Your Customers Stop Reading. They Still Answer Their Phone.
Email open rates on collection reminders drop to single digits by the third follow-up. A phone call changes the dynamic entirely - but your team can't make 200 calls a week.
The Pain
- ✗Email open rates on payment reminders drop below 10% by the 3rd follow-up
- ✗Customers deprioritize invoices with no human accountability
- ✗No way to capture excuses, disputes, or promises in real time
The Fix
- ✓AI calls mention the exact invoice number, amount, and due date
- ✓Customers engage when they hear a voice - even an AI one
- ✓Promises-to-pay and dispute flags are captured automatically
The Pain
- ✗Finance team can handle 15-30 calls per person per day at most
- ✗High-value invoices get attention; small ones sit unpaid for months
- ✗Staff burnout and inconsistency - tone varies call to call
The Fix
- ✓AI agents make hundreds of calls in parallel, any time of day
- ✓Every invoice - $500 or $50,000 - gets the same diligent follow-up
- ✓Consistent, calm, professional tone on every single call
The Pain
- ✗Offshore collectors lack invoice details and lose customer trust instantly
- ✗Customers hang up when the caller can't confirm what the invoice was for
- ✗Disputes get missed because the caller has no history to reference
The Fix
- ✓AI is briefed with invoice line items, prior payments, and account history
- ✓Can reference the specific project, service, or PO the invoice covers
- ✓Detects partial payments and discrepancies before the call is made
The Pain
- ✗No scoring system - all overdue accounts treated the same
- ✗Time wasted on chronic non-payers while high-probability accounts age
- ✗Collections calendar set by invoice date, not by likelihood of recovery
The Fix
- ✓Propensity-to-Pay (P2P) model scores each account before calling
- ✓High-score accounts called first to maximize cash recovery rate
- ✓Chronic non-payers flagged for escalation rather than repeated calls
Invoice Goes Past Due. The AI Handles the Rest.
Every step is automated. Every outcome is logged. Your team sees results, not tasks.
Overdue Trigger
Your AR system (QuickBooks, Xero, or any accounting tool) flags an invoice past its due date. Our system pulls the full account context: invoice details, payment history, prior communications, and any open disputes.
Connected to your existing stack. No migration.
P2P Scoring and Call Prioritization
A Propensity-to-Pay model scores each overdue account based on payment history, days overdue, account size, and behavioral patterns. High-probability accounts are called first. Chronic non-payers are routed to escalation.
Right effort on the right accounts.
Context-Aware AI Voice Call
An AI voice agent places the call at the optimal time. It opens with the customer's name, references the exact invoice, and handles the conversation in natural language - acknowledging partial payments, navigating objections, and offering payment plan options within your approved parameters.
Sounds human. Operates at machine scale.
Outcome Captured and Logged
Every call ends with a structured outcome: promise-to-pay with a date, dispute flagged for review, payment plan agreed, or escalation to your team. Call transcripts and outcome data are written back to your CRM and accounting tool automatically.
No data entry. Full audit trail.

Not Just a Robocall. A Real Conversation.
Generic automated calls fail because customers see through them instantly. This system is built differently.
Full Invoice Context on Every Call
The AI knows the invoice number, amount, due date, line items, and what the service or project was for. Customers can't brush it off with 'I don't know what this is for.'
Natural Multi-Turn Dialogue
The AI listens and responds in real time. It handles 'can I pay half now?', 'I thought we disputed this', and 'I'll pay on Friday' - adapting mid-call without a script.
Propensity-to-Pay (P2P) Scoring
Accounts are ranked by likelihood to pay before any call is placed. High-value, high-probability accounts get called first. Bad debt risks are flagged before you waste time.
Payment Plan Negotiation
When a customer can't pay in full, the AI can offer installment plans within your approved parameters, capture the agreed schedule, and log it for automatic follow-up.
Smart Escalation
Disputes, legal threats, and emotional conversations are detected and immediately escalated to your team. The AI never argues - it de-escalates and hands off cleanly.
Compliant by Design
Call timing, frequency, and do-not-call list checking are built into every workflow. Every call log is retained for audit. Built for B2B - not consumer debt.
Optimal Call Timing
The system learns which times of day each customer is most likely to answer and adjusts scheduling accordingly. No more calling at 9am and hitting voicemail every time.
Human-Sounding Voice
Built on production-grade voice synthesis that passes for human in blind tests. Tone shifts from warm and professional to politely firm as the overdue period lengthens.
Automatic CRM and AR Sync
Call outcomes, promise dates, dispute flags, and payment plans are written back to your CRM and accounting tool in real time. Zero data entry for your team.
Built for B2B Teams That Invoice Clients
This is not consumer debt collection. It's designed for service businesses where the customer relationship matters.
Marketing and Creative Agencies
40-65 days DSOClients delay payment while demanding the next deliverable. AI calls create accountability without damaging the relationship.
IT and Software Consulting
45-70 days DSOMilestone billing creates invoice gaps. AI tracks each milestone invoice independently and follows up on the right one.
Management Consulting
50-80 days DSOSix-figure invoices sit in enterprise approval queues for months. AI calls accelerate the internal approval process.
Staffing and Recruitment
45-75 days DSOPayroll is weekly. Receivables lag 45-75 days. AI calls close that gap before cash flow becomes a crisis.
Legal and Professional Services
52+ days DSOBillable hours tracked carefully, collected poorly. AI handles the awkward payment conversation so you don't have to.
Accounting and CPA Firms
35-55 days DSOSeasonal revenue spikes mean collections pile up. AI scales calling capacity instantly without adding staff.
