Your OTA Math Is Probably Wrong. And It's Costing You.

Ask a hotel GM about their OTA relationship and you'll get a confident answer: commission rates, booking volume, maybe a few war stories about rate parity. Ask them whether every one of last night's OTA reservations settled for the exact right amount, and the confidence disappears.

That gap between "we understand OTAs" and "we can prove every dollar was handled correctly" is the subject of Evention Co-Founder and Chief Strategy Officer Mike Baldinger's recent sit-down with Steve Carran on The Modern Hotelier, recorded live at HITEC San Antonio. It's a conversation worth watching in full, but here's the version that should make finance teams sit up.

One reservation, six versions of the truth

The OTA transaction looks simple from the outside:

Guest books -> Guest pays the OTA -> Hotel gets paid.

But in practice, that one reservation's journey to close looks more like this:

The guest pays the OTA > The hotel charges the OTA issued Virtual Credit Card (VCC) -> Channel Manager > Property Management System -> Payment Processor -> Bank funds the VCC (Sometimes for the full amount, sometimes not) -> General Ledger

Each of these systems keeps its own partial record. Add a short stay, a cancellation, or a front-desk agent charging the wrong card, and reconciliation stops being simple math and starts being an investigation.

$43 million in distributed leakage

Mike explains the nature of distributed leakage and its role in this staggering loss of revenue in the episode: hotels won't ignore one $10,000 problem, but they'll easily ignore a thousand $10 problems scattered across a year of stays. Reviewed at the summary level, which is how most hotels check their OTA books, an overcharge in one column can quietly appear to offset an undercharge in another. The totals look clean. The settlements are not.

Those numbers only capture the direct leakage, underpaid VCCs, overpaid commissions, missed taxes and resort fees. The part that surprises most operators, Mike notes "...isn't the dollars. It's what happens after a guest gets double-charged: a chargeback, a public review, a dent in ADR that follows the property for months."

"This is not a back-office accounting problem. This is strategic financial risk that belongs on their risk register because it touches revenue, the guest experience, and brand reputation simultaneously."

— Mike Baldinger, Co-Founder & Chief Strategy Officer, Evention

A two-question audit any GM can run this week

The most actionable part of the conversation is the simplest. Mike suggests every GM or CFO ask their finance team two questions:

• Are we validating OTA reservations at the summary level, or down to the individual room rate, tax, and resort fee?
• Are we certain every guest was charged correctly for every stay, not just that the totals reconcile?

And for a free gut-check today: search Booking.com or Expedia reviews for your own property using terms like "double charge" or "resort fee." Mike points out that public reviews are often the first hard evidence that OTA settlement is breaking down behind the scenes.

Why Evention is "The Financial Trust Layer", not a reconciliation tool

Reconciliation tools compare numbers after the fact. Mike describes Evention's role as something that sits underneath every financial process and continuously validates each dollar, across POS, PMS, payment processors, and banks, so operators can answer what was booked, what was paid, what was funded, and what was charged, without spreadsheets after checkout.

The full 15-minute conversation gets into how OTA disputes actually get resolved, why hotels aren't as outmatched by OTA timelines as they think, and what "trust after checkout" looks like in practice for a multi-property portfolio. Worth the watch before your next finance meeting.
