- Offer, price, terms, and disclosure
- Version each offer; show the applicable date, occupancy, currency, price basis, taxes and unavoidable charges, inclusions, exclusions, restrictions, cancellation and modification terms, availability scope, and ranking or sponsorship context where required; preserve guest acceptance and supersession.
- Inventory, holds, and reservation state
- Name the authoritative inventory source, use time-bounded holds, revalidate before commitment, enforce atomic and idempotent transitions, detect duplicates and stale versions, release capacity deliberately, and reconcile channel, reservation and operating states after every material change.
- Guest identity, privacy, and accessible paths
- Collect only necessary guest and party data, record purpose and communication choice, restrict sensitive preferences and accessibility details, provide usable digital and human alternatives, preserve corrections, govern suppliers and channels, and enforce access, retention, deletion and incident response.
- Payment boundary and commercial authority
- Keep cardholder data within approved payment boundaries, store provider references rather than unnecessary account data, separate authorization, capture, settlement and refund, require explicit authority for charges and exceptions, prevent replay, capture receipts, and reconcile finance records.
- Operational handoff, schedule, and service ownership
- Publish current commitments, assign requests and due times, schedule against real capacity and qualifications, preserve accessibility and safety needs, acknowledge guest changes, expose dependencies and supplier acceptance, escalate failures, and record actual delivery rather than task closure alone.
- Change, disruption, recovery, and reconciliation
- Propagate authorized changes across inventory, service, payment and communication; preserve prior state; offer accountable alternatives; support outages and manual operation; prove notification and refund; reconcile booked, served and paid states; keep complaints, corrections and outcome review visible.
