Freelancers get paid for shipped work, not for hours that live only in a chat thread. A short invoicing habit keeps cash predictable and conversations professional.
Agree the commercial details first
Before you start, confirm scope, rate, currency, and payment timing. If a client needs a purchase order, ask for it early. It is harder to add after you already sent files.
Invoice at a natural milestone
Bill when a phase is accepted, not when you feel awkward asking. For retainers, pick a calendar date and stick to it. For one-off jobs, invoice as soon as the deliverable is sent.
Keep a simple numbering system
Use a prefix plus a rising number, such as IB-1042. Do not reuse numbers. Save a draft on your device if you will finish the invoice later.
Write line items a stranger can understand
Finance teams often never saw the Slack thread. “Brand identity package — logo concepts and final files” is clearer than “Design work.” Include hours or units if that is how you priced the job.
Send a PDF they can forward
A live preview helps you catch missing tax or the wrong client name. Download the PDF and send it with a short email: what the invoice is for, the amount due, and the due date.
