Tips for Effective Follow-Up
- Stay professional. Firm is fine; aggressive rarely helps. Assume oversight first.
- Reference the invoice number. Always include it. Makes it easy for the client to find and process.
- Make it easy to pay. Re-attach the invoice or include payment details if helpful.
- Offer payment plans for large amounts. If the client is struggling, a plan may get you paid faster than a standoff.
Tools like InvoiceBlitz help you track which invoices are paid and which are overdue, so you know when to send each follow-up.
