Your Ann Arbor warehouse module counts bins and ignores that bin 14 must stay at minus 80
A custom warehouse management system for an Ann Arbor biotech, hardware, or research-supply operation runs $60,000 to $190,000 over 4 to 8 months. Manhattan-class systems and ERP (Enterprise Resource Planning) warehouse add-ons run pick-pack-ship for boxes efficiently. They miss the realities of a research or hardware stockroom: minus-80 freezers, controlled-access zones, kitting for instrument assemblies, and storage conditions that are part of the inventory's identity. A custom WMS manages condition and compliance, not just location and count.
Your warehouse module came with your ERP and it tracks bins, quantities, and pick paths. It assumes a bin is a bin. In your operation, bin 14 is a minus-80 freezer, zone C is access-controlled for controlled substances, and assembling a shippable AV sensor unit means kitting twelve components with traceability. The ERP add-on has no model for any of that, so your warehouse team runs a parallel set of rules on paper and in their heads, and the system's stock picture quietly diverges from physical reality.
Manhattan and similar enterprise WMS platforms are powerful but built for distribution-center throughput, not for a lab stockroom where storage conditions, controlled access, and assembly kitting dominate. The generic add-on that shipped with your ERP was designed for the median warehouse, and a biotech or AV-hardware stockroom is nothing like the median warehouse.
- Storage conditions like cold-chain are part of your inventory's identity
- Controlled-access and chain-of-custody must be enforced in the system
- You kit instruments or AV units and currently do it off-system
- Your WMS stock picture diverges from physical reality due to paper workarounds
- Your stockroom is shelf-stable with no condition or access requirements
- Your ERP's warehouse add-on covers your picking and counting fine
- You don't kit or assemble products from components
- You lack the volume or complexity to justify a dedicated WMS
- Condition-aware locations, so a minus-80 freezer bin is modeled as what it actually is
- Controlled-access zones with chain-of-custody enforced in the system, not on paper
- Kitting and assembly workflows for instruments and AV units with full traceability
- Stock accuracy because conditions and access are in the WMS instead of in someone's head
- Integration to inventory and supply chain systems so provenance follows the part
- Condition and access logic make a custom WMS more involved than a generic add-on
- Hardware integration (sensors, scanners, access controls) adds cost and maintenance
- You take on the WMS that your ERP vendor would otherwise update for you
- For a simple shelf-stable stockroom, the ERP add-on is genuinely sufficient
The honest cost picture for Ann Arbor
| Project scope | Typical cost | Timeline |
|---|---|---|
| Condition-aware WMS for a lab stockroom | $60k to $100k | 4 to 6 months |
| Full WMS with kitting and access control | $120k to $190k | 6 to 8 months |
| WMS layer over existing ERP | $55k to $95k | 3 to 5 months |
Feature priorities for Ann Arbor teams
What we build under warehouse management in Ann Arbor
Digital Heroes builds the full warehouse management stack for Ann Arbor teams. Typical engagements cover WMS development, pick pack ship, warehouse automation, barcode and RFID, slotting optimization and inbound and outbound logistics.
Exactly what you get
A WMS that models your stockroom as it physically is. Concretely: condition-aware locations for cold and controlled storage, access-controlled zones with chain-of-custody, kitting and assembly workflows with traceability, sensor integration, and connections to your ERP, inventory, and supply chain systems. You also get source code and documentation. What you don't get is a bin-counting add-on that treats a minus-80 freezer like a shelf and forces your team onto paper. This works alongside your inventory management software and supply chain software.
How to choose a developer in Ann Arbor
Find a team that asks what conditions and access rules your inventory requires in the first call. If they talk pick paths and bins without asking about cold storage, controlled access, or kitting, they're scoping a distribution center, not your lab. Ask for a biotech or regulated-warehouse reference. A good partner integrates sensors and your existing ERP rather than rebuilding it, and aligns the WMS with your inventory and supply chain systems so provenance is unbroken.
Timeline: what happens, and when
- !They treat every bin as a shelf; ask how cold storage and conditions are modeled
- !They've never built for labs; ask for a biotech or hardware-stockroom reference
- !No access-control plan; ask how controlled zones and custody are enforced
- !They skip kitting; ask how instrument or AV-unit assembly is handled
- !They quote a short build; ask what condition-aware locations and kitting actually take
Teams investing in warehouse management in Ann Arbor usually scope it next to business intelligence dashboards, lms, internal tools, since these systems share data and budgets.

Frequently asked questions
Isn't our ERP's warehouse module enough?
For shelf-stable goods, often yes. For a stockroom where storage conditions, controlled access, and kitting define the work, ERP add-ons fall short and your team compensates on paper. The gap is that condition and custody aren't metadata in your operation, they're core attributes, which generic modules don't model.
How long before a custom Ann Arbor WMS pays for itself?
Payback usually comes from reduced loss of condition-sensitive stock and recovered staff time spent on paper workarounds, often within 18 months. For operations with controlled substances, avoiding a custody or audit failure adds value that's hard to price but very real.
Do we need sensor integration?
If storage conditions matter to your inventory, yes, so condition excursions are caught and tied to affected stock automatically. If your materials are robust, you can omit it and keep the build leaner. The right scope depends on how condition-sensitive your inventory genuinely is.
