Frequently Asked Questions
A full VAT invoice must include: your business name, address and VAT registration number; a unique invoice number; invoice date and tax point; customer name and address; description of goods/services; quantity and unit price; VAT rate and amount for each item; and total amount including VAT. Simplified VAT invoices (for amounts under £250) don't need all of these.
For most VAT-registered businesses, a VAT invoice must be issued within 30 days of the supply of goods or services (or 30 days from receipt of payment for continuous services). Issuing invoices promptly is also important for cash flow. Late invoicing is one of the biggest causes of payment delays for small businesses.
Yes. Under the Late Payment of Commercial Debts Act, businesses can charge 8% above the Bank of England base rate on overdue B2B invoices. You can also claim a fixed late payment compensation charge (£40 for debts under £1,000; £70 for £1,000-£9,999; £100 for £10,000+). Many businesses include payment terms in their invoice footer.
No. Any business can issue invoices. However, only VAT-registered businesses should charge VAT. If you're not VAT registered (turnover under the £90,000 threshold), issue invoices without VAT. If you are VAT registered, you must issue a proper VAT invoice for all B2B transactions and VAT-registered customers.
