Risks Of ERPs

Business risks associated with ERP systems

Projects succeed when the challenges of ERP are identified early and managed with discipline. Below are the most common risk areas organisations face during ERP selection, implementation and operation.

• Scope creep and requirements gaps

Scope creep is one of the most common challenges in ERP projects.

It occurs when additional requirements are introduced after the project has begun, often without formal approval or a clear understanding of the impact on time, cost and resources. This can happen when early requirements are too high-level, when stakeholders have different interpretations of what the system should deliver or when operational details are overlooked during planning.

As the project progresses, gaps in requirements may surface, leading to rework or late design changes. These changes can disrupt implementation schedules, stretch project teams and dilute focus on the original business objectives. Without strong governance and requirement validation, scope creep can quickly become a major source of risk.

• Data migration complexity

ERP systems depend on accurate, complete and well-structured data to support reporting and daily operations.

Data migration becomes complex when information is sourced from multiple legacy systems with varying formats, definitions and quality standards. In many cases, data issues are not fully visible until migration activities begin.

If data cleansing, validation and reconciliation are rushed or underestimated, organisations risk introducing errors into the new system. This can affect financial reporting, inventory accuracy and operational processes.

Poorly managed migration can also disrupt business continuity during cutover, particularly when users lose trust in the ERP data.

• Change management and adoption

ERP implementations introduce new processes, workflows and ways of working across the organisation. Without structured change management, employees may struggle to understand how their roles are affected or why changes are being made. This can result in resistance, low engagement and reduced system usage.

When adoption is limited, users may rely on spreadsheets or legacy tools instead of the ERP. This undermines data integrity and reduces the system’s overall value.

Ongoing support demands may increase as teams seek help outside standard processes, placing pressure on internal support functions after go-live.

• Customisation and technical debt

Customisation is often used to address specific business needs, but it carries inherent risk. When changes move too far away from standard ERP functionality, the system becomes more complex to maintain and harder to upgrade. Over time, these decisions accumulate into technical debt.

This technical debt can limit future flexibility and increase reliance on specialist resources who understand the custom logic. It may also delay upgrades and restrict access to new features released by the ERP vendor. As the system evolves, maintenance effort and support costs typically rise.

• Vendor and partner selection risk

The success of an ERP project is closely linked to the experience and delivery approach of the chosen vendor and implementation partner.

A poor fit can lead to misaligned expectations, inconsistent delivery methods and limited accountability during critical stages of the project.

Risks increase when partners lack relevant industry experience, local support capability or a clear understanding of the organisation’s operating model. In these situations, knowledge transfer may be limited, and the business may struggle to maintain the system effectively after implementation.

• Budget, total cost of ownership and hidden costs

ERP projects involve more than upfront software and implementation fees. The total cost of ownership is shaped by factors such as:

• Internal resourcing and backfill requirements
• Change management activities
• Data preparation and cleansing
• System integration with existing platforms
• Post go-live optimisation and support

When these elements are not fully accounted for during planning, budgets can be exceeded quickly.

Cost overruns often arise from:

• • Delivery delays
  • Rework caused by late changes
  • Additional support requirements that were not anticipated

• Cloud vs on-prem risk trade-offs

The choice between cloud and on-prem ERP deployment introduces different operational, technical and compliance considerations.

Cloud-based solutions may reduce infrastructure management and offer scalability, but they can raise concerns around data residency, integration complexity and ongoing subscription costs.

On-prem deployments can provide greater control in certain environments but may require higher upfront investment and ongoing infrastructure management.

Risks emerge when the selected deployment model does not align with regulatory obligations, integration requirements or operational expectations. For a deeper comparison, you can review our overview of ERP deployment models.

Risk mitigation checklist

Managing the disadvantages of ERP requires structure, visibility and clear ownership across the project lifecycle. While no ERP program is risk-free, a disciplined approach can significantly reduce disruption and support more predictable outcomes.

1. Clear business objectives and documented requirements

ERP initiatives deliver better outcomes when they are anchored to clear business objectives rather than a list of system features.

Objectives help define what success looks like and guide prioritisation when trade-offs arise during delivery. Documented requirements translate those objectives into practical expectations across finance, operations and other functions.

Well-defined requirements reduce ambiguity and create a shared understanding among stakeholders. They also provide a stable reference point for assessing change requests, helping teams evaluate impact before making decisions.

Without this foundation, ERP projects are more likely to drift away from original goals.

2. Defined governance and decision-making authority

Governance structures establish who is responsible for decisions and how issues are resolved. Clear decision-making authority ensures that project teams are not stalled by uncertainty or conflicting direction. Governance also provides a framework for managing risk, scope changes and priorities as the project evolves.

Defined roles and escalation paths allow issues to be addressed quickly and consistently. This helps maintain momentum during delivery and reduces the likelihood that unresolved decisions will impact timelines or quality.

3. Early data assessment and migration planning

Data readiness plays a critical role in ERP success.

Early assessment helps identify data quality issues, inconsistencies between systems and gaps in ownership before migration activities begin. This visibility allows organisations to plan remediation activities without placing pressure on delivery schedules.

Migration planning should include validation, reconciliation and testing processes to support data accuracy. When data issues are addressed early, cutover activities are more controlled, and users are more likely to trust the system after go-live.

4. Structured change management and training programs

ERP systems introduce new ways of working that affect daily tasks across the organisation. Structured change management helps users understand what is changing and why. This reduces uncertainty and supports a smoother transition to new processes.

Training programs should be aligned to user roles and delivered close to system usage. Ongoing communication and support after go-live help reinforce correct behaviours and reduce reliance on informal workarounds.

5. Controlled customisation and design standards

Customisation decisions should be governed by clear design standards and approval processes. This ensures that changes are introduced only when there is a strong business case and a clear understanding of the impact on future maintenance and upgrades.

By limiting unnecessary customisation and favouring standard functionality, organisations can reduce system complexity and maintain flexibility over time. This approach supports a more manageable support effort and simplifies future system changes.

6. Careful vendor and partner evaluation

ERP delivery outcomes depend heavily on the experience and capability of vendors and implementation partners. Careful evaluation helps ensure alignment in delivery approach, communication style and industry understanding.

Due diligence should consider the partner’s track record, local support capability and ability to provide ongoing assistance after implementation. Strong alignment reduces delivery risk and supports more effective knowledge transfer.

7. Transparent cost tracking and reporting

ERP costs span planning, implementation, and ongoing operations. Transparent tracking provides early insight into cost pressures and helps teams respond before issues escalate. Regular reporting supports informed decision-making and reduces the risk of unplanned expenditure.

Leverage Technologies supports clear cost visibility throughout the ERP lifecycle, helping organisations understand how decisions affect overall spend. Clear visibility into costs also helps organisations manage the total cost of ownership over time, rather than focusing solely on initial project budgets.

8. Deployment model assessment aligned to business needs

Selecting a deployment model requires careful consideration of regulatory requirements, operational constraints and integration needs. Cloud and on-prem options introduce different risk profiles that should be assessed against the organisation’s operating model.

Leverage Technologies helps organisations evaluate deployment models in the context of business requirements, compliance obligations and existing systems.

A well-aligned deployment model supports performance, compliance and future change. Taking the time to assess these factors helps reduce risk and supports a more stable ERP environment as business needs evolve.
