HMS Flow Guest CRM & Loyalty

HMS Flow Guest CRM & Loyalty is a hotel-focused tool for managing guest relationships and encouraging repeat stays. It suits lodging properties that want targeted campaigns, automated communications and loyalty offers tied to bookings. Its strongest case is the combination of those functions at a clear annual price for properties with up to 50 rooms; larger properties move to custom pricing.

Overview

The module brings guest records, messaging and loyalty activity into a hotel-oriented workflow. Profiles can combine contact information with stay and spend history, room and rate preferences, staff notes, marketing consent and loyalty tier. That gives teams useful context for service and outreach, but the product is a focused guest CRM rather than a broad sales CRM.

Key features

Automated communications cover booking confirmations, pre-arrival details, in-stay messages, post-stay thanks, review requests and occasion greetings. For properties managing many guest touchpoints, this can make follow-up more consistent; the range is especially relevant where repeat bookings and post-stay engagement matter.

Hotels can define loyalty tiers based on stays or spend, award points on eligible spend and provide member-only rates through the booking engine. Campaign audiences can be filtered by nationality, stay dates, room type, spend, loyalty tier or time since a guest's last visit, then targeted by email or SMS. These tools support segmented, booking-related marketing rather than one-size-fits-all blasts.

Consent is recorded separately for each guest and channel, messages include an unsubscribe option, and profiles can be exported or erased on request. Email and messaging connections include Mailchimp, SendGrid, Brevo, Gmail, SMTP, Netgsm and WhatsApp Business. HMS Flow also describes a REST API with documented endpoints, webhooks and API keys, role-based access, and no-code connections through Zapier. Those options help properties connect the CRM to existing workflows, though they may be more relevant to teams with integration needs than to small operators seeking a standalone contact list.

HMS Flow says guest data is encrypted in transit and at rest, stored on secure cloud servers and backed up daily. Subscription payments use a 256-bit SSL connection with 3D Secure; card details are not stored on HMS Flow servers. These protections address data handling and payment security, but do not replace a property's own responsibility for lawful marketing consent.

Pricing

Plans are billed annually per property, exclude local taxes and include the full platform. The room-band structure makes costs straightforward for smaller properties:

This is useful for a small hotel that wants access to CRM, campaigns and loyalty without stepping up through feature tiers. The trade-off is an annual commitment, and a property with 51 or more rooms must request custom pricing rather than compare against a public rate. There is no free plan; a 14-day free trial and setup help during the trial give prospective customers a limited opportunity to assess fit. 24/7 expert support is included.

Platforms

HMS Flow supports web, Android and iOS, alongside an API. That combination suits teams working across desktop and mobile devices, while the API and Zapier connections offer a route to custom or no-code integrations.

Who it's for

The product is aimed at hotels, resorts, guesthouses, boutique hotels, hostels, B&Bs and apart hotels. It is a strong fit for properties that want guest segmentation, automated communications and loyalty incentives working together. Properties looking for a general-purpose CRM, a free tier, or publicly priced service above 50 rooms should compare alternatives.

Pros and cons

Pros: Guest profiles bring stay context, preferences, staff notes and loyalty information together, supporting more relevant service and marketing.

Pros: Automated guest messages, filtered email or SMS campaigns and booking-engine loyalty rates address several repeat-booking tasks in one hotel module.

Pros: Annual prices are published by room band through 50 rooms, and every priced band includes the full platform.

Cons: There is no free plan, and the 14-day trial is brief for properties that need to assess longer-term campaign or loyalty workflows.

Cons: Annual billing and custom pricing above 50 rooms make costs less flexible or less directly comparable for some buyers.

Alternatives

Hospitality CRM Software is a useful starting point for comparing other products in the category.

GraceSoft Hospitality CRM is worth considering if a free plan is a priority: its Lite tier is free and includes front desk, booking engine, payment gateway, basic reports and email support.

Scidoo CRM may suit buyers who want to request a demo for pricing rather than use a published CRM rate.

PageCRM is an option for teams that want a free starting tier with defined limits, including one team seat, 500 contacts, one WhatsApp instance and 50 AI messages per month.

BookOne CRM is another hospitality-focused alternative.

HoteSoft Guest CRM is worth comparing for a 20-room property: its Starter plan is $299 a year and includes up to three users.

D-EDGE CRM is another paid option to consider.

HAIP may appeal to buyers seeking trigger-based automations, with an AI Automations plan at ₹99 a month per property.

NISKA CRM is another paid CRM to compare.

Verdict

Choose HMS Flow Guest CRM & Loyalty if you run a lodging property of up to 50 rooms and want guest records, targeted communications and loyalty incentives in one hotel-oriented module with published annual pricing. Its principal advantage is the breadth of guest-retention tools across every priced room band. Look elsewhere if you need a free plan, prefer monthly pricing, or have 51 or more rooms and want a public price to compare.
