Scenario 1 - FMCG distributor using SmartBill for billing
CRMconnect runs OMS + WMS + EDI + e-Transport. At shipment marking, WMS generates AWB, transport note with e-Transport UIT and DESADV to the retailer. At the end, CRMconnect pushes the invoice via API into SmartBill (with lines, prices, contracted discounts). SmartBill sends it to SPV. The accountant opens SmartBill as usual - sees all invoices, nothing changed.
