A made-to-measure order is the only kind where the customer can hand you the defect and you still pay for it. Get the made-to-measure order process right and custom work is your best margin; get it wrong once on a 40-unit hotel job and it eats a quarter's profit, because there is no restocking a 1,847 mm wardrobe.
The made-to-measure order process is the sequence that converts a buyer's requirement into a manufacturable, signed-off dimension set with a named owner for every number. The last four words are the whole job. Most disputes are not about accuracy — they are about who was responsible for the number that turned out wrong.
Your Next Move Depends on Who Measured
Scenario A: The buyer sends dimensions and asks you to build to them
You are a converter, not a designer. The buyer owns the measurement risk — but only if your paperwork says so and only if you did not silently "correct" anything.
Do this: restate their numbers back as a dimensioned drawing, with the words "manufactured to buyer-supplied dimensions; buyer confirms fit at site". If you spot something that looks wrong, flag it in writing and let them decide. Fixing it quietly transfers the risk to you, and a helpful undocumented correction is the most expensive kind of help there is.
Scenario B: You survey on site
Now you own every number, so price the survey and treat it as billable engineering rather than a free sales visit.
Do this: survey after the substrate is final — after plaster, after screed, after tiling. A survey taken against a bare stud wall measures a building that no longer exists by the time you deliver. Record who surveyed, when, and against what reference, and re-survey if the site changes.
Scenario C: The buyer sends an opening size, not a product size
This is the single most expensive ambiguity in custom work, and it arrives disguised as a clear specification. "1,800 wide" can mean the alcove, the finished unit, or the carcase without doors.
Do this: never accept a bare number. Every dimension gets a qualifier — opening, finished product, or carcase — and the deduction between them is stated explicitly on the drawing. If you build 1,800 mm of product into a 1,800 mm opening, you have built something that cannot be installed.
Scenario D: The buyer changes a size after sign-off
Normal, and manageable, provided you decided in advance where the freeze point sits.
Do this: define the freeze as a production event, not a date — "changes accepted until panel cutting begins". Publish the change fee at quotation time, not when the change arrives. A fee announced after the fact reads as opportunism; the same fee published up front reads as process.
Scenario E: You sell made-to-measure to consumers, not just trade
Here there is a commercial upside worth knowing precisely. Under Directive 2011/83/EU, the 14-day right of withdrawal does not apply to the supply of goods made to the consumer's specifications or clearly personalised. The UK mirrors this in the Consumer Contracts Regulations 2013, regulation 28.
Do this, carefully: the exemption depends on the goods genuinely being made to the customer's specification — not on you calling them custom. Choosing a colour from four options in a drop-down is generally not enough; a unit cut to a dimension the customer supplied generally is. Document the specification the customer gave, keep the sign-off, and state the exemption plainly in your terms before the order, because it must be disclosed pre-contract to be relied on. The European Commission's guidance on the Directive is the document to read before you write those terms.
Decision Matrix
| Situation | Who owns the dimension | What must exist before cutting |
|---|---|---|
| Buyer-supplied sizes | Buyer | Restated dimensioned drawing, signed |
| Your site survey | You | Survey record + final-substrate confirmation |
| Opening size given | Ambiguous until qualified | Written deduction: opening → product |
| Architect's drawing supplied | Architect, via buyer | Drawing revision number recorded on your order |
| Sample approved, sizes scaled up | You, unless stated | Golden-sample reference + tolerance for the run |
| Change after freeze | Buyer | Change order with fee and new lead time |
The Six Things to Lock Before You Quote
- Which dimension governs — opening, finished product or carcase — and who measured it.
- Unit and precision. Millimetres, whole numbers. "6 ft 1 in" and "183 cm" are not the same length, and neither is a cutting instruction.
- Tolerance, and who absorbs it. A ±3 mm manufacturing tolerance against a zero-tolerance opening is a failure waiting for a delivery date.
- Orientation and handing where the product has any — doors, drawers, corner units, anything with a visible face.
- The sign-off artefact. A dimensioned drawing with a revision number, not a sentence in an email thread. Emails have no revision control and no single source of truth.
- The freeze point and the change fee, both published in the quotation.

Why the Drawing Beats the Table
A specification table can be read two ways by two people who both act in good faith. A dimensioned drawing of the actual product, with the governing dimension called out on the face it belongs to and the deduction shown between opening and product, cannot.
This is where custom work differs from catalogue work: in a catalogue you are describing something that already exists, so a photograph plus a table is enough. In made-to-measure you are describing something that does not exist yet, and the drawing is the contract. That makes it worth building properly — measured values locked onto the geometry, one drawing per order, revision-numbered — rather than assembled by dragging arrows across a photo of last year's job. It is also why an AI-generated visual is the wrong tool at this step: it produces a picture of a plausible cabinet, not a controlled record of the one you are contractually about to build. A furniture spec diagram is what the sign-off should look like.
For the standard-range side of the catalogue that sits alongside your custom work, how to make a wholesale line sheet covers the format buyers expect.
FAQ
What is the made-to-measure order process?
It is the sequence that turns a buyer's requirement into a signed-off, manufacturable dimension set: qualify each dimension as opening, product or carcase; establish who measured it; agree tolerance and who absorbs it; issue a revision-numbered dimensioned drawing; obtain sign-off; then freeze changes at a defined production event.
Who is responsible if a custom size is wrong?
Whoever supplied the measurement, provided your paperwork records that clearly. If you surveyed, you own it. If the buyer supplied dimensions, they own it — but only if you restated their numbers on a drawing they signed and did not silently adjust anything.
Can customers return made-to-measure goods?
In the EU, the 14-day withdrawal right does not apply to goods made to the consumer's specifications or clearly personalised, under Directive 2011/83/EU; the UK equivalent is regulation 28 of the Consumer Contracts Regulations 2013. The exemption only holds if the goods are genuinely bespoke and you disclosed it before the contract — a colour choice from a dropdown usually does not qualify.
Should I charge for a site survey?
Yes, and separately. A survey transfers measurement risk from the buyer to you, which is a real liability with a real cost. Pricing it as free sales support means you carry that liability for nothing.
How much does a wrong custom size actually cost?
More than the unit, because there is no resale and often no salvage: manufacture, freight both ways where applicable, remake, and the delivery slot you lost. Running the arithmetic on your own numbers with the return cost calculator usually settles the internal argument about whether a proper sign-off drawing is worth the extra twenty minutes per order.
