VAT tax with third party order processing

Hello,

we are a US company with an office in India. We do not warehouse anything but will only do third-party orders (drop-ship) for India which means goods will be shipped from a third-party vendor directly to the customer. We want to do the tax determination (VAT, service tax etc.) in SAP. Since the taxes depend on the state that the goods ship from, we were told we need to create a plant for each state where we use third-party vendors and use this plant in the sales order line item so that is uses the correct VAT registration number for the state which we maintain for the plant.

Is there any other way to calculate correct taxes in SAP without having to create a plant for each vendor state?

Regards,

Achim
