# Is there a fixed amount on a fixed schedule?

[Charge a customer again](https://devportal.qa.winkpg.io/docs/decide/charge-a-customer-again.md): Whether repeat payments run on a contract the platform bills, on a schedule of your own, on an invoice, or at your checkout, and what the card networks need from each.

A schedule someone could write down in advance is a contract the platform can run. Anything else has to be triggered by your own system.

**Your answers so far**

- Is the customer there when each payment is taken? No. We charge them without asking each time.

**Choose one**

- [Yes. The same amount, every period.](https://devportal.qa.winkpg.io/docs/decide/charge-a-customer-again/put-the-customer-on-a-billing-contract.md): A monthly membership, or a known total split into equal payments.
- [No. The amount or the timing depends on what happens.](https://devportal.qa.winkpg.io/docs/decide/charge-a-customer-again/charge-the-stored-payment-method-when-you-need-to.md): Usage billed in arrears, a no-show fee, or a balance settled on delivery.
