ERP Team Structure: Roles and Responsibilities To Manage Change (2026) – Shopify

Enterprise resource planning (ERP) teams bring technical, operational, and business stakeholders into one decision-making group. ERP affects several business areas, including inventory, operations, finance, fulfillment, and customer-facing workflows. 

Panorama Consulting Group’s “2026 ERP Report” found that ERP projects increasingly function as business-transformation initiatives, with delays often tied not to technical execution but to approvals, sign-offs, and cross-functional alignment. That makes team structure a governance decision, not just a staffing exercise.

Without a clearly defined ERP team, system design may not align with business requirements. This article will explore why ERP team structure matters, which roles and responsibilities to include, and how to organize ownership before implementation begins.

What is an ERP team?

The ERP team is a cross-functional group that plans, implements, and manages the enterprise resource planning (ERP) system within a company. This is the team responsible for making decisions about ERP and coordinating how finance, operations, and ecommerce workflows connect. 

The team is responsible for system functionality and supporting adoption across departments. ERP teams help enforce system processes and resolve cross-department conflicts. They keep operational decisions aligned where inventory, order, fulfillment, and financial data overlap.

These teams split into two groups:

• The core team includes decision-makers: executive sponsors, project managers, and subject matter experts from finance, operations, and other fields.
• The extended team includes implementation partners, developers, quality assurance (QA), security, finance ops, ecommerce leads, and more. ERP implementations involve software, processes, data, and organizational change.

The ERP team includes members who understand the flows between ERP and commerce systems. Orders, inventory, fulfillment, B2B pricing, returns, and store operations—the ERP system tends to touch all of them. Commerce systems and ERP systems are often integrated to support inventory and order accuracy.

ERP systems often introduce additional complexity across workflows. Some organizations use unified commerce platforms to manage orders, inventory, and fulfillment across ecommerce, retail, and B2B channels. That complexity makes commerce a key part of ERP planning, not a late-stage integration detail.

Why the right ERP team matters

ERP implementation success is influenced by how well teams align business goals with system processes. According to PMI, project professionals with strong business acumen reported better schedule and budget adherence and lower project failure rates. For ERP projects, business context helps stakeholders make faster decisions and keep implementation aligned with operational goals.

Common risk factors in ERP implementations include:

• Diffused ownership: According to Panorama’s 2026 ERP report, almost a quarter of organizations reported schedule overruns, and delays often came from approvals, sign-offs, and cross-functional alignment rather than technical execution alone. When no one owns the decision, the project slows down.
• Undefined scope: Panorama’s report also found that more than a quarter of organizations went over their implementation budgets, and the most common reason was an unexpected need for additional technology. Clear ownership by an ERP team helps separate true requirements from late-stage additions.
• Disconnected operations: An ERP system touches everything from finance to inventory to ecommerce. If those teams aren’t represented early, gaps can surface later as order issues, inventory mismatches, testing delays, or training problems.

Consider SANJO, a footwear and apparel brand that was struggling with fragmented systems and weak integration between their online and offline operations.

After migrating to Shopify with ERP integration, the company reported improved payments and personalization. This led to a 50% reduction in logistics time while also reducing errors in inventory management between their online store and physical locations. 

SANJO’s example shows why commerce workflows belong in ERP planning: When ecommerce and operations stay aligned, the team can turn system alignment into measurable gains.

Core ERP team roles and responsibilities

ERP implementations begin with defined roles and responsibilities. But the goal isn’t just to fill seats. Each role needs clear ownership, decision-making authority, and a connection to the business processes the ERP system will support. 

Executive sponsor

The executive sponsor is typically a C-suite executive: CIO, COO, CFO, or CEO. 

• What they own: The overall direction of the ERP project. Other team members may own the project, but the executive sponsor keeps the implementation tied to business priorities and goals.
• Their role: Oversight, but not day-to-day work. The executive sponsor is responsible for removing organizational obstacles that slow progress.
• Mistakes to avoid: Disengaged sponsors who delegate too much. Even without day-to-day responsibilities, an ERP project needs visible leadership because it affects priorities across finance, operations, IT, and commerce.

Project owner, or ERP lead

The project owner, also known as ERP lead, is a senior leader. They need enough authority to guide the project from the business perspective. This role involves more regular oversight than the executive sponsor role.

• What they own: Scope and business alignment decisions. They’re one of the core team members making sure the ERP system supports cross-department business needs.
• Their role: Bridge the gaps, especially between strategy and execution. This role requires strong communication skills to translate business goals into requirements. They must balance priorities across teams.
• Mistakes to avoid: Lack of authority or unclear ownership. This role needs decision-making power to prevent implementation delays and conflicting priorities between teams.

