What is an online payment solution?

An online payment solution is a means by which transactions take place electronically on online platforms like a payment website or e-wallet instead of the credit card terminal. It’s a virtual credit card terminal that allows your customers to pay online. In simple words it is the transaction that takes place between two persons at the two ends of the computer network unlike those taking place via the means of banks or financial institutions. For businesses it is a boon as it makes all financial transactions swift and cashless.


The functions of a Payment solution are twofold:

  • Payment Processor: It works as a medium that processes transactions or give and take of money between businesses. It means if a company ‘X’ wants to make a payment to a vendor ‘Y’ it can do it through a payment solution like Paypal as it will process what is the amount to be given, how it has to be paid and to whom.
  • Payment Gateway: It functions as a gateway through which financial transactions can seamlessly take place. For example if a business is situated at one country and the vendor to whom it is to be paid is situated in another country it serves as the trusted medium to carry out the transactions.
