Your PayPoint till rolls should arrive like clockwork so you are never short. (Assuming you are not a naughty retailer, using them in other terminals, because PP is the only provider to give you free rolls.)

Jayesh Patel is adamant that he is not that sort of retailer. He has been an agent for donkey’s years in Abbey Wood, South East London, and does £20-£25K a week for PP (a recently much-increased turnover as others around him have gone).

But he recently ran out of till roll and had to borrow half a dozen rolls from another retailer. When he rang to tell PP he was told he should still have 19 rolls, because it is monitored. PP sent him more, but also sent an email telling him that if he rings for more he will be charged £25.

He is outraged that anyone could suggest he uses the till rolls for anything other than PP and wanted to know how someone worked out he should still have 19 rolls. PP’s Peter Brooker replies: “Our stock counting system takes into account usage by individual terminal, not by shop, so even if the volume fluctuates widely, new stocks are sent out as needed at each shop.

“We have no reason to believe it could be inaccurate, not least because it is part of the same system that records the terminal’s transactions and generates the daily direct debit amounts, commissions payable and other payments to or from the retailer. Each box of 30 rolls should contain enough paper to print between 5,000 and 6,000 receipts. If we had missed more than 3,000 transactions (represented by the 19 missing rolls), there would have been a massive discrepancy in payments to and from the retailer.”

I asked Jayesh if the box could have been tampered with or didn’t contain the requisite number in the first place, but he didn’t know. From now on, he is getting staff to note the date the roll is changed.
