Monarch Inventory Services provides warehouse inventory services in St. Louis, MO, to distribution centers, 3PLs, and plants on both sides of the river. Our auditors are direct hires and lift certified, and a dedicated project manager stays on site until your numbers reconcile. Crews trained on retail store counts fall apart around narrow aisle racking and WIP staging, which is why we run a separate platform built for warehouse and distribution environments.




St. Louis is not one warehouse market. It is a bi-state market, and the counting problems change depending on which side of the Mississippi you are on.
Plenty of operators run a Missouri building and an Illinois building under one P&L. We staff and schedule both as one project, with one consolidated number at the end.
Six Class I railroads, four interstate mainlines, and the nation’s most efficient inland port district by tons moved per river mile mean rail, barge, truck, and parcel all feed the same building. That is how unit of measure errors pile up: pallet versus case versus each, inner packs counted as cartons, rail released quantities never confirmed.
Newer product around Edwardsville, Pontoon Beach, and the I-70 corridor out toward O’Fallon and Wentzville runs 36 to 40 foot clear with narrow aisle racking. Older inner ring and North County space runs low clear with mixed floor stack. Different team sizes, different equipment, different day plans.
Aerospace in Berkeley and Hazelwood, auto assembly in Wentzville, food and ag across the region. Serial, lot, and date code capture is a standard request, not a special one.
Inventory tax isn’t what drives counts in this market. Here, the trigger is a fiscal year-end audit, a lender, a system conversion, a WMS accuracy problem, a customer SLA, or a facility move. Which one it is changes how we scope the job.
Wall-to-wall counts for fiscal year-end audits, lender and customer requirements, facility moves, and system conversions, planned around your shutdown window. We bring our own team, equipment, and supervision, so your staff is not pulled off normal work to count. Output is reconciled and formatted for upload before we leave the site.
Recurring counts that run alongside operations instead of stopping them. Useful when location accuracy drifts between full counts. We can run the cycles ourselves on a set schedule, or build the program and train your team to run it, depending on how much you want in-house.
Certified CubiScan technicians for a new building, new SKUs, or dimensional weight charges on parcel. Turnkey including rental and delivery, or support for a plan your team runs. Captured data comes back in the format your WMS, slotting tool, or parcel rate agreement needs.
Inspection and verification when defects or mislabels are reaching customers, plus shipping and receiving support through peak. Work can be sorting, rework, repack, or 100 percent inspection of a suspect lot. We document what was found and what was corrected so you have something to send back to the supplier.
When the count keeps coming back wrong, the count is a symptom. Our Six Sigma-certified team finds the root cause and builds the turnaround plan with your leadership. Common findings are receiving and putaway process gaps, unit of measure mismatches, and location discipline, all of which show up as variances long before anyone calls them a process problem.
Data is only useful if it lands where your team already works. Our capture platform is configurable, so we collect exactly the fields your WMS expects: SKU, quantity, location, lot, serial, date code, whatever your process requires. We format the output to your upload spec, whether that’s SAP, Oracle, Manhattan, or something homegrown. We adapt to your system rather than asking you to adapt to ours.
Live dashboards and data feeds let your team watch progress and variances during the count. Variances get flagged and researched while the project is running, not compiled into a spreadsheet you inherit on Monday.
One thing worth raising up front: if your WMS and your physical shelf have been disagreeing for a while, tell us. It changes the recount and verification approach we build into the quote.
A short call on the building, the driver, and your timing, then a questionnaire covering SKUs, locations, storage types, clear height, equipment, file specs, and site access. Multi-building operators tell us here if Missouri and Illinois count the same weekend.
You get team size, project dates, process, and cost in one number. No line items appearing later.
We walk the site or review your layout, confirm staging and housekeeping expectations, agree on the cutoff, and align with your safety manager on badging, PPE, and lift access.
Our PM and team run the count on your schedule, including weekends, nights, and shutdown blocks. Your team watches progress live rather than waiting.
You get the formatted file for your system plus variance detail. If we saw process issues while we were in the building, you hear about those too.
Monarch teams travel to facilities across the metro on both sides of the river, including:
Missouri: St. Louis City, Earth City, Hazelwood, Berkeley, Bridgeton, Maryland Heights, Chesterfield, Fenton, Valley Park, Arnold, St. Charles, O’Fallon, Wentzville, and the wider North County and St. Charles County corridors.
Illinois: Edwardsville, Pontoon Beach, Granite City, Collinsville, Troy, Caseyville, Highland, and the Metro East industrial parks along I-255 and I-270.
If your building is not on this list, it is still very likely in range. Ask us.
Also serving St. Louis: Healthcare Inventory Services and Retail Inventory Services.
Pricing depends on SKU and location counts, storage types, clear height, and how tight your window is. We quote each project individually after a scoping conversation and give you one all-inclusive number that includes team size and dates. There is no charge for the quote.
Yes. Missouri and Metro East Illinois buildings can be scoped under a single project so your consolidated numbers land together. Tell us during scoping whether the sites need to count simultaneously or in sequence.
It comes down to SKU count, location count, and how much of the building is high bay. Large buildings are commonly counted over a weekend or a scheduled shutdown block with a larger team rather than stretched across weeks. We size the team to hit your window, and that estimate is locked into your quote.
Not always. A wall-to-wall physical count usually needs a freeze or shutdown window, but a cycle counting program is designed to run alongside normal operations. Many operators run cycle counting through the year and reserve the full count for fiscal year-end.
Yes. Our capture platform is configurable, and our teams have worked across a range of WMS and ERP environments, including SAP inventory management. We format the output file to match your upload requirements rather than handing you raw data to clean up.
No. Everyone on your project team is a direct hire of Monarch. Temp labor brings inconsistency and turnover into a project where accuracy is the entire point.
Yes, and it is common. Post-peak January and fiscal year-end are the busiest windows across the industry, so booking early gives you a better shot at the exact date you want.
