18 OTA + GDS Channel Adapters — No Third-Party Channel Manager Tax

Channel sync — resilient by design:

  • Automatically detects when a channel connection is failing and pauses syncing to it, retrying safely once it recovers — so one OTA outage never cascades into a booking crisis
  • Respects each OTA's own API rate limits automatically — no manual throttling needed
  • Never double-imports the same reservation, even on retry

Push a rate update, and it fans out to every connected channel in parallel:

json { "roomTypeId": "king_std", "dates": ["2026-06-01", "2026-06-30"], "baseRate": 199.0, "restrictions": { "minStay": 2, "closedToArrival": false } }

Check the health of any channel connection at a glance:

json { "status": "success", "latency": 234, "lastSync": "2m ago" }

GDS Adapters (for corporate groups + travel agencies):

  • Sabre — Hotel Availability API
  • Amadeus — Cloud Services, Hotel Service V5
  • Travelport — Apollo / Galileo, multi-GDS support
  • Shared base session + PNR logic across all three

OTA Adapters (for direct consumer booking):

  • Booking.com — largest direct OTA, API v3
  • Google Hotel Ads — free booking links in search
  • Expedia — Rapid API integration
  • Airbnb — short-term rental
  • VRBO — vacation rental
  • Plus 10 more: Agoda, Hotels.com, TripAdvisor, Priceline, Hostelworld, Despegar (LATAM), Trip.com (China), Trivago, HRS (China), Kayak

Night Audit — 12-Step End-of-Day Close in One Call

Run the full night audit with one action, and get back a structured summary:

A dry-run mode validates every step without posting anything to the ledger, so managers can preview the close before committing it.

json { "status": "completed", "auditLogId": "AUDIT-2026-05-11-001", "businessDate": "2026-05-11", "totals": { "roomCharges": 18450.0, "taxes": 3321.0, "fees": 890.0, "penalties": 150.0 // Early departures, no-shows }, "occupancy": { "roomsSold": 87, "roomsAvailable": 100, "occupancyPct": 0.87, "adr": 212.07, // Average daily rate "revpar": 184.5, // Revenue per available room "oooRooms": 2 // Out of order }, "noShows": 3, "earlyDepartures": 7, "stayovers": 61, "housekeepingTasksCreated": 87, // One per expected checkout "gmBriefing": { "arrivalsCount": 26, "departuresCount": 31, "vipGuests": [ { "name": "Sarah Chen", "reservationId": "res_abc", "roomNumber": "701" } ], "occupancyForecast": 0.91, "nextBusinessDate": "2026-05-12" } }

20+ Sequential Reconciliation Steps:

Reconcile bank 5. Post penalties 11. Post laundry 17. Post city ledger 6. Reconcile payments 12. Post parking 18. Post GL 19. Generate report 20. Close date + HK tasks

Guest Communications — Email/SMS/WhatsApp from One Surface

Provider abstraction across 11 transports:

6 email providers (SendGrid, SES, Mailgun, Postmark, Resend, SMTP), 4 SMS providers (Twilio, Telnyx, Plivo, Vonage), and the WhatsApp Business API — all behind one templating layer with variable substitution:

json { "to": "guest@example.com", "templateId": "pre-arrival", "variables": { "guestName": "Sarah Chen", "roomNumber": "301", "checkInTime": "3:00 PM", "digitalKeyInstructions": "...", "wifiPassword": "Welcome2026" } }

The AI concierge classifies guest intent and either handles it or escalates:

json { "handled": true, "response": "Late checkout confirmed until 2 PM. $35 fee applies." }

If the request is too complex to auto-resolve, it's escalated to your helpdesk with the full conversation context attached.

Guest Lifecycle Communications:

Pre-Arrival (48h): Booking confirmation + digital key instructions + directions Check-In (0h): Room number + key delivery + WiFi + welcome Daily (8 AM): Weather + activities + restaurant hours Evening (6 PM): Tomorrow's weather + checkout reminder + late checkout offer Post-Departure (2h): Thank you + NPS survey + review request

Folio — Real-Time Post/Stay Billing

The shape of a guest folio:

A folio follows the guest from pre-arrival deposit to post-departure settle — every charge in one running ledger:

json { "status": "open", "transactions": [ { "type": "room_charge", "amount": 199.0, "taxAmount": 35.82, "description": "Night 1" }, { "type": "restaurant", "amount": 85.0, "referenceId": "order_abc", "description": "Dinner" }, { "type": "minibar", "amount": 16.0, "description": "2 × beer" }, { "type": "spa", "amount": 120.0, "referenceId": "order_def", "description": "Massage" } ], "payments": [ { "type": "prepayment", "amount": 199.0, "method": "card", "reference": "pi_xxx" } ], "balance": 156.82 }

Restaurant, spa, and minibar charges arrive on the folio in real time as they happen — no manual entry, no clipboard, no reconciliation errors.

At checkout: charge the card, close the folio, notify housekeeping, and expire the digital key — one action.

Yield Management — Rule-Based Yield Pricing

Deterministic rule engine + demand forecasting:

Demand forecasting considers seasonality, local events, competitor comp-set rates, advance booking velocity, and cancellation patterns:

json { "demandLevel": "peak", "predictedOccupancy": 0.94, "compSetPrices": [219, 235, 199], "eventsNearby": ["Jazz Festival"], "recommendedRate": 349 }

Rate computation is deterministic and consistently fast, even during flash-sale traffic spikes:

json { "rate": 329, "appliedRule": "peak_event_adjustment", "reason": "Jazz Festival nearby" }

Frequently Asked Questions

Aeion Hospitality IS the PMS — covering reservations, front office, housekeeping, F&B, channel management, group blocks, and night audit. Most properties run it as their primary system. If you have an existing PMS you need to keep (Opera, Mews), Aeion can run alongside via the OTA-sync layer and own only the channel-manager + AI-driven workflows.

Channel sync maintains bidirectional sync with Booking.com, Expedia, Airbnb, Trip.com, Vrbo, Hostelworld, Google Hotel Ads, and 11 more OTAs. If a channel goes down, sync to that channel pauses and retries with backoff while other channels continue uninterrupted. Reservations land in your PMS within seconds of OTA booking.

The pricing engine starts with industry-baseline curves, then learns from your reservation history over the first 60–90 days. Surfaces demand-elasticity per room type, day-of-week patterns, lead-time decay curves, and event-driven surges (local conferences, sports games). You can override any AI recommendation; overrides feed back into the model.

The housekeeping AI assigns rooms to housekeepers based on building geometry (floor + wing proximity), special-attention flags (VIP, allergen-free, late checkout), and individual housekeeper capacity. Real-time updates as guests check out / extend; the route adjusts mid-shift if priorities shift. Handheld app for status updates.

12-step night audit runs automatically with operator approval gates at key checkpoints — folio close, revenue posting, channel reconciliation, currency revaluation, no-show charges, late-arrival handling. Each step is reversible until the audit closes. Reduces typical 90-minute manual audit to 15 minutes of operator review.

Yes — multi-property tenants are first-class. Each property has its own room inventory, channel-manager config, rate plans, and KPIs. Chain-level reports aggregate across properties; property-level operators see only their property; corporate operators see the rollup.
