How do marketplaces verify store revenue before a sale?
Most marketplaces verify little or nothing: they accept seller screenshots, or at best a Google Analytics connection - and analytics counts visits, which bots can fake, not money. Real verification connects to the store's order system read-only and reconciles claimed revenue against actual orders. If a marketplace cannot show order-level proof, treat the numbers as unverified.
The three levels of proof
Level one is a screenshot, which anyone can edit in five minutes. Level two is an analytics screen-share, which shows traffic but not revenue. Level three is order-level reconciliation against the platform's own API - the only level where the number and the money are the same thing.
Questions to ask any marketplace
Does verification read the order ledger or just analytics? Is the connection read-only and logged? Does a human review flags, or is it a rubber stamp? Is unverified data labeled as unverified? A trustworthy marketplace answers all four without flinching.
How Kairos does it
Eight automated checks against read-only Shopify order data, ad-spend reconciliation where the store runs Google Ads, and a human review of every flag before the memo is published. Listings that fail get rejected, and the rejection count is public on the scoreboard.
