Do Self-Employed People Need to Send Invoices?

Strictly speaking, self-employed sole traders aren't legally required to issue invoices to non-VAT-registered customers. However, invoices are essential for record-keeping and are required if you're VAT registered. Even if you're not, professional invoices help you:

• Get paid faster (clients know exactly what to pay)
• Keep clean records for your Self Assessment tax return
• Look professional and build trust
• Prove income if applying for mortgages or loans
