I want to add a new column "labour" in sales voucher to calculate total by multiplying labour x Rate and print in sale invoice.
there are many customized SALES vouchers here....e.g. Garment Invoice, Jewellery Invoice.... You can search for them and use that code and remodify it for your purposes. If you run into any problems during the re-coding/ modifying ................then you can post your errors here and experts will help you out.
