A deposit in PortaPro is a real invoice: the customer pays it online from the quote link (or you record a check with Collect Payment), and once paid it is credited to their final invoice automatically.
On a quote
The customer sees Accept & pay deposit, signs, and goes straight to the deposit's payment page. The quote reads Approved · Deposit due until it is paid, and you get a Deposit received notification when it is. On the balance date PortaPro creates the full invoice with the deposit credited, and charges the card the customer saved on the deposit page, or emails the invoice.
Deposits apply to one-time quotes, including event rentals. Recurring quotes bill on the rate card cycle.
On a job
Open the job and choose Request Deposit: enter a percentage or a flat amount, then copy the payment link, Email it, or Collect now. The job wizard no longer has a deposit step.
