The mistakes we see most often aren’t complicated. They’re simple habits that seem harmless in the moment but create expensive problems down the road.

Mixing personal and business expenses is the most common one by far. Using one card for everything, running personal purchases through the business account, or paying business expenses from a personal account. It makes reconciliation a mess, weakens your liability protection if you’re an LLC, and forces your accountant to spend hours sorting through transactions at year end. Open a dedicated business checking account and credit card, and use them exclusively for business.

Falling behind on reconciliation is a close second. A lot of business owners plan to “catch up later” and suddenly they’re six months behind. By that point, you can’t remember what half the transactions were for. Bank feeds pile up with uncategorized entries. Duplicate transactions sneak in. What would have taken an hour per month now takes days to untangle, and the cost of catch-up bookkeeping is always more than staying current would have been.

Misclassifying expenses sounds minor but it distorts your financial picture. Putting a laptop under office supplies, categorizing a contractor payment as wages, or lumping everything into “miscellaneous” means your profit and loss statement tells you nothing useful. You can’t spot trends, compare periods, or make informed decisions when your categories are wrong. It also creates issues at tax time because certain expenses are treated differently on your return.

Not tracking contractor payments throughout the year is another big one. You pay various contractors and vendors, and then January rolls around and you’re scrambling to figure out who got paid over $600 and needs a 1099. If those payments weren’t coded properly all year, you’re digging through bank statements and guessing.

Ignoring accounts receivable happens a lot with service businesses. You send an invoice and assume it’ll get paid. Without a system to track outstanding invoices and follow up on late payments, cash flow suffers and revenue slips through the cracks.

Finally, trying to do it all yourself when you don’t have the time or knowledge usually leads to several of these mistakes happening at once. Working with a bookkeeper in Franklin who understands your business prevents small errors from becoming big, costly problems. The goal is accurate books that actually help you run your business, not just check a box.
