DIY Bookkeeping: 7 Mistakes That Cost You Time (and Money)

Doing your own bookkeeping can work, especially when your business is simple and you’re consistent. The problem is that most DIY bookkeeping fails for one reason: it’s treated like an “extra task,” not a system. Then you lose weekends, stress about taxes, and still don’t trust your numbers. You’re not alone if you started DIY with good intentions and ended up behind.
 

Quick Answer

• 7 common DIY mistakes

• How to fix them without becoming a bookkeeper

• A simple weekly/monthly routine

• When outsourcing is the smarter move
   

The Real Problem

DIY isn’t hard. DIY without structure is hard.
 

Why It Matters

• Cleanup later costs more (in time or money)

• Inaccurate reports lead to bad decisions

• Tax time becomes stressful and expensive
   

Simple Framework

10-Min Weekly + 60-Min Monthly

• Weekly: review + quick checks

• Monthly: reconcile + close + review
   

7 DIY Mistakes + Fixes

1. No monthly close deadline → Fix: Close by the 10th

2. Skipping reconciliations → Fix: Reconcile every account monthly

3. Mixing personal + business → Fix: separate + reimburse properly

4. Overusing “Uncategorized” → Fix: clean weekly, not yearly

5. Not tracking contractors → Fix: tag + keep W-9s

6. Not matching processor payouts → Fix: reconcile sales reports

7. Never reviewing reports → Fix: monthly P&L review with 3 questions:

   • What went up?

   • What went down?

   • Does this match reality?
      

Tools + Templates

• Monthly close checklist
