H1: Payment gateway checklist: 7 things that decide your revenue
Intro: Most comparisons stop at the MDR. These seven checks show what a gateway really costs you.
Alt: Checkout page on a phone with a payment being approved
You spent Rs.50,000 on Meta ads this weekend. Traffic poured in. 200 customers reached the checkout page. And then 40 of them failed to pay. Not because they changed their minds, but because your payment gateway timed out on the bank servers. You lost Rs.1.2 lakh in revenue.
The Rs.50K you spent on those ads? Gone either way.
You didn't lose that money to a bad ad. You lost it because you picked the wrong online payment gateway. And nobody warned you. Most guides won't tell you the truth about what actually matters when choosing a secure payment gateway in India. Whether you're running a D2C brand, SaaS company, or e-commerce business, selecting the right payment solutions provider directly impacts your customer experience, revenue, and business growth.
7 things that matter most when choosing a payment gateway:
- The real cost — look beyond the "2% MDR" sticker price
- Settlement speed — when your money actually hits your account
- Payment success rate — the hidden revenue killer
- Payment method coverage — especially UPI and recurring
- Integration & platform fit — can you actually ship this week?
- Support & reliability — who picks up the phone at 11 PM?
- Compliance & future-proofing — RBI rules, tokenization, and switching costs
1. The real cost: look beyond the "2% MDR" sticker price
Every payment gateway provider advertises "2% MDR." Nobody tells you that's just the starting point. Here's the math most online payment gateway blogs won't show you. At Rs.2 lakh GMV per month, a 2% MDR becomes 2.36% after 18% GST. But that's not the end of it.
Some payment gateway services charge:
- AMC
- Setup fees
- Per-refund fees
- Chargeback fees
These costs add up quickly. Chargebacks? Rs.500–Rs.2,500 per dispute, win or lose. International cards? Add another 1–2%.
If your business plans to accept international payments in India, receive payments from overseas customers, or work with an international payment gateway India, ask about cross-border pricing separately. Fees for cross border payments India or multi currency payment gateway India services may differ from domestic pricing. Click here to explore our cross-border payment solutions.
Want instant settlement? That's usually another 1.5–2%. Always model the full cost before signing up.
A gateway charging 1.7% with hidden fees and an 82% success rate can easily cost more than a secure payment gateway charging 2.0% with transparent pricing and a 90% payment success rate.
The difference between 93% and 82% success is worth real money at Rs.2 lakh GMV.
Smart tip
Ask for a written breakdown of all fees, not just the headline MDR. If they won't provide one, walk away.
DIY check
Before signing with any payment gateway provider, ask these five questions:
1. What's the all-in MDR after GST?
2. Are there any AMC or setup fees?
3. Is there a per-refund or per-chargeback fee?
4. What's the chargeback fee?
5. Is instant settlement charged separately?
2. Settlement speed: when your money actually hits your account
T+1 settlement is now the industry standard. Money from today's online payments lands in your account tomorrow.
That's a major improvement over the old T+2 cycle. However, not every payment gateway offers T+1 by default. Some still settle at T+2, while others charge an additional fee for faster settlements. Even with T+1, weekends and festival holidays can stretch settlement timelines. If you run a D2C business, money from Saturday's sales might not reach your account until Monday or Tuesday. During festive seasons like Diwali, delays may extend further.
A two-day delay on Rs.10 lakh in revenue is still a working capital challenge when inventory needs replenishment. Instant settlement sounds attractive, but it usually costs 1.5–2% of the settlement amount. At Rs.5 lakh/month, that's an additional Rs.7,500–Rs.10,000 in fees. Do the cash-flow math carefully.
Is the speed worth the premium? Or can your business comfortably operate with T+1? Most established online payment platforms now provide T+1 settlements by default, while a few continue to restrict them based on merchant volume. Understand the settlement policy before the festive shopping season begins.
3. Payment success rate: the hidden revenue killer
The gap between 93% and 82% payment success rates is not a "nice to have." It's a revenue killer.
