You've built your online store, your product's ready, and customers are showing interest. But here's the thing that'll make or break your sales: how you collect payments. Pick the wrong payment gateway and you'll lose customers at checkout, deal with delayed settlements, and pay more in fees than you should.
I've integrated payment gateways into dozens of e-commerce projects across India. I've dealt with Razorpay support tickets at midnight, debugged Cashfree webhooks, and helped clients migrate away from gateways that charged hidden fees. This guide is based on that real-world experience — not just spec-sheet comparisons.
By the end, you'll know exactly which payment gateway fits your business, how much you'll actually pay, and the gotchas nobody mentions in the marketing pages.
Razorpay is the best all-rounder for most Indian businesses (2% + GST, 100+ methods, great API). Cashfree wins on pricing (1.6%) and speed (instant settlements). Instamojo is perfect for beginners with no website. PayU suits larger businesses needing credit solutions.
- All major gateways charge 0 setup fees — you only pay per transaction
- Domestic transaction fees range from 1.6% to 2% + GST across providers
- UPI dominates India with 75%+ of all digital payments — your gateway must handle it well
- Settlement speed varies wildly: instant (Cashfree) to 3 days (Instamojo)
- International payment support adds 3–3.5% fees but opens global revenue
- Reading time: 14 minutes

Razorpay: The All-Rounder
If you've talked to any Indian developer about payments, they've mentioned Razorpay. There's a reason it's the default recommendation — it genuinely does most things well.
Why Developers Love It
Razorpay's API documentation is excellent. Clean, well-organized, with code samples in every major language. Their test mode lets you simulate every payment scenario without touching real money. For a developer integrating payments into a custom-built website, Razorpay is the path of least resistance.
What You Actually Pay
The headline rate is 2% + GST (effectively ~2.36%) on every domestic transaction. International cards bump to 3% + GST. There's no setup fee, no AMC, and no hidden charges. You pay only when you get paid.
For high-volume businesses (₹10 lakh+/month in transactions), Razorpay offers custom pricing. I've seen rates as low as 1.7% for clients processing large volumes consistently.
Where It Falls Short
Customer support can be slow for smaller accounts. If you're processing ₹50,000/month, don't expect white-glove treatment. Their dashboard, while powerful, can feel overwhelming for non-technical users. And the 2% UPI rate stings when competitors charge as low as 0.40%.
Cashfree: The Price Fighter
Cashfree doesn't get the same hype as Razorpay, but it probably should. They're quietly becoming the smart choice for cost-conscious businesses.
The Pricing Advantage
At 1.6% + GST for new merchants (through March 2026), Cashfree undercuts everyone. Their UPI rate of 0.40% is remarkable when you consider that UPI makes up the majority of digital payments in India. If your customers mostly pay via UPI — and in India, they probably do — the savings add up fast.
Instant Settlements
This is Cashfree's killer feature. While Razorpay settles in T+1 and PayU takes T+2, Cashfree can put money in your account within 15 minutes. For businesses with thin margins or high inventory costs, that cash flow speed is worth its weight in gold.
Where It Falls Short
The ecosystem isn't as mature as Razorpay's. Fewer ready-made plugins for popular platforms, slightly less comprehensive documentation, and a smaller developer community. If you're building something custom and hit a weird edge case, finding help online is harder.
PayU: The Enterprise Pick
PayU has been around longer than most competitors and processes billions of dollars annually. It's the choice for businesses that prioritize stability and credit solutions over flashy features.
Credit Solutions
PayU's standout feature is its lending arm. They offer working capital loans to merchants based on transaction history. If you need capital to scale inventory before a big season, PayU can fund you directly — no bank applications, no collateral discussions.
Where It Falls Short
The dashboard feels dated compared to Razorpay and Cashfree. Settlement at T+2 days is slower than competitors. And unless you're processing significant volume, you won't get much attention from their support team. The integration experience is also less polished — their developer docs could use a refresh.
Instamojo: The Beginner's Best Friend
Instamojo isn't really competing with Razorpay at the API level. It's playing a completely different game — making payments accessible to people who don't have technical skills or even a website.
No Website? No Problem
You can create a payment link in 30 seconds and share it on WhatsApp. That's Instamojo's superpower. No coding, no integration, no developer needed. It also offers a free online store builder — good enough for someone selling 10–50 products without needing a custom e-commerce platform.
Where It Falls Short
The 2% + ₹3 flat fee per transaction adds up, especially on small transactions. Settling in 3 business days is the slowest of the bunch. Limited payment method support means you can't accept as many payment options. And if you outgrow Instamojo, migrating to something more robust takes effort.
