Staged Payments for Contractors: A Complete Guide
Why 30-day invoicing is structurally broken for renovation work
Thirty-day invoicing was built for B2B trade credit. Two companies, both with healthy balance sheets, both with accounting departments. It was not built for a self-employed builder fronting £4,000 of materials on a £20,000 bathroom, hoping the homeowner pays a month after handover.
Three things make it break in renovation:
- You finance your client with your own money. Every day materials sit on site unpaid is a day the job is funded by your overdraft, your credit card, or your personal savings.
- The client has no incentive to pay early. The work is done. The keys are back. The pressure runs one way.
- Disputes compound. A snagging issue that could be resolved in a conversation becomes a reason to withhold the whole balance for another month.
The industry’s unofficial answer has been to chase harder. Invoice software with payment reminders. Late-payment clauses. Reluctant adjudication. All of it treating the symptom.
The fix is structural. Move the payment closer to the work.
How staged payments actually work
A staged payment structure breaks the job into defined pieces. Each piece has a price, a definition of done, and a release trigger. The client agrees all of it upfront. When a stage is done, the money moves. No chasing. No reminders. No invoice sitting in someone’s inbox for three weeks.
The mechanism is old. Commercial construction has used interim valuations for decades. What is new is that the same mechanism is now available to domestic contractors without a quantity surveyor, a JCT contract, or a finance department. A digital wallet holds the full project value from day one. The money only moves when the stage is done and agreed.
The four stages that fit 80% of renovation jobs
Almost every renovation up to £50,000 / €60,000 breaks into the same four stages. The percentages flex. The structure does not.
| Stage | What it covers | Typical % — small job | Typical % — mid job | Typical % — large job |
|---|---|---|---|---|
| 1. Deposit | Design lock-in, scheduling, materials procurement, site prep | 25% | 20% | 15% |
| 2. First fix | Strip-out, structural, first-fix mechanical and electrical, plastering | 30% | 30% | 30% |
| 3. Second fix | Second-fix electrical and plumbing, joinery, tiling, decoration | 30% | 30% | 30% |
| 4. Final | Snagging complete, client walkthrough signed off, handover | 15% | 20% | 25% |
A few rules keep this working:
- Every stage has a written definition of done. “First fix complete” is not a stage. “First-fix mechanical and electrical tested to spec, plastering complete to rooms 1 and 2, skim to rooms 3 and 4” is a stage.
- Every stage price matches the cost sitting inside it. Labour and materials for that phase plus your margin. If stage 2 needs £6,000 of materials, stage 1 needs to pay for them.
- The final stage is big enough to matter. A 5% final payment is not enough to get a client back to the walkthrough. A 15–25% final payment is.
How to present this to a client without friction
Most contractors who have never worked staged say clients will push back. In practice, it is the opposite. Homeowners come to the first meeting already worried about giving a large sum to a stranger. A staged structure reads to them as a safer option, not a demand.
The line that works, almost verbatim:
“The project runs in four stages. Each stage has a price and a definition of what it covers. Your money goes into a protected wallet at the start. When a stage is done and you are happy with it, that stage’s payment is released. Nothing moves until you agree. That way you always see where you are, and I always know the next stage is funded.”
Two things do the work in that script. “Protected wallet” addresses the money fear. “When you are happy with it” hands the client the control they already wanted.
What the numbers look like over a year
Take a builder running £200,000 of annual revenue across ten jobs at £20,000 average. Under 30-day invoicing with a 20% deposit at start and 80% at handover, a typical £20,000 job looks like this on cash:
- Week 0: +£4,000 deposit, –£3,000 materials = £1,000 in hand
- Week 4: –£2,500 materials ordered for second fix = –£1,500
- Week 6: handover, invoice raised = –£1,500 still out
- Week 10: invoice paid, +£16,000 = £14,500 net
Four weeks at negative cash on every job. Across ten jobs a year, that is eight to twelve weeks where the business is funding clients.
Same job, same revenue, staged:
- Week 0: +£4,000 deposit (stage 1: 20%) = £1,000 in hand after materials
- Week 2: +£6,000 stage 2 release on first-fix completion
- Week 4: +£6,000 stage 3 release on second-fix completion
- Week 6: +£4,000 stage 4 release on handover
Same revenue. Zero weeks of negative cash. The business funds itself.
Where factoring and invoice finance still have a role
This is not a piece against factoring. Factoring exists because there is demand for it. The honest read is this: factoring is the right answer when you must use it, not when you choose to use it.
Factoring makes sense when:
- You are running large B2B invoices with long commercial terms that cannot be renegotiated.
- Your client is a developer, housing association, or general contractor who pays on their own cycle and will not agree to stages.
Factoring does not make sense when:
- The job is domestic and the client would agree to stages if asked.
- The job is small enough that the factoring fee meaningfully eats margin.
- You are using it to cover a structural cash-flow problem a better payment structure would fix.
If three of those are yes, restructuring the payment beats financing it every time.
30-day invoicing vs staged payments
| 30-day invoicing | Staged payments on Renno | |
|---|---|---|
| When you get paid | 30 days after handover | Instantly on stage completion |
| Dispute risk | High — full balance held | Low — only the stage in question |
| Chasing time | 3–6 hours per month | Zero |
| Client view of payment | Invoice arrives, debates start | Stage agreed upfront, no surprise |
| Working capital needed | 4–6 weeks of job cost | None |
| Fit for renovation work | Built for B2B trade credit | Built for jobs where stages exist |
Frequently asked questions
Will clients actually agree to staged payments?
In our experience with contractors on Renno, yes — more readily than they agree to a 30% deposit upfront with nothing else defined. Clients agree to staged payments because the structure gives them visibility. They can see what each stage covers and what has to happen for the next payment to release. That is the reverse of a deposit with no release mechanism.
What if a client refuses any deposit at all?
Then they are not a client yet. A homeowner who will not pay a deposit is telling you they do not trust the job will happen, which means they do not trust you, which means you have a sales problem upstream of the deposit. If the deposit is on a protected wallet with a clear release trigger, that conversation resolves in under a minute.
Can I still offer a discount for upfront payment?
You can, but the maths rarely works in your favour. A 2–3% upfront discount buys you no protection — the client has paid, the pressure is on you, and any snag becomes your problem alone. A 5% discount gets close to what you would save in admin and financing, but gives up meaningful margin. Staged payments give you most of the cash-flow benefit without the margin cost.
What about VAT on staged payments?
In the UK, a VAT invoice is raised at each stage against the stage amount. In NL, btw wordt afgedragen per termijn op basis van de factuur die bij de fase hoort. Either way, the tax point is the stage, not the start or the end.
What if the client disputes a stage?
The stage payment stays held. The other stages are not affected. This is the main reason to stage rather than invoice: a dispute on one £4,000 stage is a £4,000 conversation, not a £16,000 one. Resolution is faster, because the thing being disputed is defined and small.
How is this different from just sending invoices every week?
Weekly invoices still rely on the client paying, from their own bank account, on their own cycle. Staged payments with a digital wallet mean the client has already paid. The money is in the wallet. The release trigger is the only thing between the stage being done and the money landing in your account.
Do staged payments work on jobs under £5,000?
Two stages usually works better than four on a small job. A 40% deposit for design lock-in and materials, 60% on completion. The logic is the same: money is held, not invoiced, and the release is triggered by a defined outcome.
