Top 4 Online Payment Systems for Ecommerce in 2021 | Pros & Cons (2024)

If you read this article, you are probably looking for a reliable, safe, easy online payment solution with the lowest fees for your business. Unfortunately, the choice can get complicated. Intricate pricing systems, nuances of setup, and features are overwhelming.

In this guide, we are going to compare the top payment systems on the market: PayPal and Stripe, to their specialized counterparts Amazon Pay and Shopify Pay. The pros & cons with a detailed comparison table will help you choose what’s best for your eCommerce business.

But first, let’s understand the mechanism behind online payments and why you need a payment system anyway.

How online payment systems work

Knowing how the money travels from customers to you and back is helpful to understand where the fees come from.

Let’s imagine the simplest scenario: a one-time payment in the US. There will be four major players:

• Merchant – it’s you, the business;
• Cardholder – that’s your client;
• Issuing bank – the bank that issued your client’ credit card;
• Acquirer, or a merchant bank – the bank that will accept and deposit the payment on your behalf. Usually, they process the payment (route it through a card network to the issuing bank). Sometimes, they partner with third-party processors.

To receive the payment, you will need to set up the work with each of them. First of all, you’ll need an account at your merchant bank and to establish a relationship with a payment processor (if they are separate entities).

That’s when payment aggregators or payment facilitators (PayFacs)like PayPal or Stripe come into the game. (They are often called payment gateways, too). That’s a piece of software that links your website to the processing network.

Using a PayFac, you won’t need a merchant account, because you will be using theirs alongside all other people. The technology behind it is such that the information about millions of users and transactions is bundled to make it indistinguishable – and, therefore, secure.

Businesses use gateways because they simplify the process a lot. Apart from providing ready-made checkout forms, they take the responsibility of storing and protecting all the fragile credit card data (it never touches your website). In other words, they take care of (almost) all PCI Compliance, and that’s a lot of bureaucracy if you had to deal with it yourself.

Of course, if you become a highly successful business, you will probably need your own merchant account and the responsibility will be all yours. But that’s another story.

So, who gathers fees in the process?

• Issuing bank takes an Interchange Fee, usually a fixed price + a percentage of each transaction;
• Credit cards can also charge an Assessment (or Scheme) Fee;
• Merchant banks, payment processors, and gateways gather a Markup Fee, calculated in a similar manner.

If your product’s price was $100, the total fee (Network Costs) would usually be about $2-3, depending on the partners you choose.

Now, let’s dive into the detailed comparison of payment gateways to pick the best solution for your type of business.

What to consider before choosing a payment system:

• All the types of their transaction fees
• Geography (whether your business is international)
• What you want your payment to look like (card or non-card, point of sale payments, etc.)
• Additional services (extended fraud prevention, payment plans for expensive purchases)
• Resources (whether you want to allocate time, money, and a team of professionals to make a tailored solution).
