Buitengewone Accountants
From keeping up to leading the way
Buitengewone Accountants is an accounting and audit firm with four offices in the Achterhoek region: Doetinchem, Gaanderen, Winterswijk and Lichtenvoorde. With around fifty employees, they serve a wide range of clients, from self-employed professionals just starting out to growing SMEs. They take care of everything from A to Z, provide periodic guidance, or support clients with their annual accounts. Always built around the same core services: accounting work, tax advice, business advice and payroll processing. But Buitengewone Accountants looks beyond the present. They stand for a fundamental shift in their industry, and they want to lead the way.

Faster onboarding, less work
Results at a glance
Buitengewone Accountants has laid a new foundation—for themselves and for their clients. With Odoo as their central platform, they can let clients start small and grow with them without ever having to switch systems. The first clients have already been migrated, onboarding is moving faster, and the administrative workload has noticeably decreased.
This is more than a technical implementation. It is a strategic choice: as the first accounting firm in the Eastern Netherlands region to be Odoo-certified, they are putting forward an offering that truly helps their clients move ahead. And them too.
A fresh perspective
The accounting sector is changing. Clients expect more for less. AI is changing how audit work gets done. And the traditional software packages firms use are not growing along with the businesses they serve. That last point was a creeping problem. The existing software mainly supported the financial side, but it did not grow with clients' broader needs or the firm's ambitions. That created a recurring pattern: as soon as clients grew larger or more independent, they ran into limits in their package and switched to something else. As a result, Buitengewone Accountants lost not only efficiency, but also control over the client relationship.
Together, we zoomed out. What does this market really need? How can an accounting firm stay relevant in a world where digitization and AI are becoming the norm? And how do you give clients a foundation that won't start to feel restrictive again after just a few years? That is where the heart of this case emerged: not simply introducing a new system, but building a scalable platform that allows Buitengewone Accountants to lead the sector's digital transformation.
First vision, then technology
We didn’t start with the software, but with the movement Buitengewone Accountants wants to make. What does modern service look like? What role do you want to play as a firm in your clients’ growth? And how do you ensure that you’re not just providing administrative support, but also staying strategically relevant?
From those questions, a clear direction emerged. Clients need to be able to start small, without immediately ending up in a heavy package. But they also need to be able to grow, without having to choose different software again. That calls for a platform that moves with the business and, at the same time, remains intuitive enough for everyday use.
We chose:
Start small and build trust, not lock everything down in advance
Shape it together: how do you onboard clients, step by step
Ownership with the team, so they can guide clients themselves
Digital freedom as a starting point: clients who learn to understand and use the platform
The challenge was familiar: accountants seek certainty. They want to know everything before they begin. That is their strength as professionals, but in a change process it can hold things back. By starting small and showing value quickly, we built the trust needed to move forward faster.
Everything on one platform
Odoo becomes the central hub for Buitengewone Accountants and their clients:
Clients start small with the free starter option and grow modularly: finance first, then sales, webshop, inventory, shipping
Fast onboarding: a new client is up and running in no time, without technical barriers
Less handling: accounting support takes fewer hours, so more clients can be served in the same time
Peppol support: e-invoicing that was missing in other packages is already available here
AI as the next step checking annual accounts with AI, automating internal processes: the foundation is already in place
The internal rollout at Buitengewone Accountants themselves, with their own processes on Odoo, is the next phase. A logical step: if you know the platform from the outside, you can make even stronger use of it from the inside.
Customers who keep coming back
Because the platform grows with you, customers no longer need to switch. The relationship with Buitengewone Accountants stays intact, even as a business grows from self-employed to SME.
Faster onboarding, less work
We've migrated the first customers. Onboarding is going faster, and the administrative work per customer has noticeably decreased. We can now serve more customers with the same team.
A frontrunner in the region
As the first accounting firm in Eastern Netherlands, Buitengewone Accountants positions itself as the partner for entrepreneurs who want to grow digitally.
What makes this collaboration so special
We came in with questions about direction. What does a business owner expect from their accountant three years from now? What is needed to make that expectation a reality? How does an accounting firm stay relevant in a market that is fundamentally changing?
Only when those questions had been answered did we start building. Not software, but an offering. A way of working that sets Buitengewone Accountants apart and genuinely helps their clients move forward.
Review
With Buitengewone Accountants, we’re not just building a new system, but a platform that helps them continue guiding their clients as they grow. That’s where the real value lies.
