I've been talking to Vince Masi, a Londis retailer of some standing, who trades at Lyneham in Wiltshire. He has developed a software program that he says takes the strain out of the chore of cashing up at the end of the day.

"I call it the Easy Way to Cash Up program," he says, "and it works for stores with one to four tills, with or without scanning."

Vince worked for the multiples for years and had examined the various permutations. "There's usually one book for cash, one for paid-out, one for summaries, and so on. This program does it all. Enter the figure for the amount taken and the rest more or less takes care of itself."

He has had it on test at a big store in Bracknell, run by fellow Londis retailers Arjan and Lalita Mehr, who are very happy with the results. Vince is thinking of a price tag of about £89 + VAT. If you are interested, give him a call on 01249 890210.
