Billing records and notifications

Billing records answer what changed the Service Credit ledger. Notifications help you notice an event; they are not the authoritative record and may arrive later.

Read records

In Ledger, match purchases, reserves, final charges, releases, refunds, plan fees, and usage charges to their stable references. Invoice and receipt previews, when a Stripe customer exists, live on Account and link out to Stripe; Liskov does not store card numbers or invoice PDFs. Export CSV from Ledger for your own records. Keep your organization's exported receipts with its financial records.

When Stripe supplies a verified tax decomposition, an invoice preview shows the subtotal before tax, VAT/tax, and total. A historical invoice without that provider fact omits the breakdown rather than displaying zero tax. The Stripe hosted/PDF invoice remains the document of record.

The CLI transaction read is safe for automation:

proof liskov organization billing transactions ORGANIZATION_ID \
  --limit 100 \
  --json

Treat transaction IDs, amounts, currency, status, related Application and deployment IDs, timestamps, and evidence references as the audit facts.

Configure notifications

Open Notifications. The supported v1 delivery path is a linked Telegram chat with personal category toggles. Follow the Console instruction to send /connect to @liskov_by_proof_bot, then confirm the channel shows Connected. Enable only categories the Console lists as active; the current active set covers deployment failure and success, operator actions, configuration changes, replacement state, team events, billing, and settlement.

Email, webhooks, spend-gate and budget-threshold alerts, security alerts, digests, and delivery scheduling may be visible but are not active v1 controls. Do not treat an inactive control as a promise. Never put a secret or full billing instrument in a notification destination. For a shared Telegram destination, control membership at Telegram as well as in Liskov.

Verify

Save the preference and confirm its persisted state, then verify the next harmless matching event in the linked Telegram chat. Always open Liskov to confirm posture or financial state before acting on a message.

For support, share transaction and Application identifiers—not card details, secret values, or bearer tokens.
