Mercurio CMS can help if you are planning to advance your business and online store, increase the number of products, want to get access to 9 e-commerce platforms at once. Prom is suitable for a relatively small number of products and if your audience is exclusively on this service.

Our CMS opens up many capabilities for online sales. By purchasing a license, you become the owner of an online store and can develop it without limits: add integrations, new blocks, unusual design or create new features. The system updates are free and planned. Prom seems to be a cheap and simple solution. However, you might not realize, that the service charges additional commission for purchases of your products and takes a surcharge for showing the items in catalog.

Mercurio CMS also has an option of products placement on Prom. Furthermore, you will get your personal online store with more capabilities than the SaaS platforms provide. Let's compare these systems to ease your choice.

General comparison

Mercurio CMS

Mercurio CMS is a complete e-commerce solution with a ready-to-use online store and management system.

The CMS-based online store is fully owned by you. It can be developed without restrictions, both with our team or with your developers. You can even sell the e-commerce platform if you wish. 


Prom is a SaaS solution on which you can place your products. You get a limited set of features. In essence, this is a powerful bulletin board, not a full-fledged website for trade.

SaaS (soft as a service) means that you rent space on the e-commerce platform, but will not become a full-fledged owner of the online store based on Prom. You cannot pick up the website, data, or refine the solution.

Our reviews

I had a good experience developing an online store for us as clothing manufacturers. The team recommended to start the basic version of the online store at the beginning, and then, after the project starts to earn, to implement all sorts of chips that I wanted. I agreed and did not regret it. I am still developing my project. Everything suits. I recommend.

To create the site of the publishing house "White Owl", I turned to the Mercurio CMS team, as I had worked with them before and knew that if they do - everything will be ok. This time I had time and budget constraints, and the guys for a month without pain and difficulty made us a good working site that closes all the tasks we need. Also, what is important for me personally, it is easy and interesting to work with people in this company.

Christina, publishing house "White Owl"


I have been working with this company for a long time. He has done many different projects in the field of e-commerce and online sales. We have worked for a long time, everyone is comfortable, we understand each other without unnecessary bureaucratic red tape. I can advise without a doubt.

Igor, online store Bamboo


Working with the team's specialists is quite satisfactory. Everything is realized very quickly and all my wishes and ideas are understood without long explanations. I have a lot of developments in the project for my specific processes and needs.
