Unified Payments Interface, or UPI, is an instant real-time payment system in India that enables bank-to-bank transfers using mobile applications, allowing users to send or receive money through simple identifiers like mobile numbers or UPI IDs.

UPI connects multiple banks on a single platform, allowing users to initiate payments directly from their bank accounts. Transactions are authorised using a PIN and processed instantly, 24/7. UPI supports peer-to-peer transfers, merchant payments, bill payments, and in-app collections, making it one of the most widely used digital payment systems in India.
UPI has transformed digital payments by making transactions fast, low-cost, and accessible. For businesses, UPI reduces dependency on cash and cards while improving payment success rates. Its real-time nature improves liquidity and customer experience, especially for high-frequency, low-value transactions.
Businesses use UPI for collections, vendor payments, reimbursements, and petty cash alternatives. Platforms like EnKash integrate UPI into spend and payout workflows, enabling businesses to manage UPI-based transactions alongside cards and other payment modes with full visibility and reconciliation.
