I also need to generate a generic link that people can use to pay. I have a client with several overdue invoices that wants to pay with one payment. Can I create a link so they can pay and manually link to the appropriate outstanding regular and finance charges invoices? (I'm using QB 2020 desktop.)

Please answer the question about a generic link, like what used to exist in the IPN platform. Do not provide information about creating and sending invoices to clients. That's not the solution to my question or to the original question posed above.

Ultimately, I'd like to include the generic link in the Statement Template so clients can click it and type in the amount they want to pay.
