COGS/reordering bulk purchase, individual sale

Then do you have to adjust the inventory manually?

Hi aboard2123,

In addition to MikeinBC's answer, you'll have to switch the unit of measure option in the inventory item.

Here are the steps:

1. Click Lists located at the top.
2. Choose Item List, and find the item.
3. Double-click the item to open.
4. Under Unit of Measure, select the U/M Set from the drop-down list.
5. Click OK.

Then, manually adjust the inventory by following the steps:

1. On the Item List page, right-click on the item.
2. Choose Adjust Quantity/Value On Hand.
3. Select the Adjustment Type, Adjustment Date and Adjustment Account.
4. Click the Find & Select Items button.
5. Click Save and Close.
