Accounting errors will happen from time to time， but many common accounting mistakes can be avoided with proper planning and preparation. Here are the top seven accounting mistakes that should be paid more attention to. （ 1 ）Not knowing your true cash balance： Due to things like automatic payments and bank charges， money that appears in your cash drawer and your checking account may already be spent. （ 2 ）Mistaking profits for cash： When you have a lot of credit sales， your company can post big profits without seeing any cash. （ 3 ）Paying bills too soon： If your vendors give you thirty days to pay them， take it. Unless you get a discount for paying early， paying your bills only when they’re dueimproves your company’s cash flow. （ 4 ）Avoiding book -keeping tasks： Not recording and posting transactions regularly leaves you with a mountain of book-keeping to deal with in the end. （ 5 ）Paying accidental dividends： Every time a corporation owner takes money out of his business， it counts as a dividend. That can lead to a bigger personal income-tax bill. （ 6 ）Not keeping personal finances separate from business： Mixing up business and personal money can cause bookkeeping and legal problems. （ 7 ）Setting prices too low： Know your costs before you set product or service prices， or you run the risk of losing money on every sale. A simple break-even analysis can help you set prices at a profitable level. With a lot of credit sales， your company may have no cash at hand. 蓝细菌凯恩斯主义货币政策是要通过对（）的调节来调节利率，再通过利率的变动影响总需求贴现率。准备率。货币供给量。货币需求量。主分量变换（K-L变换）网站管理员面对垃圾内容该如何应对？（）删除垃圾内容。严控机器发帖行为。对站内的异常时行监控。进行技术操作，降低相似度。
