Why Invoance

Make every record provable

Invoance adds cryptographic proof to the records your business already creates. Documents, events, AI outputs, entire workflows — anchored, signed, and independently verifiable. One API call. Nothing to replace.

Four products, one platform

Event Ledger

Anchor any business event — payments, approvals, system actions — into an immutable, append-only record.

Document Anchoring

Prove any document existed in its exact form at a specific point in time. Contracts, invoices, reports — fingerprinted and signed.

AI Attestation

Record what your AI received, what it produced, and when. Verifiable proof for audits, disputes, and regulators.

Traces

Group related events into sealed proof bundles. One trace covers an entire business process with a composite cryptographic proof.

How it works

Invoance runs alongside your existing systems. No migration, no replacement. Records flow through your normal workflow — Invoance adds the proof layer.

01
Event occurs

A record is created, approved, sent, or finalized in your system.

02
Content hashed

SHA-256 fingerprint of the payload. Identical inputs always produce identical hashes.

03
Signed & anchored

Ed25519 digital signature binds the hash to your organization and a precise timestamp.

04
Independently verifiable

Anyone can verify the proof — no account, no authentication, no trust in Invoance required.

What changes when records are provable

Disputes resolve faster

When a customer, vendor, or regulator questions a record, you show cryptographic proof instead of explanations. Verification takes seconds, not weeks.

Audits become deterministic

Stop preparing for audits. Every record already carries its own proof. Auditors verify independently — no data room, no back-and-forth.

Compliance is built in

SOX Section 404 requires 7-year retention. HIPAA requires audit trails. EU AI Act requires model output records. Invoance handles all of it structurally.

Trust extends beyond your walls

Verification links are public. Partners, customers, and regulators verify records without needing access to your systems.

Before and after

Without Invoance
  • Disputes rely on internal logs and explanations
  • Audits require weeks of manual preparation
  • AI outputs have no verifiable record
  • Proof exists only as long as the system owner is trusted
  • Screenshots and emails are your best evidence
With Invoance
  • Every event carries cryptographic proof of what happened and when
  • Auditors verify records independently in seconds
  • AI inputs and outputs are hashed, signed, and timestamped
  • Proof exists independently of vendors, employees, or platforms
  • Public verification links replace trust assumptions

What's under the hood

SHA-256 hashing

Every payload is fingerprinted. Identical content always produces the same hash.

Ed25519 signing

Asymmetric signatures bind records to your organization. Non-repudiable by design.

Precise timestamps

Cryptographically bound to the proof entry. Cannot be backdated or altered.

Append-only ledger

No edits. No deletions. Any modification attempt is immediately detectable.

Public verification

Anyone can verify a proof using a public link. No account needed.

One API call

Anchor an event, document, or AI output with a single POST request. SDKs for Python, Node.js, and cURL.

Built for teams that can't afford to explain

Finance & operations

Anchor payments, approvals, and transactions. When regulators ask what happened, show them proof — not screenshots.

Legal & compliance

7-year retention, immutable audit trails, public verification. Designed for SOX, HIPAA, and EU AI Act from day one.

Engineering teams

One API call to anchor. SDKs for Python and Node.js. Free tier with 1,000 events/month. Ship proof infrastructure in an afternoon.

Simple, usage-based pricing

Pay for proofs created, not seats or dashboards. Start free. Scale when you need to.

Invoance provides technical verification and proof infrastructure for digital records. Invoance does not issue legal, financial, or regulatory advice.

Records anchored through Invoance are cryptographically signed and tamper-evident by design. Invoance does not verify the accuracy, legality, or authenticity of document contents — only that a record existed in a specific form at a specific time. Verification links are publicly resolvable and do not require authentication. Invoance does not act as a custodian of funds, a legal authority, or a regulated financial entity. Use of Invoance does not constitute legal compliance. Consult qualified counsel for your specific obligations.
