What is NACH (and an e-NACH mandate)?
NACH (National Automated Clearing House) is NPCI's system for bulk, recurring payments. It handles credits like salaries and dividends, and debits like loan EMIs and SIPs. For a debit, the customer first signs a mandate. e-NACH is the paperless version, authenticated through net banking, a debit card or Aadhaar.
NACH NPCI ka system hai jisse har mahine EMI, SIP ya bill apne aap account se katta hai. Iske liye pehle mandate sign karna hota hai. e-NACH mein yeh mandate online net banking ya debit card se ho jata hai, kagaz ki zarurat nahi.
How a NACH debit works
- The customer registers a mandate: max amount, frequency and validity, with the lender or merchant as 'sponsor'.
- The destination bank verifies and accepts the mandate.
- On each due date, the sponsor bank presents the debit through NACH.
- The customer's bank debits the account, or returns it with a reason code.
Why NACH debits bounce
Common return reasons: insufficient balance, the account being closed or frozen, a mandate cancelled by the customer, or an amount above the mandate limit. A bounced EMI usually attracts a bank charge and a lender's bounce fee, and it starts the DPD count. That is why lenders send reminders before the presentation date.
NACH vs UPI AutoPay vs standing instruction
A standing instruction is set up inside one bank and only works for that bank's accounts. NACH works across banks and is the default for loan EMIs. UPI AutoPay is the fastest to set up and suits smaller recurring payments. Collections teams track mandate health, because a cancelled mandate is an early warning sign.
