Fishbowl tracks a quantity, but your switchgear is tracked by serial

Custom inventory software for a Newcastle manufacturer runs $45,000 to $130,000 and ships in 3 to 6 months.

The short answer

Custom inventory software for a Newcastle manufacturer runs $45,000 to $130,000 and ships in 3 to 6 months. You build instead of Fishbowl, Cin7, or spreadsheets when your stock is serialised and project-allocated: switchgear, transformers, and spares for Hunter mines and wind farms, each traced by serial and reserved against a job. Quantity-based tools cannot tell you which unit is where or which job owns it.

You make and service heavy electrical gear at Mayfield or Steel River, and your inventory is not really a pile of identical widgets, it is hundreds of serialised units, each with a history, a warranty, and a job it belongs to. Fishbowl and Cin7 think in quantities, so they can tell you that you have twelve of something, but not which specific transformer is allocated to which Hunter project, or which spare has already been promised to a mine shutdown.

So the real picture lives in a spreadsheet beside the system: a serial register, an allocation list, and a warranty log that a coordinator keeps in their head. When a project pulls a unit that was quietly reserved for a wind-farm spare, you find out at the worst possible moment, on site, with a crew waiting.

The problems nobody warns you about

  • Fishbowl and Cin7 track quantities, not the serialised units your business actually manages
  • Project allocation of specific units lives in a spreadsheet the system never sees
  • Warranty and service history per serial is kept off-system, so nobody trusts it
  • A unit reserved for a mine or wind-farm spare gets pulled to another job with no warning

The case for owning your inventory management

Custom inventory software tracks what a Hunter manufacturer really holds: serialised units with history, warranty, and allocation, not just quantities. It reserves a specific transformer against a specific project, keeps the service record with the serial, and stops one job pulling stock promised to another. The serial register and allocation spreadsheet disappear because the system finally models reality.

Digital Heroes builds the full inventory management stack for Newcastle teams. Typical engagements cover stock control system, barcode scanning, multi-location inventory, inventory tracking and Fishbowl alternative.

Exactly what you get

You get inventory software that tracks serialised switchgear and spares the way a Hunter manufacturer actually holds them: by unit, with history, warranty, and job allocation. It reserves specific units for a project, shares stock data with a warehouse system, and reconciles valuation into your accounting build. You own the code and the data.

How to choose a developer in Newcastle

Choose a team that has built serial-level inventory, not just quantity stock, and ask to see per-unit history and job allocation in something they shipped. Confirm they can integrate scanning across your Mayfield and Steel River movements and reconcile stock valuation into accounting for correct GST. A developer who understands electrical and heavy manufacturing for Hunter mines and renewables will treat serialised allocation as the core problem, because it is.

Red flags when hiring (and what to ask instead)
  • !They demo quantity stock and call it serialised. Ask to see per-unit history in a build they shipped
  • !They ignore project allocation. Ask how a specific unit gets reserved for a job
  • !They skip warranty tracking. Ask how service history stays with a serial
  • !They cannot integrate accounting. Ask how stock valuation and GST reconcile
  • !They keep the system on their platform. Ask who owns the data and code

FAQ

Frequently asked questions

What does custom inventory software cost for a Newcastle manufacturer?

Most builds run $45,000 to $130,000. Serial tracking with project allocation starts near $45,000, while scanning, warranty history, and accounting integration run higher. Expect 3 to 6 months depending on integrations.

Why isn't Fishbowl enough for our switchgear?

Fishbowl tracks quantities, but your units are individually serialised with their own history, warranty, and job allocation. It cannot tell you which specific transformer is reserved for which Hunter project, so that truth ends up in a spreadsheet. A custom system tracks every unit by serial.

How does it stop a spare being double-allocated?

By reserving a specific unit against a specific job and alerting anyone about to pull it for another. That prevents the on-site surprise where a wind-farm spare turns out to have been promised elsewhere. Quantity-based tools cannot do this because they do not track individual units.

Can it keep warranty and service history per unit?

