Clockbill — time tracking and invoicing for freelancers
A solo-built SaaS, live in production. Track time, set per-project rates, and turn billable hours into invoices.
- Product: timer and manual entries, rounding, reports, weekly timesheets, CSV import from Toggl, Clockify and Harvest, and printable invoices.
- Pro plan: budgets and retainers, AI-learned invoice templates, and scheduled invoice emailing.
- Payments: subscriptions through Dodo Payments (Merchant of Record), with webhook-driven plan state.
- AI: Claude-powered work summaries and invoice layout extraction. The model never computes money.
- Architecture: a client-only SPA talking straight to Supabase, with all access control in Postgres Row Level Security. Optimistic writes through TanStack Query, realtime sync across devices, and Deno Edge Functions for billing and mail.
