Here are some helpful tips for streamlining bookkeeping for your business:

1. Have separate bank accounts for business and personal expenses
2. Make deposits to business accounts no more than once per week
3. Pay all bills once a month through Quickbooks so that all of your expenses are categorized automatically
4. Once a week, record work-related mileage and any other business-related expenses and file for end-of-year
5. Have a bookkeeper do this for you, or at least look over your work for errors and missing information on a regular basis
6. Have a bookkeeper reconcile and estimate tax payments
7. At end of year, have a bookkeeper finalize your accounting and prepare 1099s for subcontractors, when applicable
8. Submit your books to a CPA to complete taxes

One hint for automatically tracking business expenses is to make all purchases for the business on a debit or credit account that is exclusive to the business. This way, the account can be categorized and directly reconciled through bookkeeping software.
