How we structure commercial relationships.
TSC Consulting works with clients across a range of commercial structures. The models below cover most engagements, but we routinely shape custom arrangements around procurement frameworks, internal budgeting cycles, and multi-year transformation roadmaps. Nothing here is rigid.
Advisory Retainer
For organizations that need an architect on call for design reviews, RFC validation, and strategic input.
- Standing access to a senior architect
- Monthly architecture review sessions
- Decision record support
- Available on monthly, annual, or multi-year terms
Suited to internal IT teams of 20+ that lack dedicated architecture capacity.
Engagement Program
For defined transformation programs with scoped deliverables.
- Full architecture lifecycle: discovery, target design, implementation oversight, governance
- Written HLDs, LLDs, and transition plans
- Embedded architect during delivery phase
- Fixed-scope or milestone-based billing
Suited to programs such as identity consolidation, cloud landing zones, DR redesigns, or M365 estate restructuring.
Architecture-as-a-Practice
For enterprises and public bodies that need a permanent architecture function without building one internally.
- Multi-year framework agreement (typically 2–5 years)
- Dedicated practice lead plus rotating specialists
- Governance board participation
- Quarterly architecture roadmap reviews
Suited to organizations under public procurement frameworks or with continuous transformation roadmaps.

Custom engagements and support contracts.
Not every engagement fits a standard model. We regularly structure custom commercial arrangements to match how our clients actually work, including:
- 01Custom-scoped engagements with hybrid fixed and time-based components
- 02Monthly support contracts for ongoing architecture oversight
- 03Annual support contracts with quarterly governance reviews
- 04Multi-year framework agreements (2–5 years) under public procurement vehicles
- 05Co-sourced delivery alongside internal IT or incumbent partners
- 06Block-hour arrangements with quarterly true-up
- 07Outcome-based engagements for clearly measurable deliverables
If you operate under a procurement framework, raamovereenkomst, or established vendor list, we adapt to your structure. Reach out with your context and we will propose a model that fits.
