The situation. A 40-room boutique property sends roughly 75% of its bookings through OTAs, paying 15–18% commission on each. Its own website takes almost nothing directly — there’s no real-time availability, no integrated booking engine, and payment happens on arrival, so no-shows and last-minute cancellations erode revenue further. What HWS implements. Three connected layers: the PMS as the inventory source of truth, an online booking engine (OBE) wired directly to that inventory with rate parity logic, and an embedded payment layer (Atlas Pay / Payzone) that captures prepayment or guarantees the card at the moment of booking. The OBE pulls live availability from the PMS, and confirmed direct bookings write straight back — no manual re-entry. The impact. • Revenue / margin: every point of OTA share shifted to direct booking converts a 15–18% commission into near-zero acquisition cost. Moving even 15 points of volume to direct is a direct margin gain on that revenue, not a marginal one. • Cash flow & risk: upfront payment capture cuts no-show losses and improves working capital — the property holds the cash instead of waiting for OTA remittance cycles.
