CollectIQ — The AR Collections Copilot That Tells You Which Invoice to Chase First
Your AR team is staring at a 400-row aging report every Monday deciding who to call, who to email, and who to ignore. CollectIQ replaces that spreadsheet with an AI-prioritized collections queue that writes the chase emails for you.

AR Coordinators spend most of their week manually triaging aging reports and writing follow-up emails in spreadsheets, a workflow that has not changed in 20 years despite clear automation potential.
What is it?
Accounts Receivable Coordinators spend 60-70% of their week manually triaging aging reports, composing follow-up emails, and updating spreadsheets — tasks that generate zero revenue and can be fully automated. CollectIQ ingests your QuickBooks or Xero aging report via CSV or direct API, scores each overdue invoice by risk (days overdue, customer history, invoice size, dispute flags), and generates a daily prioritized call/email queue. One click sends a personalized collections email per invoice. Why 100% buildable right now: QuickBooks and Xero both have stable OAuth APIs, Claude writes frighteningly good collections emails, and the target user (AR Coordinators at SMBs) has a $50-99/month budget and a pain so acute they will pay on the first demo.
Why now?
QuickBooks Online crossed 7M subscribers in 2025 and their App Marketplace approval pipeline is faster than ever — a listed AR automation app gets organic installs from day one without paid acquisition.
- ▸AI risk-scoring of every overdue invoice using days overdue, invoice size, and customer payment history (Implementation: Claude scoring prompt + Postgres history table)
- ▸One-click personalized collections email generation and send via Resend with merge fields
- ▸Daily prioritized chase queue replacing the Monday morning aging report ritual
- ▸QuickBooks and Xero OAuth sync with CSV fallback for non-integrated users
Target Audience
AR Coordinators and finance managers at SMBs with $1M-$20M revenue, roughly 400,000 businesses in the US alone running QuickBooks or Xero.
Example Use Case
Maria, AR Coordinator at a $5M distributor, connects QuickBooks in 3 minutes, gets a prioritized list of 23 overdue invoices ranked by risk score, sends 15 personalized chase emails in 8 minutes, and recovers $47k in the first week.
User Stories
- ▸As an AR Coordinator, I want my overdue invoices ranked by collection risk automatically, so that I stop wasting time on low-priority follow-ups.
- ▸As a finance manager, I want personalized chase emails generated per invoice in one click, so that my team sends consistent professional communications without copy-pasting templates.
- ▸As a small business owner, I want to connect my QuickBooks account and see what is owed to me in under 5 minutes, so that I can act on it before the week starts.
Done When
- ✓CSV import: done when user uploads a QuickBooks aging report CSV and sees a populated invoice queue within 10 seconds.
- ✓Risk scoring: done when each invoice displays a score from 1-10 with a one-sentence reason visible on hover.
- ✓Email generation: done when user clicks Generate Email and a personalized draft appears pre-filled with customer name, invoice number, and amount within 3 seconds.
- ✓QuickBooks connect: done when user clicks Connect QuickBooks, completes OAuth, and sees their live invoices synced without any manual steps.

