The top payment processing companies are 1. Stripe, 2. Xflow, 3. PayPal, 4. Adyen, 5. Razorpay, 6. Square, 7. PayU, 8. Fiserv, 9. Pine Labs and 10. Global Payments. Each one moves card, bank and wallet payments between customers, businesses and banks, but they differ on where they operate, who they serve and what they charge.

A payment processing company handles the steps between a customer paying and a business receiving the money: passing the payment details to the card network or bank, getting it approved and settling the funds.

1. Stripe

Stripe is the payment processing company most online businesses and software platforms build on. It handles cards, wallets and bank payments through one API in dozens of countries, and processed $1.9 trillion in total payment volume in 2025, up 34% on the year before.

Key features

• One API for many countries: accept cards, wallets and local methods in 135+ currencies without separate contracts in each market.
• Billing and invoicing: subscriptions, usage-based pricing and invoices run on the same platform.
• Connect for platforms: marketplaces and SaaS platforms can onboard users and pay them out.
• Fraud tools: machine-learning risk checks on every payment, included in the standard price.

Pros

• Developer tools and documentation are among the best in the industry, which shortens build time.
• Published, flat pricing in most countries.

Cons

• In India, new businesses join by invitation, international cards cost 3% plus 2% for conversion, and each dispute carries a ₹1,000 fee.
• Large or high-risk merchants can face account reviews and holds.

Best for: Online businesses, SaaS companies and platforms selling in several countries.

Verdict: The default choice for building payments into a product. Indian businesses should check access first and compare costs with Razorpay for domestic sales.

2. Xflow

Xflow is the cross-border pick in this list. It is not a card processor; it is a cross-border payments platform that lets Indian businesses and freelancers collect payments from clients abroad. Clients pay into local account details in 25+ currencies, Xflow converts at the live mid-market rate and settles rupees to the Indian bank account the next business day, with an eFIRA for every payment.

Key features

• Receiving accounts in 25+ currencies: clients pay by local bank transfer, which avoids the fees deducted along a SWIFT wire.
• Published flat fees: $12 up to $2,000 on Starter or $20 up to $5,000 on Growth, so you know the cost before you invoice.
• eFIRA for every payment: the proof of foreign payment needed to treat services as a zero-rated export under GST.
• RBI authorisation: final authorisation as a cross-border payment aggregator for inward and outward payments.

Pros

• Far cheaper than card processing for large B2B invoices from abroad.
• Next-business-day settlement keeps exporters' cash flow predictable.

Cons

• It does not process domestic cards or UPI, so Indian businesses still need a gateway such as Razorpay for local sales.
• Pricing above $10,000 per payment is quoted, not published.

Best for: Indian exporters, agencies, SaaS companies and freelancers paid by clients abroad.

Verdict: For the cross-border part of payment processing, Xflow is the strongest choice for Indian businesses; pair it with an Indian gateway for domestic customers.

3. PayPal

PayPal is the world's best-known digital wallet and checkout, processing $1.79 trillion in total payment volume in 2025. Customers can pay with a PayPal balance, card or linked bank account, which makes it a trusted option for international buyers.

Key features

• PayPal checkout: one-click payments for hundreds of millions of account holders.
• Cards and local methods: accept cards even from customers without a PayPal account.
• Buyer and seller protection: dispute handling built into every transaction.

Pros

• Instant trust with international customers, which can lift conversion on first purchases.
• Fast to set up with payment links and invoices.

Cons

• International payments into India cost 4.4% plus a fixed fee, and conversion adds about 3% above PayPal's base rate.
• Conversion at PayPal's own rate rather than the mid-market rate.

Best for: Online sellers whose customers abroad prefer to pay through PayPal.

Verdict: Worth offering where customers expect it, but expensive as the main way to collect large international payments into India.

4. Adyen

Adyen is an enterprise payment processing company used by large global brands to handle online, in-store and mobile payments on a single platform. It processed about €1.4 trillion in 2025, and acts as its own acquirer in many markets.

• Unified commerce: one platform and one data view across online, in-store and mobile.
• Local methods worldwide: cards plus local wallets and bank methods in many countries.
• Adyen for Platforms: onboarding and payouts for marketplaces.
• Data-driven authorisation: optimisation tools that raise approval rates.

Pros

• Interchange++ pricing shows exactly what card networks charge and what Adyen adds.
• Strong fit for multi-country retailers and marketplaces.

Cons

• Built for enterprises; smaller businesses may not meet its onboarding bar.
• Integration effort is significant.

Best for: Global enterprises and marketplaces with high volumes across many countries.

