You can use the export-import feature for this. You can export the price levels and price lists of the required company in XML format, and import it into another company. Before importing the XML file, you need to ensure that the same stock items with UOM are available in the company in which the data needs to be imported. In absence of same stock items and UoMs, the data import will not be successful. The steps to export and import price list is given below:
To Export
Gateway of Tally > Alter > Price List (Stock Group).
Alternatively, press Alt+G (Go To) > Alter Master > type or select Price List (Stock Group) > and press Enter.
Press Alt+E (Export) > select Current.
Press E (Send) to export the data.
To Import
Gateway of Tally > press Alt+O (Import) > Masters.
Enter the path where the exported file exists.
Select the file name to import the data.
