Payment systems allow customers to make online purchases in the way they are used to. At the same time, merchants have two possibilities: directly connect different PSPs, each time manually setting up the integration, or use payment aggregators. In the latter case, the contract is concluded once, and clients get access to multiple payment systems at once, for example, they can pay from e-wallets, bank cards, or deposit cash through terminals.

How does the payment gateway work?

  1. A customer who has registered in an online store selects the desired product or service from the catalog, which is automatically added to the checkout and forms an order that receives a unique registration ID.
  2. Information about the completed order is transmitted to the payment system, while the site redirects the buyer to the page for choosing a payment type.
  3. The service page displays a list of available options for making a transaction. Having chosen the best option, the client indicates the payment details.
  4. The system verifies the provided data, and, if no obstacles are found, formalizes a secure transaction.
  5. Regardless of the status of the operation, the client is redirected back to the online service page simultaneously with sending data on the results of the request to the server.

How to choose a payment system?

Let’s take a look at some of points every merchant should consider when choosing a payment gateway:

  • Connection conditions. By what methods does the payment gateway integrate with the website? What are the requirements of the payment provider for the website owner? Does the payment provider charge a connection fee? In addition, not all companies work with individuals.
  • What tariffs does the company offer? Some companies have a monthly subscription fee. There may also be additional fees that are not listed on the site, so it is better to clarify this point in advance.
  • Payment methods. An important condition when choosing a payment provider is the availability of a sufficient number of payment methods. A client who does not find a payment option convenient for him can simply leave the site without buying anything. Also, pay attention to how the currency is converted.
