How to write an invoice
What to include on an invoice, how to format it, common wording examples, mistakes to avoid, and a simple invoice example. Every professional invoice should include: your name and business name, your contact information (email and phone), the client's name and billing address, a unique invoice number, the invoice date, the payment due date (such as Net 15 or Net 30), itemized line items with clear descriptions and amounts for each service or deliverable, the subtotal, any applicable taxes, the total amount due, and your preferred payment method or a direct payment link. Formatting tips: use a clear, simple layout with your business name at the top. Make the total amount due prominent and easy to find. Include a payment link so the client can pay without any extra steps.
