Dynamic Call Billing Invoice Generation with Preliminary Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in dynamically tracking and applying varying tax rates and generating invoices for customers across different geographical territories, particularly in countries like Brazil and Mexico, where tax rates change frequently and must be accurately reflected on invoices for phone carrier services.
Innovation Solution
A method and apparatus that identify call sessions, retrieve account information, generate preliminary invoices, and update them with call details, including applicable tax rates, to automatically create and forward invoices to customers, ensuring accurate taxation and billing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dynamic tax rates are tracked and applied manually, then billing accuracy is improved, but system complexity and processing time increase
Solution Approach 1:
The system performs preliminary actions by retrieving account information and generating preliminary invoices before the call session ends. Tax rates are pre-applied to the preliminary invoice, and then the invoice is updated with final call details. This preliminary processing of billing information reduces the complexity of handling dynamic tax rates during the actual call billing process.
Solution Approach 2:
The billing process is segmented into distinct phases: call session initiation, account information retrieval, preliminary invoice generation, and final invoice update. This segmentation allows each phase to handle specific billing tasks independently, reducing overall system complexity while maintaining billing accuracy through structured processing steps.
2Measurement precision
If comprehensive invoice details are generated immediately, then billing accuracy is improved, but processing time increases
Solution Approach 1:
The system generates a preliminary invoice during the call session initiation phase, incorporating account information and estimated charges. This preliminary invoice is then updated with final call session details after the call ends. By performing billing calculations in advance, the system reduces processing time while maintaining accuracy through subsequent updates.
Solution Approach 2:
The invoice generation process is made dynamic by allowing the invoice to be updated after initial generation. The preliminary invoice serves as a template that is subsequently updated with actual call details, enabling the system to balance between immediate processing and final accuracy requirements.
3Device complexity
If manual invoice generation is used, then system complexity is reduced, but productivity and billing efficiency decrease
Solution Approach 1:
The system performs self-service by automatically retrieving account information, generating preliminary invoices, and updating invoices with call details without requiring manual intervention. This automation significantly improves billing efficiency while the structured approach keeps system complexity manageable through modular processing steps.
Solution Approach 2:
The billing system is designed with multi-functionality, handling account information retrieval, tax rate application, preliminary invoice generation, and final invoice updates within a single integrated system. This universal approach improves billing efficiency across different scenarios while managing complexity through unified processing logic.

AI summary
Call related invoices may be generated and applied to calls and related services especially in certain countries with dynamic tax models and specific entity authorization rules and other strict requirements for generating such invoices. One example method of operation may include identifying a call session being initiated by at least one call party device and retrieving account information of the at least one call party. Next, a preliminary invoice is generated based on the initiated call session including the account information, and the invoice is then updated to include details of the call session once the call session has ended.
