How does an ERP project work—and what determines the success of the implementation?

The implementation of an ERP system is one of the most significant changes a company can undergo. This is because it’s not just about new software; it’s also about reevaluating processes, managing data, and how employees collaborate on a daily basis. Without clear goals, responsibilities, and priorities, the ERP project can quickly turn into a seemingly endless endeavor with ever-changing requirements and postponed deadlines.
But what really matters? Which project phases are critical? Who should be part of the ERP project team? And how can you ensure a successful ERP go-live without any unpleasant surprises?

In this article, we'll walk you through the six typical phases of an ERP project, key success factors, and best practices for a successful ERP implementation.

Good to Know: Quick Facts About an ERP Project

Project Launch: The Discovery phase is part of the sales process and provides an initial reliable effort estimate.
Project Phases: Discovery, Process Design, User Testing, Go-Live, and Hypercare form the backbone of the ERP implementation.
Data Migration: The ERP migration begins at the start of the project and runs as a separate work stream until shortly before go-live.
Project Duration: An ERP implementation usually takes several months—depending on the scope, data quality, and internal capacity.
Project Team: Management, project leaders, business units, key users, end users, internal IT, and ERP partners all work together to ensure the project's success.

Why are a clear ERP implementation process model and good project management important?

ERP projects are complex because many processes, systems, and stakeholders are interlinked. A clear process model helps manage these interdependencies in a structured way. W Here's what matters when choosing a system, as our guide explains “Finding the Right ERP for Your IT Company”.

A clear ERP implementation process model and professional support ensure the necessary manageability. Project management. This makes it possible to achieve the following goals:

Requirements, costs, and deadlines remain manageable. A structured ERP implementation prevents the project scope, budget, and schedule from spiraling out of control.
Processes, technology, and change management are all interconnected. A proven process model consolidates all relevant tasks into a single ERP project plan.
Cross-departmental processes are effectively integrated. An ERP system for IT companies integrates business processes ranging from quoting to project planning and time tracking, all the way to project-based or recurring billing. If any link in this chain breaks down, it quickly affects cash flow, transparency, and customer satisfaction.

Various systems are seamlessly integrated. Not every task needs to be handled within the ERP system itself. In an integrated Best-of-Breed cloud solution, ERP, CRM (using Microsoft Dynamics 365 Sales ), and ITSM (using Jira Service Management ) work together. This way, each system remains strong in its area of expertise, and relevant data is transferred seamlessly.
Costly customization and special programming are avoided. Uncontrolled customization can quickly become a cost trap during future updates. Based on our project experience, with Microsoft Dynamics 365 Business Central as the foundation and DYCE as the industry extension, we are able to meet approximately 90 percent of the typical requirements of IT companies using the standard solution. Customizations are limited to cases where they create a genuine competitive advantage. This reduces costs and ensures the solution remains updateable.
Typical errors and project risks are avoided. Common causes include unclear or ever-increasing requirements, as well as a lack of decision-making. Shadow processes in Excel, duplicate data entry, and low user acceptance can also hinder the project. In the worst-case scenario, this can result in incorrect or delayed billing.

Who should be on an ERP project team?

An ERP system impacts key business processes—from Sales and projects to service, license management, and billing. Implementing an ERP system is therefore not purely an IT task . It requires decision-making authority, process knowledge, technical experience, and an understanding of the users’ practical perspective. An interdisciplinary project team clarifies requirements, resources, and data quality early on and supports the change process through clear communication. This helps prevent budget overruns, delays, shadow processes, and acceptance issues.

Executive Board and Management: At this level, goals, budgets, and priorities are set. In addition, management actively promotes the change throughout the company.
Internal Project Management: Their responsibilities include coordinating schedules, resources, decisions, and all individuals involved.
Business Units and Key Users: Drawing on their process expertise, they evaluate the proposed solution while also supporting communication and change management.
End Users: As part of testing, they verify whether the new processes and features are practical for everyday use.
Internal IT: They are responsible for access permissions, integrations, data migration, and technical operations.
ERP Partner: Their role encompasses methodology, industry expertise, technical implementation, and support through the go-live phase.

