Any business that wants to sell its products and services on the Internet needs a payment gateway. This is a software solution that, in semi-automatic mode, removes funds from the buyer's account and transfers them to the seller’s account. The availability, speed, security, convenience and price of remittances depend on who provides such a service. This means that every online retailer seeking to increase sales should carefully consider which payment gateway to choose and how to integrate the option they like into their website.

From our article you will learn:

  1. How to choose the payment gateway integration method.
  2. How to choose a specific payment service provider company.
  3. How to integrate a payment gateway into your website.

Choose the integration method

Hosting Payment Gateway

Redirects customers from the checkout page on your site to the web-based payment processor platform. Simple and convenient, but it requires additional actions from customers, which worsens the user experience. PayPal is a prime example of such a solution. If you plan to use hosting payment gateways, first find out what services your potential customers are familiar with, for example, using a social media survey.

Payment Gateway on the Site scheme

Advantages. Hosting gateway integration requires significantly less time and resources - 1-3 days. In addition, when using an external payment gateway, payment processing and storage of business data of users are performed by the service provider, therefore, the seller does not have to follow the PCI DSS security rules, which greatly simplifies the life of the online business.

Disadvantages. Redirecting buyers to third-party resources reduces conversion, especially if on the external page they need to trust an unfamiliar service. If you connect to a well-known payment service provider, when changing partners, there may be problems with maintaining the customer base. So, PayPal, when the relationship is broken, keeps the data of users through their services.

Integration. Typically, integration guidelines can be found on vendor sites. As an example, you can read the PayPal Express Connection Guide. In short, it says that you need to take a piece of JavaScript code and integrate it into the site code. In this way, you place a button that activates PayPal's REST API and payment stream to process the transaction.

Suitable for a small local online business, which is more convenient to use external payment services. It is easier and cheaper.

Integrated Payment Gateway

Unlike hosted payment gateways, where shoppers leave the checkout page, integrated solutions connect to your site via the payment gateway API. By choosing this option, you will be responsible for the payment process and compliance with various security requirements. You will also need to open a trading account, since it will be the payments from debit and credit cards of buyers to it.

Advantages. The store retains full control over transactions and customer data. This allows you to create your own customer base, which will always be with you. In addition, integrated solutions provide an opportunity to customize payment processes willingly and adapt them to the needs of a particular business, site and target audience.

Disadvantages. To use an integrated gateway, your site must be compliant with the PCI DSS security rules, since all customers' credit card information will be stored on your servers. In addition, usually with this approach, all the costs of maintaining the infrastructure of the payment system and the associated costs are falling on your shoulders.

Integration. The payment gateway is connected to the site via an API, therefore, you will need a development team - own or outsourced. Most providers of non-hosting payment gateways have well-described integration guides, API links, or partner development portals.

Suitable for medium and large companies that rely on improved user experience and the development of their own brand.

Choosing a supplier company

# 1. Modern or classic

Payment Gateway on the Site Types
Types of payment gateways
The main difference between modern and classical payment gateways is the presence of a trading account with the latter. Trading account is a commercial bank account with two encumbrances:
  • firstly, the seller cannot directly manage the funds in the account;
  • secondly, payments received on such an account are deposited and temporarily withheld while the bank processes them, which takes several days. After that, the money goes to the usual commercial account of the seller.
 

The classic payment gateway is suitable for medium and large enterprises working with a large number of daily online transactions, as they can work directly with banks, which reduces transaction fees.

However, this approach is quite burdensome at first: you need to submit an application, pay for and set up a dedicated trading account, and also need technical knowledge to integrate the account through the API. Examples of classic gateways are Authorize.Net, 2Checkout and WorldPay.

Modern payment gateways, such as PayPal and Stripe, combined the trading account and gateway into a single service, so it is easier to open and configure them. All you need is a valid bank account for accepting payments. But the transaction commissions for these gateways are higher. This approach is usually used by small companies that want to save on start.

# 2. Gateway security

When choosing a payment service provider, pay attention to the following points:
  1. SSL encryption and digital signature. Protection against hackers.
  2. PCI DSS. Personal data protection and anti-fraud.
  3. Check CVV2. To complete a transaction, the cardholder must provide a credit card number and a three-digit security code printed on the back of the card.
  4. Dynamic IP addresses. Denies access to the service if the request did not come from your IP address. New IP addresses are connected via additional verification methods: SMS, call to phone, confirmation by email, etc.

