How to send a professional invoice (free template + the faster way)

The pain: "am I even doing this right?"

You've finished the work and now you need to get paid. So you open a blank document and try to remember: what actually goes on an invoice? Do I need an invoice number? My VAT number — if I'm registered? The client's address? Some legal wording?

Most founders cobble together their first few invoices from a half-remembered example and a lot of hope. It usually works — but "usually" isn't the same as right. A missing invoice number makes your records a mess at year-end. A VAT invoice without the proper detail can cause your client's accountant to bounce it back. And an invoice that looks thrown-together quietly tells a customer it's fine to pay slowly.

Getting paid starts with sending something correct and professional. Let's nail what a UK invoice must show — then show you the faster way that handles all of it for you.

What a compliant UK invoice must show

Here's the plain-English checklist. Every invoice you send should carry these:

• The word "Invoice" clearly on the document, so there's no doubt what it is. (If you're hazy on why that matters, see invoice vs receipt — an invoice is a request for payment; a receipt is proof it was paid.)
• A unique invoice number that follows on from the last one. Sequential numbering is what keeps your records straight and is expected for tax.
• Your business name and address, and your contact details.
• The customer's name and address.
• The invoice date (and the date you supplied the goods or service, if different).
• A clear description of what you're charging for, with quantities and the price of each.
• The total amount due, and your payment terms — when it's due and how to pay (bank details or a payment link).

If you're VAT-registered, it becomes a VAT invoice and needs a bit more:

• Your VAT registration number.
• The VAT rate applied to each item and the VAT amount in pounds.
• The price excluding VAT (the net), and the total including VAT (the gross). (See what is VAT? if that split is fuzzy.)

Sole trader or limited company? A sole trader invoices under their own or trading name. A limited company must also show its registered company name and can include its company number. That's the main difference — the rest of the checklist is the same.

The free template

Copy this, fill in the brackets, and you've got a compliant invoice:

INVOICE

[Your business name]                    Invoice number: [0001]
[Your address]                          Invoice date: [DD/MM/YYYY]
[Email / phone]                         Due date: [DD/MM/YYYY]
[VAT number — if registered]

Bill to:
[Customer name]
[Customer address]

Description                 Qty     Unit price     Amount
[Work / item]               [1]     [£0.00]        [£0.00]
                                            Subtotal:  [£0.00]
                                            VAT @ 20%: [£0.00]
                                            Total due: [£0.00]

Payment terms: [e.g. within 14 days]
Pay to: [Bank name, sort code, account number / payment link]

That'll get the money in. But notice everything it asks you to do: pick the next number without repeating one, do the VAT maths, track the due date, and remember to chase if it's late. Multiply that by every invoice, every month, and the template starts to feel like a chore with sharp edges.

The faster way: invoicing in Ledgers

In Ledgers, you don't fill in a template — you fill in what you're charging for, and the compliant invoice builds itself.

Numbering, dates and your details are automatic. The next sequential invoice number is assigned for you (no duplicates, no gaps), your business and VAT details are already on file, and the dates and terms are set from your defaults. Every invoice is correct by construction.

VAT is handled correctly. Pick the rate and Ledgers does the net/VAT/gross split for you and shows it properly on the invoice — so it's a valid VAT invoice your customer's accountant won't bounce. No manual maths, no missing VAT number.

It looks professional and goes out in seconds. The invoice is clean, branded and consistent every time — which subtly tells customers you run a tight ship and expect to be paid on time. You send it straight from Ledgers.

It's connected to getting paid. The moment you send it, the invoice starts watching its own due date, automatic reminders are ready to chase it for you (see how to chase late-paying customers), and when payment lands your bank feed matches it and marks it paid. The invoice isn't a dead document — it's the start of an automated path to cash.

What you'd see and do

You click new invoice. The number, your details and your VAT number are already there. You type the customer, the work, the amount; pick the VAT rate if it applies. Ledgers shows you the finished, compliant invoice — net, VAT and total all correct — and you send it.

That's it. No blank template, no hunting for what's required, no VAT sums on the back of an envelope. And because it's connected, you don't think about it again: it chases itself if it's late and marks itself paid when the money arrives. The "am I doing this right?" worry disappears, because the invoice was right before you even pressed send.

Frequently asked questions

What must a UK invoice include?

The word "invoice," a unique sequential invoice number, your business name and address, the customer's name and address, the invoice date, a clear description with quantities and prices, the total due, and your payment terms. If you're VAT-registered, also your VAT number and the VAT rate, VAT amount, net and gross totals.

Do I need to be VAT-registered to send an invoice?

No. If you're not registered, you simply don't show VAT — you send a regular invoice with no VAT number or VAT line. Once you're registered, your invoices must become full VAT invoices with the extra detail.

Can a sole trader send an invoice?

Yes. A sole trader invoices under their own name or trading name and includes the same core details as anyone else. A limited company additionally shows its registered company name (and usually its company number).

What's the difference between an invoice and a receipt?

An invoice is a *request* for payment, sent before you're paid; a receipt is proof a payment was *made*, given after. You'll often send both for the same job. See the full explainer linked below.
