03 — Engagement Models

How we work.

Model 01

Fixed-Price Milestones

Scoped project delivered against a defined statement of work. Milestone-based billing (commonly 40% / 30% / 30%). Best when the outcome is well-defined and the client wants predictable cost.

Best for: Feature builds, MVPs, scoped rebuilds
Model 02

Weekly Retainer

Dedicated weekly capacity against a prioritized backlog. Flexible scope, predictable weekly spend, and a standing channel for ongoing work. Minimum four-week commitment.

Best for: Ongoing product development, support
Model 03

Time & Materials

Hourly billing against a not-to-exceed cap. Used for discovery phases, unscoped investigation, or emergency work where fixed-price isn't practical. Transparent time reporting.

Best for: Discovery, audits, short-cycle work
04 — Process

From kickoff to launch.

01

Discovery

30–60 minute intro call. We review the goal, constraints, timeline, and success criteria. Follow-up written brief within 48 hours — shared scope, assumptions, and proposed engagement model.

02

Scope & SOW

Statement of work drafted against the MSA. Fixed milestones, acceptance criteria, deliverables, and payment schedule. Signed digitally before any work begins.

03

Build

Weekly written updates. Shared repo and project board. Staging deploys for every feature. Client has live access throughout — no black-box development.

04

Acceptance & Launch

Each milestone reviewed against its acceptance criteria. Launch includes production deploy, monitoring, and handoff documentation. Final invoice on acceptance.

05

Post-Launch

30-day warranty on delivered work. Optional retainer for ongoing support, feature development, or monitoring. All code, credentials, and documentation transferred to the client.
