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"],

}
Check the health of any channel connection at a glance:

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.

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"
}

Learn moreFrequently 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.
