Hi Rebecca and thanks for getting in touch!
Yeah, that is possible, for sure. While Event Tickets Plus is designed for digital ticket sales, you can work around the online portion of this.
For example, Event Tickets Plus integrates with WooCommerce which allows you to create orders manually. That would allow you to enter the order details over the phone, process the payment information, then send the tickets automatically once the order has been completed.
Does that sound like it would work for you? Please let me know. 🙂
Cheers,
Geoff
