Paying for a large project in one lump sum concentrates risk. If it is all paid up front, the client is exposed; if it is all paid at the end, the freelancer is. Milestones split the work — and the money — into smaller, verifiable chunks so risk is shared evenly across the timeline.
Each milestone has a clear deliverable and an amount. When the deliverable is approved, that milestone's funds release. If a disagreement arises, it is limited to the current stage rather than the entire contract, which makes it far easier to resolve.
KAZI implements milestone protection through escrow: the client funds the project into a protected balance, milestones are defined against the work, and each one releases on approval — connecting the project plan, the approvals and the payments in one place.
