Two frames at 375 × 760 covering the PM's full T&M draft flow: list of in-progress invoice drafts, then drill into a draft to edit labor + materials and send.
Cards replace the desktop two-pane layout. Each card surfaces what a PM scans for in the field: customer, service date + call type, $ total, and a colored margin chip (green >25%, amber 15–25%, red <15%) so unprofitable drafts jump out before the PM sends them. Filter pills mirror the QB invoice lifecycle. Tap a card to edit (Frame 2).
Two collapsible sections — Labor and Materials — replace the desktop two-table layout. Labor rows are read-only (sourced from time entries); materials rows expose the inline margin %, the only field a PM actually changes. The sticky bottom strip keeps the running total visible and puts Save draft + Send invoice one thumb-tap away.
