The foundation is separate accounts. Open a business checking account and get a business credit card. Run all business transactions through these accounts and keep personal purchases on your personal accounts. When everything flows through dedicated business accounts, categorization becomes simple because every transaction is business by default.

Start with your bank. Most banks offer free or low-cost business checking accounts. You’ll need your EIN or Social Security number if you’re a sole proprietor, plus basic business documentation. Once the account is open, route all business income there. Customer payments, client checks, and revenue deposits go into the business account only.

Get a business credit card and use it exclusively for business expenses. Materials, supplies, software subscriptions, and business travel all go on the business card. This creates a clean audit trail and makes expense tracking straightforward. The statement itself becomes your documentation of what was spent on the business.

When you need to use personal funds for a business expense, record it as an owner contribution or reimburse yourself from the business later. The expense is still deductible, but you need to track it properly in your books. In QuickBooks, use an equity account like Owner Investment to record personal funds used for business purposes. Don’t just ignore these transactions or they’ll create problems at tax time.

Stop using the business account for personal purchases. No groceries, no Amazon orders for the house, no personal subscriptions. Every non-business transaction you run through business accounts creates extra work categorizing and reconciling. It also makes your financial statements less useful because they include spending that has nothing to do with the business.

If your accounts are currently mixed, you have two options. You can clean up the existing accounts by going through and categorizing everything properly. Or you can draw a line in the sand and start fresh with new dedicated accounts. Starting fresh is often faster than trying to untangle months of mixed transactions. Catch-up bookkeeping can handle the cleanup if you need help sorting through the history.

For contractors and tradespeople, separation matters even more because job costing requires knowing exactly what was spent on each project. When materials bought with a personal card never make it into the books, your job profitability numbers are wrong. You can’t make good decisions about which work to pursue if you don’t know which jobs actually made money.

The discipline of keeping accounts separate pays off every month when reconciliation takes minutes instead of hours. It pays off at tax time when your CPA can work from clean records instead of asking questions about random transactions. And it pays off whenever you want to know how your business is actually performing. If you’re looking for bookkeeping services in American Fork to help maintain that separation going forward, the first step is always getting those accounts set up correctly.
