Invoicing No more invoicing
on a Sunday night.

FitnessPlanner lines up who is due, at the right price. You check it, send everything in one go, and see who still has to pay.

01 / 04 Packages

Set it up once, the right price every time.

You put what you sell into a package once: the price, the credits that come with it, and when it renews. From then on every invoice is right, even for members with a price of their own.

  • Every month, or when credits run low
  • A price agreed per member
  • How often they can book, too
  • A 10-session card or PT pack works too

02 / 04 To invoice

No month slips through.

To invoice shows who is due: every month not invoiced yet, and every pack that is nearly used up. You draft all the invoices in one go, check them, and send them together.

  • Draft and send in one go
  • The member, a company, or a parent pays
  • A couple or a family on one invoice
  • Extra sessions or a product on top

03 / 04 Payments

See at once who still has to pay.

Every invoice gets a payment link: your members pay by Bancontact or card, or from then on automatically by direct debit. When they pay online, the credits land on their balance by themselves. Members you trust get them straight away.

  • Every payment recognised by its reference
  • Bank transfer, cash, or card, in part too
  • Fix a mistake with a credit note

04 / 04 Peppol and your accountant

Your invoices over Peppol, without extra software.

Since 2026, an invoice to a Belgian company has to go over Peppol. FitnessPlanner sends it that way, and everyone else gets a PDF by email. If you use onFact, your invoices and payments land in it automatically. Otherwise your accountant gets everything for a month or quarter in one zip.

  • See whether your invoice arrived
  • Spot a wrong VAT number before you send
  • The export per month, quarter, or year
An invoice to a company in FitnessPlanner: still open, and delivered over Peppol. An invoice to a company in FitnessPlanner: still open, and delivered over Peppol.

More than an invoicing tool

From booking to invoice in one app.

No more retyping

Bookings, credits, and invoices share one member file. You enter a new member once.

No commission

Members pay you directly, online too: the money goes to your own Mollie account. We take no commission.

A coach can do it for you

Give a coach access to invoicing. They can't change their own invoices, and the settings stay yours.

Made for Belgium

Belgian VAT, the small business exemption too, and invoices in Dutch or French. You talk to the people who build the app.

In the demo we set up a package, invoice a member, and mark it paid, so you see the credits land.
