3.8 Taxes and Charges

Shipping Rule

A Shipping Rule helps set the cost of shipping an Item. The cost will usually increase with the distance of shipping. To know more, visit the Shipping Rule page.

Purchase Order Taxes

For example, you buy Items worth X and sell them for 1.3X. So your Customer pays 1.3 times the tax you pay your Supplier. Since you have already paid tax to your Supplier for X, what you owe your government is only the tax on 0.3X.

This is very easy to track in ERPNext since each tax head is also an Account. Ideally you must create two Accounts for each type of VAT you pay and collect, “Purchase VAT-X” (asset) and “Sales VAT-X” (liability), or something to that effect.

3.9 Additional Discount

Other than recording discount per item, you can add a discount to the whole purchase order in this section. This discount could be based on the Grand Total i.e., post tax/charges or Net total i.e., pre tax/charges. The additional discount can be applied as a percentage or an amount.
