In the land of all the self hosted solutions. What are your best practices / options for business and general admin tasks?

So far we are thinking of setting up a NAS, Paperlessngx for document scanning, FreePBX for phone system, they have accounting software and employee time tracking software. Planning to use nextcloud, running on Proxmox including backups to NAS, with tailscale for 2 people to get in from outside, photoprism for photo storage, portainer.

The goal is a simple, clean, hands off, ways to cut down, centralize the general business work flow. This is a from scratch build and start. All options welcome, the point is to explore ideas. Full production environment for a small business. 1 or 2 office people, 1 to 10 employees. Using a gaming rig mid high end specs which is way overkill for this setup but it might grow depending on this post.

I am looking to FOSS-ify a local business. It's a service based business, that also does manufacturing which is growing rapidly to overtake the service side it seems this is their goal anyhow.

This is our time to shine! To show how far we have come and what we can now do! An exciting project.