Project manager

The ERP project manager is the day-to-day manager in charge of ERP implementation. They’re often tasked with keeping the project on schedule. This is more of a hands-on role than the two previously described positions.

• What they own: Timeline, task coordination, and budget tracking. They’ll also be responsible for managing schedules and assigning specific responsibilities to the team.
• Their role: Coordinate across internal teams (IT, commerce, finance) along with external partners and stakeholders. They also coordinate dependencies between operational, technical, and commerce workstreams so scheduled milestones stay aligned.
• Mistakes to avoid: Losing sight of business impact in the pursuit of perfectly managed timelines.

Subject matter experts (SMEs)

Subject matter experts (SMEs) can be technical experts and other business professionals who know how the business is run, especially given specific functions. Finance, inventory, order fulfillment, and customer service teams often have employees who understand the particular quirks of each system.

• What they own: Requirements, workflow validation, and testing, such as user-acceptance testing. They’ll define how processes should work in the context of real operations across key business workflows.
• Their role: Take day-to-day business processes and help migrate them into ERP workflows, then test those workflows. They may also have to train other teams after implementation.
• Mistakes to avoid: Being occasional advisors rather than core contributors. SMEs have to have a voice to speak up. Without SME input, teams may discover workflow gaps or adoption problems too late in the implementation process.

IT and integration lead

The IT and integration lead builds the technical foundation of the ERP system and its cross-platform connections.

• What they own: System architecture, security, data flows, and integrations. They typically need access to different ecommerce, point-of-sale (POS), customer relationship management (CRM) systems, and warehouse management systems (WMS).
• Their role: They ensure data flows reliably across systems so inventory, orders, and fulfillment workflows stay aligned across platforms. They make sure data moves reliably during implementation and after launch.
• Mistakes to avoid: Focusing only on technical performance without aligning to business workflows. Clean integrations are important, but they have to support meaningful business processes.

Data migration lead

The data migration lead keeps information flowing into the new system. They are responsible for maintaining data accuracy and consistency, which supports system scalability.

• What they own: Data auditing, mapping, and deduplication. They often define how to structure key data from every system, including customer, pricing, and order data.
• Their role: They provide clean and reliable data across ERP, ecommerce, and retail systems. Data migration is also critical to maintain continuity from older systems.
• Mistakes to avoid: Putting data on the back burner. Poor data quality at launch can create reporting issues.

Change-management and training lead

The change-management and training lead ensures that different teams in the business adopt the new ERP system.

• What they own: Internal communication, training plans, and the effectiveness of that training. They can also offer post-launch support.
• Their role: Prep every team for the ERP changes, then train users on the new workflows. They then reinforce adoption after the system goes live.
• Mistakes to avoid: Underinvestment. Poor training and communication can slow adoption and create operational errors after launch.

Change management is often under-prioritized. Panorama’s 2025 report found only one-third of organizations even included organizational change management as an intense focus.

Implementation partner and external consultants

Implementation partners and consultants fill in gaps by offering up their specialized experience, as well as some additional capacity, if needed.

• What they own: Whatever’s missing, such as system configuration or technical expertise. They can also educate an ERP team on industry best practices.
• Their role: Fill in skill gaps and guide complex decisions based on previous ERP consulting experience. They can also support integrations, testing, training, or workflow design during implementation.
• Mistakes to avoid: Don’t over-rely on external partners, especially if compensating for poorly-defined internal ownership roles. External support can accelerate execution, but internal teams still need to own decision-making, workflows, and long-term system governance.

How to structure an ERP team

Defining roles is only one step. But the ERP team has to follow a clear decision-making structure to keep the implementation moving.

Organizations may structure ERP teams in phases rather than building a full structure at once. A common structure includes:

• The steering committee includes the executives, like the project owner and executive sponsor, who handle oversight and make decisions about how problems should be resolved.
• The core team is the day-to-day ERP team, which can include the above, but also includes roles like project manager, SME, IT/integrations experts, and more. They’re responsible for the day-to-day execution of the plan.
• Other functional workstreams may be brought in as needed, especially when specific functions (finance, ops, data) are involved. These workstreams can handle decisions and testing related to their area of the business.

Clear decision-making authority is critical. Establish whose decisions carry weight, and who owns which parts of the process. Unclear decision-making authority can delay project progress as people carry out individual steps without clear ownership or approval authority.

Structuring the ERP team is also about context. Leadership should decide how often to hold regular meetings, then highlight potential escalation paths if there are problems. For example, a commerce team may need a clear escalation path when implementation decisions affect order workflows.

Smart structuring led Simon Pearce to a successful overhaul. Dealing with disconnected ecommerce, POS, and B2B systems—including inventory that only updated once per day—the company consolidated to a unified platform. For Simon Pearce, that also meant consolidation between teams like retail and ecommerce. This alignment helped improve visibility across systems and teams.
