ReceiptFlow — White-Label AI Receipt Processor for Accounting Firms
Accountants still manually key receipts in 2026 like it's a punishment from the universe. ReceiptFlow gives them a white-label portal to drag-drop receipts, extract structured data with Claude, and push clean line items to QuickBooks or Xero in one click. $0.001 per receipt, $299/month per firm — the math is embarrassingly good.

A developer built a 15-node n8n receipt-processing workflow for Swiss accounting firms using Claude Haiku at ~$0.001 per receipt, proving the cost structure is viable and accountants need automated alternatives to manual entry or expensive OCR tools.
What is it?
Small accounting firms process hundreds to thousands of receipts monthly for SMB clients, and the workflow is still email attachments plus manual entry. ReceiptFlow is a white-label web portal where accountants upload receipts in bulk, Claude Haiku extracts vendor, date, amount, category, and tax fields, and the structured output syncs directly to QuickBooks Online or Xero via their official APIs. Accountants brand it as their own tool, charge clients a processing fee, and pocket the margin. The n8n community proved this workflow costs ~$0.001/receipt at Claude Haiku pricing, meaning even a 500-receipt/month firm costs $0.50 in AI fees vs. $200+ in staff time.
Why now?
Claude Haiku 3.5 dropped vision costs to sub-$0.001 per receipt in early 2026, making AI receipt extraction economically trivial for the first time. QuickBooks Online API is stable and widely adopted.
- ▸Bulk receipt upload via drag-drop with PDF, JPG, PNG support and Claude Haiku field extraction.
- ▸One-click sync to QuickBooks Online or Xero with OAuth connection and category mapping.
- ▸White-label portal with custom subdomain and logo for reselling to clients.
- ▸Per-firm usage dashboard showing receipts processed, accuracy rate, and sync status.
Target Audience
Independent accounting firms and bookkeeping practices with 1-10 staff, ~50,000 firms in US/UK/AU processing SMB receipts.
Example Use Case
Sarah runs a 3-person bookkeeping firm, uploads 800 client receipts per month, ReceiptFlow extracts all fields and pushes to Xero in 4 minutes instead of 6 hours, saving her $1,200/month in labor costs.
User Stories
- ▸As a bookkeeper, I want to bulk upload client receipts and get structured data, so that I eliminate 6 hours of weekly manual entry.
- ▸As an accounting firm owner, I want a white-label portal, so that I can resell this to clients as my own product.
- ▸As a bookkeeper, I want one-click Xero sync, so that extracted receipts appear in the GL without any copy-pasting.
Done When
- ✓Upload: done when a JPG or PDF receipt is uploaded and extracted fields appear in the review table within 10 seconds.
- ✓Extraction accuracy: done when vendor, date, and amount fields are correctly populated on 90%+ of clear receipt photos.
- ✓Sync: done when clicking Push to QuickBooks creates a matching expense entry visible in the QBO sandbox account.
- ✓Billing: done when Stripe trial expires and firm is prompted to enter card details before processing more receipts.

