In most companies the ERP or merchandise management system is the source of truth — and therefore the most demanding connection point. This category covers linking such systems to the online shop: available interfaces and export formats, mapping customer master data and individual terms, handing over orders and reporting back status and shipping information, dealing with number ranges, tax codes and payment terms. We look at the specifics of large standard systems as well as smaller solutions common in mid-sized businesses, and describe how to build test environments. The goal is integrations that run stably in daily business and stay traceable when something does not arrive. We additionally look at test operations: which records belong in an acceptance test and how a synchronisation run can be repeated safely.
Batches belong to the movement, serial numbers to the single unit: data model, EU traceability rules, GS1 application identifiers and the recall as the real test.
Feature axes, the variant matrix and article number logic: how colour, size and version in the ERP become a solid variant structure in the shop, with GS1 rules.
Separate base, stock, selling and purchase units, pull conversion factors from the ERP, and map stock, minimum quantities and unit prices correctly.
