Most SiteMinder deployments use maybe a third of the API surface. That is not a criticism of anyone — SiteMinder is deep. But there are five diagnostics you can run in an afternoon that will tell you exactly which extension you would benefit from the most.
Diagnostic 1: How many rate-plan modifications did you make manually last month?
If the answer is more than fifty, you are doing work that Advanced Yield Rules can automate. The threshold for “worth the AU$44/mo” is roughly one manual change per business day.
Diagnostic 2: How long between an OTA sync failure and someone finding out?
Median time-to-discover of eight hours or more means Channel Sync Watchdog will pay for itself in the first prevented commission dispute.
Diagnostic 3: How many of your bookings are direct?
Under 30% and your booking-engine funnel needs a conversion layer. Direct Booking Booster is the module for this.
Diagnostic 4: How often do you look at parity?
If the answer is “when Booking.com complains”, parity is happening to you rather than you managing it. OTA Rate Parity Auditor changes that.
Diagnostic 5: Do you send SiteMinder data to your BI tool?
If not — or if you copy-paste CSVs from a weekly export — Analytics Export Pack replaces a whole afternoon of admin every month for AU$16.
Pick the diagnostic where the answer worries you most. Start there.
