Abstract

A system of accounting for the sale of goods was developed and introduced when payment is made later. For development, we used the cloud version of the Google service - tables. The main requirements to the system and the features of the software implementation are given: multiuser data filtering; volume and speed of recalculation of the table; mechanisms of conditional formatting of cells, protection of cell ranges and verification of data entered into the cell. To protect personal data of customers by installments, the system provides a number of security measures. The functional of the system of accounting for the sale of goods in payment by installments is considered, which is implemented by formulas in cells and formulas in additional mechanisms of Google tables with the use of programming in Google Apps Script - a cloud variant of Java Script.
