Syntharra is an AI voice payment-collection service for small and mid-sized businesses.
We connect to your accounting software, monitor invoices, and automatically call
customers when invoices go 3+ days past due. We charge 10% of the amount we recover.
There is no monthly fee and no upfront cost.

## Who it's for
Service businesses with $5k–$500k in overdue receivables: HVAC, plumbing, electrical,
dental and medical practices, law firms, agencies, contractors, and B2B SaaS. Owner-
operators and one-person AR teams who don't want to make the calls themselves.

## What it costs
- 10% of recovered amount, billed only on collection
- $0 monthly fee, $0 setup fee, $0 per-call fee
- Stripe Connect routes paid invoices directly to the customer's bank — Syntharra never holds funds

## How it works
1. Connect QuickBooks, Xero, FreshBooks, Square, Zoho Books, or Jobber via OAuth (3 minutes)
2. Connect Stripe Connect for payment routing (2 minutes)
3. Syntharra polls invoices and queues calls when an invoice is 3+ days past due
4. AI voice agent (Retell) calls during compliant local hours (9am–8pm, no weekends)
5. Calls open with mandatory TCPA disclosures: "this call may be recorded" + "I'm an AI assistant"
6. Debtor pays via SMS link or IVR; Stripe routes funds directly to client bank
7. Syntharra invoices 10% only on collected amounts

## Compliance posture
- Deterministic compliance layer for TCPA, FDCPA, and state call-window rules
- All dollar amounts, dates, and legal disclosures are injected from the database — never LLM-generated
- DNC opt-outs are honored instantly and globally across all clients
- Max 3 attempts per invoice; min 3 days between attempts
- Human escalation after 3 attempts

## Brand canonical
"Connect QuickBooks. We handle the rest. 10% of recovered amount. No monthly charge.
Compliance-first AI voice collections for small businesses."
