Most business owners I meet aren't bad with money. They're busy. The books slide in March, then it's summer, and now it's fall and the shoebox is full. The good news: catching up is a process, and the order you do it in matters.

Step 1: Pull every statement first

Download bank and credit card statements for every account the business touched, January through last month. Don't categorize anything yet. Just get them all in one folder. Missing statements are the number one reason a catch-up stalls.

Step 2: Separate business from personal

If business and personal spending are mixed in one account, go through and mark which is which. From here on, use one account for the business only. That single change makes every future month easier.

Step 3: Categorize one month at a time, oldest first

Start with January and finish it before moving on. Use the same few categories every time: income, supplies, software, advertising, vehicle, phone, contract labor, fees. Consistency beats perfection.

Step 4: Find the records for the big items

  • Receipts or invoices for equipment and large purchases
  • Mileage: a log with dates, miles and the business reason
  • Payments to contractors, with their W-9s
  • Loan statements, so payments aren't counted as expenses

Step 5: Reconcile

Reconciling means your books match the bank's ending balance each month. If they don't match, something is missing or doubled. This is the step people skip, and it's the one that catches the mistakes.

Step 6: Keep it from happening again

Put 20 minutes on your calendar every week to categorize transactions. Twenty minutes a week is a lot easier than 20 hours in January.

When to hand it off

If you're more than six months behind, have multiple accounts, payroll or sales tax, or you just keep putting it off, a bookkeeping catch-up is usually faster and costs less than doing it under deadline pressure. We'll tell you up front what it would take.

There's no such thing. We've caught up businesses that were more than a year behind. It just takes the statements and some patience.
