The canonical third-party evidence layer

The technical embodiment of arbitration.

Every dispute — a chargeback, a one-star review, a BBB complaint, a small-claims filing — comes down to two sides arguing over what happened, with no neutral evidence. Authyr is the neutral evidence. When a real customer pays, you get a cryptographically signed, tamper-evident receipt of the visit — verifiable by anyone, forever.

A portable, verifiable receipt

The problem

Every business pays a fear tax — because it can't prove what happened.

Liability premiums, chargeback losses, lawyer retainers, the jobs you discount just to make a threat go away — $26K to $250K+ a year depending on your industry, every line priced off evidence scarcity. Authyr's receipts attack every line. The subscription pays for itself the first time it prevents one dispute.

What you get

Reviews only real customers can write

No fakes, no bots, no competitors, no AI. Every review is tied to a payment-verified visit — and you can never quietly bury a bad one.

A 30-day window to make it right

A low review opens a private resolution window before anything is final. Fix it, and your permanent record shows you did.

Court-ready evidence packets

A print-ready document for chargebacks, BBB responses, insurance claims, and filings — verifiable by the receiving party without taking your word.

Verified customer stories

Long-form, provably human content that outranks the agency rewrites your competitors pay $3–8K/month for.

01 · Connect

Your payments, verified.

When a customer pays, Authyr issues a signed receipt of the visit automatically. Nothing for you to do.

02 · Request

Ask for the review.

One link — text or email. Only that verified customer can leave it. Low ratings open the 30-day window.

03 · Prove

Win the dispute.

Hand a bank, board, or court a signed evidence packet they can verify by math — not by your word.
