Own (or someone else's) cloud for accounting (G-DRIVE alternative), the best solutions from your experience?

Question

Document flow

Good afternoon, recently dissatisfaction with the quality of google drive, document synchronization, etc. has increased greatly, we are sitting on a free plan, due to the pandemic we cannot afford expensive corporate cloud subscriptions.
The question arose about finding alternatives according to 3 criteria
1. Synchronization of 1 shared folder on all devices for different accounts (about 6 GB in size)
2. The ability to edit documents on the web in this folder
3. No monthly subscription - free or conditionally free
At hand, hardware on which you can raise your server on ubuntu (I already have experience in deploying a mailer on docker), bind its ip to a domain, for example, or buy vds (which is not very suitable because the amount of space there is not enough at low prices), but if there are free alternatives from companies I will be glad to see (except for OneDrive - it’s still sadder there as soon as more than 3 devices appear)

Answer 1

Good afternoon.
For these tasks, we can offer Owncloud - an analogue of google drive, free, with all the features. Payment - only for renting a VPS.
If interested, write in a personal or on the site, in the chat.
