 "method": "Approximate combined (Credit + Debit) per-month run-rate of NACH transactions by fiscal year, with the platform's structural facts (NPCI-operated centralised bulk-clearing under the PSS Act 2007; NACH Credit vs NACH Debit; physical-NACH vs e-NACH mandate with a defined cap/frequency/validity registered via the Mandate Management System with a UMRN; Sponsor Bank vs Destination Bank roles; Aadhaar Payment Bridge for DBT). The latest year is indicative/provisional.",
 "note": "Rounded, approximate and INDICATIVE; NOT in the Verified-numbers ledger pending reviewer sign-off. NACH is the NPCI-operated centralised bulk-clearing platform (launched 2013, progressively replacing the older Electronic Clearing Service / ECS), authorised under the Payment and Settlement Systems Act, 2007 under RBI oversight. NACH Credit = one-to-many push (salary, dividend, pension, DBT subsidy); NACH Debit = many-to-one pull (SIP, EMI, premium, utility). A debit needs a physical-NACH or e-NACH (Aadhaar/net-banking/debit-card) mandate with a defined cap/frequency/validity, registered via the Mandate Management System with a Unique Mandate Reference Number (UMRN); a stopped mandate halts all further debits. Distinct from the RBI card/UPI e-mandate framework. Combined run-rate approx 45 crore/mo (2019-20) -> ~100 crore/mo (2024-25, indicative).",

   "step": "1. Fix the role & flow",
   "detail": "Decide if the bank is the Sponsor Bank (presenting files for a registered corporate / originator) or the Destination Bank (processing against its own customers), and classify the flow as NACH Credit (bulk payout) or NACH Debit (bulk collection)"

   "detail": "A NACH Debit needs a customer authorisation - a physical NACH mandate or an electronically-authenticated e-NACH mandate - with a defined maximum amount, frequency and validity, accepted through the Mandate Management System (MMS) and assigned a UMRN"

   "step": "3. Present the file",
   "detail": "The Sponsor Bank uploads the input file; NPCI validates and routes each item to the Destination Bank, which debits / credits the customer account"

   "step": "5. Handle returns",
   "detail": "Unhonoured items (insufficient funds, account closed, mandate not registered, amount / frequency mismatch) are returned with standard NACH return reason codes within the return window; a cancelled / stopped mandate must halt all further debits"
