Multi-store website

One of the key requirements of the client, and a significant challenge for the NopCommerce engineers was of a multi-store website. To implement this:

  • A merchant signup module was created which called a web service which dynamically hosted a store in the IIS server
  • Made an entry into the DNS server for the new sub-domain
  • Dynamically created a database for each store hosted
  • Configured the website
Admin site

The admin site was developed in ASP.NET MVC 2 for management of stores and merchants. This involved:

  • functionality for activation/deactivation of stores
  • Creating hosting plans where back-office personnel can select/deselect features for the merchant
  • Manual Invoice creation for merchant according to the features and hosting plan he has opted for
  • PCI compliance by encryption of credit card number and CVV2

The following features were integrated in nopCommerce store:

  • Integration of Fedex , UPS , USPS shipping web services and printing of the labels
  • Integration of TSYS (Vital) and Elavon payment gateways using a third part component Software - E-Payment Integrator
Store Termination Windows Service -

A windows service which runs every night and cleans up the target store hosted in IIS and detaches the database.

Billing Service

The billing service runs every night and performs:

  • Automated invoice creation for the merchants depending upon his/her plans and features selected
  • Payment processing using TSYS Payment gateway and Authorize.net and email notifications for payment processing results
CC_Turnkey web service

This web service takes credit card information and payment gateway ID as input,  and processes the payment using these gateways – Elavon, Payflow Pro, First Data , Innovative, LinkPoint, EWay, Vital and Website Payments Pro (Paypal Pro)

Email Drip Campaign Windows Service

This was a new feature added in the NopCommerce shopping carts that:

  • Takes the user input date and email address as a reminder for a particular product. A user is able to set up to five reminders.
  • The Windows service runs every night, and connects to the each of the store databases dynamically and retrieves all reminders due in 5 days and 7 days. It then generates a reminder email along with the top 4 products in the category for which the customer had set the reminder for.

Multi-store websites

The multi-store websites allowed merchants to set up multiple eCommerce store-fronts by just signing up, choosing a plan and setting up their own stores.
