How a Wholesale Distribution Brand Grew Amazon Sales 14.2% While TACoS Improved
A large wholesale distribution brand on Amazon Mexico was already healthy, running a substantial weekly sales base, but carrying waste and untapped demand. In one week, total sales grew from MXN 270,135 to MXN 308,474 (up 14.2%) while TACoS improved from 6.7% to 5.8% and ACoS held flat. Growth came at a lower cost, not a higher one.
01The challenge
A large wholesale distribution brand on Amazon Mexico was already running a substantial weekly sales base: MXN 270,135. The account was not broken. It was healthy in the way established accounts often are, which hides two things: waste that has accumulated quietly, and demand nobody has gone looking for yet.
The account was carrying a 6.7% TACoS, inside target but with room. Some ad spend was inefficient, and there was traffic the existing campaign structure was not capturing at all.
02The approach: The Three-Lever Efficient Scale
The Three-Lever Efficient Scale is three moves run together, not in sequence: stop the waste, feed the winners, and go find the demand nothing is capturing yet.
Reduce wasted ad spend
Cut spend on underperforming targets across the account, freeing budget that was not converting into budget that could be redeployed.
Boost the proven performers
Increased budget on the campaigns and targets already converting well, so the freed spend compounded existing strength rather than chasing something new and unproven.
Launch new campaigns for missing traffic
Identified and launched campaigns specifically to capture demand no existing campaign was reaching, adding a new source of growth rather than just reallocating the same pool.
03The results
One week later, total sales rose to MXN 308,474, up 14.2% (roughly MXN 38,339 more), while TACoS improved from 6.7% to 5.8% and ACoS held flat. The account grew and got more efficient in the same week.
Why it worked: on a large existing base, efficient growth compounds hard. Adding meaningful top-line without eroding margin, on an account already running below its 12% TACoS target, leaves clean room to reinvest and push further.
04FAQ
Can a large, already-healthy Amazon account still find 14% more growth in a week?
Yes, when the growth comes from three separate levers run together: cutting waste, feeding proven performers, and launching new campaigns for demand nothing was capturing yet. This wholesale distribution account grew total sales 14.2% in a week while TACoS improved, not worsened.
What is the Three-Lever Efficient Scale?
A framework for accounts that are healthy but not fully optimized: reduce wasted ad spend, boost budget on already-proven performers, and launch new campaigns to capture missing traffic, all three run at the same time rather than sequentially.
Does scaling an Amazon account always raise TACoS?
No. On this account, total sales grew 14.2% while TACoS improved from 6.7% to 5.8% and ACoS held flat, because the growth came from cutting waste and capturing previously-missed demand, not from spending more broadly.
How much room does an account have if it is already below its TACoS target?
This account was already running under its 12% TACoS target and still found 14.2% weekly sales growth with TACoS improving further, to 5.8%. Headroom below a target does not mean an account is optimized, it means there is room to find out.
