How to actually claim this
- Send a formal reminder with this exact figure. Mention MSMED Act §16 if you’re Udyam-registered.
- If unpaid after 15 days, file a complaint with the MSME Samadhan portal (free).
- Or invoice the interest as a separate line on your next bill — many clients pay rather than argue.
