With integrated e-commerce, part of the software solution is installed inside the ERP back-end system. This means that the connection between the business logic and database of a back-end system is configured automatically. Information that is available in the back-end system, for example article numbers, prices and current stock availability of products, is leveraged, without being copied to another system, and displayed in the front/back end of the e-commerce system. An integrated e-commerce software solution thus does not require investments in recreating and maintaining a separate database or business logic. Instead, it re-uses those of the back-end system, so all data are stored in one, single place. This can prevent input redundancy, errors and synchronization time.
