we are new to Zoho. We have a typical issue. we support SEZ zone company. we are supposed to raise the estimate without adding tax to them to get a purchase order. the company internally avoids passing tax components to them and we invoice the same with tax while submitting the final invoice during delivery. we need a solution immediately to use the product. where if we do zero percent we get line item gst as 0%, it misinterprets the case. kindly provide an alternative solution.
