Invoice basics for UK small businesses
A good invoice should clearly show who is being charged, what was supplied, the invoice date, the amount due, payment terms, a unique invoice number and VAT details if you are VAT registered. A good invoice is a payment tool and a record. It should tell the customer exactly what they are paying for, when payment is due, how to pay, which business issued it, and what evidence supports the charge. Cleaner invoices reduce disputes and improve cash flow. A plain-English invoice guide for small businesses that want cleaner records and fewer payment delays.
