Specify what triggers the two payment requests

Record the total agreed order amount, the deposit amount, and what makes the remainder due. The balance might be due on a stated date or a milestone the buyer can verify. Confirm how the selected invoicing system supports separate requests and how its reminders show an amount already paid.

Write the balance calculation into the order record

For a hypothetical $2,000 order with a verified $400 deposit, the starting balance is $1,600 before approved adjustments. If a line item changes, record the revised order total and retain the original deposit reference. Show the new balance and obtain any buyer approval your workflow requires before sending a revised request.

Test changes that can strand a payment

  • Record what happens if the deposit succeeds but the final request is canceled.
  • Define which team addresses an order cancellation or a partial shipment after a deposit.
  • Check what the buyer, order system, and processor each show after a change, refund, or final payment.
