The Month End Close Process: Step-By-Step
For many business owners and finance teams, the end of the month isn’t just about flipping a calendar page — it’s about reconciling, reviewing, and resetting the books. This is called the month end close, and it ensures financial records are complete, accurate, and ready for informed decision-making. Done well, the month end close process keeps you compliant, speeds up reporting, and provides a clear view of your company’s financial health.
Below, we’ll explain what the month end close process is, why it’s crucial, what it includes, and how to complete it step-by-step — plus how AP automation tools like Flex can help make it faster and more reliable.
What is the Month End Close?
The month end close is the process of reviewing, reconciling, and finalizing all accounting records for the month. This involves:
- Ensuring all transactions are recorded in the correct accounts
- Reconciling account balances
- Reviewing supporting documentation for accuracy
- Making necessary adjustments or accruals
- Generating preliminary financial statements
Once complete, the books are “closed” for that month, preventing further changes and providing a finalized record for financial analysis or audits.

- Accuracy: Ensures financial statements reflect true business performance.
- Compliance: Helps meet tax and regulatory requirements.
- Efficiency: Prevents bottlenecks during quarterly or year-end closing.
- Decision-making: Provides timely, reliable financial data for strategic planning.
- Fraud prevention: Helps detect unusual activity or errors early.
