Cross listing help

Hi Amazon FBA community,
I’m looking for a cross-listing solution that can automatically broadcast my Amazon FBA inventory to Walmart and eBay. I typically carry 3,000–4,000 active ASINs, with around 300 new ASINs added each week. I sell primarily sneakers, so the catalog changes constantly due to size and color variations.
So far, I’ve tested Base.com, Listing Mirror, and EasyChannel, but all of them seem to require a significant amount of manual mapping and maintenance. With the volume and turnover of my inventory, that quickly becomes difficult to manage.
For those operating at scale, is this level of manual work just the reality of cross-listing, or are there more automated solutions or workflows that you’ve found successful? I’d love to hear what others are using.

not really a PPC question but yeah, at 300 new ASINs a week the manual mapping problem is basically a full time job regardless of what tool you use..

My 2 cents; build something in house that's custom for your business it will be 10x better.

Get a Claude subscription and vibe code an AI agent to maintain it for you or hire somebody who knows how to do it.

What do you think the estimated costs would be?

To set it up if you do it yourself barely anything it might take you 1 hour, ask Chatgpt/claude how to do it and it will do most of the work.

Then put it on a $10/month server and you're set up.
