I'm having trouble with were I place the expense of my goods for my business. I do not have an inventory. When a customer orders, I then procure it at wholesale.

Do you do anything to it before you sell it to the customer?  For example, do you buy materials and then make something?

We order it and then assemble it at the customers home.  No alterations to the product.

Either enter it under Supplies or as Other Misc Exp.

Go to Business tab- then Continue
Business Income and Expenses - Click the Start or Update button

Then click EDIT by the business name and the next screen should be a list of  topics,
Business Profile, Income, Inventory/Cost of Goods Sold, Expenses, Assets, and Final Details last.

Under Business Expenses, Click Start or Update by Other common business expenses.  You should see the list of expenses and amounts you entered.
Then click the start or update button by the expense you want to add or edit.

Supplies is the 13th item under Expenses - Click the Start or Update button
Other Miscellaneous Expenses is the 16th item under Expenses - Click the Start or Update button

Thanks

Additional question.  Were do we place an investment loss?

The investment in the business or stock sales?

For business loss you just enter your income and expenses.  If your expenses are more you will have a Net Loss on schedule C.  You don't enter the loss, it is calculated and goes to 1040 line 12.

For investments you should get a 1099B for sales.
Enter a 1099B  under
Personal
Personal Income
Then scroll down to Investment Income,
Then Stocks, Mutual Funds, Bonds, Other - click Start or Update

Thank you so very, very, much.
