Your stockroom tracks lots and serials by hand because the ERP add-on only counts boxes
A custom warehouse management system for a Sunnyvale hardware or biotech operation, serial and lot tracking, kitting, controlled storage, runs $70k to $150k over 4 to 7 months. Manhattan-class WMS targets giant distribution centers; ERP (Enterprise Resource Planning) add-ons just count boxes. Neither handles serialized hardware, lot-tracked biotech materials, and kitting for builds the way a deep-tech stockroom needs.
A Sunnyvale stockroom isn't a big-box distribution center and it isn't a simple parts bin. You're managing serialized units that customers and regulators trace, lot-controlled materials for biotech where expiry and chain-of-custody matter, and kitting where a build pulls 200 components into a single work order. The ERP's inventory add-on counts boxes and calls it a day. Enterprise WMS like Manhattan is built for Amazon-scale fulfillment and priced and scoped accordingly.
So your stockroom team tracks serials and lots in a spreadsheet, builds kits from memory, and reconciles against the ERP at month-end. For a biotech company, a lot-tracking gap is a compliance problem, not just an inconvenience. For a hardware company, a serial-tracking gap means you can't trace a field failure back to its build. The middle ground, a WMS that fits a deep-tech stockroom, doesn't exist off the shelf.
What breaks first in Sunnyvale
- Serial and lot tracking for hardware and biotech materials is done by hand in spreadsheets
- Kitting (pulling 200 components into a build) isn't supported by ERP inventory add-ons
- Biotech lot expiry and chain-of-custody requirements have no off-the-shelf home at this scale
- Manhattan-class WMS is overbuilt and overpriced for a deep-tech stockroom
The fix: warehouse management built for Sunnyvale, not rented
A custom WMS fits the deep-tech middle ground: serial and lot tracking with full traceability, kitting and pick-pack for builds, controlled and expiry-aware storage for biotech, and bin and location management scaled to a stockroom, not a megacenter. It gives you the traceability customers and regulators require without the cost and bloat of enterprise WMS.
What warehouse management costs in Sunnyvale
| Project scope | Typical cost | Timeline |
|---|---|---|
| Serial/lot WMS with kitting | $70k to $110k | 4 to 6 months |
| Full WMS with biotech compliance + scanning | $110k to $150k | 6 to 7 months |
| Kitting / pick-pack module on existing inventory | $40k to $70k | 3 to 4 months |
The capability list that earns its budget
What we build under warehouse management in Sunnyvale
The engagements Sunnyvale teams bring us most often: inbound and outbound logistics, fulfillment software, 3PL software, warehouse management system (WMS), WMS development and pick pack ship.
Exactly what you get
You get a WMS sized for a deep-tech stockroom: serial and lot traceability, kitting and pick-pack for builds, expiry-aware controlled storage for biotech, barcode scanning, and a clean ERP sync. The spreadsheet that tracks serials disappears. It connects to your inventory management software, your ERP, and your supply chain software so receiving, allocation, and production planning all share one traceable record from receipt to shipped, serialized unit.
How to choose a developer in Sunnyvale
Ask how they handle serial and lot genealogy and how a build kit pulls its components. A vendor who talks only about bins and box counts hasn't built for serialized hardware or lot-tracked biotech. The right partner has scanning-hardware experience and treats traceability as the core requirement. Scope the WMS alongside your inventory management software and supply chain software so the stockroom isn't an island finance has to reconcile by hand.
- !They treat WMS as box-counting; ask how they handle serial and lot genealogy
- !No kitting plan; ask how a build pulls 200 components in their system
- !Biotech compliance ignored; ask how they handle lot expiry and chain-of-custody
- !No scanning hardware experience; ask how receiving and picking work
- !They propose Manhattan-scale tooling; ask why it fits a stockroom
Most Sunnyvale teams pricing warehouse management end up comparing notes on business intelligence (BI) dashboards, lms, internal tools too; the systems share one data spine.

Frequently asked questions
Why won't an ERP inventory add-on work as a WMS in Sunnyvale?
Because ERP add-ons count boxes, while a deep-tech stockroom needs serial and lot traceability, kitting for builds, and expiry handling for biotech materials. Those gaps push tracking into spreadsheets and create compliance and traceability risks. A custom WMS fills the middle ground between a box-counting add-on and an overbuilt enterprise system.
Can a custom WMS handle biotech lot tracking?
Yes, and it's a key reason biotech teams build one. A custom WMS tracks lot numbers, expiry dates, quarantine status, and chain-of-custody, which are compliance requirements, not conveniences. Off-the-shelf inventory add-ons rarely handle these at a startup's scale, leaving a gap that custom software closes.
What does a custom WMS cost in Sunnyvale?
Between $70k and $150k. A serial-and-lot WMS with kitting runs $70k to $110k; a full system with biotech compliance and scanning hardware runs $110k to $150k. Serial and lot traceability is the biggest cost driver, alongside biotech compliance and scanning integration.
Why not just use Manhattan or another enterprise WMS?
Because enterprise WMS like Manhattan is built and priced for Amazon-scale distribution centers, not a deep-tech stockroom. You'd pay for and maintain capabilities you'll never use while still missing some hardware and biotech-specific needs. A custom WMS gives you exactly the traceability and kitting you need at a fraction of the scope.
Does the WMS connect to our ERP?
It should, through a two-way sync so inventory stays consistent with finance continuously instead of at a painful month-end reconciliation. A serious build treats ERP integration as core. Without it, the stockroom record and the books drift apart, which undermines the traceability the WMS exists to provide.

Who can build custom warehouse management software for a business in Sunnyvale?
Digital Heroes builds custom warehouse management software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, so an operator in Sunnyvale gets an assigned senior team rather than a local account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other warehouse management software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
