Odoo promises a lot: one platform for almost your entire business. But what do users say once they have really started with it? We analysed hundreds of public reviews, forum questions and discussions - and set them alongside our own analysis of 300+ Dutch companies that switched. This is what we found.
There is a lot of noise about Odoo online, from “best decision ever” to “stay away”. We wanted to look past the isolated opinions: which patterns keep coming back when you lay a few hundred experiences side by side? Not to glorify or trash Odoo - we are an Odoo partner, so we are not neutral - but to honestly understand when Odoo works, and when it goes wrong.
Short conclusion
Odoo is broadly appreciated for its wide functionality, modularity and price-quality ratio. On the major review platforms it scores mid-high: G2 4.3/5 (over 1,200 reviews), Capterra 4.2/5 (over 1,300). At the same time, those same reviews show consistent criticism of support, hidden costs and sales pressure, the learning curve, upgrades that break customisations, and variable partner quality.
The common thread almost no one says out loud: the biggest disappointments are rarely about the software - they are about scope, expectations and the implementation approach. Odoo is not an app you just “switch on”. It is a business platform. And precisely for that reason, the approach determines whether it stays cheap and powerful, or becomes expensive and frustrating.
How we researched this
We combined two layers. Public and independent: hundreds of reviews and discussions on G2, Capterra, Trustpilot, TrustRadius, Reddit r/Odoo and the Odoo forum. Unique and our own: our own analysis of over 300 Dutch companies looking for a new ERP.
We did not copy reviews, but clustered them by theme - price, support, implementation, customisation, accounting, inventory, performance, ease of use, partner - with the sources attached. Where we cite a number, it is publicly verifiable; where that was not possible, we leave it out. We care about the pattern, not isolated anecdotes.
What users value about Odoo
The market is remarkably unanimous about the strong points:
- All-in-one, modular. Pick the apps you need; they work together on one data model. “Pick and choose what apps you need”, as one user summed it up.
- Integration that removes double entry. CRM, sales, inventory and accounting in one place - the classic escape from disconnected tools.
- Price-quality ratio. Recurring compliment: cost-effective compared to a stack of separate SaaS or a heavy enterprise ERP. One long-time user: “Odoo is literally my lowest expense.”
- Strong in manufacturing and inventory. The manufacturing app in particular gets a lot of praise on Reddit (“the manufacturing application is amazing”).
- Scales along and is open. Lots of standard functionality, a large ecosystem, and your data stays yours.
Where it hurts
Exactly that strength - breadth and flexibility - is also where it goes wrong. The recurring criticism:
- Support after go-live is inconsistent. “Once you pay, customer support disappears”, is a recurring Trustpilot sentiment. Standard support is not always set up for business-specific questions.
- Price: hidden costs and sales pressure. Reviews complain about costs that only surface after signing, price increases when changing plans, and heavy selling of “Success Packs”. Capterra’s own summary flags billing as a notable negative theme.
- Learning curve and implementation heavier than expected. “Odoo has a steep learning curve” - and without sharp choices, configuration quickly turns into customisation.
- Upgrades can break customisations. Those who customise a lot run into migration work with every version upgrade. This is a structural theme, not an incident.
- Partner quality varies widely. The independent Dutch ICT Portal even warns that many partners are “small operations with 1-2 clients” - so vet your partner well.
- Performance at scale. With lots of data or users it can get heavy; multi-company feels clunky.
We also keep the honest caveat in: part of the criticism genuinely touches the product or the company (outdated documentation, unpredictable prices, sales behaviour), separate from the approach. That is part of the picture.
The common thread: the software is rarely the problem
This is the finding that stayed with us most, and that you see back in almost every hard discussion: the biggest disappointment is attributed by the community itself to scope, expectations, buying support directly from Odoo, or missing a good partner - not to the software.
A few recurring reframes from public Reddit discussions:
- On a thread about a failed implementation, the highest-voted reply is: it has “less to do with Odoo itself and more to do with the BA you have sourced” (the internal business analyst).
- On “worst platform in 15 years” the two highest-voted replies are: get a partner - and someone who, after three years, considers it the best system on the market.
- Several experienced users: do not buy large hour packages directly from Odoo, “not to buy huge hours from Odoo directly”, but take a local partner who knows your process.
There is even a price paradox in it: Odoo is so cheap that people also expect free support - and are then disappointed. The software is broadly respected; the pain clusters around the approach.
That connects seamlessly with what we saw in our own analysis of 300+ switchers: companies almost never switch because “it could be better”, but because of a forced moment - and whoever then fails to guard scope and approach ends up in exactly the negative reviews above.
When does Odoo fit well - and when less so?
Good if: you want to get rid of disconnected systems; you have processes around sales, inventory, purchasing, manufacturing, service or e-commerce; you want to grow without constantly bolting on new software; and you accept that standardising is often smarter than rebuilding everything.
Less good if: you are looking for a plug-and-play accounting tool; you want to rebuild every existing process exactly; you have no time for involved key users; or you see ERP purely as an IT project.
Directly from Odoo, or via a partner?
Not every company immediately needs a heavy partner - it would be dishonest to claim that. But the data points one way: as soon as Odoo touches multiple processes, departments, countries, warehouses or integrations, partner quality becomes decisive. A good partner helps above all with choices: what do we do standard, what not, what in phase 1, where is customisation justified, and how do we keep upgrades safe.

Checklist: how to avoid a bad Odoo experience
- Have we done a real fit-gap before installing anything?
- Do we know which processes can run standard - and have we explicitly decided where there will be no customisation?
- Has the data migration been realistically estimated?
- Is local accounting and tax knowledge secured?
- Is there one point of contact with a mandate, and are key users involved?
- Is training part of the project, and is support after go-live arranged?
- Are we choosing a phased approach, or trying to do everything at once?
Odoo is not the right choice for every company. But if your organisation is ready for one integrated platform, Odoo is often surprisingly powerful and affordable. The real question is not “is Odoo good?” - it is “will Odoo be set up well for your business?”. That is where the difference lies between an enthusiastic review and a frustrating experience.
