Sale tax

Dear Sir;

We have one business at two different cities in one state under one Company and VAT No. 

We do sale transactions from both warehouses to our clients which are situated in two different cities. So Is it possible to have One Sale Series for both warehouses. (Because we have online billing and want to keep one sale series from both warehouses). 

Look forward of your concerns. 

Thanks. 

With Regards,

Sachin Gupta.
