What is QuickBooks Negative Inventory?

Negative Inventory in QuickBooks

QuickBooks Negative Inventory is a situation where the quantity of inventory recorded in QuickBooks shows a negative value. This occurs when more items are sold or used than the available stock. It is a discrepancy that needs to be addressed to maintain accurate inventory records and avoid potential issues in financial reporting and inventory management. It is basically an error that arises when the amount of the sale and the purchase do not match. Let us see how it works.

When the User Sells the Product that is Recorded in the Company File

  1. You buy products using the Items Tab on the item receipt bill, credit card, bill or check and crediting cash, A/P, or Credit Card Payable.
  2. Then you can sell the products from the inventory. However, the user can never sell more than the stock items.
  3. The sale transaction records two transactions.
  • Editing A/R and crediting sales: Sale/ Receivable transactions.
  • Crediting Inventory and debiting COGS: Inventory/ COGS transactions.
  1. Run the P&L and expense report that shows the invoices and sale receipts.
  2. Run B/S reports that show item receipts, checks, bills, and credit card charges.

When the User Sells Products that have NOT been Entered in the Company File

  • Saves the invoice data for the Receivable/ Sales transactions as expected.
  • For the products that are not on hand, QuickBooks assumes them as:
    1. Same as the average cost of the other item on hand.
    2. The cost of the item from the item list.
  • QuickBooks COGS/Inventory transaction using the assumed price.
  • To correct the difference, QuickBooks does not assume the cost of the next purchase and then the purchase transaction will be recorded as QuickBooks inventory adjustment.

What Triggers the Negative Inventory?

There are a bunch of triggers that can cause a Negative Inventory Adjustment account. Read the list below to understand the issue in depth.

  • The damaged data forced you to constantly rebuild the file to bring the B/S in balanced form.
  • An imbalance of the cash-basis Balance Sheet might also be a reason for the occurrence of the error.
  • The amounts of COGS and Profit could be incorrect.
  • The data of the Balance Sheet Inventory Account might not be correct.
  • You could have entered the wrong Vendor Reports.
  • The system might encounter an overflow error. 
  • Error: Itemhistupdateengine.cpp — LVL_ERROR–Error: Verify item history Target average cost mismatch error
  • Error: Verify Account Balance failed. Calc bal = 0.00, List bal = *overflow*
  • Error: LVL_ERROR–Error: Verify Account: Invalid balance. The amount of overflow has occurred. Rcrd = 99.
  • Error: Itemhistupdateengine.cpp — LVL_ERROR–Error: Verify Item History: Bad target COGS for Item.

Issues While Using QuickBooks Negative Inventory

Below are a few issues a user might face while using the QuickBooks Negative Inventory. Let us discuss them pointwise.

New Inventory Product With No Average Cost:

  • If, the user has created a new inventory product, with the Product Cost but does not add an initial QOH/ VOH. QuickBooks will assume that the product has no average cost. Instead of a bill, the first transaction of the item would be used as an invoice. This would force the sale towards negative inventory. The cost price of the item would be different from your purchase price. The difference can cause an adjustment on the P&L report.
  • If, the user has created a new inventory but without the Product Cost. Hence when the user would sell the item, it won’t have any inventory. QuickBooks does not have any data or information regarding the average cost, therefore it would calculate the mean cost of $0.00. As a result, the data will distort the data of your inventory and COGS. The data is not accurate until the user has established the average price with a credit card, bill, check, or Value On Hand/ Adjust Qty.

Negative Inventory Cause Errors in Supplier Reports:

The COGS/ Inventory is normal on the invoice. If the user would sell the out-of-stock inventory, it may cause the QuickBooks Inventory Adjustment to the next bill by adjusting the COGS/ Inventory transaction.

Inventory Assemblies Shows Incorrect COGS on Job Costing Reports

Let’s say you have an insufficient quantity in stock. Later you have created an assembly that would cost different from the average cost. This will adjust the Inventory of the build transaction- COGS, which generally includes the invoice. The build transaction would not further allow entering the details related to customers.
