About Bitrix24. I can only say one thing about the websites — it needs improvement! Although there are ready-made solutions and modules, they still don't work correctly. Often, I have to spend a lot of time refining certain elements because changes don't save properly: they save, but with incorrect parameters (color, font, size — not what I wanted). The Marketplace has appeared, where you can subscribe and purchase add-ons for creating stores, but even these add-ons function with errors. There is also the possibility to create your own design for blocks (similar to zero blocks at *********), but here too there are difficulties: when adding elements, they are placed chaotically instead of in the right spots. The only plus is the integration with CRM and the ability to work within one system, as well as compatibility with other Bitrix24 services. My rating is 2 out of 5!
