border-shop.ch — Magento 2 with SAP as the system of record

Bitbrew built border-shop.ch on Magento 2 and connected the store to SAP. The important architectural decision is the responsibility assigned to each system: Magento provides the commerce layer, while SAP remains authoritative for inventory and order data.

That avoids a common integration failure. If both the shop and the ERP independently attempt to control the same stock or order state, inconsistencies appear precisely where customers and operations need reliable information. The architecture therefore needs an explicit source of truth.

Inventory has to move from the ERP reality into the storefront, while orders created through Magento need to return into the process in a way that preserves SAP’s leading role. Magento can then perform the work of an e-commerce platform without becoming an accidental second warehouse or order-management master.

This pattern matters particularly for established retailers. An existing ERP does not disappear simply because a new storefront is introduced. Bitbrew connects the two systems so the online store operates on the company’s authoritative operational data. In projects like this, the quality of the ERP boundary is just as important as catalogue, cart and checkout.
