Hello there,

Thank you for reaching out to us.

When you have several questions or issues please open a new ticket, and we will help you there. In that way, issues and questions that are related to different subjects will be in separate tickets so other customers or our support agents can find them easily. 

Our policy is to have one issue or question per ticket because of the reasons that are described already.

Thank you for understanding. 

1) I want to change the in-between time from 30 min to 15 min, where should I do this? - In settings general settings set default time slot steo to 15 minutes or 5 minutes
2) paying options: I donot see Ideal payment, how to add this - Unfortunately, currently this feature is not available in Amelia. Amelia itself doesn't handle the payments but we have integration with several payment systems such as: PayPal, Mollie, Stripe, WooCommerce, RazorPay and Square. So you can set this up in Mollie for example and then when you are transferred to Mollie this payment method will show

3) for me the field lastname is not neccesary, how to skip this - You can hide this field in customize section for each booking form

Should you have any further inquiries, we kindly request that you open separate tickets for each question and we will gladly help you there. Our policy is to have one issue or question per ticket. 

We wish you all the best and hope you have a wonderful day ahead.
