Choosing the right property management system (PMS) can seem daunting, especially with two strong contenders—Clock PMS by Clock and Optima PMS by Priority Software. Both systems aim to streamline your hotel operations, but they differ significantly in their approach, features, and market presence. Your decision hinges on understanding these differences and determining which aligns best with your hotel's needs.
Clock PMS boasts a robust, feature-rich platform with a proven track record and a large, active user base within the hotel industry. Conversely, Optima PMS is an extensive, global solution favored by resorts and chains, but it has fewer recent reviews and a smaller market footprint. Which system will truly elevate your operations?
Clock PMS and Optima PMS both serve as comprehensive hotel management platforms designed to optimize daily operations. Clock offers an all-in-one cloud-based system with reservations, invoicing, guest messaging, and integrations that make managing a busy hotel more straightforward. Optima, meanwhile, emphasizes global connectivity, revenue management, and multi-channel distribution, especially suited for larger or international hotels.
While Clock has a higher overall rating and more recent reviews, Optima is designed with a broader connectivity focus, supporting over 20 global booking sites. Do you prioritize having a user-friendly, feature-rich system with a strong local presence, or a globally connected platform aimed at larger or chain hotels?
If your hotel needs a user-friendly, highly rated PMS with extensive features for smaller to mid-sized properties, go with Clock. Its intuitive interface, quick onboarding, and a strong focus on guest engagement make it ideal for boutique, city center, and independent hotels. If your hotel operates at a larger scale or across multiple locations, and you value global distribution, revenue management, and integration with major OTAs, Optima is the better choice.
Clock’s recent reviews and high ratings (4.8/5 with 251 reviews, 6 in the last 6 months) give it a clear edge for hoteliers seeking proven performance. Optima’s limited recent feedback and smaller review count suggest it’s better suited for larger, international properties prioritizing distribution and automation.
Clock PMS scores a 4.78/5 in ease of use, with reviewers praising its simple interface, fast onboarding, and minimal training time. Users note that new staff find it straightforward, especially compared to more complex systems, with many mentioning it speeds up daily operations.
Optima PMS has a solid 4/5 rating, but with fewer recent reviews, its ease of use appears less certain. Its broader feature set and global focus may introduce complexity for smaller hotels or teams without dedicated IT support.
Edge: Clock PMS.
Clock offers 49 shared features plus 9 exclusive to its platform, including guest profiles, multi-currency, native email marketing, guest app, and messaging tools—features that enhance guest engagement and operational flexibility. It also supports reservation management, invoicing, channel management, and online check-in, making it a comprehensive all-in-one solution.
Optima has 40 verified integrations and a suite tailored for larger properties, including global distribution, revenue management, and automation tools. It also features a marketplace for add-ons, but with fewer unique hotel-centric features compared to Clock.
Edge: Clock PMS.
Clock PMS is highly rated for customer support, with a 4.75/5 score and recent reviews emphasizing quick, helpful responses. Users laude the support team’s responsiveness and the regularity of system updates that improve performance.
Optima PMS also scores 4/5 in support ratings, with users appreciating the assistance but noting that recent reviews are sparse, making it harder to gauge current support quality. Given the volume of Clock’s reviews and recent feedback, Clock’s support is the clear winner.
Edge: Clock PMS.
Clock PMS integrates with 111 verified partners, including major OTAs, revenue management tools, and channel managers like SiteMinder, TrustYou, and Hotel Investor Apps. Its extensive API and numerous third-party connections make it highly adaptable for diverse hotel tech stacks.
Optima PMS connects with 40 verified partners, including key OTAs and global distribution systems such as Booking.com, Agoda, and Expedia. While capable, its smaller ecosystem limits flexibility compared to Clock.
Edge: Clock PMS.
Clock PMS’s 251 reviews, with a 4.8/5 overall rating and 95% likelihood to recommend, showcase a highly satisfied user base. Independent and boutique hotels, which comprise much of its clientele, praise its ease of use and operational efficiencies.
Optima’s limited reviews and a lack of recent feedback make it difficult to assess current satisfaction levels. Its main users are resorts and large properties, but without recent data, the rating comparison favors Clock.
Edge: Clock PMS.
Clock PMS charges a $600 monthly flat fee with no setup or hidden costs, offering transparency and predictable expenses. It does not offer a freemium model or per-room pricing, making it straightforward for budgeting.
Optima PMS’s pricing is not publicly available, typically customized based on property size and features, common for enterprise solutions. Its lack of clear pricing complicates direct comparisons but suggests a focus on larger clients with bespoke arrangements.
Not ideal if your property operates at a very large scale, where global distribution and advanced revenue management are paramount, or if your team prefers a highly customizable, enterprise-level system.
Not ideal if your hotel is small, boutique, or primarily local, where simplicity and quick usability are more important than global integrations.
Clock PMS and Optima PMS serve distinct segments within hotel management. Clock’s strengths lie in its ease of use, feature set, and support, making it well-suited for boutique, independent, and mid-sized hotels. Optima offers extensive distribution and automation capabilities, aligning better with resorts and global chains, though it lacks recent reviews to confirm current performance.
Choose Clock PMS if your hotel values a high-rated, user-friendly platform with proven operational benefits. Opt for Optima if your hotel relies heavily on global distribution, multi-property management, and sophisticated automation, but be aware of its limited recent feedback.
In summary, for most hoteliers evaluating today, Clock PMS emerges as the stronger option thanks to its larger review base, recent positive feedback, and broad feature set. Optima remains a compelling choice for larger, international properties but needs more current user insights to fully endorse.
Note: Pricing details for Optima PMS are not publicly available, which may influence your budgeting process. Clock’s transparent flat fee simplifies cost planning.

| Criteria Group | Weight | What It Measures |
|---|---|---|
| Customer Ratings & Reviews |
|
How highly do users recommend this product? Ratings Score, Review Volume, Share of Voice, Review Depth, Review Recency, Success Stories ▾ The most heavily weighted factor. Analyzes average satisfaction ratings (likelihood to recommend, ease of use, support, ROI), total review count relative to category peers, review recency (at least 20 reviews in the trailing 6 months), and share of voice across unique hotel clients to detect selection bias. |
| Partner Ecosystem |
|
How highly do tech partners recommend this company? Partner Recommendations, Integration Quantity, Integration Quality ▾ Evaluates partner recommendations as expert votes of confidence, the number of verified integrations, and ecosystem quality — the average HT Scores of integration partners. Products with higher-quality integration ecosystems are more likely to deliver a connected tech stack. |
| Customer Centricity |
|
How customer-centric is this organization? Certified Support, Review Consistency, Profile Completeness ▾ Assesses whether the company has earned HTR Customer Support Certification, maintains consistent review collection over time (an indicator of feedback-driven culture), and keeps product profiles complete with capabilities, screenshots, pricing, and features. |
| Reach, Staying Power & Resources |
|
How extensive is this company's reach and resourcing? Geographic Reach, Staying Power, Company Resources, Trending Score ▾ Measures global presence (countries and regions served), years in business as a stability proxy, team headcount as a resource proxy, and a trending score based on trailing-twelve-month buyer inquiries, reviews, partner recommendations, and press activity. |
