More than scheduling

From the first call to the paid invoice. In one app.

MosaOS connects communication, jobs, team and numbers. Information stays with the customer and the job – instead of scattered across mailboxes, spreadsheets and sticky notes.

01 — COMMUNICATION

Customer communication in context

Connect Gmail, Microsoft 365/Outlook and IMAP. Emails and call logs stay linked to the customer and the job – no callback gets lost.

02 — WORKFLOWS

One workflow instead of seven tools

A call, email or appointment becomes a job. From there, quote, invoice and payment status follow — without re-entering data.

03 — TEAM & NUMBERS

Your team knows what to do

Tasks, 15-minute appointments, assignments, mobile time tracking and job costing stay directly connected to the job.

Sound familiar?

The site runs smoothly — the paperwork doesn’t.

Materials on scraps of paper, hours from memory, quotes in the evening. In MosaOS the work report becomes the invoice.

“How many hours were we on the Müller site?” — notes in the van.
Materials forgotten on the invoice — the margin is gone.
Writing quotes at the kitchen table at night, because there’s no time during the day.
The customer complains, but nobody has photos of the condition beforehand.

Frequently asked

What businesses want to know before they start

What does MosaOS cost?

The base is CHF 49 per month and business — jobs, customers and team included. Further modules start at CHF 9, for example quotes, invoices or the email inbox. Cancellable monthly, no setup fee.

Can I try MosaOS first?

Yes. 14 days free, no credit card and no commitment. You set up your business and work with real data — if it does not fit, access simply expires.

Where is my data stored?

On servers in the European Union (Ireland). Processing follows Swiss data protection law and the GDPR. You can export your data at any time and delete your account yourself.

Can my team work from the field?

Yes. The team opens the field app in the phone browser — no installation. They see the day’s jobs with address and time, check in on site, add photos and close the job with a report.

Can I issue Swiss QR invoices?

Yes. The completed job becomes a PDF invoice with a Swiss QR code. You see the status at a glance: open, sent, paid.

How long does setup take?

Usually under 30 minutes. You pick your industry, add your team and first customers, and can start planning right away. Existing customer lists can be imported.

Bring calm to your business.
