Use plain language, specific deliverable names, and dates your client will recognize. Attach a brief, friendly summary of what was delivered, linking to milestones or artifacts so accounting teams can approve quickly. Include tax identifiers, addresses, and purchase order numbers if your client requires them. Consistency reduces back-and-forth. A solo designer named Maya cut her average collection time in half simply by adding client-side tags and a short handoff note to every invoice.
Set polite, staged reminders that escalate gently: a friendly note before due date, a respectful nudge a few days after, and a concise summary for finance contacts if needed. Personalize tone and sign-off once, then let automation reuse your voice. Include fresh payment links each time, avoiding expired tokens. When a client pays, send a warm thank-you automatically. It is simple courtesy that also nudges repeat work and long-term trust.
