1. Introduction

A payment gateway contract is an agreement between merchants, payment aggregators, banks, and service providers enabling online transactions. Disputes arise due to the complex, multi-party nature of these arrangements involving technology, finance, and regulatory compliance.

2. Common Causes of Disputes

Transactions debited but not credited to merchant accounts
Settlement delays beyond agreed timelines

Gateway outages leading to loss of business
Breach of Service Level Agreements (SLAs)

(d) Unauthorized Transactions / Cybersecurity Breaches

Data breaches or hacking incidents
Non-compliance with PCI-DSS standards

(e) Fee and Commission Disputes

Hidden charges or unilateral fee changes
Disputes over MDR (Merchant Discount Rate)

(f) Termination and Withholding of Funds

Sudden suspension of merchant accounts
Retention of rolling reserves

3. Legal Issues Involved

(i) Breach of Contract

Failure to comply with settlement timelines, uptime guarantees, or security obligations.
