Processing payment in an online store. Part I

Olga Karpman — March 23, 2007

Most online merchants like to offer their customers a number of payment options to choose from. The most common and preferable by both customers and merchants is payment thru Internet. Merchants choose it as an alternative to cash payments, checks and money orders, though these forms of payment are still offered in online stores. Payment thru Internet is performed via a payment gateway – an e-commerce service that provides quick and secure transfer of funds between a buyer and a seller bank accounts. Such names as Authorize.Net, 2checkout, LinkPoint, CHASE Paymentech, and many more are examples of major and reliable payment gateways. Though there are certain differences in their services, all payment gateways allow debit and credit card processing similar to the mechanism depicted on the picture below:

 Debit and credit card online processing

To accept credit card payment in online store, a merchant is required to have a merchant account and be registered with some payment gateway (choose payment gateways according to your liking; one of the major differences between payment gateway companies is pricing - sign-up price and comission that they charge per transaction).

Setting up payment thru a payment gateway in Shop-Script based online store is a straight forward process and does not require any knowledge of HTML or programming skills. Shop-Script supports payment processing thru many payment gateways.
All Shop-Script payment modules are designed according to payment gateway integration specifications (each payment gateway company provide its own integration workflow). Many modules are certified by payment gateway companies, e.g. Authorize.Net, PayPal, 2checkout, CHASE Paymentech, and others.

Each payment module can be installed and configured from your store backend (listed on the Modules -> Payment Modules page). A module can be easily installed and added to the list of available payments. A store administrator only needs to enter payment gateway account details in module settings (e.g. login and password), so that payment gateway can authorize payments made by customer to merchant’s account.

Once a module is installed in the store, it needs to be tied to a payment type, which is done in a store’s backend area on Configuration -> Payment page. A payment type will be offered to a customer when placing an order and information on the associated payment gateway. Beside an associated module, an administrator needs to indicate shipping options, which will be offered to a customer with the payment type. Tax calculation option is enabled by default. A store administrator can turn it off if needed. There are also text fields, where payment type description and notification message can be typed in. The picture below shows three payment types setup in the store, their associated modules, available shipping choices, tax calculation option and other settings:

Part 2 of this post will appear in the blog early next week and will cover how payment options are presented to store customers in frontend.
