>How are they more "legit" than ledger? Is it widely used? Can you get staff with a couple years experience using ledger? Will accounting staff be productive using the interface? Does it cope well with multiple simultaneous users? Is it compatible with other software? Can you get local support? Can you export/import to other packages? Are the fringe case glitches known? All these things matter with finance software,…
To add to dragonwriter's answers: > Can you export/import to other packages? Ledger only reads data you stored in text files . You can't really get much more flexible than that. Give me another package's installation and a weekend, and I'll throw you a compatibility layer. Can you say the same about those other packages?
Cool. Now do the same in a commercial context without a HN hacker on standby? Say with a mediocre skill unmotivated IT department. Sane management takes one look at it and rather pays the 100 USD for a commercial package than dealing with their mediocre IT implementing some ledger/VCS/HN special edition. Thats 100 USD very well spent...
