If you are in a group on vacation, it is often happens that pays not the one who bought something, but someone who had the money at this moment.
Some people in the group may be a family and someone can be alone.
Writing in a notebook and subsequent calculations require a time and can cause controversy.

The program supports the following types of payments:

- Shared payments.
The amount that one has to pay depends on a participation ratio.
A coefficient, or a factor, is the weight of baggage, the amount eaten muffins and the like.
Alternatively: a taxi or a deck chair rent payment on a beach.
In this case, the factor is an arbitrary number, for example, adults may have a factor of 1, a child may have 0.5.

- Common payments.
Everyone knows how much they have to pay and pays for themself.
This could be, for example, a bill payment at the restaurant.

- Transfer of money.
Someone gave someone money.
