How to Invoice for a Custom Handmade Order
A custom order invoice does two jobs: it bills the work, and it records the agreed specification so “not what I ordered” has a paper answer. Do it in two documents — a deposit invoice that carries the full spec, and a balance invoice at completion that references it — with the personalization written on the lines, not buried in a message thread.
Step 1 — Write the specification before the price
List what was actually agreed, in the buyer's own terms where possible: the item, size, materials, colors, the exact personalization text, and the agreed completion date. “Oak keepsake box, 20 × 15 cm, walnut finish — lid engraving: ‘For Rosa, on your first day’” is a specification. “Custom box” is a dispute waiting for a date. If the buyer approved a sketch or a photo, the notes can reference it (“per approved sketch shared Oct 28”) — the invoice then points at the approval, and the approval lives in your messages.
Step 2 — The deposit invoice
- One line for the full commission at the full agreed price — the whole job is visible from the start.
- The deposit as this document's own ask: either invoice only the deposit amount as its single line (“Deposit — custom keepsake box, per specification below”), or show the full price with the balance noted as due on completion. Pick one pattern and use it for every commission.
- The specification in the lines or the notes, complete — this is the document the deposit attaches to.
- Your terms for custom work, briefly: when the balance falls due (on completion, before dispatch is a common and fair pattern for personalized goods that cannot be resold).
Step 3 — The balance invoice
Mirror the deposit pattern: full price as the first line, the deposit as a visible negative line referencing the deposit invoice's number, and only the balance as the total. The buyer can verify the pair in seconds, and your two documents together tell the whole story of the commission — agreed, part-paid, completed, settled. Personalized goods carry a no-return reality in many consumer rules (goods made to a customer's specification are commonly treated differently — your jurisdiction's consumer law is the authority here), which is one more reason the specification belongs on the document, not in a chat thread that scrolls away.
Both documents take the same few minutes: open the maker, write the spec like you mean it, and download. For the delivery-shaped cousin of this job, see how to invoice for a local delivery order.
If the specification changes mid-make
Custom work evolves: the buyer upgrades the material, adds a second engraved line, moves the date. Handle the change on paper, not in goodwill. Agree the change and its price effect in a message, then let the *balance* invoice carry it as its own line — “Specification change agreed Nov 15: walnut upgraded to oak, +£18.00” — referencing the original specification rather than rewriting it. The deposit document stays as the record of the original agreement; the balance document records the agreement as it finished. Never quietly alter the first document: two versions of one invoice is the only paperwork outcome worse than none, because neither party can afterwards prove which specification was actually agreed when.
