Stop chasing. Start collecting.
Your buyer is already legally liable.

If you're Udyam-registered and your client hasn't paid in 45 days, the MSMED Act entitles you to 16.5% compound interest — and their tax deduction is blocked until they pay. Papagye sends the reminders automatically. You never follow up again.

Add your invoice once (takes a minute). Papagye tracks the due date, sends escalating reminders to your client on Day 15, Day 30, Day 45 — and on Day 46, your email cites Section 16 of the MSMED Act and the exact interest accruing daily. No WhatsApp. No spreadsheet. No awkward calls. Just a paper trail your client's auditor will notice. Works with any invoice you already raise. Nothing to migrate.

The 45-Day Rule — in plain language

The MSMED Act, 2006 (Micro, Small and Medium Enterprises Development Act) protects Udyam-registered Micro and Small enterprises from delayed payment. Here's what it says:

Section 15 — Payment Deadline

  • With a written agreement: payment must be made within 45 days of delivery/acceptance.
  • No written agreement: payment is due within 15 days.
  • The buyer cannot unilaterally extend this deadline by contract. Any clause purporting to extend beyond 45 days is unenforceable against a Micro/Small enterprise.

Section 16 — Statutory Interest (non-waivable)

  • If payment is not made by the Section 15 deadline, compound interest at 3× the RBI Bank Rate begins accruing automatically — from the day after the deadline.
  • Current RBI Bank Rate: 5.50% → Statutory interest rate: 16.50% p.a., compounded monthly.
  • This interest is a statutory right. No private agreement or contract clause can waive it. The non-obstante clause in §16 overrides any conflicting contract term.
  • Applies only to Micro and Small enterprises with valid Udyam registration predating the invoice. Medium enterprises and traders are excluded from the §15–16 route.

Section 43B(h) — Income Tax Act (AY 2024-25 onwards)

  • The buyer cannot claim a tax deduction for the amount owed to you until actual payment is made.
  • If your invoice crosses the MSMED Act deadline unpaid, the buyer's taxable income increases by that amount.
  • This is a buyer-side consequence that a well-worded reminder email — citing §43B(h) — will make their finance team notice.

How to Calculate Statutory Interest

Formula (MSMED Act §16, compounded monthly):

Interest = P × (1 + r/12)^n − P

Where: P = principal (invoice amount), r = 0.165 (16.5% annual = 3× RBI Bank Rate 5.50%), n = number of months overdue

Example: ₹50,000 invoice, 60 days late (~2 months)

Invoice AmountDays OverdueStatutory InterestTotal Legally Owed
₹50,00030 days (1 month)₹688₹50,688
₹50,00060 days (2 months)₹1,384₹51,384
₹50,00090 days (3 months)₹2,089₹52,089
₹1,00,00060 days (2 months)₹2,769₹1,02,769

Frequently Asked Questions

Who qualifies for MSMED Act §15–16 protection?

Only Micro and Small enterprises with a valid Udyam registration (udyamregistration.gov.in) that predates the invoice. Medium enterprises and traders are excluded from the §15–16 interest route. If you have a Udyam certificate, you almost certainly qualify as Micro or Small.

My buyer says our contract allows 60 days. Does §16 still apply?

Yes. Section 16 has a non-obstante clause — it overrides any private agreement. A contract clause granting more than 45 days is unenforceable against a Micro or Small enterprise. The statutory rate applies from Day 46 regardless of what your contract says.

Can I waive the interest to maintain the client relationship?

Legally, you can choose not to claim it, but no clause in your contract can obligate you to waive it in advance. You retain the statutory right — and the mere mention of it in a reminder email is often enough to accelerate payment.

What is MSME Samadhaan?

The government's free online dispute resolution portal at odr.msme.gov.in. You can file a case without a lawyer. The Micro and Small Enterprises Facilitation Council (MSEFC) award is enforceable as a civil court decree. Papagye's Day 46+ emails mention this portal to signal to your client that escalation is real and free.

Do I need to migrate my invoicing software?

No. Papagye works alongside whatever you use — paste the invoice number, amount, and client email. We track the dates and send reminders. Nothing changes in your existing workflow.

Is Papagye sending emails from my address?

Reminders are sent from Papagye's verified sender on your behalf and are clearly attributed to you (your name, your invoice number). Your client knows these are your reminders, automated.

Your invoices are protected by law. Make sure your clients know it.
