How to allow customer to pay via invocie?

Can the payment be made by invoice (45 days payment)?

Hi mulyadi,

Thanks for reaching out to Jotform Support. You can create a payment form with Purchase Order which allows you to set up products or collect amounts with no payment vendor integration required. You can use this to collect payments offline through a check, wire transfer, or cash. Here's how to add a Purchase Order element:

1. In Form Builder, click the Add Form Element button on the left side of the page.
2. Go to the Payments tab.
3. Search for Purchase Order, and click or drag/drop it to add.

1. Set up your Purchase Order settings.
2. Click the Continue button.

If that’s not exactly what you’re looking for, can you explain a bit more so I can help you better? 

Give it a try, and let us know how it goes.
