Amazon PPC tools with a flat fee
A flat fee stays the same when ad spend rises. A percent-of-spend fee does not. Six tools below publish a flat starting price. M19, Scale Insights, Teikametrics and BidX also sell a plan that adds a percentage. That plan is named in the price column so it is not mistaken for the flat one.
