Freelance Invoice Generator
A payable invoice in under a minute: line items, discount and tax, with a late-fee mode for overdue bills and a VAT mode that adds tax or strips it back out.

What this tool does
Most freelance invoices are built in a word processor, which means the maths is done by hand and the tax line is guessed. This generator does the arithmetic: enter up to six line items with quantities and rates, a discount and a tax rate, and it produces a clean invoice with a subtotal, discount, tax and total — ready to print or save as a PDF from your browser.
Two extra modes live on the same page because they belong to the same job. The late-fee mode works out what an overdue invoice has accrued under a daily percentage or a flat fee. The VAT mode adds tax to a net amount or reverses it out of a gross amount, for invoices where the tax treatment has to be shown separately.

How it works
The invoice total is built in order: each line is quantity multiplied by rate, the lines are added into a subtotal, the discount percentage is taken off the subtotal, and then the tax percentage is applied to the discounted figure. That order matters — discount before tax is the usual treatment, and swapping the order changes the total.
The late-fee mode multiplies the overdue amount by the daily percentage and the number of days, or applies the flat fee once — whichever type you picked. The VAT mode either adds the percentage to a net amount, or divides a gross amount by one plus the rate to recover the net figure and the tax inside it.
Assumptions and limitations
An invoice is only as good as the terms behind it. This generator does arithmetic, not legal work.
- Discount is taken off the subtotal before tax is applied. If your jurisdiction taxes the pre-discount figure, the tax line will differ.
- Tax rates are entered by you and never hard-coded. Confirm the rate that applies to your country and your client before sending the invoice.
- A late fee is only chargeable if your contract or written terms state it. This tool computes the figure; it does not create the right to charge it.
- The generator stores nothing. Copy the text or print the page — closing the tab loses the invoice.
Worked example
Example (illustrative inputs, not a real invoice). A website redesign at 800 for one unit, plus two revision rounds at 50 each, no discount and no tax:
| Item | Figure |
|---|---|
| Website redesign — 1 × 800 | 800.00 |
| Extra revision round — 2 × 50 | 100.00 |
| Subtotal | 900.00 |
| Discount (0%) | 0.00 |
| Tax (0%) | 0.00 |
| Total due | 900.00 |
Frequently asked questions
How should I number my invoices?
Use one running sequence with no gaps — for example 2026-001, 2026-002 — and never reuse a number. A gap or a duplicate makes a tax record harder to defend and makes chasing a payment confusing for both sides.
Should tax be added before or after the discount?
This generator takes the discount off first and then applies tax to the discounted figure, which is the usual treatment. If your jurisdiction taxes the pre-discount figure, work the tax out separately and enter it as a line item instead.
What if a client pays late?
Use the late-fee mode to work out the accrual, then send a reminder stating the original total, the fee and the new total due. Only charge a fee your contract or terms actually state — a fee with no agreed basis is hard to collect.
Can I save the invoice as a PDF?
Yes. Generate the invoice, then use your browser’s print function and choose Save as PDF. Nothing is stored on this site, so save the file before you close the page.
Does this tool handle tax for every country?
No. Tax rules differ by country, by client location and by what you sell. The rate is always entered by you — confirm it against your tax authority or a qualified professional before relying on it.
