Use cases
Concrete walk-throughs.
The same twenty primitives compose into very different products. Here are six worked examples — each tells the story of one operator's workflow end to end, naming the primitives at each step.
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 →Restaurant
A dine-in tab on a table held until close, coursed kitchen tickets routed by Daneel, split checks, tip-on-card, and a menu whose recipes decrement inventory.
Read →Fitness studio
Capacity-capped classes with waitlists and check-in, membership tiers and entitlement, class packs as stored value, and recurring dues on a stored credential.
Read →Courier & last-mile
Own-fleet dispatch with zone gating and driver stops, pay-before-dispatch through the needs ledger, live Palver tracking, and a carrier seam that overflows to DoorDash or Uber.
Read →Specialty clinic
A consult → conditional procedure → follow-up journey run as a Daneel DAG, with deposit-to-confirm and approval-to-proceed needs and a Sign consent envelope.
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: equipment rentals, charter fleets, classroom scheduling, urgent-care queues, home-service field crews. Tell us yours.
