GuestUn is a Property Management System (PMS) for the hospitality industry. Based on the available content, it is not a general-purpose office SaaS product, but a system designed around the day-to-day operations of hotels, guesthouses, and resorts. It covers modules such as reservations, arrivals, departures, in-house guests, room status, billing, POS, expenses, accounts receivable, reports, audit logs, and system configuration.
The platform offers a fairly complete operational toolkit. The dashboard provides Revenue, Occupancy, ADR, RevPAR, cancellation rate, guest count, revenue trends, occupancy trends, 30/60/90-day occupancy forecasts, and OTA source analysis. The front desk module supports today’s arrivals, today’s departures, in-house guests, and bulk check-out. The housekeeping module supports room-status filtering and bulk updates for statuses such as Clean, Dirty, Inspected, and Occupied. On the finance side, it includes in-stay charges, payments, deposits, split bills, invoice printing, daily expenses, travel agency/channel partner AR, aging analysis, invoices, collections, and statements. It also provides night audit, audit logs, report export to PDF/CSV/Excel, CSV reservation import, Excel/CSV guest profile import, and CSV data backup.
For third-party integrations, GuestUn explicitly supports AIOsell Channel Manager, allowing inventory, rates, and reservations to be synchronized, and receiving new, modified, and canceled bookings via Reservation Webhook. It supports SMTP email configuration, with examples including Gmail, Office365, Yahoo, and SendGrid. It also supports pre-arrival emails and post-stay review emails, with configurable TripAdvisor or Google Review links. Google Gemini AI is used for passport/ID scanning. For permissions, the system includes Staff, Manager, and Admin roles, and supports both module-level permissions and action permissions such as delete, check-in, and check-out, making it suitable for collaboration across multiple job roles.
The available text does not disclose plans, pricing, free trials, payment methods, or deployment model. It also does not specify security or compliance certifications, backup strategy, SLA, or customer support channels. On the API side, no public developer documentation was found; only AIOsell Webhook and Gemini API Key configuration are mentioned. Before purchasing, buyers should confirm whether it is cloud-hosted, who owns the data, billing cycle, training and migration arrangements, channel management fees, and compatibility with local tax requirements.
GuestUn is suitable for small and mid-sized hotels, guesthouses, and resorts that need an integrated PMS, especially properties with OTA distribution, travel agency credit terms, email automation, and multi-currency invoice requirements. Access from mainland China is unknown. Since it involves services such as Google Gemini and Gmail, some integrations may be limited on domestic Chinese networks. If your operations are mainly in China, you may want to compare it with local PMS products such as 订单来了, 别样红, and 绿云, or international options such as Cloudbeds, Mews, and Little Hotelier.
