For commercial solutions Version tracker [versiontracker.com] are listing a few, but ratings are low.
If you are looking for a cross platform solution, I instictively turn my head in FileMaker Pro direction. (use to develop touchscreen interfaces with it in the medical field years ago)Like, Paygo is a complete cross platform solution going for 1 700 $ for a multi user licence. It is not listed at version tracker. Some other FileMaker Pro modules (bar code, CC processing etc. ) are available if you feel like messing with them. :)

Their "download demo" page is empty.
