The Decision

You're evaluating two property management systems: Clock PMS by Clock and isystems by isystems. Both promise to handle essential hotel operations, but their approaches and market presence differ significantly. Clock PMS offers a broad, feature-rich platform tailored for hotel environments, while isystems targets property managers and real estate professionals with a focus on tenant and routine management. Which system aligns better with your hotel's needs?

Clock PMS is the more established, reviewed, and recent-choice product, boasting a high satisfaction level among hoteliers. isystems, with no recent reviews or ratings, lacks the current user feedback necessary for a confident decision.

Are you seeking an all-in-one hotel platform or a property management tool for larger portfolios? Let's explore how each stacks up for your specific scenario.

Is Clock PMS or isystems better for hotels?

Clock PMS is designed specifically for hotel operations, offering features like booking management, guest messaging, online check-in, and integrated revenue tools, making it a comprehensive solution for busy hotel teams. in contrast, isystems primarily targets property managers and real estate firms, focusing on tenant communication, rent collection, and maintenance, which are less relevant to hotel operations.

Clock’s extensive feature set, including payment processing, channel management, and guest profiles, addresses the core needs of hotels—especially those seeking automation and guest engagement. isystems, lacking specific hospitality features and recent reviews, seems more suited for property management companies managing multiple units or residential portfolios.

Would your hotel benefit from a fully integrated PMS or a system designed for property portfolios? The answer likely favors Clock PMS given its hotel-specific functionalities and recent positive feedback.

Clock PMS vs isystems: Which should your hotel choose?

If your hotel needs a robust, all-in-one platform that handles reservations, rates, invoicing, and guest communication, go with Clock PMS. It’s particularly suitable for boutique hotels, city center properties, and inns that benefit from integrated booking engines, housekeeping modules, and guest engagement tools.

On the other hand, if you manage multiple residential properties, rental units, or focus on tenant relations, isystems might seem appealing—though the lack of recent reviews and hotel-centric features makes it less compelling for hoteliers. The absence of recent user feedback on isystems also diminishes confidence in its ongoing support and functionality for hospitality.

For hoteliers, especially those looking to streamline operations and elevate guest experiences, Clock PMS is the superior choice based on current reviews and feature depth.

Is Clock PMS or isystems easier to use?

Clock PMS scores a 4.78 out of 5 for ease of use, with reviewers highlighting its intuitive interface, quick onboarding, and simple training process. Users report that new staff can be trained rapidly, and daily operations often become more efficient. Its modern, cloud-based design simplifies staff adoption across departments.

isystems has no publicly available ratings or recent reviews, making it impossible to assess its user-friendliness or onboarding experience. Given the lack of recent user feedback, confidence in its ease of use remains unverified.

Edge: Clock PMS.

Which has better features: Clock PMS or isystems?

Clock PMS boasts 58 unique features including booking engine, channel manager, revenue management, guest profiles, integrated CRS, digital registration, and mobile apps—covering all aspects of hotel management. It also offers ancillary revenue tools, automated reminders, advanced reporting, and multi-currency/language support, making it a truly expansive platform.

isystems offers a more limited, unspecified set of features focused on tenant communication, rent collection, and maintenance requests. It lacks hotel-specific functionalities like booking engines, channel management, or guest engagement tools.

Edge: Clock PMS.

Which has better customer support: Clock PMS or isystems?

Clock PMS has a support rating of 4.75 out of 5, with reviews praising its quick, responsive customer service and proactive updates. Users commend the support team’s ability to resolve issues promptly and assist during onboarding.

isystems provides no recent or detailed support feedback, reducing confidence in its customer service quality. The absence of recent reviews makes it hard to judge its responsiveness or support effectiveness.

Edge: Clock PMS.

Which has more integrations: Clock PMS or isystems?

Clock PMS integrates with 111 verified partners, including Curacity, Hotel Investor Apps, FLEXIPASS, and RevControl, offering extensive third-party connectivity. This broad integration ecosystem allows hotels to connect revenue tools, marketing, and distribution channels efficiently.

isystems, lacking verified integration data and partner counts, appears to have minimal or no current integrations. This limits the platform’s ability to connect with other essential hotel systems.

Edge: Clock PMS.

Which do hoteliers rate higher: Clock PMS or isystems?

Clock PMS’s user reviews are recent and plentiful, with a 4.8/5 overall rating from 251 reviews, including 6 reviews in the last 6 months. Its primary users are boutique, city center, and inn properties, which emphasize usability, support, and feature set. Reviewers highlight improvements in operational efficiency and guest satisfaction.

isystems has no recent or publicly available reviews, making it impossible to gauge current user satisfaction. Without current feedback, confidence in its hotel-specific performance remains low.

Edge: Clock PMS.

How much do Clock PMS and isystems cost?

Clock PMS costs $600 per month with no freemium or trial options, offering transparency for budget planning. The pricing structure indicates a subscription fee for an extensive platform with many features.

isystems does not publicly disclose pricing, making it difficult to compare value or determine if the system fits your budget. The lack of transparent pricing suggests it may not be tailored for smaller or mid-sized hotels.

What type of hotel should use Clock PMS?

  • Hotels that need a comprehensive, all-in-one platform for reservations, guest management, and revenue optimization.
  • Boutique hotels, inns, and city center properties that benefit from integrated booking engines and mobile check-in.
  • Hotels seeking automation tools like guest messaging, housekeeping, and dynamic rate management.
  • Teams aiming to reduce manual work and improve operational coordination.
  • Not ideal if your hotel is very small or only needs a simple booking system; extensive features might be overwhelming.

Not ideal if your property operates mainly as a residential or long-term rental, as Clock’s features are tailored for hospitality.

What type of hotel should use isystems?

  • Property managers overseeing multiple units or residential portfolios.
  • Teams focusing primarily on tenant communication, rent collection, and maintenance.
  • Firms that require a straightforward platform for automating routine property management tasks.
  • Not ideal if your hotel needs specific hospitality features like booking engines, guest messaging, or revenue management.
  • Not recommended if you prefer systems with recent reviews, active support, and hotel-centric functionalities.

Given the lack of recent data, isystems appears better suited for property management rather than hospitality.

Clock PMS vs isystems: The bottom line for hotels

Clock PMS is the clear choice for hoteliers seeking a modern, feature-rich property management system. It has a proven track record, with recent reviews emphasizing ease of use, extensive integrations, and strong support, all at a transparent $600 monthly fee.

isystems, lacking recent user feedback and hotel-specific features, seems more appropriate for property managers or real estate firms managing multiple residential units. Its current support and flexibility are unverified, making it less suitable for hotel operations.

If your hotel prioritizes operational efficiency, guest experience, and reliable support, Clock PMS delivers these essentials today. For property portfolios outside the hospitality sector, consider isystems, but with caution due to absent recent reviews.


In conclusion, choose Clock PMS if:

  • You require an all-in-one hotel management platform.
  • Recent reviews confirm high user satisfaction.
  • You value extensive integrations and automation.
  • Your hotel is focused on guest experience and operational efficiency.

Opt for isystems if:

  • You manage multiple residential properties or long-term rentals.
  • Tenant communication and maintenance are your primary needs.
  • You prefer a simple, property-centric management interface.
  • Your decision is less time-sensitive and you can verify current system support.

For hoteliers, the choice largely hinges on current user feedback and feature relevance, which favor Clock PMS.
