7 Cheapest Payment Gateways in India for SaaS Startups in 2026
Most SaaS founders in India make the same mistake when choosing a payment gateway: they open a tab, compare the MDR percentages, and pick the lowest number. It feels like a rational, cost-conscious decision. It usually isn’t.
The payment gateway with the lowest headline rate can, and often does, end up costing you significantly more. What you lose to failed payments, hidden annual maintenance charges (AMC), slow settlements, and poor infrastructure rarely shows up in any pricing comparison table. A payment gateway that’s 0.4% cheaper on paper can quietly cost you lakhs every month in revenue that was already within reach.
The right question isn’t: “Which payment gateway has the lowest transaction rate?”
The right question is: “Which payment gateway puts the most money in my bank after all fees, failures, and friction?”
That’s the framework this article is built on.
The 5-Bucket Total Cost Model
Before jumping to the payment gateways, here’s the lens you should use to evaluate every option:
- Direct fees: Instrument-wise TDR/MDR + 18% GST (often forgotten)
- Fixed fees: Setup cost, AMC, minimum monthly commitments
- Failure cost: Revenue lost to payment failures; the biggest hidden line item. If 8% of 10,000 payment attempts fail at ₹1,200 AOV, that’s ₹9.6 Lakhs of potential revenue never realised
- Ops cost: Reconciliation complexity, refund tracking, dispute workflows, finance team overhead
- Cash-flow cost: T+1 vs T+3 settlement differences that lock up your working capital
A payment gateway at 1.7% with 5,000 AMC and 75% success rate will consistently lose to a payment gateway at 2.0% with zero AMC and 90% success rate, especially for SaaS startups where every renewal attempt and recurring charge matters.
How to Read the Ratings
Each payment gateway is rated on 5 parameters (out of 5 ⭐):
- True Cost (not just MDR): Accounts for AMC, setup fees, and effective rate
- SaaS/Subscription Fit: Recurring billing, retries, dunning
- Ease of Integration: Developer docs, onboarding speed
- International Support: Cross-border payments
- Reliability & Success Rate: Uptime, routing, customer support
1. Razorpay Payment Gateway
The highest-ROI payment gateway for SaaS startups, not the cheapest headline rate, but the most money in your bank. Razorpay’s 2% standard rate looks more expensive than some competitors at 1.7–1.8%. That’s the exact comparison trap this article is built to dismantle.
Pricing
| Payment Method | Fee |
| Domestic Cards (Visa/MC/Maestro) | 2% + 18% GST |
| UPI | ₹0 MDR, 2% Platform Fee |
| Net Banking (58+ banks) | 2% Platform Fee |
| Wallets | 2% Platform Fee |
| EMI / Cardless EMI | 3% Platform Fee |
| International Cards | 3% Platform Fee |
| Subscriptions (recurring) | +0.99% per transaction |
| Setup Fee | ₹0 |
| Annual Maintenance Charge (AMC) | ₹0 |
Why the “Expensive” Label Is Wrong
A payment gateway charging ₹10,000 AMC adds +0.16% to their effective rate at ₹5L/month volume, pushing their “cheap 1.8%” to a real 1.96%. Suddenly, Razorpay’s 2% is virtually identical in direct cost, but with far better infrastructure underneath.
Here’s where it stops being close: payment success rates. Budget payment gateways often deliver 70–75% success rates due to under-investment in routing infrastructure. Razorpay’s Smart Routing uses AI/ML to dynamically route each transaction through the highest-performing bank terminal in real time.
The math at ₹5L/month attempted GMV:
| Budget payment Gateway (70% SR) | Razorpay (90% SR) | |
| Revenue Captured | ₹3,50,000 | ₹4,50,000 |
| Transaction Fee | -₹6,300 (1.8%) | -₹9,000 (2.0%) |
| AMC (monthly) | -₹833 | ₹0 |
| Net Cash in Bank | ₹3,42,867 | ₹4,41,000 |
| Difference | — | +₹98,133/month |
You pay ₹2,700 more in fees. You capture ₹98,000 more in revenue. That’s a 36x return on the fee “premium.”
