Time slots
1 min read
Time slots let customers pick a delivery window β like 10:00β12:00 or 14:00β16:00 β alongside the date.
- Add windows to any rule. Define the slots you offer; they show under the chosen date on the storefront picker.
- Cap each window. Give a slot a capacity and it can sell out independently of the date.
- Live sell-out. Full slots grey out for shoppers automatically, so they only pick what you can fulfill.
- Enforced at checkout. The OrderRules Shopify Function blocks a sold-out slot even on Shop Pay or direct checkout URLs.
Slot windows are carrier-agnostic. At export, they map to each carrier's native slot codes β see Carrier CSV export.
