How do I collect One-time Payments using the 'Decide at checkout' invoice?
Click on the 'New Invoice' and select the 'Decide at Checkout' option to create an invoice/donation form as shown in the below screenshot.
If you want to create a one-time payment invoice link then please go into the advanced option and select enable the 'Allow One-time' toggle as shown in the attached screenshot and it will allow your client to make only a single payment.
Using the 'Decide at checkout' invoice the amount will be entered by your client during checkout.