For SaaS specifically, Razorpay has a dedicated Subscriptions API for managing recurring billing, with international payment gateway offering, automatic retries, prorated upgrades, and dunning, all natively built-in, at no extra platform cost.
⭐ Ratings
| Parameter | Rating |
| True Cost (not just MDR) | ⭐⭐⭐⭐⭐ (5/5), Zero AMC eliminates hidden cost advantage of cheaper payment gateways, Zero MDR on UPI. |
| SaaS/Subscription Fit | ⭐⭐⭐⭐⭐ (5/5) |
| Ease of Integration | ⭐⭐⭐⭐⭐ (5/5) |
| International Support | ⭐⭐⭐⭐ (4/5) |
| Reliability & Success Rate | ⭐⭐⭐⭐⭐ (5/5) |
| Overall | ⭐ 4.8 / 5 |
Best for: Early-stage to growth-stage SaaS startups that want the highest net revenue, not just the lowest percentage fee, enterprise level SaaS startups who need success rate optimization at scale.
2. Atom Paynet (by NTT DATA)
Cheaper headline rate, but fixed charges quietly erode the advantage. Atom Paynet has been in the Indian market since 2006 with a 1.99% domestic card rate, slightly lower than Razorpay’s 2% on paper. But that comparison breaks down the moment you factor in the mandatory one-time integration fee (₹1,955) and annual software upgrade charge (₹2,955).
Pricing
| Payment Method | Fee |
| Credit Cards (Domestic) | 1.99% + ₹3 |
| Debit Cards ≤₹2,000 | Free, 1-2% Platform Fee |
| Debit Cards >₹2,000 | 1% |
| Net Banking | 1.99% + ₹3 |
| e-Wallets | 2.2% |
| International Cards / Amex / Diners | 3.95% |
| One-time Integration Fee | ₹1,955 |
| Annual Software Upgrade | ₹2,955/year |
At ₹2L/month volume, Atom’s ₹2,955 AMC adds +0.12% to your effective rate, almost fully closing the 0.01% headline fee advantage before you’ve even looked at success rates or integration speed.
⭐ Ratings
| Parameter | Rating |
| True Cost (not just MDR) | ⭐⭐⭐ (3/5), Fixed annual charges erode the headline rate benefit |
| SaaS/Subscription Fit | ⭐⭐⭐ (3/5) |
| Ease of Integration | ⭐⭐⭐ (3/5) |
| International Support | ⭐⭐⭐ (3/5) |
| Reliability & Success Rate | ⭐⭐⭐⭐ (4/5) |
| Overall | ⭐ 3.2 / 5 |
Best for: Mid-volume merchants where the per-transaction savings on card rates can offset the fixed charges, typically >₹20L/month GMV.
3. MobiKwik (Zaakpay)
Zero MDR on the first ₹5L GMV, a genuine startup sweetener, with caveats. Zaakpay is MobiKwik’s RBI-licensed Payment Aggregator product with zero setup fee, zero AMC, and 0% MDR on the first ₹5 Lakh of GMV. For a pre-revenue or early-revenue SaaS startup, this is the most cost-effective entry point on a direct fee basis.
Pricing
- 1.85% with Startup plan
- UPI: 1.85% + 0 MDR.
- Cards/Net Banking: 0% to 2.9% depending on method
- Zero setup fee, zero AMC
- Custom/volume-based pricing for high-volume merchants
The honest caveat: the total cost equation includes success rates and ops reliability, not just MDR. Zaakpay’s infrastructure is wallet-ecosystem-first (MobiKwik-centric). Startups relying heavily on HDFC/ICICI credit card authorizations or peak-traffic flash sales may find the success rate gap more expensive than any fee savings.
⭐ Ratings
| Parameter | Rating |
| True Cost (not just MDR) | ⭐⭐⭐⭐ (4/5), Exceptional at low GMV; watch SR at scale |
| SaaS/Subscription Fit | ⭐⭐⭐ (3/5) |
| Ease of Integration | ⭐⭐⭐⭐ (4/5) |
| International Support | ⭐⭐ (2/5) |
| Reliability & Success Rate | ⭐⭐⭐ (3/5) |
| Overall | ⭐ 3.2 / 5 |
⚠️ The ROI trap to watch: If Zaakpay’s success rate underperforms by 8–10% on non-MobiKwik instruments, the revenue lost to failures will dwarf any MDR savings within 2–3 months of operation. Monitor your payment analytics weekly for the first 60 days.
