Evidence And Context
Why this wedge exists right now
SellerShock is not guessing at a timeless SaaS idea. It is a fast response to a concrete seller problem with public evidence, updated Amazon planning tools, and visible operator frustration.
Sell on Amazon
Amazon's own fee-estimation workflow
Amazon explicitly points sellers to fee and revenue estimation tools, which validates this planning behavior even if SellerShock stays lightweight.

DD+7 Cash Gap Planner
How much cash gets trapped before Amazon releases it?
This estimate assumes you are still fronting inventory and ads while payouts wait on delivery plus the reserve window.
High risk
Days to cash
9 days
Delivery lag plus reserve timing. About 105 orders a day are flowing through that delay.
Revenue tied up
$36,000
Top-line revenue sitting in the delayed payout window.
Cash exposure
$9,000
The inventory and ad dollars you are fronting before the payout lands.
Estimated reserve gap
$0.00
Buffer runway: 18 days at your current spend pace.
Recommended next move
Your current buffer is likely too thin for the payout lag. Reduce exposure, tighten ad spend, and raise price on weak-margin SKUs first.
Estimated contribution margin after COGS and ads: 3.0%.

Pure surcharge drag before you change price, costs, or ads.

What that drag looks like at your current monthly unit pace.
New fee load

Cost-cut target per unit

Founder Note
This exists because “figure it out later” is how small seller problems become real cash problems
The current Amazon seller pain is unusually concrete: payout timing changed, a new surcharge is landing, and many operators do not need another generic ecommerce newsletter. They need a fast answer about working capital and repricing. SellerShock is intentionally narrow because narrow is what gets shipped, used, and paid for first.
