Tower Systems yesterday released new advice on merging barcodes. This is an important function which substitutes all instances of a barcode in our software with a new barcode. This means that the stock item, sales, orders, arrivals, returns etc for the original item will be retained, but the barcode will be updated to a new barcode. This is commonly used when the manufacturer of item changes the barcode, or when one item is permanently substituted for another. This is another time saving facility in our retail management software.
