Can I create a custom link for payment where customer can pay whatever amount they want to?

Are you running a B2B or B2C company?

 I can share additional information about creating a link to receive customer payments, willharris1. 

You can send a link to your customers so your customers can pay you with PayPal, Venmo, credit card, or ACH bank transfer. You can set the amount in the invoice, but your customer cannot edit the amount.

One option is to search for third-party apps that can integrate with QBO and let you create a custom link for payment where customers can pay whatever amount they want. Just use relevant keywords in the Apps menu. 

Here's how:

1. Go to the Apps menu from the left menu. 
2. Select the Find Apps tab.
3. Enter the app name in the search bar or select the Browse category dropdown menu to check out different apps.
