How to pay you
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.
Plumb split
Matte black and grey sheets crossing over a bronze strip, with a white field held back at the left end — the darkest band in the trade group and the only one with a metallic strip running under the geometry. Zebra rows beneath keep a mixed list of fittings and hours readable, and the balance due is a rail: a tinted panel with a thick colour bar down its left side. Plain sans typography, so nothing competes with the band.
Emergency rate for nights and weekends — separate line?
Yes, with its own description and its own rate. Two lines at different rates are clearer than one line with an explanation, and each is rounded before it joins the subtotal.
Can I reuse this invoice next week and just change the numbers?
The page keeps your last document in this browser, so your business details, logo and payment block are still there. Change the client, the lines and the number, and print again.
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.
