Under "Service cost" it could use an option for "one time purchase fee". Obviously that is going to create special cases for the "amortizations" output

Cheers, a few people of suggested this. As you note, it rather depends on the amortization period.

At the moment it assumes 1 year for training costs to be amortized over, so I guess one-time purchase would be similar - configurable assumptions (or at list, visibility into the assumptions) is on the list of things to do.

Yep... conceptually, you want to quantify, recurring gains, recurring costs, one-time gains, and one-time costs.
