Small collectors either never retry failed NACH debits or retry every failure, wasting fees on mandates that can never succeed.
Retry only temporary failures, such as low balance or technical errors, a few business days later under the same UMRN; route dead mandates to a new mandate or another payment mode.
Return reason list mapped to retry or new-mandate, retry dates and count per UMRN, fee tracking, and customer messages before each retry.
Higher recovery on temporary failures, fewer wasted fees, and a clean record of every attempt against each UMRN.
Yes, for temporary failures such as low balance or a technical error. Present the debit again under the same mandate, usually within the same billing cycle and your sponsor bank’s retry limits. No for dead mandates: a cancelled mandate, a closed or frozen account, or a debit above the mandate maximum needs a fresh mandate or another payment route.
Which failures can I retry?
| Failure reason (in words) | Retry or new mandate | When to retry | What to tell the customer |
|---|---|---|---|
| Insufficient balance | Retry | Typically 3 to 5 business days later, or just after salary date | Amount, new date, request to fund the account |
| Technical failure at a bank | Retry | Next batch date | Usually nothing, or a short note |
| Debit above mandate maximum | New mandate | Do not retry | Ask for a new mandate with a higher cap |
| Mandate cancelled by customer | New mandate or other mode | Do not retry | Ask for a new mandate or UPI or NEFT payment |
| Account closed | New mandate on new account | Do not retry | Ask for new account details |
| Account frozen or blocked | Wait for customer | Do not retry until resolved | Ask customer to resolve with their bank |
| Details mismatch | Correct and re-register | After correction | Confirm account details |

How many retries, and how far apart?
There is no single rule for every collector. Practice varies by sponsor bank and by lender policy. A common pattern is up to two retries within the same billing cycle, three to five business days apart. Confirm the limit with your sponsor bank and write your own policy down.
Time retries well. If a customer’s salary lands on the 1st, a retry on the 2nd or 3rd of the next month may be too late for this cycle, but a retry soon after mid-month bonus or business receipts may work. Ask the customer when funds will be in.
Do repeat failures cost money?
Usually. Each rejected presentation can carry a fee from your sponsor bank, plus 18% GST on that fee. The customer’s bank may also charge the customer a bounce fee. Banks set their own charges, so check your schedule of charges. That is why retries should be selective: two failed retries on a dead mandate cost twice and still collect nothing.
For the customer, a debit returned for insufficient funds can also have legal weight under Section 25 of the Payment and Settlement Systems Act 2007, which treats it in a way similar to a cheque bounce.
Worked example: a low-balance EMI
A small lender’s ₹12,500 EMI was presented on 5 November and returned on 7 November for insufficient balance. The sponsor bank charges an illustrative ₹250 return fee plus 18% GST of ₹45. The lender messages the customer, who confirms funds by the 11th. It re-presents on 12 November and collects ₹12,500.
Entries:
| Date | Entry | Amount |
|---|---|---|
| 5 November | EMI due: debit customer, credit interest income and principal per schedule | ₹12,500 |
| 7 November | Return: no receipt to post; customer stays overdue | ₹12,500 overdue |
| 7 November | Return fee: debit bank charges ₹250 and input GST ₹45, credit bank | ₹295 |
| 12 November | Retry collected: debit bank, credit customer | ₹12,500 |
Overdue days: 12 − 5 = 7. Total bank cost: ₹250 + ₹45 = ₹295. Whether the lender can recover a bounce charge from the customer depends on the loan agreement.
How do I keep track of every attempt?
Record each presentation against the UMRN: date, amount, result, reason and fee. A simple sheet with one row per attempt is enough for a small collector. It tells you how many retries each mandate has had, which reasons repeat, and what the failures are costing.
