Payment gateways are the first step in the online payment process, and they have been crucial in helping e-commerce companies and online payment providers more easily accept online transactions. 

The best payment gateways serve as the online version of a payment terminal and front-end processor for online and mobile sellers. They often sell bundled services that include payment acceptance, data reporting, and fraud management.

Insider Intelligence expects that as global retail e-commerce volume continues to rise, revenue the companies processing these payments can collect as fees will increase from $82 billion in 2018 to $138 billion in 2024.

Furthermore, payment companies, merchant acounts, and consumers are all shifting to digital, which is giving gateways more influence. In the US, e-commerce sales totaled $146.2 billion in Q2 2019, making e-commerce nearly 11% of retail overall.

Given this, it’s understandable that more gateways will want to get a piece of the pie. But as more companies pour into this space, it will create difficult decisions for merchants. Which payments gateway provider should you use? What are the inherent advantages and disadvantages of each?

Below, we’ve compiled a list of the industry’s leading payment companies to help you decide. Keep in mind that no one company or gateway has an overwhelming share of the market, and competition among these companies remains strong.

Worldpay

UK-based Worldpay is one of the longest-tenured online payment platforms. The company provides several payment services for both online and in-store channels, and in 2018 was deemed the No. 1 acquirer by purchase transactions in the US. In 2018 Worldpay was acquired by US rival Vantiv, and the combined entity was later purchased by US financial services company FIS in 2019. 

Ingenico

Ingenico is a legacy payments processor that initially stood out as a top provider by handling in-store card payments – and thus is popular among companies where in-store payments is a top priority. Today, the company offers payment solutions across in-store, online, and mobile channels. 

Amazon Payments

Amazon’s proprietary credit card payment processor supports payments on its parent’s website, which gives it instantaneous access to high payment volume. Furthermore, it has expanded by offering its platform to other merchant sites – an attractive proposition for third-party merchants. One disadvantage, though, is that the gateway helps Amazon strengthen its brand, which many e-commerce merchants must compete against.
