User Flows
FRD7 – Date filter selection flow, KPI card display, chart interaction (hover tooltips, legend toggle), Discount Code Usage table display, Export PDF flow

Functional Logic
FRD7 – Date filter logic (This Quarter default; presets: Today, Last 7/30/90/365 Days, Custom Range with end > start validation); KPI card calculations (Total Revenue = Subscription + Extra Seat + Transaction Fees; New Paid Subscribers count; Churn Rate = cancelled/total × 100%; CAC = 'Coming in v2' placeholder); Total Revenue Overview chart (line + bar, 3 data series: Subscription, Extra Seat, Transaction Fees); Revenue by Subscriptions chart (stacked bar, 4 plan types); Revenue by Service Types chart (pie, 4 agency types); Discount Code Usage table (all codes including deleted, columns: Code, Type, Discount, Usage Count, Revenue Impact, Status; Revenue Impact = sum of discounts applied); PDF export (filename: Pixally_Reports_[StartDate]_to_[EndDate].pdf, contains all KPI cards + 3 charts + discount table)

Acceptance Criteria
FRD7 – Default date filter is 'This Quarter' on page load; all presets and custom range filter KPI cards and charts correctly; custom range end before start → inline error; Total Revenue KPI sums all 3 revenue types; CAC shows 'Coming in v2'; all 3 charts render with correct types and legends; Discount Code Usage table shows active and deleted codes with correct Status column; deleted code appears with 'Deleted' status; Revenue Impact shows correct negative impact; Export PDF downloads with correct filename format; exported PDF contains all KPI cards, charts, and discount table; hover tooltips show values on charts; legend click toggles data series visibility

Edge Cases
FRD7 – Future date range selected → charts show empty state, KPIs show 0 or '--'; Today filter with no transactions → KPI cards show $0/0; Export PDF server error → error toast, no file downloaded; no data in period → chart empty axes with placeholder
