A POS that talks with
everything else.
SUMWARE rarely runs alone. EFT terminal, mobile payment provider, fiscal partner, ERP, online shop, loyalty program, accounting: every retailer has their own landscape. SUMWARE slots in, and the rest of your stack stays exactly where it is.
One size fits none.
Quite possibly the most adaptable
POS on the market.
We stand by every word. Hold us to it!
SUMWARE offers extension points before and after every system step (discount and return reasons, payment methods, customer capture, receipt printing and much more). These system hooks enrich the default behavior or override it completely, without ever touching the core.
Add a fully flexible cron job system plus open-source receipt layouts for receipt printers, A4 PDF receipts and reports. A framework for customer-specific backend and frontend extensions completes the picture. That makes SUMWARE a natural fit for complex environments where processes change fast.

System hooks everywhere
Discount and return reasons, payment methods, customer capture, receipt printing, fiscal signing: every system step exposes extension points before and after execution. Enrich the default behavior or override it completely, without touching the core.
-
Cron jobs & open-source receipts
A fully flexible cron job system for background tasks. Receipt printer layouts, A4 PDF receipts and reports build on open-source templates: you edit them, we keep shipping updates.
-
Backend & frontend framework
Customer-specific backend and frontend extensions run in a dedicated framework. Your IP stays cleanly separated from the core and remains upgrade-safe across every release.
Beyond that, plenty of standard integrations ship out of the box: See what is included ↓
We read what is already there.
Integrations rarely fail at the API. They fail on time, budget and one-off formats. SUMWARE ships the tools that get you across the finish line without a classic interface project.
- Message parsers & MCP server
Third-party tools? We are listening.
Configurable message parsers for emails, CSV exports and webhooks from third-party systems, plus a built-in MCP server that lets AI agents work with SUMWARE directly. Integration without a months-long interface project.
- Phased legacy replacement
Switch store by store, skip the big bang.
SUMWARE is built for replacing existing POS systems. We keep your current interfaces running, take over master and transaction data from the legacy system and roll out the switch store by store. Fallback strategies safeguard sales operations at every stage and keep project risk under control.
- Rental availability for booking portals
Inventory out. Double bookings gone.
For rental assortments (skis, snowboards, equipment), SUMWARE reports the projected available stock for every future date to booking portals in real time. Per item, per size, per store. What is booked online is actually waiting on pickup day: no double bookings, no disappointed customers at the counter.
- OpenAPI + MCP for AI copilots
OpenAPI for reading, MCP for doing.
SUMWARE is fully documented in an OpenAPI 3 spec and can be explored right in the browser via Swagger UI. On top of that, an MCP server puts the APIs in the hands of AI agents: they read interfaces, write mappings and run E2E tests themselves. What used to be a specialist project becomes a copilot project.
- Omnichannel & business integrations
CRM, online shop, ERP, accounting: all old friends.
SUMWARE is built omnichannel from the ground up. Customer data, inventory, receipts and journal entries flow through proven integrations straight into the systems where you already manage them.
- eInvoice: XRechnung & ZUGFeRD
XRechnung. ZUGFeRD. Already table stakes.
Electronic invoicing is becoming mandatory across the EU step by step. SUMWARE already generates XRechnung and ZUGFeRD from every receipt today. When the mandate kicks in, you will be the retailer who is already done.
