Economic crime

Your post makes very little sense. By government, do you mean the actual government or just the management of whatever company you work for?

If you're talking about the actual government and you say this is the first time you've ever done this I call bullshit because every government department, no matter how small will have either an internal audit team or access to external auditors who would be able to sort this out very quickly and easily.

Anyway, most likely scenario is that they're purchasing off contract or they're teeming and lading, using money designated for one supplier to pay off another and so on. Either sounds implausible though because only a proper fuckwit would perpetrate that kind of fraud to hire more employees, they'd only ever do it for personal gain and to pocket the spare cash.

Explain yourself better, preferably in English this time.

Jam it back in, in the dark.
