Go to a big IT conference and ask how many people use ConnectWise. The majority can't be wrong.

It can be overwhelming for small companies
The north american cloud can be slow sometimes, they know about it, they are rewriting the program so it operates faster but it's a big project. so they release bits and pieces at a time (weekly)
If it isn't in ConnectWise it didn't happen, yeah it adds a bunch of work to your day. Junk in junk out.

don't buy the on-premise edition, you won't be able to keep up with the updates.
They update so frequently I have to update my QuoteWerks frequently,

There are a lot of features on this platform that would be of interest to MSP's. The time entry, calendar ease, global search. Asset and configuration and contact addition is great.

One thing i strongly dislike about Manage is that you can't add rich text to the ticket entries not drop images which make things easier for tech just picking up on tickets.

ConnectWise Manage has a wide birth of functionality. It has 80% of what an MSP needs to manage its service offering. We used the product for 3 years. We used it for ticketing, project management, product inventory, lead tracking, marketing, and client communications. The product's maturity lead us to use many integrations with other services and products.

It's so hard to pick just one thing that I liked least. The company itself was my biggest issue. The sales team had no sense of ethics and resorted to lying in order to make a sale.
If ignoring the deplorable ethics of the company, the product itself has innumerable flaws. The one thing we could not get past was our struggle to regain the efficiency we had prior to using ConnectWise Manage. We took an 30% efficiency hit using ConnectWise Manage. Previously we used MaxFocus Service Desk, and since moving away from ConnectWise we use SolarWinds MSP Manager. We immediately regained our lost efficiency and have maintained it for the past 6 months.
ConnectWise Manage had great automation, but the number of clicks and manual steps required to take advantage of it were not worth it.
