ERP business case: separate cash savings from capacity
Build an ERP business case using documented baseline work, measurable outcomes, explicit benefit owners, and a transparent distinction between cash and capacity.
Turn requirements into comparable quotes, scenarios, and acceptance tests.
A useful ERP buying process turns a business problem into evidence that a solution and delivery plan can meet it. This workbook follows that process from requirements through demonstrations, quote comparison, migration planning, rollout, and the business case. Start with the buying checklist to identify the approval gates and people who need to participate.
Use the quote worksheet to make scope differences visible before comparing totals. Build a budget with explicit inputs instead of copying a market average. Bring operating exceptions into demonstrations, and retain those scenarios as the basis for acceptance tests. Plan migration and rollout around the work your own team must perform, including reconciliation, training, and temporary coexistence.
The examples are deliberately illustrative and the worksheets are general procurement guidance. Replace assumptions with your own measured baseline, written proposal, and approved requirements. Have finance validate material monetary claims and have technical and legal owners review matters within their expertise. A completed checklist is an index to evidence, not a certification. The final decision should be understandable to a reviewer who did not attend the sales meetings.
