Factors to consider while selecting a payment gateway for your business

Your decision making of choosing the best payment gateway for your business will be highly dependent on the fact that if you sell online only as a direct to consumer brand or you sell both online and offline.

Although your use cases may vary, we feel that the below factors cannot be ignored.


For obvious reasons, price has to be one of the top factors to consider while selecting a payment gateway.

Pay special attention to fraudulent transactions and chargeback fees.

Most providers do not make it clear about their pricing on chargebacks. If your return to origin (RTO) is significantly higher, then you may end up paying a lot more in transaction fees to the payment gateway.

For example, if your average order value is $100 and your volume is about 2000 orders per month with a 60% RTO. This means 1200 orders are returned back to you. On an average, a payment gateway charges 2.5% + 30 cents per transaction. This comes to $5600 as payment gateway charges. With chargebacks of 2.5% per transaction, you'll end up paying an additional $3000.

Secure online payment processing

3D Secure 2.0 is a protocol introduced and implemented by payment processors. It's sole purpose is to authenticate card holders in a card not present or CNP transactions. Authenticating credit cards and various payment options involve understanding transaction context, customer history and other factors. These help in mitigating risks associated with online payments.

A payment gateway is a PCI Service Provider Level 1 if it implements the above and additional security mechanisms to be on top of latest security threats and vulnerabilities associated with online payments. Most providers usually list down the security protocols and risk management features implemented by them.

Double check if there are no additional charges for processing payments from a gateway which is PCI Service Provider Level 1.

Compatibility with your current tools.

Payment gateways like Stripe, Paypal have plug and use components for major ecommerce platforms and support integrations with external tools like Zapier, Typeform, custom payment pages and with marketing email tools like Mailchimp, Activecampaign, etc.

Selecting a provider which will do most of the heavy lifting for you is recommended rather than having a steep learning curve or building custom components.

High conversions

Alternative payment services providers like BNPL give an advantage of improving conversion rates significantly.

Although it might seem to select the BNPL option as a no-brainer, keep an eye on chargebacks and default payments. Since most of the shoppers pay only a quarter of product value at checkout, it will improve conversions but the BNPL industry is also facing the issue of high order returns and refunds.

With each transaction and its return, you may end up paying a lot in transaction fees to BNPL providers.
