As purchases in online stores become more relevant in the consumer’s daily life, having the ability to accept a wide variety of payment methods becomes increasingly important in an online store. Therefore, choosing your payment gateway well not only saves you headaches, but can also make the difference between a completed sale and an abandoned cart.

What is a payment gateway?

It is the bridge that guarantees the secure transfer from a bank account or cards to the e-commerce account. It must be efficient and, above all, have a promise of data confidentiality, so that it keeps the information of the consumer and the business safe.

Factors to consider when choosing a good payment gateway

Choosing a single tool that is so important for an online store becomes even more complex with all the options that exist in the market. Some points that you should keep in mind when choosing are:

Variety in payment methods

The goal is to offer the greatest possible flexibility in terms of payment types, even in some e-commerce platforms, it is also important to accept cash deposits in stores, which allow users who do not have a bank account to make their purchase online. The more options you accept, the easier it will be for the final buyer.

Transaction fees

The commission of the payment gateways is a key factor in its choice, especially so as not to affect the profit margin of your business. If you sell products with a low profit margin, the ideal is to opt for a gateway with low commissions so as not to eat into the profits. On the other hand, if you sell higher value products, you can afford to pay a slightly higher commission, as long as the gateway offers you extra advantages such as greater security, a top user experience or brand recognition that generates trust.

Security and integration

Your payment gateway must integrate seamlessly with your e-commerce platform, shopping cart, and any other tools you use in your online store. That integration has to be fluid and without friction. On the other hand, this process is expected to be secure and protect the financial data of the buyer. Some payment gateways even have integrated fraud detection tools for added security.

Promotions and brand recognition

There are payment gateways that are much more recognized by users than others, and having at least one of these in your online store always adds points because it gives the customer confidence. Another advantage of the most positioned payment gateways is that they are constantly making promotions to which they can invite you to participate. In some cases, they even assume the cost of the discount themselves, which is a great point because it does not affect your pricing strategy or your margins.
