SiteMinder delivers inconsistent experiences with strong support from individual agents offset by systemic billing issues, technical bugs, and poor front-line support responsiveness that frustrate many users despite a 3.9/5 rating.

Not a serious company, plenty of options out there.
Impossible to get back ur money if u wrongly play it. Unless u have no issue with money, please don't try.
Connectivity issues (last year), billing, almost non existant customer service. I have been trying for 2 months to get refunded for their illegal charges after upgrading to another "product". It didn't work out but they charged me nevertheless (trial period), I had no other choice but to pay otherwise my business would not be able to migrate to another channel manager in between reservations. In addition to that, after cancellation the charge is different that agreed, for the same service. I'm being overcharged on and on and on and good luck getting support by a bot.
Title: Critical Sync Bug & Financial Loss – Unacceptable Support (Case #08567821) Review Text: I strongly advise small property owners to stay away from Little Hotelier / SiteMinder. Their software caused a severe technical overbooking due to a documented system bug, which their support team (Ticket #08567821) refuses to take responsibility for. The Documented Evidence: My system logs (Request ID: 71449ad9...) prove that a 14-night booking ("Mazzaro") was successfully recorded on Jan 4th, 2026. On Jan 20th, 2026, their automated backend process (activate-platform-property on Kubernetes) reset my inventory without performing a Full Sync. This pushed a false "available_count: 1" to Airbnb for dates that were already sold. This bug generated a double booking with Airbnb guest ZH7AK5 (Muriel Morin) and an immediate €106.00 penalty from Airbnb (which I had to dispute myself). Despite my proactive attempts to resolve the issue with the guest, the customer was rightfully frustrated by the chaos caused by Little Hotelier’s software and cancelled the reservation entirely. This resulted in a certified loss of €1,300.00 for my property ("A Casa di Amici"). The technical support closed my case as "resolved" without offering any compensation. Furthermore, their billing department continues to send payment reminders for a service that has caused significant financial and reputational damage to my business. I have already terminated my contract for breach of contract and migrated to a reliable provider (Octorate). If you value your data integrity and professional support, look elsewhere. SiteMinder has proven to be technically unreliable and commercially dismissive. Marco De Pietro Owner of "A Casa di Amici"
Don't even provide iCals!
Very bad communication from this channel manager. I had a subscription for 4 years and have not been informed when new channels were included in their package. The client support did not provide me with the correct information when I decided to leave this manager so I am ending having to pay for my subscription for an additional year.
Terrible customer support. I have been trying to contact them for more than a month now, on every e-mail address I know, but no one ever replies. Sometimes a "person" writes me an e-mail, but if I reply to that, they never reply, just send the original e-mail again, like some weird malfunctioning AI that can only send one specific text. I work in a hotel, and if we trated our guests like this, we would have gone bankrupt years ago.
We decided to give SiteMinder a try after seeing them in Cloudbeds, initially believing it was more of a marketing platform than just a reservation engine. Unfortunately, the entire experience has been deeply disappointing. From the start, their team made promises that turned out to be misleading. They claimed they would significantly enhance our direct reservations, but that never happened. Instead, what followed was a series of frustrating interactions marked by incompetence at every step: from opening the account, to setup, to basic support questions. The first month was especially concerning because they went completely radio silent, leaving us questioning whether we had been scammed. When it came time for our kickoff call, the assigned person did not show up. We were eventually connected to another agent, but they were clearly unprepared and added no real value. We quickly decided to cancel our account, but even that has been a nightmare. We are now dealing with ongoing payment issues related to reservations, and the support team seems almost vindictive in their approach. They have been dismissive, unhelpful, and at times downright sassy. I live in Portugal, a country that is not exactly known for exceptional service, and yet SiteMinder has managed to deliver an experience that is far worse than anything I have ever encountered here. In all my years of dealing with service providers, I have never had such an unpleasant experience. SiteMinder has cost us more time, energy, and frustration than any company I have ever dealt with. If you are considering them, I would strongly advise looking elsewhere.
Horrible. A huge waste of time. Misrepresentations by their sales team, many limitations and very little value added. A total waste of time and money setting it up to find out that it didn't work. Also their channel manager, calendar is super basic and limited functionality. They themselves admit it but only when issues come up. Also, if you don't continue after the trial, they hold your platforms, ie Airbnb etc hostage. They block access to make changes and airbnb can't unlock or disconnect siteminder. I got a double booking because of it. They are being sued because of this.
Avoid at all cost. Their service barely works, after canceling my subscription for this fact, i am now getting (3 months after the fact already) harassment emails for fictitious invoices and they don't follow GDPR and data privacy/credit card safety regulations.
