SME Year-End Closing: Deadlines, Internal Controls, and Common Errors

Year-end closing is a crucial step for any business, especially for small and medium-sized enterprises (SMEs). It provides an accurate picture of the company’s financial health, ensures compliance with legal obligations, and prepares for the future. In this article, we guide you through the key steps to a successful year-end closing while avoiding common mistakes.

Why Year-End Closing Is Crucial for Your SME

Year-end closing is more than just an administrative formality. It plays a key role in the management and sustainability of your business. Here’s why:

  • Compliance with legal obligations: In Switzerland, SMEs must comply with the Swiss Code of Obligations regarding accounting and financial reporting (source: Code des obligations: obligations comptables).
  • Performance analysis: Closing allows you to measure your company’s profitability and identify areas for improvement.
  • Preparing for the future: The data from the closing serves as a basis for financial forecasts and budgeting.
  • Relationships with third parties: Financial statements are often required by banks, investors, or business partners to assess the company’s financial strength.

Properly Planning Your Year-End Closing: Timeline and Key Steps

A successful year-end closing is based on rigorous planning. Here are the key steps to follow:

1. Prepare a Detailed Timeline

  • Identify the legal deadlines for filing accounts (source: Year-End Closing: Important Dates).
  • Create a backward schedule, considering the time needed for each step.

2. Gather the Necessary Documents

  • Customer and supplier invoices
  • Bank statements
  • Ongoing contracts
  • Inventory lists

3. Prepare a Preliminary Balance Sheet

  • Check the accuracy of accounting entries.
  • Identify anomalies or inconsistencies.

4. Finalize Closing Entries

  • Record depreciation, provisions, and adjustments.
  • Ensure all entries are justified.

Managing Sensitive Entries: Provisions and Adjustments

Provisions and adjustments are key elements of year-end closing. Poor management can distort your financial results.

Provisions

Provisions anticipate probable future expenses. They must be recorded if:

  • The event causing the expense occurred before closing.
  • The amount can be reliably estimated.

Examples of common provisions:

Type of ProvisionExample
Provision for litigationOngoing legal proceedings
Provision for warrantiesRepairs under warranty
Provision for taxesIncome taxes payable

Adjustments

Adjustments ensure expenses and income are recorded in the correct accounting period. For example:

  • Prepaid expenses: Costs paid in 2023 for a service in 2024.
  • Accrued income: Income from 2023 not yet invoiced.

Essential Documents for a Successful Year-End Closing

An effective year-end closing relies on complete and organized documentation. Here are the essential documents:

  • Balance sheet: Shows the company’s financial position at year-end.
  • Income statement: Details income and expenses to assess performance.
  • General ledger: Lists all accounting entries.
  • Trial balance: Checks the balance of accounts.
  • Appendices: Provide additional information (details of provisions, off-balance-sheet commitments, etc.).

Internal Controls: Methods to Ensure Quality Closing

Strong internal controls are essential to ensure the reliability of financial data. Here are some best practices:

1. Segregation of Duties

  • Ensure responsibilities are well distributed among accounting team members.

2. Cross-Checks

  • Compare bank statements with accounting entries.
  • Reconcile customer and supplier accounts.

3. Use of Digital Tools

  • Choose efficient accounting software to automate repetitive tasks.
