The problem
What gets in the way
Odoo is often chosen because it covers a lot for relatively little money, and because it is open source: you are not tied to a single supplier and you decide where it runs.
You are behind on releases and afraid to update
Updating feels risky because nobody knows what will break. Meanwhile the gap grows and the step gets bigger; it's the most common reason an Odoo environment gets stuck.
Your custom work is tangled into the standard
Changes were made directly in the standard modules instead of in a module of their own. Every update clashes with that and the cost keeps rising.
Your previous supplier has moved on
There's an environment that works, but nobody knows any more what's in it, what is custom and what happens when you touch something.
Your accounting system and Odoo know nothing about each other
Data is exported, edited and loaded back in because there's no working integration. That costs time and introduces errors at every handover.

How we look at it
All of that is true, but only for as long as your environment stays maintained. Where it goes wrong is almost always the same pattern: custom work gets built on top of the standard modules, new releases come out, and that custom work does not come along by itself. Skip a few releases and updating is no longer an afternoon's work.

The standard has moved on, your custom work has not, and the gap has to be bridged by hand. The longer you wait, the wider that gap and the more expensive the catch-up. So with Odoo we also look at how maintainable it will be in two years.
That means solving as much as possible within the standard, keeping custom work small and clearly bounded, and building it so an upgrade stays manageable. Sometimes it means advising you not to put something in Odoo at all.
What we build
How we help
We pick the right modules and set them up around your process, with as little custom work as possible. What you solve within the standard doesn't have to be migrated later.
What Odoo doesn't offer we build as a separate module. That keeps it separate and clear at every upgrade.
We connect Odoo to your webshop, your accounting or your own application, and make it visible when a synchronisation fails.
From an environment that's fallen behind to a current one, including your custom modules. We first map what it will cost.
We find out what's really running, which custom work is active and where the risks are. Then we make it maintainable again, so you can move on without the previous party.

Our approach
From idea to working software in four phases
Every project runs through the same four phases, so you always know what's happening, what comes next and what it costs, from first call to live software, usually in weeks rather than months.
- 01Phase 1Free intake
Understand & analyse
Everything starts with a good conversation. We map your goals, processes and the bottlenecks worth solving: no sales pitch, just an honest read on where the biggest win sits.

- 02Phase 2Free blueprint
Blueprint & quote
We turn the analysis into a blueprint: a clear plan showing exactly which steps we'll take and why, paired with one fixed quote. You know up front precisely what we build, what it costs and when it's done, so the bill can't surprise you afterwards. And that blueprint is free and without obligation.

- 03Phase 3Prototype in days
Build, test & deploy
Then we build, in short iterations. You see a working prototype in days and a finished product in weeks. We work on a modern, AI-native and secure stack, with data protection and GDPR in mind from day one.

- 04Phase 4100% your code
Implement & optimise
We launch, hand over the full codebase and keep improving on your terms. You get 100% ownership of the code we write. Hosting and maintenance are optional.

What you always get
Fixed price
Agreed up front.
100% code ownership
Your code, fully yours.
Live in weeks
Prototypes in days, finished in weeks.
Modern & secure
A scalable stack that always integrates with the latest tech. Secured by our in-house cybersecurity experts.
Tools & tech
We build on the tech that fits you
We build on the technology that fits you best. If you already work with a certain stack (.NET, PHP or something else), we simply build on it. Starting fresh? Then we draw on years of experience to pick the technology that's strongest for your situation. You only migrate when it gains you something.
- A working Odoo environment, configured around your process
- Custom work as separate, self-contained modules
- Source code is and stays yours, documented and transferable
- Documentation of what was changed and why
- A migration path so you can stay current
- Fixed price per phase, agreed up front
Faster Delivery. Fixed price. Forever your code.
Traditional agencies make software feel risky. Topdevs makes the project clear before we build.
Frequently asked questions
How does an Odoo implementation work?
We start by mapping your processes and decide per area whether the standard module will do or custom work is needed; we keep the latter as small as we can. Then we configure Odoo, move your data over, build the integrations with the systems that stay, and test with the people who'll use it. Go-live happens in phases, so you don't switch everything over in one day. And at handover we agree how your environment keeps up with new releases, because that's where Odoo usually goes wrong.
Why does an Odoo environment need to be kept current?
Odoo ships new releases regularly, and your custom modules do not come along automatically. Skip a few releases and the standard has moved on while your custom work stood still, and that difference has to be bridged by hand. The longer you wait, the wider the gap and the more expensive the catch-up. Staying current in small steps is almost always cheaper than one big leap.
Can you take over an existing Odoo environment?
Yes. We start by mapping what is running: which modules are standard, what custom work sits in there, and whether that custom work is cleanly separated or was changed directly inside the standard. That last point largely determines what updating will cost. You then get a plan with priorities.
Community or Enterprise, which should I choose?
That depends on which modules you need and whether you would otherwise have to build that functionality yourself. Enterprise includes modules Community does not have; if that is exactly what you need, building it yourself is usually more expensive than the licence. If you do not need those modules, Community is a perfectly good basis. We work that through up front, so you don't end up with the heaviest option by default.
Is Odoo suitable for my distinguishing process?
For your administration, sales, inventory and projects, usually yes. For the process that sets you apart from competitors, often not, because you end up building so much custom work on top of the standard that you get the drawbacks of both worlds. A common split is Odoo for the backbone and a separate application for your core, cleanly integrated. We will say honestly if that works out better in your case.
Am I tied to you if you build my Odoo?
No. Odoo is open source and your custom modules are and stay yours, documented and transferable. Another party can take it over, and you decide where the environment runs. That is exactly why we also take over other people's Odoo: it should be possible.
What does an Odoo project cost?
That depends mainly on how much custom work you need and whether an existing environment has to be taken over or updated. So we start with an assessment and then give a fixed price per phase, so you are not on a time-and-materials basis. For a takeover that assessment matters even more, because the state of the existing custom work drives most of the cost.
