Purchase credit
You can load and view your private sheets, but to calculate them (except the free ones) you must have a positive balance in your account.
After having deposited money in your account, when you start modifying one of your sheets, a small amount of money is taken off from your account after asking your confirmation, and you get modification rights on that sheet over a period of 2 full days.
The amount (euro) so required per sheet is indicated (when due) on the left of each sheet in the menu for your private folders.
So, if you want to purchase credit, just decide how much you want to pay, there's no minimum, and click the button below.
