When Hershey's couldn't fulfil $100 million in Halloween orders because their shiny new ERP system failed during the busiest season, something broke beyond just their supply chain. When Revlon's North Carolina facility ground to a halt, unable to process $64 million in orders, it wasn't just a technical failure. These stories share a common thread: enormous investments in "proven" enterprise software that simply didn't fit the way these businesses actually worked.
Australian businesses watch these disasters from afar and draw a logical conclusion. Custom ERP must be prohibitively expensive if even Fortune 500 companies are forced to use off-the-shelf systems. Better to accept the compromises of a standard platform than risk building something bespoke.
That logic made sense five years ago. It doesn't today!
What "Proven" Really Costs
The conventional wisdom in Australian business circles goes something like this: deploy a market-leading platform from SAP, Oracle, or Microsoft Dynamics. It's what everyone uses. Battle-tested. Lower risk.
Here's what the numbers actually say. Between 55% and 75% of ERP implementations fail to deliver their promised outcomes. Not small businesses gambling on unproven startups. Established organisations implementing platforms used by thousands of other companies.
Mission Produce, after launching their new system in 2021, couldn't answer basic questions. How many avocados do we have? Are they ripe? Have we paid this invoice? J&J Snack Foods lost $20 million in a single quarter from implementation disruptions. HP, on their 35th ERP deployment (not their first, their thirty-fifth), lost $160 million in revenue when system conflicts cascaded through their supply chain.
The pattern repeats because the underlying assumption is flawed. Your business processes should not bend to fit someone else's version of "best practice." When Lidl walked away from a €500 million SAP project after seven years, the problem wasn't SAP's engineering quality. Their retail pricing model and Lidl's purchase-price inventory system were fundamentally incompatible. No amount of configuration could bridge that gap.
For Australian businesses operating under local regulatory frameworks, this mismatch cuts deeper. A Perth radiology clinic isn't asking for bells and whistles when they need Privacy Act compliance tracking. A mining company isn't being difficult when DEMIRS submissions must follow exact state government specifications. A legal practice handling FOI requests can't approximate compliance. The system either handles these requirements correctly, or it exposes the organisation to serious legal and regulatory risk.
These aren't customisations. They're the core of how Australian businesses must operate.
The Update Nightmare
The initial implementation pain is only the beginning. Off-the-shelf systems demand regular updates for security patches, new features, and continued vendor support. Each update introduces fresh uncertainty into your operation.
Consider HP's experience. Thirty-four successful ERP deployments gave them confidence. The thirty-fifth, meant to be routine, spiraled into $160 million in losses. If a technology company with dedicated teams and deep internal expertise struggles to predict how system updates interact with their specific configuration, the risk multiplies for organisations without those resources.
The arithmetic is brutal. Major ERP platforms push updates twice yearly. Over a ten-year lifecycle, that's twenty separate occasions where your mission-critical systems face disruption risk. Each update demands testing and validation. Any customisations you've made need rework to remain compatible. Organisations that heavily customise off-the-shelf systems pay twice: once for the initial customisation, then repeatedly to maintain it through every upgrade cycle.
This dependency creates an uncomfortable reality. Your business continuity sits partially in the hands of product managers in Silicon Valley or Germany who decide feature priorities and depreciation schedules without knowing your Australian compliance requirements exist. When SAP announced limited support extension for their legacy ECC system in 2025, thousands of customers who hadn't migrated to S/4HANA faced a hard deadline regardless of whether the timing suited their business needs.
The AI Revolution in Code Development
Something fundamental shifted in 2023 and 2024 that changes the bespoke versus off-the-shelf calculation entirely. Generative AI tools transformed how software gets built.
When properly implemented with experienced developers guiding the process, AI-assisted development can generate quality code at speeds that seemed impossible two years ago. Studies from organisations implementing AI-driven testing report 60-70% time savings in test generation while achieving more comprehensive coverage. Tasks that traditionally required weeks of developer time can now be completed in hours when the AI is properly directed and the output rigorously validated.
This isn't about replacing developers with AI. That approach fails consistently. The technology handles repetitive, error-prone work like generating test scripts, documenting code, creating boilerplate structures, and identifying obvious bugs during development. The humans do what humans do best: understanding your business logic, designing systems that match your actual workflows, making architectural decisions, and ensuring security and compliance requirements are embedded correctly from the foundation up.
The productivity gains are real, but they come from augmentation, not automation. A skilled development team using AI tools effectively can deliver substantially more in less time. The economic model that made custom development prohibitively expensive has been genuinely disrupted.
For Australian businesses, this shift matters. The cost barrier that pushed most organisations toward off-the-shelf solutions is eroding. Custom development timelines are compressing. In many cases, projects that once required 12-18 months can be completed in 3-6 months when scoped appropriately and built with modern AI-assisted approaches. The rigorous testing and quality assurance that companies traditionally sacrificed to control budgets becomes economically viable.
