In our previous article, we explained why a business needs an ERP system and what benefits it provides: transparency, control, efficiency, and scalability. But understanding why is only the first step. Real transformation begins when a company moves on to how.
At Codoo ERP, we specialize in implementing ERP systems based on Odoo — a flexible, modern platform designed for small and medium-sized businesses, as well as companies ready to scale.
If you’re new to Odoo or wondering whether it’s right for your business, we recommend reading our article “What Is Odoo” — a simple, example-driven guide to how the system works and what makes it different from other solutions.
In this article, we’ll walk you through the ERP implementation process step by step — what methodologies are used, what to plan ahead, and how to avoid common mistakes.
Why ERP Implementation Is a Project, Not Just Software Installation
ERP is not simply a program — it’s a new operating system for your business, covering finance, sales, warehousing, production, and analytics.
The misconception that ERP implementation is just “buy and install” often leads to disappointment. In reality, implementing ERP means business transformation — it requires rethinking processes, engaging the team, and taking a strategic approach.
You can’t just “plug in” an ERP; it needs to be embedded into the company’s culture. That’s why every project is a partnership between the integrator and the client — focused not only on what to implement but also why.
Step 1: Business Process Analysis
The first and most critical stage is diagnosing the current state of the company.
At Codoo ERP, every project begins with a deep business process analysis. We study how the company operates in practice: where resource losses occur, where data is duplicated, what tasks are manual, and where decisions rely on “gut feeling.”
Imagine this: the sales department manages clients in Excel, accounting works in 1C, and warehouse staff record stock levels in a notebook. As long as things run smoothly, the system seems fine — but once one key person goes on vacation, everything breaks down.
ERP isn’t meant to digitalize the chaos — its purpose is to create a single, logical data flow.
At this stage, we build a business process map — a visual diagram showing how information moves between departments and where inefficiencies arise.
Then comes the technical specification (TS) — a document outlining goals, priorities, and required system features. It becomes the roadmap for the entire implementation team.
Step 2: Configuration and Customization
Once the process map is ready, the technical phase begins. But ERP implementation isn’t about mechanically configuring modules — it’s about adapting the system to reflect the unique logic of each business.
Different businesses have different priorities:
- Manufacturers need cost tracking and material flow management.
- Retailers focus on stock visibility and multi-currency accounting.
- Service companies value workload tracking and project profitability.
That’s why ERP must “speak the client’s language.”
At this stage, we:
- Configure core modules (CRM, sales, procurement, manufacturing, finance, etc.)
- Create custom reports and dashboards
- Integrate with banks, marketplaces, accounting systems, and CRMs
- Adapt the interface to the company’s real workflows
For example, for an e-commerce client, we integrated the website, warehouse, and payment systems — and for the first time, they saw a complete view of sales in one window.
Odoo allows solutions to scale without losing flexibility. We configure each system so it can evolve alongside the business — not limit it.
Step 3: Staff Training and Testing
A system only works when people actually use it. That’s why training and testing are mandatory ERP implementation stages.
We train two key groups:
- Managers — to use analytics and reports for decision-making.
- Employees — to see how ERP simplifies their daily tasks and reduces routine.
It’s not just about showing “where to click” — it’s about instilling the ERP mindset: visibility, accountability, and reduced human error.
After training, the system enters testing mode — using real-world scenarios.
For example, in one project, managers were accidentally closing orders without dispatching them. After testing, we added confirmation steps — and the issue disappeared.
Testing is valuable not only for technical debugging but also for confirming that the team truly understands the new workflow logic.
Step 4: Launch and Ongoing Support
After successful testing comes Go Live — the official system launch. From this moment, the company adopts a new management model: data becomes centralized, departments operate synchronously, and executives gain real-time insight.
But remember: launch isn’t the finish line — it’s the beginning of a new phase.
During the first weeks, the system adapts, users get accustomed, and improvement ideas appear. This is why post-launch support is a vital part of every ERP implementation.
At Codoo ERP, we continue to support clients after go-live by:
- Helping fine-tune reports
- Adding new functionalities
- Advising on process optimization
This is when businesses start seeing tangible results:
- Order processing speeds up
- Financial errors decrease
- Management decisions become faster and more data-driven
ERP Implementation Methodologies
There are several implementation methodologies, and the right choice directly affects project timeframes, budget, and results.
Waterfall (Cascade Model)
A traditional linear model: Analysis → Configuration → Testing → Launch.
Best for companies with stable processes and fixed requirements.
- Advantages: clarity, predictability, and structured control.
- Disadvantages: hard to make changes in later stages.
Agile (Flexible Model)
Agile uses an incremental approach — modules are launched step by step. The team sees results quickly and can make adjustments along the way.
- Advantages: flexibility, speed, and team involvement.
- Disadvantages: harder to forecast total project time or cost.
MVP (Minimum Viable Product) Approach
An MVP version launches only the essential functionality to test hypotheses and gather user feedback.
Best for companies transitioning from Excel or starting small with minimal risk.
- Advantage: fast start and scalable evolution.
Codoo ERP’s Practical Insights
Our 7+ years of Odoo ERP experience have proven one thing: success depends not only on technology but on philosophy.
1. Start with goals, not modules
ERP isn’t an IT toy — it’s a business tool. Define what you want to improve first: financial visibility, sales speed, inventory control. When the goal is clear, solutions fall into place.
2. Don’t copy old processes
ERP is your chance to rethink. If managers used to duplicate data in three tables, don’t look for a faster way to do that — remove the redundancy entirely.
As Peter Drucker said: “There is nothing so useless as doing efficiently that which should not be done at all.”
3. Engage your team early
The sooner employees get involved, the easier it will be for them to accept the system. When people are heard, they become allies, not resistors.
4. Implement step by step
Phased implementation is not a compromise but a stability strategy. Start with key departments, evaluate results, then expand.
5. Plan for post-launch support
The project doesn’t end at launch. After a few months, new ideas and needs arise. A reliable integrator always provides a support “tail” — that’s when ERP delivers maximum value.

ERP as a Growth Tool
Implementing an ERP system is not just automation — it’s a new management culture. A company that sees all its data in one place can make faster decisions, work more transparently, and grow sustainably.
ERP doesn’t replace entrepreneurial intuition — it strengthens it, by giving leaders solid facts to rely on. That’s why ERP is an investment in maturity, efficiency, and scalable growth.