How to Choose the Right Payment Gateway
Don't pick a gateway based on brand recognition alone. Ask yourself these questions:
- What do your customers prefer? If 80% of your orders come through UPI, Cashfree's 0.40% UPI rate saves you serious money vs. Razorpay's 2%.
- How fast do you need the money? If you're buying inventory daily, T+3 settlement (Instamojo) could hurt your cash flow. Cashfree's instant settlement changes the game.
- Do you sell internationally? If you have overseas customers, Razorpay and PayU handle multi-currency better than Instamojo.
- How technical is your team? No developer? Instamojo. Have a dev team? Razorpay or Cashfree's APIs are superior.
- What's your monthly volume? Below ₹1 lakh/month, the fee differences are tiny. Above ₹10 lakh/month, negotiate custom rates with any gateway.
Hidden Costs Nobody Mentions
The TDR percentage is the obvious cost. Here's what catches people off guard:
- GST on fees: That 2% TDR becomes ~2.36% after 18% GST. Every gateway in India charges GST on top of transaction fees. Budget accordingly.
- Refund processing: Most gateways don't refund their fee when you refund a customer. You ate the transaction cost and the customer gets a full refund. Some gateways charge a separate refund processing fee too.
- Chargeback fees: If a customer disputes a charge with their bank, you could pay ₹200–₹500 per chargeback on top of losing the transaction amount.
- Instant settlement surcharge: Some gateways charge 0.5–1% extra for same-day or instant settlement. Always check if "instant" has a premium.
- International payment KYC: Accepting foreign currency requires FIRA compliance, additional documentation, and sometimes separate merchant accounts. The process takes 2–4 weeks.
Integration: What to Expect
Here's a realistic timeline for implementing a payment gateway on your website:
The Simple Route (1–2 days)
If you're using Shopify, WooCommerce, or another popular platform, most gateways offer ready-made plugins. Install the plugin, enter your API keys, test with sandbox mode, and go live. A competent developer can do this in a few hours.
Custom Integration (3–7 days)
For custom-built websites, you'll use the gateway's API directly. This involves setting up webhooks for payment confirmation, handling edge cases (failed payments, partial refunds, network timeouts), and building a proper checkout flow. Budget 3–5 days for a clean implementation, plus 2 days for testing.
Don't Skip Testing
Every gateway offers a sandbox/test mode. Use it. Simulate successful payments, failed payments, refunds, and edge cases before going live. I've seen businesses lose their first 50 orders because their webhook handler had a bug that nobody caught in testing.
Frequently Asked Questions
Cashfree currently offers the lowest rates at 1.6% for new merchants. Their UPI rate of 0.40% is the best in the market. Paytm charges 1.99%. Razorpay and PayU both charge 2%. For high volumes, all gateways offer custom pricing.
Not always. Instamojo lets you accept payments without GST registration — ideal for freelancers. Razorpay and Cashfree work with sole proprietorships. PayU typically needs a registered business entity. Check each gateway's KYC requirements.
Cashfree offers instant settlements within 15 minutes. Razorpay settles in T+1 day. PayU takes T+2 days. Instamojo settles in about 3 business days. Faster options may cost extra.
Yes. Razorpay supports 92 currencies, PayU handles 100+, and Cashfree also supports international payments. Fees are higher (3–3.5% + GST) and you'll need additional KYC documentation. Instamojo has limited international support.
Razorpay is the best all-rounder. If you're a freelancer or micro-seller with no website, Instamojo's simplicity wins. If fast cash flow matters most, Cashfree's instant settlements are unbeatable.
Razorpay has better developer tools, a more modern dashboard, and a larger community. PayU offers stronger credit solutions for SMEs. For most startups and growing businesses, Razorpay edges ahead on developer experience and ecosystem.
TDR (Transaction Discount Rate) is the percentage fee on each transaction. In India, typical TDR ranges from 1.6% to 2% for domestic payments and 3–3.5% for international cards. It's the main cost of using a payment gateway.
No gateway is completely free — they all charge per-transaction fees. But most major gateways have zero setup fees and zero AMC. You only pay when you process a transaction, which is actually fair.
Pick Your Gateway and Start Selling
Here's the bottom line. For most Indian businesses in 2026, Razorpay is the safest choice — great API, reliable, and widely supported. If you're cost-sensitive and UPI-heavy, Cashfree saves you real money. If you need payments without a website, Instamojo gets you started in minutes. And if you're an enterprise wanting credit solutions, PayU has your back.
Don't overthink it. Pick the one that matches your current needs, sign up (it's free), and start collecting payments. You can always switch later — the migration effort is manageable.
