Parameters to choose an international payment gateway

As a freelancer, you might be interested in a cost-effective service. It would be best to focus on the following essential parameters when choosing an international payment gateway.

  1. Ease of integration: As a freelancer, you will be doing integration for yourself or your clients. You may not have an army of developers to back you up. The payment gateway provider should give good SDKs and a simple API.
  2. Service charges: When you operate on a shoestring budget, it is essential to save every penny. When it comes to payment processing, even a 1% difference will make a significant change.
  3. Payment options: For your online business to have a better conversion, your checkout process should have lesser friction. One key aspect is providing the maximum possible payment methods and coverage of more card providers.
  4. Reputation: Your customers will speculate before sending their hard-earned money. They want a dependable channel, security, and trustworthiness. Your payment gateway provider's positive or negative reputation gets transferred to you. So choose an international payment gateway provider with a good reputation.
  5. Settlement period: Once you get the money, the international payment gateway provider will take time to make it available to withdraw to your bank. Certain providers will have a minimum amount and a stipulated hold period. Ensure that it is a smaller duration.


Choosing an international payment gateway is a complicated process. It is not something that you can change quite often. Once selected, it will persist with you for a more extended period. It is the most critical part of your online business. Per my assessment, I have presented you with the top ten international payment gateway. Though I have given it as a ranked list, you can choose one among them without any fear. Sometimes a combination of the two may also be needed depending on your business and customers. Think of the five parameters I have listed and validate them against your preferences, then choose the payment gateway.

Best wishes!