Verdict: The enterprise standard for unified global payments; more platform than a small or mid-sized business needs.

5. Razorpay

Razorpay is India's best-known online payment processing company, with a checkout that accepts UPI, cards, net banking and wallets. It holds RBI authorisation as a payment aggregator and charges 2% plus GST per transaction with no set-up fee.

• RazorpayX: business banking, payouts and vendor payments alongside collections.
• International cards: accept cards from abroad for registered, fully activated merchants.

Pros

Cons

• UPI carries zero MDR by law, but a 2% platform fee applies at Razorpay.
• International card payments cost more than domestic ones.

Best for: Indian online businesses that want a complete domestic checkout and payouts.

Verdict: The default payment processor for Indian online businesses; compare UPI fees if most of your customers pay by UPI.

6. Square

Square is a payment processing company built around simple card readers and point-of-sale software for shops, cafés and restaurants, with online checkout and invoices on the same account. On the US Free plan, in-person card payments cost 2.6% plus 15 cents and online payments 3.3% plus 30 cents; Square is not available in India.

8. Fiserv

Fiserv is one of the largest payment technology companies in the world, providing card acquiring and processing for banks and merchants and the Clover point-of-sale system, which serves about 910,000 merchants.

• Bank technology: core processing and card issuing services for financial institutions.

Pros

• Enormous scale and reliability.
• Clover gives small merchants a full point-of-sale system.

• Pricing is custom and often sold through banks, so it is harder to compare.
• Clover is not available in India, so Indian merchants deal with Fiserv only through its acquiring business and banks.

Best for: Banks and large or multi-location merchants, and small businesses using Clover.

Verdict: A heavyweight processor behind many banks and merchants; most small businesses meet it through Clover or their bank.

9. Pine Labs

Pine Labs is India's leading in-store payment processing company, best known for its card machines in shops and malls, and also offers online payments. It served about 9.9 lakh merchants as of June 2025 and listed on Indian stock exchanges in November 2025.

Pros

Best for: Indian retailers, brands and chains taking payments in store.

Verdict: The go-to processor for in-store payments in Indian retail; online-only businesses will find a gateway such as Razorpay simpler.

10. Global Payments

Global Payments is one of the world's largest payment processors. It completed its purchase of Worldpay on 12 January 2026, creating a business that serves more than 6 million merchant locations and handles about $3.7 trillion in payment volume a year across 175+ countries. On the same day it sold its card-issuing business to FIS, so it now focuses on merchants.

Key features

• Merchant acquiring at global scale: card processing for small businesses to large enterprises.
• Worldpay's e-commerce platform: online processing for global merchants.
• Software partnerships: payments embedded in vertical software for many industries.

Pros

• One of the largest processing networks after the Worldpay merger.
• Covers both in-store and online payments.

Cons

• The merger is recent, so products and contracts are still being combined.
• Pricing is custom and aimed at larger merchants.

Best for: Large and mid-sized merchants that want a processor with global reach.

Verdict: A global heavyweight after the Worldpay deal; best suited to larger merchants with negotiating power.

A card payment passes through four parties in about two seconds: the payment processor sends the card details to the card network, the network asks the customer's bank (the issuer) to approve, and the merchant's bank (the acquirer) settles the money, usually the next working day. The merchant pays for this as the merchant discount rate (MDR), which is split three ways.

India's rules change the maths: UPI and RuPay debit card payments to merchants carry zero MDR by law since 1 January 2020, so processors earn little or nothing from them and some add a platform fee instead. RBI also caps MDR on other debit cards at 0.40% (up to ₹200) for small merchants with turnover up to ₹20 lakh and 0.90% (up to ₹1,000) for larger ones. Credit and international cards have no cap, which is why they cost merchants 2% to 3% or more.

UPI itself is run by the National Payments Corporation of India (NPCI), which processed 24.07 billion UPI transactions worth ₹29.37 lakh crore in September 2026. NPCI is the network, not a processor you sign up with: businesses accept UPI through a payment aggregator or bank.

These terms overlap, but each describes a different job in the payment chain.

Many companies in this list play more than one role: Razorpay, for example, is a gateway and an aggregator. For a deeper explanation, see our guide on what a payment processor does.

Yes, but in India you need RBI authorisation as a payment aggregator if you will collect and settle money for other merchants. Under RBI's payment aggregator directions of September 2025, a non-bank applicant needs a net worth of ₹15 crore when it applies and ₹25 crore by the end of the third financial year. Most new entrants therefore start as resellers or white-label partners and apply for a licence once they have scale.

Choose by where your customers are and how they pay, then compare the total cost on your typical transaction, including GST on fees and any conversion margin.
