Company Architecture Implementation - COMPLETE ✅

Date: 2026-01-05 Status: Code complete, migration ready to run Architecture: Domain-based company identity (email domain = company)

---

🎯 What Was Built

1. Database Migration ✅

File: database/migrations/002_add_company_architecture.sql

What it creates:

• companies table (domain-based identity)

• company_id column in user_profiles

• company_name column in user_profiles

• fleet_company_id column in service_requests

• supplier_company_id column in service_requests

• assigned_to_user_id column in service_requests

• assigned_at timestamp column in service_requests

• Updated status enum to include 'assigned'

• Helper functions: extract_domain(), get_or_create_company()

2. TypeScript Types ✅

File: lib/supabase.ts

Updated interfaces:

• Company (new interface)

• UserProfile (added company_id, company_name, new roles)

• ServiceRequest (added company fields, assigned status)

3. Domain Extraction Utilities ✅

File: lib/domainExtraction.ts

Functions:

• extractDomain(email) - Get domain from email

• isFreeEmailDomain(email) - Check if Gmail/Yahoo/etc

• suggestCompanyName(domain) - Auto-generate name from domain

• validateCompanyDomain(email) - Validation logic

• getOrCreateCompany() - Main company creation logic

4. Signup Flow Integration ✅

File: App.tsx

Both supplier and fleet signup now:

1. Extract domain from email

2. Create or get existing company

3. Link user to company

4. Log whether company is new or existing

🔑 Key Features

Domain-Based Identity (No Random IDs)

Email: [e-mail]
Domain: t420.io (DNS-unique, no collision)
Company: T420 Logistics

Team Visibility

T420 Fleet (@t420.io):
├── Zane (Fleet Operator)
├── Sarah (Dispatch)
└── Mike (Manager)

All see company requests
WhatsApp can't do this!

New "Assigned" Status

Status Flow:
pending → assigned → acknowledged → accepted → in_progress → completed
                ↓
             declined

🚀 How to Run Migration

Option 1: Via Script (Recommended)

node scripts/run-migration-002.js

Option 2: Supabase SQL Editor

1. Go to: https://supabase.com/dashboard/project/bsbjwjpgiangjqqqxota/sql

2. Copy contents of database/migrations/002_add_company_architecture.sql

3. Paste into SQL Editor

4. Click "Run"

Verify Migration

node scripts/check-companies-table.js

Expected output:

✅ Companies table EXISTS!
✅ user_profiles.company_id exists
✅ service_requests.assigned_to_user_id exists

---

🧪 How to Test

Test 1: First User Creates Company

# Start dev server
npm run dev

# Navigate to
http://localhost:3000/?view=FLEETOS

# Click "Get My Free Agent Number"
# Fill form:
   Company: ABC Tires
   Email: [e-mail]

# Submit and check console:
   ✨ New company created
   🌐 Domain: abctires.com
   🆔 Company ID: [uuid]

Test 2: Second User Joins Existing Company

# Navigate to same page
http://localhost:3000/?view=FLEETOS

# Click "Get My Free Agent Number"
# Fill form:
   Company: ABC Tires
   Email: [e-mail]  # SAME DOMAIN

# Submit and check console:
   🔗 Joined existing company  # NOT new!
   🆔 Company ID: [same uuid as mike]

Test 3: Verify in Supabase

# Check companies table
SELECT * FROM companies WHERE domain = 'abctires.com';

# Should show:
# - company_id
# - domain: abctires.com
# - company_name: ABC Tires
# - company_type: supplier

# Check user_profiles
SELECT name, email, company_id FROM user_profiles
WHERE company_id = [uuid from above];

# Should show BOTH users:
# - [e-mail]
# - [e-mail]

🎯 What This Enables

For Suppliers (Multi-Tech Shops):

ABC Tires (@abctires.com):
- Office sees all incoming requests
- Dispatch assigns to techs
- Techs see "assigned to me"
- Owner sees analytics

For Fleets (Dispatch Operations):

T420 Fleet (@t420.io):
- Night dispatch handles emergencies
- Day dispatch handles scheduled
- Manager reviews all activity
- CFO exports audit trail

Competitive Advantage:

WhatsApp: Individual tool (no team features) FleetOS: Company tool (built for teams)

⚠️ Migration Notes

Safe to Run:

• ✅ Uses IF NOT EXISTS for all tables

• ✅ Uses ADD COLUMN IF NOT EXISTS for columns

• ✅ Drops and recreates constraints (safe)

• ✅ Creates indexes for performance

• ✅ Includes rollback SQL (commented)

Potential Issues:

1. If companies table already exists: Migration will skip (okay)

2. If columns already exist: Migration will skip (okay)

3. Status enum update: Drops constraint, recreates with new values

Rollback:

-- Rollback SQL is included in migration file
-- Uncomment the rollback section if needed

💡 Key Decisions Made

1. Domain = Company (No Random IDs)

Decision: Use email domain as company identifier Why: DNS-unique, no collision, familiar to users

2. Free Email Providers Allowed (For Now)

Decision: Don't block Gmail/Yahoo in signup Why: MVP needs low friction, can add validation later

3. Assigned Status Added

Decision: Add new status between pending and acknowledged Why: Multi-tech shops need to assign work internally

4. Company Type (fleet/supplier/mixed)

Decision: Track what type of company it is Why: Future features may differ by type

5. Denormalize company_name

Decision: Store company_name in both tables Why: Faster queries, avoid joins

---

🎨 UI Changes Needed (Future)

SupplierTodoList:

• Filter: "Assigned to me" vs "All company"

• Show assignee name on cards

• Assignment dropdown (dispatch only)

SupplierDirectory:

• Show company name (not just individual)

• Filter by company

RequestTrackingPage:

• Show which tech is assigned

• Show company info
