Flexible scheduling is one of the most requested features in any appointment-based business, and the Bookly Custom Duration (Add-on) delivers exactly that. Built as an extension for the widely used Bookly PRO booking system, this add-on hands control of appointment length directly to the client. Instead of forcing every customer into a fixed time slot, the plugin lets them decide how many units of time they need, with the price recalculated automatically. It is designed for WordPress site owners running service businesses where session length genuinely varies — consultants, coaches, clinics, conference organizers, and anyone whose bookings do not fit neatly into a single predefined block. Developed by Nota-info and available on CodeCanyon for $39.00, it has already been purchased 1,846 times, making it one of the more trusted add-ons in the Bookly ecosystem.
Key Features
- Time-flexible services: Convert any standard Bookly service into one where the duration is not fixed in advance. Clients choose how long they want the appointment to run, which is ideal for meetings, consultations, and conferences that rarely fit a rigid template.
- Client-controlled appointment length: The duration selector appears at the start of the booking process inside the standard Bookly form, so customers make the decision before confirming rather than after. This keeps the booking flow familiar and intuitive.
- Automatic price calculation: Once a client selects their preferred duration, the plugin calculates the total cost on the fly based on the service’s configured pricing. There is no manual quoting and no back-and-forth with the customer.
- Unified calendar display: Bookings made with flexible durations appear in the Bookly Calendar as a single appointment, with a clear indication of how many units were booked. This keeps the admin schedule readable instead of cluttering it with fragmented entries.
- Seamless Bookly PRO integration: Like every official Bookly add-on, setup takes only a few minutes and slots directly into the existing Bookly PRO dashboard, settings, and shortcodes. No custom development or theme modification is required.
- Documentation and video support: Nota-info provides detailed written documentation plus quick video tutorials, so even non-technical site owners can configure the feature without guesswork.
Who Is This For? Use Cases
The Bookly Custom Duration (Add-on) solves a very specific problem: services where the time required is genuinely unpredictable. Any business that has ever told a client “it depends on what you need” will find immediate value here.
Consultants, Coaches, and Agencies
Professional service providers often bill by the hour or by the session, and clients frequently need more or less time than a default slot allows. With flexible duration, a consultant can offer a 60-minute base session and let the client extend it to 90 or 120 minutes, with the price adjusting automatically. Agencies managing multiple stakeholder meetings benefit from the same flexibility.
Clinics and Wellness Practitioners
Therapy sessions, physiotherapy appointments, and wellness treatments vary significantly from client to client. Rather than creating five separate services for every possible duration, practitioners can create one flexible service and let the patient choose. This reduces admin overhead and eliminates double-booking errors caused by mismatched time slots.
Conference and Event Organizers
Meetings, workshops, and conference sessions rarely conform to a fixed block. Organizers using Bookly PRO to manage room or speaker bookings can allow attendees or staff to select the exact duration required, while the calendar still shows each booking as one coherent entry with its unit count.
Freelancers and Solo Service Providers
Freelancers who sell their time directly — designers, developers, tutors, photographers — can offer a single flexible service instead of maintaining a confusing menu of duration options. Clients self-select, the price is calculated instantly, and the freelancer’s calendar stays clean.
Developers and Site Builders
Developers building booking sites for clients can deploy this add-on as a value-added feature without writing custom code. Because it integrates natively with Bookly PRO, it fits into existing project workflows and is easy to hand off with documentation included.
Technical Details & Compatibility
The Bookly Custom Duration (Add-on) is a WordPress plugin built specifically for the Bookly ecosystem. It requires the Bookly PRO plugin to be installed and active — it will not function as a standalone product. This dependency is standard across all Bookly add-ons and ensures the custom duration feature inherits the same booking engine, payment gateways, and notification systems that Bookly PRO already provides.
