Guest CRM & Customer Data Platform

Introduction

Every sale, booking, online order and WiFi login leaves a trace of a guest, but each system keeps its own copy. A guest CRM (customer relationship management, a database of who your guests are) or customer data platform pulls those traces into one profile. You can then see how often someone visits, what they spend and what they order. That lets you split guests into groups, such as lapsed regulars or birthday visitors, and send them messages that fit. Some products stop at the database, while others include email, text, loyalty and reviews. The category is varied: booking systems with a built-in guest book sit beside data platforms built for chains.

Who needs it

Restaurants with more than a few hundred repeat guests, and groups that want one profile across sites and channels. It becomes worthwhile once your data is spread across a POS, a booking tool and an ordering system, and you cannot answer basic questions about who your best customers are.
