User Manual: Auto Withholding Tax Journal upon Purchase of Specific Non-Stock Items (Service Items)

This user manual describes the functionality and use of the script that automates the creation of withholding tax journal entries in ERPNext for purchases of specific non-stock items (service items).

Overview

The script automates the creation of journal entries for withholding tax based on the purchase of items with a defined withholding tax rate. It ensures compliance by linking the journal entry to the respective purchase invoice and accounts for multi-currency scenarios. This feature is particularly useful for businesses needing to manage withholding tax obligations efficiently.
