## Pre-Billing (Month-End)

- [ ] Query Notion Tasks Dashboard for all tasks with `Billable` = checked for the billing month
- [ ] Verify `Client Code` is set on all billable tasks
- [ ] Verify `Effort (hrs)` is filled in for all billable tasks
- [ ] Flag any tasks missing billing fields -- notify Andrew

## Per-Client Invoice Generation

For each client with billable tasks:

- [ ] Aggregate hours by service module (A1-A6, T1-T7, G1-G4)
- [ ] Apply correct rate per module (reference: `06_PRICING-PACKAGES.md`)
- [ ] Calculate subtotals per line item
- [ ] Calculate 부가가치세(VAT) at 10%
- [ ] Calculate total (공급가액 + VAT)
- [ ] Generate invoice draft using `D.intelligence_Invoice_2026` template
- [ ] Mark draft with `[DRAFT - Awaiting Review]`
- [ ] Submit to Andrew for review

## Post-Approval

- [ ] Andrew approves invoice
- [ ] Send invoice to client
- [ ] Record in Google Sheets billing tracker
- [ ] Set payment due date (typically 30 days)
- [ ] Update Notion tasks: mark as billed

## Payment Tracking

- [ ] Monitor payment receipt by due date
- [ ] If overdue: flag for Andrew (do NOT contact client directly)

- [ ] Reconcile: match payment to invoice

## Monthly Close
