Can still remember when our company went to computerised invoicing. The staff could not get their heads round it and did not trust the computer to do it right. The old method of handwritten invoicing and pricing was a known method and the staff just could not get their fingers working properly. They could not understand when they typed in a 9 digit number for a head gasket- the invoice came out for a door panel at 5 times the price. They did not understand operator error and that they had made the error.

Within 6 months and they had corrected the operator and were getting it right- Till the day when the computer failed for the first time. Then it was "Emergency" hand written invoicing and they had forgotten how to write- and how to add up.

All that has changed now with the computers going down at least twice a week and we keep a stock of a months worth of blank invoices for the situation that we have been told will never occur.

And as to doing a stock check with the "Old" Cardex system- That would be impossible nowadays.
