Important For the figures you need your own professional AI — its cost comes on top of SBüro. What you need
A complete office with an AI team — for small businesses with 1 to 10 people
Your office does the work — you give the OK
SBüro is a complete office with an AI team: quotes, invoices with QR, reminders, deadlines and receipts — for trades, food businesses, services and new businesses. Nothing goes out without your OK.

- Invoice with Swiss QR payment part
- German, French, Italian, English
- Nothing goes out without your OK
- Phone, tablet and computer
How it works: three steps
Quotation → your OK → invoice with QR → your OK → payment reminder → your OK. Every document goes out only after your OK — every time.
1
Quotation
Enter items from your catalogue or freely. Totals, VAT and rounding are calculated by the program.
2
OK
Everything lands in the inbox first. You check, change or reject — nothing goes out without your OK.
3
Invoice with QR
The accepted quotation becomes the invoice with Swiss QR payment part. SBüro reminds you of payments in good time.

Invoices with QR payment part
available
Invoice to the Swiss standard with QR payment part (QR-IBAN or IBAN), also directly from the accepted quotation. Overview: open, due soon, overdue, paid.

available
Everything lands in the inbox first. You check, change or reject. Nothing goes out without your OK.
Deadlines & appointments

Sending directly from SBüro
available
After your OK, SBüro sends quotes, invoices and payment reminders by e-mail, with the PDF attached (invoices with QR payment part). The sender is your business name; replies go directly to your e-mail address.
Security & data
Honest and concrete: this is how SBüro handles your data.
Server in the EU (Netherlands) — data protection under the FADP (DSG)
The data is stored on a server in the EU, in the Netherlands. Data protection under the Swiss Federal Act on Data Protection (FADP/DSG).
Nothing without OK
No document or message leaves SBüro before you have approved it. The program checks this itself, not just the interface.
Data separated per business
Each business sees only its own data — separated in the database and checked with automated tests.
No advertising, no tracking cookies
This website sets no cookies. SBüro only uses the cookies needed for signing in.
For whom
For all small businesses and everyone who opens a business: trades and construction, restaurants and small food businesses, hairdressers and services, cleaning, consulting, shops and new businesses — for sole traders and businesses with several people.
With or without AI
Quotes, invoices, reminders and deadlines work without AI. For the characters you connect your own professional AI — it prepares drafts, you approve.
What you need in addition
For the figures you connect your own AI — in one of two ways. You pay the AI costs directly to the AI provider.
- Option 1: connection with your AI app (subscription) — You connect your professional AI subscription to SBüro via the open MCP standard. The figures prepare drafts, create deadlines and read the overview.
- Option 2: your own API key — You enter your own key (currently Anthropic; owner only, with second factor). The figures then prepare quotations, invoices and payment reminders as drafts; they read receipt photos with the Accounting module (M1).
The morning overview with figures and deadlines also works without AI. Every draft goes out only after your OK.
