Problem

Creative studio cobbled together Asana, Quickbooks, Notion, and Google Drive. Context-switching cost real hours; client touchpoints fell through cracks.

Users

Internal — 12-person design studio + 30 active clients

Key flow

  1. 1PM creates project, assigns team members and milestones
  2. 2Team tracks hours; client sees status + comments in portal
  3. 3On milestone, invoice is generated and sent automatically

What I built

  • Project tracker with per-client workspaces and shared timeline
  • Invoice generator pulling from tracked hours, exports as Stripe link
  • Client portal — clients see only their projects + invoices
  • Slack notifications on milestone, invoice paid, or feedback request

Limits

  • No accounting integration — Quickbooks export is manual CSV
  • File storage limited to 2GB/client — bigger files stay in Drive
