Group + Pay = groupay!

groupay is an application that makes it easy to adjust for split bill of group travel, BBQs, and other events.

For example, have you ever experienced the following when traveling in a group?

Mr./Ms. A: paid accommodation expenses
Mr./Ms. B: paid rental car and highway expenses
Mr./Ms. C: paid the entrance expenses
Mr./Ms. D: paid meals expenses
Mr./Ms. E: paid gasoline expenses

When members are advancing various payments like this, it is difficult to calculate who should pay how much to whom when the final settlement is made...

In such a case, groupay makes it easy to know "who should pay whom and how much" in the final settlement by simply inputting "who paid how much".

Also, Mr./Ms. A came from far away, so I want to reduce his payment.
Mr./Ms. B is a midway participant, so I want to give him a discount.

In such cases, the system also has a convenient reduction function.

Furthermore, you may want to split the cost of alcohol with only those who drink.

In such a case, we have also included a function that allows you to select a member for each payment.

Let's use groupay to free yourself from the hassle of complicated calculations when settling your account!

*Depending on the amount of payment and the number of people, the amount per person or the amount of settlement may not be exactly divisible by the number of people, and there may be an error of a few yen.
Please understand.
