and one customer buy all above three products tax calculated on the basis of individual products because price are vary and we dont compile this like 17+10+5,

because we want to show all details like breakup to customer.

because in ITEM section we can do ' item type tax ' for ex; taxable
in customer section we give rates.

Please read the wiki

i have take a look in it but i think we can manage in PURCHASE SECTION but in sales section how can do that because it must be attached with INVOICE GENERATING AREA where we make e.g Direct Invoice or etc.

how can? any idea?

can you please help me for this because we want some logically taxes

e.g we imported items from abroad and taxes is

1. Sales Tax (17% of value of import)
2. AST (3% of value of import + Custom Duty)
3. Custom Duties (25% of value of import)
4. Income Tax (6% of value of import + Custom Duty + Sales Tax)

this individual can be set at tax setup area but the problem is the rate

can you please help me how can i implement AST & INCOME TAX,

secondly, when we sales item,
our items includes different rate

e.g

1. Sales Tax (17% of sales)
1.1A. Excessive Item (3% of sales)
2. Zero Rated (0% of sales)
3. AST for Non-registered users / Further Tax 1% of sales
4. Income Tax (6% of sales + Sales Tax)

this things various because when we sale product A, B, & C these product are different types so how can we manage INCOME TAX & ZERO RATES and EXCESSIVE ITEMS

because these various product to product

e.g product A applies 1-3
e.g product B applies 2-3
e.g product C applies 1 & 4

your sales system calculate total value on which taxes is calculated.

any idea for this..