What's the competition?
Competition Level
Medium
Similar Products
Dext (Receipt Bank) charges $50+/month per firm but has no white-label. Expensify is employee-facing not accountant-facing. AutoEntry lacks developer-friendly API — ReceiptFlow fills the white-label + API-first gap.
Competitive Advantage
White-label reselling angle differentiates from Expensify and Dext — accountants become resellers, not just users, creating lock-in and a margin incentive.
Regulatory Risks
GDPR compliance required for EU accounting clients — implement data deletion endpoint. No financial advice rendered so no licensing required.
What's the roadmap?
Feature Roadmap
V1 (launch): bulk upload, Claude extraction, QBO/Xero sync, white-label subdomain. V2 (month 2-3): multi-client sub-accounts, custom category mapping, CSV export. V3 (month 4+): QuickBooks Marketplace listing, bank statement parsing, team roles.
Milestone Plan
Phase 1 (Week 1-2): upload + extraction working end-to-end with manual review UI. Phase 2 (Week 3-4): QBO OAuth sync live, Stripe billing active. Phase 3 (Month 2): 5 paying firms, white-label subdomain feature shipped.
How do you build it?
Tech Stack
Next.js, Claude Haiku API, QuickBooks Online API, Xero API, Supabase, Stripe, Resend — build with Cursor for backend API routes, v0 for upload UI components.
Suggested Frameworks
Next.js App Router, Supabase Auth, pdf-parse for PDF extraction
Time to Ship
2 weeks
Required Skills
Claude API integration, QuickBooks/Xero OAuth, file upload handling, Stripe billing.
Resources
Anthropic Claude Haiku docs, QuickBooks Online API docs, Xero Developer docs, Supabase quickstart.
MVP Scope
app/page.tsx (landing + hero), app/dashboard/page.tsx (firm dashboard), app/api/upload/route.ts (file ingest + Claude extraction), app/api/sync/route.ts (QuickBooks/Xero push), app/api/firms/route.ts (firm CRUD), lib/claude.ts (receipt extraction prompt), lib/qbo.ts (QuickBooks OAuth helper), lib/xero.ts (Xero OAuth helper), lib/db/schema.ts (firms, receipts, sync_logs tables), components/UploadZone.tsx (drag-drop UI), components/ReceiptTable.tsx (extracted data review), .env.example (all required keys).
Core User Journey
Sign up -> connect QuickBooks or Xero -> upload receipts -> review extracted fields -> push to accounting software in one click.
Architecture Pattern
File upload -> Supabase Storage -> Claude Haiku API extracts fields -> structured JSON stored in Postgres -> accountant reviews -> QuickBooks/Xero API push -> sync log updated.
Data Model
Firm has many Users. Firm has many Receipts. Receipt has one ExtractionResult. Receipt has one SyncLog. Firm has one IntegrationConfig (QBO or Xero OAuth tokens).
Integration Points
Claude Haiku API for receipt extraction, QuickBooks Online API for GL sync, Xero API for GL sync, Supabase for database and file storage, Stripe for billing, Resend for onboarding emails.
V1 Scope Boundaries
V1 excludes: mobile app, multi-client sub-accounts, bank statement parsing, custom extraction fields, team roles beyond owner.
Success Definition
A paying accounting firm onboards without founder help, processes 200+ receipts, syncs to their accounting software, and renews after month one.
Challenges
QuickBooks and Xero OAuth approval can take 2-4 weeks — apply for API access on day one before writing any code. Distribution is harder than the build: cold outreach to accountants requires trusted referrals or LinkedIn ads targeting CPA job titles.
Avoid These Pitfalls
Do not build white-label custom domains before you have 5 paying firms — start with subdomains. Do not skip manual review step or accountants won't trust AI extraction accuracy. Apply for QuickBooks Marketplace API access week one — it takes weeks to approve.
Security Requirements
Supabase Auth with Google OAuth, RLS on all firm-scoped tables, OAuth tokens encrypted at rest, rate limit 50 uploads/min per firm, GDPR deletion endpoint required.
Infrastructure Plan
Vercel for Next.js hosting, Supabase for Postgres and file storage, GitHub Actions for CI, Sentry for error tracking, three environments: local dev, Vercel preview, Vercel prod.
Performance Targets
50 DAU at launch, 500 req/day. Claude extraction under 8 seconds per receipt. Page load under 2s. No real-time features needed in V1.
Go-Live Checklist
- ☐Security audit complete.
- ☐Payment flow tested end-to-end.
- ☐Sentry error tracking live.
- ☐QBO and Xero sandbox sync verified.
- ☐Custom subdomain SSL configured.
- ☐Privacy policy and terms published.

First Run Experience
On first run: dashboard shows 3 pre-loaded demo receipts already extracted with vendor, date, and amount fields visible. User can immediately review extracted data and click a disabled Push to Xero button (enabled after OAuth). No manual config required: demo data seeded, extraction already run, UI fully interactive.
How to build it, step by step
1. Define Supabase schema: firms, receipts, extraction_results, sync_logs tables with RLS. 2. Run npx create-next-app receiptflow and install Supabase, Stripe, Resend, pdf-parse. 3. Build /api/upload route that saves file to Supabase Storage and triggers Claude Haiku extraction. 4. Write Claude Haiku prompt that returns JSON with vendor, date, amount, category, tax fields. 5. Build ReceiptTable component in v0 showing extracted fields with inline edit capability. 6. Implement QuickBooks Online OAuth flow using qbo-node library and store tokens encrypted in Supabase. 7. Build /api/sync route that maps extracted fields to QBO journal entry schema and posts via API. 8. Add Stripe billing with 14-day trial using Stripe Checkout and webhook to activate firm account. 9. Build firm dashboard showing receipts processed, sync status, and usage stats with Recharts. 10. Verify: upload a JPG receipt, confirm extraction JSON, click sync, confirm entry appears in sandbox QuickBooks account.
