Your Coolstore Has Temperature Zones, Expiry Dates and a Forklift Driver Wearing Gloves. Manhattan Was Not Built for That.
A custom warehouse management system for a Nelson coolstore or chilled distribution facility costs NZ$70,000 to NZ$160,000 over four to eight months. Enterprise products like Manhattan and the warehouse modules bolted onto ERPs are built for ambient distribution centres with stable SKUs and dry conditions. A Nelson facility handles chilled and frozen zones, product with an expiry date, batches that must be picked in a specific order, and staff operating scanners in a five degree room. Those differences change almost every screen.
The pick list says take twelve cases of a product. The forklift driver takes the twelve nearest the door. Three weeks later you write off the older pallet at the back that nobody rotated. That is not carelessness, it is a system that told the driver what to pick but not which one, and every chilled operation in Nelson has a version of this story.
Then there is the physical environment. Warehouse software designed for an ambient distribution centre assumes reliable wifi, a driver who can tap a small screen, and a stable temperature that does not affect devices or batteries. In a coolstore, wifi drops between racking, devices fog and drain, and gloves make small buttons useless. The software fails not because the logic is wrong but because it cannot be operated.
Where the off-the-shelf tools fall short
- Picking by product rather than by batch, so older stock ages at the back and gets written off
- Wifi dead spots between racking that cause scanners to lose data mid pick
- No enforcement of temperature zones, so product ends up in a location it should never have entered
- Stocktakes that take a full day and still leave a variance nobody can explain
Custom warehouse management: what Nelson teams actually get
Build custom when the picking rule is a business rule. First expiry first out, customer specific shelf life requirements, batch integrity for traceability, temperature zone enforcement: these are not settings in most products, they are the operation. A purpose built system directs the pick by batch and location, works offline between racking, and produces a stocktake process a supervisor can run on a Friday afternoon. It sits directly on top of batch inventory, feeds dispatch and freight, and reports into the wider operational system.
Feature priorities for Nelson teams
Nelson warehouse management: the full scope
The engagements Nelson teams bring us most often: warehouse automation, barcode and RFID, slotting optimization, inbound and outbound logistics, fulfillment software, 3PL software and warehouse management system (WMS).
- Write offs from poor stock rotation are a visible cost line
- You operate multiple temperature zones and product must not be misplaced
- Traceability requires batch integrity through picking and dispatch
- Stocktakes are disruptive and variances are routinely unexplained
- You run ambient stock with long shelf life and simple picking
- Your ERP (Enterprise Resource Planning) warehouse module covers your needs with configuration
- Under about 1,000 pallet positions with a small team who know the stock
- You need something running in eight weeks
The honest cost picture for Nelson
| Project scope | Typical cost | Timeline |
|---|---|---|
| Directed picking and putaway for a single facility | NZ$45,000 to NZ$80,000 | 3 to 5 months |
| Full WMS with zones, cycle counting and dispatch verification | NZ$80,000 to NZ$160,000 | 5 to 8 months |
| Multi facility WMS with freight integration | NZ$160,000 to NZ$260,000 | 8 to 12 months |
Timeline: what happens, and when
Exactly what you get
A directed operation: receipt, putaway with zone rules, batch and expiry driven picking, dispatch verification and continuous cycle counting, all running on scanners that work in your building. Plus the supervisor tools for exceptions, because a WMS that cannot handle a damaged pallet or a short pick creates workarounds within a week.
Delivery should include a wifi survey and a hardware recommendation. Warehouse projects fail on infrastructure more often than on software, and any supplier who skips the survey is setting up a problem you will pay to fix later.
How to choose a developer in Nelson
Ask to visit a warehouse running their system, ideally a chilled one. Watch a pick. You will learn more in twenty minutes on a floor than in three proposals. Pay attention to how staff interact with the device and whether they are working around the system in small ways.
