WMS Implementation as the Essential First Automation Step
Illustrative scenario based on real deployment patterns. Not sourced from a specific company.
Warehouse Profile
- Warehouse size
- 3,500 sqm
- Staff
- 15 warehouse personnel
- Current state
- Paper-based picking and stock management
- Deployment type
- Brownfield — no new construction
The Situation
The warehouse operates without a WMS. Stock accuracy is below 90%. Management wants to automate but hardware ROI cannot be demonstrated without reliable operational data. External consultants recommend a multi-million euro ASRS, but the foundational data required to specify, justify, and validate such a system simply does not exist.
Automation Approach
WMS implementation with handheld scanners and full barcode labelling as phase one. This establishes real stock accuracy, location-level visibility, and measurable picking performance for the first time. The data produced in phase one makes phase two (hardware automation) possible to specify accurately and justify with confidence.
Expected Outcomes
- Stock accuracy from below 90% to 98–99% within 6–12 months
- Visible picking performance metrics for the first time
- ROI calculation for phase 2 hardware becomes credible and defensible
- WMS investment pays back in 12–18 months through inventory reduction alone
Is This Scenario Right for You?
- Deployment
- Brownfield — minimal infrastructure change
- Budget range
- EUR 80K–400K for WMS licence, implementation, and hardware
- Payback estimate
- 12–18 months on WMS investment
- Primary value
- Data foundation and inventory accuracy
- Prerequisite for
- Any subsequent hardware automation project
Relevant Vendor Types
WMS providers active in European SME manufacturing: Swisslog (SynQ), KNAPP (KiSoft), and independent WMS vendors (Sage WMS, proLogistik, Ehrhardt + Partner).

Why do hardware automation projects fail without a WMS in place?
Hardware automation systems (AMRs, ASRS, conveyors) require accurate, real-time stock location data to function. Without a WMS, the automation system cannot know where goods are, what needs to move, or whether picking instructions are valid. Most automation vendor implementations have a WMS as a prerequisite, and projects that attempt to bypass this step experience significantly higher integration costs and lower ROI realisation.
What stock accuracy is needed before hardware automation?
Automation vendors typically require 98%+ stock accuracy as a minimum prerequisite. Below this level, the automation system generates excessive exception handling — robots dispatched to locations where goods are not present, or picking errors that undermine the claimed efficiency gains. A WMS implementation phase specifically aimed at reaching 98%+ accuracy is the standard approach.
Can a warehouse skip the WMS phase and go directly to hardware automation?
Technically possible but rarely advisable. Some vendors will implement hardware automation on top of an ERP without a dedicated WMS, but this approach typically results in higher integration costs, reduced system performance, and a longer path to ROI realisation. The ROI case for skipping the WMS phase rarely holds up under scrutiny.
Readiness Considerations
- Management must be committed to a two-phase approach (WMS first, hardware automation later) to avoid pressure to skip ahead prematurely.
- ERP integration scope should be mapped early to avoid a late-stage surprise that delays go-live.
- Set a realistic stock accuracy baseline before go-live. The WMS reveals problems that were previously hidden.
Supplier Questions to Ask
- QWhat does your ERP integration require and how long does it typically take to configure and test?
- QWhat is the realistic timeline from contract to go-live for an operation our size?
- QHow does your WMS support future phase-2 automation integration such as AMR task dispatch and ASRS slot management?
- QWhat scanning hardware is included and what are the ongoing licensing and support costs?
Assumptions to Validate
- Current stock accuracy. Most paper-based operations discover accuracy is lower than estimated once scanning begins.
- Inventory carrying cost on the balance sheet. WMS-driven inventory reduction often delivers the fastest payback.
- ERP interface complexity and whether your ERP vendor charges for the integration on their side.
- Training requirement per warehouse staff member. User adoption speed affects time to first measurable ROI.
When This May Not Be the Right Time
- Warehouse processes are not yet stabilised. Automating unstable processes locks in inefficiency.
- Major SKU catalogue changes or a facility relocation are planned within 12 months.
- Lease remaining on the current facility is under 18 months. WMS implementation typically takes 3 to 6 months and then requires time to realise ROI.
