You already know what sells. The problem is that every reorder ties up cash in stock you hope will move, and every new colourway is a bet placed months in advance.

Move your proven sellers onto on-demand production and the maths changes: no bulk buy, no dead stock, no warehouse. You keep the retail-grade blanks and the print quality your customers already expect, and you free the capital to put behind marketing, new drops and the things that actually grow the brand.
