You're so Right About Organizing Your Books by: Lisa McGrimmon
Beverly, you are so right about the importance of having a book keeping strategy in place right off the bat. It's very tempting to ignore that aspect of business management, especially when you're first starting out.
I have also had the not-so-fun task of going back over old receipts and records trying to figure things out. It's a lot easier to track expenses properly as you go.
The other good piece of advice I was given when I first started working for myself was to get in the habit of saving some of my income each month so I'd have what I needed to cover what I owed in taxes each year. Since tax laws vary widely from country to country, and they also can vary based on your level of income, the amount each person will need to save will be very individual. It's smart to talk to someone in your area who knows about tax laws and self employment to get a sense of whether you will likely need to pay taxes at the end of the year and how much you'll need to cover that expense.
