Frequently asked questions
When should I send a payment reminder?
Send a courtesy reminder 3-7 days before the due date, then immediately when payment becomes past due, and follow up at 15, 30, and 45-day intervals. Consistent follow-up improves collection rates.
Should I charge late fees?
Late fees are an effective incentive for timely payment, but they should be disclosed upfront (on the invoice or in your contract). Check your state laws for any limits on late fees.
How do I keep the tone professional but firm?
Start with friendly reminders assuming the oversight was unintentional. As time passes, become more direct about consequences. Always maintain professionalism—never be threatening or rude.
What if the customer says they cannot pay?
Offer a payment plan with scheduled installments. Get the agreement in writing. Some payment is usually better than no payment and pursuing collections.
Should I send reminders by mail or email?
Email is faster for routine reminders. Use certified mail for final notices or when you need proof of delivery for potential legal action or collections.
When should I escalate to collections or legal action?
Most businesses escalate after 60-90 days of non-payment with no communication. Before escalating, send a final notice warning of the consequences and give a last chance to pay.
