it's almost like the perfect storm that is how this longtime educator describes why her elementary school got mixed up in a false billing scam it was just a crazy hectic time of year with expansion new building three locations new secretaries so what an invoice for just over six hundred dollars came in from a known vendor it was just paid at that point just seeing the name of the company which is one that we had been buying from and a small invoice for you know less than a thousand it really got overlooked this school was not alone postal inspectors say robert armstrong sent out more than 77,000 false invoices the former school administrator who had lost his job knew exactly how schools operated it appeared that he knew when to send the invoices so that they would get mixed in with the summer ordering so that the invoices would get passed through the system a little bit easier than they would if there was more of a closer eye looking at the invoices like saying februari there were more than 650,000 dollars in losses from over 1,000 schools postal inspectors say the most important lesson is for all businesses to have a specified series of checks and balances Debbie says her school has the right system but the bill came at a challenging time now she knows better never be too busy or too much in a hurry to not take the time to really look at something that's going to cost you money
