Engagement model
Fixed scope, clear milestones
Add-in projects fail when scope is vague. Our Discovery, Build, and Scale packages define deliverables, timeline, and acceptance criteria up front — so you know what you are buying before engineering starts.
Discovery is ideal for feasibility and prototypes. Build covers end-to-end development and store submission support. Scale provides ongoing sprint capacity for integrations and iterations.
Frequently asked questions
- What affects the final quote?
- Number of Office apps, Graph or third-party integrations, AI features, deployment model, and review cycles with InfoSec are the main drivers.
- Is Discovery required before Build?
- Not always — if you have a detailed spec we can quote Build directly. Discovery is recommended when feasibility or stakeholder buy-in is still open.
- Do you offer hourly work?
- We prefer fixed-scope packages for predictability. Scale engagements use sprint-based capacity with agreed backlogs.
