Why upgrade CS-Cart


Slow website

Latest CS-Cart and Multi-Vendor versions use latest PHP and utilize the technologies to assure fast load speed on any device.

not friendly

Poor mobile front

Upgrading to a new version gives you a fully responsive web design. It also enables the integrity with the newest mobile-first themes.


Lack of functionality

Upgrading adds fixes and features to your web store which were not included previously. Plus, you’ll be able to use the add-ons that do not support early versions.


Expensive service

Old version of CS-Cart and Multi-Vendor need more time and effort to customize. This makes using old versions economically impractical.

Keep up with the times!

CS-Cart upgrade workflow

Get the latest CS-Cart version with your products, images, logo, banners, options, features, categories, users, orders, pages etc.


Step 1 - Database transfer

Latest versions of the CS-Cart platform are not compatible with earliest versions. That is why we follow this scheme during database upgrade. Before we start working we make a backup copy of your online shop and carefully copy it to the test server to preserve all data.


Step 2 - Upgrading custom modifications

Starting with version 3.х, CS-Cart has new software architecture that is based on a new enhancement approach (API). The source code of most PHP and template files has been rewritten. So the most of modifications developed for earlier CS-Cart versions will not work in new version. When upgrading modifications we examine functionality of each of them and develop them from scratch using the API of latest CS-Cart, which guarantees smooth and quick upgrade to the future versions.

Step 3 - Front works

After upgrading a web shop, its old design usually requires upgrading too. If you use unique design templates, we will adapt them to the new version or integrate them anew. We also provide design creation services so we can help you create a unique design for your online shop platform.


Our clients

Fantastic bunch of people to work with!

We have been working with Simtech over 2 years now and it has been a great journey. Team help us on achieving our milestones without any hitch. I see Simtech Dev as a long term partner for us.


Dhamindu Don

General Manager at UNIXMO

Simtech Development is always fast and in time. They solved every problem without an extra-budget.

Features and design were very important for us when we were choosing the platform. In Multi-Vendor, the admin-panel is easy to use, you can change the look and feel without coding, you can change many, many things from the admin panel such as the design or the commission rates and so on. And the price: the cost-value ratio is fantastic. So, at the end I would chose it again


Gunther Windler

CEO Kayamo

I appreciate it very much

I appreciate it very much because I work with my clients in a similar way. Summing up, I am very happy and thank you for that.


Mariusz Szymanowski

President GRUPA NOVA SP. Z O.O.

I chose SIMTECH because they are very professional compared with other vendors

What I liked most was their patience and the extra mile service that they provide. I’ve tried other vendors in the market, but seriously… they are not worth it. I still prefer SIMTECH overall.




Fantastic bunch of people to work with!

So first of all, I really just feel safe as I know I can always lean back on Simtech and my own relationship manager here at Simtech when I have issues with my website or server. For someone like me who has no clue about coding nor hosting, this is brilliant. Moreover, this allows me to really focus on my main business. Also, since I moved from my own hosting account to Simtech’s Cloud Hosting, a lot has been made easier for me.


Sophie Brunner

CEO Urbankissed

Their knowledge about our e-commerce solution was very impressive

The only integration that 100% worked and reached our expectations of security was Simtech Development’s one. This development was one of the best decisions that we made, the sales increased by 150% in one month alone! In the next 3 months, we sold almost 80% of what we sold for the last year!


Yamir Palma

CEO of Faly Music

The result is exactly as planned

Simtech is the company that has integrated a new design on our website, created by our designers. The result is exactly as planned, Simtech's professional team was transparent, reliable, responsive, flexible and fast in their work, for which we are immensely grateful.


Enisa Palamar

CEO of The Real Luxury

I have no experience in web development but wanted to build a marketplace

After doing some research, I decided to hire a freelancer to make some customizations for my MVP. This was a terrible experience. It was difficult for me to find developers who knew how to make the customizations I wanted and Simtech knew how.
