You have chosen Odoo as your ERP system and now you are looking for someone to implement it for you. The website of every Dutch Odoo partner promises tailored solutions, personal attention and years of experience. Yet some projects overrun, exceed their budget or fail to deliver what you expected. The problem rarely lies in the software itself. It lies in the match between what your organisation needs and what the partner can and is willing to actually deliver. A partner that is perfect for a logistics company with fifty users is not necessarily suitable for a trading business with five employees that mainly wants to connect its webshop. In this article you work through the four criteria that make a difference: technical specialisation, way of working, transparency about costs and planning, and support after go-live.
Choose a partner with demonstrable experience in your sector or process
Odoo consists of dozens of modules that you can deploy in a thousand ways. An implementation for a manufacturer revolves around the Planning module, inventory valuation and work orders. An implementation for a service provider is about project administration, time tracking and invoicing. Both are Odoo, but they require different knowledge. So ask for references in your industry or with a comparable process. A partner that has set up ten webshops knows how to synchronise stock across channels and how to automate shipping labels. Someone who has never done that will work it out during your project — and you pay for that learning curve.
Also look at the ratio of consultants to developers. An agency with only functional consultants can set up standard processes, but gets stuck as soon as you need custom reports or an integration with external software. An agency with only developers builds what you ask for, but does not help you think about how to set up the process more intelligently. For an implementation that goes beyond the standard you need both, or at least a partner that communicates quickly and clearly with external specialists when needed.
Fact: Research by Panorama Consulting shows that 61% of ERP failures can be traced back to insufficient industry experience at the implementation partner.
Way of working: fixed price, time and materials or hybrid?
Most Odoo partners work on a time-and-materials basis: you pay by the hour and the end result depends on how many hours go into it. That works if your scope is unclear or if you want to be able to adjust along the way. The downside is that you have no guarantee of the total amount in advance. Where the project lends itself to it, we work with a fixed price, based on a clear scope and a detailed analysis up front. That requires more preparation, but gives you certainty. For projects where the scope is still vague or where you want delivery in phases, we combine both: a fixed amount for the analysis and configuration, time and materials for customisation and training.
Ask the partner how they handle scope changes. Every project involves changes along the way, but not every partner communicates clearly about them. Some agencies charge for every change without first giving a new price indication. Others keep some budget headroom for small changes and only consult you on larger deviations. Agree the procedure in advance: what falls within the original scope, what does not, and how and when do you receive a revised quote?
Where it goes wrong in practice
Pitfall 1: The partner knows the software, but not your process
An implementation partner used to standard processes often follows the logic of the software rather than the logic of your business. You get a working system, but it does not match the way you work. Cause: too little time spent on analysis and process design. What to do about it: insist on an intake phase in which the consultant maps your process and reports back on how they intend to translate it into Odoo, including the deviations and their consequences. Only once you understand that translation do you approve the build.
Pitfall 2: No clear communication about dependencies
Many implementations are delayed because the partner is waiting for information, test data or a decision from you, but does not say so explicitly. You think the project is progressing; the partner is at a standstill. Cause: no clear agreements about who delivers what and when. What to do about it: ask for a project plan with milestones and dependencies. Make sure there is weekly contact, for example a fixed meeting on Monday or Thursday, so that blockers come to light quickly.
Pitfall 3: Too little attention to data migration
Partners often underestimate the time data migration takes. Your old system contains a thousand customers, ten thousand products and five years of order history. That data has to be cleaned, structured and imported, and it rarely goes right in one go. Cause: data migration is only tackled late in the project, when it turns out that the old data is not clean enough. What to do about it: discuss data migration in the intake phase and set aside separate time and budget for it. Do a trial import halfway through the project, so that you spot problems early.
Transparency about costs and lead time
Ask for an itemised quote. An amount of €15,000 for an Odoo implementation says little if you do not know how many hours it contains, for which modules, and what is excluded. A good quote breaks it down: analysis and design, configuration per module, data migration, training, documentation and aftercare. That way you can see where the budget goes and make choices. Want to migrate the data yourself? That saves a few thousand euros. No need for customisation? Then the implementation can be considerably faster.
Also look at the lead time. An implementation of core modules for an organisation with ten users takes six to ten weeks on average, depending on the complexity of your processes and the availability of your team. An implementation with customisation, integrations and migration of legacy data can take three to six months. Promises of "live within four weeks" sound attractive, but are only achievable if you can manage with standard settings and are willing to adapt your process to the software. Ask about the critical dependencies and the schedule for the main milestones, such as the delivery of the test environment and the go-live.
Support after go-live: who solves problems?
An implementation does not stop at go-live. In the first weeks after launch you will run into questions: how do you post a credit note, how do you change a sales price, why is that email not arriving? Some partners offer a month of free aftercare; others charge by the hour from day one. Ask in advance how support is arranged: by email, phone or ticket, with what response time, and at what rate. Also check whether you have a fixed point of contact or speak to a different consultant each time.
Think beyond the first month. Odoo releases a new version twice a year with improvements and new features. Upgrading is not mandatory, but if you have custom modules you need to test them and possibly adapt them. Ask the partner how they handle upgrades: do they take the initiative, or do you have to ask? What does it cost? And how long does support remain available for an old version? A partner that thinks ahead about upgrades and technical debt prevents you from being stuck on an outdated, unsupported version two years from now.
Note: A support contract costs on average 10-15% of the implementation costs per year, depending on the agreed response time and availability.
Book an introduction first, not a quote
The best way to test a partner is an intake meeting. Not to get a quote straight away, but to see whether the partner understands your process, asks critical questions and proposes alternatives. A good consultant asks why you are choosing Odoo, where your current system falls short, which processes cause the most friction and who will be working with it. Someone who can give you a quote within half an hour has not asked enough questions. Arrange meetings with two or three parties and compare not just the price, but also the approach and the rapport. You will be working together for months; if communication is already difficult now, it will not get better later.
During that meeting, ask for concrete examples: how did they solve a comparable process before, what went wrong and what did they learn from it? A partner that is open about pitfalls and failures inspires more confidence than one that makes everything look easy. Finally, check the reviews on Google or other platforms and ask whether you can speak to an existing client. Most partners welcome this, and it gives you a realistic picture of how the project runs and what the collaboration feels like.
