How to make an invoice in 6 steps.
Common invoicing mistakes.
Reusing or skipping invoice numbers
Duplicate or missing numbers cause bookkeeping chaos and disputes. Always use a unique, sequential reference for every invoice.
No clear due date
Vague terms are the number-one cause of late payment. State an exact due date or terms like "Net 14" or "Due on Receipt".
Leaving off payment instructions
If clients cannot see how to pay you, they delay. Include bank details, IBAN, or a payment link directly on the invoice.
Getting the tax wrong
Apply the correct VAT, GST, or sales tax for your region, and state whether tax is included in your prices or added on top.
Manual math errors
Hand-calculated totals invite mistakes. Use a generator that totals subtotals, tax, and discounts automatically.
Not keeping a copy
You need invoices for accounting and tax. Always save a PDF copy of every invoice you send.
