Tips for invoices that get paid on time
A clear invoice is easier to approve and harder to lose in someone’s inbox.
- Give every invoice its own numberUK invoices need a unique identification number. Number them in order, such as INV-0042, so you and your client can refer to a specific invoice when chasing or checking a payment.
- Put payment details in the notesUse the Notes box to say how to pay: account name, sort code and account number, and the invoice number to use as the payment reference, so each payment is easy to match.
- Make the due date clearWrite your terms, such as “Net 30” or “due on receipt”, in Payment terms and set the due date to match. It’s the date your client’s accounts team will look for.
- Keep a copy of every PDFNothing you type is saved between visits, so file each invoice PDF in a folder, named with its number and client. HMRC expects you to keep business records for several years.
Like every Altto tool, this runs on your device — nothing you add is uploaded. How Altto works
is when payment is due from a UK business customer if you haven’t agreed other terms. After that, the late payment rules let you claim interest.
What a finished invoice looks like

How the totals are worked out
- Subtotal is every line’s quantity × price added up: £1,270.00.
- Discount comes off the subtotal, as a percentage or a fixed amount: 10% of £1,270.00 is £127.00, leaving £1,143.00.
- Shipping is added next (there’s none in this example).
- Tax / VAT is worked out on the amount after the discount, plus any shipping: 20% of £1,143.00 is £228.60. Untick “Add tax / VAT to shipping” if your delivery charge shouldn’t be taxed.
- Amount paid, such as a deposit, comes off the total to give the balance due: £1,371.60 − £400.00 = £971.60.
What to put in each box
| Box | What to write |
|---|---|
| Invoice number | A unique number that follows on from your last one, such as INV-0042. Never reuse a number. |
| Invoice date and due date | The date you send it, and the date payment is due. Match the due date to your terms (30 days after the invoice date for “Net 30”). |
| Your details | Your name or business name, address and contact details. Add your VAT number here if you’re VAT-registered. |
| Bill to | Your customer’s business name and address. For a company, use its full registered name. |
| PO number | Only if your customer gave you a purchase order number. Many accounts teams won’t pay without it. |
| Line items | One line per job or product, specific enough to recognise later: “Logo design, 3 concepts” rather than “Design work”. Include the date of the work if it isn’t the same as the invoice date. |
| Notes | How to pay (bank details or payment link), the reference to use, and anything agreed, such as a late payment charge. |
VAT, sole traders and limited companies (UK)
- Not VAT-registered? Leave the Tax / VAT rate at 0 and don’t show a VAT number. You can’t charge VAT unless you’re registered.
- VAT-registered? Enter your rate (20% is the standard rate) and put your VAT number in your details. If you’re also charging for delivery, VAT usually applies to that too; the generator adds it automatically, because “Add tax / VAT to shipping” is ticked by default.
- Sole traders need their own name on the invoice as well as any business name, plus an address where legal documents can be sent.
- Limited companies must use the full company name exactly as it appears on the certificate of incorporation. If you list any directors’ names, you must list them all.

If an invoice isn’t paid on time
When you invoice another business and payment is late, UK law lets you claim interest of 8% a year above the Bank of England base rate, plus a fixed sum towards the cost of chasing it:
| Amount owed | Fixed sum you can claim |
|---|---|
| Up to £999.99 | £40 |
| £1,000 to £9,999.99 | £70 |
| £10,000 or more | £100 |
These rules apply between businesses, not to invoices for private customers. Source: GOV.UK, Late commercial payments: charging interest and debt recovery. A polite reminder a few days before the due date usually works better than any of this.
Frequently asked questions
What goes into the invoice and how the totals are worked out. Our guide on how to write an invoice covers what UK invoices must include. From 1 April 2029, under HMRC’s published plans, VAT invoices between VAT-registered UK businesses must be structured e-invoices rather than just PDFs (see GOV.UK’s Roadmap for e-invoicing implementation and our guide to what is changing).
