How to Perform Period End Processing in Sage 100 Purchase Order

An "accounting close," also known as "month-end close" or "period close," is a process that businesses undergo to finalize their accounts at the end of a financial period. This could be at the end of a month, quarter, or year.

During the accounting close, all financial transactions for the period are reconciled and recorded. This includes everything from sales revenue and operational expenses to payroll and inventory adjustments.

Once all transactions are accounted for, financial statements like the balance sheet, income statement, and cash flow statement can be prepared. These statements provide a comprehensive overview of the company's financial health at the end of the period, informing decision-making for the next one.

The accounting close process is a crucial part of a company's financial management and ensures accuracy and compliance with accounting standards. It provides valuable insights into a business's financial performance, aids in strategic planning, and is essential for transparency with stakeholders, investors, and regulatory bodies.
