1. The manual workaround
Create a product called something like "50% deposit", let the customer buy that, then send the remaining amount as a Wix Invoice when the piece is ready.
What it costs you in money: nothing. In practice:
- The order is for a fake product, so inventory is not touched and your reports count a "deposit" instead of the thing you sold.
- Tax on the deposit product is set up by hand and can end up wrong for the real item.
- Every balance is a manual invoice you have to remember to send, then remember to chase.
Fine for two custom orders a month, not for ten.
