# Installment Payments [![](https://downloads.intercomcdn.com/i/o/87389503/dd9a56226c2662ff1f99f0fb/Blank+Diagram.png)](https://downloads.intercomcdn.com/i/o/87389503/dd9a56226c2662ff1f99f0fb/Blank+Diagram.png) I'm very excited to release our new feature that allows you to take a fixed amount over time. Here's a quick example. You sell an item or service that is worth $1200. Customers aren't always able to afford this all at once so you create a plan that charges $100/mo. However, you need this to cancel after the 12th payment. Stripe unfortunately doesn't support this out of the box. This is where InstaPayments comes in. If you sign a customer up through one of our forms or through Stripe's Checkout, you have the option to set a total amount you want to charge. Once the subscription's invoices total to an amount greater than or equal to that value, InstaPayments will cancel that subscription. We store this amount on the subscription metadata.

If you have your own custom signup process, you simply need to set the metadata total\_installment\_in\_cents to the total amount you want to charge. Our servers will receive your Stripe web hooks and end the subscription if it meets the criteria. Have questions?
