What is a partial invoice?
A partial invoice bills part of an agreed total. Instead of one invoice on delivery, the project is billed in pieces as it progresses: a share on approval, a share when the shoot wraps, a share at picture lock, the balance on delivery. Each partial invoice references the full project, says which portion it covers and how much of the total has been billed so far, so that both sides can see where the money stands. It is the standard way long or expensive projects are billed, and the mechanism behind milestone billing and progress billing.
It is different from a deposit or prepayment, which is billed before work begins, and from a retainer invoice, which bills a recurring fee. A partial invoice is for work that has been done, in part.
Why it matters
Why a partial invoice matters
Productions spend money early and get paid late. A single invoice on delivery means the agency carries the cost of the crew, the locations and the post for the whole length of the project, and then waits thirty to sixty days for payment. Partial invoices match the money to the work: cash arrives as costs are incurred, and the agency does not finance the client's film. For the client, partial invoices spread the spend across months, align payments with visible progress, and give a natural checkpoint at each milestone to confirm the project is on track before the next payment is made.
They also keep disputes small. If something goes wrong at the shoot, it is a conversation about one milestone, not about the whole fee.
In practice
How a partial invoice works in practice
- 01
The billing plan in the proposal sets the milestones and the share of the total each one carries. When a milestone is reached, the producer confirms it with the client (the shoot wrapped, the cut was approved), and the partial invoice is raised the same day. It carries the project name, the purchase order number, the milestone it covers, the amount, the cumulative amount billed against the total, and the due date.
- 02
Each partial invoice is tracked to payment like any other. If the scope changes mid-project, the remaining milestones are revised in writing so that the partial invoices still add up to the new total. The final invoice closes the job and shows that the cumulative billing equals the agreed fee.
Watch out
What people get wrong about partial invoices
Billing by percentage of time elapsed rather than by milestone reached. A partial invoice for the halfway point in the calendar means nothing if the shoot has not happened; tie each one to something both sides can verify. The second mistake is losing track of the cumulative total, so the final invoice either double-bills or leaves money on the table. The third is forgetting that large clients need each partial invoice to match a purchase order line, and sending one that their system cannot place.
