Company operations as a service?

I am sure someone had to already solve this. Let's say you have your fresh LLC and now yo have to setup basic operations infrastructure:

1. Company domain and website
2. Emails
3. Place for sharing documents(Google docs, Dropbox)
4. Communication channel (Slack, Discord)
5. Project management tracking (Trello, Jira, Monday...)
6. Other things like company password management, finance tracking, payment processing

We managed to do this, but it had few problems:

• we had to figure out sometimes by error what tools we actually need, which meant trial and error and often cleaning up a mess
• bit hard to maintain, even basic information is split between different apps
• we pay for everything separately would hope for some package price
• had to setup system for communicating between moving parts , which I was able to do mainly because I am technical so I was able to either setup Zapier or if necessary write simple scripts to automate

I pretty much would be able to create simple flow where you pick from best services and sell that. Wouldn't cover every case obviously, but should cover a lot of companies (especially if I pick a decent niche)

How did you deal with this, have you seen this solved and if not what do you think I am missing here?
