The prices of some billed materials or services can increase or decrease due to various reasons such as exchange rate differences, surcharges and commission expenses. Such differences that occur after the invoice is issued are called Price Difference and are separately billed to accounts.
The price differences originating from sales transactions may increase or decrease the sales income. The price difference invoices originating from sales transactions are processed in the Sales and Distribution section. The Sales Price Diff. Invoices are visually similar to other invoice types except for a few fields.
In sales price difference invoices the invoice lines are matched with sales invoices. The lines of the selected sales invoice can be transferred into the price difference invoice except for the Quantity and Amount information.
The price difference amount is distributed into the lines of the invoices matched with the price difference. The distributed price differences are also listed in the Cost Analysis and Inventory Reports, and are processed in profit/loss calculations.
The Sales Price Diff. Invoices are recorded using two methods:
- Using "Apply Price Difference" option in the Sales Invoices window. In this case, the relevant information is automatically transferred into all fields of the Price Difference Invoice. The Related Invoice column displays the information of the invoice to which the price difference will be applied.
- The Sales Price Diff. Invoice is selected as the invoice type in the Sales Invoices window. The information about the price differences are recorded in the Related Invoice Number column after selecting the material / service to which the price different will be applied.

Stock Amounts: The Stock Amounts field located in the middle of the invoice indicates how the material / service will be affected by the price difference. "Increase" or "Decrease" option is selected, and all amount information is processed depending on the selection made. When decrease is selected, the information entered into the Amount field is interpreted as minus 
by the application.

- Will be affected

Transferring Sales Invoices to Sales Invoices
The relevant Material / Service Code must be entered into the invoice line in order to match the sales price diff. invoices with the sales transactions. The matching operation can be performed only after the code entry, and separately for each line.
If the price difference will be applied to the bottom of a specific Sales Invoice, all the invoice lines are transferred using the Invoice Transfer option located in the right mouse button menu, instead of transferring the lines one by one.
The invoices are matched with the sales transactions by invoice date, entering the Start and End Dates. The sales invoices of the AR/AP to which the sales price diff. invoice belongs are listed with the Invoice Number, Date, Type, Aux. Code and Total information. The invoices to be transferred are selected. The information of the lines of the selected invoice is directly transferred into the lines of the sales price diff. invoice.
In the LOGO application, if the sales invoice to be transferred contains material / service lines for which Period Closing is applied, and if the invoice is approved, the invoice is not transferred into the Price Difference Invoice.
Price Difference Amount Distribution
Total Amount can be entered and distributed to material / service lines in the Price Difference Invoice. This transaction is performed using the Amount Distribution option located in the F9 key or right mouse button menu. The lines of the Amount Distribution window display the Material / Service Codes, Distribution Factor, Price Diff. Amount and Total information.
The fields and functions of the window are:
Material (Class) / Service Code: The material and/or service code in the lines of the price diff. invoice (issued).
Distribution Factor: The factor to be used to distribute the price differences to the materials or services in the lines. The distribution factor must be a positive integer.
Price Difference Amount: The price difference amount to be distributed to the lines.
The number of lines in the invoice lines is equal to the number of lines in the Amount Distribution window. When Amount to be Distributed and Total amount are entered, the factors are calculated as follows.
Amount to be distributed = (Total / Distribution Factor Total) * Distribution Factor of the line
The amount information is directly transferred to the invoice when the distribution is completed.
VAT Calculations on Lines: VAT calculations are based on the VAT rates of the materials and/or services in the lines. After the sales invoice lines are transferred into the Price Difference Invoices, VAT Rate in the matched sales transaction is transferred into the line, and can not be changed by the user.
