The choice of payment gateways is one of the most important tasks facing a small business at the beginning of its development. There are many payment providers on the market today. Each of them has a number of features in the field of services offered, specialization, commissions and other parameters. It can be difficult for aspiring entrepreneurs to understand such a variety and choose the best option for their business and everyday tasks. Given the high relevance of this topic, we decided to devote our article to it. We present to your attention the top 5 payment gateways popular among small businesses.

What is Payment Gateways

A payment gateway or processor is a platform for processing payments made by a business and its customers. It is an encrypted software package that processes confidential data (for example, bank card numbers) during transactions. Such services ensure the passage of information about the payment through secure channels from the bank of the buyer of the goods or services to the acquiring bank of the seller. Gateways are responsible for authorizing a transaction on a card or other payment instrument and also protecting money and financial data at all stages of the process.

Processor services include processing payments from bank cards (online or through a terminal), electronic payment systems (PS), and sometimes from other sources (for example, cryptocurrencies). Most modern services of this type are international payment gateways, and therefore they can make payments between banks and PS from almost all countries in the world, with rare exceptions. In addition to processing transactions, they offer a number of additional services. These include enhanced fraud protection measures, reporting tools to track sales dynamics and financial performance, and so on. Merchants can use them to create merchant and dedicated bank accounts to accept debit and credit card payments.

Service Selection Criteria

When choosing a payment gateway, you should pay attention to the following factors:

  • Tariffs and commissions. The cost of services is one of the most important criteria for choosing such a service. It directly depends on how appropriate it will be for small businesses to use it. As a rule, processors charge sellers a fixed monthly fee and a certain percentage of the commission for each transaction. Some platforms do not charge a monthly fee, but compensate for it with a higher percentage of commissions. You should also find out additional nuances: does the service have a free trial period, does it charge a fee for connecting and setting up services, is there an additional charge for chargeback or a refund, how are local and international payments charged, what is the minimum limit on the number of transactions per month, etc.
  • Service type. Today, there are three main types of gateways: redirect (redirect the client to a payment processor like PayPal or Stripe to complete the transaction), hosting (process payments on their own servers, transferring data to banks), and self-hosting (installed on the seller’s servers for local transaction processing).
  • Payment methods. Pay attention to which payment methods are supported by the service you have chosen and under what conditions. For example, which bank PS (Visa, MasterCard, Union Pay, etc.) and other electronic payment instruments (PayPal, Venmo, ACH, eCheck, Bitcoin, etc.) are available to it.
  • Safety. This is another important criterion for choosing a payment gateway. Learn what encryption technologies and other security measures the service uses to protect financial data from theft. In addition, it must comply with the current bank card data security standard (PCI DSS).
  • Integrations and settings. Finally, you should consider the capabilities of the gateway for integration with online stores, CRM, accounting programs and other external systems. The functions of customizing the interface and other elements of the service will be useful (for example, branding the payment web page)
