AI voice agents vs. collection agencies: what the numbers look like

Traditional third-party collection agencies charge 30 to 50 percent of whatever they recover. For a $5,000 invoice that's $1,500 to $2,500 in fees — assuming they collect at all.

There's also a less visible cost: the customer relationship. When a third-party collector calls, FDCPA requires them to identify themselves as a debt collector collecting a debt — the Mini-Miranda disclosure. This frames the call as an adversarial collections action, not a business follow-up. Customers who receive that call rarely come back.

For a $5,000 invoice: doing nothing yields $0 recovered. Sending to an agency at 35% average fee yields $3,250 net, and the customer relationship is almost never retained. Using Syntharra at 10% yields $4,500 net, and the customer relationship is usually retained. In-house AR staff at $25–$40/hr may yield $4,900 — if it actually happens — but you've paid for the time regardless.

The agency model makes more sense for older, larger debts where the relationship is already lost. For invoices under $10,000 that are less than 90 days overdue, an AI voice agent calling on your behalf preserves the relationship while recovering the money. The full invoice collection software buyer's guide compares the categories side by side.

Syntharra calls are first-party: the agent says "I'm calling on behalf of [Your Business]," not on behalf of a collection agency. The call is a business courtesy call, not a collections action. TCPA applies; FDCPA does not.

The 10% success fee means Syntharra only makes money when you do. No recovery, no charge.
