Common questions

What should be on a freelance invoice?

Your business name and contact, the client name, a unique invoice number, issue and due dates, itemized line items (description, quantity, rate), subtotal, tax if any, the total, and your payment terms including any late-fee policy.

When should I send an invoice?

Immediately — on project completion or at agreed milestones. Every day you delay invoicing is a day added to when you get paid.

How do I get clients to pay faster?

Three things: a clear due date (net-30 or less), late-fee terms printed on the invoice, and a follow-up schedule you actually keep — friendly at 7 days, firm at 14, late-fee notice at 30.
