Your ERP's warehouse add-on wasn't built to run a 200-truck day on I-78
An ERP (Enterprise Resource Planning) warehouse add-on tracks bins; it doesn't orchestrate a high-velocity I-78 distribution center. A custom or heavily tailored WMS (Warehouse Management System) for Allentown throughput runs $70,000 to $160,000 over 5 to 9 months.
An ERP's warehouse module and a generic WMS know where stock sits. What they don't do well is orchestrate the dance of a Lehigh Valley distribution center at full throttle: directed putaway, wave picking tuned to outbound trucks, slotting that reflects velocity, and labor management that keeps the floor moving when 200 trucks hit in a day. Manhattan and the big WMS platforms do this, but their cost and complexity assume a far larger operation than most Allentown DCs run.
The result is a floor running on tribal knowledge and spreadsheets layered over a WMS that was really an ERP afterthought. Pick paths aren't optimized, slotting drifts, and labor isn't matched to the wave, so throughput caps below what the building could do. This is the coordination gap that defines the I-78 corridor: the systems exist but don't orchestrate.
Budgeting a warehouse management build in Allentown
| Project scope | Typical cost | Timeline |
|---|---|---|
| Core WMS with putaway, picking and slotting | $70k to $110k | 5 to 6 months |
| Full WMS with labor management and dock control | $110k to $160k | 7 to 9 months |
| Annual support and tuning | $22k to $42k | ongoing |
The case for owning your warehouse management
A tailored WMS orchestrates your specific I-78 floor: directed putaway, velocity-based slotting, wave picking tuned to outbound trucks, and labor matched to the wave. For an Allentown DC, that means throughput closer to the building's real ceiling without the cost and bloat of a Manhattan-class platform. It connects to your ERP, inventory management software and supply chain software so the warehouse is part of one coordinated flow.
- Your ERP warehouse add-on can't orchestrate putaway, picking and slotting
- Throughput caps below the building's potential because pick paths aren't optimized
- Labor isn't matched to waves and the floor stalls under peak truck volume
- Manhattan-class WMS is overbuilt and overpriced for your DC
- Throughput is modest and an ERP add-on keeps up fine
- Your SKU mix and order profile are simple and stable
- A lighter packaged WMS already meets your needs
- You lack the floor discipline to feed a sophisticated WMS clean data

Delivery, week by week
Exactly what you get
A WMS that orchestrates your I-78 floor instead of just listing what's in each bin. Directed putaway and velocity slotting lift throughput, wave picking is tuned to your outbound trucks, and labor is matched to the active wave so the floor doesn't stall on a 200-truck day. It's right-sized for an Allentown DC and wired into your ERP, inventory and supply chain software as one coordinated flow.
How to choose a developer in Allentown
A WMS is warehouse engineering, not generic software, so judge the team on whether they understand slotting, wave picking and labor management. Make them explain how they'd lift throughput on your specific floor and SKU mix. Be wary of anyone pushing a Manhattan-class platform at a mid-size DC; the right answer is a system sized to your I-78 building, integrated with your ERP and inventory.
- Directed putaway and velocity slotting that lift throughput on a high-velocity I-78 floor
- Wave picking tuned to outbound trucks so the dock flows instead of stalling
- Labor management matched to the wave, keeping the floor moving at peak
- Right-sized for a mid-market DC without Manhattan-class cost and complexity
- Integration with your ERP, inventory and supply chain software for one coordinated flow
- A WMS is a large, complex build and one of the priciest projects on this list
- Getting picking and slotting logic right takes real warehouse-engineering expertise
- If your throughput is modest, an ERP add-on or lighter WMS may be enough
- You own the WMS uptime; an outage stops the floor cold
- !They equate a WMS with bin tracking. Ask how they optimize pick paths and slotting.
- !No labor-management plan. Ask how staffing matches the outbound wave.
- !They pitch a Manhattan-class platform for a mid-size DC. Ask what's right-sized.
- !No scan-floor experience. Ask how forklift drivers actually use it.
- !They've never built a WMS. Ask for a distribution-center reference and throughput numbers.
Most Allentown teams pricing warehouse management end up comparing notes on business intelligence dashboards, lms, internal tools too; the systems share one data spine.

Frequently asked questions
Isn't our ERP's warehouse module a WMS?
Not really. An ERP warehouse add-on tracks where stock sits, but a real WMS orchestrates directed putaway, velocity slotting, wave picking and labor management. For a high-velocity Allentown DC, that orchestration is the difference between hitting the building's throughput ceiling and capping well below it.
Why not just buy Manhattan?
Manhattan-class platforms are excellent but built and priced for very large operations. Most Lehigh Valley DCs find them overbuilt and overpriced, which is why a tailored WMS sized to your floor often delivers the orchestration you need at a fraction of the cost and complexity.
How does a WMS lift throughput?
By optimizing pick paths, slotting fast movers for shorter travel, sequencing waves to outbound trucks, and matching labor to the active wave. Those four levers together can move throughput meaningfully closer to what the building can physically handle.
How does it fit with supply chain software?
The WMS runs what happens inside the building; supply chain software manages inbound flow and supplier coordination. They integrate, so an inbound truck flagged early by your supply chain system feeds the WMS's dock and putaway plan. Both work best together.
