Overview

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.

The context

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
What it does

Every department, one platform.

ProQoS spans 15 modules across the full operation, these are the ones teams use every day.

Orders & invoicing

Invoices, receipts, proformas, corrections and advance invoices in one flow, with a built-in print designer.

Warehouse management

Stock, locations, movements and stocktaking with PZ, WZ, PW, RW and MM documents kept accurate.

Backorders & supply center

Reconcile demand against incoming stock so nothing is oversold or sits idle.

Purchase orders

Purchasing with payment scheduling and auto-generation from real demand.

Complaints & returns

Customer and supplier complaints tracked end to end, tied to the original order.

Marketplace commander

Allegro, eMAG, Empik, Pigu, Morele and more, 11 marketplaces run from one panel.

Payments

8 payment providers wired in, including iMoje, Allegro Pay and InPost Pay, status flows onto the order.

Shipping

15 couriers with label printing, tracking and a calculator that optimizes packages, weight and COD.

Government compliance

KSeF e-invoicing, JPK, VIES, VAT-OSS, Intrastat, GTU, GPSR and EET handled in the platform.

CRM & helpdesk

Tasks, discount and exclusive codes, contracts with a calendar, reviews, banners and helpdesk.

Reports & analytics

30+ dashboards for sales, turnover, stock, debts, profitability, loyalty and staff efficiency.

Multi-store, multi-brand

Run 8+ retail brands and storefronts from a single database and one back office.
