Use cases
Concrete walk-throughs.
The same eleven primitives compose into very different products. Here are three worked examples — each tells the story of one operator's workflow end to end, naming the primitives at each step.
Golf tee sheet
A pro shop running a daily tee sheet with carts, member tiers, dimensional offers (front nine vs back nine), and tournament exception windows.
Read →Hotel front desk
A boutique hotel running multi-night stays with room types, party check-ins, in-room charges that roll into the folio, and consent-gated guest comms.
Read →Salon & spa
A salon booking variable-duration services against named stylists, with walk-in queues, modifier-driven add-ons, retail product sales, and gratuity on card.
Read →Don't see your shape?
Seldon's five Availability kinds (grid, range, queue, open_capacity, external) plus Hardin's catalog and Hober's order tabs cover most service-business shapes. Other shapes in the back of the mind: fitness class drop-ins, equipment rentals, charter fleets, urgent-care queues, classroom scheduling, multi-stage medical visits. Tell us yours.
