User Documentation

When WeCash is started for the first time, it loads a default session which name is displayed in the title bar.

Let’s create a new session!
  1. Select "Sessions" in the main menu to open the session list.
  2. Select "Add session" from the session list.
  3. Indicate the session name and save.

Let’s add our friends!
  1. Select the “Users” menu, to open the user list.
  2. Select “Add a user” from the user list.
  3. Do that for all your friends.
It is not mandatory to add all users before the session starts: you can add users later, WeCash will handle the computation of their share correctly.

Let’s add an expense!

You can create an expense either from the Expense list or from the User list menu. When the expense form opens, you can see two groups of peoples: the creditors, indicating who paid and how much, and the debitors, indicating who is supposed to pay this expense. That’s the way to store debts in the group!
Example: You can simplify paying in the restaurant by paying for (but not inviting) all your friend. In this case, you are the creditor, and everybody is debitor (including yourself, since you also ate there!) Example: You can pay for the fuel of your friends' car without using their car. It's like lending money to a part of your group. In this case you are creditor but you are not debitor since your not using what has been bought.

Now we can add an expense:
  1. Select “Add an expense” from the user or the expense list.
  2. Set the expense name (and optionally its date).
  3. Select the creditor for this expense, and indicate how much he payed (you may also store several creditors if several people payed).
  4. Since the total credits and total debits must be equal, WeCash provides shortcuts for defining debitors:
  • Share the expense equally with all people from the group (let’s say Clément payed fuel that must be counted for everybody)
  • Share the expense equally with a subgroup of people (let’s say Clément payed fuel that must be counted for those who share the same car) Warning! If the creditor also pays for his participation, he should be picked up in the list.
  • Specify a custom share.
The two first options are very usefull since you don’t have to calculate anything by yourself. If you select custom share, keep in mind that the sum of credits must be equal to the sum of debits. Once you’re done, the expense form shows the summary. Click save, and your expense will be stored.

The expense will be available from the user that where implied in: if you check Clément’s profile, you will notice that the “Fuel” expense is in the list of credits (for the paid amount) AND in the debits (for its actual participation).

Let's reimburse everybody!

What you really want to know is: at the end of the holidays week, who should get money back from others, and who owes money to the group?!
The User list give you an immediate view of anybody's share since it provides the balance of each user:
  • a positive balance indicates that the user must get money back from the group
  • a negative balance indicates that the user must give money back to the group
