Solid indeed. Always very quick help and all the addons seem to work perfectly as described.
Works very well, bought and recieved addon same day, I like the flexibility that you can change the sort order of many different things
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
Robert from SoftSolid did exceptions work finding a bug in my website that was caused by 3rd party add-on. He always answers quickly and his answers are professional. Can be recommended as a knowledgeable and trustworthy CS-Cart partner.
For several years, the cooperation with Soft-Solid has been successful. We are glad that the response time to reported problems is getting faster. They act prudently and reliably, always finding a solution to the problem. We recommend!
I have been in contact with SoftSolid for over 2 years now. This is not only a team of devoted people with passion, but also team of super experts who can solve and custom build any addon that is needed. I highly recommend Soft Solid and their addons. 5 stars!
Bought an addon from SoftSolid. It didn't work directly after installing because we were using a specific PHP version. We have sent a mail to the developer, and received a quick respons. They have checked and fixed it with the PHP version we provided very quickly.

We will certainly buy addons from Softsolid again in the future.
Finally something what works. I purchased the "Exchange Rate Update" addon. No need to contact developer, it just worked as promised. Thanks.
We purchased "Sales in measures of fractional" add-on. Great team. They helped us to make additional changes in the add-on according to our needs.
Fast communication and always ready to help.
We cooperated with "SolidSoft" on the implementation of a new form of delivery - "Paczkomaty". Our store has a lot of custom changes. Often standard add-ons do not work properly after installation. They require adaptation to our system. Everything went quickly, smoothly and without much hassle.
