Early feedback

Sellers are switching

"I was on Sumtracker Replenish at $149/month and still getting 10-minute sync delays. Syncstocky updates in seconds and costs half as much. It wasn't even a hard decision."

James R.

Shopify + Amazon seller, UK

"The AI forecasting gives me actual reasoning, not just a number. It told me exactly why my Q4 products were trending early and how much to reorder. Sumtracker never came close to this."

Priya S.

Multi-channel seller, Canada

"Setup took 8 minutes. All channels synced, products imported, first webhook fired. I've tried three other tools including Sumtracker. This is the fastest I've ever been up and running."

Carlos M.

eBay + Shopify seller, US
