InvoiceRemind Alternative: Dun

InvoiceRemind (chaseinvoices.com) provides basic invoice payment reminder functionality. If all you need is a simple nudge when an invoice is overdue, it can work for that purpose.

Dun takes a different approach. Instead of sending the same reminder repeatedly, Dun runs a 7-stage escalation sequence that automatically increases urgency over time. Early stages are friendly. Later stages are firm. The final stage sends a formal demand letter.

Feature comparison

Reminders vs. escalation

The core difference is what happens after the first reminder. With a basic reminder tool, you send a notification and hope for the best. If the client does not respond, you are back to manually following up.

With Dun, escalation is automatic. Each stage follows the previous one at a set interval, and the tone shifts from friendly to formal. You can preview every email before it goes out. If a client pays at any point, Dun stops the sequence immediately.

Why Dun at $14.99/mo

Dun connects directly to your invoicing platform. Overdue invoices are imported automatically. You do not need to manually enter invoice details or set up individual reminders. The entire process, from detection to demand letter, runs on autopilot.
