Hi Lisa
With the annual notice we issue an A4 size sheet with blurb from the waste department that goes down about 3/4 of the page and then perforates into 2 individual vouchers. Each tip voucher has a unique number and a barcode to identify the property it relates to. When they use the vouchers at the tip the barcodes are recorded and then if someone comes in (and they often do) and says they didn’t receive them the girls in waste just do a simple check. If they are adamant that they didn’t receive their vouchers then the original vouchers are cancelled and new ones issued. Saves a lot of arguments.
