Retainer Hours Client Report
Upload your time-tracking export and get a clean monthly retainer report for each client: hours used, hours left, rollover and what the time was spent on.
Economics
- Pricing example
- $12/month (up to 15 clients)
- Daily math
- 50 subscribers x $12/month = $600/month, about $20/day.
- Target if you hit the daily math
- Target: $600 / month at 50 subscribers
Audience and urgency
Audience: Small agencies, freelance developers, marketers and virtual assistants who work on monthly hour retainers.
Urgency: Retainer clients want to see where their hours went. Building that report from a time-tracker export each month takes hours of spreadsheet work, and unclear reports lead to disputes and lost renewals.
MVP scope
- ✓ CSV import from any time tracker with a column-mapping step (date, client, project, task, hours, notes)
- ✓ Retainer settings per client: monthly hours, rollover rule, overage rate
- ✓ Monthly report: hours used vs included, rollover balance, overage amount, breakdown by project/task
- ✓ Branded PDF and a share link per client
- ✓ Stripe subscription; data kept per month and deletable
Omitted features
- - Do NOT build a time tracker
- - Do NOT build invoicing or payment collection
- - Do NOT add time-tracker API integrations in Day 1 (CSV import only)

Build a "Retainer Report" web app in React with Tailwind CSS and Supabase. Core requirements: 1. Clients with retainer settings: monthly included hours, rollover rule (none / roll over up to N hours / roll over all), overage hourly rate, currency, logo for the report. 2. Monthly CSV import with column mapping (date, client, project, task, hours or duration, notes); saved mappings per time tracker; client name matching with a manual fix step. 3. Report calculation: hours used, included, rollover in/out, remaining, overage hours and amount; breakdown by project and task with a simple bar chart. 4. Outputs: branded PDF and a share link /r/[random-id] (noindex) per client per month. 5. Magic-link auth, Stripe Billing ($12/month up to 15 clients), and delete-month/delete-client buttons.