Best for: Pre-launch or early-stage SaaS startups in the ₹0–5L GMV range wanting to minimize upfront payment costs before optimizing for success rate at scale.
4. PayPal India
Best brand trust for international billing, but one of the most expensive for Indian collections. PayPal shut down domestic INR-to-INR payments in April 2021, making it purely an international payment acceptance tool for Indian merchants. The true cost on a USD payment can approach ~9% total once conversion markup and GST are included.
Pricing
| Payment Type | Fee |
| International Goods/Services (receive) | 4.4% + fixed fee by currency |
| Currency Conversion Markup | 2.5%–4% above mid-market rate |
| GST on PayPal’s service fee | 18% on fee |
From a total cost perspective, PayPal is the most expensive payment gateway on this list for per-transaction cost. But the ROI equation is different here: PayPal’s brand recognition in Western markets leads to meaningfully lower payment drop-offs, particularly among US/EU customers who trust PayPal over unfamiliar Indian payment gateways. For Indian SaaS startups with international customers, the higher fee can be offset by improved checkout conversion.
⭐ Ratings
| Parameter | Rating |
| True Cost (not just MDR) | ⭐⭐ (2/5), ~9% all-in cost is high; no domestic billing |
| SaaS/Subscription Fit | ⭐⭐⭐ (3/5) |
| Ease of Integration | ⭐⭐⭐⭐ (4/5) |
| International Support | ⭐⭐⭐⭐⭐ (5/5) |
| Reliability & Support | ⭐⭐⭐⭐ (4/5) |
| Overall | ⭐ 3.6 / 5 |
⚠️ SaaS Warning: PayPal is useless for domestic INR billing. Consider alternatives like Razorpay’s international payments or Stripe for cross-border SaaS billing at better rates.
Best for: Indian SaaS startups with significant international customer bases in the US or Europe where PayPal’s brand trust improves checkout conversion rates.
5. Emerchantpay
A global PSP for SaaS startups going international, custom pricing, strong infrastructure. Emerchantpay is a London-headquartered global Payment Service Provider and acquirer, named “Payment Acquirer of the Year 2025” at the Brit Fintech Awards. It expanded its India presence in 2024. Pricing is custom-quoted, there are no published public rates.
Key Features
- 150+ currencies, 50+ global and local payment methods
- Smart routing and multi-acquirer support
- Apple Pay, Google Pay, SEPA, regional APMs
- PCI-DSS compliant infrastructure; tokenization and 3D Secure built-in
From a total cost standpoint, the absence of published pricing makes pre-engagement cost modeling impossible, you need to request a quote and negotiate. This is a significant friction point for early-stage startups with low GMV who need predictable unit economics before committing.
⭐ Ratings
| Parameter | Rating |
| True Cost (not just MDR) | ⭐⭐⭐ (3/5), Custom pricing; no benchmarks to model TCO upfront |
| SaaS/Subscription Fit | ⭐⭐⭐⭐ (4/5) |
| Ease of Integration | ⭐⭐⭐⭐ (4/5) |
| International Support | ⭐⭐⭐⭐⭐ (5/5) |
| Reliability & Success Rate | ⭐⭐⭐⭐ (4/5) |
| Overall | ⭐ 4.0 / 5 |
6. Unlimit — the cross-border pick for globally-billing SaaS
Unlimit sits in a different lane from the domestic-first gateways above. It’s a global payments infrastructure provider — 15+ years in payments, headquartered in London — offering a single API into 1,000+ local and global payment methods across 150 currencies and 200+ regions. For Indian SaaS founders, the pitch maps almost perfectly onto this article’s true-cost thesis: it doesn’t compete on the lowest headline MDR, it competes on approval rates, accurate settlements and zero fixed fees — exactly the line items where budget gateways quietly leak revenue.