Because it plugs directly into Bookly PRO, the add-on works with the same themes, page builders, and shortcodes that Bookly supports, including Gutenberg and popular page builders used in WordPress booking sites. The booking form itself is responsive and mobile-friendly, so clients can select their duration just as easily on a phone as on a desktop. The admin calendar interface is accessed through the WordPress dashboard and follows the same browser compatibility standards as Bookly PRO itself.
Performance impact is minimal since the add-on extends existing Bookly functionality rather than introducing a separate booking engine. Installation is handled through the standard WordPress plugin upload process, and configuration takes only a few minutes thanks to the included documentation and video tutorials. Nota-info maintains the add-on alongside the wider Bookly add-on family, so updates follow the same release rhythm as the core product.
Pros and Cons
Pros
- Genuine flexibility for clients: Customers choose their own appointment length, which reduces friction and improves conversion on services where time requirements vary.
- Automatic pricing removes manual work: No quotes, no email back-and-forth, no invoicing errors — the price updates the moment a duration is selected.
- Clean calendar management: Flexible bookings appear as a single appointment with a unit count, keeping the admin view readable.
- Fast setup: Installation and configuration take only a few minutes, and Nota-info provides both written documentation and video tutorials.
- Excellent value at $39.00: A one-time purchase that unlocks a feature many booking businesses consider essential, with no recurring fee.
- Proven track record: Over 1,800 sales on CodeCanyon signals strong adoption and community trust.
- Native Bookly PRO integration: No custom coding, no theme conflicts, no separate booking flow to maintain.
Cons
- Requires Bookly PRO: This is an add-on, not a standalone plugin. Buyers must already own or purchase Bookly PRO, which adds to the total cost.
- Niche functionality: Businesses with fixed-length services will not need this add-on at all.
- Limited to the Bookly ecosystem: It cannot be used with other WordPress booking plugins.
- No standalone rating data: Because it is sold as an add-on, it does not carry the same volume of public reviews as the core Bookly PRO product, so buyers rely more on documentation and the developer’s reputation.
Frequently Asked Questions
Do I need Bookly PRO to use the Bookly Custom Duration (Add-on)?
Yes. The Bookly Custom Duration (Add-on) is an extension and will not work on its own. You must have the Bookly PRO Appointment Booking and Scheduling Software System installed and activated on your WordPress site before this add-on can function. If you do not yet own Bookly PRO, you will need to purchase it separately.
How does the automatic price calculation work for flexible durations?
When a client selects how long they want their appointment to last, the add-on calculates the total price based on the service’s configured pricing in Bookly PRO. The price updates within the booking form before the client confirms, so there are no surprises at checkout and no manual invoicing required from the business owner.
How do flexible-duration bookings appear in the Bookly Calendar?
Rather than splitting a long appointment into multiple entries, the add-on displays each flexible booking as a single appointment in the Bookly Calendar, along with a clear indication of how many units were booked. This keeps the schedule easy to read and helps administrators understand at a glance how much time each client has reserved.
Final Verdict
The Bookly Custom Duration (Add-on) is a focused, well-executed solution to a real problem in appointment-based businesses: not every booking fits a fixed time slot. By letting clients choose their own duration and calculating the price automatically, it removes a significant source of friction from the booking process while keeping the admin calendar clean and readable. The 1,846 sales on CodeCanyon are a strong indicator that Nota-info has built something the Bookly community genuinely needs, and the developer’s track record with the wider Bookly add-on suite adds further credibility.
At $39.00 as a one-time purchase, the value proposition is straightforward. If your business offers services where time requirements vary — consultations, meetings, therapy sessions, workshops, or freelance work — this add-on pays for itself the first time a client books a longer appointment without you having to intervene manually. Setup takes minutes, documentation is included, and it integrates natively with Bookly PRO.
If you already run Bookly PRO and want to give your clients more control over their bookings, the Bookly Custom Duration (Add-on) is the logical next step. Purchase it on CodeCanyon today, install it in minutes, and start offering time-flexible services that adapt to what your clients actually need.
