What to Include on a Tradesperson's Invoice
An invoice has one job: to get you paid, in full, without a follow-up conversation. Most late payments are not malice, they are friction. The customer cannot find your bank details, is not sure what the bill covers, or is waiting for a proper document for their own records. A complete invoice removes every excuse.
The essentials every invoice needs
Whatever your trade, the same core elements apply:
- Your business name and address, plus a phone number or email
- The customer's name and address (and the site address if different)
- A unique invoice number and the invoice date
- A clear description of the work done, matching the quote where there was one
- The amount charged, with materials and labour shown separately where useful
- Your payment terms and the due date
- How to pay: bank details, or a payment link if you take card payments
The description of work deserves care. "Building work: £2,400" invites questions; "Supply and fit 12m of close-board fencing including posts, gravel boards and disposal of old panels, as quoted: £2,400" answers them before they are asked. If the job was quoted, echo the quote's wording and reference its number, so the customer can see the invoice matches what they agreed.
VAT: only if you are registered
This is the conditional part, and it matters. If you are VAT registered, your invoice must also show your VAT registration number, the VAT rate applied, and the VAT amount broken out from the net, with the gross total stated. If you are not registered, none of that appears: you do not charge VAT and you do not mention a VAT number. Mixing this up in either direction causes real problems, so get it right for your situation. If you are anywhere near the threshold or unsure of the detail, our VAT guide covers the basics and points you to gov.uk.
Why a clear invoice gets paid faster
Customers pay the invoice that asks the least of them. Bank details printed on the document mean no chasing you for them. A stated due date, phrased as "payment within 7 days of invoice date" or similar, gives them a deadline and gives you a reference point if you need to remind them. Send the invoice promptly: the day the job finishes, while the customer is still pleased with the work, is when payment comes easiest. A week later it is admin; a month later it is a chase.
Payment terms that actually work
Keep the phrasing plain. "Payment within 7 days of invoice date by bank transfer to the account below" is better than anything legalistic on a domestic job. Commercial customers will often expect 30 days, and some will stretch it whatever you write, so on commercial work the terms matter even more because they are what any late-payment conversation hangs on.

Do my invoices legally need an invoice number?
For VAT-registered businesses, a unique sequential invoice number is a legal requirement. For everyone else it is still strongly advised: numbers make your records, your tax return and any payment chase far easier. Pick a system and never reuse a number.
Do I have to show VAT on my invoice?
Only if you are VAT registered. If you are, the invoice must show your VAT number and the VAT amount broken out at the correct rate. If you are not registered, you must not charge VAT or show a VAT number, and no VAT lines should appear at all.
What payment terms should I put on a trade invoice?
Whatever you genuinely expect, stated plainly: payment on completion, within 7 days, or within 14 days are all common for domestic work. Commercial customers often expect 30 days. The important thing is that a due date exists on paper, because it is the reference point for any reminder you send later.
Can I send an invoice by email as a PDF?
Yes, and for most trade work it is the fastest route. A PDF invoice attached to a short, polite email reaches the customer the day the job finishes, which is exactly when they are most inclined to pay. Keep a copy of both the invoice and the email for your records.