Its India credentials are current and verifiable. Unlimit holds a full Online Payment Aggregator licence from the RBI, and in December 2025 it received the Payment Aggregator – Cross Border (PA-CB) licence — which lets Indian merchants collect from international customers and lets overseas merchants sell into India without setting up a local entity. Domestically it supports UPI, RuPay, net banking, wallets and QR; internationally it connects directly to local rails across LATAM, APAC, Africa, the EU and the UK. One integration therefore covers both your Indian customers today and your global expansion tomorrow.
Pricing
| Item | Detail |
| Pricing model | Custom, quoted per business (volume, risk profile, geography) |
| Setup fee | ₹0 — no setup fees |
| AMC / account maintenance | ₹0 — no maintenance or hidden charges |
| Domestic methods | UPI, RuPay, net banking, wallets, QR |
| International | 1,000+ methods · 150 currencies · major card schemes |
Key Features
- 1,000+ directly integrated payment methods, 150 currencies, 200+ regions — one API
- RBI-authorised (full PA licence + PA-CB cross-border licence); PCI DSS 4.0 certified; data-localisation compliant
- Direct local licences and rails, fewer intermediaries → higher approval rates and 100% accurate settlements
- Payments + payouts + multi-currency in a single layer; subscriptions, instalments and payment links supported
- Fast digital KYC/KYB onboarding with dedicated tech and support managers
⭐ Ratings
| Parameter | Rating |
| True Cost (not just MDR) | ⭐⭐⭐⭐ (4/5) — zero setup/AMC, but custom pricing means no upfront TCO benchmark |
| SaaS / Subscription Fit | ⭐⭐⭐⭐ (4/5) — subscriptions, instalments and payment links native |
| Ease of Integration | ⭐⭐⭐⭐ (4/5) — single API, digital onboarding |
| International Support | ⭐⭐⭐⭐⭐ (5/5) — its core strength; 150 currencies, 1,000+ methods |
| Reliability & Success Rate | ⭐⭐⭐⭐ (4/5) — direct rails, high approvals, accurate settlements |
| Overall | ⭐ 4.2 / 5 |
Best for: Indian SaaS startups selling to international customers — or actively expanding into LATAM, APAC, Africa, the EU or the UK — that want one cross-border partner optimised for approval rates and net revenue rather than the lowest domestic headline rate.
7. BillDesk
India’s lowest card MDR, but a legacy architecture that punishes startups. BillDesk is one of India’s oldest payment processors, deeply embedded with government, telecom, insurance, and financial services. Its card MDRs at 0.85% are among the lowest of any payment gateway, on paper.
Pricing
| Payment Method | Fee |
| UPI – Bank Account | ₹0 MDR, 1-2% Platform Fee |
| RuPay Debit Card | ₹0 MDR, 1-2% Platform Fee |
| Visa/MC Debit (≤₹2,000) | 0.40% |
| Visa/MC Debit (>₹2,000) | 0.85% |
| Credit Cards (Visa/MC/RuPay) | 0.85% |
| Amex / Diners Credit Cards | 0.85% |
| Net Banking (HDFC/SBI) | ₹16 flat |
| Net Banking (ICICI/AXIS) | ₹12 flat |
The total cost trap with BillDesk is the ops and time tax, not the MDR. Modern aggregators let you go live in 2–3 days digitally. BillDesk often requires physical paperwork and manual approval cycles that take 3–4 weeks.
If your startup projects ₹5L/month, a 3-week onboarding delay alone costs you ₹3.75 Lakhs in lost sales opportunity, a hidden “setup fee” that makes BillDesk’s 0.85% rate look very expensive in the first quarter.
Additionally, BillDesk’s checkout flow uses redirect-heavy UX designed for mandated utility payments where users have to pay. For SaaS conversions, redirect-heavy checkouts can lower conversion by 2–3%, far outweighing any MDR savings.
