Comparison
Bookkeeper vs. Controller
Quick answer
A bookkeeper records day-to-day financial transactions — invoices, receipts, payroll entries, and bank reconciliations — ensuring the books are accurate and current. A controller oversees the entire accounting function, produces financial statements, implements internal controls, manages the accounting team, and ensures compliance with GAAP or other standards. Bookkeepers maintain the records; controllers manage the system, the team, and the reporting.

Key differences
When to choose Bookkeeper
- Your business is small (under $1M revenue) and needs accurate day-to-day transaction recording
- You want clean books for tax preparation without paying controller-level rates
- Your accounting needs are routine: invoicing, expense categorization, and monthly reconciliation
- You have a CPA or accountant who reviews the books periodically — bookkeeping is the execution layer
- You are just starting out and managing cash flow visibility is the primary financial need
When to choose Controller
- Your business has crossed $1–3M in revenue and needs reliable monthly financial statements
- You have a small accounting team that needs management and process oversight
- You are preparing for an audit, raising capital, or require GAAP-compliant financials
- Internal controls are weak and you need someone to design and enforce them
- You need the accounting function to scale with the business rather than just record transactions
Which Should You Choose?
Most businesses start with bookkeeping and add controller-level oversight as they grow. A bookkeeper keeps the records accurate and current — critical for any business. A controller transforms those records into insights, enforces financial discipline, and ensures the accounting function is scalable. Consider a fractional controller as a cost-effective intermediate step before a full-time hire.
Typical cost
Monthly bookkeeping (sole proprietor)
₩80,000–₩350,000/month
Priced in revenue bands, so higher revenue means a higher band. Usually quoted before VAT. App-based services can charge less with narrower service.
Monthly bookkeeping (corporation)
₩150,000–₩400,000+/month
Corporations pay more because their return needs financial statements and a tax adjustment schedule (세무조정계산서).
Annual tax adjustment (조정료)
₩250,000–₩3,000,000+
A yearly fee, usually billed separately from the monthly fee. Small individual filers sit at the low end, larger corporations at the high end.
Consultation
₩20,000–₩150,000 per session
Online platforms are at the low end and traditional offices at the high end. Many offices credit it against later work.