At Rs.2 lakh GMV, that 11-point spread costs you roughly Rs.16,000–20,000 per month in lost sales. Not all failed transactions are recoverable, but even recovering half of them translates into Rs.8K–10K back into your business every month. For businesses relying on online payments, every percentage point improvement in payment success directly impacts revenue, customer satisfaction, and repeat purchases.
Transactions fail for several reasons in India:
- Bank downtime on Friday evenings
- Broken 3D Secure redirects on mobile devices
- Poor UPI payment Collect flows on certain browsers
- Network latency in Tier 2 and Tier 3 cities
Your customers in Indore don't always have the same internet stability as customers in Mumbai. Dynamic routing helps overcome many of these issues by automatically sending transactions to the best-performing acquiring bank in real time. However, not every payment gateway provider offers this capability.
Before selecting an e-commerce payment gateway, test your checkout under real-world conditions:
- Older Android devices
- Peak traffic hours
- Festival sales
- Slow 4G networks
If your secure payment gateway cannot handle a flash sale, you'll discover it the expensive way.
DIY check
Before signing up, perform a simple test. Run 10 transactions on a slow 4G connection at 8 PM on a Friday. If more than 2 transactions fail, continue evaluating other payment gateway services.
4. Payment method coverage (especially UPI and recurring)
Today, UPI payment accounts for more than 83% of digital transactions in India.
If your payment gateway treats UPI as an afterthought, you're leaving money on the table. A modern online payment gateway should support multiple payment methods while ensuring a seamless checkout experience across devices.
Not all UPI is equal. There is an important difference between UPI Intent and UPI Collect. UPI Intent (in-app flow) generally delivers higher payment success rates than UPI Collect (redirect flow). For mobile-first D2C brands, Intent should be the preferred experience.
If your checkout redirects customers to a third-party UPI application, expect higher abandonment rates. Choosing a UPI gateway that supports native Intent flows can significantly improve conversion rates.
Recurring payments matter for SaaS
If you're running a SaaS business, UPI Autopay is no longer optional. Card-based recurring payments are relatively mature in India. However, UPI mandate retry logic is still evolving. If your payment gateway services don't support automated UPI mandate recovery, subscription churn can increase significantly.
1. RuPay Credit on UPI
RuPay Credit on UPI is now available for eligible merchants. Ask whether your UPI gateway supports it. Customer adoption is growing steadily and can improve payment flexibility.
2. EMI & Buy Now Pay Later (BNPL)
For businesses selling electronics, furniture, fitness equipment, or premium lifestyle products, EMI and BNPL options often increase Average Order Value (AOV).
3. NACH & e-Mandates
These remain important for recurring SaaS subscriptions, especially for lower ticket-size payments. "100+ payment methods" is often just marketing. Instead, ask which payment methods are native, which are redirect-based, which are supported directly by the payment gateway, and which are dependent on third-party integrations.
A quick note for D2C brands
This section focuses primarily on your prepaid payment stack. If 30–50% of your orders are Cash on Delivery (COD), that's a separate optimization challenge. A poor checkout experience pushes more customers toward COD, increasing Return-to-Origin (RTO) rates. Improve your online payments, UPI payment, and checkout experience first. Then optimize COD.
If your business also operates offline, consider offering QR code payment and Scan to Pay options to create a seamless omnichannel payment experience. Solutions such as Scan to Pay Business Application and interoperable QR payments help merchants accept digital payments quickly while improving customer convenience.
5. Integration & platform fit: can you actually ship this week?
If you're launching a new business, this might be your number one priority. If you're switching providers, payment success rates, integration quality, and costs probably matter more.
Different businesses require different capabilities from their payment gateway:
- Solo founders often need a no-code onboarding journey.
- SaaS companies need clean APIs, SDKs, and reliable webhooks.
- D2C brands require robust plugins for Shopify, WooCommerce, Magento, and other ecommerce platforms.