⭐ Ratings
| Parameter | Rating |
| True Cost (not just MDR) | ⭐⭐⭐ (3/5), Lowest MDR, but highest ops/time cost for startups |
| SaaS/Subscription Fit | ⭐⭐ (2/5) |
| Ease of Integration | ⭐⭐ (2/5) |
| International Support | ⭐⭐⭐ (3/5) |
| Reliability & Support | ⭐⭐⭐⭐ (4/5) |
| Overall | ⭐ 2.8 / 5 |
⚠️ The BillDesk paradox for SaaS startups: The payment gateway with the lowest headline MDR on this list ranks last in overall ROI. Saving 1.15% on MDR while losing 3% on checkout conversion is not a win.
Best for: Scale-stage B2B SaaS or government-adjacent platforms processing large volumes (>₹50Cr/month) with institutional clients, not early-stage SaaS startups.
Full Comparison: True Cost, Not Just TDR
| Payment Gateway | Domestic Card MDR | AMC | True Cost Factor | SaaS Fit | Success Rate | Overall Rating |
| Razorpay | 2% | ₹0 | Best ROI after SR & zero AMC | ⭐⭐⭐⭐⭐ | 90%+ (Smart Routing) | 4.8 / 5 |
| Emerchantpay | Custom | Custom | Strong globally; opaque locally | ⭐⭐⭐⭐ | High | 4.0 / 5 |
| PayPal India | N/A (intl only) | ₹0 | ~9% all-in; high brand trust | ⭐⭐⭐ | High (intl) | 3.6 / 5 |
| Atom Paynet | 1.99% + ₹3 | ₹2,955/yr | AMC erodes headline advantage | ⭐⭐⭐ | Moderate | 3.2 / 5 |
| Zaakpay | 0–2.9% | ₹0 | Free at low GMV; SR risk at scale | ⭐⭐⭐ | Moderate | 3.2 / 5 |
| Unlimit | Custom | 0 | Cross-border strength; opaque local pricing | ⭐⭐⭐ ⭐ | High | 4.2 / 5 |
| BillDesk | 0.85% | Custom | Lowest MDR, highest ops friction | ⭐⭐ | Moderate | 2.8 / 5 |
The Verdict: Ranked by True Cost & ROI
The cheapest payment gateway for your SaaS startup is the one that lands the most money in your bank account after all costs, not the one with the lowest number on the pricing page.
- Razorpay: Zero AMC, zero setup fee, 90%+ success rate via Smart Routing, and a native Subscriptions API. The 2% headline rate looks expensive until you run the actual numbers, it consistently delivers the highest net revenue of any payment gateway on this list.
- Emerchantpay: Strong global acquiring across 150+ currencies, smart routing, and multi-acquirer redundancy. Custom pricing keeps it transparent only after a sales conversation, but the infrastructure quality justifies the process.
- PayPal India: High fees (~9% all-in) hurt unit economics, but brand recognition in US/EU markets improves checkout conversion enough to offset the cost for internationally-billing SaaS products.
- Atom Paynet: Competitive 1.99% card MDR, but the ₹2,955 annual software upgrade and ₹1,955 integration fee quietly close the gap with Razorpay’s zero-AMC model faster than most founders expect.
- Zaakpay (MobiKwik): Startup plan with 1.85%. The ROI advantage narrows quickly as success rate limitations on non-MobiKwik instruments start showing up in your payments dashboard.
- Unlimit: Not a domestic MDR play, but the strongest fit on this list for SaaS that already bills internationally. Zero setup/AMC, RBI PA + PA-CB licences, and 1,000+ methods across 150 currencies mean one integration serves Indian customers and global expansion alike — with net economics driven by approval rates and accurate settlements rather than headline rate. Custom pricing is the only real friction for pre-revenue, domestic-only startups.
- BillDesk: The lowest headline MDR on this list at 0.85% on cards, yet ranks last on true ROI. A 3–4 week onboarding delay, redirect-heavy checkout, and opaque custom pricing make it the most expensive payment gateway in practice for any SaaS startup not processing at enterprise scale.
Thanks for this detailed comparison! It’s really helpful to see the true costs laid out like this. As a SaaS startup owner, I appreciate the insights into the different payment gateways. It definitely gives me a clearer idea of which option might be the best fit for my business.
