UPI Chargeback & Dispute Process for Merchants in India — How It Works

Merchants who have faced card chargebacks — where a customer files a claim and money is immediately pulled back pending investigation — often worry UPI will work the same way. Fortunately, UPI’s dispute architecture is meaningfully different and generally more protective of merchants for legitimate transactions. Here is how the system actually works.

UPI Disputes vs Card Chargebacks: The Fundamental Difference

The card chargeback system, designed decades ago, allows customers to dispute charges through their issuing bank. The bank provisionally credits the customer and the burden shifts to the merchant to prove the sale was legitimate. Money moves immediately against the merchant.

UPI operates differently:

• UPI is a push payment — the customer initiates and authorises the payment. There is no “pull” mechanism where a third party reverses your settled funds without going through a defined process.
• Merchant consent is required for any reversal of a completed legitimate transaction.
• The NPCI dispute framework adjudicates contested cases rather than automatically favouring the customer.

This architecture makes UPI significantly more merchant-friendly for disputes over delivered goods and services.

NPCI’s UDIR: Unified Dispute and Issue Resolution

NPCI operates the UDIR (UPI Dispute and Issue Resolution) system, which handles two categories of issues:

Category 1: Technical Failures

• Transaction declined but customer debited
• Partial credit (customer debited for ₹5,000 but merchant received ₹3,000)
• Duplicate charges
• Timeout errors where bank debited customer but no credit posted to merchant

These are not merchant disputes — they are system errors. Banks have automated reconciliation processes to handle these. The customer’s bank must reverse the debit within T+5 business days under RBI’s October 2019 circular on failed transactions (Circular DPSS.CO.PD No.629/02.01.014/2019-20).

Category 2: Customer-Initiated Disputes

• “I made a payment but goods were not delivered”
• “Wrong amount charged”
• “I did not make this payment (alleged unauthorized transaction)”
• “Merchant refuses refund for returned goods”

These involve a formal dispute process with defined timelines and merchant response windows.

The UDIR Dispute Process: Step by Step

Step 1: Customer raises complaint through their UPI app (PhonePe, Google Pay, etc.) or calls their bank. Time limit: 30 days from transaction date for most dispute types.

Step 2: TPAP/Bank routes to merchant’s bank. The complaint travels through the UPI network — customer’s TPAP → NPCI UDIR system → merchant’s acquiring bank → merchant.

Step 3: Merchant is notified and given a response window. Merchants are typically given 3-5 business days to submit evidence — delivery proof, invoice, chat logs, tracking confirmation, signed acknowledgment from customer.

Step 4: NPCI/bank adjudicates. If the merchant provides adequate evidence of delivery, the dispute is rejected and no reversal occurs. If the merchant provides no response, the dispute may be resolved in the customer’s favour.

Step 5: Resolution. The entire cycle should complete within T+5 business days from the date the dispute was formally raised (per NPCI circular NPCI/2020-21/UPI/Circular No. 139).

Types of Disputes and How Merchants Should Respond

Wrong amount disputes: Provide the original transaction record showing the UPI transaction ID and the amount. If you use dynamic QR (amount pre-set), the QR data serves as evidence.

Non-delivery disputes: Provide delivery challan, courier tracking, photos of delivery, or customer acknowledgment. For digital goods, server logs showing download or access.

Unauthorized transaction claims: These are the most sensitive. If a customer claims they did not authorise a payment, NPCI investigates whether the PIN was correctly entered and no system compromise occurred on the TPAP side. For merchants, evidence of the customer physically present at the store (CCTV, POS system logs) is valuable.

Refund disputes: If you promised a refund but did not issue it, or issued it to the wrong UPI ID, provide refund transaction records.

RBI Integrated Ombudsman: The Escalation Path

If the TPAP or bank fails to resolve the dispute within the prescribed timeline, customers can escalate to the RBI Integrated Ombudsman under the scheme launched in November 2021.

The Ombudsman has jurisdiction over:

• Failure to resolve complaints within 30 days at the regulated entity level
• Deficiency in service by payment system operators

For merchants, an Ombudsman proceeding is more serious — the RBI can direct a merchant’s acquiring bank to ensure refund or other remedies. However, the Ombudsman scheme is designed to address systemic failures, not routine commercial disputes.

Why UPI Disputes Are More Merchant-Friendly Than Card Chargebacks

Several structural features benefit merchants:

1. No automatic fund reversal: Unlike card chargebacks where money is provisionally debited from the merchant account, UPI holds funds in place pending resolution.

2. Push payment evidence: Because the customer authorised the payment using their own UPI PIN (which no third party knows), “I didn’t do this” claims face a higher evidentiary bar.

3. Shorter customer complaint window: Many UPI TPAPs allow disputes only within 30-45 days of the transaction. Card chargeback windows can be 120-180 days.

4. No chargeback fees: Card networks typically charge merchants ₹500-₹2,000 per chargeback dispute regardless of outcome. UPI disputes carry no equivalent penalty fee.

Best Practices for Merchants to Minimise Disputes

• Use dynamic QR with pre-set amounts to eliminate wrong-amount claims
• Send digital receipts via SMS or WhatsApp immediately after payment — these serve as acknowledgment records
• For delivery businesses, collect customer signature on delivery confirmation
• Maintain transaction logs with customer UPI ID, amount, timestamp, and item description for at least 2 years
• For high-value transactions, request the customer to note the transaction reference number before goods are handed over

UPI’s dispute architecture rewards organised merchants. The better your transaction records, the more confidently you can respond to any disputed claim.
