Cantus is client, calendar, money, and piano-care software built by a working piano technician. It runs your whole business — and it runs offline in the basements and church halls where the signal doesn't reach.
Every client, every piano, every visit — with a recall queue that knows who's overdue before they do.
Your whole week at a glance, with one-tap driving directions and automatic route optimization.
The file every piano deserves — condition logs, environment tracking, photos, and recordings, all in one place.
A real ledger, branded invoices with online payments, and a year-end tax summary your accountant will thank you for.
The kind of visibility into your own business most piano technicians never get — from revenue trends to which month is actually your busiest.
One private link per client — no login, no app download, no friction. They see their piano's service history, condition trends, photos, and any open invoice with a pay button. You look like the most organized technician they've ever worked with.
