Truviate never edits the draft invoice. The review tells you what is verified, what needs a decision, and why.

What the agreement said

$6,000 monthly retainer including 40 hours; $175/hour beyond. Approved third-party costs at cost. Milestone 3 billable after deployment and written acceptance.

What was delivered

48.5 approved hours across 20 time entries, a $380 Getty Images licence approved in advance, and release v2.4.0 deployed on 28 August — acceptance email still outstanding.

What the draft invoice showed

Two lines totalling $12,000: the retainer and the accepted design-system milestone. No overage, no expense, no deployment milestone.
