ProQoS
An all-in-one ERP and e-commerce operations platform: manage orders, invoicing, warehouse, purchasing, complaints, CRM and analytics across 11 marketplaces, 15 couriers and 8 payment providers, all from one desktop panel. Multi-store, multi-brand and extensible to any market.

The whole operation, on one screen.
ProQoS is the system a company actually runs on. A sale becomes an order, an order becomes an invoice, stock is reserved, a courier is booked and the customer is notified, all inside one platform instead of a dozen disconnected tools and a pile of spreadsheets.
It sits behind the storefronts and the marketplaces as the sales and fulfilment engine, and in front of the team as the back office: warehouse, purchasing, complaints, CRM, government e-filing and reporting. An in-house Enterprise Service Bus keeps every integration running 24/7, and the whole platform runs 8+ retail brands from a single database.
Replace the patchwork with one backbone.
Growing commerce operations outgrow their tools. Orders arrive from 11 marketplaces, stock lives in one app, invoices in a third, couriers in browser tabs, tax filings in government portals and reconciliation in email. ProQoS was built to collapse that patchwork into a single, auditable flow from order to delivery to ledger.
- One record from order through invoice, stock and shipment
- 11 marketplaces commanded from a single panel
- Native payment and courier integrations, not manual exports
- Built-in government compliance: KSeF, JPK, VIES, VAT-OSS
- Multi-store and multi-brand from one shared database
Every department, one platform.
ProQoS spans 15 modules across the full operation, these are the ones teams use every day.
