What a professional invoice must include

  • Your business details — legal name, address, and contact. Registered businesses should include their tax/VAT/GST number.
  • A unique invoice number — sequential numbering (INV-001, INV-002…) keeps bookkeeping and audits painless.
  • Dates — issue date and an explicit due date ("Net 14" beats "due soon").
  • Itemized charges — description, quantity, unit price. Vague invoices get queried; queried invoices get paid late.
  • Tax — shown separately at the correct rate for your jurisdiction.
  • Payment instructions — how exactly to pay you. Every extra step a client must figure out delays payment.

Getting paid faster

Invoice immediately on delivery, keep terms short (Net 7–14 for small clients), offer at least two payment methods, and send a polite reminder the day after the due date. Studies of small-business billing consistently show invoices sent the same day as the work are paid weeks faster than end-of-month batches.

Payment terms and what they actually mean

TermMeansBest for
Due on receiptPay immediatelySmall jobs, new clients, one-off work
Net 7 / Net 14Due within 7 or 14 daysFreelance and small-business default
Net 30Due within 30 daysLarger companies who will insist on it anyway
50% deposit, balance on deliverySplit paymentAny project over a week's work
2/10 Net 302% discount if paid in 10 daysEncouraging early payment on bigger invoices

Write the actual date rather than the term where you can — "Payment due by 14 August 2026" leaves nothing to interpret, while "Net 14" quietly invites the question of whether the clock started at issue or delivery.

Why invoices get paid late

Most late payment isn't bad faith — it's friction. Every gap the client has to resolve adds days:

  • No purchase order or reference number when the client's system requires one. Ask up front whether they need one.
  • Sent to the wrong person. Your project contact is often not accounts payable. Ask who should receive invoices before you send the first one.
  • Vague line items. "Consulting — $3,000" invites scrutiny; "Brand identity design, 3 concepts and 2 revision rounds — $3,000" doesn't.
  • Missing payment instructions. Put the exact details on the invoice: e-transfer address, bank details, or a payment link.
  • Late invoicing. An invoice sent three weeks after delivery signals the money isn't urgent to you either.

A simple follow-up sequence

Send the invoice the day work is delivered. A short, friendly reminder the day after the due date clears most cases — people genuinely forget. Follow up a week later referencing the original date, and at 30 days past due, call rather than email. Keep every message polite and factual: the overwhelming majority of late payments are administrative, and you want the client back.

Frequently asked questions

Is this really free? Where's the catch?
Free, no watermark, no account. The site is ad-supported. Your invoice data never leaves your browser — refresh the page and it's gone, so print/save before closing.
How do I save the invoice as a PDF?
Click "Print / Save as PDF", then choose "Save as PDF" as the destination in your browser's print dialog. Only the invoice itself prints — the form and the rest of the page are automatically hidden.
Is an invoice from this tool legally valid?
An invoice is valid based on its content, not the software that made it. Include the elements listed above plus any jurisdiction-specific requirements (e.g., GST/HST number in Canada, VAT number in the EU) and it's as valid as one from expensive software.
Can I use a different currency?
Yes — change the currency symbol field to €, £, ₹ or anything else. For international clients, state the currency name (e.g., "All amounts in CAD") in the notes.
What invoice number should I start with?
Anything sequential and consistent. INV-001 is fine, though some prefer starting at 1000 so an early invoice doesn't advertise that the client is your first. Never reuse or skip numbers — gaps are exactly what an audit asks about. Year-prefixed formats like 2026-001 make filing easier.
Can I charge interest on overdue invoices?
Generally yes, if you stated it before the work began — in a contract, quote or your standard terms. A common rate is 1–2% per month. It must be agreed in advance, so add a line such as "Overdue accounts subject to 1.5% monthly interest" to your terms. In practice its value is deterrent rather than revenue.
Do I need to charge sales tax?
It depends on where you are and whether you're registered. Most places have a revenue threshold below which registration is optional — in Canada it's $30,000 over four quarters for GST/HST. Once registered you must charge, collect and remit it. Set the tax rate to 0 here if you're not registered, and check your local tax authority's current threshold.
