What’s the best Slowest way to sell on Amazon just enough to skirt by?

Thanks for your help. The e-commerce markets still seem to be in turmoil with their processes as they continually seek to fine tune how they want to do things. With that thought I maybe want to sell a $14 product on Amazon and am thinking that I only want to skirt by and sell just enough to keep the system going. Is FBA going to let me do that well if I just send in inventory little by little? I hear Shopify and the others are currently a mess too so I’m kind of looking for the cleanest dirty shirt as they all seem to be in transitionary cycles still as the internet/e-commerce evolves.

I think I just want to do enough to skirt by while hopefully as time moves forward all the online marketplaces and host’ can better clean up their direction. They all seem to not mind running over the sellers currently. They are fishing for big fish it seems at the other sellers expense.

I might start out with about 1000 sellable units(these are smaller items, maybe 5 x 5 x 1.5″ dimensions) and won’t be in a rush. I’m thinking Amazon will try to make me move them fast or charge me storage. As a side note I was thinking about already renting a local small storage unit anyways to keep inventory in and just send it in to Amazon little by little. That storage unit may already cost me about $45/mth locally anyways. If I was going to do that it would seem that I might as well pay Amazon’s storage fees instead and just deal with it down the road if things get really bad. Is Amazon storage fees that much per month? Have any ideas on that concept?

I basically want to take my time while I would continually fine tune my own business efforts and strategies. I might as well pay Amazon’s storage fees instead of a local storage unit. I think my initial inventory size might be something similar to a 4 x 4′ pallet maybe 3 ft tall.

What other ideas does annyoje have for me? I am ok with losing money on the first while of my business efforts. I’m planning on bringing the inventory from China and eventually moving it to Amazon obviously. It’s quite strange the kickback I’ve received from USA suppliers, the last one said they had staffing issues..

Thanks for thoughts.
