How to Chase an Overdue Invoice

Why invoices go overdue (it is usually not personal)

Most overdue invoices are not a customer refusing to pay — they are a customer who lost the invoice, forgot it was due, or is waiting until you remind them. That means a clear, well-timed reminder is usually all it takes. The mistake is waiting too long to send the first one: a gentle nudge before the due date catches most people before they fall behind.

A simple reminder schedule

A short, predictable sequence works better than a single awkward message weeks later. A common cadence:

• A friendly reminder a few days before the due date ("just so it lands in time")
• A reminder on the due date itself
• A follow-up a few days after it becomes overdue
• A firmer reminder after a week overdue
• A final reminder after two weeks overdue

Each message should restate the amount, the due date and how to pay. Keep the tone professional and assume the customer intends to pay — most do once they are reminded.

What to say in an overdue reminder

Keep it short and clear. State the invoice number and amount, the original due date, the payment details, and a simple ask. Avoid guilt or anger — the goal is to make paying the easiest thing the customer does that day. A line like "I wanted to make sure this hadn't slipped through — here are the details again" works far better than "You still haven't paid."

Make it easy to pay

The single biggest cause of slow payment is a hard-to-find payment method. Put your bank details, reference and the exact amount on every reminder and on the invoice itself. The fewer steps between the customer reading the reminder and the payment leaving their account, the faster you get paid.

How Quoteza helps

Quoteza sends invoices as a link and shows you when they have been viewed, so you know who to chase. You can switch on automatic reminders at the points above — before the due date, on the due date, and at increasing intervals once overdue — and Quoteza emails the customer for you, with your payment details included, so chasing stops being something you do by hand.
