I'm thinking of introducing your reservation system "Amelia" (paid version).

We run a scuba diving shop.
We mainly offer the following 4-course menu.
Could you please confirm if your reservation system can meet our requirements for our style of selling?

Hi Uroš,

Thank you for your reply!
So...That means Is the following way the only way to realize the price to change depending on the number of people that a person brings?

1. Create a "category" by each service name(=the item name on sale).
2. Create a "service" by the number of people below it.

ex.
Category: [Snorkeling tour]
├ Service: Snorkeling tour for 2 (6,000 yen per person)
├ Service: Snorkeling tour for 3-4 (5,500 yen per person)
└ Service: Snorkeling tour for 5 or more (5,000 yen per person)

And...I have questions.
Can we accept multiple groups in the same time slot on "Amelia"?
If we put 1 reservation in the time slot on "Amelia", can we continue to accept other reservations?

And...In "Amelia", there's a concept that "a representative of the group" and "people he brings" at the occasion of booking for a group.
Can we obtain the aggregate number of participants including "a representative of the group"  at once?

,

> Can you please elaborate on your last question and I will assist you with this?

I want to obtain the total number of participants including an applicant("you") at one time.
But Amelia obtains the number of "You" and "Additional people" from each other in separate steps with the question "Bringing anyone with you?", doesn't it?

If you bring 7person with you,  I want to obtain not the number "1" and "7" but the only total number "8".
Because I want to use the number "8" on my Google calendar.
