I have been the usage of Bitrix24 for many years now... every so often for little things, a few different times only to check out and understand how the product has been changing over the time. However, I think it's a real hidden jewel for me, and I will start using it more regularly. This CRM delivers the whole thing in one package, and I will run my whole company almost entirely on it. CRM, possibilities, projects, Intranet, Workflows, phones, Unified Communications, and so forth. If this piece of software adds accounting and financials to the programs, it'd be a one-stop solution for every entrepreneur.
I suppose the most useful function I've seen on Bitrix24 is the fact that CRM strategies are genuinely customizable... True, most CRM structures permit you to customise small things like the field name, a few behaviors, and some different little stuff. However, Bitrix24 helps you to switch the whole thing healthily from single order processing to a multi-language commerce operation that is exceptionally clean, and in case you want to try distinctive angles, you could create multiple pipelines with one-of-a-kind configurations...
As I said before, I have tried Bitrix24 and more, also worked with most of the best-known ones (from Microsoft to Zoho to NoCRM,) but because I've rediscovered the new capabilities and functionalities from Bitrix24, I'm no longer looking for a new one.