Yes. Each serialised unit carries its full history, warranty, and service record for its whole life, which matters for gear serviced across mine shutdowns and renewables maintenance. That history stays on system instead of in a coordinator's memory.

Does it handle barcode or QR scanning across our sites?

Yes. We build scanning for movements across your Mayfield and Steel River operations so stock updates as it moves, rather than being re-keyed later. Scanning is what keeps serialised tracking accurate without adding a data-entry burden.

Will stock reconcile with our accounting for GST and valuation?

Yes. We integrate inventory with your accounting so stock valuation and GST are accurate, which matters for a manufacturer holding significant serialised assets. This removes the manual valuation reconciliation that spreadsheets force.

Can it link to our project system for allocation?

Yes. Units can be allocated directly from a project or job so the reservation is visible to everyone, not buried in a list. That link between inventory and project work is exactly where off-the-shelf tools leave a gap.

How long until it is running our stock?

Plan on 3 to 6 months. We start with serial tracking and allocation, then add scanning, warranty, and integrations. We migrate and reconcile your existing stock and serial data before cutover so you trust the opening balances.

Do we own the inventory data and code?

You do. You receive the source code and the database, so your serial register, allocations, and history are yours to keep. Confirm this before starting, especially with platform-based inventory tools that keep you on their runtime.

What tech stack should a custom inventory system be built on?

A deliberately boring one: PostgreSQL for the stock ledger, a mainstream backend such as Node.js, Python, or .NET, a web dashboard, and a mobile app or mobile web interface for scanning. The data model matters far more than the language; an append-only movement log with atomic stock updates prevents overselling in any stack. Reject anything exotic that only the original developer can maintain.

What are the biggest mistakes first-time software buyers make?

Choosing the lowest bid, paying more than 30-40% upfront instead of on milestones, skipping a written specification, and having no maintenance plan for after launch. The most expensive of the four in Digital Heroes rescue projects is the missing spec: without written acceptance criteria, done becomes an argument instead of a checklist, and every disagreement resolves in the vendor's favor. Fix those four and you have avoided most of the ways these projects fail.

How many people should be working on my software project?

Three to five for a typical focused build: a project lead, one or two engineers, a designer, and part-time QA, which is the standard shape across 2,000+ Digital Heroes projects. Larger platforms justify 6 to 10, but a ten-person team on a small first version usually signals bill padding rather than horsepower. What predicts success is whether a senior engineer is writing your code daily, not the headcount on the proposal.

How many SaaS seats do we need before building custom becomes cheaper?

The crossover usually shows up between 20 and 50 seats on premium tiers. Salesforce Enterprise lists at $165 per user per month, so 40 users cost about $79,000 a year in subscriptions, which is real money against a custom system you would own outright. Run the comparison over three years: if subscription spend beats the build cost plus 15-20% annual maintenance, custom wins on price before you even count workflow fit.

How does custom software stop us overselling across multiple sales channels?

By keeping one authoritative count per SKU and recording every change as an atomic movement, so two orders can never both claim the last unit. Channel integrations sync through a queue with idempotency checks, meaning a webhook that fires twice does not subtract stock twice. Ask any vendor to demonstrate concurrent orders against a single unit of stock; naive builds and generic connectors both fail that test.

Should we start with an MVP or build the full inventory system in one go?

Start with a minimum viable product covering the single most painful workflow, usually receiving, movements, and scanning for one location, then extend in phases. In Digital Heroes delivery experience, phased builds put a working system on the warehouse floor in 8 to 12 weeks and let real feedback shape phase two, while big-bang builds routinely ship features nobody uses. Phasing also spreads the budget across quarters instead of demanding it all up front.

Is building custom cheaper than paying for Cin7 over time?

Usually yes once you pass the three-year mark. Cin7 Omni plans start around $999 per month on its published pricing, roughly $36,000 over three years before add-ons, which overlaps the cost of a full custom build you then own outright with no per-user fees. If you are on a lower Cin7 tier and your subscription runs below roughly $500 per month, staying put normally makes more financial sense than building.
