Business Expenses

Do you know how to keep track of your business expenses? I am not an accountant, but here's what I've learned: 1. Open a seperate checking account and credit card account in your business's name, this is for ease of accounting. 2. Keep receipts and track the income and expenses, I do it monthly. Total the columns and see if you made or lost money for that month. 3. Remember to send an estimated earnings check to the IRS quarterly, if you made more than you spend.
