Allow users to set a fixed number of payments on subscriptions

Summary

Allow admins to create a subscription-style payment option that automatically stops after a fixed number of payments, rather than continuing indefinitely.

Use Case

Some course providers offer customers the option to pay for a course in instalments, for example 2, 3, or 4 monthly payments. Currently, this is often managed manually: the customer pays an initial amount when booking, then the provider charges the balance payment(s) later manually.

This can create extra admin.

A fixed-payment subscription would allow providers to offer instalment plans where payments are collected automatically, reducing manual follow-up and helping customers spread the cost without needing an external “buy now, pay later” provider.

Proposed Functionality

When setting up a subscription payment option, allow the admin to enter a Number of Payments.

For example:

• 2 payments of £150

• 3 payments of £100

• 4 payments of £75

The subscription should automatically cancel or stop after the selected number of payments has been collected.

Requirements

• Admin can choose the number of payments/instalments.

• Payments are taken automatically at the subscription interval.

• Subscription automatically ends after the final payment.

• All instalments are the same amount.

• Existing ongoing subscriptions should remain the default.
