Compare the cost structure, not a sales pitch.
Six ERP buying models and the questions that make their costs comparable.
These are purchasing patterns, not product rankings. A supplier may combine several patterns in one quote. Compare the same user roles, entities, modules, delivery scope, and time horizon. Published subscriptions do not establish implementation cost.
Select a column header to sort.
| Buying model | Price basis | Useful when | Verify before signing |
|---|---|---|---|
| Per-user subscription | Named users and license tiers | You can map tasks to access rights | Minimum users; full versus limited access |
| Bundled application plan | Apps included in a subscription | Several functions share the same platform | Custom code, hosting, and API exclusions |
| Module-based quote | Platform plus selected capabilities | Scope is defined by business process | Dependencies and mandatory modules |
| Usage-based add-on | Transactions, storage, credits, or calls | Consumption is measurable | Included allowance and overage rates |
| Partner implementation | Fixed scope or time and materials | Delivery work can be specified | Acceptance criteria and change rates |
| Self-managed deployment | License plus infrastructure and operations | You have operational capacity | Upgrade, security, backup, and support ownership |
