Certified Bookkeeper (CB) — How to Get Certified & Why It Matters
If you're serious about a bookkeeping career, certification is one of the highest-ROI investments you can make. It costs a few hundred dollars and a few months of study — but it can add $10,000-$20,000/year to your income and unlock premium clients who won't hire uncertified bookkeepers.
The Two Major Bookkeeper Certifications
In the United States, two organizations offer recognized bookkeeper certifications:
| Feature | AIPB — Certified Bookkeeper (CB) | NACPB — Certified Public Bookkeeper (CPB) |
|---|---|---|
| Organization | American Institute of Professional Bookkeepers | National Association of Certified Public Bookkeepers |
| Requirements | 2 years experience + pass exam | Education + experience + pass exams |
| Exam Format | 4-part exam (proctored) | 4 separate certification exams |
| Cost | ~$574 (members) / ~$874 (non-members) | ~$500 total |
| Study Time | 3-6 months self-study | 3-6 months self-study |
| Continuing Ed | 60 hours every 3 years | 24 hours per year |
| Best For | Employed bookkeepers wanting credibility | Self-employed bookkeepers wanting the "Public" designation |
Which One Should You Choose?
Honestly? Either one works. The market doesn't strongly favor one over the other. Here's a quick decision guide:
- Choose AIPB (CB) if you already have 2+ years of experience and want the most recognized credential
- Choose NACPB (CPB) if you want to start your own bookkeeping firm (the "Public" designation signals client-facing work)
- Choose both if you want to maximize credibility (overkill for most people, but it exists)
What the AIPB Certified Bookkeeper Exam Covers
The AIPB CB exam tests practical bookkeeping knowledge across four parts:
Part 1: Adjusting Entries

Study Plan: Pass the CB Exam in 90 Days
| Weeks | Focus | Hours/Week |
|---|---|---|
| 1-3 | Part 1: Adjusting Entries — review concepts, practice problems | 5-7 |
| 4-6 | Part 2: Error Correction & Payroll — focus on payroll calculations | 5-7 |
| 7-9 | Part 3: Depreciation & Inventory — memorize methods, practice | 5-7 |

Study tip: The AIPB sells a workbook for each part. They're worth every penny — the actual exam questions closely mirror the workbook problems.
Beyond Certification: The Advisory Path
Certification establishes your credibility, but it's not the ceiling. The real money is in advisory services. Here's the progression:
- Certified Bookkeeper — Credibility + premium rates ($40-60/hr)
- Advisory Bookkeeper — Cash flow forecasting, budgets, KPI dashboards ($75-150/hr)
- Fractional CFO — Full strategic financial leadership ($150-300/hr)
Certification is step one. The skills you build studying for the exam (adjusting entries, internal controls, financial analysis) are the exact foundation you need for advisory work.
