We've been using Bitrix24 in our company for about a year. The platform is truly comprehensive: it has CRM, task management, storage, and chat all in one place. The Business plan offers enough features for medium-sized businesses. Task automation and funnels help us meet deadlines. On the downside, the platform can be sluggish and slow, especially during peak hours. Customer support sometimes takes a long time to respond, and the subscription price is quite high for small teams. The interface requires time to get used to, but once set up, it works efficiently. It's a good choice for medium-sized businesses, but be prepared for an adaptation period.
