5 Bookkeeping Mistakes Contractors Make (And How to Avoid Them)

Running a contracting business is hard enough without messy books slowing you down. Here are the five most common bookkeeping mistakes we see contractors make — and how to fix them.

1. Mixing Personal and Business Finances
   This is the number one mistake. Always keep a separate business bank account and credit card. Mixing finances makes bookkeeping a nightmare and can create serious tax problems.
2. Not Tracking Job Costs Properly
   Every job should have its own income and expense tracking. Without this, you have no idea which jobs are actually profitable and which ones are costing you money.
3. Falling Behind on Reconciliation
   Skipping monthly bank reconciliation leads to errors that compound over time. Reconcile every account every month — no exceptions.
4. Missing Receipts and Expenses
   Every business expense is a potential tax deduction. Use a simple system — even just a folder on your phone — to capture receipts immediately.
5. Waiting Until Tax Season to Organize Everything
   By then it’s too late to fix problems. Clean books all year means no stress in April and no missed deductions.

The good news? All of these problems are completely avoidable with the right bookkeeper in your corner. That’s exactly what we do at Profit & Found.
