Stage payments: structuring payment on bigger jobs

On a small job you turn up, do the work and get paid at the end. On a bigger one, that model puts all the risk on you: you're funding weeks of labour and a pile of materials before any money comes in, hoping the customer pays in full at the finish. Stage payments fix that. You tie payments to progress, so your cash flow matches the work and the customer pays for what they can see. Here is how to structure them sensibly and how to set them out on the quote so they're agreed before you start.

Why stage payments make sense on bigger jobs

A single payment at the end means you carry the whole job: materials, labour and your time, all out of your pocket until completion. If the customer drags their feet at the finish, or the relationship sours over something small, you're owed a large sum with little leverage. Stage payments spread that risk for both sides. You're never far out of pocket, and the customer never hands over a big lump for work they haven't seen yet. It's the fair, normal way to run a longer job, and serious customers expect it.

A deposit to book and order materials

The first payment is a deposit that secures the booking and covers your genuine up-front outlay, above all the materials you have to order before you start. Tie it to what it's actually for rather than plucking a percentage from the air. A deposit that covers the kitchen units you've had to order is easy to justify; one that's really just early profit is harder to defend if the customer queries it. State clearly what the deposit covers and that it secures their slot.

Milestone payments tied to completed stages

The heart of stage payments is linking each payment to a clear, completed stage of the work, not to a date on the calendar. The customer pays for progress they can stand in front of and see, which keeps everyone honest and your cash flow matched to the job. Pick milestones that are obvious and hard to argue about.

• Define each stage plainly, for example "on completion of first fix" or "once the structure is weathertight".
• Tie the payment to the stage being finished, not to a date, so it follows the actual work.
• Keep the stages visible and verifiable, something the customer can see is done.
• Size each payment to roughly match the work and materials in that stage, so neither side gets ahead of the other.

Retention: holding a little back

On bigger jobs it's common to hold back a small final portion, retention, for a short period after completion, to cover any snags that show up once the customer is living with the work. It reassures the customer that you'll come back to put right anything minor, and it's a normal part of how larger jobs are run. If you use it, state the amount, when it's released, and what it's for, so it doesn't come as a surprise. Equally, if you don't work that way, just make the final payment clearly the balance on completion.

The final payment on completion

The last payment is the balance, due on completion of the work (less any retention you've agreed). Be clear about what "completion" means, because that's where end-of-job disputes happen: the work in the scope finished to the agreed standard, snags addressed, and the site left clean. Tying the final payment to a clear definition of done, rather than a vague "when it's finished", protects both of you and gives the customer confidence about exactly what they're paying the balance for.

Put the whole schedule on the quote

A payment schedule you mention on the phone is a payment schedule you'll end up arguing about. Put it on the quote in writing: the deposit and what it covers, each milestone payment and the stage that triggers it, any retention, and the final balance. Agreed up front, it's just how the job is run; sprung mid-build, it looks like you're moving the goalposts. Setting it out clearly also makes you look like a proper business that's done this before, which earns trust on a job where the customer is committing serious money.
