Invoice
Bill a client
Write an invoice, quote, proforma or receipt in your browser and save it as PDF. 30 currencies, 12 document languages, EU reverse charge and VAT handled.
The paperwork with numbers in it, done in the browser
Five free tools for the forms a small business actually fills in every month. They add the hours, apply the tax, roll the balance forward — and print a document you would be happy to send. No account, no upload, no watermark.
Pick one
Timesheet
Count your hours
Enter start and end times for each day. It works out hours worked, splits regular from overtime, and turns the total into an amount you can invoice.
Expense report
Claim expenses back
List what you spent, add mileage at your own rate, and print a claim your finance team can approve. Totals by category, advances deducted.
Purchase order
Order from a supplier
Raise a numbered PO with delivery details and terms, so your supplier’s invoice has something to match against.
Payment schedule
Plan a repayment
Enter the amount, rate and term. Get every payment listed with interest, principal and remaining balance, plus the total interest you will pay.
Why these five, and not fifty
There is no shortage of downloadable templates for this kind of paperwork, including on the rest of this site. A template is the right answer when a form is just blanks to fill in — a set of meeting minutes, a non-disclosure agreement, a handover note. You download it, you type into it, you are done.
It stops being the right answer the moment the form contains arithmetic that changes. Nine to five thirty minus a forty-five minute break, over a month, with anything past eight hours a day at time and a half. A balance that has to roll forward across sixty payments. A tax line whose wording depends on which country your client is in. That is not a document you fill in — it is a calculation you would rather not check by hand.
So these five were picked on one test: does the arithmetic change often enough that a file is the wrong shape?
- Invoice
- A spreadsheet cannot print the reverse-charge wording your EU client needs, or format 1.250,00 EUR the way a German bookkeeper expects. This can.
- Timesheet
- This is the one that is genuinely painful in a spreadsheet: 09:00 to 17:30 minus a 45-minute break, across a month, with anything over eight hours a day paid at a different rate. Typing times is faster than writing formulas.
- Expense report
- The maths is trivial and the format is not. What gets a claim approved quickly is a clean per-category total, the mileage shown as distance times rate, and a line saying what advance was already paid.
- Purchase order
- A PO is the reference number that stops your own invoices from sitting unmatched in someone’s accounts payable queue. Issuing one takes a minute and saves a fortnight.
- Payment schedule
- A single monthly-payment figure hides the thing worth knowing: how much of each payment is interest, and how much of it you still owe. The table shows both, and prints on one page.
How they work
Nothing is uploaded
What you type goes into your browser’s memory and stays there. Open the network panel and watch: no request carries your data anywhere, because there is nowhere here for it to go.
The preview is the printout
There is no PDF library and no server-side rendering. The document on the right is the element your browser prints, styled for A4 and US Letter. Choose “Save as PDF” as the destination.
They remember
Your business details, rates and settings are kept locally, per tool. Next month it is New, change three fields, print. Export writes a JSON file you own.
Currency and language are separate
Bill a German client in euros with the document written in English, or a Japanese client in yen with the labels in Japanese. Thirty currencies, twelve document languages, formatted the way each locale expects.
The part the tools cannot do
Filling the form correctly is half of it. The other half is knowing what the form has to say — which is where the guides come in.
What an invoice must contain
The elements that make an invoice a valid business document almost everywhere, plus what actually keeps you waiting for the money.
EU reverse charge
When you charge 0% and write “reverse charge” instead of adding VAT, what must appear on the invoice, and the one number to verify first.
UK VAT invoices
The required fields for a VAT-registered business in the UK, when a simplified invoice is allowed, and how sales to the EU are treated now.
Invoicing US clients
Why there is no VAT line, which tax form they will ask you for, and how to stop intermediary banks eating the total.
Korea: 세금계산서 vs invoice
A commercial invoice and a Korean tax invoice are different documents issued through different systems. Mixing them up is the mistake to avoid.
Invoice numbering
A scheme that stays sequential, sorts correctly, survives a year boundary, and does not advertise how few invoices you have sent.
