Freelancing
Invoices and time tracking for freelancers.
About freelancing
Two tools for the administrative side of freelancing that nobody enjoys: producing invoices and tracking billable time.
The invoice generator covers the fields a professional invoice actually needs, and the omissions cause real problems. A unique invoice number is required for your own accounting and for most tax regimes, and duplicated numbers cause genuine trouble at year end. An explicit issue date and due date matter because 'due on receipt' is unenforceably vague โ 'payable within 14 days, by 15 August 2026' gives you something concrete to reference when chasing. Full contact details for both parties, a clear line-item breakdown, and the correct tax treatment complete it.
On tax: requirements differ by country and by your own registration status, and getting it wrong is expensive. Whether you must charge VAT or GST, at what rate, and whether a reverse-charge applies to a client in another country are questions with country-specific answers. The generator gives you the fields; what belongs in them depends on where you and your client are registered. Confirm it once with an accountant and reuse the answer.
For time tracking, the practical advice is to record as you work rather than reconstructing at the end of the week. Retrospective estimates are consistently wrong, and almost always in the direction of undercounting โ the ten minutes here and twenty minutes there vanish entirely, which is precisely the time freelancers most often fail to bill.
Frequently asked questions
What has to be on an invoice?
A unique invoice number, the issue date, a clear payment due date, full contact and address details for both you and the client, an itemised breakdown of work with rates, the total, any applicable tax with the rate stated separately, and your payment details. Requirements vary by country, so confirm the specifics for yours.
Do I need to charge VAT or GST?
It depends on your country, your registration status and where your client is based. Cross-border work often involves reverse-charge rules that shift the obligation to the client. This is worth confirming once with an accountant for your specific situation, then applying consistently.
What payment terms should I set?
Fourteen or thirty days from the invoice date is standard, stated as an explicit date rather than a phrase like 'on receipt'. A concrete date makes following up straightforward and removes any ambiguity about when payment became late.
Is my invoice and client data stored anywhere?
No. Invoices are generated in your browser and any saved entries stay in your browser's local storage on that device. Client details and rates are never transmitted to a server.
