Yes! Art Money can be used to purchase commissioned works. Your collector will need to pay you a minimum 10% deposit upfront, or the % required by you to commission the work (up to 50% is standard for commissions).
If the work is going to take more than 1 month to deliver, we recommend your collector wait until they receive the artwork before they create their Art Money purchase so they don't start their repayments until they receive the work.
