Overview

Sumi is a CRM and booking platform for tattoo artists and studios. It brings the entire booking lifecycle into a single workspace: public intake forms, client records, project tracking, scheduling, deposits, signed deposit agreements, onboarding, admin operations, and shared inbox workflows.

Most tattoo booking workflows happen across fragmented channels: Instagram DMs, email threads, notes apps, spreadsheets, calendars, and payment links. Sumi centralizes that work so solo artists can move from inquiry to confirmed appointment with less back-and-forth.

The primary design goal is reducing operational overhead while preserving the flexibility each artist needs in their booking process. Product direction comes from direct studio workflow research, artist interviews, and design partner feedback.

Core Concepts

  • hosted and embeddable public booking forms
  • intake projects that become active, scheduled, completed, or archived work
  • client records shared across projects and inbox conversations
  • shared mailbox workflows with conversation history attached to clients and projects
  • appointment proposals based on artist availability and Google Calendar conflicts
  • signed deposit agreements with digital signatures and stored PDFs
  • manual deposit collection and verification
  • configurable email templates, form copy, and workspace settings
  • team access for artists who work with assistants or guest artists

The system is designed around incremental adoption: artists can start with intake and project tracking, then add scheduling, deposits, agreements, and inbox workflows as their process matures.

I own product discovery, customer workflow research, roadmap decisions, architecture, customer-facing UI, onboarding, payments, scheduling, analytics, and studio-facing positioning. The current release work is informed by roughly 20 artist interviews and 2 working artist workflows.
