This is what ET Management's team opens every morning. Admin Portal at the top. Team Communication. Closing · GST · FRS. Yi.ncome transactions. Hamburger to anywhere else. No tabs to discover, no settings to configure - just the work.

What's inside

The full picture, not a chat tool with extras.

Five work streams, one workspace. Built for accounting practices that don't want to glue Slack + Asana + Outlook + Sheets together every morning.

Tickets + AI Outbox

Every client email becomes a tracked ticket. AI drafts the reply (deadline questions, job status, doc submissions). Manager approves with a click.

  • Multipart MIME sent via Gmail
  • Source email auto-archived on close
  • Sensitive-keyword escalation pre-filter

Internal chat with a tutor

3-column WhatsApp-style chat. An AI tutor enforces one rule: a mention is never silently a task. #Task @person spawns one. #Instruction requires acks.

  • Send-time intent classification
  • BLOCK / COACH / WARN verdicts
  • Nested replies, attachments, edit-as-new

Tasks with clarification flow

Open → accepted → in-progress → done. With a clarification round-trip baked in: assignees ask, assigners answer, the whole Q&A becomes the task's discussion.

  • Re-assign with inherited context
  • AI discussion summary on demand
  • Auto-pings the assigner in chat

Closing / GST / FRS

Year-by-year client tracker, statutory calendar, FRS workpaper progress, GST cadence. Pulled from your existing Google Sheets - no double-entry.

  • Monthly & quarterly views
  • Calendar of closings + GST + statutory
  • "Manager intervene" alerts on stale cases

Yi.ncome transactions

Per-client database access, transaction drilldown, daily & monthly volume tracking - all from inside the workspace. Your bookkeeper never leaves the tab.

  • Database overview across all clients
  • Per-client transaction explorer
  • Live data, no exports
The stack

Integrates with what you already use.

Yi.Flow doesn't replace Gmail. Or Sheets. Or your books. It sits on top of them - reading, writing, learning, and giving your team a single place to coordinate.

Live Google Workspace

Gmail

Service-account access with workspace domain-wide delegation. We don't just read your inbox - we run on it.

  • Bidirectional sync - INBOX is source of truth
  • Multipart MIME send + auto-archive on close
  • Dry-run drafts mode for review-then-send
Live Google Workspace

Sheets

Your existing client database, FRS tracker, ET Check List for job status - all read by Yi.Flow with fuzzy matching and SQLite caching.

  • 488 clients live (and counting)
  • Fuzzy match on "aurora" → "Aurora Retail Pte Ltd"
  • No double-entry - your sheets stay yours
Live Yi. Suite native

Yi.ncome

Direct database access for every client your firm services. Bookkeepers query, post and reconcile without leaving Yi.Flow.

In build Google Workspace

Docs → mini-RAG

Your firm's internal procedures, client SOPs, IRAS interpretations, GST treatment notes - vectorised and queryable inline from any chat or task.

  • "How do we handle...?" answered from your own playbook
  • New staff onboard by chatting with Yi
  • Your IP stays yours - never used to train models
In build Yi. Suite native

We built this for our own firm.
