TradeMyShift — The Peer Shift Swap Marketplace for Hourly Workers Who Are Done Begging in Group Chats
Every restaurant, retail chain, and hotel has the same broken shift-swap process: someone posts in a 47-person group chat, gets ignored, and calls in sick anyway. TradeMyShift is a dead-simple web app where hourly workers post open shifts, browse available swaps, and get manager approval — all without a group chat or a phone call.

What is it?
Shift swap chaos costs the US restaurant and retail industry billions in last-minute no-shows and overtime costs annually. Workers post in WhatsApp groups, get buried, panic, and either guilt-trip a coworker or just bail. TradeMyShift gives each location a private shift board where workers post, claim, and request manager approval for swaps — with SMS notifications so no one has to check an app. Managers get a single approval queue instead of 15 text messages. This is deliberately simpler than 7shifts or Deputy: no scheduling features, no payroll, just the swap marketplace. Buildable in 2 weeks with Next.js, Supabase, and Twilio SMS. The hospitality and retail labor market employs 30+ million hourly workers in the US alone.
Why now?
Post-pandemic hourly worker turnover hit record highs in 2025-2026, making shift flexibility the top retention lever for independent restaurants — and Twilio SMS pricing dropped enough to make per-SMS costs negligible at small scale.
- ▸Shift post board where workers list shifts they need covered with date, time, and role required
- ▸One-tap claim flow where an available coworker claims a shift and triggers a manager approval SMS
- ▸Manager approval queue showing pending swaps with approve/deny in a single tap — no app download required via SMS link
- ▸Automatic SMS confirmation to both parties once a swap is approved
Target Audience
Independent restaurant owners and retail store managers with 10-50 hourly staff — roughly 500k locations in the US that can not afford 7shifts or Deputy enterprise pricing.
Example Use Case
Carlos manages a 25-person restaurant crew and used to spend 2 hours every Friday sorting out weekend swap requests over text. With TradeMyShift he checks one approval queue on Saturday morning, approves 3 swaps in 4 minutes, and goes back to prep.
User Stories
- ▸As a restaurant manager, I want one approval queue for all shift swap requests, so that I stop managing 20 individual text messages every weekend.
- ▸As an hourly worker, I want to post an open shift and get notified when a coworker claims it, so that I do not have to chase people in the group chat.
- ▸As a location owner, I want to pay a flat monthly fee per location, so that I can budget my labor management tools without per-user pricing surprises.
Done When
- ✓Shift post: done when a worker submits an open shift and it appears on the board within 5 seconds without page refresh.
- ✓Claim and SMS: done when a coworker clicks Claim and the manager receives an SMS with an approve link within 60 seconds.
- ✓Approval flow: done when manager clicks the SMS approve link and both workers receive a confirmation SMS within 60 seconds.
- ✓Stripe billing: done when manager upgrades, Stripe checkout completes, and the location roster limit is immediately removed.
Is it worth building?
$29/month per location × 100 locations = $2,900 MRR at month 4. $29/month × 500 locations = $14,500 MRR at month 10. Assumes cold outreach to independent restaurant owners at 4% conversion.
Unit Economics
CAC: $40 via in-person cold visits (1 hour per visit, 1 in 5 converts). LTV: $348 (12 months at $29/month). Payback: 2 months. Gross margin: 82%.
Business Model
SaaS subscription per location
Monetization Path
Free for up to 10 staff. $29/month per location for unlimited staff. Upgrade triggered when location exceeds 10-person roster.
Revenue Timeline
First dollar: week 3 via first paid location. $1k MRR: month 4. $5k MRR: month 10.
Estimated Monthly Cost
Twilio SMS: $30, Vercel: $20, Supabase: $25, Stripe fees: $20. Total: ~$95/month at launch.
Profit Potential
Profitable at $3k MRR. Full-time viable at $10k MRR across 350 locations.
Scalability
Can expand to multi-location chains, payroll system integrations, and a shift-fill marketplace connecting workers across nearby locations.
Success Metrics
Week 2: 3 pilot locations live. Month 2: 20 locations. Month 4: 50% of trialing locations convert to paid.
Launch & Validation Plan
Walk into 10 local restaurants and ask managers how they currently handle shift swaps. Offer 3 free months to the first 3 who say the group chat is a nightmare.
Customer Acquisition Strategy
First customer: physically visit 20 independent restaurants within driving distance, demo the product on a phone in 90 seconds, offer 90 days free. Ongoing: restaurant owner Facebook groups, local chamber of commerce, Toast and Square POS integration marketplaces.
What's the competition?
Competition Level
High
Similar Products
7shifts has scheduling, payroll, and compliance but costs $30-100/location/month with complexity SMBs hate. Deputy is enterprise-focused. ShiftBoard requires IT setup — none offer a pure SMS-native swap marketplace under $30/month.
