost budget includes a material cost budget, a testing and analysis cost budget, a travel cost budget, and a meeting cost budget, and the material cost budget includes the types of materials.
[0025] Furthermore, it also includes a report generation module, which is used to generate a report on the use of R&D expenses based on the obtained expense reports, material requisition forms, and expense budget information, according to R&D projects and expense types.
[0026] By setting up a report generation module, the system can generate reports on the use of R&D expenses based on information such as expense reports, material requisition forms, and expense budgets stored in the system, categorized by R&D project and expense type. This module automates the aggregation and analysis of R&D expense data, eliminating the need for manual data collection and statistics, thus improving the efficiency and accuracy of R&D expense report preparation. Corporate management and the finance department can intuitively understand the cost structure and budget execution status of each R&D project through these reports, providing timely and accurate data support for research project decision-making, financial reporting, and tax filing. Attached Figure Description
[0027] Figure 1 This is a schematic diagram of the system modules in this solution. Detailed Implementation
[0028] The following detailed description illustrates the specific implementation method: Example 1 is basically as shown in the appendix. Figure 1 The system described is an intelligent cost analysis and control service system, comprising a data management module, a research and development material control module, an expense reimbursement control module, and a budget early warning module. The data management module stores research and development project information and travel expense standard information. Research and development project information includes project name, budget, and research and development personnel information, as well as budgets for material costs, testing and analysis costs, travel expenses, and meeting expenses. The material cost budget includes material types and their corresponding prices. Travel expense standard information includes travel expense limits for job levels and related job levels. For example, the accommodation standard for ordinary employees' travel expenses is three-star, for middle-level employees it is four-star, and for senior employees it is five-star.
[0029] The R&D material control module includes a material requisition management unit, a usage registration unit, and a material return management unit. The material requisition management unit receives material requisition forms and performs R&D project association verification when the initiator of the material requisition form is an R&D personnel, and returns material requisition forms that fail the verification. The usage registration unit receives periodic registration information of actual usage, and the registration period for periodic registration information of actual usage is weekly, monthly, or quarterly. The material return management unit receives material return information and automatically reduces the R&D expenses corresponding to the returned materials.
[0030] Specifically, the R&D project association verification in the material requisition management unit includes sequential personnel verification, material verification, association verification, and budget verification. Personnel verification verifies whether the person initiating the material requisition is an R&D personnel. Material verification verifies whether the requisitioned materials belong to any R&D project associated with that person, provided the personnel verification confirms they are an R&D personnel. Association verification marks unassociated R&D projects as failing verification and returns the material requisition form if both personnel and material verifications are successful. Budget verification retrieves the remaining budget amount for the materials corresponding to the R&D project associated with the current material requisition form and determines whether the amount corresponding to the current requisition quantity exceeds the remaining budget amount. If it exceeds, the requisition is rejected, the material requisition form is returned, and a budget shortage warning is sent to the initiating personnel's terminal.
[0031] The expense reimbursement control module includes a project association verification unit and a travel standard verification unit. The project association verification unit performs R&D project association verification when the person requesting reimbursement is an R&D personnel, and returns reimbursement forms that fail verification. The travel standard verification unit verifies travel expense reimbursements based on travel expense standard information and returns reimbursement forms that fail verification. Specifically, the R&D project association verification includes sequential personnel verification, expense type verification, and association verification. Personnel verification checks whether the person initiating the material requisition is an R&D personnel. Expense type verification, when the personnel verification confirms they are an R&D personnel, checks whether the reimbursed expenses belong to any expense type of any R&D project associated with that person. Association verification, when both personnel and expense type verifications are successful, marks unassociated R&D projects as failing verification and returns the reimbursement form.
[0032] The travel expense standard information also includes special period information and regional information. Regional information includes three price zones (Level 1, Level 2, and Level 3) with reimbursement thresholds ranging from low to high, and cities nationwide are divided and stored within their respective price zones according to different standards. Special period information includes holidays, such as New Year's Day, Spring Festival, Qingming Festival, Labor Day, Dragon Boat Festival, Mid-Autumn Festival, and National Day. The reimbursement control module also includes a dynamic threshold adjustment unit; this unit identifies holidays based on preset special period information and dynamically adjusts the travel expense reimbursement thresholds.
[0033] The dynamic threshold adjustment unit also includes a price acquisition unit and a baseline storage unit. The baseline storage unit stores historical baseline prices for each star-rated hotel in each price zone during non-holiday periods. The price acquisition unit acquires star-rated hotel price information for sampled cities in each price zone, obtaining hotel price data from Ctrip, Meituan, and Dianping platforms via API interfaces. The dynamic threshold adjustment unit calculates a dynamic adjustment coefficient based on the ratio of real-time holiday prices to non-holiday baseline prices, and adjusts the travel expense reimbursement threshold according to the dynamic adjustment coefficient.
[0034] The baseline storage unit stores historical baseline prices, providing a stable reference point for dynamic adjustments; the price acquisition unit acquires market price information in real time, ensuring the timeliness and accuracy of dynamic adjustments. Together, these two components enable the system to continuously track market price changes, providing reliable data support for travel expense management.
