Upgrading to Pro or selling as Individual?

[jcdev]

Hello, does anyone has an experience selling as individual amazon seller? and then going back to pro in 2019?

I 've got a 1 year old amazon individual seller account, but I never sold through it myself. It was a pro account, but then was downgraded on the second month.

I am selling popular high-ranked goods with lots of reviews. Since individual accounts cannot get Buy Box, does it affect sales?? I am concerned that individual accounts may be selling too slow.

I don't want to be stuck with a lot of unsold inventory, but on the other hand I don't have any documents for this account, so I will have to draw them from scratch (it is a stealth one).

What can you guys recommend? Thx.
