Where Your Development Budget Actually Goes
For many innovative companies in the Netherlands, the WBSO (Wet Bevordering Speur- en Ontwikkelingswerk)
is a key incentive that lowers the cost of developing new technology. But one important reality often gets overlooked:
Not all development work is R&D.
Understanding where your development budget actually goes helps companies structure projects more efficiently both technically and financially.
Let’s break it down.
Understanding the WBSO Benefit
The WBSO is a Dutch tax credit that reduces wage tax for employees performing research and development work. This effectively lowers the cost of innovation projects for companies building new technology.
Example Scenario
Consider a BV with:
- 2 R&D engineers
- 2,000 approved WBSO hours for the year
- RVO calculated hourly wage: €30
Total R&D wage base:
2,000 hours × €30 = €60,000Approximate WBSO benefit:
36% × €60,000 ≈ €21,600 tax reductionThis means the government effectively covers a significant portion of experimental development costs. However, this only applies to qualifying R&D activities.
The Reality
In most real projects, the distribution of work looks roughly like this:
| Category | Typical Share | WBSO Eligibility |
|---|---|---|
| Experimental R&D | 20–30% | Fully eligible |
| Implementation & Development | 50–60% | Partially eligible |
| Maintenance & Optimization | 10–20% | Usually not eligible |
1. Experimental R&D
This is the core of WBSO that includes:
- Designing a new algorithm
- Solving technical bottlenecks
- Creating experimental architectures
- Developing proof-of-concept systems
These activities involve technical uncertainty, which is exactly what the WBSO scheme is designed to support.
2. Implementation & Development
This category is where most development hours actually go. Typical activities include:
- Implementing features
- Building APIs
- UI development
- Integrating systems
- Writing production-ready code
While these tasks are essential, many of them do not qualify as WBSO, because they involve integrations rather than solving new technical challenges.
3. Maintenance & Optimization
Examples include:
- Bug fixing
- Performance tuning
- Infrastructure maintenance
- Routine refactoring
These are critical to software quality but generally fall outside the scope of WBSO unless it opens a technically new solutions.
How Companies Handle the Non-R&D Work
Because a large portion of development falls outside WBSO eligibility, many companies adopt hybrid delivery models. Common strategies include:
- Hiring remote engineers
- Working with freelancers
- Partnering with managed development teams
These approaches allow companies to keep core R&D internal while scaling the rest of the development work efficiently.
1. Remote Employees
Remote employees work as part of your internal team but from different locations.
Advantages
- Integrated into company processes
- Long-term knowledge retention
- Lower hiring constraints globally
Challenges
- Requires internal management
- Time zone coordination
- Onboarding overhead
Remote employees still need the same project leadership and coordination as in-house teams.
2. Freelancers
Freelancers are often used for short-term or specialized tasks.
Advantages
- Flexible hiring
- Fast onboarding
- Pay only for work delivered
Challenges
- Limited long-term commitment
- Availability varies
- Knowledge continuity can be difficult
Freelancers work best when companies need specific expertise for a limited duration.
3. Managed Development Teams (Outsourcing)
Many companies eventually move toward outsourced development teams.
In this model, a provider manages the engineering team while the client focuses on product direction.
Advantages
- Access to experienced engineers globally
- Lower recruitment and operational overhead
- Faster scaling of development capacity
For companies with strong product leadership internally, this model often becomes the most scalable option.
Around 72% of companies outsource software development activities such as application and web development.
A Common Hybrid Strategy
Many technology companies structure projects like this:
| Work Type | Ownership |
|---|---|
| Core R&D (WBSO eligible) | Internal engineering team |
| Feature implementation | Remote engineers / managed teams |
| Maintenance & scaling | Outsourced or shared teams |
This allows companies to:
- Maximize WBSO benefits
- Accelerate development
- Optimize engineering costs
The Key Takeaway
WBSO significantly reduces the cost of innovation, but it only covers a portion of the total development effort.
In reality:
- 20–30% of work is experimental R&D
- 70–80% is engineering, implementation, and operations
Companies that understand this distribution can structure their teams more strategically — keeping
innovation in-house while scaling the rest of development through flexible talent models.
