Send the invoices there. Learn the parts here.
Invoice Ninja is where a voice teacher bills students and a choir sends its invoices, and gets paid. Stackapella is where the singing happens between lessons and rehearsals.

In Stackapella: the practice
- Warm-ups you build in a minute and send by link. Each one opens in the student's own range.
- Short courses to set between lessons: Vibrato, Range and registers, Breath and stamina, and Perfect your pitch.
- Choir groups: share a song, give each singer a part, and see who has started it and who has recorded it.
- Part-by-part learning tracks of one song you're rehearsing, a public-domain piece or your own arrangement, made for your group free when you ask.
Learning on Stackapella is free. Choir groups are for singers 18 and over, and you never see a singer's recordings or contact details.

Selling concert tickets?
Event Schedule already works with Invoice Ninja: a ticket sale can be billed as an invoice or a payment link in your Invoice Ninja company, and marked paid when it's paid. It needs a priced ticket, on Event Schedule's Pro plan.

Coming: the connection
Not open yet. This is what it's being built to do, and this page will say so the day it opens.
For voice teachers and coaches
- Each sale in your booksOnce coaching opens on Stackapella, each lesson or review a singer buys from you is recorded: the singer as a client, and an invoice marked paid.
- Fees and refunds tooStackapella's fee is recorded as an expense and a refund as a refund, so your books match what you were paid.
- One email, not twoThe singer already gets a receipt, so invoice emails stay off unless you turn them on.
For choirs, schools and companies
- Plus paid by invoiceFor a group that pays against an invoice, by bank transfer: an invoice from Invoice Ninja, and Plus turns on once it's paid.
- Never billed twiceA lesson booked through Event Schedule and paid in Stackapella is recorded once, by Stackapella.
You'll connect with an Invoice Ninja API token, and the address of a selfhosted Invoice Ninja. Stackapella will check it at once and show which company it's connected to.
