Setting Progress Payments on a Longer Job

Long jobs are where small trade businesses quietly run out of money. You are four weeks into a six week job. Materials are paid for, wages have gone out twice, and nothing has been invoiced because the job is not finished. The work is profitable on paper and you are still short at the bank.

Work out where your money actually goes out

Before you can set sensible progress claims you need to know the shape of your own spending on that job. Most trade jobs are front-loaded: a large materials order early, then labour spread across the weeks, then a smaller fit-off spend near the end.

Sketch that out for the job in front of you. Where the big outgoings sit is where your claims need to sit. A payment schedule that puts most of the money at the end works for the customer and nobody else.

Tie each claim to something the customer can see

"Week three" is an invitation to argue. "On completion of rough-in" is not. Anchor every claim to a visible, checkable stage of the work, so when the invoice arrives the customer can walk out and see the thing you have described.

• A deposit on acceptance, to cover the first materials order
• A claim on completion of demolition or site preparation
• A claim at rough-in, frame-up or slab, depending on the trade
• A claim at lock-up or when the main install is complete
• A final claim on practical completion and handover

Four or five claims is usually enough. Ten small ones creates admin for both of you and makes the job feel like it is being nickel-and-dimed.

Put the schedule in the quote, not in a later conversation

The payment schedule belongs in the written quote the customer signs, alongside the scope. Set out each claim, what triggers it, the amount and the payment terms. If a customer is not comfortable with staged payments, you want to know that before you have ordered materials, not halfway through.

Check what your state requires as well. Residential building work in Australia has rules about deposits and progress payments that vary by state and by contract value, and they are worth knowing before you write your own schedule.

Invoice on the day the milestone is hit

This is the part that quietly costs the most. The milestone is reached on Tuesday, you mean to invoice that night, and it goes out the following Monday. That is five days of terms given away for nothing, on every claim, on every job.

Make the invoice part of the milestone rather than an evening task afterwards. Take the photo, mark the stage complete, send the invoice from the van. If someone else does your invoicing, they need to know the milestone is done the same day, not at the end of the week.

Handle a late claim straight away

A missed progress payment on a long job is a different problem from a late final invoice. You are still spending on that job, so the gap compounds every week you let it run.

Deal with it on the day it becomes overdue. A short, factual message, then a phone call. If the claim stays unpaid, suspending work is usually your strongest position, but only if the quote said you could and you tell the customer in writing before you do it. Walking off site without that groundwork can put you in the wrong.

Keep the final claim small

The last invoice is the hardest one to collect, because the work is done and the customer's leverage is at its peak. Anything outstanding, whether a mark on a wall, a missing handle or a bit of make-good, becomes a reason to hold the whole amount.

Structure the schedule so the final claim is a modest slice of the total rather than a quarter of it. Then the defects conversation is about a small sum and gets resolved quickly, instead of holding up money you needed weeks ago.

Bill variations as they happen

Variations left to the end turn into a single large surprise invoice and a dispute. Price the change, get it approved in writing, and add it to the next scheduled claim rather than saving it all up. The customer agreed to it at the time, so that is when it should appear on paper.

The short version

• Map your own outgoings on the job before setting claim points
• Tie each claim to a visible stage, not a date on a calendar
• Put the schedule in the signed quote
• Check your state's rules on deposits and progress payments
• Invoice the same day the milestone is reached
• Chase a late claim immediately, and give any suspension notice in writing
• Keep the final claim small and bill variations as they occur

Frequently Asked Questions

How many progress payments should a job have?

Enough that you are never funding the job out of your own pocket for long, and few enough that the admin stays manageable. For a job of a few weeks, four or five claims tied to clear stages usually works. The right number depends on how your costs fall, not on the length of the job alone.

Can I stop work if a progress claim is not paid?

Often yes, but it depends on what your contract says and on the rules that apply where you work. The safe approach is to include a clause covering non-payment in your quote, and to give written notice before you suspend work. Stopping without either leaves you exposed, so it is worth getting your standard terms looked at once rather than improvising on the job.

What if the customer wants to pay everything at the end?

Treat that as a signal rather than a preference to quietly accommodate. Explain that staged payments are how the materials and labour get funded as the job runs. If they will not agree and the job is long enough to strain you, it may be a job to decline. Carrying weeks of someone else's costs is a risk you are not being paid to take.
