Accounting Period
An accounting period is a set amount of time during which financial transactions can be recorded and made. It helps make sure that reports are correct and stops people from making changes without permission after the books are closed.
In ERPNext, the Accounting Period limits the transactions that can be submitted (like Sales Invoices, Journal Entries, Stock Entries, etc.) to a certain range of dates. After the period is over, you can't send in any more selected transactions.
1. What is the significance of the accounting period?
When a transaction is submitted, it changes the ledger and affects financial reports.
If users can post entries outside of the time they are supposed to, it can mess up audits, tax filings, and financial closures.
Accounting periods help keep financial data safe and reports honest, especially at the end of the year or after audits.
1. How to Make an Accounting Period

Click on Accounts > Accounting Period
To make a new period, click on New.
Type in a name for the time period, like Q1 2025.
Set the period's start and end dates.
Add the types of transactions you want to control to the child table (for example, a sales invoice or a journal entry).
Check the "Closed" box next to each type of transaction you want to limit after the period ends.
Press Save and Submit.

1.1 What does the "Closed" choice do?
The Closed checkbox in the child table tells the program whether a type of transaction will be limited after the accounting period ends.
If this box is checked, users will not be able to submit that transaction after the time period ends.
The transaction type stays open even after the period ends if this box is not checked.
Note: If you try to submit a "closed" transaction after the period is over, ERPNext will give you a validation error.
Important Notes
After the Accounting Period ends, no user, even those with the "Role Allowed to Set Frozen Accounts & Edit Frozen Entries" role, can submit restricted transactions.
This is a strict rule to keep people honest with their money and ready for an audit.