A good ecommerce payment gateway should integrate easily with your existing technology stack while minimizing development effort.
Shopify users should factor in additional costs
Shopify India charges an additional 2% fee because Shopify Payments is currently unavailable in India. Many founders discover this hidden cost only after launching. When evaluating payment gateway providers, include platform-specific charges in your calculations and not just MDR.
Merchant onboarding & KYC
KYC timelines vary across providers. Most established payment gateway services complete merchant verification within 2–5 business days. The RBI's latest Payment Aggregator Directions require Customer Due Diligence (CDD) for all merchants, making compliance more important than ever.
Some providers advertise "instant onboarding." In reality, proper verification takes time. If your business documentation isn't complete, delays are inevitable regardless of the provider. Most onboarding delays happen because:
- Business and bank addresses don't match
- GST information is incomplete
- Utility bills are outdated
- Businesses operate from shared workspaces without adequate documentation
Prepare your documents before applying. The businesses that go live fastest aren't necessarily the ones choosing the fastest online payment platform. They're the ones who prepare thoroughly.
Always test the sandbox environment before signing a contract. Look for:
- Updated API documentation
- Reliable SDKs
- Active developer support
- Plugin maintenance
- Smooth reconciliation
If the documentation is outdated or plugins haven't been updated in months, consider it a warning sign. A reliable payment gateway should make integration simple and not become another development project.
6. Support & reliability: who picks up the phone at 11 PM?
Every payment gateway provider claims to offer 24/7 support. Founder forums and merchant reviews often tell a different story. A 48-hour ticket turnaround during a live sale isn't just an inconvenience — it's lost revenue, frustrated customers, and missed business opportunities.
When evaluating payment gateway services or online payment platforms, don't just compare pricing. Assess the quality of merchant support, technical assistance, and operational reliability. Before choosing a payment gateway, ask these questions:
1. Is there a phone number that connects you to a real person?
2. What's the escalation matrix if the first support agent can't resolve your issue?
3. Will you have a dedicated account manager, or will you be part of a general merchant support queue?
4. What happens if your online payment gateway experiences downtime during a flash sale or festive shopping period?
Support responsiveness matters just as much as transaction success rates. An issue resolved in 15 minutes can save thousands of rupees in lost sales. The same issue left unresolved for several hours can significantly impact customer trust and business continuity.
Reliability matters more than marketing claims.
Most providers advertise 99.9% uptime. On paper, that sounds excellent. In reality, 99.9% uptime still allows for nearly 8.7 hours of downtime every year.
If even a few of those hours occur during Diwali, a major product launch, or your highest-selling weekend, the financial impact can be substantial. Instead of relying solely on marketing claims, ask prospective payment gateway providers for:
- Historical uptime reports
- Scheduled maintenance policies
- Disaster recovery plans
- Incident response timelines
- Average resolution time for critical issues
Better yet, test the support experience yourself. Call the support number at 10 PM on a Saturday and see how quickly someone responds.
A provider's support experience before you become a customer often reflects the level of support you'll receive afterward.
7. Compliance & future-proofing: RBI rules, tokenization, and switching costs
Choosing the right payment gateway isn't only about today's requirements. It's also about ensuring your business remains compliant as regulations evolve. A reliable payment solutions partner should help your business stay ahead of changing RBI guidelines while supporting future growth.
RBI compliance matters
The RBI's latest Payment Aggregator Directions have changed the compliance landscape. All merchants must now undergo Customer Due Diligence (CDD). Small merchants with turnover below Rs.40 lakh benefit from simplified KYC requirements, but PAN verification, business verification, and physical verification still remain essential.
If your payment gateway provider fails to comply with RBI regulations, settlement delays and regulatory action can directly affect your business. Choosing a trusted RBI authorised payment aggregator with strong compliance processes reduces operational risk and ensures uninterrupted online payments.
