  13. Other Payment Providers on OMR Reviews

Nowadays, anyone who still has to give their bank details and card numbers when shopping online will probably wonder and cancel the purchase as quickly as possible. After all, we are becoming more and more sensitive when it comes to dealing with personal data and are very reluctant to give them out just like that. So that as a dealer*in and online shop operator*in you do not lose your customers and cause fewer shopping cart abandonments, you should definitely offer your customers alternative payment options! We show you the best payment service providers and how you can create an easy and convenient shopping experience for your customers.

What is a payment provider?

Payment providers, payment service providers or Payment-Service-Provider allow you to connect online payment methods in online stores. They offer you as an operator*in and dealer*in the possibility to authorize payments and pass on transaction information to banks. The idea is to process a secure payment process for both sides and to give customers the flexibility to choose their preferred payment method themselves.

Why is a payment provider important for online retailers*in?

By integrating payment providers into your online store, you have the opportunity to offer your buyers*in addition to credit card payments or purchase on account further payment options. So your clientele is not limited to a certain method, but can freely choose which one they like best at this moment. This flexibility can therefore also lead to higher sales, as there are fewer purchase cancellations from people who do not want to give all their bank details at once, but prefer to process payment through a trusted payment service provider. Moreover, you can offer your customers the possibility of installment payments and still receive the full amount at the time of purchase.

Many shop systems and webshop tools already have interfaces to payment providers. Thus, the integration into your online shop is child's play and you can offer your customers the perfect service!

What are the benefits of payment providers?

The integration of payment providers into your shops brings the following advantages:

  • Customers can have payments processed safely with a method of their choice.
  • The offering of reputable and well-known payment providers strengthens the branding and reputation of your own shop
  • Lesser workload due to automated processes
  • Payment service providers take on the risk of payment defaults, as they stand in front of the customer*in as a direct contractual partner
  • Goods can be shipped faster, as the payment security is guaranteed
  • Many shop systems already offer integrated interfaces to payment service providers

What should you look for when choosing a payment provider?

If you decide for one or more payment providers in your online shop, you should pay attention to a few things and take them into account when making your selection. The most important criterion is security. This primarily includes sufficient encryption, so that sensitive data does not fall into the wrong hands. Many payment providers are already legally obliged to comply with certain guidelines. Therefore, you don't need to worry about the big providers.

In addition, you should deal with the questions of how high the fees for you are and how quickly you ultimately get your money. Possibly you also want to offer the possibility of recurring payments, so-called recurring payments. This can make sense, especially for subscription-based products or services, and should therefore be checked beforehand.
