Understanding the Core Costs: TDR, Setup Fees, and Annual Maintenance

For any Indian business moving online, understanding the payment gateway integration cost in India is a critical first step. This cost isn't a single number but a combination of several key charges, the most significant of which is the Transaction Discount Rate (TDR). TDR is a percentage fee charged by the gateway on every single transaction you process. For instance, a TDR of 2% on a ₹1,000 sale means the gateway keeps ₹20. In 2026, typical TDRs in India are highly dependent on the payment mode:

• Credit & Debit Cards: Typically range from 1.8% to 2.5% for domestic cards.
• Net Banking: A similar range, often around 2%.
• UPI: Currently close to 0% for most transactions, a major advantage for businesses. However, this is subject to regulatory changes.
• Digital Wallets: Can vary from 1.5% to 2.5%, depending on the wallet provider.

Next are Setup Fees. In the past, this was a significant upfront cost. However, the competitive landscape in 2026 means most major players like Razorpay and PayU have completely waived setup fees for their standard plans to attract SMEs. You might only encounter these for highly customized enterprise-level solutions. Similarly, Annual Maintenance Charges (AMC), a yearly fee for using the gateway's services, have also become rare for standard plans. While this is great news for businesses, it's crucial to read the terms and conditions carefully, as some gateways might re-introduce these fees or bundle them into premium packages with value-added services.

Beyond the Obvious: Uncovering the Hidden Costs of Payment Gateway Integration

Focusing solely on TDR and setup fees provides a dangerously incomplete picture of the total cost. Several "hidden" costs can significantly impact your bottom line if not anticipated. The most common is the chargeback fee. When a customer disputes a transaction, and you lose the dispute, you not only refund the transaction amount but are also hit with a penalty fee from the gateway, which can be anywhere from ₹500 to ₹750 per incident, plus GST. Another major hidden expense is the integration and development cost. Unless you're using a simple plug-and-play solution for a platform like Shopify, you'll need developer hours to integrate the gateway's API into your website or app. This can range from a few hours to weeks of work, representing a substantial upfront investment.

A payment gateway's true cost is not its advertised rate, but the sum of its transaction fees, development effort, chargeback penalties, and the operational overhead of managing it.

Other costs to watch for include fees for international currency conversion (forex markups can be 2-3% above the TDR), fees for batch settlements, and the non-negotiable 18% GST applied to all fees. Forgetting to account for GST on your TDR and other charges can lead to a nasty surprise when balancing your books. A seemingly small 2% TDR is actually 2.36% when GST is included.

2026 Cost Comparison: Razorpay vs. PayU vs. Stripe for Indian SMEs

Choosing a gateway is a strategic decision. For Indian SMEs, the choice often comes down to three giants: Razorpay, PayU, and Stripe. While their core offerings are similar, their pricing structures and strengths cater to different business priorities. Here’s a comparative look at their standard plans for 2026:
