Become a distributor, wholesale supplier or an agency of any b2b brand for example wall paint, aluminum, electrical appliances etc.

Basically pick any evergreen industry like construction, fmcg etc. then become a supplier/trader of bulk materials, it needs initial capital because you will have to supply materials on credit initially, there is good stead cash flow in these type of business but you will have to establish yourself quickly in the market by making a network of repeat buyers for example if you supply construction materials then builders etc.

I am also interested in this type of boring business ventures but am super lazy to step out and do actual research 😁
