Allowing inventory levels to fall below zero can lead to unintended consequences, including inflated cost of goods sold (COGS) or variance account figures.

To sell an item before it’s physically in stock, create a sales order. Once you receive the inventory, convert the sales order into an invoice.

 NOTE: Sage 50 doesn’t track inventory COGS when inventory is below zero.

1. Select Setup, Settings, Inventory & Services, then Options.
2. Add a check mark next to Allow inventory levels to go below zero for items without serial numbers.
3. Select OK to save the setting.
