I am a dropshipper. What should I fill on Line 8300 of my T2125 (Statement of Business or Professional Activities)?

Line 8300 is asking me to report my Opening Inventory. I am a dropshipper, and I don't hold any inventory. I buy and ship directly to my customers. What would I report on this line?

Self-employed

If you don't have inventory, then you don't need to fill in the inventory section of the form.
