Hi Cathleen,
Since Etsy has changed the hold times for Direct Deposit to be the day after the purchase is made, you would be able to get the deposit within a couple of days, but I believe any other payments that need to be made would have to be thru Paypal invoices or maybe a phone call to run a credit card thru square or similar.
Direct Checkout does not have the option to invoice someone for additional payments.
I hope that helps!
