When should a business hire an inventory optimisation consultant?
Consider an independent review when shortages and excess stock persist together, planning parameters are difficult to justify or teams disagree on the numbers. Start with a defined decision and an agreed baseline—not a promised percentage saving.
Look for decisions that remain unresolved
Repeated expediting, slow-moving stock and unexplained differences between planning reports can indicate a need for deeper analysis. These signals do not prove that consulting is necessary; first establish whether the cause is known and whether your team has the time and capability to address it.
External support can be useful when a network or production planning change requires a focused review, or when an independent perspective would help reconcile competing service and inventory objectives.
Agree what success means
Define the materials, locations and processes included in the engagement. Agree which measures represent availability, stockout exposure and inventory investment, and how each is calculated. Compare outcomes with an agreed baseline and note changes in demand or operating conditions.
Avoid accepting a universal savings promise before the data has been reviewed. An appropriate recommendation may reduce some stock while increasing protection for a critical material.
Prepare a useful starting dataset
Gather material and location-level usage, stock balances, open orders, lead-time history and current planning parameters. Add order constraints, stock ageing and operational priorities where available. Data gaps should be identified explicitly rather than concealed behind precise-looking recommendations.
A first review can start with existing exports; replacing an ERP system or establishing live data connections is not automatically required. Agree appropriate access and confidentiality arrangements before sharing company information.
Ask about validation and handover
Ask how proposed policies will be tested, who approves live changes and how planners will maintain parameters after the review. Look for documented assumptions, practical exception handling and a staged rollout rather than a report with no owner.
Replentia's focus is data-led inventory policies, material replenishment, operational supply risk and planning dashboards for European businesses. Matt's experience comes from employee roles in supply chain planning and data analysis, including life sciences and data centres; this is not a claim of completed independent client projects.
