In short: Here is how to invoice a client: send a clear document that shows who you are, who they are, what you did, how much they owe, when it’s due, and how to pay you. Give every invoice a unique number, set a payment term (14 or 30 days is typical), and send it the day the work is done. Below you’ll find exactly what to put on an invoice, when VAT applies, and how to get paid faster.
Your first invoice shouldn’t be the scary part of going freelance, but for a lot of people it is. What do you actually put on it? Do you charge VAT? What happens if the client pays late? This guide walks through it once, plainly, so you can send a professional invoice in a few minutes and get back to the work you’re actually paid for.
What is an invoice, exactly?
An invoice is a request for payment. It’s a dated, numbered document that tells your client what you delivered, what it costs, and how and when to pay. It’s also your record for tax time, so every invoice needs to be consistent, easy to find, and correct.
Two documents people often mix up:
- An invoice asks to be paid.
- A credit note cancels or reduces an invoice you already sent, for a refund, a discount after the fact, or a correction. (More on fixing mistakes below.)
What should a freelance invoice include?
Every professional invoice has the same core parts. Miss one and clients stall, or your accountant chases you later. Include:
- The word “Invoice” and a unique invoice number (for example
2026-001, then2026-002). Sequential, no gaps. - Your details: name or business name, address, and your VAT number if you’re VAT-registered.
- The client’s details: their business name and address.
- The invoice date and the due date (or payment terms, such as “Net 14”).
- A line for each thing you did: a short description, quantity, and price. Keep it specific. “Landing page design, 2 rounds” beats “design work”.
- The subtotal, any VAT, any discount, and the total due, in the currency you agreed.
- How to pay: your bank details (IBAN and BIC), or a pay-online link.
- A short note if useful, such as a thank-you or “Payment due within 14 days”.
A quick concrete example: a €500 logo project, invoiced on 6 August 2026, due in 14 days, payable by bank transfer or online. That’s a complete, professional invoice.

How to invoice a client, step by step
- Agree the details first. Price, currency, and payment terms should be settled before you start. The invoice just confirms them.
- Number it. Pick a simple scheme and never reuse a number. Consistent numbering keeps your books tidy (and your accountant happy).
- List the work clearly. One line per deliverable, described the way the client would recognise it.
- Add VAT if it applies (see the next section) and show the total plainly.
- Set the due date. 14 or 30 days is standard for freelancers. Shorter terms get you paid sooner, and there’s no rule that says 30.
- Send it the day the work is done. The single biggest lever on getting paid faster is invoicing promptly. An invoice sitting in your drafts is money sitting in someone else’s account.
- Save a copy and track it. You need to know what’s unpaid, what’s due soon, and what’s overdue, at a glance.
Doing this in a tool rather than a word processor means the numbering, totals, VAT, and PDF are handled for you, and you can see what’s outstanding without a spreadsheet. That’s what Tally Crow is built for: polished invoices and a clear view of who owes you what, with no accounting experience required.
Do freelancers need to charge VAT?
It depends on where you’re based, what you sell, and how much you earn. Most countries only require you to register for VAT once you pass a turnover threshold, and the rules differ across the EU. In plain terms:
- If you’re not VAT-registered, you don’t add VAT. Your invoice is just your fee.
- If you are registered, you add VAT at your country’s rate and show your VAT number.
- Cross-border EU B2B work often uses the reverse charge, where your business client accounts for the VAT instead of you.
If any of that is unclear for your situation, it’s worth sorting out once, properly, with your own accountant.
Good invoicing software lets you apply VAT (and more than one currency) without doing the maths by hand, so a compliant invoice looks the same whether your client is next door or in another country.
Tally Crow numbers, totals, and applies VAT to every invoice for you, then emails it as a polished PDF, from a free plan.
Start invoicing freeHow do I invoice a client in another currency?
Invoice in the currency you agreed with the client, state it clearly on the document, and keep a record of the amount in your own currency for your books. With Tally Crow you can raise invoices and credit notes in any currency: bank transfer works for any currency, while the pay-online option covers the currencies Stripe supports. Our guide on how to invoice a client in a different currency covers exchange rates, bank charges and a worked example. See pricing for what’s included on each plan.
What if I made a mistake on an invoice I already sent?
Don’t edit and resend the same invoice number. That leaves two different documents sharing one number, which is a mess at tax time. Instead, issue a credit note against the original (to cancel or reduce it), then send a corrected invoice with a new number. It’s the clean, auditable way to fix an error, and it’s how proper invoicing tools handle corrections.
How do I get clients to pay faster?
- Invoice immediately and set a clear, shorter due date.
- Make paying easy. Offer an online payment option so the client can pay in a click, rather than typing your IBAN into their banking app.
- Send a polite reminder as the due date approaches, and again if it passes. Automated due-soon reminders and one-click overdue nudges save you the awkward chase.
- Keep your details right. The wrong IBAN is a surprisingly common reason invoices go unpaid.
Send your next invoice in a few minutes
You don’t need accounting software you have to learn. You need to send a clear, correct invoice, know when it’s due, and get paid. Tally Crow does exactly that: professional PDF invoices, VAT and any-currency invoicing, online payments, and reminders, starting free (2 invoices a month, no credit card).
Frequently asked questions
Quick answers to common questions.
Your details and the client’s, a unique invoice number, the date and due date, a line for each thing you did, the subtotal, any VAT or discount, the total due, and how to pay. A short payment-terms note (such as “due within 14 days”) helps too.
Only if you’re VAT-registered, which usually depends on your country’s turnover threshold and what you sell. If you’re not registered, you don’t add VAT. Cross-border EU B2B work often uses the reverse charge. Check your country’s rules or ask an accountant.
Freelancers commonly use 14 or 30 day terms. Shorter terms get you paid sooner. Set whatever you agreed with the client, and send the invoice the day the work is done.
Yes. With Tally Crow you can invoice and issue credit notes in any currency. Bank transfer works for any currency, and the online pay-now option covers the currencies Stripe supports.
Issue a credit note against the original, then send a corrected invoice with a new number. Don’t reuse the old number or edit a sent invoice.
Use dedicated invoicing software rather than a word processor. It numbers invoices, totals them, applies VAT, produces a PDF, and shows you what’s unpaid. Tally Crow does this from a free plan.
