When is a customer asked to pay?

You decide that per service. Go to Services, open the service and switch on Require payment at booking. Then you choose:
- Full price: the customer pays for the whole service in advance.
- Deposit: the customer pays a fixed amount in advance and the rest at the appointment. A deposit is available from the Groei plan.
If payment is required, the customer goes to a secure payment page from Stripe or Mollie after filling in their details.
What do I need to accept payments?

A linked account with Stripe or Mollie. You link it under Administration > Payments & accounting, on the Payments tab. Without a linked account you can't switch on payment at booking.
Read setting up payments, and if you're torn between the two, Stripe or Mollie: which should I pick?.
What happens when a payment fails?
Until the customer has paid, the appointment is on Awaiting payment and the time is held for them. You find these appointments under Appointments > Pending payment.
If nothing has been paid after 30 minutes, the time becomes free again by itself. The customer doesn't get a message about it. If they did pay some other way, open the appointment and choose Mark as paid.
When do I receive the money?
Stripe or Mollie transfers the money to your bank account, following the payout schedule of your account there. How quickly that goes, you see in your payment provider's dashboard.
Can I let customers pay later as well?
Yes. If Require payment at booking is off, the customer books without paying and you settle up at the appointment. Sending a payment request or payment link from Stippa isn't possible.
Does Stippa charge fees?
Stippa charges no transaction fees. Stripe and Mollie do have their own rates. You find those on their own websites.
Can I reverse a payment?
Yes, as an owner or admin. A refund never happens by itself, not even when a customer cancels in time. Read processing refunds.
