1) You are prepared to file your taxes in January
When you keep track of your income and expenses during the year using a bookkeeping software program such as QuickBooks, Quicken, Mint, or one of the many other good bookkeeping programs, when the year is over, you will have all of your financial information in proper order. Then all you need to do is print a profit-and-loss statement to send to your accountant, or take the information off of the profit-and-loss statement to file your own tax return using TurboTax or a similar program.
2) You have enough money to pay your bills on time
By using a good financial management program such as QuickBooks, you will be able to easily run a report that details the money owed to you by your customers. By staying on top of the money owed to you, and following up with your customers, you will have improved cash flow. Also by knowing how much money is owed to you, and by estimating when you can expect to receive payment based upon past customer payment history, you can better predict your cash flow. Knowing this, if you see that you are going to be low on funds, you have the option of paying your suppliers 
later, reducing your purchases, or making a big effort to increase sales.
3) You have more time to do other things
Many tasks take up more time when you are disorganized, as you need to hunt for things that an organized person would easily find. When you are organized, you are able to accomplish more in less time, providing you with the extra time you need to take on new projects or take some time off.
4) You have a lower level of stress
If you are not organized, you feel additional stress and you start to feel overwhelmed as you can’t find things easily, work piles up, and you are not sure which task to tackle first. The added stress of being disorganized often leads to mistakes, poor follow-up, missed deadlines, and negative interactions with customers, colleagues, co-workers, family, and friends. Being organized is a proven stress reducer. When you get organized, you feel positive about yourself, and it feels as if a load has been removed from your shoulders.
5) You look good
When you are organized, people notice. They see that you are on time, meet deadlines, and respond timely to requests. That leaves a very favorable impression.
