ProfitPulse — The Busy-But-Broke Dashboard for Small Business Owners
Revenue is vanity, profit is sanity, and most small business owners are flying blind on the latter. ProfitPulse connects to Stripe and Wave to surface gross margin, profit per customer, and burn rate in one honest number. No accountant needed, no spreadsheet required.

Business owners consistently confuse high revenue with profitability and cannot identify which customers or periods are actually profitable without manual spreadsheet work.
What is it?
Small business owners routinely confuse revenue growth with business health, leading to the classic 'busy but broke' trap where they scale expenses in lockstep with income. ProfitPulse auto-syncs with Stripe and Wave, categorizes transactions, and surfaces three brutally honest metrics: gross profit margin, profit per customer segment, and monthly burn trajectory. The dashboard flags the exact moment revenue growth stops translating into profit — with plain-English explanations. Built on stable Plaid, Stripe, and Wave APIs, this ships as a Next.js app with Supabase in under two weeks. AppSumo lifetime deal launch plus Reddit and Twitter 'busy but broke' angle gives it a built-in hook that writes itself.
Why now?
Wave launched a public API in late 2024, and Stripe's expanded reporting endpoints now expose per-customer margin data — making this technically feasible for the first time without a custom accounting backend.
- ▸Stripe and Wave OAuth sync that auto-categorizes revenue vs. cost transactions in under 60 seconds.
- ▸Gross profit margin, profit per customer, and burn rate displayed as three big honest numbers on a single screen.
- ▸Plain-English alert when revenue grows faster than profit for two consecutive months.
- ▸Exportable one-page profit health report formatted for sharing with a bookkeeper or business partner.
Target Audience
Small business owners and solopreneurs with $5k-$100k monthly revenue, approximately 2M in the US alone, who use Stripe or Wave for billing.
Example Use Case
Maria runs a $40k/month catering business, connects Stripe in 90 seconds, and discovers her profit per customer is actually negative on weekday bookings — she raises weekend-only rates by 20% and adds $3k in monthly profit within one month.
User Stories
- ▸As a solopreneur using Stripe, I want to see my actual profit margin in one click, so that I stop mistaking revenue growth for business health.
- ▸As a small business owner, I want an alert when my burn rate outpaces profit growth, so that I can cut costs before a cash crunch hits.
- ▸As a service business owner, I want to see profit per customer segment, so that I can stop discounting the clients who cost me money.
Done When
- ✓Stripe connect: done when user clicks Connect Stripe, authorizes OAuth, and sees their transaction data load in the dashboard within 60 seconds.
- ✓Metric display: done when gross margin, profit per customer, and monthly burn appear as three large readable numbers on the main dashboard.
- ✓Burn alert: done when user receives an email alert after two consecutive months of burn growing faster than profit.
- ✓Upgrade flow: done when user hits the free tier limit, clicks Upgrade, completes Stripe checkout, and immediately gains full dashboard access.

