How a commercial packaging brand doubled Amazon weekly sales while cutting TACOS nearly in half
A commercial packaging brand on Amazon was running ads on products that could not fully convert because core SKUs were out of stock or constrained. In 7 days, after restoring inventory and pushing advertising aggressively, weekly sales nearly doubled from $2,218 to $4,186, and TACOS dropped from 31.26% to 19.46%. The lever was treating inventory and advertising as one coordinated move, not two separate workstreams.
01The challenge
A commercial packaging brand on Amazon was spending on ads but not getting proportional returns. The TACOS was running at 31.26% on $2,218 in weekly sales, a signal that ad spend was working harder than it should need to for the revenue it was generating.
The root cause was inventory. Key items were out of stock or constrained, which meant ad spend was driving traffic to listings that could not convert at full rate. Every click that landed on an unavailable or low-inventory product was wasted budget. The ads were not the problem. The ads were paying the cost of the inventory problem.
02The approach: The In-Stock Ad Push
The In-Stock Ad Push runs two moves in parallel, not in sequence. Get the core SKUs back in stock and push advertising aggressively at the same moment inventory is restored. A gradual ad ramp after restocking leaves velocity on the table. The push has to happen at the same time as the fix.
Restore inventory on core SKUs
Worked with the brand to prioritize getting the main items back in stock. For a commercial packaging brand, the SKUs that drive the highest order frequency are also the ones most likely to go out of stock under demand. Restoring those first creates the foundation for everything else. Ads on out-of-stock listings do not convert; ads on in-stock listings with demand behind them do.
Push advertising aggressively at the moment of restock
The advertising team executed an immediate push on ad spend as soon as inventory was restored, not a gradual ramp. The logic is straightforward: when a core SKU comes back in stock after a period of unavailability, organic rank has typically dropped and visibility has declined. An aggressive ad push at restock accelerates the rank recovery and captures demand that has been building during the stockout period.
03The results
In the 7-day period after the coordinated inventory and ad push, weekly sales went from $2,218 to $4,186, an 88.7% increase. TACOS dropped from 31.26% to 19.46%, a reduction of 11.8 percentage points. Incremental weekly revenue: $1,968.
Why it worked: inventory and advertising are not separate workstreams on Amazon. They are the same workstream. Ad spend on constrained inventory drives TACOS up and revenue down because clicks cannot convert. Restoring inventory and pushing ads simultaneously collapsed TACOS and nearly doubled revenue in a single week. The brand entered June on pace for its strongest sales month in recent history.
04FAQ
Why would fixing inventory reduce TACOS on Amazon?
TACOS is ad spend divided by total revenue. When core SKUs are out of stock or constrained, ads still run and spend still accumulates, but conversion rates drop because customers cannot buy. Lower conversion means lower revenue per ad dollar spent, which drives TACOS up. Restoring inventory lets the same ad spend generate more conversions, which increases revenue and brings TACOS down. On this account, TACOS dropped from 31.26% to 19.46% in 7 days after restocking.
What is the In-Stock Ad Push?
A two-move framework executed in parallel: (1) restore inventory on the highest-priority SKUs; (2) push advertising aggressively at the exact moment inventory is restored. A gradual ad ramp after restock leaves rank recovery velocity on the table. The push must coincide with the restock to capture demand that accumulated during the stockout period.
How quickly can Amazon sales recover after a stockout?
In this case, the combined inventory and ad push produced an 88.7% increase in weekly sales within 7 days. Recovery speed depends on how strong the organic rank was before the stockout, how long the stockout lasted, and how aggressively ads are pushed at restock. Brands with strong pre-stockout rank and high search volume on their core terms tend to recover fastest.
Does this apply to other categories beyond packaging?
Yes. The pattern applies to any account where stockouts are causing TACOS inflation. Categories with high reorder rates, like consumables, supplies, and commodities, are especially susceptible because customers who cannot buy once tend to substitute competitors rather than wait. The same In-Stock Ad Push framework applies.
