I am an eBay lister and researcher. I list items manually and using listing tools.
I do order fulfillment jobs and customer service.
These are the tools I used in listing and researching items:
Zik Analytics - for researching Hot selling products
AutoDS and DSM Tools - for listing items
SkuGrid - for updating item's price and stocks availability
Onlinejobs.ph "ID Proof" indicates if "they are who they say they are".
It DOES NOT indicate skill level.
ID Proof scores are 0 - 99 with 99 being the best. It is calculated based on dozens of data points.
It's intended to help employers know who they're talking to is real, and not a fake identity.
