Setting up the cost of your stock dresses can be done with ease, @wendy-thesilvers.
If you haven't turned on stock tracking on your settings, follow these steps:
Go to the Gear icon and select Account and Settings.
Select Sales.
Click the Edit icon in the Products and Services section.
Turn on Show Product/Service column on sales forms.
Turn on both Track quantity and price/rate and Track stock quantity on hand.
Select Save and then Done.
Now you can add your stock dresses. I'd recommend reaching out to your accountant to help you in categorizing them. If you don't have one, you can visit the ProAdvisor site to find an accountant.
Here's how to add your products name and category:
Go to Sales, then Products and Services.
Select New or Add a product or service. Then select Stock.
Add a Name, SKU, or category for what you're tracking.
Select the category from the Category ▼ drop-down.
Add your product’s Initial quantity on hand. Then enter when you started tracking that quantity in the As of date field.
