Every client, every piano, every visit.
The records a piano business runs on: clients with all their pianos, a full service history, condition graphs for every instrument, and a recall list that knows who’s due before they do.

Everything about a client, one tap away.
Each client holds every piano they own, every visit, their invoices and contacts. Search finds anyone in a moment, by name, city, piano or notes, and status tells you at a glance who’s current, due soon or overdue.
- Multiple pianos per client, with make, model, serial, year and location
- Full visit history with services and prices
- Contacts for churches, schools and businesses
- Find and merge duplicate clients

The file every piano deserves.
Log pitch, humidity and temperature at each visit and Cantus draws the trend, with the healthy range shaded. It flags pianos worth watching, and keeps photos and recordings with the piano they belong to.
- Pitch drift, humidity and temperature graphs
- Environment alerts when readings leave the safe range
- Dampp-Chaser tracking
- Photos and audio recordings per piano
- Import tuning sessions from Pianoscope

Know who’s due before they do.
The recall action center puts overdue and due-soon clients, booking requests and environment alerts in one place. Call, text or email with a ready-written message, log it, and Cantus follows up for you.
- Due and overdue tracking from each client’s own service interval
- Ready-to-send call, text and email messages you can edit
- Automatic reminder emails with a button to book online
- Log a mailed postcard, and Cantus follows up with the client 30 days later if they haven’t booked

Every client gets their own page.
Send a private link, with no login and no app to download. Your client sees their piano’s history and condition graphs, the photos and recordings from your visits, any open invoice with a pay button, and a way to reach you.
- Service history, last visit and next due date
- Photos and audio recordings from your visits
- Humidity, temperature and tuning-stability graphs
- Open invoices with a pay button
- Call, text and email buttons, and a prompt to leave you a review