# 3. Encryption Standards

The payment solution provider handles the confidential payment information of your customers, and if there is even a small breach of confidentiality, it may badly affect the reputation of your company. Therefore, check how vendors encrypt this data. For example, the payment gateway EBizCharge tones the data and completely removes the card data. Other companies use seamless integration with other platforms, which significantly reduces the likelihood of human error and provides greater visibility of reports.

# 4. Available payment methods

According to WorldPay's global payments report for 2018, about 24% of people were forced to abandon purchases (goods put in the shopping cart) due to the fact that among the payment methods there was no option they needed. The same report says that more and more people prefer to use not the usual credit cards, but payment methods such as Google Wallet, Google Wallet or Visa Checkout. Therefore, when choosing a trading gateway, check which payment methods your customers prefer to use and look for suppliers that cover these requests.

Another important aspect is multicurrency support. This is important for companies that conduct international activities and want their customers to pay in the currency convenient for them. Usually payment gateway providers provide such a service for a fee: a fixed monthly fee or additional fees for trans-currency transactions.

# 5. Legal compatibility

Depending on your jurisdiction and web platform code, many payment gateways may not be available. For example, due to the fact that the payment service has no right to work in your country due to the absence of a corresponding license or sanctions. In addition, many payment services prefer not to work with a business that is associated with gambling, erotica and porn, narcotic substances and the arms trade.

# 6. Transaction processing speed

If you want to improve your user experience and execute transactions as quickly as possible, you will need a processor capable of processing payments within seconds, rather than several days. Here is a list of the fastest processors according to Spreedly data for the last three months (March-May 2019):

# 7. Reporting features

Depending on your business, you may need a payment solution with the ability to create detailed reports. For example, to study all operations for a certain period of the entire business or individual product (department). Or to learn statistics on chargebacks or commission costs. Gateways offer different formats and types of reporting, and to make the right choice, this issue needs to be studied in advance.

# 8. Fraud Detection

Even when choosing a payment gateway, you must make sure that it has security features designed to protect against fraud and counteract such. The minimum program - the presence of PCI DSS. This is a standard of information security, which is mandatory for all organizations working with credit cards. The standard was introduced in 2004 and has several gradations - from the simplest "1.0" to the most advanced to date "3.2.1".

In cases where counteraction to fraud is of paramount importance to you, you should pay attention to suppliers such as CyberSource, who specialize in such moments. Here are examples of the detection tools they use:

  1. Address Verification Service (AVS) verification.
  2. Tracking the number of authentication attempts.
  3. Use of biometric data.
  4. Verify shipping address.
  5. ID verification.
  6. Identity check.
  7. Geolocation.

# 9. User experience

Payment gateways should be convenient for customers and your staff. And this concerns not only the design and usability of the interface, but also such things as support service, text and video instructions, the availability of a convenient feedback form and the like. In addition, it is also important that the payment function works normally on mobile platforms.

# 10. Costs and fees

It is very important that when choosing a financial partner you correctly calculate all the expenses that will be required to integrate the payment service and pay for its services. Usually, suppliers charge several fees at once.

Here are some of them:

  1. Account Registration / Connection Fee.
  2. Set up of the payment gateway.
  3. Processing normal and currency transactions.
  4. Fee for connecting a special payment method.
  5. Refund fee.
  6. Monthly fee.
Payment services decide how to monetize their services. For example, Stripe has no connection fees or monthly fees. The company charges 2.9% of the amount of each transaction + $ 0.30. This means that if you bought a product for $ 100, you will end up with:

96.80 dollars = 100 - (100 × 2.9%) - 0.30

You can find tariff plans for Authorize.net, PayPal, 2Checkout, Stripe, BrainTree, Forte, Worldpay, BrainTree, Payflow Pro and Payments Pro via these links. There you will also find answers to frequently asked questions about additional fees. But always keep in mind that you may have missed some information or did not have time to add it to the site, therefore it is better to contact the gateway of interest and communicate directly with its representatives.
