ERP Implementation Cost Estimate

This is a practical guide to building a cost estimate for an erp implementation project — a forecast of the money required to complete the work, adapted to the realities of replacing or deploying an enterprise resource planning system across the whole organisation.

What a Cost Estimate is

A cost estimate is a forecast of the money required to complete the work. For the full concept and how it works in general, see Cost Estimation. On an erp implementation project it plays the same role, tuned to this kind of work.

Why it matters for an ERP Implementation project

ERP Implementation projects live or die on replacing or deploying an enterprise resource planning system across the whole organisation. A well-built cost estimate gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how erp implementation projects drift into avoidable delay and cost.

What to include

  • Labour costs
  • Material/equipment costs
  • Indirect costs
  • Contingency
  • Estimate basis and assumptions

ERP Implementation-specific considerations

Tailor the cost estimate to the risks that most often derail erp implementation projects:

  • Under-estimated data migration
  • Business-process change resistance
  • Customisation over-reach

Example

On a real erp implementation project, the cost estimate would be shaped by replacing or deploying an enterprise resource planning system across the whole organisation. In particular, it should explicitly account for the project’s biggest risks — under-estimated data migration, business-process change resistance, customisation over-reach — rather than treating them as afterthoughts.
