How to write off inventory?

I appreciate your posting here in the Community, @Bender_1227. Let me share some tips and guidance on writing off an inventory.

We can record this as a promotional sample that has no value. First, we can create an expense to track. Here's how:

1. Go to the Gear icon, then under the Your Company section, click on Charts of Accounts.
2. Select New, and from the Account Type dropdown, select Expenses.
3. On the Detail type dropdown, choose Advertising/Promotional.
4. Enter the name you prefer.
5. Hit Save and Close.

You can follow the next step in creating an invoice for the item on this link: Write off inventory items given as promotional samples in QuickBooks Online.

If you are using QuickBooks Desktop and need to adjust your inventory quantity, detailed instructions can be found by following the link.

Why would you use Schedule D?  If you truly have obsolete inventory, just expense it to COGS in Part III of Schedule C if this is a sole proprietorship (SP).  There's no dollar limit on that.  If this is anything other than a SP, expense it to COGS on the business return.

Did you even read your customer's post?  There was no mention of promotional items.
