Yeah, I don’t know. I know that there are softwares specific for invoicing but I’ve never used one, nor did I use to send too many invoices. Most of the time I was an employee, doing some other freelances, so it wasn’t too much to keep track.

I used Inkscape because I was more used to it, working with graphics most of my life. LibreOffice is probably easier. But I don’t know how that’s supposed to be done with proprietary softwares either.

Hopefully someone with more experience on this can help him.

What software do you use?

I worked with 3D for decades and Blender replaced almost everything. The performance is actually better on Linux. I personally use Linux mint, but regarding software it barely matters what distro you use nowadays.

But support, compatibility, ease of use can vary a lot. I haven’t used another distro for many years so I can’t say much.

If you rely on autodesk and adobe stuff you will probably suffer. But personally I would say it’s deserved because there are not a lot of companies more evil than them. The sooner you start trying alternatives the better.

Invoicing I just used inkscape but it’s not great. Be prepared to make some sacrifices, but it’s all worthy to get rid of microsoft.
