Hi everyone! Not sure about your experience with WHMCS Smarters but ours was really great. They have very good products ( the one page order form is stellar ) and more than this they accepted to do some extra work for us to modify the order page as we wanted. The price is AWESOME! Just try to talk with a dev company to see how much they will ask you for this kind of project.

Our poject was done in a few weeks because we had some custom things that we modified and it took some time for dev but in the end everything was as expected. I really recommend these guys. I want to give a BIG THANKS to Harmandeep - he was the PRO dev that was able to help us with most of our issues.

Hi Mahmudul,

Did you buy this module and used it ever?

Also, I have many clients using this solution happily.

About Price: As I mentioned in the description, first we have to design a mockup according to the website then we integrate it according to main website design. it's not a pre-built solution.

No one can judge the module without using it
