Bookly Custom Duration Add-on

Fixed appointment lengths do not suit every booking business. Bookly Custom Duration Add-on extends the Bookly booking system with service-specific timing controls, giving staff a way to define appointment lengths around the work being scheduled rather than forcing every service into the same pattern.

Flexible service lengths

The central feature is the ability to set a custom duration for each service. That is useful for businesses where the same general type of appointment varies by client requirement, service scope or preparation involved. A salon, clinic or consultancy can keep different timing rules for different services instead of treating every booking as an identical unit.

The add-on also supports multiple services with separate duration settings. This matters more than a single global duration control: the booking structure can reflect a varied service catalogue, with shorter and longer appointments represented independently. Staff can enable or disable custom durations on a per-service basis, so fixed-length services do not need to adopt the new model.

Control in Bookly

Duration changes are handled from the Bookly backend. That keeps the configuration in the same administrative area as the rest of the booking setup, rather than introducing a separate management screen or an unrelated scheduling process. For a team maintaining several services, the per-service switch provides a clear way to decide where custom timing applies.

This backend focus also suits businesses where staff, rather than customers, need to maintain the rules. The add-on is about configuring the appointment structure that Bookly presents, not about replacing the broader booking system. Its value comes from adding a more detailed duration layer to an existing Bookly setup.

What clients encounter

The vendor describes the add-on as preserving a unified Bookly experience. In practical terms, the booking system remains centred on its existing service model while durations become more adaptable. That is a sensible approach for a site that already has Bookly configured and wants to refine appointment timing without introducing a second booking workflow.

Responsive behaviour is also listed as part of the feature set, which supports use across desktop and smaller screens. The vendor further lists compatibility with popular payment gateways, so custom-duration appointments are intended to remain within the normal booking and payment flow rather than requiring a separate transaction process.

What to weigh

This is an add-on, not a standalone appointment system. Sites without Bookly have no stated use for it, and sites with a simple fixed-duration service catalogue may gain little from adding another layer of configuration. The dependency also means the final booking experience is tied to how Bookly handles services, availability and payments; this product’s stated role is limited to customising duration.

Custom timing introduces an administrative trade-off as well. Staff gain finer control, but they also have more service-level settings to maintain. A business with many services will need a clear duration policy to keep those settings consistent. The feature list does not name specific payment gateways or explain how duration changes interact with more advanced Bookly scheduling rules, so those details deserve confirmation before adopting it for a complex booking operation.

Who it suits

Bookly Custom Duration Add-on is aimed at service businesses whose appointments do not fit a dependable fixed slot. It is a good match for a salon, clinic or consulting service that already uses Bookly and needs different timing rules across its catalogue. The strongest case is a varied set of services where staff need per-service control, while businesses with uniform appointment lengths are likely to find the extra configuration unnecessary.
