Suggest client panel for SEO services.

Hi guys.
I am selling seo services from my website and need good admin area/panel for orders management.
I found this one : http://www.blackhatworld.com/seo/sell-more-services-client-panel-for-your-agency.650949/
but would like something more.
Any help ?

i think that service is very good except the price, other option you can check in the marketplace and see what service they use on their sales thread.

I think that panel you mentionned can offer what you need

You're just looking for a CRM and billing system? You've a thousands of opensource for that, if all you want is to manage business abstracting the SEO services itself from that platform (which i believe you're) i can recommend you a few i'm running with costumers.
It's also easier to adapt existing SEO services you may already be using like seopanel.in if aren't using a closed service.

This is a good one. Start with it.
