Pricing follows usage
Not assumptions

Invoance charges by event volume, retention duration, and optional file storage. No seats, no dashboards, no mutation incentives. You pay for proof created — not for access to the system.

Append-only on all tiersEd25519 signed on all tiersNo lock-in on proof export
Pricing principles
Usage-based

Costs scale with the number of proofs created, anchored, and retained — not with users or internal workflows.

System-aligned

Pricing reflects real cryptographic operations, RFC 3161 timestamping costs, and storage infrastructure — nothing else.

No lock-in

Proofs remain independently verifiable even after you stop using Invoance. Public verification links carry no subscription dependency.

Billing principles
Volume, retention, and storage only

Invoance charges for event volume, retention duration, and optional file storage. Proof verification is a public, unauthenticated operation on every tier — no fees, no limits.

No mutation incentives

Top-up or upgrade, never silent failure

At 80% of any quota you are notified. At 100% ingestion pauses until you top up or upgrade. No events are silently dropped, no surprise overage invoices. You stay in control.

Predictable billing

Downgrading does not delete data

Ledger entries are immutable and retained until their policy expiry regardless of plan changes. Downgrading only affects future quota and feature access.

Append-only by design

You own your verification bundles

Proof export is not gated. Public verification links remain live independent of subscription status. Ed25519 bundles are downloadable and verifiable offline without any Invoance dependency.

No lock-in

Usage top-up

Hit your limit mid-cycle? Top up instantly without changing your plan. Charges apply immediately, reset at the start of your next billing period.

How it works: When you reach 80% of any quota, an in-app banner notifies you with two options — top up your current allocation or upgrade your plan. Top-ups are charged immediately via Stripe and apply to your current billing cycle only. Unused top-up volume does not roll over.
