Some background:
I am a garment designer.
I am currently subcontracting garment manufacture.
My subcontractor holds raw materials (purchased and supplied by me).
I may in the near future manufacture garments in house but will also use a subcontractor.
The subcontractor currently supplies me with finished garments ready for me to pack and sell.
The subcontractor gives me price breaks as follows:
garments in price group A
unit price £45 1-10 products.
unit price £40 11-24 products.
garments in price group B
unit price £55 1-10 products.
unit price £50 11-24 products.
There are more price groups similarly structured.
My sales channels are online (shopify) and wholesale.
How best to plan and implement ERPNext in my use case. Any guidance much appreciated.
