How to switch
Connecting Refunzo doesn't require disconnecting Seller Investigators first. Both read your account through Amazon's own authorization flow, so you can run Refunzo's free reconciliation alongside your existing provider, compare what each one finds, and decide which cases go where before you commit to anything.