What's the competition?
Competition Level
Medium
Similar Products
Bench for bookkeeping (requires human accountant, $299/month), Finmark for SaaS finance (too complex, too expensive), Pulse for cash flow (no profit-per-customer breakdown).
Competitive Advantage
Laser-focused on three metrics instead of a full accounting suite, deploys in 90 seconds via OAuth, and costs 10x less than hiring a bookkeeper.
Regulatory Risks
Plaid and Wave OAuth connections require OAuth security best practices. Financial data storage must comply with GDPR for EU users — implement data deletion endpoint.
What's the roadmap?
Feature Roadmap
V1 (launch): Stripe and Wave sync, three core metrics, burn alert email. V2 (month 2-3): QuickBooks integration, profit trend chart, exportable PDF report. V3 (month 4+): profit per product line, team accounts, advisor white-label.
Milestone Plan
Phase 1 (Week 1-2): Stripe OAuth, Wave OAuth, profit calc engine ships and calculates correctly on test data. Phase 2 (Week 3-4): Dashboard UI live, Stripe billing active, 10 beta users connected. Phase 3 (Month 2): 30 paying users, burn alert emails live, AppSumo deal submitted.
How do you build it?
Tech Stack
Next.js, Stripe API, Wave API, Plaid, Supabase, Recharts — build with Cursor for backend logic, v0 for dashboard components.
Suggested Frameworks
Next.js App Router, Supabase client, Recharts
Time to Ship
2 weeks
Required Skills
Stripe and Wave OAuth, Supabase Postgres, basic charting with Recharts.
Resources
Stripe API docs, Wave public API, Plaid Quickstart, Supabase docs.
MVP Scope
app/page.tsx (landing + hero), app/dashboard/page.tsx (main metrics view), app/api/connect/stripe/route.ts (Stripe OAuth), app/api/connect/wave/route.ts (Wave OAuth), app/api/metrics/route.ts (profit calculations), lib/db/schema.ts (Drizzle schema), lib/calc/profit.ts (margin and burn logic), components/MetricCard.tsx (big number card), components/BurnChart.tsx (Recharts line), seed.ts (demo data), .env.example (required env vars).
Core User Journey
Sign up -> connect Stripe via OAuth -> see gross margin, profit per customer, and burn on one screen in under 2 minutes -> upgrade to paid.
Architecture Pattern
User connects Stripe/Wave via OAuth -> tokens stored encrypted in Supabase -> cron job pulls transactions nightly -> profit calc engine runs -> metrics written to Postgres -> dashboard reads cached metrics on page load.
Data Model
User has one Profile. Profile has many ConnectedAccounts. ConnectedAccount has many Transactions. Transactions aggregate into one MonthlyMetricSnapshot per calendar month.
Integration Points
Stripe API for revenue data, Wave API for expense and invoice data, Plaid for bank transaction categorization, Supabase for database, Resend for email alerts, Vercel for hosting.
V1 Scope Boundaries
V1 excludes: QuickBooks integration, mobile app, team accounts, tax estimation, and invoice generation.
Success Definition
A stranger with zero accounting background connects their Stripe account, reads their profit margin, and says the number surprised them — then upgrades without any founder nudge.
Challenges
Wave's API access requires approval and has limited transaction data depth — must validate coverage before launch. Distribution is the real killer: most SBO-targeted finance tools die on ProductHunt because owners don't browse PH.
Avoid These Pitfalls
Do not attempt to replace accounting software — position as a profit clarity layer, not a bookkeeper. Do not launch without a working Wave API approval — apply on day one. Finding first 10 paying customers takes longer than building; budget 3x more time on distribution.
Security Requirements
Supabase Auth with Google OAuth. OAuth tokens encrypted at rest using Supabase Vault. RLS on all user tables. Rate limiting 60 req/min per IP. GDPR data deletion endpoint required.
Infrastructure Plan
Vercel for frontend and API routes. Supabase Postgres for all data. GitHub Actions for CI. Sentry for error tracking. Vercel cron for nightly sync. Total infra: ~$100/month.
Performance Targets
100 DAU and 500 req/day at launch. Dashboard load under 2s. Metric API under 400ms. CDN for static assets via Vercel Edge.

First Run Experience
On first run: a demo dashboard pre-loaded with fictional catering business data showing gross margin at 34%, profit per customer at $87, and burn at $4,200/month. User can immediately explore all three metrics and the burn trend chart. No manual config required: demo mode runs on seed data before any OAuth connection.
How to build it, step by step
1. Define Drizzle schema for User, ConnectedAccount, Transaction, and MonthlyMetricSnapshot in lib/db/schema.ts. 2. Scaffold Next.js app with Supabase Auth and Google OAuth using npx create-next-app. 3. Build Stripe OAuth connect flow in app/api/connect/stripe/route.ts. 4. Build Wave OAuth connect flow in app/api/connect/wave/route.ts. 5. Write profit calculation logic (gross margin, profit per customer, burn) in lib/calc/profit.ts. 6. Create a nightly Vercel cron job that syncs transactions and writes MonthlyMetricSnapshot. 7. Build MetricCard and BurnChart components using v0 with Recharts. 8. Wire dashboard page to read latest MonthlyMetricSnapshot from Supabase. 9. Add Resend email alert when profit margin drops month-over-month. 10. Verify: connect a real Stripe account, confirm three metrics display correctly, and upgrade flow processes payment end-to-end.
