WMS Selection & Implementation Services
Choose the right warehouse management system, implement it without a peak-season meltdown, and get the productivity you paid for. SIS consultants have run warehouses and delivered tier-1 WMS programs across retail, 3PL, and distribution.
- Infor WMS implementation partner
- Manhattan program experience
- Selection through stabilization
The software is rarely why a WMS project fails. The implementation is.
Tier-1 warehouse management systems are capable products. Projects stall because requirements were written by people who do not run the floor, because configuration fights the way the building actually works, and because testing only covers the happy path. The result is delayed go-lives, shipping disruption, and a system the team works around.
SIS approaches WMS selection and implementation from the operation outward. We define requirements from real order profiles, labor models, and exceptions; run a vendor-neutral selection when you need one; and lead or support configuration, integration, testing, training, and cutover so the warehouse keeps shipping.
We are an Infor WMS implementation partner, and our team has delivered Manhattan Active Warehouse Management programs and robotics integrations. That breadth matters during selection: we can tell you where each platform fits, and where it does not, from delivery experience rather than a brochure.
When teams bring us in.
Your WMS is eight or more years old
Upgrades are painful, support is thinning, and new requirements like omnichannel or automation are hard to bolt on.
You are moving off spreadsheets or an ERP module
Growth has outpaced basic inventory tools and you need directed putaway, waves, and real-time inventory.
Selection is stuck
Demos all look the same, the RFP is a feature checklist, and nobody can compare total cost and implementation risk.
A go-live keeps slipping
The project has been postponed, business and IT disagree on readiness, and confidence is gone.
Post-go-live productivity never recovered
Units per hour are below the old system, workarounds are spreading, and the vendor says it is working as designed.
Automation is on the roadmap
AMRs, sortation, or goods-to-person systems need a WMS that can orchestrate them, and integration is unclear.
End-to-end WMS consulting, or just the part you need.
Requirements from the floor up
Order profiles, SKU velocity, exceptions, labor model, and integration needs translated into requirements vendors cannot hand-wave.
Vendor-neutral selection and RFP
Shortlist, scripted demos built on your scenarios, scoring, reference checks, and total cost of ownership comparison.
Implementation leadership
Program management, design workshops, configuration, and decision-making that keeps scope tied to business value.
Integration with ERP, OMS, and automation
Interfaces to ERP (including IBM i based systems), order management, carriers, and material handling equipment, designed and tested end to end.
Testing beyond the happy path
Scenario-based test scripts that cover exceptions, edge cases, and volume, so the first peak is not the first real test.
Training, cutover, and hypercare
Role-based training, cutover planning, and on-site go-live support until productivity is back at or above baseline.

Assess
Baseline the current operation and systems, and define what the new WMS must do and what success looks like.
- 02
Select and design
Run selection if needed, then design processes and configuration around how your operation should run.
- 03
Build and test
Configure, integrate, and test with real data and exception-heavy scripts before any site goes live.

Go live and sustain
Phased cutover, on-floor hypercare, and KPI tracking until gains are locked in.
MAWM implementation recovery, 13 fulfillment centers delivered
$36B medical supplier. Recovering a stalled Manhattan Active Warehouse Management rollout and turning it into a scalable, multi-site deployment engine.
SIS realigned operations and IT, revised configuration to match how the sites really ran, and built thousands of exception-focused test scripts. Customers returned to pre-implementation performance within a week of go-live.

WMS consultants who have worked the floor.
Operational credibility
Our consultants average more than 15 years in warehouse operations and systems. They design for peak, labor, and exceptions.
Platform breadth
Infor WMS partner with Manhattan and robotics delivery experience, which keeps selection advice grounded and honest.
Integration depth
Our IBM i practice means legacy ERP integration is in-house, not a gap discovered halfway through the project.

WMS selection and implementation questions
What does a WMS consultant do?
A WMS consultant helps you define requirements, choose a warehouse management system, and implement it. That includes process design, configuration, integration, testing, training, and go-live support. An independent consultant also protects you from scope and design decisions that suit the vendor more than your operation.
How long does a WMS implementation take?
It depends on scope, number of sites, integrations, and automation. Typical SIS warehouse engagements run six to twelve months, delivered as a phased rollout that protects day-to-day shipping. Multi-site programs can accelerate once a repeatable deployment model is in place.
Do you only recommend Infor WMS?
No. SIS is an Infor WMS implementation partner, and we also have Manhattan Active Warehouse Management and robotics integration experience. During a selection we evaluate the platforms that fit your requirements and budget, and we will tell you if Infor is not the right fit.
Should we replace our WMS or optimize the one we have?
Start by finding out whether the system is truly the constraint. Many operations recover significant productivity through configuration, slotting, and process changes. Replacement makes sense when the platform cannot support your growth, channels, automation, or support requirements.
Can you rescue a WMS implementation that is already in trouble?
Yes. Project recovery is a large part of our warehouse work. We assess readiness, realign business and IT, revise configuration where it fights operations, and rebuild testing so the next go-live date holds.
Do you integrate a WMS with an IBM i or AS400 ERP?
Yes. Our IBM i practice builds integrations between warehouse systems and IBM i based ERP and merchandising platforms, using APIs, message queues, and file-based interfaces where appropriate.
