44
Test of control
• “thinking like a crook”
• the holes in the controls:
• nobody seeks to verify data with external sources.
![Page 45: 1 Chapter 10 acquisition and expenditure cycle including audit of accounts payable and inventory existence.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649d305503460f94a0909c/html5/thumbnails/45.jpg)
