[justinmaniac23]

Hey guys so I'm starting a brand but i'm using print on demand not printfull or anything just a local nearby me. so basically my stock is all blanco hoodies t shirts etc. now i was wondering how i link all blanco t shirts (stock) to all my products that show up on the website with designs. so i sell like a t shirt with a pig that's on my website and than my stock for all t shirts (blancos) go from 100 to 99 . and let says. my stock for t shirts = 0 than all t shirts are sold out. now i need to know how i can link this stock to all my products for my print on demand. if someone please could explain me how to do this, I would really appreciate that. if you have a youtube video explaining this that would be even better. in advance thank you.
