Custom-built versus implementing an existing platform
Most ERP needs are well served by implementing an existing platform (see our ERP Implementation services) — it's faster and cheaper. Custom ERP development is for the businesses whose process is different enough that configuring an existing platform means fighting it constantly, or whose scale and complexity justify software built specifically around their operations. This is a bigger investment, and we'll only recommend it when implementation of an existing platform genuinely can't get you there.
We typically start any ERP conversation by assessing whether implementation is sufficient before proposing a custom build — the honest recommendation is usually the platform route.
What's included
Our process
Assessment
Honest evaluation of whether custom development is genuinely needed over implementation.
Process mapping
Deep mapping of operations across every department involved.
Architecture
System designed around your actual workflow, not a generic template.
Development
Built in phases, with each module usable before the next begins.
Rollout
Migration, training and phased go-live across departments.
Who this is for
Larger or highly specialised businesses whose operations don't fit existing ERP platforms without extensive customisation that ends up costing as much as a custom build anyway. This is a significant investment — we'll only recommend it after confirming implementation of an existing platform genuinely isn't sufficient.
Engagement & pricing
Priced as a large project, typically phased across departments, with each phase quoted separately as scope firms up. This is a bigger commitment than platform implementation and priced accordingly.
One more thing worth knowing
Custom ERP builds also make sense for businesses planning to license or resell the system internally across group companies — a use case a standard platform's licensing terms often don't accommodate cleanly.
Frequently asked questions
Only when your process genuinely doesn't fit existing platforms even after reasonable configuration — we'll assess this honestly first, since implementation is faster and cheaper when it's sufficient.
Significantly longer than platform implementation — often 4-9 months depending on scope, typically delivered in phases so departments go live progressively rather than all at once.
Yes — phased rollout by department is the more common approach, letting you validate the system before committing to the full scope.
Migrated and reconciled department by department as each phase goes live, with your old systems kept accessible during the transition period.
Yes — ongoing support and maintenance is available on a retained basis, which matters more for custom-built systems since there's no vendor community to fall back on.
