I am using Pro 7.2. In California if there is taxable drop ship, We need to add 10% mark-up to the price for taxable amount. for a sample, if the shipment is $100.00 and tax rate is 8%. Normaly, it will be 100.00 plus tax of 8.00 total of 108.00 for the whole invoice. For Drop Ship, the tax should be base on 100.00 plus 10.00 (10% Mark-up) and the tax will be 8% of 110.00 . tax amount will be 8.80 How I can set this up when i enter the sales order? Is there a function for this type of sales tax? Thanks for the help.
