Strategic delivery decisions for D365FO: in-house, outsourcing or hybrid?
The question of “in-house or outsourcing” is not about trends — it is about economics, risk exposure, and long-term operational resilience. This becomes particularly visible in areas with scarce expertise, such as development and support of Dynamics 365 Finance & Operations (D365FO).
Below is a concise overview of the factors that influence the strategic choice of a delivery model, followed by a simplified financial model comparing the cost of one D365FO developer in Austria.
Where outsourcing provides advantages
1️⃣ Reduced time-to-hire
The IT talent market in the EU remains highly competitive. Finding a qualified D365FO developer may take months, along with all related recruitment costs. Outsourcing enables access to an experienced specialist or a complete team within weeks.
2️⃣ Cost predictability
In-house staffing includes multiple mandatory cost components - many of them unpredictable or not immediately visible:
- employee compensation components (paid leave, sick leave, bonuses)
- workplace setup, hardware, licenses
- training, onboarding, mentoring
- administrative overhead
- statutory employer obligations (e.g., severance)
- periods of underutilization
Outsourcing operates on a predefined budget and eliminates most “hidden” costs.
3️⃣ Scalability and flexibility
With outsourcing:
- a specialist can be replaced without delays or legal risks
- teams can be scaled up or down depending on workload
- the service volume can be adjusted to project requirements
This makes the model more resilient to market fluctuations and internal demand cycles. However, scalability depends on the provider’s resource pool - not all vendors maintain sufficient bench capacity or specialized roles.
4️⃣ Access to broader expertise
An outsourcing provider offers more than a single developer - it provides access to an internal ecosystem of competencies:
- architects and DevOps specialists
- integration and cross-technology expertise
- experience from dozens of projects across industries
- awareness of typical pitfalls and proven patterns
Such breadth is rarely available in mid-sized corporate IT departments. The provider’s depth of internal expertise should be treated as a critical criterion when assessing outsourcing partners.
5️⃣ Ongoing competency development
For specialized outsourcing companies, maintaining up-to-date skills is a core business function. Providers systematically invest in:
- employee certifications on the product
- internal knowledge exchange
- monitoring of roadmap and platform changes
Most internal IT departments cannot sustain this level of investment or the pace of capability renewal, particularly for complex and rapidly evolving cloud ERP platforms.
Where in-house teams are stronger
1️⃣ Retaining critical internal expertise
In-house teams ensure:
- deep understanding of domain logic and business processes
- historical context of architectural decisions
Many companies underestimate the risk of expertise loss when key employees leave. Without mature knowledge-management processes, an in-house model becomes as risky as outsourcing. By contrast, mature outsourcing providers typically maintain documentation and structured knowledge transfer practices because service quality directly depends on it.
2️⃣ Business responsiveness
Advantages of an in-house team:
- embeddedness in corporate culture and business context
- direct communication channels without intermediaries
- ability to shift priorities quickly
For many European organizations, direct personal interaction remains a key factor in successful change delivery. At the same time, combining such interaction with the structured practices typical of outsourcing models can make internal communication more transparent, manageable, and less dependent on individual contributors.
3️⃣ Vendor independence
Benefits of an in-house approach:
- full control over architecture and core processes
- independence in technology and governance decisions
- direct ownership of access to sensitive data
This level of control depends entirely on the competencies of internal staff and the maturity of established processes. For non-critical areas, selectively relying on external providers can actually help the organization stay focused on the activities that truly create business value.
4️⃣ Trust and predictability
Advantages of an in-house team:
- deeper understanding of actual competencies and limitations
- transparent oversight of work execution
- informal relationships that accelerate decision-making and encourage initiative
Working with outsourcing teams requires more formalized governance, contract management, and regular compliance and contract-fulfilment checks — which adds operational overhead on the client side.
Which model works best?
(Austria, D365FO Developer - indicative model for order-of-magnitude analysis)
A direct financial comparison between an in-house developer and an outsourced specialist is inherently imprecise. An internal employee typically divides their time between core development tasks and non-development activities such as internal meetings, administrative duties, and organizational processes, in addition to taking paid leave. As a result, the amount of effective working time available for project-specific tasks is significantly reduced.
An outsourced developer, by contrast, is billed solely for targeted, project-relevant work, with no overhead from non-productive activities. To ensure a consistent and realistic comparison between the two models, we assume that an in-house D365FO specialist provides an effective workload of approximately 75% of total working time (~120 productive hours per month).
Step 1: In-house D365FO developer
Market data (vacancies, industry insights):
- Average gross salary: €70,000
- Employer social contributions: ~30%
- Total direct cost: ~€91,000
Adding indirect costs (equipment, licenses, training, sick leave, administration, etc.):
- Additional overhead: ~15%
- Total Cost of Ownership (TCO): ~€105,000 per year
Step 2: Outsourced D365FO developer
Senior specialist from nearshore office:
- Hourly rate: approx. €90
- Productive hours per month: ~120
- Estimated annual costcost: ~€130,000
In this simplified model, outsourcing appears more expensive due to the higher hourly rates of external senior specialists. However, the model intentionally omits several critical factors that vary significantly across organizations and, in practice, often shift the economics in favor of outsourcing.
Step 3: What changes the equation?
1️⃣ Utilisation
Internal teams rarely achieve high project utilisation. A significant portion of time is spent on internal communication, meetings, support and contextual tasks.
Studies (e.g., Microsoft developer time-allocation research) estimate that only 40-60% of a developer’s time is spent on core development work - and this is within a highly mature engineering environment. Based on our experience, utilisation in corporate IT teams often does not exceed 40%.
In outsourcing companies, utilisation is one of the key operational management metrics. Through structured planning, clear role allocation, and disciplined time tracking, utilisation levels often reach 70–80% over a full annual cycle.
This utilisation gap translates into hundreds of hours of productive work per year and is one of the factors that significantly impact the overall economics of choosing a delivery model.
2️⃣ Cost of risks
- A hiring mistake results in sunk costs for recruitment, onboarding, and severance, as well as business impact due to delays or cancellations of projects.
- Employee departures for personal reasons lead to project slowdowns, loss of critical expertise, and reduced productivity.
- Dependence on individual specialists (bottlenecks) slows down change delivery, limits team throughput, and increases the total cost of system ownership.
- Insufficient competencies increase the risk of costly architectural errors, rework, and even business disruptions.
- Workload volatility creates resource instability: internal teams cannot scale quickly, resulting either in idle costs during low-demand periods or in postponed and cancelled initiatives during peak resource shortages.
In practice, the most effective and resilient approach for mature organizations is a hybrid model combining the strengths of in-house expertise with the flexibility and breadth of external providers.
Retained in-house:
- Enterprise architecture - maintaining strategic control over target IT landscape, data, and direction of the platform.
- Key Experts and Domain Knowledge - deep process understanding and organizational context.
- Product and Business Analysis - managing priorities, engaging with the business, defining requirements, and evaluating outcomes.
Outsourced:
- Depth and Breadth of Expertise - access to DevOps, solution architects, rare specialists, and non-core competencies.
- Scalability - rapid team expansion for projects, seasonal peaks, or new initiatives without lengthy hiring cycles.
- Operational resilience - coverage of vacations, turnover, illness, bottlenecks, and single-point-of-failure risks.
- Operational efficiency - higher productivity through managed utilisation, standardized processes, SLAs, and optimal allocation of tasks across specialized roles.
