Your PMS stays the same
GuestBrain doesn't touch your operations or make you duplicate manual work: your PMS stays your PMS.
Mews is a PMS: it runs reservations, front desk, billing and hotel operations. GuestBrain is not a PMS and does not replace your PMS. If you use Mews, you keep using it as before; GuestBrain runs the hotel's marketing: CRM, newsletters, campaigns, attribution and guest communication.
GuestBrain doesn't touch your operations or make you duplicate manual work: your PMS stays your PMS.
A single guest profile with their bookings, emails, WhatsApp, WiFi and campaigns; segmented, multi-language newsletters; pre-stay and post-stay automations.
Every direct booking is attributed to the campaign, email or channel that generated it, with its real revenue.
Mews is a cloud PMS. GuestBrain is not a PMS and does not try to replace your PMS: it runs the hotel's marketing. Treating them as substitutes leads to the wrong decision, because they solve different layers of the business.
The PMS runs operations: reservations, check-in, housekeeping, invoicing and guest records. It is the hotel's system of record and should not be swapped lightly.
What a PMS is not built to do is decide how much to spend on Google Ads today, detect that an OTA is selling your room cheaper than your website, or send past guests a segmented newsletter in their language. That commercial layer lives outside the PMS.
GuestBrain builds one profile per guest with their bookings, emails, WhatsApp and campaigns. With that CRM it runs the commercial side: newsletters and pre-stay and post-stay automations, Google Ads and Meta campaigns optimized toward real cost per booking, and attribution of each booking to its channel.
It also monitors parity against OTAs 24/7 with alerts and tracks whether ChatGPT, Gemini or Claude recommend your hotel. Your PMS stays your PMS; GuestBrain runs marketing.
If your issue is PMS cost, the front-desk learning curve or a missing operational module, then you are shopping for another PMS, and the right comparison is with other PMS vendors.
If your issue is "the PMS works fine, but I don't sell enough direct", switching PMS will not fix it. The bottleneck is acquisition, parity and your relationship with guests.
Pull the last 12 months of bookings by channel from your PMS, plus the commission you paid to OTAs. If your direct share looks low for your type of hotel, your problem is commercial, not operational.
Then compare that commission with the cost of a marketing layer: GuestBrain is a flat monthly fee with a fixed price, with no percentage of ad spend. Ask for a proposal.
