Invoice & AR Chase Agent
Monitors unpaid invoices, sends personalized nudges with payment links, escalates intelligently, flags disputes for human attention.
The Problem
Service businesses lose 5-15% of revenue to slow-pay and write-offs — not because clients won't pay, but because nobody is consistently chasing. An AR agent watches your accounting platform daily, fires personalized reminders at smart intervals, escalates with real urgency at day 60, and routes any reply that smells like a dispute to a human. Pure margin recovery with near-zero ongoing labor.

Workflow Steps
Connect to your accounting system
QuickBooks / Xero / Stripe Invoices / FreshBooks API. Pull all open invoices daily with: amount, days outstanding, client contact, payment link.
Define the chase cadence
Day 0 (due date): courteous reminder. Day 7: friendly nudge with payment link prominently. Day 21: more direct, mention overdue. Day 45: final notice before escalation. Day 60: human takes over.
Personalize the message tone
Long-term clients get warmer language. New clients get more formal language. High-value invoices get a phone call task added. The agent picks tone based on client history.
Always include the payment link
Single biggest lift: every reminder has a one-click payment link (Stripe, QBO Pay). Friction kills collection rates.
Reply classification
When the client replies, classify: PAYING_SOON (no further nudges for 7 days), DISPUTE (escalate to human immediately), QUESTION (auto-draft answer from invoice data, route to human review).
Escalation at day 45-60
Final notice triggers a Slack alert to the account owner with full thread + payment history. Human decides: phone call, payment plan offer, collections handoff.
Copy-Paste Templates
Use these templates as-is or customize for your business.
Hi {{first_name}}, just a friendly heads-up — invoice {{invoice_number}} for {{amount}} was due on {{due_date}}. If it's already in motion, ignore this message. If not, here's the one-click pay link: {{payment_link}}
Questions or anything I can help with on this? Just reply.
— {{sender}} from {{company}}Hi {{first_name}}, this is the final automated reminder on invoice {{invoice_number}} ({{amount}}, originally due {{due_date}} — now {{days_overdue}} days past).
If there's a dispute or you need to discuss a payment plan, please reply by {{response_deadline}} so we can resolve it. Otherwise this account will be passed to {{account_owner}} for direct follow-up.
Pay now: {{payment_link}}
Thanks,
{{sender}}Auto-escalate any reply containing: 'dispute', 'refund', 'wrong amount', 'didn't agree', 'charge back', 'lawyer', 'cancel'. Also escalate any reply with negative sentiment score < -0.4.
Orchestration pattern
Single agent with function-calling: one LLM with a defined toolbox (CRM, calendar, knowledge base) decides which tool to invoke at each turn. Easiest to debug; appropriate for most well-scoped SMB workflows.

Where this workflow tends to break in production — and what to put in place before you ship it.
Sends reminder after payment already received
Mitigation: Re-poll accounting system within 60 sec of send-time to confirm still unpaid.
Tone too aggressive damages relationship
Mitigation: Hard cap on assertive language until day 45+; human review on top-decile accounts.
When NOT to Use This
Skip if your client base is 1-5 large recurring clients — relationship-driven manual collection works better. Always have a human review the cadence for your highest-value accounts before automating.
