# QBO Error: Attempt to update QBO Item has failed with the following error: 400 - BadRequest ValidationException was thrown. 6200 - The account period has closed. Account Period Closed

## Problem

The **400 Bad Request Error** is an HTTP response status code that indicates that the server was unable to process the request sent by the client due to invalid syntax. In other words, something in the batch you are exporting from ServiceTitan to QBO is out of alignment. In the case of the error "The account period has closed. Account Period Closed" this means that you have set a date in your QuickBooks Online that does not allow transactions from posting before that date so an error has occurred.

## Solution
