Reviews about our company

Another project with Robert - integration with the First Data payment system / Payeeze - https://marketplace.cs-cart.com/add-ons/integrations/integration-with-payeezy.html

SoftSolid directly cooperated in this integration with Peyeezy, relieving us of the interchanging technical correspondence.

Integration started at the expected time, all errors found and corrected before implementing the solution. SoftSolid works flexibly, is orientated to the customer's needs. Introduced most of the suggested changes without lengthening the lead time.

As a new start-up, we've had to purchase quite a few add-ons for our multi-vendor marketplace and have also come across some pretty poor customer service along the way, so it was really refreshing to find such a responsive company with excellent customer service. I will most certainly be purchasing our future add-ons from you guys. Thank you so much!

The company is very serious and pays attention to its customers, I couldn't put 10 stars only 5.

I definitely recommend apps and customizations.

very professional and reliable partners. Working with them is a pleasure. We've already installed a few of their add-ons, and it's certainly not over!

We have been cooperating with Soft Solid for several years. It is a reliable and honest company that knows the CS-Cart software perfectly. We used their standard add-ons as well as they created individual solutions for us. They can do a lot for a reasonable amount of money. Their addons and solutions are not the cheapest, but it simply work. We recommend Soft Solid.

SoftSolid has always provided exceptional customer service.

We use a handful of their add-ons and in the rare case where we need support, they are always very fast to respond and come up with a suitable solution in no time.

SoftSolid is a very reliable and solid company. I requested them to develop a custom add-on for me, which will work only for Polish territory. It was delivered on time, and basically ready to be implemented in my production store, with only a few cosmetic changes left. The communication was fluent and overall there were no problems during development process. I fully recommend cooperating with this company.
