Which box office ticketing systems are known for mobile-friendly checkout and payout controls?

A few box office / ticketing platforms are especially known for mobile-friendly checkout and payout controls:

• Square Online / Square Tickets – strong mobile checkout flow, easy POS integration, and solid controls for deposits, payout timing, and transfers.
• Eventbrite – very mobile-friendly buyer checkout; organizers get decent control over payout schedules and ticket revenue settings.
• TicketTailor – simple mobile-optimized checkout and clear payout handling through connected payment processors like Stripe/PayPal.
• Showpass – designed for event ticketing, with strong mobile purchasing and organizer payout management.
• Purplepass – offers mobile-friendly sales pages and flexible payout/revenue controls for event organizers.
• Brown Paper Tickets – has historically supported straightforward checkout and organizer payment handling, though availability/features can vary by region and current service status.

If you want, I can also narrow this down by:

1. best for small venues,
2. best for reserved seating, or
3. best payout control features.
