Invoicing

What to include

• Your business name and any registration number your country requires.
• The customer’s details.
• An invoice number and date.
• What you supplied, quantities and prices.
• Tax shown separately where required, e.g. GST or VAT.
• The total, due date and how to pay.

Getting paid on time

• Agree payment terms before you start work.
• Invoice promptly and make paying easy.
• Send a polite reminder when payment is due, and follow up if it’s late.

When to move to invoicing software

• You send the same invoice every month and want it to go automatically.
• You want automatic reminders for late payments.
• Customers want to pay online by card or bank transfer from the invoice.
• Your accountant wants invoices to flow straight into your books.

Tax invoice rules vary by country — check your tax authority’s requirements. KitWren’s GST/VAT calculator helps with the sums; quotes and receipts use the matching generators.
