RedHen Labs vs SellerMate.ai
SellerMate.ai starts cheap: a free plan, and Pro at $29 a month ($20 billed annually) with a monthly credit allowance. Its Unlimited plan is $150 a month ($105 billed annually) "Or 1.5% of monthly ad spend, whichever is higher" — so above $10,000 a month in ad spend, the percentage sets the bill: $375 at $25,000.
Its AI agent asks first — "Nothing executes until you click to confirm" — while Pro's "Bids, budgets & bulk edits on autopilot." RedHen Labs is $129 a month flat, and every automation starts in an approval queue.
Cheap until the percentage takes over
SellerMate's Pro plan is $29 a month, but Unlimited is $150 a month or 1.5% of monthly ad spend, whichever is higher. Above $10,000 a month the percentage decides: $375 at $25,000, $750 at $50,000. RedHen Labs stays at $129.
Two answers to who decides
SellerMate's AI agent asks first — "Nothing executes until you click to confirm" — while its Pro plan lists "Bids, budgets & bulk edits on autopilot." RedHen Labs uses one rule for both: changes wait for your approval unless you switch a specific automation to run on its own.
When SellerMate is the better pick
If a credit-based AI agent at $29 a month covers what you need, SellerMate's Pro plan costs far less than ours.

Why we don't charge more
We could charge more. We don't, and it isn't because this is a lighter product — it's because it's a focused one. We built the things an Amazon seller actually touches every week and left out the twenty modules that pad a suite. A focused product costs less to build and less to run, so it can cost less to buy.
The other reason is simpler. By the time a seller has paid referral fees, fulfillment, storage, returns, and advertising, a lot of hands have already been in the till — and then an agency wants a percentage of sales and a tool wants a percentage of spend. The person who designed the product, paid for the inventory, and carries every bit of the risk ends up with the thinnest slice of it. We decided not to be one more toll on that road. $129 is a number we can hold at any account size, which means growing your business never costs you more to keep using ours.
