Thank you for contacting us with your query, Mindy. I understand how important it is to set up your financials correctly, especially as a new company using QuickBooks Online (QBO). Let me assist you with your concern regarding posting vendor invoices with cost codes.

In QBO, when posting vendor invoices that need to reflect in both the COGS account and specific cost codes, it's crucial to correctly set up your Products/Services and Chart of Accounts.

Ensure that every item listed in the Products/Services, associated with the COGS (Cost of Goods Sold) account, also has a specific class or location designated for tracking purposes. This class or location should match your designated cost codes. Consequently, whenever you record an invoice with a particular Product/Service, QuickBooks will automatically document it in the appropriate COGS account and monitor it using the correct cost code via the class or location attribute.

To fix this, check your Products and Services settings and ensure each item is linked to the correct COGS account. Then, activate and use class or location tracking from Account and Settings under the Advanced tab. Assign these classes or locations according to your cost codes.

When creating the vendor bill, select the appropriate Product/Service item and choose the corresponding class or location.
