What is a prepayment invoice?
A prepayment invoice asks for money ahead of the work. It is the deposit on a production, the first month of a retainer billed in advance, the advance on a long project that needs crew and locations booked before a frame is shot. It looks like any other invoice, with the project name, the purchase order number, the amount and the terms, but what it covers is a commitment rather than a delivery: it secures the dates, the people and the costs, and it is credited against the total when the later invoices are raised.
In accounting terms a prepayment is a liability until the work is done: the agency holds the client's money against future delivery and recognizes it as revenue as the work is earned, not when the cash arrives.
Why it matters
Why a prepayment invoice matters
Production is paid for in advance. A crew is booked and a location deposit is paid weeks before the shoot; equipment is reserved; travel is bought. Without a prepayment the agency carries all of that for the client, which is a loan nobody agreed to and the reason small studios run out of cash while they are busy. A deposit also changes the client's behavior: a project with money down gets decisions made, approvals signed and dates held. For the client, a prepayment invoice is clarity. It says what is needed to start, and it is the first checkpoint in a billing plan both sides have already agreed.
It matters most on the jobs where the hard costs are largest, which are also the jobs where a late payment hurts most.
In practice
How a prepayment invoice works in practice
- 01
The billing plan in the proposal sets the prepayment: a percentage of the total or a fixed amount, due on approval or on signature, and sized to cover the early hard costs. The client approves the proposal, raises a purchase order, and the agency issues the prepayment invoice immediately, quoting the PO number and stating what the payment secures and when the balance will be billed. Work, or at least the booking of costs, starts when it is paid.
- 02
Later invoices show the prepayment as already received, so the cumulative billing always adds up to the agreed total. If the project is canceled, the terms say what happens to the prepayment: typically the agency keeps what covers costs already committed and refunds the rest.
Watch out
What people get wrong about prepayment invoices
Being embarrassed to send one. Agencies that skip the deposit to seem easy to work with end up financing the production and chasing the whole fee at the end, which is harder on the relationship than a deposit ever was. The second mistake is sizing it as a gesture. A small deposit that does not cover the early costs leaves the agency exposed and tells the client the number was negotiable. The third is recognizing it as revenue on receipt, which makes the month it arrives look wonderful and the month the work is done look like a loss.
