Best Payment Gateway 2026

Frequently Asked Questions

What is the best payment gateway for a startup?▾

Stripe is the default for most SaaS and online businesses - best-in-class developer experience, broad country support, and a deep feature set. Paddle and Lemon Squeezy act as merchant of record and handle global sales tax for you, which is a very large practical advantage for small teams selling internationally. Razorpay leads in India, and Adyen serves large enterprises with complex needs.

What is a merchant of record, and why does it matter?▾

A merchant of record is the legal seller. With Stripe, you are the seller, so you are responsible for registering and remitting VAT, GST, and sales tax in every jurisdiction where you have customers - which becomes a real burden fast. With Paddle or Lemon Squeezy, they are the seller of record and handle that entirely, in exchange for a higher fee. For small teams selling globally, that fee is usually worth it.

How much do payment gateways cost?▾

Roughly 2.9 percent plus 30 cents per transaction is the standard baseline for card payments in the US, with higher rates for international cards and currency conversion. Merchant-of-record providers charge more (around 5 percent) because they absorb tax compliance and chargeback handling. At high volume, interchange-plus pricing negotiated directly is meaningfully cheaper than flat-rate.

What is the difference between a payment gateway and a payment processor?▾

A payment gateway is the technology that securely captures and transmits payment information from the customer to be authorized, essentially the front door of the transaction, handling encryption and communication. A payment processor is the service that actually moves the money, communicating between the customer's bank and the merchant's bank to complete the transfer. The gateway passes the details; the processor settles the funds. In practice many modern providers bundle both into a single service, so merchants deal with one company, but technically they are distinct roles in the flow of an online payment. Understanding the distinction helps when comparing providers who separate or combine them.

How do payment gateway fees work?▾

Gateways typically charge per transaction, commonly a percentage of the amount plus a small fixed fee, and some add monthly fees, setup costs, or charges for features like refunds, chargebacks, or international cards. Pricing models vary: some use flat-rate pricing that is simple but not always cheapest, while others use interchange-plus pricing that can be lower for higher volumes but is more complex. Cross-border and currency-conversion transactions usually cost more. When comparing providers, look at the total cost for your typical transaction size and volume, not just the headline rate, and factor in any monthly or hidden fees that affect the real cost.

What is PCI compliance and why does it matter?▾

PCI DSS (Payment Card Industry Data Security Standard) is a set of security requirements for any business that handles card payments, designed to protect cardholder data from theft. It matters because handling card details carries serious security and legal responsibility, and non-compliance can lead to fines, higher fees, and liability if data is breached. Using a reputable payment gateway greatly reduces your compliance burden, because the gateway handles the sensitive card data on its secure systems, so the details never touch your own servers. This is a major reason merchants use gateways rather than processing cards themselves: it offloads much of the security and compliance responsibility.
