Rule basics
Rules turn a zone into bookable slots — set cutoffs, lead time, capacity, and a recurring schedule.
What a rule controls
A rule attaches to a zone and generates slots on a schedule. Every rule has four required settings:
| Setting | What it does |
|---|---|
| Schedule | Which days of the week the rule generates slots for. |
| Cutoff time | The latest time same-day slots stay bookable. |
| Lead time | Minimum notice before the earliest bookable slot. |
| Capacity | Orders a single slot can hold before it shows as full. |
Multiple rules per zone
A zone can hold more than one rule — for example a tighter weekday schedule and a shorter weekend one. SlotSmith generates slots from every active rule on a zone and merges them into a single list on the storefront.
Capacity of zero
Setting capacity to 0 marks a rule as uncapped — slots never show as full, regardless of booking volume. This is distinct from a low capacity number and is treated as an explicit flag, not “no room.”