Tokenization: think long-term
Tokenization is another area many businesses underestimate. Under RBI guidelines, raw card data cannot be stored. If you decide to migrate to another online payment gateway in the future, your customers may need to re-register their saved cards.
For SaaS companies, this means collecting recurring payment mandates again. For D2C brands, it may lead to increased cart abandonment as returning customers are required to re-enter payment details. The switching cost is often much higher than merchants anticipate. Selecting the right secure payment gateway from the beginning helps avoid unnecessary migration challenges later.
Also check
1. GST-compliant invoicing: Automatically generated GST invoices are essential for B2B SaaS businesses and growing enterprises. Ensure your payment gateway services integrate smoothly with your accounting and reconciliation workflows.
2. TDS on software services: If your business pays more than Rs.30,000 annually to software vendors including your payment gateway provider, consult your Chartered Accountant to determine whether Section 194J or Section 194C applies. A quick consultation today is significantly less expensive than resolving a tax notice later.
3. Cross-border PA-CB: If you plan to bill US/EU customers, you need a separate framework. Explore further.
The 6-week rule
Before peak shopping seasons like Diwali, don't wait until the last minute. Test your:
- Payment gateway
- Settlement flow
- Refund journey
- UPI payment experience
- Checkout performance
- Customer notifications
At least six weeks before your biggest sales event — not six days. This provides enough time to identify issues, complete integrations, and resolve operational bottlenecks before customer traffic increases.
Choose a payment partner that grows with you
Your business will evolve. Your payment partner should evolve with it. Whether you're expanding from domestic online payments to cross border payments India, adding UPI payment, enabling QR code payment, or introducing recurring billing, your payment gateway should support every stage of growth without requiring frequent migrations.
Choose a provider that offers scalable digital payment services, robust merchant support, regulatory compliance, and the flexibility to grow alongside your business.
The decision scorecard: rate any payment gateway in 5 minutes
Choosing the right payment gateway is a strategic business decision — not just a pricing comparison. Use this practical checklist before signing with any payment gateway provider. Score each provider as Poor, Okay, or Good across every category to identify the online payment gateway that best fits your business needs today and supports your growth tomorrow.
| # | What to check? | Why it matters? | Your score |
|---|---|---|---|
| 1. | Total cost — MDR + GST + AMC + setup + refund + chargeback + instant settlement fees | The advertised MDR rarely tells the full story. Model at least three months of actual transaction costs before choosing a payment gateway. | |
| 2. | Settlement speed — T+1 (standard) vs T+2 vs instant, and the cost of instant | Faster settlements improve cash flow and working capital, helping businesses restock inventory and manage operations efficiently. | |
| 3. | Success rate — UPI Intent vs Collect, dynamic routing, mobile checkout performance | An 11-point gap at Rs.2 L GMV costs ~Rs.16K–20K/month. | |
| 4. | Payment methods — UPI Intent, Autopay, RuPay credit, EMI/BNPL, NACH | A comprehensive payment solutions provider should support the payment methods your customers actually use — not just advertise large numbers. | |
| 5. | Integration & platform fit — No-code options, Shopify plugin, API quality, sandbox, KYC timeline | Does the timeline match your launch plan? Prepare paperwork early to avoid delays. | |
| 6. | Support quality — Phone, chat, escalation matrix, dedicated AM, real response times | Fast, knowledgeable support minimizes downtime and protects revenue during peak business periods. | |
| 7. | Compliance & future-proofing — RBI PA Directions, tokenization, GST invoicing, cross-border | Selecting a compliant payment gateway provider today reduces future migration costs and supports business expansion. |
Quick evaluation tip
If a provider scores "Poor" on more than two of these parameters, continue evaluating other options. A secure payment gateway should perform consistently across all seven areas — not just excel in pricing.
Your payment gateway should work quietly in the background. Your customers should never have to think about it. Neither should you.
The best online payment gateway is one that enables smooth online payments, delivers consistently high success rates, settles funds on time, supports your preferred payment methods, complies with RBI regulations, and scales alongside your business.
