An ERP business case is useful when every assumption has a source. The goal is not to promise a percentage; it is to compare the cost of staying the same with the investment and expected benefits of improving the operation.
1. Calculate the current cost of operating
Include current tools, consolidation time, rework, errors, tied-up inventory, late closes and opportunities lost because information arrives too late.
Create a baseline
2. Estimate investment and adoption cost
Consider subscription or licenses, implementation, migration, integrations, training, support, process changes and the time your team will dedicate to the project.
Compare scenarios
3. Measure the result after implementation
Define indicators before starting: close time, inventory accuracy, response time, complete orders, rework, adoption and data quality.
ROI is learned

Start with the Grupo GDS ROI calculator and then validate the assumptions with a process review. The strongest financial decision grows from operating data people can understand.
