Count how many days an invoice is overdue from its due date to today — the number you need before chasing or claiming interest.
Frequently asked
When can I start charging interest on a late invoice?
If you’re a registered micro/small enterprise, the MSMED Act allows interest once payment is more than 45 days late. Otherwise it depends on a late-fee clause in your contract.
Retainer shows the days-overdue on every unpaid invoice and turns it into an automatic reminder, so nothing quietly ages past 45 days. Try Retainer free
