AI invoice collection for HVAC contractors
Most HVAC contractors are excellent at the job and bad at chasing invoices. Syntharra connects to your accounting software, calls every overdue customer three days after the due date, and charges 10% of what gets recovered. No monthly fee. No chasing.
HVAC service calls generate invoices that customers routinely defer. The job is done, the equipment works, and the invoice sits at the bottom of someone's inbox. By the time you follow up — if you follow up — the money is harder to recover and the conversation is more awkward than it needed to be. Syntharra eliminates both problems. The moment an invoice crosses three days past due, a compliant AI voice agent calls the customer inside the legal call window. The agent identifies as AI, discloses the recording, and asks directly about the invoice. Payment goes through Stripe Connect into your account. Disputes route to your dashboard for a human to handle. You pay 10% of what gets recovered.
How it works for HVAC contractors
Day-3 follow-up, not day-47
Recovery rates above 85% at day 3 drop to below 45% by day 47. Syntharra calls on day 3 automatically, while the conversation is still easy.
Compliant on every call
AI disclosure, recording notice, TCPA call windows, DNC checking, and dispute escalation all run at the infrastructure layer before the agent speaks. See /compliance for the full architecture.
Works with your existing accounting software
Syntharra connects to QuickBooks Online, Xero, FreshBooks, Square, Zoho Books, and Jobber. No spreadsheet exports, no manual entry.
10% success fee, nothing else
No monthly subscription. No per-call fee. If nothing is recovered, you pay nothing. The incentive structure is simple: Syntharra only makes money when you do.
Frequently asked questions
How does Syntharra work for HVAC invoice collection?
You connect your accounting software — QuickBooks, Xero, FreshBooks, Square, Zoho, or Jobber — and Syntharra monitors your aging report. When an invoice goes 3 days past due, the AI agent calls the customer inside the TCPA call window, identifies as AI, and either collects payment through Stripe Connect or logs the outcome to your dashboard.
Is AI voice invoice collection legal for HVAC businesses?
Yes, when run inside federal TCPA and applicable state laws. Syntharra enforces AI disclosure, recording notice, call-window rules, DNC checking, and dispute escalation at the infrastructure layer before the agent runs. See /compliance for the full architecture.
What happens when an HVAC customer disputes the invoice on the call?
The call ends immediately. The invoice is flagged in your dashboard and routed to your office for human review. No automated follow-up runs on a disputed invoice.
How much does Syntharra cost for HVAC contractors?
10% of the amount recovered on each invoice, charged only when recovery happens. No monthly fee, no per-call charge, no setup cost.
