Activity based costing model consolidation is a feature of the Gold version of ABC Focus.

Consolidation is a process of combining individual models into one big model. The individual items from each model are retained in the consolidated model. This enables all the activity dictionaries, notes, etc set up for each line to be usable in the consolidated model. The only user input required to consolidate models is the choice of which models to include in the consolidation. The rest is automatic.
The consolidated model is live and can be altered and used just the same as any other model. It can be reported from and reviewed as usual.

If there are multiple models of interest but its preferred they remain as separate entities rather than one consolidated model you can inspect these models side by side by comparing models
