Brand Ungating

Hi I want to get approved for brand to sell and I saw that I need to provide the invoice of 10 units from this brand or the distributor. My question is, Would Amazon accept the invoice of 10 units but not bought on the same day in one order, but bought in multiple orders to reach 10 units in total? Also do you need to have 10 units of the same product or I can have 10 units of the same brand but different products?
