Stage payment invoice template UK (2026): payment schedule stages, CIS and VAT
Stage payment invoice UK, short answer: a stage payment invoice bills a named contractual stage from an agreed payment schedule (for example “Stage 2 — first fix complete per payment schedule”) — not an open-ended % progress valuation and not a retention release. Who pays is set by the contract (main contractor or client). CIS may apply when a CIS contractor pays you for construction operations — soften with HMRC’s CIS overview and your accountant. A private householder paying for work on their own home is usually not CIS and is never treated as the CIS contractor for that home. If you are VAT-registered (threshold £90,000), show VAT correctly on taxable lines; if you are not registered, do not charge VAT.
Use this page when the PDF is a schedule-driven stage bill tied to named milestones in the quote or contract. It is not an open-ended progress / interim valuation, not a deposit taken before work starts, and not a retention release of money previously held back. Sister pages for variation, snagging, interim and milestone templates may still be planned — link only live URLs here. Figures below are illustrative only. Need the PDF now?

Who pays, CIS and VAT on a stage payment invoice
Start with who is paying the named stage and which schedule line the PDF covers. Stage billing is about contract milestones already agreed, not a CIS shortcut.
Who pays you | Typical stage job | CIS? | VAT if registered |
|---|---|---|---|
Private householder | Domestic payment schedule on their own home (e.g. Stage 2 first fix) | Usually no — never treat them as CIS contractor for own home | Often 20% on ordinary domestic works — soften Notice 708; do not invent 0% |
Main contractor / CIS contractor | Named stage against a construction payment schedule | May be in CIS base when ops are in scope — soften with HMRC / accountant | Normal VAT, or reverse charge only when eligible contractor tests met — never on a householder |
Developer / client QS | Stage certificate against contract schedule | Depends whether the payer is a CIS contractor for construction ops | Show net / VAT / gross if registered |
Progress / open valuation (not this page) | % complete without a named schedule stage | Same CIS tests — use progress sister | Same VAT rules |
CIS rates (0% / 20% / 30%) sit with the contractor when CIS applies — InvoiceAdept does not decide status and does not file CIS300. VAT threshold is £90,000. InvoiceAdept does not file VAT returns, MTD updates or Self Assessment.
Stage payment vs progress vs deposit vs retention
Use this page when the deal is a named contractual stage from a payment schedule. Sister pages stay for sister intents.
Billing shape | When it fits | Invoice cue |
|---|---|---|
Stage payment (this page) | Named stage in an agreed schedule is due (e.g. Stage 2 — first fix) | Stage number + schedule label + fixed or % sum from the schedule |
Open-ended % or valued progress on a larger job | Stage / % complete + cumulative to date if useful | |
Upfront sum before (or as) work starts | Deposit % or fixed sum; credit later on stage / final | |
Holdback previously deducted is now due | Retention % / amount, release trigger (PC / defects end) | |
Final account without stage label | Closing balance with no schedule stage left | Final account narrative — not this template |
If the PDF is only a booking deposit, use the deposit sister. If you are billing an open % valuation without a schedule name, use progress. If you are releasing holdback, use retention. Do not invent CIS on a householder stage bill.
What a UK stage payment invoice must include
Field | Always? | Stage notes |
|---|---|---|
Your name or business name | Yes | Match Self Assessment / Companies House |
Your address and contact | Yes | Email helps QS / AP queries |
Customer name and address | Yes | Ltd = registered name; add site address if different |
Unique sequential invoice number | Yes | e.g. INV-STG-2026-0002 |
Invoice date | Yes | Date of issue |
Tax point / supply date | If VAT-registered and different | Useful when stage completion date differs from issue date |
Description of stage | Yes | Site, stage number, schedule label, amount; “stage payment per schedule — not retention release” |
Contract / schedule / prior invoice refs | Strongly recommended | Link to the payment schedule and any prior stage numbers |
Payment terms | Yes | Due on receipt / 7 / 14 / 30 days (or contract stage cycle) |
VAT number, rates, VAT amount | If VAT-registered | Show net, VAT and gross |
CIS UTR / deduction narrative | When a CIS contractor pays you within scope | Omit on true householder PDFs |
Bank details | Strongly recommended | Sort code and account name matching the invoice |
Never reverse-charge a private householder. Never invent CIS on a domestic own-home bill.
