Atlassian tools for a client like mine (hundreds of employees) can easily cover the expense of internalizing it. It's Jira plus confluence mostly, it's not rocket science.
And that's just atlassian.
Start adding stuff that costs many many many yearly salaries (special software for managing inventories and warehouses) it starts making sense to prototype alternatives internally.
I came to the conclusion that if it's not Teams/SharePoint or the moat is on the extreme legal complexity side (e.g. payrolls), you can at least think of building an alternative that is good enough without needing to be perfect.
