How to Invoice as a Freelancer

Invoice the day you deliver

The single highest-leverage change most freelancers can make is to stop batching invoices at month end. An invoice sent the day the work lands arrives while the client still remembers approving it, and it starts the payment clock up to four weeks earlier.

Ask for a deposit

For anything longer than a week or two, a deposit invoice before starting is standard and rarely refused. It covers your exposure, and a client who will not pay a deposit is telling you something useful about how they will treat the final invoice.

Make the terms specific

Fourteen days is a reasonable default for a solo supplier. Negotiate the terms before the engagement, not after the first invoice goes unpaid — at that point you have no leverage and the conversation is adversarial.

Follow up on a schedule, not a feeling

Decide the cadence in advance and run it regardless of how awkward it feels, because a predictable process is far easier to sustain than a decision made each time.

• Three days before the due date: a short, friendly reminder
• On the due date: a note that payment is now due
• Seven days overdue: a firmer message referencing your terms
• Fourteen days overdue: apply the late fee and escalate to a named finance contact

Keep everything

Every invoice PDF, every acceptance email, every scope change. It is dull filing that does nothing at all until the one occasion it does everything.
