Fix Overflow Error in QuickBooks Desktop

Overflow Error in QuickBooks

The overflow error in QuickBooks arises when a numerical value exceeds the software’s handling capacity, often due to data entry mistakes or huge numbers. Imagine fitting a gallon of water into a pint-sized cup; inevitably, some water will overflow. Similarly, when a number is too large for the allocated space in QuickBooks, it triggers an overflow error.

When you run the Verify Data utility in QuickBooks and see the error message “An overflow error has occurred. One of your accounts has exceeded the maximum value allowed,” it indicates a specific issue with your data. Additionally, when you open your Chart of Accounts or run a report, you might notice that one or more balance sheet accounts or amount columns display “overflow” instead of numerical values.  

Understanding how to fix this error is essential for maintaining accurate and manageable financial records. In this article, we’ll walk you through the steps to identify the causes of overflow errors, pinpoint where they occur in your accounts, and provide practical solutions to resolve these issues effectively.

Reasons why Overflow Occurs in QuickBooks Desktop

  1. When an account balance or field surpasses $9,999,999,999,999.99, QuickBooks flags it as an overflow error.
  2. Copying data from Excel spreadsheets with incompatible formats can trigger overflow errors upon pasting into QuickBooks.
  3. Altering large quantities within Group Items can generate overflow indicators next to their component items.
  4. Instances where an inventory item’s value exceeds its quantity, such as having a quantity of 1 and a value of $18,000,000, can result in overflow errors.
  5. Damaged transactions within your company data file may also contribute to overflow errors.

The Solutions to Fix QuickBooks Overflow Error

To achieve optimal outcomes, following the solutions in the specified sequence is advisable.

Note: Before delving into any troubleshooting steps to resolve overflow errors in QuickBooks Desktop (2019, 2018), it’s essential to ensure that your computer meets the system requirements outlined by QuickBooks. Make sure to focus on  Regional Settings, Disk Space, and available RAM.

Solution 1: Rebuild your Data File

  1. Access the File menu and select Utilities, then choose Rebuild Data.
  2. If prompted with a warning message advising you to back up your company file, click OK to proceed.

Note: If your computer shows a message suggesting that QuickBooks is unresponsive, don’t worry. As long as you can still move your mouse cursor, let the process continue until it’s finished.

  1. Once you receive the message stating “Rebuild is complete,” click OK to acknowledge it.

Solution 3: A Group Item is Overflowing

  1. Reset the Group Item Quantity to zero, then move to the next field.
  2. Re-enter the accurate Group Item quantity.

Solution 4: Just one Item is Overflowing

  1. If the item is new, remove it from the Item list, then create it again.
  2. If it’s an existing item: 
  • Conduct an audit of the item to identify and rectify the transaction causing the overflow.
  • Example: For a bill with an amount of $1,000,000 and a quantity of 1 instead of 1,000,000, correct the transaction to maintain accurate average cost. 
  • If you’re unable to locate such a transaction, utilize an Adjust Quantity/Value on Hand document to correct the average cost.

Solution 5: The Balance or Other Field of an Account is Too Large

  1. Initiate basic troubleshooting steps.
  2. Create a portable company file and restore it to establish a new working file.
  3. Inspect your Chart of Accounts:
  • Access Chart of Accounts from the Lists menu.
  • Identify any account with a balance exceeding 10,000,000,000,000.
  • Adjust the balance to prevent it from reaching this threshold.
  1. Review Memorized Reports
  • If overflow appears in a memorized report, rerun it from the Reports Menu.
  • If the issue persists, delete and recreate the Memorized Report.
  1. Scrutinize all lists for fields containing amounts or totals
  • Utilize Lists and  Add/Edit Multiple List Entries.
  • Customize Columns to display relevant fields (e.g., Credit Limit, Cost, Price).
  • Identify and rectify any instances of overflow.
  • Conduct a thorough check across all lists
  • In newer QuickBooks versions, click on Edit and Search to look for “overflow”. Initially, search for list elements and then transactions. Continuously run verifies after modifying amounts in the company file until the overflow error no longer arises.

Solution 6: Damaged Transactions

  1. Run multiple reports (e.g., Financial Statements, Custom Transaction Detail, Sales by Customer, Sales by Item, etc.) until you encounter overflow.
  2. Utilize QuickZoom to navigate to the transaction level for the overflow. Rectify the identified transactions by making necessary corrections.
