7 Bookkeeping Mistakes NJ Small Business Owners Make

October 2, 20256 min read

After cleaning up books for dozens of NJ businesses, I’ve seen the same mistakes repeatedly.

1. Mixing Personal and Business Expenses

The most common and most damaging. Open dedicated business accounts. Period.

2. Not Reconciling Monthly

Errors accumulate silently without monthly reconciliation.

3. Categorizing Everything as Miscellaneous

If 30% of expenses are miscellaneous, you have no visibility.

4. Not Tracking Cash Transactions

Unreported cash income is an audit trigger. Unclaimed cash expenses are lost deductions.

5. Ignoring Accounts Receivable

Aging invoices represent revenue at risk.

6. Not Keeping Receipts

The IRS requires substantiation. Use a receipt scanning app.

7. DIY When You Shouldn’t

If books are consistently behind, it’s time to bring in help.
