Alion Booking is software for booking and inventory management, combining forms, availability tracking, payment processing, and invoice generation in one system. It manages time slots, equipment, rooms, and overnight stays via customizable booking forms deployable through links, QR codes, or website embeds without plugins. Its pricing engine applies rules based on dates, seasons, holidays, and quantities, offering itemized cost breakdowns. Forms can include payment settings, booking rules, cancellation policies, inventory options, and custom designs. The software automates tasks post-booking, generating tax invoices, sending confirmation emails, and queuing reminders. Integration with platforms like Xero enables automatic data synchronization. Analytics track revenue, booking statuses, payments, and trends like peak days. Payments are processed via Stripe, Square, or PayPal, with funds deposited directly into business accounts.
