Welcome to the Communtipace, @iamcamilla-hotma.
Right now, creating one invoice can only have one due date. As a workaround, you can record an estimate first. After that, manually add the amounts to an invoice one at a time so the due date will be achieved.
To create an estimate, here's how:
- In the left menu, click the + New button.
- Select Estimate.
- Choose the customer's name, then fill in the necessary information.
- Add the total amount under the Amount column.
- Click on Save to record the transaction.
Once it's completed, convert it to an invoice:
- In the left menu, click the + New button.
- Select Invoice.
- Choose the customer's name under the Customer section.
- Look for the estimate at the right side of the page.
- Tap on Add, enter the amount on how much do you want to invoice on the pop-up window.
- Click Copy to invoice.
- Save the transaction.
- Repeat the steps for the rest of the amounts.
