suggestions to offer more products through WHMCS platform.

[Waqas Saeed]

I'm a Domain name and Hosting Reseller; I've integrated the WHMCS that takes order and run module commands on successful transaction; We're happy with the business but it feels now that we should expend the business by offering different services to the vendors, or act as a vendor store;

1) What the modules in the market that offers WHMCS to act as a vendor store? 

To take opportunity of developed modules; What modules are widely used? e.g. if you find good module to offer registration of the events through WHMCS ( Get webinars ID)