What role does senior management play in an ERP project?

Senior management creates the conditions necessary to ensure that the ERP project remains a priority and can continue to move forward even in the face of conflicting goals or a heavy workload in day-to-day operations. When senior management actively participates in the project, This shows the workforce that the ERP implementation is crucial for the company's future.

The role of management encompasses five key responsibilities:

Ensuring Priority: Management ensures that the ERP project does not consistently take a back seat to day-to-day operations.
Facilitating Decisions: When questions remain unanswered or goals conflict, she ensures that decisions are made quickly and definitively.
Allocate resources: Internal capacity is planned so that project tasks can be completed reliably.
Visibly Supporting Change: Through its active presence, management fosters acceptance and commitment throughout the entire company.
Avoiding Project Delays: In our experience, ERP projects fail less often due to technical issues than due to a lack of decision-making and poor prioritization.

Why Key Users Are Crucial to Project Success

Key users and end users bring different but equally important perspectives to the ERP project: While key users help shape future processes, end users assess their clarity and practicality.

Key users and end users are responsible for the following tasks:

They translate the department's needs into specific processes and system requirements.
New processes and features are being tested so that feedback can be incorporated into the project at an early stage.
Within the department, they support communication, training, and implementation.
Under real-world working conditions, they evaluate the practicality of the new processes.
Employees who are not participating in the workshops are also involved in user testing and provide a fresh perspective.

Why Choosing the Right ERP Partner Is Crucial for Implementation

Methodology and industry expertise provide structure for the implementation. An ERP partner supports the company throughout the process, from the design phase through the hypercare phase. At Singhammer, we combine technical expertise with practical experience in the IT industry.

An Overview of the 6 Phases of an ERP Project

A proven ERP project plan provides clarity regarding tasks, decisions, and responsibilities. At Singhammer, six building blocks structure the process from the initial definition of objectives through to stable, routine operations.

The Discovery phase serves as the starting point as part of the sales phase. It provides a reliable estimate of the project effort. Data migration begins at the start of the project and continues as a parallel workstream until shortly before go-live.

An Overview of the Six Phases of ERP Implementation:

Discovery – Clarifying Goals, Requirements, and Effort
Analysis & Process Design – Developing Target Processes
Data Migration – Preparing Data in Parallel
User Testing – Testing Real-World Business Processes
Go-Live – A Controlled Transition to Production
Hypercare – Stabilizing Operations

Phase 1 – Discovery: Define the Goals and Requirements for the ERP Project

During the Discovery phase, as part of the sales process, we define goals such as increased transparency, automation, or growth. Relevant stakeholders are involved, and the project scope is defined in terms of processes, functional areas, locations, and rollout strategy. This results in a reliable effort estimate.

An ERP Readiness Check evaluates data, processes, and organizational structure. If needed, key users receive workshops or basic training on Microsoft Dynamics 365 Business Central. We also demonstrate how DYCE addresses typical challenges related to projects, managed services, licenses, contracts, and recurring billing in a standards-based manner—without singling out specific suites or modules.

Important Questions to Ask Before Starting an ERP Project

Before the project begins, the following questions, in particular, should be answered:

What specific, measurable improvements should be made?
Which processes must be working when the ERP system goes live for the first time?
Which areas, locations, and interfaces are included in the first rollout?
What internal resources are available?
Who is authorized to make technical and business decisions?

Phase 2 – Analysis & Process Design: Optimizing Business Processes for the ERP System

We map the current processes in Sales, project management, support, license management, and billing; develop target processes; and align them with the ERP standard. Requirements are documented in the backlog, as user stories, or in a concise scope of work, and are categorized into “must-haves” and “future optimizations.”

Our industry templates and best practices closely replicate typical IT workflows using Microsoft Dynamics 365 Business Central and DYCE. Ticket and SLA processes remain in Jira Service Management; billing-related data is integrated into the ERP system.

