I would try FreeAgent (see available features). Apart of standard plans, they've also version for accountants, so it can handle multiple entities with loads of features.
Otherwise try some alternatives such as:
QuickBooks app (not online which is a bit limited),
Sage, both should support multiple entities as well.
Have a look at Money Manager Ex. I've been using it for quite some time now and I totally recommend it.
Here is a quick description taken from its web page:
Money Manager Ex is a free, open-source, cross-platform, easy-to-use
personal finance software. It primarily helps organize one's finances
and keeps track of where, when and how the money goes. ...
OpenStreetMap is a map created by a community. The map data is available gratis.
That map is not only available as graphics, but also the raw data. Thus, you can basically query everything. There is an API (a programming interface) called Overpass API, which lets you do that. However, you should understand what you're doing, so please read that page as much ...
QuickBooks is a big name tool in the United States which does all of this and has a French version https://quickbooks.intuit.com/fr/, but I'm not sure if the French one does "Pays and pay slips"
To fill that other piece, potentially a big name provider like https://www.fr.adp.com/
I'd recommend making sure that anything she considers has been around at ...
I tried GNU Cash and Wave. My main problem with Wave is that they own my data. I want my data on my pc. Which is where GNU Cash shines. However, there are basic usability issues with both. To handle Sales Tax is not too bad. But purchase Tax is a nightmare. Every transaction has to be split in GnuCash, and Wave is not much better. I tried a few ...
I found the absolute best budget app a few months ago and I bet it will work great for your friend. I have tried many different apps for Windows and Android looking for something as close to Quicken as I could find, but one that was either free or really inexpensive. One of the most important features to me, in addition to categories and repeating payments (...

Its called SSO or single sign on. While I'm not a dev, I'm a very happy user oauth2 (I use it to log in on this site). Dosen't seem quite perfect here cause of onedrive.
For corporate use, I've known of people tying things into active directory - there's plugins for various bits of software, like wordpress, though with the breadth of this question you'll ...
Ledger meets your requirements.
"in Linux" — Check.
"simple to use" — Check. Type your transactions in a simple format with a text editor, then type commands like ledger reg to show a register or ledger bal food to show the total amount attributed to accounts with "food" in their name.
"able to input all transactions manually" — Check, with a text editor.
You Need A Budget (YNAB) should have what you are looking for.
It is very simple to use, and offers free online classes to help you get started. It is much easier than GNU Cash.
Transactions can be entered manually. (That is how I use it.) It can connect to a bank and download transactions automatically, but I don't think that feature is ...
Data extraction from PDFs is not necessarily a trivial solution; however, it's a good time to have this problem in that there are quite a few options based upon what "type" of user you are. Probably the best overall software package (which I've used before to great success) is Tabula:
... it's open source, and I'm a full stack ...
A useful accounting software for small businesses is Billbeez.

Online (cloud-hosted) accounting software for your small businesses.
I think they all offer on-line access, software and mobile apps.
Personally I would recommend FreeAgent, as I ...
