Introduction
Most hotels don't have a guest data problem — they have a guest data fragmentation problem. The same guest books direct, then through an OTA, then through a corporate channel. Each booking creates a new record, and each record holds a slightly different version of the truth. Multiply that across properties and channels, and one guest can become five, ten, or even twenty separate identities in your systems. 😕
Bookboost's Master Profile solves this by automatically clustering all records belonging to the same person into one living, real-time profile. Your team finally sees one guest instead of many fragments — and better data leads to better personalisation and better commercial outcomes across the board. 🏨
Main Concept: What Is Master Profile?
The Master Profile is a consolidated guest record that automatically gathers and clusters individual profiles from different sources — such as PMS integrations, manual entries, or digital reception submissions — into one unified identity.
Key terms to know:
Profile (sub-profile): An individual guest record created from a single data source or interaction. Think of it as a snapshot from one system, at one point in time.
Master Profile: The parent record that links and consolidates all related sub-profiles belonging to the same guest into a single, reliable identity.
Match & Relate: Bookboost's purpose-built identity resolution algorithm. Unlike traditional "match and merge" approaches that overwrite or destroy data, Match & Relate links sub-profiles to a Master Profile while keeping every original record intact — giving you one clean view and full historical context. 🔍
The Master Profile surfaces the most reliable name, email address, and phone number per guest (based on frequency, recency, and source quality), while keeping every underlying sub-profile accessible.
Use Cases
🔄 Eliminate duplicate guest records — Guests booking through multiple channels no longer fragment into multiple identities. Cleaner data, cleaner segmentation, cleaner reporting.
👤 Build a complete guest history across stays and properties — Especially valuable for hotel groups. A guest who's stayed at three of your properties is now one guest with a three-property history, ready for tailored cross-property offers.
📊 Improve segmentation and targeting — Build audiences on richer, deduplicated profiles so your campaigns reach the right person once, not the same person three times.
💬 Personalise messaging based on a full picture — Your CRM, Unified Inbox, and Guest App all read from the Master Profile, so a "welcome back" message is actually a welcome back.
🔗 Link data from multiple PMS or integration sources — Particularly powerful for groups running different PMS instances across properties, or combining PMS data with digital reception, membership portals, and OTAs.
📞 Recover guest details masked by OTAs — Match a redacted OTA booking to a previous direct stay, and the real contact details surface on the Master Profile.
Configuration and Setup
Master Profile is enabled by default for all Bookboost customers — there's nothing to switch on. Once your PMS and other sources are connected, the Match & Relate algorithm starts clustering profiles automatically in the background.
Navigate to Profiles in the left-hand menu of the Bookboost platform.
Click on Guests, find the guest you want to work on, and click the eye icon on the right side.
You will see the Profile (in this case, Mark Davis) and the Subprofile of Mark Davis. Bookboost automatically gathers and links profiles that match the same guest based on identifiers such as email address and phone number.
Review the Master Profile list to see consolidated guest records and the most reliable contact details per guest.
Click on any Master Profile to view all linked sub-profiles, reservation history, and the underlying data points that fed the cluster.
Use the merge or link options (where available) to manually associate profiles that should belong to the same guest but weren't automatically matched — for example, when contact details vary too much for the algorithm to confidently cluster them.
Advanced Setup: What's Next for Master Profile
Master Profile is the foundation for the next wave of Bookboost capabilities:
🤖 AI guest insights directly on the Master Profile — an instant, intelligent summary of who each guest is and what matters to them.
💬 Master Profile context in the Unified Inbox — when a guest reaches out, your team (and the AI Agent) immediately see the full picture across every stay and channel.
🎯 Audience building on Master Profiles — removing the pain of sending campaigns to incorrect or missing contact details.
📈 Master Profiles in Bookboost Insights — so analytics and reporting reflect the real guest count, not the duplicated one.
Conclusion
The Master Profile is a game-changer for hotels that take guest experience and commercial performance seriously. 🌟 By automatically clustering guest data from every source into one living identity — without destroying the underlying records — Bookboost gives your team the cleanest, richest, and most reliable foundation in hospitality. Expect better personalisation, smarter segmentation, stronger direct relationships, and a measurable lift across every campaign and conversation.
If guest data is the asset, the Master Profile is what finally makes it usable.
