Cash flow gaps

When the builder pays late and your suppliers do not wait

Waiting 30, 45 or 60 days on a builder's payment while wages and suppliers are due now? Here is how subbies bridge the gap and chase what they are owed.

Quick answer

A slow-paying builder turns finished work into a cash hole: you have paid for materials and labour, but the money arrives weeks later. Subbies bridge it by chasing payment claims properly, keeping a buffer, negotiating supplier terms, and using short-term funding that is sized to the outstanding invoices. The right option depends on how long the gap runs and how reliable the builder is.

Key points

  • Late payment is a timing problem first and a profit problem second, so fix the timing.
  • A clean payment claim is your strongest tool for getting paid sooner.
  • Short-term funding can cover the gap, but only borrow against money you are confident is coming.
  • Track which builders pay late and price that delay into future quotes.

Work done now, cash weeks later
Best first move
A correct, on-time payment claim
Funding range
$5k to $500k unsecured, sized on turnover

You finished the job on time, the builder was happy, and the invoice went out the same afternoon. Then nothing. Meanwhile your apprentice’s pay, the supplier statement and the ute repayment all arrive on schedule. That mismatch is the everyday reality of subcontracting, and it has very little to do with how good your work is.

Why does the builder pay late when the work is already done?

Most late payment is not malice. It is a chain. The client pays the builder when a stage is signed off, the builder pays the subbies from what lands, and every link in the chain tries to hold onto cash a little longer than the one below it.

You sit at the end of that chain. By the time the money reaches you, you have already carried the wages, fuel and materials for weeks.

A few patterns show up again and again:

  • The builder is waiting on a progress payment from the owner or a bank drawdown.
  • Your claim was missing a purchase order number, a variation approval or a site sign-off.
  • The accounts team only runs payments on a fixed day each month, and you missed the cut-off by a day.
  • The builder is stretched across too many jobs and is quietly using subbies as a free line of credit.

Knowing which one you are dealing with changes what you do next.

How do I get paid sooner without losing the work?

Start with the paperwork, because that is the part you control. A claim that is complete, correctly addressed and sent on the day the work finishes is hard to delay. A claim that bounces back for a missing detail restarts the clock.

Build a simple routine:

  1. Send the claim the day the stage is finished, not at the end of the week.
  2. Quote the job number, the stage, the agreed price and any approved variations.
  3. Keep a dated record of how it was sent and who received it.
  4. Diarise a check-in a few days before the due date.
  5. Phone first, then follow up in writing.

Each state has its own security-of-payment framework for building work, and the regulators publish plain-English guides. The Queensland Building and Construction Commission, NSW Fair Trading and the Victorian Small Business Commission are good starting points, and the Victorian Commission’s getting paid on time guidance is a sensible read even if you work elsewhere. Rules and timeframes differ between states, so confirm the ones that apply to your job.

What does the gap actually cost me?

It helps to put a number on it, because it tells you how much funding you might need, and for how long. This is an illustrative example only, with no real business or builder involved.

Item Illustrative amount
Job value, invoiced on completion $30,000
Materials already paid to suppliers $9,000
Wages and super already paid out $8,000
Cash tied up while waiting $17,000
Builder’s usual payment lag About six weeks

In that picture you are not short of profit. You are short of about $17,000 of working cash for roughly six weeks. That is a much smaller and more precise problem than “we need a loan”, and it points towards a short, sized solution rather than a long one.

You can model your own version in the cash flow gap planner.

Can I fund the gap while I wait?

You can, and plenty of subbies do. The aim is to borrow only against money you are confident is coming, for roughly as long as you expect to wait.

  • A short-term cash flow loan. A lump sum repaid over weeks or months, sized on your turnover and bank statements. Unsecured amounts typically run from $5k to $500k. See short-term loans for tradies.
  • Funding tied to the invoice. Money released against unpaid invoices from reliable debtors. We cover that in invoice finance for tradies.
  • A line of credit. A limit you draw on and repay as builders pay you, so you only use it when a gap appears.
  • A property-secured loan. If you own property, larger amounts from $20k to $5m become possible, which suits a bigger or longer gap.

How do I stop the same builder doing this again?

Treat late payment as a cost, not an accident.

Keep a plain list of the builders you work for and how long each one really takes to pay, as opposed to what their terms say. After a few jobs the pattern is obvious, and it should shape your quotes. A builder who reliably pays in six weeks is a different price from one who pays in two.

Then tighten the front end of every new job:

  • Agree payment terms in writing before you pick up a tool.
  • Ask for a deposit or an early claim on materials-heavy jobs.
  • Break big jobs into more stages so each claim is smaller and easier to approve.
  • Be willing to say no, or quote higher, when a builder has a poor record.

A quote that does not account for slow payment is quietly discounted. Our job quote margin calculator lets you see what a longer wait does to the real return on a job.

Ready to see what could bridge your gap?

If a builder is sitting on money you have already earned, you do not have to run the business on fumes while you wait. Putting your details in takes about a minute, and there is no credit check when you first enquire, so your file stays untouched just for looking at your options.

Your information goes to us, not out to a crowd of lenders, so your phone will not start ringing with strangers. A real person reads your situation and calls you to talk it through. The more accurately you fill in the form, including turnover and what is outstanding, the faster we can match you to the right option the first time.

How it works, step by step

  1. 1

    Day of completion

    Issue the claim or invoice the same day, with the job reference and the amounts clearly itemised.

  2. 2

    A week before the due date

    Send a polite reminder and confirm nothing is missing from the paperwork.

  3. 3

    Due date passes

    Phone the accounts contact, then follow up in writing so there is a record.

  4. 4

    Still unpaid

    Use your state's security-of-payment process, and line up short-term funding if wages cannot wait.

Frequently asked questions

Why do builders pay subcontractors so late?

Often it is their own cash flow. The builder may be waiting on the client or the bank to release a stage payment, then pays subbies from what comes in. Some also run long internal approval cycles. Whatever the reason, the cost of waiting lands on the subcontractor, who has already paid for labour and materials.

Can I charge interest or a late fee to a slow-paying builder?

Only if your contract or terms of trade allow it, so put payment terms in writing before you start. Some state security-of-payment laws also allow interest on unpaid claims. Check the rules for your state with the regulator, and keep your claims in the required form.

Should I stop work if a builder has not paid the last claim?

That is a decision to make carefully and usually with advice from your industry body or the regulator in your state, because the right to suspend work depends on the contract and the law. Many subbies instead tighten terms on the next job and get a deposit or earlier claims.

Can I borrow against an unpaid builder's invoice?

Yes, in a sense. Some options are tied to the invoice itself, and others are general cash flow loans sized on your turnover and bank statements. Either way, the lender wants to see that the work is done and the debtor is a genuine, established business.

Will a short-term loan make my cash flow worse later?

It can if the repayments land before the builder pays. Match the term to the realistic payment date, and leave a margin for the builder to be later again. A real person at the lender should talk through that timing with you before anything is signed.
