Picked up the category discount, was very simple to install and configure. Works nicely! Will definitely be back for add ons in the future.
We purchased a few addons in the last two years and always very satisfied. And whilr back we had a additional requests for a addon which Softsolid implemented the samr day! I happily recommend them!
I bought several addons from them and they are all very good, I did not encounter any problems.
The support team is excellent.
They answered all my questions in a very short time, I am sure that if there is a problem, they will solve it quickly.
I was fortunate to work with SoftSolid as they suggested many ideas to help us to improve the interaction and onboarding process. Also, I DO really appreciate their fast and "startup"
SoftSolid is doing great forum support as well. When I have encountered an issue they helped me to fix it personally with free of cost although I am not their customer. Now, am planning to buy some addons from them if any of them meet my business needs.

Great Softsolid!!
Great add-ons came from great company with great developers.

Good service
Excellent support, friendly, approachable and I would certainly not hesitate to reach out to them again!
We've bought and used add-ons that extend the promotions functionality of Cs-cart. All of them have fulfilled our expectations. They are easy to install, set up and get them running in a few clicks. The performance is perfect and without issues.
Clapping my hands. They are listening their customers and they hear their needs. Keep it good work and build trust.
