Of course it'll run fine on other distros . .
. . but business management software has "idiosyncracies" which require help from the publisher. The problem is at least as bad in small business as in midsize and up.
An example is a client who refurbishes Nortel telephone systems. He uses an accounting program from Data Pro (Infinity Power) with custom forms and other minor mods. Moving to a different package would be traumatic for the company.
When it was necessary to migrate from the DOS/Network version (the new 32-bit recompile to support XP/2000 was way too slow compared to the 16-bit version), we set up the Linux host version with terminal emulation. The client already had been using a Linux Samba server running Caldera Linux.
When Data Pro found out we were on Caldera, they flat out refused to honor a paid-up support contract because it wasn't on Red Hat.
Software companies will grasp any straw to deny support. I've even had them deny support for database problems because we were using a different terminal emulator than they recommend. They said that had to be the cause of the data indexing problem.