Copy-paste stage payment example (illustrative)
Scenario: sole trader plumber invoices a main contractor for Stage 2 — first fix complete per the agreed payment schedule on a commercial fit-out. CIS registered at 20%. Not VAT-registered. Schedule Stage 2 = £4,500 net (illustrative).
Line | Qty | Unit | Net |
|---|---|---|---|
Stage 2 — first fix complete per payment schedule, Unit B, week ending 12 Sep 2026 | 1 | Stage | £4,500.00 |
Prior Stage 1 / deposit | Already billed — not re-billed here | ||
Gross subject to CIS (this stage) | £4,500.00 | ||
CIS deduction @ 20% | −£900.00 | ||
VAT | Not registered — net only | ||
Amount payable by contractor | £3,600.00 |
Narrate on the PDF: “Stage 2 payment per schedule at [site]. Not a retention release. CIS registered 20%. UTR on file.” Keep each stage separate so AP can match the schedule.
CIS, VAT and reverse charge cues
Topic | Practical rule |
|---|---|
Stage for a CIS contractor on construction ops | May be in CIS base — soften |
Householder own-home stage payment | Usually no CIS; never treat them as CIS contractor |
VAT threshold | £90,000 |
Domestic reverse charge | Never on a householder; contractor tests only |
Deemed contractor | £3 million construction-spend framing — not £1 million |
Deposit vs stage | Deposit is upfront; stage is a named schedule milestone after work starts |
InvoiceAdept | Does not file CIS300, VAT, MTD or Self Assessment |
Agreeing the payment schedule before you start
Confirm stage names, amounts or percentages, completion evidence, who certifies each stage, and whether CIS will apply before you start. Put the schedule in the quote / contract so each stage PDF can cite the same labels.
Shape | How to show it on the PDF |
|---|---|
Fixed sum per named stage | “Stage 2 — first fix = £X per schedule” |
% of contract per stage | “Stage 3 = 25% of £Y = £Z” |
Deposit then stages | Deposit sister first; this page for Stage 1+ |
Stages then retention | This page for stages; retention sister when releasing holdback |
Weak: “Stage payment as agreed £4,500.” Usable: “Stage 2 — first fix complete Unit B week ending 12 Sep 2026 per payment schedule = £4,500 net, CIS 20%, not VAT-registered, not a retention release.”
Payment terms and getting paid
Main-contractor stage bills often follow a certificate / AP cycle (14 or 30 days after the stage is certified). Householders often prefer 7 days or due on receipt once the stage evidence is clear. Put bank details on the PDF. Soften B2B late-payment interest with the contract and your accountant.
Common mistakes on stage payment invoices
Mistake | Fix |
|---|---|
Vague “stage as agreed” lump | Name the stage number, schedule label, site and amount |
Calling a deposit a stage invoice | Use deposit until work on Stage 1+ has started |
Billing an open % valuation as a “stage” | Use the progress sister when there is no named schedule stage |
Calling a retention release a stage bill | Use the retention sister for holdback release |
CIS narrative on a householder stage PDF | Remove CIS lines when the householder pays |
Charging VAT when not registered | Net only until registered |
Mixing stage with a new variation line | Keep schedule stages separate from extras / VO lines |
Reverse-charging a householder | Never — reverse charge is contractor-to-contractor when tests met |
Frequently asked questions
Is a stage payment invoice the same as a progress invoice?
Not quite. Progress / interim often means an open-ended % or valued progress bill. A stage payment invoice cites a named contractual stage from an agreed payment schedule.
Does CIS always apply to stage payments?
No. CIS may apply when a CIS contractor pays you for construction operations. Private householders on their own home are usually outside CIS — soften with HMRC / your accountant.
Can I put CIS deduction lines on a householder stage invoice?
Usually no. If a private householder pays the stage on their own home, leave CIS narrative off the PDF.
What VAT threshold should I use in 2026?
£90,000. Soften registration with your accountant.
How is this different from a deposit?
A deposit is usually upfront before (or as) work starts. A stage payment is a named schedule milestone once work is underway.
How is this different from retention?
Retention releases money previously held back. Stage payments bill work against the schedule; they are not holdback releases.
Do I charge VAT on stage payments if I am not VAT-registered?
No. Net only until you are registered.
