Half your Seaview steel stock is remnants on a rack, and no product in the country tracks that properly
Custom inventory management software for a Lower Hutt manufacturer or distributor runs NZ$55,000 to NZ$130,000 over 4 to 7 months. Fishbowl, Cin7 and Unleashed all handle discrete units well, and Cin7 and Unleashed were built in New Zealand so they understand the local context better than most. Where they stop is material that is not a unit: a 6 metre length that becomes a 2.3 metre remnant, a coil measured by weight, a batch with a heat number that must stay attached to whatever is cut from it. That is most of the value sitting on a Seaview rack, and in almost every workshop it is invisible to the system.
Your stock system says you have four lengths of 50x50 SHS. In reality you have one full length, a 2.3 metre offcut behind the saw, a 1.1 metre piece someone put on the rack with no label, and a length that was cut for a job that got cancelled. The buyer orders more because the system says less than reorder point, and the remnant rack grows again. Multiply that across grades and sections and the money tied up is significant.
The second problem is traceability. For structural or pressure work you need the heat number and mill cert to follow the material from the length into the finished part. Off-the-shelf systems treat certificates as attachments on a purchase order, which means when a cut piece goes into a fabrication the chain breaks. Somebody rebuilds it later from a delivery docket and a good memory, which is fine right up until it is not.
Why the usual tools struggle in Lower Hutt
- Remnants and offcuts are invisible to the system, so you reorder material you already own and the rack keeps growing
- Heat numbers and mill certs stop at the purchase order, so traceability into a finished fabrication is reconstructed by hand
- Material issued to a job is recorded after the fact if at all, so job cost is always an estimate
- Consignment and customer-supplied material sits on your floor with no clear ownership record
What a custom inventory management build changes
You build when your stock is not units. A Lower Hutt build tracks material by length, weight or area, records every cut so a remnant becomes a real stock item with its own location and heat number, and keeps traceability unbroken from delivery through cutting into the finished part. It handles consignment and customer-supplied material as distinct ownership types, prices issues at the cost of the specific piece rather than an average, and gives the saw operator a scan-and-cut flow that takes seconds. That is a materially different data model from unit-based inventory, and it is why configuring Cin7 harder does not get you there.
- A significant share of your stock value is remnants, offcuts or material measured by length or weight
- You need heat number traceability into finished parts and currently rebuild it manually
- Material is issued to jobs retrospectively, so job cost is never accurate during the job
- You hold consignment or customer-supplied material and ownership is unclear in your system
- Your stock is discrete units with barcodes and no cutting involved
- Cin7 or Unleashed already gives you accurate counts and your team trusts them
- Traceability is not a customer requirement in your market
- You are under about fifteen people and a well-run spreadsheet still reflects reality
- Remnants become findable stock with a location, which stops you buying material already sitting on the rack
- Unbroken heat number and mill cert traceability from delivery to cut to finished fabrication
- Material issued to jobs at the moment of the cut, so job cost is accurate while the job is still live
- Clear ownership of consignment and customer-supplied material, which removes a recurring source of disputes
- Reorder decisions based on genuinely available material rather than a count that ignores half your yard
- Scan-at-the-saw discipline is a real behaviour change, and without it the data degrades within weeks
- You need hardware that survives a workshop, which adds cost beyond the software itself
- Cin7 and Unleashed ship features you will now build yourself, including some you have not thought about yet
- Stock accuracy exposes uncomfortable truths early, and the first stocktake after go-live is usually a difficult conversation

The engagements Lower Hutt teams bring us most often: Fishbowl alternative, Cin7 alternative, real-time inventory, purchase order management, demand forecasting, inventory management software and stock control system.
Inventory Management pricing in Lower Hutt: the real numbers
| Project scope | Typical cost | Timeline |
|---|---|---|
| Material tracking with remnants and location management | NZ$55k to NZ$80k | 4 to 5 months |
| Adds heat number traceability and job issue at the cut | NZ$85k to NZ$110k | 5 to 6 months |
| Multi-site build with consignment and supplier integration | NZ$110k to NZ$130k | 6 to 7 months |
From kickoff to launch: the schedule
Exactly what you get
Stock records that match what is physically on the rack. Concretely: material tracked by length, weight or area; remnants created automatically at every cut with their own location and heat number; unbroken traceability from goods receipt into the finished fabrication; a scan-and-cut flow that takes seconds with gloves on; consignment and customer-supplied material clearly owned; and reorder logic that counts usable remnants and committed material. You get the code, the hardware specification and a documented stocktake process for go-live. Material issues feed job cost in your ERP (Enterprise Resource Planning) software, purchasing connects to supply chain management (SCM) software, physical movement is handled by a warehouse management system (WMS), and cost of goods lands in accounting software.
How to choose a developer in Lower Hutt
Take candidates to the remnant rack. The right supplier will start asking how pieces get labelled, who decides a remnant is worth keeping, and what happens when a piece is cut for a job that gets cancelled. The wrong one will describe a barcode system. Ask them to sketch the data model for a length of steel that has been cut three times and still needs its original heat number, because if they cannot draw it in five minutes they have not built this before. Confirm the hardware plan including scanners, mounting and who supports them, and insist that go-live includes a supervised stocktake, because a new system loaded with the old system's wrong numbers helps nobody.
- !They model everything as units. Ask how a 6 metre length becomes a 2.3 metre remnant in their design
- !Traceability is described as file attachments. Ask how a heat number follows a cut piece into a fabrication
- !No hardware discussion. Ask what scanner they recommend for a dusty workshop and who supports it
- !They skip the stocktake plan. Ask how opening balances get established and how long that takes
- !Reorder logic ignores committed material. Ask whether their calculation accounts for open jobs and usable remnants

