Single-Entry Bookkeeping for Sole Proprietors

Single-entry bookkeeping is a simple and cost-efficient method for managing bookkeeping when your business activity is small-scale. In this article, we’ll explain what single-entry bookkeeping means, who can use it, and how it works in practice.

What Is Single-Entry Bookkeeping?

Single-entry bookkeeping means that financial transactions are recorded only once—either as an income or expense—on a cash basis. This means that you record transactions when money actually moves, not when an invoice is issued or received.

Who Is Eligible for Single-Entry Bookkeeping?

Single-entry bookkeeping is allowed under certain conditions. You can use it if:

  • You operate as a sole proprietor (not as a limited company)
  • You have no employees
  • Your fiscal year is the calendar year (Jan 1–Dec 31)
  • Your annual turnover is under €200,000
  • You only sell goods or services within Finland

If these conditions are met, single-entry bookkeeping is an excellent choice.

What Information Must Be Recorded?

Single-entry bookkeeping requires the following information to be recorded:

  • Income and expenses (based on payment date)
  • Value-added tax (if you’re VAT registered)
  • Fixed assets (e.g., tools, machinery, vehicles)
  • Bank account and any cash balance
  • Any private withdrawals or contributions

Bookkeeping can be automated by using our service designed for entrepreneurs.

Summary of Benefits and Challenges

Benefits:

  • Simplicity: less information to record
  • Cost-effective: can be done without an accountant
  • Clear cash flow tracking

Challenges:

  • Only suitable for small-scale businesses
  • Less detailed financial overview than double-entry bookkeeping
  • Limited to sales within Finland

Conclusion

If you operate on a small scale without employees and your annual turnover stays under €200,000, single-entry bookkeeping is a light and functional solution. It allows you to focus on running your business without a heavy administrative burden.
