Invoice Late Fee and Interest: How Much Can You Charge in India?

Yes, you can charge interest on late invoice payments in India. Learn the legal basis, MSMED Act protections, and how to communicate it to customers.

Can you legally charge late payment interest?

Yes — if the rate and trigger are clearly mentioned in your contract, purchase order, or on the invoice itself. Without prior notice, courts may not enforce the late fee.

MSMED Act protection for small suppliers

If you're a registered MSME, the Micro, Small and Medium Enterprises Development Act mandates payment within 45 days. Beyond that, the buyer must pay compound interest at 3x the bank rate notified by RBI.

Reasonable interest rates

Typical industry practice: 1.5%–2% per month (~18%–24% annualised) for B2B. Banking rates apply for MSMEs under MSMED. Anything above 24% may be seen as usurious.

How to communicate it

On every invoice footer: "Interest at 1.5% per month will be charged on payments not received within 30 days from the invoice date." Send a written reminder 7 days after due date before applying interest.

Automate reminders

Most disputes happen because customers genuinely forget. Set up 3-stage automated WhatsApp/email reminders (1 day before due, on due, 7 days after) in your billing software to dramatically reduce DSO.
