Small businesses use the word auto-debit for several different rails and cannot tell from the bank statement which rail collected or failed.
Map each recurring collection to its rail: NACH or eNACH mandate, UPI AutoPay, card e-mandate, or a payer-side standing instruction; each has its own set-up, cap, failure signal and narration.
A mandate register listing rail, customer, amount cap, frequency, start and end date and mandate reference for every recurring collection.
Every recurring credit or failure on the bank statement traced to its rail and mandate, with the right follow-up for each.
Auto-debit is a permission a customer gives once so that a business or lender can collect money from their account on set dates without a fresh approval each time. In India it runs mainly on three rails: NACH (paper or online as eNACH), UPI AutoPay, and card e-mandates. A bank standing instruction looks similar but is different: there, the customer’s own bank pushes the money out on the customer’s order.
How do the rails compare?
| Rail | Who sets it up | Who presents the debit | Cap and authentication | Failure signal | On the statement |
|---|---|---|---|---|---|
| NACH (paper) | Customer signs a mandate form; business submits via its sponsor bank | Business, through NPCI’s NACH batches | Maximum amount written on the mandate | Return file from the bank, by mandate reference (UMRN) | Debit narration with the business’s name and UMRN |
| eNACH | Customer authenticates online (net banking, debit card or Aadhaar) | Business, through NACH batches | Mandate maximum set at registration | Same return file | Same as paper NACH |
| UPI AutoPay | Customer approves once in a UPI app | Business, through its payment gateway or bank | Up to ₹15,000 per debit without extra authentication; ₹1 lakh for insurance premiums, mutual fund subscriptions and credit card bills | Failed status from the gateway | UPI debit narration |
| Card e-mandate | Customer registers card with the merchant | Merchant, through card network | Up to ₹15,000 without extra authentication | Gateway failure status | Card statement, not bank account |
| Standing instruction | Customer instructs their own bank | Customer’s bank | Whatever the customer sets | Customer’s bank notes it | Transfer narration |
Under RBI’s e-mandate framework for cards and UPI, the customer gets a pre-debit notification at least 24 hours before each debit and can opt out.
How is a standing instruction different from a mandate?
With a standing instruction, you tell your own bank: “Every month on the 1st, send ₹20,000 to my landlord.” The bank pushes the money. Nobody else can pull from your account.
With a mandate, you let a third party, such as a lender, insurer or subscription business, pull money. They decide when to present each debit within the limits you approved. That is why a mandate carries a reference number (the UMRN for NACH) and why returns come back to the business.
Which rail suits which collection?
- Loan EMIs from ₹5,000 upward: typically NACH or eNACH, because amounts and tenure are long and fixed.
- Insurance premiums and mutual fund SIPs: NACH and, increasingly, UPI AutoPay within its higher ₹1 lakh category limit.
- Small subscriptions such as ₹149 to ₹999 OTT or software plans: UPI AutoPay or card e-mandates, because set-up is quick in an app.
- Rent and family transfers: standing instructions, since the payer controls them.
Worked example: two auto-debits on one statement
A small business owner has a ₹12,500 monthly loan EMI collected by NACH on the 5th, and a ₹499 software plan collected by UPI AutoPay on the 5th. On 5 November the bank statement shows:
- A NACH debit of ₹12,500 with the lender’s name and a 20-character UMRN.
- A UPI debit of ₹499 with the software company’s name.
Total auto-debits that day: ₹12,500 + ₹499 = ₹12,999. In the books, ₹12,500 splits between loan principal and interest per the lender’s schedule, and ₹499 goes to software expense (with GST input if a tax invoice is received).
If the ₹499 debit fails, the software company sees a failed status from its gateway and may retry. If the ₹12,500 NACH debit fails, the lender receives a return in its bank’s return file.
Is auto-debit free?
For the customer, usually yes. For the business, NACH presentations and returns carry charges set by its sponsor bank, and gateways may charge a platform fee on UPI AutoPay. Under Section 25 of the Payment and Settlement Systems Act 2007, a debit that fails for insufficient funds can be treated as an offence similar to a cheque bounce, so customers should keep mandates funded.
