How to Choose Stock Value With or Without Tax in myBillBook
Written By Team Flobiz
Last updated 13 days ago
Overview
Stock value directly impacts your Inventory reports, Profit & Loss, and Balance Sheet.
Different businesses - and accountants - treat GST differently:
Some include GST as part of item cost
Others exclude GST and treat it as input credit
Earlier, stock value in myBillBook followed a fixed logic, which caused confusion, mismatched reports, and trust issues.
myBillBook now lets you choose how stock value is calculated - with tax or without tax - and applies this choice consistently across all reports and platforms.
What Is Stock Value Calculation?
Stock Value = Selected Price × Current Stock Quantity
You can choose which price is used:
Purchase Price with Tax
Purchase Price without Tax
Sales Price with Tax
Sales Price without Tax
Example
If Purchase Price = ₹1,000 with 18% GST
👉 Price without tax = ₹847