Critical Processes in the ERP Project of an IT Company

These end-to-end processes should be examined with particular care:

Quotation, Order, and Project Setup
Project Planning, Time Tracking, and Project Management
Services and the Transfer of Billing-Related Ticket Data
Licensing, Contract, and Renewal Processes
Recurring Services and Billing
Financial Accounting and Monthly Closing

Phase 3 – Data Migration: Seamlessly Transfer Master Data and Transaction Data to the New ERP System

Right from the start of the project, an internal manager is assigned to oversee the ERP migration. As a parallel work stream, this manager oversees the analysis, implementation, and testing phases until shortly before go-live. A migration plan defines source systems, target structures, data mapping, and approvals. Typical sources include existing ERP and accounting systems, project tools, and ticket systems.

Duplicate and outdated records are cleaned up; master and transaction data—such as customers, suppliers, items, contracts, and open transactions—are organized. Test migrations, reconciliations, and approvals reduce risks. Our experience shows that contracts, recurring services, and services that have not yet been billed require special attention.

Phase 4 – User Testing: Realistically Testing the ERP System Before Go-Live

Specific test cases are derived from the most important business processes. In addition to key users, future end users who did not participate in the workshops also conduct testing. Defined feedback loops ensure that defects are documented, prioritized, resolved, and retested. The future users provide the business approval.

Which tests are essential in an ERP project?

At a minimum, the following tests should be completed before release:

End-to-End Process from Quote to Invoice
Integrated process from ticket issuance to billing
Purchases through Receipt of Goods or Billed Services
Role, Authorization, and Integration Tests
Exceptional cases, as well as incorrect or incomplete entries

Phase 5 – Go-Live: The Production Launch of the ERP System

A cutover plan outlines the timeline, steps, dependencies, and responsibilities. Before the launch, migration, integrations, and permissions are approved, and end users and administrators are trained. We closely monitor the go-live process. Depending on the project risk, the transition is supported by temporary parallel operation, a consolidated support channel, or extended availability.

Quick Checklist for the ERP Go-Live

Before the go-live release, the following points should be confirmed:

Has the final data been migrated and approved by the business unit?
Have roles, permissions, and integrations been verified?
Have key users, end users, and administrators received training?
Will key users be available during the go-live?
Are the support channels, points of contact, and escalation procedures known?

Phase 6 – Hypercare: Stabilization and Optimization After the ERP Go-Live

The duration of Hypercare depends on the project. After go-live, we coordinate daily as needed. The ticket system and dedicated points of contact help resolve issues quickly and implement minor adjustments in a controlled manner. In most cases, the operational workload decreases within the first month. Additional needs often arise during the first billing cycle or the first monthly closing.

We then fine-tune processes, document lessons learned, and hand over the system to routine operation with clear support procedures in place.

Why Does the Hypercare Phase Determine Long-Term ERP Success?

Hypercare ensures acceptance, stability, and trust in the new ERP system. At the same time, it creates a prioritized backlog for future expansion phases, further automation, and the long-term development of the ERP solution.

FAQs on ERP Projects, ERP Implementation, and ERP Go-Live

Do you still have questions about the process or the tasks involved in an ERP project? We've got the most important answers right here.

What is an ERP project?

An ERP project refers to the planned implementation, modernization, or replacement of an enterprise resource planning system. In addition to technical implementation, this includes process design, ERP migration, testing, training, ERP go-live, and stabilization.

The goal is to establish a common data and process foundation on which departments can collaborate reliably. Therefore, the success of the project is not measured solely by whether the software is up and running, but by whether the new processes work in day-to-day operations.

What's the best way to start an ERP project?

An ERP project begins with clear business objectives and prioritized end-to-end processes. Anyone looking to implement an ERP system should first identify which problems need to be solved and which results need to be achieved.

Next, we assess how the relevant processes can be mapped as closely as possible to the standard. An early effort estimate helps ensure that expectations, the budget, and available resources remain aligned.

