The invention discloses a management method and a system for warehouse materials. The management method for the warehouse materials comprises a warehouse entering sub-method. The warehouse entering sub-method comprises the steps of (1) warehouse warrant number scanning steps, wherein warehouse warrant numbers displayed on a display screen of a server are scanned and recorded, (2) cargo receiving steps, wherein bar codes of materials to be entered a warehouse are scanned, a first numerical value which presents the total number of the bar codes of the materials is stored with the warehouse warrant numbers in an associated mode, and the first numerical value is recorded, (3) cargo releasing steps, wherein warehouse position bar codes of corresponding warehouse positions are scanned, bar codes of materials to be entered the warehouse positions are scanned, and a second numerical value which presents the total number of the bar codes of corresponding materials of the warehouse positions is recorded, (4) warehouse entering end judgment steps, wherein the cargo receiving steps are circularly conducted, if the sum of the second numerical value is equal to the first numerical value, judgment is finished, and (5) warehouse entering submission steps, wherein a warehouse warrant is generated and submitted to the server. According to the management method and the system for the warehouse materials, through the adoption of the technical scheme, the technical problems that labor cost is high, working efficiency is low and accuracy rate is low in the prior art are solved, and the technical effects that warehouse materials can be managed accurately, timely, rapidly and efficiently are achieved.
