ERP & merchandise management

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.