Can an ERP system be implemented in phases?

Yes, it is possible to implement an ERP system in phases, based on processes, departments, or locations. This phased rollout reduces the workload at any given time and allows you to apply the lessons learned from the first phase to subsequent phases of expansion.

However, each stage should result in a complete, fully functional process. If only individual functions are implemented without a complete process chain, new stopgap solutions and media breaks will quickly arise.

How much time should employees set aside for an ERP project?

Internal project management requires reliable capacity for coordination, decision-making, and communication throughout the entire project duration. For key users, the workload increases particularly during the analysis, testing, and training phases; end users need time for testing and training. The extent of this workload depends on their role, the project phase, and the scope of the process. From the outset, this time should be explicitly included in the ERP project plan as a mandatory requirement, in addition to day-to-day business activities.

When will the data migration begin in the ERP project?

Data migration begins as soon as the ERP project starts, not just shortly before go-live. Data cleansing, mapping, and test migrations run in parallel with analysis, implementation, and user testing. The business units review and approve the migrated data, as they are most familiar with its significance. Shortly before the system goes live, the final ERP migration takes place based on an agreed-upon cutover plan.

What happens when new requirements arise during the ERP project?

If new requirements arise during the project, they are recorded in the backlog, technically evaluated, and prioritized. A defined change request process makes their impact on effort, budget, testing requirements, and schedule transparent. The project team then decides whether the requirement is necessary before the ERP go-live or should be included in a later phase of development. This ensures that the project scope remains manageable without losing valuable ideas.

Who needs to be represented on the ERP project team?

The ERP team should include a management sponsor, internal project management, business units, key users, end users, internal IT, and implementation partners. Each role brings a different perspective: strategy, process knowledge, technology, or practical use. For important issues, responsible parties and decision-making authority must be clearly identified. Clear roles and short decision-making paths are more important to success than having the largest possible team.

How much customization is required for an ERP implementation with Dynamics 365?

The extent of customization required depends on the maturity level of the existing processes. The goal should be to implement as much as possible using the standard software. This helps avoid costly custom programming and time-consuming release upgrades. At Singhammer, we combine Microsoft Dynamics 365 Business Central with the industry-specific solution DYCE. Based on our project experience, this allows us to cover approximately 90 percent of the industry-specific requirements of IT service providers, system integrators, and MSPs using the standard software. We use customization strategically only where it secures individual competitive advantages.

What happens after the ERP go-live?

The Hypercare phase begins immediately after the ERP go-live. During this time, the project team works closely with users, answers questions, prioritizes issues, and stabilizes the new processes. The first payroll run and the first monthly closing often require special attention. Once the system is running reliably, it is handed over to regular operation with clear support channels; further optimizations remain visible in the prioritized backlog.

How long does an ERP implementation typically take for a small or medium-sized business?

Small and medium-sized businesses should generally plan for several months to implement an ERP system. The actual duration depends on the company's size, locations, process complexity, integrations, data quality, and available internal resources.

It is not uncommon for the company’s pace to dictate the schedule more than the software does. Decisions, data approvals, and testing require dedicated resources. A phased ERP rollout can reduce complexity, provided that each phase delivers a complete and fully operational process.

What are the key factors for the success of an ERP project?

Whether an ERP project is successful does not depend on a single factor. The key lies in the interplay between the organization, the people, and the implementation. Here’s how that works in practice: Our ERP case studies and success stories from projects with IT companies.

The following factors are key to the project's success:

Objectives: Define measurable project goals and use them as a common basis for decision-making
Priorities: Consistently separate requirements relevant to go-live from later enhancements
Decisions: Define responsibilities and resolve open issues promptly
Resources: Plan for project work as a fixed internal capacity
Data: Prepare for data cleansing and migration early on
Tests: Actively involve key users and end users in testing the new processes
Communication: Communicate changes regularly, clearly, and in a way that is tailored to the target audience
