How to Enable Partial Payments on Sparkforge Invoices

By Sparkforge Support Team ·Last reviewed May 3, 2026

Turn on Partial Payments in Payments → Invoices → Settings, set a minimum percentage of the invoice total, and customers can pay any amount at or above that floor. Works for one-time invoices and for recurring invoices when autopay is off.

Sparkforge lets you accept partial payments on invoices instead of forcing customers to pay the full amount up front. You set a minimum percentage of the total, and the customer can pay any amount equal to or greater than that floor from the invoice page.

When partial payments apply

One-time invoices: partial payments work fully.
Recurring invoices with autopay off: partial payments work the same way as one-time invoices.
Recurring invoices with autopay on: the first invoice can take a partial payment, but every subsequent invoice will autodraft the full amount.

Prerequisite

Connect a payment gateway first — Stripe, Authorize.net, or NMI. Without a gateway, the toggle has nothing to charge against.

Enable partial payments

Go to Payments → Invoices → Invoices Settings.
Open Payment Settings.
Toggle Partial Payments on.
Enter the minimum percentage of the invoice total a customer must pay.
Click Save.

The minimum percentage applies to every invoice you send while the toggle is on. Customers see it as a floor on the payment field rather than a fixed amount.

Frequently Asked Questions

Can a customer pay less than the minimum percentage?

No. The percentage you set is the floor. The customer can pay that amount or more, but not less.

Do partial payments work on recurring invoices?

Yes, but only when autopay is disabled. With autopay on, the first invoice accepts a partial payment and every recurring invoice after that drafts the full amount.

Which payment gateways support partial payments?

Stripe, Authorize.net, and NMI. You need at least one of these connected before the Partial Payments toggle does anything.

Is the minimum a percentage or a fixed amount?

A percentage of the invoice total. If you set 25% on a $400 invoice, the customer must pay at least $100.

Can I set different minimums for different invoices?

No. The percentage is a global setting under Payments → Invoices → Settings and applies to every invoice while it is enabled.