Competitive Advantage
No app download required for workers (SMS-only flow), no scheduling complexity, half the price of 7shifts at the feature set that actually matters for small locations.
Regulatory Risks
Low regulatory risk. GDPR applies to EU locations if expanded internationally. No labor law advice is given — purely a coordination tool.
What's the roadmap?
Feature Roadmap
V1 (launch): shift board, SMS claim and approval, Stripe billing per location. V2 (month 2-3): worker self-registration via invite link, shift history log. V3 (month 4+): multi-location manager view, POS system integrations.
Milestone Plan
Phase 1 (Week 1-2): core shift board and SMS approval loop ships, done when one real swap completes via SMS. Phase 2 (Week 3-4): Stripe billing live, done when first paid location upgrades. Phase 3 (Month 2): 20 locations onboarded, done when 10 are paying.
How do you build it?
Tech Stack
Next.js, Supabase, Twilio SMS, Stripe, Resend — build with Lovable for UI, Cursor for API routes, v0 for shift card components
Suggested Frameworks
-
Time to Ship
2 weeks
Required Skills
Next.js, Supabase Auth, Twilio SMS API, Stripe billing.
Resources
Twilio SMS quickstart, Supabase RLS docs, Next.js App Router tutorial, Stripe recurring billing guide.
MVP Scope
app/page.tsx (landing + location signup), app/[locationId]/board/page.tsx (shift swap board), app/[locationId]/manager/page.tsx (approval queue), app/api/shifts/route.ts (CRUD for shifts), app/api/approve/route.ts (approval + Twilio SMS trigger), lib/db/schema.ts (locations, workers, shifts, swaps tables), lib/twilio.ts (SMS helper), .env.example (Twilio, Supabase, Stripe keys)
Core User Journey
Manager creates location -> invites workers via SMS link -> worker posts open shift -> coworker claims it -> manager approves via SMS -> both workers get confirmation.
Architecture Pattern
Worker posts shift -> Supabase insert -> coworker claims -> Supabase update -> Twilio SMS to manager -> manager clicks SMS link -> approval route -> Twilio SMS to both workers.
Data Model
Location has many Workers. Worker has many Shifts. Shift has one SwapRequest. SwapRequest has status (pending, approved, denied) and belongs to one claiming Worker.
Integration Points
Twilio for SMS notifications and approval links, Stripe for location subscriptions, Supabase for database and auth, Vercel for hosting, Resend for manager onboarding emails.
V1 Scope Boundaries
V1 excludes: scheduling, payroll integration, multi-location chains, native mobile app, shift templates, compliance reporting.
Success Definition
A restaurant owner finds TradeMyShift without founder involvement, onboards their crew, completes a real shift swap without a group chat, and pays month 2 without a nudge.
Challenges
The hardest problem is not the tech — it is convincing a restaurant owner to pay $29/month for something they currently solve (badly) with WhatsApp for free. Distribution requires in-person or phone outreach, not SEO.
Avoid These Pitfalls
Do not build a scheduling feature — it triples complexity and competes with 7shifts directly. Do not rely on App Store distribution — SMS-only for workers is the distribution moat. Finding 10 paying locations will take more cold visits than you expect — budget 3x the time.
Security Requirements
Supabase Auth magic link for managers, RLS ensuring workers only see their location's shifts, rate limiting 50 req/min per IP, SMS approval tokens expire after 24 hours, no PII stored beyond name and phone number.
Infrastructure Plan
Vercel for Next.js, Supabase for Postgres and auth, Twilio for SMS, GitHub Actions for CI, Sentry for errors — total infra under $100/month at launch.
Performance Targets
50 DAU and 500 req/day at launch, API routes under 300ms, shift board loads under 1.5s, no caching needed at this scale.

First Run Experience
On first run: a demo location called Sunrise Cafe is pre-seeded with 5 workers and 3 open shifts visible on the board. User can immediately claim a shift and see the manager approval flow using a demo phone number — no Twilio key required in demo mode. No manual config required: demo mode uses mock SMS logging to console until real Twilio keys are added.
How to build it, step by step
1. Define Drizzle schema: locations, workers, shifts, swap_requests in lib/db/schema.ts. 2. Scaffold Next.js app and install twilio, drizzle-orm, stripe, resend dependencies. 3. Build location signup flow with Supabase Auth magic link for managers. 4. Build shift board page at /[locationId]/board showing open shifts as cards using v0 components. 5. Build claim API route that creates a swap_request and fires Twilio SMS to manager with approve link. 6. Build /api/approve route that validates token, updates swap status, and sends confirmation SMS to both workers. 7. Build manager approval queue page at /[locationId]/manager listing pending swaps. 8. Add Stripe checkout for $29/month plan with webhook that unlocks locations over 10 workers. 9. Seed one demo location with 5 workers and 3 open shifts for instant demo mode. 10. Verify: create location, add 2 workers, post a shift, claim it, approve via SMS link, confirm both workers receive confirmation SMS.
