Bill books come with duplicate copies. Duplicate copy means it will be 1+1 booklet i.e. 1 parent copy and 1 duplicate copy. These books and vouches are widely used almost in all companies which have not yet shifted to POS invoicing system which generates the bill automatically. Proper maintenance of the record and no major qualification required for using bill books is another advantage. We offer carbon-less paper printing for bill books and vouchers. As name suggests, with these carbon less paper printing you don't require carbon sheets to be inserted between the pages which saves times and looks professional.
