Annual billing is good for retention, but the upfront cost is a real barrier — plenty of clients would take the annual discount if they could spread the payment out, and abandon the checkout entirely if they can't.

Partial Payment splits an invoice into a scheduled series of smaller payments, so a client can commit to an annual plan while paying it down in installments that match their cash flow, without your team tracking a single schedule by hand.

The module handles the scheduling and reminders automatically, so the only change on your side is that some annual invoices now settle over a few payments instead of one — everything else about the plan, the discount and the renewal date stays the same.

For providers with a real drop-off at the annual-plan checkout step, this is usually a faster fix than trying to convince price-sensitive clients that the upfront number is worth it.
