Native, not a browser tab
A real WinUI app for Windows 10 and 11, with a Mica surface, keyboard shortcuts, fast tables and touch for checkout and tablet. No sluggish web ERP that reloads on every click.
The whole ERP. Native on Windows.
ewws runs as a real Windows app, not a browser tab. Finance, CRM, payroll, inventory, calendar and the AI cockpit live in one fast, seamless interface. Swiss standards are built in, your data stays on your server, and from login to the paid QR-bill there is no break.
Why ewws on Windows
What a real Windows app does better
Most ERPs for Windows are a web portal in the browser or a collection of separate tools. ewws is a real Windows application where the whole business is connected: fast, seamless and on your own infrastructure.
One ERP, not a tool collection
Finance, CRM, payroll, inventory, projects and checkout share the same customers, items and accounts. What sales wins, accounting knows in the same second, without export and without double entry.
Data sovereignty, no forced cloud
Your data lives on your server in Switzerland or at your trustee, not in a foreign cloud. You decide where your figures live.
AI cockpit built in
Recommendations, dunning score and the AI value balance sit directly in the app and work on your real data. Everything stays traceable and is not an opaque cloud service.
Swiss standards built in
VAT per the FTA, payroll per Swissdec, QR-bill per SIX and GeBueV-compliant archiving are built in rather than bolted on. Multilingual in German, French, Italian and English.
Modules included
The modules are part of the edition instead of a per-user surcharge list. No per-seat tariff that grows with every new employee.
Modules
The whole business in one Windows app
Every module is native and connected to the same database. No switching between programs, no media break.
Cockpit and AI
The start screen shows revenue, receivables and open orders, plus "What the AI wants today" with recommendations and risk clusters. The day begins with what matters.
Finance and accounting
General ledger, accounts payable with PAIN.001 payment runs, CAMT bank reconciliation, VAT statement and closing. Every invoice is posted automatically.
CRM and pipeline
Leads, opportunities, campaigns and activities with a kanban pipeline and lead scoring, from the first enquiry to the loyal customer.
Payroll per Swissdec
Payroll runs, salary statements and ELM filings per Swissdec, plus AHV, ALV, BVG and withholding tax per canton, compliant and traceable.
Inventory and purchasing
Stock, goods receipt, stocktake, reorder signals and supply chains, with traceability and batches.
Calendar and team
Appointments, leave requests and team availability with a heatmap and approvals, connected directly to projects and service orders.
AI cockpit
The AI that thinks along, on your data
Every day ewws evaluates what happened in inventory, accounting, banking and dunning, and shows traceably where to act. All local on your figures, not in a foreign cloud.
Recommendations with reasoning
"What the AI wants today" lists concrete steps such as dunning clusters, OCR captures and posting proposals, each with evidence rather than a black box.
Dunning and lead score
Overdue receivables and hot leads are scored and prioritised, so you act first where it counts.
AI value balance and audit
The AI value balance shows maturity and review pressure per domain. You see where the AI leads and where a human should take a look.
Data sovereignty
Your figures, your server, your control
ewws is sovereign software. You run the server, you own the data, and every change is traceable.
Your own server
The ewws server runs on your premises, in a Swiss data centre or at your trustee. No provider sits between you and your data.
Audit-proof
Documents are archived GeBueV-compliant, every entry is traceable, and the audit log records who changed what.
No lock-in
Open formats and full data export across all business domains. Your data stays yours, even if you ever want to switch.
