What Is It?
A trade invoice is a formal document sent to a customer requesting payment for completed work. It itemises the labour carried out, materials and parts supplied, hours worked, applicable VAT, and the total amount owed. It serves as both a payment request and a legal record of the transaction, which is important for tax reporting, warranty claims, and resolving any disputes about the work performed. Every trade business needs a clear, consistent invoice to look professional and stay compliant.
About This Template
A professional invoice is essential for any tradesperson running a legitimate business, whether you are an electrician, plumber, builder, carpenter, or window cleaner. For VAT-registered businesses, HMRC requires invoices to include specific details such as your VAT number, the VAT rate applied, and the total VAT charged. Beyond legal compliance, a well-designed invoice builds trust with customers, presents your business as credible and established, and ensures you get paid on time. Using a consistent invoice template also simplifies your bookkeeping and makes filing your self-assessment or corporation tax return far less stressful at the end of the year.

Tips
Number your invoices sequentially (for example INV-001, INV-002) and never reuse a number — HMRC expects a clear, unbroken audit trail
Set clear payment terms upfront, typically 14 days for domestic work and 30 days for commercial clients, and state them on every invoice
Use professional formatting with your logo and brand colours to reinforce your business identity and look established
Keep digital and physical copies of every invoice for at least six years, as required by HMRC for self-assessment and tax records
Send the invoice promptly after finishing the job — the longer you wait to invoice, the longer you wait to get paid