Security You Control
Off-the-shelf ERP systems present a unique security challenge. When a vulnerability is discovered in SAP or Oracle, attackers worldwide know exactly which systems are vulnerable. The software's ubiquity becomes a liability. Patches must be deployed across thousands of installations simultaneously, creating windows of exposure.
Purpose-built systems operate differently. Your codebase isn't documented in public forums. Attackers can't download trial versions to probe for weaknesses. Security vulnerabilities that exist in your system don't automatically exist in thousands of other installations. You control the update schedule based on your security assessment, not vendor timelines driven by their global customer base.
Australian data residency regulations add another layer. Purpose-built systems deployed on Australian infrastructure ensure your data stays within our borders under Australian legal jurisdiction. When dealing with healthcare records, government documents, or sensitive commercial information, knowing exactly where your data lives and who can access it matters enormously.
The Stability Paradox
Off-the-shelf systems market themselves on stability and reliability. The reality is more nuanced. Those platforms are stable in the aggregate, across thousands of installations. Your specific instance, with your particular customisations, integrations, and data patterns, is unique. The stability guarantee doesn't extend to your configuration.
Purpose-built systems invert this relationship. The platform is yours. Changes happen when you decide they're necessary, not when a vendor's global release schedule dictates. Updates are tested against your actual data and workflows, not generic test cases. You're not affected when another organisation's edge case triggers a platform-wide bug fix that breaks your setup.
This controlled stability matters enormously for businesses where downtime carries real costs. A mining operation that can't process shift rosters and equipment maintenance schedules faces immediate safety implications. A healthcare provider without access to patient scheduling and medical records can't deliver care. These aren't inconveniences. They're operational crises.
What This Means for Perth and Western Australia
Western Australia's economy runs on sectors where ERP systems are critical infrastructure. Mining and resources, government services, healthcare, professional services, legal practices, logistics. Each of these operates under specific regulatory frameworks that weren't written with global software platforms in mind.
The traditional advice has been to find the least-bad fit among major vendors, then spend years working around their limitations. That made sense when custom development meant multi-million dollar budgets and multi-year timelines. Those constraints are dissolving.
Consider what becomes possible. A Perth radiology clinic processing thousands of scans monthly could have a system that integrates directly with imaging equipment, manages practitioner credentials against AHPRA requirements, automates Privacy Act-compliant reporting, and handles billing that reflects both Medicare and private insurance complexity. All while keeping data on Australian servers under Australian legal jurisdiction.
A mining services company could embed DEMIRS compliance into daily workflows rather than bolting it on through brittle integrations. Equipment maintenance could follow manufacturer specifications exactly rather than forcing everything into generic asset management templates. Payroll could handle the actual complexity of FIFO rosters, RDO accrual, and multiple awards without elaborate workarounds.
A legal practice managing FOI requests and complex litigation could work with a system designed around how solicitors actually operate, with compliance and audit trails built into the foundation rather than added as reporting afterthoughts.
These aren't fantasies. They're engineering problems that become economically solvable when development costs compress by 40-60% through AI-assisted approaches.
The Path Forward
This isn't an argument that every business needs custom software. Genuinely standard operations with straightforward requirements can still thrive on well-implemented off-the-shelf platforms. But the barrier that kept most mid-sized Australian businesses locked into that model is vanishing.
If your organisation continually struggles with your ERP system, if you've built elaborate workarounds to handle what should be standard operations, if updates fill you with dread rather than anticipation, the calculation has changed enough to warrant fresh consideration.
Purpose-built systems carry their own responsibilities. You own the maintenance. You manage the hosting infrastructure or choose who does. You're responsible for security updates and system evolution. These aren't drawbacks so much as different trade-offs. Instead of depending on a vendor's global roadmap, you control your own technical direction. Instead of waiting for fixes to problems that affect you but not their broader customer base, you prioritise what matters to your operation.
The approach Tricore Tech takes builds systems from the ground up using modern development practices. AI assists in accelerating the process, but experienced developers remain at the center, making architectural decisions and ensuring the system genuinely solves your problems rather than creating new ones. The result is software that fits your business because it was designed specifically for your business.
This isn't universally cheaper than off-the-shelf. Initial investment can be comparable or higher depending on your requirements. The economic advantage emerges over time. No ongoing license fees tied to user counts. No forced upgrade cycles. No paying repeatedly to maintain customisations through vendor updates. Most significantly, no operational friction from forcing your processes into someone else's template.
The question isn't whether your business can afford custom development. It's whether you can continue affording the hidden costs of misaligned software, the workarounds, the update anxiety, the compromises that seem small individually but compound into genuine operational drag.
The economics have fundamentally changed. The conversation should too.