[0035] The formula for calculating the dynamic adjustment coefficient is:
[0036] in, For the first Price Zone The dynamic adjustment coefficient for star rating. For the first Price Zone Average price of star-rated hotels during holiday periods For the first Price Zone The average price of a star-rated hotel during the baseline period outside of holidays. The number of cities sampled. The number of hotels sampled in each city. For the first Price Zone The city The first Prices of star-rated hotels during holidays The number of days in the baseline period. For the first Price Zone Star-rated hotels in the baseline period The average price per day.
[0037] The system calculates dynamic adjustment coefficients based on price zones and hotel star ratings, ensuring that R&D personnel at different levels and for different business trip destinations receive reimbursement standards that match their actual needs, thus improving the precision and scientific nature of travel expense management. The baseline storage unit stores historical baseline prices, providing a stable reference point for dynamic adjustments; the price acquisition unit acquires real-time market price information, ensuring the timeliness and accuracy of dynamic adjustments. Together, these components enable the system to continuously track market price changes, providing reliable data support for travel expense management.
[0038] The budget early warning module is used to obtain R&D expense information generated by the R&D material control module and the expense reimbursement control module and deduct expenses from the budget in real time. The budget early warning module includes three levels of early warning: reminder, warning, and freeze. When the project budget execution rate reaches the first threshold, a reminder notification is sent; when it reaches the second threshold, a notification requiring additional approval is sent; and when it reaches the third threshold, new material requisitions and reimbursements for the project are frozen. In this embodiment, the first, second, and third thresholds are 70%, 90%, and 100% of the budget, respectively.
[0039] The three-tiered early warning mechanism enables refined and differentiated budget control. When the project budget execution rate reaches the first threshold, a reminder notification is sent, allowing relevant personnel to promptly understand budget usage and rationally plan subsequent expenditures. When the second threshold is reached, additional approval is required, strengthening budget control by adding approval steps and preventing budget overruns. When the third threshold is reached, new material requisitions and reimbursements for the project are frozen, forcibly blocking over-budget expenditures at the system level. These three progressively higher thresholds establish a tiered response mechanism, moving from "reminder and attention" to "strengthened control" and finally to "forced blocking."
[0040] The similarities between Example 2 and Example 1 will not be repeated here. The difference is that Example 2 also includes a temporary storage module for temporarily storing material requisition forms. The association verification of the material requisition management unit is also used to send association confirmation information to the initiating personnel terminal when the personnel verification is yes and the material verification is no, and to send the material requisition form to the temporary storage module. The association unit of the project association verification unit is also used to send association confirmation information to the initiating personnel terminal when the personnel verification is yes and the expense type verification is no, and to send the expense report to the temporary storage module. The temporary storage module is used to temporarily store the material requisition form or expense report for a preset time period, and to return the material requisition form or expense report if no confirmation information is received from the initiating personnel terminal within the preset time period.
[0041] By setting up a temporary storage module and a confirmation mechanism, when personnel verification passes but material or expense type verification fails, the initiating personnel are given the opportunity to confirm the association, instead of directly returning the document. This improves the system's flexibility and user experience. In real-world business scenarios, R&D personnel may receive materials for new projects or reimburse new types of expenses. Such situations may not be configured in the system's preset association rules, such as unclear other expense portions in R&D expenses. Through the temporary storage module and the confirmation mechanism, R&D personnel can proactively confirm the association, avoiding disruptions to normal business processes due to incomplete system rules.
[0042] The similarities between Example 3 and Examples 1 and 2 will not be repeated here. The difference is that Example 3 also includes a report generation module. The report generation module is used to generate a report on the use of R&D expenses based on the obtained expense reports, material requisition forms, and expense budget information, according to the R&D project and expense type.
[0043] The R&D material management module also includes a difference monitoring unit, which calculates the difference between the amount requisitioned and the amount used, and triggers an alert when the difference exceeds a preset difference threshold. This enables effective tracking of the actual consumption of R&D materials. In existing technologies, the material requisition and actual use are independent of each other, lacking a monitoring mechanism for the difference between requisitioned and used amounts. This invention, through the difference monitoring unit, periodically calculates the difference between the two, allowing project leaders and the finance department to understand the actual consumption of materials in a timely manner, avoiding the problem of inflated R&D expenses caused by the full amount of requisitioned being included in R&D costs while the actual amount used is less.
[0044] The preset discrepancy threshold can be flexibly set according to factors such as material type and R&D project characteristics. It can be a percentage of the requisitioned quantity or an absolute quantity, allowing discrepancy monitoring to adapt to the management needs of different materials and projects, improving the accuracy and operability of control. For example, if the discrepancy threshold is a percentage and set to 50%, and 500g of material is requisitioned but only 200g is used, which is below 50%, when the difference between the requisitioned and used quantities exceeds the preset threshold, the following situations may exist: unreasonable material loss, requisitioned quantity exceeding actual needs, or material being used for other purposes. After the system triggers an alert, relevant personnel can promptly verify the cause and take corresponding control measures, effectively preventing risks such as material waste and misappropriation. The discrepancy monitoring unit and the material return management unit work together to form a complete material control closed loop. After the discrepancy monitoring detects an anomaly, relevant personnel can return unused materials to the warehouse through the material return process. The material return management unit automatically reduces the corresponding R&D expenses, ensuring the consistency between R&D expense data and actual material consumption.
[0045] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics in the solutions is not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
