Systems we build

Order management & ERP integration

The order-management layer that finally connects your storefront, inventory, customers and back office — built on Open Mercato and wired into the ERP you already run, including Polish desktop systems like Subiekt GT that don't ship a clean API. One source of truth, no more re-keying between tools.
