Most Amazon ads tools and agencies bill a percentage of ad spend, so their fee grows with your budget. Here is what flat-fee software costs and when each mod…

Flat-fee tools such as AIAdKing, Sellerboard and the fixed tiers of Scale Insights charge the same monthly price whatever you spend on ads. Percentage-of-spend pricing, used by most agencies and by Perpetua, Teikametrics, Adbrew and Quartile above their entry tiers, typically adds 2 to 5 percent of monthly ad spend, so a seller spending $20,000 a month pays $400 to $1,000 a month on top of any base fee. Flat pricing wins as soon as your ad budget is meaningful; percentage pricing only makes sense when a human team is actively managing the account.

## FAQ

Q: Why do Amazon ads agencies charge a percentage of spend?
A: Because their cost is human hours, and larger accounts need more of them. The model is reasonable for a managed service; it is much harder to justify for software, where the cost of running one more account is close to zero.

Q: Is flat-fee PPC software worse for large accounts?
A: No. The automation does the same analysis on 50 campaigns as on 5. What changes on a large account is the need for strategy and creative, which is a person, not a pricing model.

Q: Does AIAdKing have a minimum ad spend?
A: No minimum and no maximum. The flat monthly fee is the same at any ad spend, and the free trial gives the full product for its duration with no card required.

Q: What does AIAdKing cost compared with a percentage-of-spend tool?
A: One flat price per month, listed in USD on the pricing page, with everything included. A 3%-of-spend tool costs the same only if you spend under roughly $1,000 a month on ads; above that the flat fee is cheaper every month.
