About
About Invoice Generator
An invoice generator handles the formatting and math that a professional invoice needs, line items, subtotals, tax, a final total, so you're not rebuilding the same spreadsheet layout from scratch every time a job wraps up. This free invoice generator computes everything as you type and outputs a locked, polished PDF your client can't accidentally edit.
A proper invoice needs more than just a total figure. Standard practice includes your business name and contact details, the client's information, a unique invoice number, the issue date, an itemized breakdown of the work, the total due, and clear payment terms, a Net 15 or Net 30 due date, for instance. Sequential invoice numbering matters more than it seems, it's what makes your own bookkeeping and any future tax documentation actually auditable.
Doing this math by hand in a spreadsheet invites small errors, a subtotal that doesn't actually match its line items, a tax percentage applied to the wrong figure. The generator recalculates every total live as you add or edit a line item, so what you see in the preview is always accurate.
Enter your business details, your client's information, and itemize the work performed. Add your logo if you have one, set your payment terms, and once the live preview looks right, download it as a high-resolution PDF.
PDF specifically matters here because it locks the formatting, a client receiving a Word or Excel invoice could technically alter the listed price before sending it back, where a PDF effectively prevents that. Your billing data, client names, financial figures, stays local the entire time you're building it, nothing gets uploaded to generate the document.
FAQ
Frequently asked questions
What information does a professional invoice actually need?
At minimum: your business name and contact info, the client's details, a unique invoice number, the issue date, an itemized list of services, the total amount due, and clear payment terms or a due date.
Do I need an account to use this or save my invoices?
No, there's no account required. You fill in the fields and download the finished PDF directly. It's worth keeping copies of your downloaded invoices in your own records for tax purposes, since nothing is saved here on your behalf.
Will it calculate my sales tax for me automatically?
It calculates the math once you enter a tax rate, but you need to input the correct percentage yourself, since tax rates vary significantly by region and this tool has no way of knowing which jurisdiction applies to you.
Can I invoice in a currency other than US dollars?
Yes, there's a currency selector built in, so you can switch to euros, pounds, or another regional currency depending on where your client is based.
Is my client and billing data stored anywhere?
No, everything you type is processed locally in your browser as you build the invoice. None of it gets uploaded to or retained on a server.
Why should I send a PDF instead of a Word document or spreadsheet?
A PDF locks your formatting and numbers in place, where a Word or Excel file can be edited by the recipient, intentionally or not, before it's sent back or forwarded elsewhere.
