It will be difficult to link between “Advance Receipt Voucher” and invoices in case of sales billing on Cash Sale (Rail/Road)/e-Auction etc., especially in case of Rail Cash sale, where purchasers deposit money in advance to the tune of many crores for which lifting of coal has to be made from various loading point and time. In such situation how will the billing person at one point realize how much “balance advance” is available for adjustment while raising invoice at his end at a specific point of time

Under GST gross amount of advance is to be reported and tax has to be paid. Advance can be adjusted in totality. While raising the invoice subsequent to receipt of advance, the tax payable will get reduced by the amount of tax paid on the advance and balance amount of advance may be adjusted against future supplies.