Discuss the rollout plan explicitly. A zone by zone or product group rollout lets you learn with limited exposure, and it means a problem affects one aisle rather than your whole dispatch. Suppliers who insist on a single cutover are usually managing their own project cost rather than your risk.
- Directed picking by batch and location, which ends the write off from unrotated pallets
- Scanners that keep working in dead spots because the app holds data locally and syncs
- Temperature zone rules enforced at putaway, so product cannot be stored where it will spoil
- Stocktakes completed in hours with variances traceable to a specific movement
- Dispatch accuracy that shows up as fewer credits and fewer angry Monday phone calls
- Directed picking removes discretion from experienced staff, and that transition needs managing
- Hardware for chilled environments costs more and needs a replacement budget
- A WMS only works if the underlying stock data is accurate, so inventory discipline comes first
- For a facility under about 1,000 pallet positions with simple product, this is likely over engineering
- !They have never specified hardware for a chilled environment. Ask which scanners they recommend and why
- !Picking described as first in first out. Ask why expiry rather than receipt date should drive the sequence
- !No site survey of wifi coverage. Ask them to walk the racking with a signal meter before quoting
- !Go live proposed as a single cutover. Ask for a zone by zone rollout plan instead
If warehouse management is on the roadmap, business intelligence (BI) dashboards, lms, internal tools usually follow within the year. Budget them as one conversation. Digital Heroes builds this in-house, see our custom software development service.

Frequently asked questions
What does a warehouse management system cost for a Nelson coolstore?
Directed picking and putaway for a single facility runs NZ$45,000 to NZ$80,000 over three to five months. A full system with zones, cycle counting and dispatch verification is NZ$80,000 to NZ$160,000. Multi facility builds with freight integration reach NZ$260,000.
Can it enforce first expiry first out picking?
Yes, and it is usually the primary reason to build. The system directs the picker to a specific batch and location based on expiry and the customer's required remaining shelf life, rather than leaving the choice to whoever is on the forklift. Write off reduction from this single rule often justifies a large share of the build.
Will scanners work in dead spots between racking?
They will if the app stores data locally and syncs when it regains signal, which is a design decision rather than a network problem to solve with more access points. A wifi survey should still happen, because there are dead spots worth fixing and dead spots worth designing around. Ask for both the survey and the offline capability.
How does it handle multiple temperature zones?
Each location carries a temperature class and each product carries a requirement, and putaway refuses a location that does not match. Overrides exist but they are recorded with a reason and a user, which gives you an audit trail when a customer or verifier asks. This is difficult to configure convincingly in generic warehouse modules.
Do we need new hardware?
Possibly. Standard scanners struggle with condensation and battery life in chilled environments, and the recommendation should come from someone who has deployed in a coolstore before. Budget for hardware separately from software and include a replacement cycle, because devices in cold conditions do not last as long as vendor specifications suggest.
How long does stocktake take once the system is live?
Continuous cycle counting largely replaces the single annual count, so instead of shutting down for a day you count a section at a time during normal operation. Variances become traceable to specific movements rather than appearing as an unexplained total. Most Nelson facilities see stocktake effort drop substantially in the first year.
Should the WMS or the ERP own stock?
One of them must, and it should be whichever holds batch and expiry detail reliably. Splitting ownership between a WMS and an ERP is a common cause of persistent reconciliation problems. Decide this in discovery and design the integration around a single source of truth.
How do we roll it out without disrupting dispatch?
Zone by zone or product group by product group, running the old process alongside for the first area until the team is confident. Never cut over an entire chilled facility in one weekend during a peak period. For Nelson operations that means avoiding February and the pre Christmas run entirely.
What are the ongoing costs?
Hosting of NZ$200 to NZ$800 a month, 15 to 20 percent of build cost annually for support, and a hardware replacement budget for scanners and printers. Include after hours support in the agreement, because a WMS failure during a dispatch window stops the building.

Who can build custom warehouse management software for a business in Nelson?
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 Nelson 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.
