About Ledger — AI Accounts Receivable Agent Ledger
AI agent that drafts invoice follow-ups & reads customer replies
Stop chasing invoices. Ledger is an AI agent that monitors outstanding invoices, drafts personalized follow-up emails, and reads customer replies to detect promises to pay, disputes, and excuses — automatically. Full source code, single self-contained web app (HTML/CSS/JS, no build step, no framework lock-in). BYOK architecture — your buyer's customers connect their own Claude API key, so there's zero backend to host and zero ongoing AI cost to you as the seller. Includes: a live dashboard (overdue / at-risk / expected / recovered), AI-drafted follow-ups that adjust tone based on invoice age, automatic reply classification with dispute escalation to a human queue, per-invoice activity timeline, and CSV bulk import. Built for agencies, SaaS companies, consulting firms, freelancers, and any B2B business that invoices customers. One recovered $5,000 invoice pays for this many times over. v1 ships with manual/CSV invoice entry — direct QuickBooks/Xero/Stripe sync is the obvious next build for whoever takes this on.
Next step: <p>Wire up direct sync with QuickBooks, Xero, or Stripe so invoices flow in automatically instead of manual/CSV entry</p><p>Add one-click email sending (SendGrid/Postmark) instead of copy-paste</p><p>Turn it into a hosted, multi-tenant SaaS with subscription billing — the current BYOK single-file architecture is deliberately the fastest possible starting point for that</p><p>White-label it for accounting firms or agencies to resell to their own clients</p><p>Add multi-user/team accounts and role-based access for larger AR teams</p>