Frequently asked questions
What does custom inventory software cost for a Lower Hutt steel or engineering business?
NZ$55,000 to NZ$80,000 for material tracking with remnants and location management, delivered in 4 to 5 months. Adding heat number traceability and issue-at-the-cut takes it to NZ$85,000 to NZ$110,000. The remnant model is the biggest driver, because tracking material by length rather than by unit changes almost every screen.
Can Cin7 or Unleashed handle offcuts if we set them up carefully?
Not really, and the workarounds are worse than the problem. You can create a separate product code for each remnant length, which produces a product catalogue that grows without limit and that nobody maintains. Both products are strong on discrete units and New Zealand context, which is why the sensible pattern is often keeping them for finished goods while building the material side.
How does heat number traceability actually work in a custom system?
The heat number attaches to the material at goods receipt, and every cut creates child records that inherit it. When a cut piece is issued to a fabrication, the finished part carries the full chain back to the mill cert. Producing traceability for a client then takes a minute rather than a walk through the yard with a torch.
What hardware do we need on the shop floor?
Rugged handheld scanners or mounted tablets rated for dust and knocks, plus label printers that survive a workshop environment. Budget NZ$800 to NZ$2,500 per station depending on ruggedness, and confirm who provides support before you buy. The interface matters as much as the device, because a screen that needs precise taps fails with gloves on.
How do we get accurate opening stock at go-live?
A full supervised stocktake, ideally over a shutdown weekend, with remnants labelled and located as part of it. This is the least popular and most important part of the project, and skipping it means launching with wrong numbers that destroy trust in the system within a month. Plan for it in the project schedule rather than treating it as an operational afterthought.
Can the system tell us what we should stop stocking?
Yes, once you have six to twelve months of real issue data. Slow-moving analysis by grade and section, combined with remnant accumulation patterns, usually identifies material you keep out of habit rather than demand. This is often where the build starts paying for itself in freed working capital.
How does GST work on consignment and customer-supplied material?
Consignment stock you have not yet purchased is not your inventory for accounting purposes, and the GST tax point arises when ownership transfers rather than when it arrives on your floor. Customer-supplied material is never yours at all and should never appear in your stock valuation. Your system needs to distinguish these clearly, and your accountant should confirm the treatment before go-live.
Will this integrate with our existing ERP or accounting system?
Yes, and the usual pattern is that the inventory system owns material and pushes issues and valuations into your ERP or Xero. Deciding which system is the master for each data type is the most important design decision, and ambiguity there causes most integration failures. Settle it in discovery, in writing.
How long before shop-floor scanning becomes habit?
Typically 4 to 8 weeks with visible supervisor support and a flow that genuinely takes seconds. Adoption fails when scanning is slower than not scanning, or when there is no consequence for skipping it. Digital Heroes recommends running a daily accuracy check for the first month so problems surface while they are still small.

Who can build custom inventory management software for a business in Lower Hutt?
Digital Heroes builds custom inventory 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 Lower Hutt 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 inventory 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.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it. The YouTube channel is at https://youtube.com/@DigitalMarketingHeroes, the Fiverr profile at https://www.fiverr.com/shreyanshsin261, and the Upwork profile at https://www.upwork.com/freelancers/shreyanshsingh. Client reviews sit on Clutch at https://clutch.co/profile/digital-heroes-0 and Trustpilot at https://www.trustpilot.com/review/digitalheroes.co.in, and the company page is at https://www.linkedin.com/company/digital-heroes-1/.
Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
