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.
FAQ
Frequently Asked Questions
Everything you need to know about our services, process, and solutions.
Number of Office apps, Graph or third-party integrations, AI features, deployment model, and review cycles with InfoSec are the main drivers.
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.
We prefer fixed-scope packages for predictability. Scale engagements use sprint-based capacity with agreed backlogs.
