US hospitality, travel, and rental acquirers, processors, PayFacs, and ISOs: the first full billing cycles since Mastercard's April 1 change to the Not Reversed or Cleared Preauthorization criteria are behind us. Exposure is now measurable.
The fee isn't new. The criteria changed, and one of the changes works in your favor.
First, a preauthorization followed by one or more properly linked incremental preauthorizations is now excluded from this TPE criterion. If your hospitality merchant runs the proper flow, initial preauthorization, incrementals as the stay or rental extends, then final clearing, the original preauthorization falls outside the fee. Clean win for portfolios with mature authorization practices.
Second, where no clearing message is submitted and no exclusion applies, the acquirer must ensure a full reversal is submitted within 30 calendar days of the original authorization date. Miss that and the original preauthorization can become a fee event.
Worth being explicit with merchants on this one. Thirty days is the fee boundary, not the operating standard. Mastercard's rules still call for a reversal within 24 hours of a cancelled transaction, and where the transaction finalizes below the authorized amount, either a partial reversal or the clearing record inside 24 hours.
Where it shows up: hotel stays cancelled or shortened after authorization, vehicle rentals cancelled or shortened after the initial authorization, and cruise folios where an initial or incremental authorization was never properly cleared or reversed.
The fee isn't punishing anyone with clean operations. It's punishing acquirers whose merchants leave stale authorizations sitting on the system.
Many acquirers pass TPE through, so whether the merchant ultimately pays depends on the pricing schedule, and an ISO's direct exposure depends on its processing agreement. But the obligation sits with the acquirer under Mastercard's rules. And across a hospitality book these fees compound quietly, with no obvious source line for a relationship manager to chase.
This week: pull approved Mastercard preauthorizations for your top 20 US merchants in these verticals, from April 1 through the most recent transactions now at least 31 days old. Flag anything with no matched clearing and no full reversal inside 30 days. Then separate out the ones followed by properly linked incremental authorizations, since those originals are now excluded. That is your potential exposure population.
From there, work out where reversal responsibility actually sits across the property management or rental system, gateway, processor, and acquirer. It may touch several of them, and it will need ongoing exception monitoring either way.
One more thing worth raising with the merchant: properly linked incremental authorizations can also extend the message reason code 4808 chargeback protection period. The conversation is an easy one.
And if you can't produce that exposure population quickly, that's the first control gap to fix.
