To chase an unpaid invoice effectively, send a polite first reminder at D+7 after the due date, a firmer second at D+15, then a formal notice at D+30. Consistency matters more than severity: most late payments are settled at the first reminder.
Why chase early (and without guilt)
A late payment is almost never a refusal to pay — it’s an oversight. The longer you wait, the deeper the invoice sinks in the pile. Chasing at D+7 reads as normal and professional, not as nagging.
The three-step schedule
D+7: friendly reminder. D+15: more direct, with amount and date. D+30: formal notice, mentioning late-payment interest. Each step has its template, in your customer’s language.
Automate without losing the right tone
Rewriting these emails by hand costs time, and you end up forgetting. Ordavena sends the reminders on your schedule, with your templates, and stops as soon as the invoice is paid — you stay in control, the machine handles the consistency.
