What every invoice needs
A clear invoice gets paid faster because the client never has to ask a follow-up question. Whatever your trade, a complete invoice includes:
- Who and to whom — your name or business and contact details, and the client's. If you are registered for tax, put your tax/VAT number here too.
- A unique invoice number — so both sides can refer to it. A simple running sequence works:
INV-001,INV-002. Never reuse a number. - Dates — the issue date and a due date. "Due on receipt" is fine, but a real date gets paid sooner than a vague one.
- Itemised work — a line per task or product with quantity and rate, so the total is never a surprise.
- Totals — subtotal, tax, any discount, and the amount due in bold.
- How to pay — bank details, PayPal, or a payment link, plus your terms. Put these in the notes field.
Payment terms, in plain words
The short codes on invoices just mean "how long the client has to pay":
- Due on receipt — pay now. Best for one-off jobs and new clients.
- Net 7 / Net 14 / Net 30 — pay within 7, 14, or 30 days of the invoice date. Net 30 is common with larger companies; shorter terms help your cash flow.
- 50% upfront — half before you start, half on delivery. Sensible for bigger projects.
Tax, and how to number invoices
Enter your local rate in the tax field and it is added on top of the subtotal — leave it at 0 if you don't charge tax. Whether you must charge it depends on your country and whether you are registered, so check your local rules. For numbering, pick one scheme and keep it consistent: a plain sequence, or a dated one like 2026-014. Consistent numbers make your own bookkeeping and any future audit far easier.
Getting paid on time
Send the invoice the day the work is done — the longer you wait, the longer the clock takes to start. If a payment goes past its due date, a short, friendly reminder that re-attaches the same PDF is usually all it takes. Because this generator keeps everything in your browser, you can reopen it, regenerate the identical invoice, and send it again in seconds.
Tools that pair with your invoices
Making the invoice is one step. People who bill clients usually reach for a few of these next:
- Merge PDF — combine several invoices or receipts into one file for a monthly statement or an expense claim.
- Split PDF — pull a single invoice page out of a longer scanned document.
- QR Code Generator — turn a payment link into a QR code your client can scan to pay.
- Image Compressor — shrink a large logo file so your invoice PDF stays small and email-friendly.
Frequently asked
Is my invoice data uploaded anywhere? No. Everything — your details, the client's, the amounts, your logo — stays in your browser and is used only to build the preview and the PDF. Nothing is sent to a server.
Does it add a watermark? No. The PDF is clean, with no Toolpia branding on it.
Can I use any currency? Yes — pick your currency from the list and every total is shown in it.
This tool helps you format an invoice; it is not tax or legal advice. Requirements for a valid invoice vary by country — check your local rules if you are registered for tax.
