Taxes and Calculation Rules Edit

The Arithmetic operation Rules
We have two primary types of rules, per product and per bill/cart.
Rules per product are calculated for each product shoppers will see these in the product details view and per product listed in the cart.
Rules per bill/cart are using the subtotal of all products and shoppers will see thes in the cart and the cart module.
Each calculation rule is assigned an arithemetic operation type:
- Profit margin
- price modification before tax
- Value Add Tax
- price modification after tax
The price modifications can be used as discounts or for any purpose you can conceive. Any arithmetic operation can be used with any mathematical operation.
Tax is meant for goods which are taxed by weight, unit, or similar.
VAT Tax is recalculated and lowered by given discounts.
Combined with the multi currency system of VirtueMart and the profit margin you can dynamically calculate your desired cost or final price.
Rule configuration options create dependencies/restrictions based on other aspects of your store or shoppers. VirtueMart follows the simple rule that "no entry" means no restriction (Available of all), which means for the most part you can leave configurations empty at first.
- countries / states
- effective dates.
Notes to the rules per bill
Per bill rules only function for categories they do not work for manufacturers.
notes to the vat tax
If you use a "VAT tax per product" for your products, then the VAT tax is lowered if any discount is applied after.
Your shopper's cart is likely to have products with different VAT tax rates in their cart. If a discount or coupon is used, then the VAT tax is lowered in correct relation to the applicable VAT taxes.
You can also use unpublished categories to add a tax to your products and set then the correct category in the VAT tax rules per bill.
Countries and States need the address of the user or some plugin that identifies the users country from their browser detail.
Try Running some configuration tests
Before you start to create your final store It is always worth running a few scenarios for possible options on a test system to fully see the power and possibilities of various configurations , of course, you may need to configure new rules when your store is live to create new business opportunities - but even in this case there is no substitute for trying these out in a test environment,
