Invoice & AR Chase Agent

Monitors unpaid invoices, sends personalized nudges with payment links, escalates intelligently, flags disputes for human attention.

Setup difficulty: advanced

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

1

Connect to your accounting system

QuickBooks / Xero / Stripe Invoices / FreshBooks API. Pull all open invoices daily with: amount, days outstanding, client contact, payment link.

2

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.

3

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.

4

Always include the payment link

Single biggest lift: every reminder has a one-click payment link (Stripe, QBO Pay). Friction kills collection rates.

5

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).

6

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.

Day 7 Friendly Nudge
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}}
Day 45 Final Notice
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}}
Dispute Detection Keywords
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.

Failure modes & mitigations

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.
