With the free version, you’re limited to one event type, yet it offers considerable adaptability. This includes designating meeting venues like Zoom or Google Meet, enabling attendee additions, setting booking horizons, inserting buffer times, and capping daily meetings.

Customization of the scheduling interface is somewhat restricted in the free plan, but it does allow for URL personalization, including for specific events.

The Standard plan or higher elevates your branding options, such as incorporating your company logo while eliminating Calendly’s branding from the booking page.

However, the free plan also includes a feature to display your logo, positioned in the top-left, but doesn’t provide an option to hide Calendly’s branding.

The OnceHub platform allows for extensive personalization of the scheduling process, including meeting types, availability settings, and booking page branding.

Users have the flexibility to customize these forms with additional fields.

For paid meetings, OnceHub integrates with PayPal, allowing direct payment collection at booking and the option to impose a cancellation fee.

Users can also access comprehensive booking reports, summarizing details from any chosen date and time.

These reports are exportable in formats like Excel, CSV, or PDF.

✅ Winner: OnceHub

In-Meeting Tools

Calendly and OnceHub both specialize in simplifying the process of appointment scheduling, offering features that allow users to define availability, automate reminders, and integrate with various calendar platforms. 

However, for additional tasks like note-taking, file-sharing, or live collaboration within meetings, users might need to rely on external tools or applications, as these functions are not inherently included in Calendly or OnceHub.

One key distinction between the two platforms is that Calendly offers a meeting poll feature, which OnceHub does not.

This feature in Calendly assists attendees in determining the most suitable times for meetings.

calendly meeting poll

Users can create and share polls to collect availability preferences from attendees, facilitating the selection of mutually convenient meeting times.

This reduces the need for lengthy back-and-forth communication, thereby enhancing the efficiency of the scheduling process. 

In contrast, OnceHub users would need to coordinate meeting times without this specific polling feature, possibly relying on external methods or tools for consensus.

✅ Winner: Calendly

Meeting Templates

Calendly’s free version offers users the capability to design templates ideal for individual meetings.

Upgrading to a paid subscription unlocks a broader range of features, including the ability to craft specialized templates for different types of meetings like Group, Collective, and Round Robin formats.

These enhanced options allow for tailoring settings and preferences to fit the unique requirements of each meeting type.

Users can establish and apply specific templates for varied meeting situations, thereby simplifying the coordination process for an array of meeting types.

In addition, Calendly offers suggestions on the most appropriate meeting type to match a user’s specific preferences or requirements.

OnceHub offers a selection of pre-set booking templates to accommodate different meeting needs, including options for 15-minute, 30-minute, and 60-minute meetings.

OnceHub meeting templates

These templates provide a quick and efficient way to schedule meetings of standard durations, streamlining the setup process for common appointment types.

Users also have the flexibility to create their own event types tailored to specific needs or preferences.

This customization extends to the visual aspects and organization of the events; users can set unique images or icons for each event type, aiding in easy identification and categorization.

Furthermore, internal tags can be added to these custom events, enhancing the ability to organize and manage various meeting types effectively.

However, it’s important to note that the range of existing templates in OnceHub is somewhat limited.

While the platform offers basic and commonly used durations, users looking for a wider variety of pre-configured templates might find the options somewhat restricted.

Calendly’s scalable nature is showcased through its varied pricing tiers, catering to the growth needs of businesses of different scales.

Its higher-tier packages, particularly aimed at large enterprises, offer features like team scheduling, extensive integrations, and strong security capabilities.

Calendly emphasizes that its enterprise-level solution aids in:

  • Boosting team efficiency.
  • Improving overall business performance and customer interactions.
  • Streamlining and expanding scheduling processes.
  • Providing stringent security for company data.

OnceHub’s scalability in terms of pricing plans is somewhat limited compared to Calendly. It offers only one standard pricing tier at $10 per month per user before progressing to its enterprise or custom plan.

On the other hand, Calendly provides two distinct pricing tiers before escalating to its enterprise-level offerings. 

Despite this limitation in pricing scalability, it’s noteworthy that OnceHub’s enterprise plan shares many features to those offered by Calendly.
