Do you take payments through paperform? How?

First off, is there a more active community elsewhere? FB group? Reddit? Not finding a whole lot anywhere…

More importantly, if you take payments using paperform, how do you do it? Specifically, take a deposit now and collect the balance at a later, specified date, after services are rendered. It doesn’t seem to be a particularly unique use case but live chat says it can’t be done. Any workarounds? If I’m making two separate forms I may as well use standard invoices from something cheaper. It’s kind of a dealbreaker for me.

Use case: create a sales proposal where the client can select what optional add on features they would like. Once it’s set and signed, take 50% deposit now. In 30 days, once the work is complete, auto charge the balance. Too unique? No, right?