What's the competition?
Competition Level
Medium
Similar Products
HighRadius (enterprise, $50k+ ACV), Tesorio (mid-market, $20k+ ACV), Kolleno (closer but limited AI) — none target SMB AR Coordinators at $79/month with a self-serve setup.
Competitive Advantage
Cheaper than HighRadius ($50k+), simpler than Tesorio, and unlike generic email tools it actually reads your aging report before writing the email.
Regulatory Risks
Financial data handling requires clear data processing agreements. QuickBooks OAuth production approval requires Intuit review. GDPR compliance needed for EU customer invoice data.
What's the roadmap?
Feature Roadmap
V1 (launch): CSV import, risk scoring, email generation, QuickBooks OAuth. V2 (month 2-3): automated follow-up sequences, dispute flag detection, Xero sync. V3 (month 4+): team seats, payment portal link injection, Slack daily digest.
Milestone Plan
Phase 1 (Week 1-2): CSV import, scoring, and email generation working with demo data. Phase 2 (Week 3): QuickBooks OAuth live, Stripe billing, 5 beta users onboarded. Phase 3 (Month 2): 20 paid users, QuickBooks Marketplace application submitted.
How do you build it?
Tech Stack
Next.js 14, Claude API, Supabase, QuickBooks OAuth API, Xero API, Resend — build with Cursor for backend logic, v0 for dashboard UI
Suggested Frameworks
Drizzle ORM, QuickBooks Node SDK, LangChain for prompt chaining
Time to Ship
3 weeks
Required Skills
QuickBooks OAuth, Xero API, Claude API, Next.js, Supabase.
Resources
QuickBooks developer docs, Xero API docs, Anthropic Claude docs, Drizzle ORM quickstart.
MVP Scope
app/page.tsx (dashboard with invoice queue), app/api/sync/route.ts (QuickBooks/CSV ingest), app/api/score/route.ts (Claude risk scoring), app/api/email/route.ts (Resend email send), app/connect/page.tsx (QuickBooks OAuth flow), lib/db/schema.ts (invoices, customers, email_log tables), lib/claude.ts (scoring + email prompt), components/InvoiceQueue.tsx (prioritized list UI), seed.ts (20 demo invoices), .env.example
Core User Journey
Connect QuickBooks -> see prioritized invoice queue -> click Generate Email -> review and send -> mark invoice as chased.
Architecture Pattern
QuickBooks OAuth -> aging report fetched -> invoices stored in Postgres -> Claude scores each invoice -> priority queue rendered -> user clicks Send -> Claude writes email -> Resend delivers -> email_log updated.
Data Model
User has many Customers. Customer has many Invoices. Invoice has one RiskScore. Invoice has many EmailLogs. EmailLog records sent date, template used, and response status.
Integration Points
QuickBooks API for invoice sync, Xero API for invoice sync, Claude API for risk scoring and email generation, Resend for email delivery, Stripe for subscriptions, Supabase for data.
V1 Scope Boundaries
V1 excludes: payment portal, dispute tracking, team multi-seat, Sage and NetSuite connectors, automated follow-up sequences.
Success Definition
An AR Coordinator at a company the founder has never spoken to signs up via the QuickBooks Marketplace, connects their account, and sends their first chase email batch without any founder help.
Challenges
QuickBooks OAuth approval takes 2-4 weeks for production access — start the application on day one; the hardest non-technical problem is convincing AR Coordinators their boss approved the $79 spend, since budget authority often sits one level up.
Avoid These Pitfalls
Do not wait for QuickBooks production OAuth approval before validating with CSV uploads — ship CSV first and use it to get 5 paying customers before applying. Do not build payment portal integration in V1. Finding your first 10 paying customers will take longer than building — budget 3x more time for LinkedIn outreach than development.
Security Requirements
Supabase Auth with Google OAuth. RLS on all invoice and customer tables scoped to user. QuickBooks tokens encrypted at rest. Rate limiting 60 req/min per user. GDPR: full data deletion on account close.
Infrastructure Plan
Vercel for Next.js and API routes, Supabase for Postgres and auth, GitHub Actions for CI, Sentry for errors — estimated $115/month total at launch.
Performance Targets
50 DAU at launch, 500 req/day. Invoice queue render under 800ms. Email generation under 3s. QuickBooks sync under 10s for 500 invoices.

First Run Experience
On first run: 20 pre-seeded demo invoices appear in the queue ranked by risk score with sample customer names and amounts. User can immediately click Generate Email on any invoice and see a full draft. No manual config required: demo mode works without any API key or QuickBooks connection.
How to build it, step by step
1. Define schema: invoices, customers, risk_scores, email_logs in lib/db/schema.ts. 2. Run npx create-next-app collectiq --typescript --tailwind --app. 3. Build CSV parser endpoint in app/api/sync/route.ts accepting standard QuickBooks aging report format. 4. Build Claude risk scoring in lib/claude.ts with a structured prompt returning score 1-10 plus reasoning. 5. Build InvoiceQueue component in components/InvoiceQueue.tsx sorted by risk score descending. 6. Build email generation endpoint in app/api/email/route.ts calling Claude then Resend. 7. Add QuickBooks OAuth flow in app/connect/page.tsx using quickbooks-node SDK. 8. Add Stripe checkout for $79 Pro plan in app/api/checkout/route.ts. 9. Seed 20 realistic demo invoices in seed.ts spanning 30-120 days overdue. 10. Verify: upload demo CSV, confirm queue renders sorted by risk, click send on top invoice, confirm email arrives in test inbox end-to-end.
