Last night, Oliver worked very late to prepare the financial books of a local construction company. The business had an official government audit the next morning, and everything needed to be completely perfect. Oliver checked the annual budget carefully to compare the numbers and verify the company's financial health. First, he reviewed the total income from international investments and real estate sales during the year. Next, he examined the long list of corporate expenses, including office supplies, worker salaries, and new machines. There was a major problem because a large amount of money disappeared from the official database. Oliver felt incredibly stressed, but he started checking every paper receipt inside the old office cabinets. After three long hours, he discovered a massive, unrecorded payment for the local community taxes. He corrected the balance sheet immediately, saved his client from a legal penalty, and finished his night with a peaceful smile.
