UPI Gateway: How It Works and What Businesses Need to Know (2026)
April 1, 2026
Quick Answer: A UPI gateway is a payment processing interface that enables businesses to accept payments via India's Unified Payments Interface (UPI) network. For businesses in Singapore, Malaysia, and the Philippines, accepting UPI payments has become increasingly relevant as Indian tourist and expatriate spending grows. HitPay supports UPI QR-based payments, allowing merchant partners to capture this high-value payment segment without additional integration complexity.
India's Unified Payments Interface has become one of the world's most adopted real-time payment systems, processing over 16 billion transactions monthly across 450 million users. If you're also exploring broader payment gateway options for Singapore, HitPay supports UPI alongside 50+ other payment methods from a single platform. As Indian travelers, students, and professionals move across Southeast Asia in growing numbers, the demand for UPI-compatible point-of-sale and online checkout experiences has followed. This guide explains what a UPI gateway is, how it works, and why businesses in Singapore and the broader region should take it seriously in 2026.
What Is a UPI Gateway?
A UPI gateway is the technical infrastructure that connects a merchant's checkout — whether physical or online — to India's Unified Payments Interface network. UPI itself is a real-time interbank payment protocol developed by the National Payments Corporation of India (NPCI). It allows users to send and receive money directly from their bank accounts using a Virtual Payment Address (VPA) or a QR code, without needing to enter card details.
When a UPI gateway is integrated into a payment solution, it generates a dynamic QR code or UPI deep link at checkout. The customer scans this with any UPI-enabled app — such as PhonePe, Google Pay India, or Paytm — and approves the payment from their Indian bank account. Settlement flows through the gateway back to the business.
For Southeast Asian businesses, a UPI gateway is the bridge between local checkout infrastructure and Indian consumers' preferred payment method.
How Does a UPI Gateway Work for Overseas Businesses?
The cross-border UPI payment flow involves a few more layers than domestic Indian transactions, but the customer experience remains simple:
QR Code Generation — The payment gateway generates a UPI-compatible QR code tied to the transaction amount and business details.
Customer Scan and Approval — The Indian customer opens their UPI app, scans the QR code, and authorises the payment using their UPI PIN.
Real-Time Confirmation — The UPI network processes the payment in real time. A success confirmation is sent to both the customer and the business.
Currency Conversion and Settlement — For cross-border UPI transactions, the gateway handles the currency conversion (INR to SGD, MYR, or PHP) and settles funds to the business's local account according to HitPay's standard settlement schedule.
The entire customer-facing interaction typically takes under 30 seconds. There is no card, no foreign transaction fee on the customer's end, and no need for the customer to carry cash or a travel card.
Why Accepting UPI Gateway Payments Matters in Southeast Asia
The Indian Traveller and Resident Market Is Growing
Singapore welcomed 1.2 million Indian tourists in 2024, with that number continuing to grow. Malaysia and the Philippines also see substantial inbound Indian traffic, both for leisure and for business travel. UPI has an exceptionally high adoption rate among Indian consumers — with over 16 billion transactions processed monthly across 450 million users. As of early 2025, over 9,000 merchants in Singapore had already enabled UPI. Businesses that do not offer a UPI payment option risk losing a segment of high-spending visitors who prefer — and often expect — to pay via UPI.
UPI Gateway Payments Reduce Friction at Checkout
International card payments from Indian-issued cards frequently encounter foreign transaction blocks, currency confusion, or declined authorisations. UPI eliminates these friction points entirely. The customer pays in Indian rupees from their home bank account. The gateway handles everything else. For retail, F&B, hospitality, and services businesses in Southeast Asia, this translates directly to fewer abandoned transactions and improved customer satisfaction.
HitPay Supports UPI QR Payments for Singapore Merchant Partners
HitPay partnered with NPCI International in March 2025 to bring UPI acceptance to Singapore merchants. HitPay merchant partners in Singapore can accept UPI payments through the HitPay point-of-sale system and payment links, without needing a separate integration or an Indian acquiring bank relationship. This makes UPI gateway acceptance accessible to small and medium-sized businesses — not just large hospitality chains. Merchant partners can save up to 50% on payment processing fees compared to traditional card schemes by accepting UPI.
How to Accept UPI Payments Through HitPay
Setting up UPI gateway acceptance with HitPay is straightforward for existing merchant partners:
In-Person (POS): HitPay's POS app generates a dynamic UPI QR code for each transaction. The customer scans and pays. No additional hardware is required.
Online Checkout: HitPay's hosted payment page includes UPI as a selectable payment method alongside cards, PayNow, and other local options.
Payment Links: Merchant partners can send UPI-enabled payment links via SMS, WhatsApp, or email — useful for service businesses and remote transactions.
There is no need to manage separate merchant accounts or reconcile multiple settlement reports. UPI transactions appear alongside all other payment methods in the HitPay dashboard.

Frequently Asked Questions
Q: What is a UPI gateway and how is it different from a regular payment gateway?
A UPI gateway is specifically designed to process payments routed through India's Unified Payments Interface network. A standard payment gateway typically handles card networks (Visa, Mastercard) or local schemes. The key difference is the payment rail: UPI transactions originate from Indian bank accounts via QR codes or VPAs, rather than from card credentials.
Q: Can businesses in Singapore accept UPI gateway payments?
Yes. Businesses in Singapore can accept UPI payments through payment solutions that support cross-border UPI integration, such as HitPay. The setup does not require a business to have an Indian bank account or an Indian acquiring relationship. HitPay handles the currency conversion and settles funds in Singapore dollars.
Q: Is a UPI gateway secure for business use?
UPI is built on two-factor authentication — the customer must have their registered mobile device and enter a UPI PIN to authorise any payment. This makes UPI transactions highly secure. For businesses, the payment confirmation is real-time and irreversible once approved, reducing the risk of chargebacks that are common with card payments.
Q: What fees are involved in accepting UPI gateway payments?
HitPay charges a 2% transaction fee for UPI payments, with no setup fees or monthly subscription required. You only pay when you collect. See the full HitPay pricing page for current rates across all payment methods.
Q: Which UPI apps are compatible with a UPI gateway for overseas transactions?
Most major UPI apps with cross-border payment capability are compatible, including PhonePe, Google Pay India, and Paytm. HitPay's UPI QR codes are compatible with the major apps used by Indian travellers, with support for over 50 UPI-enabled apps in total.
Q: Does HitPay support UPI gateway payments for online stores?
Yes. HitPay merchant partners operating online stores — including those on Shopify, WooCommerce, or HitPay's native checkout — can enable UPI as a payment method on their checkout page. Indian customers will see UPI as a selectable option alongside other available payment methods.
For businesses in Singapore serving Indian visitors, residents, or B2B clients, UPI gateway acceptance is no longer a niche feature — it is an expected part of a complete payment offering. HitPay gives merchant partners the ability to enable UPI payments across in-person, online, and link-based channels from a single dashboard.
