It's a bit different for each Dynamics product and doesn't include AX.
For NAV you get either ""BE"" Or Business Essentials or you get AM or Advanced Management. In NAV, AM gives you many of the manufacturing components, intercompany and consolidations, full CRM (Nav's built in CRM) vs. just contact management etc.
You might say, why wouldn't everyone choose AM? Because the maintenance is based on the SLP and BE is $2,200 per concurrent user while AM is about $3750. In a way its a little like Sage's move ot subscription pricing. It's to get more customers paying annual maintenance.
With NAV there are still some optional components. If your a manufacturer for example, it doesn't include Kanban, MRP, kitting an a bunch of other stuff. We are finding that a real 5 user deal for a manufacturer is more like $15k, but that's alot cheaper than the normal 25-30k
It also gives us an excuse to the prospect not to do on-site demos since the software margin is so small.
Relative to MAS, you get pretty much everything MAS has +
Finite capacity scheduling
A sophisticated Dimensional based GL architecture
Full multicurrency
multi-bin
WMS (with optional costs for hand helds
Shop floor control
3 step warehouse transfers
Something akin to Jobops's Component Exception Manager
Available to promise, capable to promise
container tracking
true landed cost management
Field and bench service management
Fully same code base CRM for customers, vendors and prospects
With crm full server side synchronization with Exchange
Bulletproof SQL with full commit-rollback and versioning (i.e. no data corruption other than bad programmers)
And probably a ton more stuff I can't think of off the top of my head.
