The demo of MODS comes for free and may be used for ever and ever, but it's limited to 25 registered network which is found reasonable for extensive testing, but not enough for a commercial usage.
For a version without restrictions, please contact Bergatrollet
MODS has taken many hundreds of hours to develop, and the potential sale is only a handful of operators. This will give you an indication of the initial price level. MODS will also come with an annual running fee for servicing the software, but on the other hand updates to the current revision of MODS will be complimentary.
Operator specific development and report building, can be provided and will be charged by the hour.
Specific levels of initial purchase fee, annual service fee and hourly consultancy fee will be subject to negotiations.
Donald Docs (or whatever the final version will be called) is a complimentary addition to MODS. It cannot work independent of the MODS database in it's current shape.
