Consulting invoice email template
Four copy-paste consulting invoice email templates for project billing, milestone invoices, monthly retainers, and polite overdue follow-ups. First invoice for a new project: introduce your invoicing process clearly. Reference the project name, the engagement letter or proposal, the invoice amount, and the payment due date. Include a direct link to the invoice. Milestone invoice: reference the specific milestone delivered, the phase name, and any sign-off from the client. State the amount due and the payment due date. Monthly retainer invoice: keep it short — state the retainer period, the monthly fee, and the due date. Clients on retainers expect consistency; a brief, professional email is best. Overdue follow-up: reference the invoice number and amount clearly, state the number of days overdue, and ask for payment or a response by a specific date. Keep the tone professional and factual — not apologetic. Every consulting invoice sent through Duevero includes a secure payment link clients can open in any browser. Eligible invoices can be paid online by card when you connect your Square account.
