Sir,
We are manufacturing Pre - Engineered Building and its parts. we are billing in difference units like for roof we bill in KG, M2,M,Square Feet as per customer requirement. Some time we bill for whole shed as per agreement and some times for particular parts only. Our query is how to maintain RG-1 for the same and how can we mentioned it in our ER-1.
thanking you
