Why venues switch

The problems we exist to end

No per-bay pricing

Sim software charges per bay, so growing costs you more. Caldekins is one price for the venue — add bays, pay the same.

Open as late as you like

If your bays can run unstaffed — the evening after the desk closes, or fully 24/7 — bookings carry a door code and members let themselves in. Inside a club that shuts at nine? It simply runs to your hours.

Deposits that stick

Card-backed bookings with cancellation windows, so a no-show on a Friday-night bay doesn't cost you the slot and the revenue.

What you get

Built for the way your venue runs

Bay & duration booking

Players pick a bay, a tee-off time and a duration — 30, 60 or 120 minutes — with live availability.

Peak & off-peak bands

Evening and weekend rates, cheaper daytime range hours — the same bay sold as different products, priced automatically.

Memberships that mean access

Not just a discount: unlimited off-peak, a monthly allowance of peak hours, a priority booking window — and door entry outside staffed hours, up to 24/7 if your venue allows it.

Door codes per booking

Every confirmation can carry its own entry code, valid for that slot — for after-hours sessions or all-hours venues. Works with inexpensive smart locks — no integration project required.

Lessons & coaching

Pro lessons bookable alongside bays, with the coach's own diary in the staff CRM.

Gift vouchers

Monetary or session vouchers sold online, redeemed at booking — plus front-desk POS the day you add staff and a bar.

The unstaffed engine

Your bays can earn while the desk is closed

The venues making sim economics work stretch their hours — staffed-lite evenings, or fully unstaffed 24/7 where the building allows it. Caldekins is the member of staff for those hours: door codes with bookings, entry gated on membership, no-show rules enforced automatically. Run normal opening hours instead? Everything works the same — the staff-only modules like rota and till just show or hide to match how you operate.

  • Entry codes on bookings — for after-hours or all-hours
  • Membership-gated door access, up to 24/7 where the venue allows
  • POS and F&B modules on or off to match how you staff
