Your ACoS Is Fine. Your Margins Are Not.
TACoS Optimization from Marketplace Valet governs Amazon advertising spend against total channel revenue — not ACoS alone — to protect bottom-line profitability for established brands. Founded in 2016 and led by Will Land, Laura Land, and Justin Boggs, the agency has delivered outcomes including doubled sales alongside reduced advertising costs for national consumer brands. Results vary.
Enter your monthly numbers. The calculator returns your real TACoS — what advertising actually costs against total channel revenue.
Enter your numbers above to see where your TACoS stands.
Indicative ranges only. Healthy TACoS varies by category, contribution margin, and channel maturity. The free audit produces a tailored benchmark.
ACoS Measures a Campaign. TACoS Measures a Business.
ACoS tells you the cost of one attributed sale. It says nothing about whether you would have made that sale anyway — or whether your ads are funding margin for an unauthorized seller who stole your Buy Box.
TACoS — Total Advertising Cost of Sale — measures spend against total channel revenue. It is the only number that shows whether advertising is growing your business or cannibalizing it.
Marketplace Valet manages every campaign to TACoS as the governing standard. Not ACoS. Not ROAS. TACoS.
One Metric. Every Campaign. One Standard.
How the program is built.
TACoS is tracked daily through the 3P360 client data dashboard alongside account health and listing integrity. TACoS governs whether reach is producing revenue or just activity.
If a campaign is driving spend to a listing with an unauthorized seller in the Buy Box, we catch it. If sponsored spend is eating organic rank, we act before it becomes a margin problem. Advertising and account management operate under the same P&L standard. One program. One metric.
The Standard Comes From Running a Real P&L.
Not a dashboard. An actual business.
Will Land and Laura Land scaled a consumer brand to over 10 million direct-to-consumer orders — managing ad spend against landed cost and contribution margin, not reported ROAS.
Justin Boggs, Chief Revenue Officer and Forbes Business Development Council contributor, has published Amazon advertising strategy specifically on optimizing spend for revenue performance.
One national home fragrance brand cut advertising costs and doubled sales through this program. Results vary by brand, category, and investment level.
This Is Not for Every Brand.
Brands That Manage to the Dashboard and Call It Growth
Brands that want ACoS targets hit and reports sent are not a fit. The program isn’t built to optimize toward a campaign-level metric — it’s built to govern the whole P&L.
Brands That Approve Individual Bids
Brands that want to override execution or approve individual bids make P&L-level management impossible. If you want a vendor to manage campaigns to a metric, we are not it.
If your margins are shrinking while your dashboard looks clean, this program is built for that problem.
Find Out Where the Spend Is Leaking.
The free Amazon audit identifies where your advertising diverges from TACoS discipline and what it is costing your total channel. Diagnostic only. Not a sales call.
