Syntharra

Why Syntharra exists

Most small service businesses — HVAC, plumbing, landscaping, consulting — lose 8 to 12% of their revenue to invoices that simply age out. The problem isn’t that customers refuse to pay; it’s that nobody follows up consistently. Hiring a collector costs more than the invoice is worth. Doing it yourself burns the relationship.

Syntharra handles the follow-up with a single setup: connect your QuickBooks account once, and we call your overdue debtors compliantly, on your behalf, at no cost until we recover something. We take 10% of what we collect. Nothing else.

How we’re different

Every dollar amount, due date, and legal disclosure in a Syntharra call comes from your accounting data — not from the AI. The AI handles only the conversational flow: tone, timing, empathy. The compliance layer is deterministic. There is no prompt that can make our agent say the wrong amount or skip the TCPA disclosure. That’s not a feature we advertise; it’s a constraint we enforce at the architecture level.

Call attempts are capped at three per invoice with a minimum three-day gap between them. Every call begins with an AI identification disclosure and a recording notice. Opt-outs are instant and global — a number on our Do Not Call list is blocked across every client on the platform.
