Lessons taught and money in, matched at a glance.

QDD keeps your schedule, your lesson history and your payments in one place. Check off the lessons a payment covers, and when a parent asks about the month, the statement’s already sitting there.

Built for one-on-one piano teachers

Less time on the books. More time at the piano.

Scheduling, reschedules, make-ups, chasing payments. None of that is why you started teaching. QDD keeps the books so your morning check takes about ten seconds.

Never touches your money · Just a ledger · English or Chinese

No more handwritten statements

When a parent asks what they owe, send one PDF.

Choose the family and the months you want, and you get a PDF with every lesson and payment in order, including anything that moved. No more digging back through old texts to piece it together.

Nothing gets lost in a reschedule

You can’t cancel a paid lesson by accident, and prepaid credit moves with the lesson. When a parent asks, you have the record to show them.

Payments tied to lessons

Check off which lessons a payment covers and it’s logged. No more scrolling back through texts to work out where a family left off.

Statements in one click

Pick any date range and you get one clear PDF of their lessons and what they’ve paid.

What a day looks like

Check it once in the morning. That’s it.

How many lessons today, who still owes you, and one tap to mark them done. Switch to week or month whenever you want the bigger picture.

Schedule once, change it as often as you like

Set a student’s regular slot and the lessons fill in ahead of you. Reschedules, sick days and one-off swaps take a tap each, and the rest of the week stays put.

Summer’s the worst of it. Clear the whole stretch at once and pick up in September, instead of crossing out a page line by line. And if two students end up in the same slot, you’ll hear about it before they do.

Every payment matched to its lessons

When a payment comes in, check off the lessons it covers. Months later you can still see exactly what that money paid for, and QDD keeps a running total of what’s left.

Cash, check, Zelle, Venmo, PayPal, bank transfer. Record any of them. QDD just writes it down, and your money never goes near it.

You might be wondering

Three answers, up front

“Does it touch my money?”

No. QDD doesn’t collect payments, move money, or connect to a payment processor, and it never asks for your bank details. It just records what you’ve already been paid. A smarter version of the notebook you keep now.

“How long does it take to set up?”

Add a student, set their lesson time, and you’re running. Already keeping a spreadsheet? It imports directly, or send it over and we’ll do it for you. You’ll have the hang of it by your first logged lesson.

“Is my students’ information safe?”

Every teacher’s account is separate, so another teacher can’t see your students. You can add an unlock code on your phone too, which helps if you leave it sitting on the piano.

No limit on students, every feature included, and no credit card. It works the moment you sign up.

Rather talk it through first?

Tell us about your studio and we’ll walk you through it ourselves. That means getting your student list in, and squaring up the lessons that straddle the switch. A real reply from a person, not an autoresponder.
