This calculator block consists of two halves. The left one is called "Incoming", and allows you to enter figures of actual receipts into the system. As soon as the client has paid for part of the estimate items, you, or your accountant, by clicking on the "+" symbol in this part of the block, open the "Create a new arrival" window, in which you deposit the amount of the payment made by the client.

With the help of the right half of the block, which has the name "Outgoing", the Golova user gets the opportunity to add part of his planned expenses to the calculator.

This refers to the costs of maintaining those that are pulled into the system from the sections "Planning" and "Specification". For example, it is convenient to enter here the amounts that the user is going to allocate to pay for the meals of his workers on the site, for a taxi for the project manager, etc. There are also fields here to indicate which part of the planned expenses has already been actually paid. This can be done during the creation of a new expense (click on the "+" symbol in the right half of the block, and in the window that appears, the "Paid (actually)" field). If the payment was made later than the planned expense was created, at any convenient moment, click on the Pencil symbol to open the expense editing window and enter (or adjust) the figure of the actual payment for this article.
