What GuestDiary.com does

GuestDiary.com, operated by AccuBook Limited and headquartered in Donegal Town, Ireland, provides an all-in-one cloud-based hospitality management platform targeted at small and medium-sized hotels, guesthouses, and B&Bs primarily in Ireland and the UK, with active sales presence in France and Vietnam. The platform is built entirely in-house in Donegal and unifies four core modules - Cloud Diary PMS (front desk and reservations), Channel Manager (real-time OTA distribution to Booking.com, Airbnb, Expedia, etc.), Booking Engine (direct website bookings), and Hotel Websites (multilingual, SEO-optimised with live diary integration) - with add-on modules covering EPOS connectivity (CBE Pixelpoint/Innova, ICR Touch, Casio), payments (Stripe-based GuestDiary Pay, Planet Payment Gateway in development), Smart Door Lock integration (Onity, Wieldy, Salto), Payment Links, and a Mobile App for iOS and Android.

The technology stack is fully cloud-native with no on-site server requirement and relies on a single shared database across modules so that availability, rates, and reservations are synchronised in real time. The platform is PCI DSS compliant (with Visa Merchant Agent listing) and GDPR compliant since 2018; it offers 2-of-3 dimensional features such as derived rate plans, low-inventory closeouts, automatic invoicing, multilingual content, and remote door access without app download. Product velocity has been high, with a full mobile app release in March 2026, new door-lock integrations going live in January 2026, and a broader product suite delivered in August 2025.

The business model is predominantly tiered SaaS subscription billed monthly based on room count, ranging from £/€89/month for 1–5 rooms up to £/€229/month for 36–50 rooms with custom pricing above 50 rooms; the offering includes unlimited Irish-based support with no setup, training, or upfront fees. Additional revenue comes from a €3/room/month (minimum €49) Smart Door Lock fee and a 2.9% transaction commission on direct website bookings only (no commission on OTA bookings). Distribution is hybrid: a product-led growth motion via a 90-day free trial with no credit card through the website, complemented by direct field sales from Donegal for Irish and UK mid-market customers, partner resellers/marketing agencies (Back Office Marketing, Marketing for Tourism, Great National Group call centre), and in-region Key Account Managers in France and Vietnam. GuestDiary holds no external disclosed funding and is owned by its founders/management, with R&D co-funded historically by Enterprise Ireland and the European Regional Development Fund.

Broad incumbents
