How do I collect One-time Payments using the 'Pay what you want' invoice?
Click on the 'New Invoice', select Single Product under product type and choose the 'Pay what you want' 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 'Pay what you want' invoice the amount will be entered by your client during checkout.
