Payment System Integration: Choose the Proper One for Your Business

It doesn’t matter whether you offer the best paid project management service, food marketplace platform or something else, accepting online payments is a must for almost all online businesses.

7 criteria to select the best online payment system

To get maximum value out of your investment in a payment system, there are some things you need to consider:.

  • Security: One of the key factors and, perhaps, the most important one is to look for a payment solution provider that has top-class security. You will be not only safeguarding the money of customers but also their personal information like credit card numbers, names and more. To make sure you get one, you should look for PCI level 1 compliant payment gateway providers. All online payment providers mentioned in this payment systems review guide are PCI level 1 compliant.

  • Guest checkouts: A survey has shown that over 25% of customers would abandon a cart if they were forced to register an account to complete the checkout. This means you may be losing 25% of your sales if a payment solution uses a third-party shopping cart with built-in enrollment procedure. So always check if the payment gateway provider allows guest checkout.
  • Fees matching your business: If you are choosing a specific payment solution provider it’s clear you’re going to use it not for only a day. Learn about the pricing of online payment providers that is based on things like the type of transactions you will be conducting, e.g. subscription-based or one-time, your sales, transactions frequency, revenue consistency and the market you serve. It helps you analyze if the fees and service agreement require a payment processor to coincide with your business model or not. You don’t want to be paying hefty costs for services you don’t need, or for the ones that lack necessary features.
  • Easy checkout on all devices: It is imperative that you consider online payment providers that allow easy checkout on all devices including mobile phones. Nearly half of e-commerce sales were generated on mobile devices in the past few years, and that number has been only increasing. It’s imperative that the payment solution grants an active checkout experience for your customers making a purchase through both web and mobile devices.
  • Payment methods: If you offer service or product around the globe, you need to ensure that the online payment providers you consider accept payments from most parts of the world. Even the best online payment system providers sometimes don’t provide payment acceptance from some countries. Make sure that there are as many payment options available as possible, like acceptance of several credit and debit cards, mobile payment apps, and support of multiple currencies.
  • Merchant account: A merchant account is used when a customer makes an online payment that is first stored in the merchant account which is different from the actual bank account of the retailer. Once the bank of the customer clears the transaction, the payment is stored in the retailer’s bank account. Though it may seem like an extra step, the payment gateway providers that use it have lower fees than those who don’t, meaning you will save some money on each transaction.
  • Customer support: It is important to note that several payment gateway providers do not provide customer support at all. To avoid hassles and slow support, check if the provider has live technical support, also, see their working hours to get an idea when they’re available.

Now let's proceed to the review of popular global payment systems.
