Nothing is switched on here, so nothing appears at the foot of the invoice.

Signature
- It calculates. Line totals are rounded before they are added, the way bookkeeping does it — so the figure on the invoice is the figure that lands in the bank, with no rounding drift between them.
- It knows tax can be inside the price, not only added to it. Templates written for one country get this wrong and quietly overcharge or undercharge everyone else.
- The discount comes off before the tax is worked out, because that is the order that is actually correct.
- The arithmetic is checked against a separate, independently written model before this page ships — and against a deliberate attempt to break it.
Canvas wave
Translucent chiffon waves running teal through magenta into orange, layered so the overlaps darken — the only band of the fifty that gets its colour from transparency rather than from flat fills. Under it, each line sits in its own rounded tinted block with a gap to the next, and the balance due is a square-cornered slab across the full width at 26px. Plain sans, because the band already carries every colour in the document.
Commissioned artwork with milestones — one invoice each?
One per milestone, each with its own number and date. That is what makes a half-finished commission auditable, and it is how a client’s accounts payable expects to see it.
Materials I bought for the piece — do they go on the invoice?
As their own line if you are recharging them. Keep them separate from the fee: a client reading one merged number cannot tell what was skill and what was canvas.
When one invoice becomes a hundred
This page makes a document. The bookkeeping spreadsheet keeps the year: what you invoiced, what was paid, what is overdue, and what it all means at tax time — with the same verified arithmetic.

Is anything I type sent to you?
No. The whole thing runs in your browser, including the logo. Your draft is kept in this browser's own storage so it survives a reload, and clearing it removes everything. We never see it and there is nothing to sign up for.
How do I get a PDF?
Press print and choose Save as PDF. Only the document prints — the editing panel disappears. Pick A4 or US Letter above so the margins are right for your country.
What is the difference between tax added to the prices and tax already in them?
If your prices exclude tax, the tax is added on top and the total goes up. If your prices already include it, the total does not change and the tax is separated out of it for the paperwork. Getting this backwards changes what your client owes, which is why it is a choice here rather than an assumption.
Can I issue a credit note?
Yes — put a negative quantity on the line you are reversing. The discount and the tax reverse with it, so a credit note and the invoice it cancels come to exactly zero together.
Why does the unit price allow four decimal places?
Because real prices have them: per litre, per kilometre, per unit. If a price is rounded to cents before being multiplied by a quantity, the line is wrong by more the larger the quantity gets.
