Indian P2P runs on three main payment rails: UPI, IMPS, and NEFT. Most P2P merchants list UPI; most large trades use IMPS; NEFT is the slow-and-steady option. Which to use depends on size, time, and how your bank views crypto-adjacent transfers.
UPI — fast, small, scrutinised
UPI is instant (under 30 seconds) and free. Per-transaction limits are ₹1 lakh on most apps (₹2 lakh on some merchant accounts). 24/7 availability.
Catch: NPCI logs every UPI transaction, and banks run pattern detection on UPI transfers. Frequent transfers to the same merchant ID, or sudden high-volume UPI activity, can trigger account reviews.
IMPS — fast, larger, less scrutinised
IMPS is near-instant (1-5 minutes), 24/7, and supports up to ₹5 lakh per transaction. Banks generally apply less aggressive AML detection on IMPS than on UPI because the user base is broader (business payments, salary, etc.).
Use when your single trade is above the ₹1 lakh UPI cap.
NEFT/RTGS — bigger size, slower
NEFT settles in batches (every 30 minutes, 24/7 since 2019). RTGS is real-time but only for transactions ≥₹2 lakh, working hours only.
Most P2P merchants discourage NEFT because of the lag — they may decline ads to NEFT-only buyers. RTGS is fine for big-ticket trades during banking hours.
Bank transfer (manual)
Direct bank-to-bank transfer via netbanking. Slower than IMPS, no real upside vs IMPS for retail. Useful only if your account doesn't support IMPS for some reason.
Key takeaways
- UPI for trades under ₹1L; instant and free, but most-watched.
- IMPS for trades ₹1L-₹5L; almost as fast, less AML pressure.
- RTGS for ₹2L+ during banking hours.
- NEFT rarely accepted by P2P merchants due to lag.
