When a service has multiple team members and the customer selects No preference, Cowlendar needs to decide which team member receives the booking. The Assignment strategy setting controls that decision.
You can find this setting inside any service that uses team-based availability. Open the service, go to the Availability section, and look for the Assignment strategy dropdown below your team member list.
There are three strategies to choose from: Round-robin, Least bookings, and Random. Each one distributes bookings differently. The right choice depends on how your business operates.
Round-robin
Round-robin distributes bookings evenly across your team by alternating between available team members on the calendar itself.
How round-robin actually works
Round-robin does not look at past bookings. It does not check whose turn it was or who received the last booking. It does something simpler and more predictable.
It takes the list of time slots shown to the customer, such as 9:00, 9:30, 10:00, and 10:30, then alternates between the available team members in order.
Slot 1 (9:00) -> Theo
Slot 2 (9:30) -> Luna
Slot 3 (10:00) -> Sofia
Slot 4 (10:30) -> Theo
Slot 5 (11:00) -> Luna
Slot 6 (11:30) -> Sofia
This rotation is based on the displayed time slots, not on previous bookings. The customer sees only the slot that has already been assigned to a team member. From the customer's perspective, they simply pick a time, and Cowlendar already knows who should handle it.
What if a team member is unavailable for a specific slot?
That team member is skipped for that slot. Round-robin only chooses among team members who are actually available at that time.
For example, if at 14:00 only Theo and Luna are free because Sofia has that time blocked, the rotation alternates between Theo and Luna. Sofia does not appear as a candidate for that slot.
Slot at 14:00 -> Theo (Sofia unavailable, skipped)
Slot at 14:30 -> Luna (Sofia unavailable, skipped)
Slot at 15:00 -> Sofia (Sofia is back, rotation resumes with 3 people)
When to use round-robin
Round-robin works best when your team members offer the same service at the same quality level and you want to spread the workload evenly across the visible calendar. It is the most common choice for salons, clinics, and consulting teams where customers do not have a strong provider preference.
Least bookings
Least bookings assigns each time slot to the team member who currently has the fewest confirmed bookings. This strategy actively balances the workload based on real booking data, not just slot rotation.
How least bookings works
When a customer opens the calendar and looks at a time slot, Cowlendar checks which available team members have the fewest existing bookings and assigns that slot to the one with the lowest count.
For example, if Theo has 12 bookings this week, Luna has 8, and Sofia has 10, Cowlendar assigns the next available slot to Luna because she has the lightest load.
When to use least bookings
Least bookings is the best choice when your team members have different schedules or different start dates. If one team member joined mid-week, or if one works fewer days, round-robin would still assign them the same number of slots per visible page, which may not reflect the real booking imbalance. Least bookings corrects this by looking at actual booking counts.
It is also useful when you want to make sure no single team member is overloaded while others sit idle, regardless of how the calendar slots are displayed.
Random
Random assigns each time slot to a randomly selected team member from the pool of available team members for that slot. There is no rotation logic and no active balancing.
How random works
For every time slot, Cowlendar picks one available team member at random. There is no guarantee of even distribution. One team member might receive three slots in a row, and another might receive none for a while. Over a large number of bookings, the distribution tends to even out, but for any specific day or week it can be uneven.
When to use random
Random is the simplest strategy and works when you do not need precise balancing. It is a reasonable default for small teams of 2 or 3 people where minor imbalances do not matter, or for services where all team members are genuinely interchangeable and you just want to avoid always assigning the same person.
The No preference option for customers
The assignment strategy only applies when the customer selects No preference on the booking widget. If the customer picks a specific team member, for example Sofia, the assignment strategy is skipped and the booking goes directly to that team member.
The No preference option is shown at the top of your team member list in the Availability section and is marked as visible. If you hide it, customers will always have to pick a specific team member and the assignment strategy will not be used.
FAQ
Can I change the assignment strategy at any time?
Yes. Open your service, go to Availability, and change the dropdown. The new strategy applies immediately to future bookings. Existing bookings are not affected.
Does round-robin guarantee exactly equal bookings for everyone?
No. Round-robin distributes slots evenly across the visible calendar, but if customers only book certain times of day, or if team members have different availability windows, some team members can still end up with more bookings than others. If equal distribution matters, use Least bookings instead.
What happens if only one team member is available for a time slot?
All three strategies behave the same way. If only one person is available, that person receives the slot. There is no alternative to choose from.
Can I use different strategies for different services?
Yes. Each service has its own independent assignment strategy setting. You could use round-robin for haircuts and least bookings for massages, for example.
