H2 (Second Half)
H2 (Second Half) is July through December — the back half of the year and, for most Amazon sellers, the profit engine: Prime Day season, back-to-school, the Q4 crescendo, and every promotional event the marketplace builds around consumer spending.
What is H2?
H2 (Second Half) is July through December — the back half of the year and, for most Amazon sellers, the profit engine: Prime Day season, back-to-school, the Q4 crescendo, and every promotional event the marketplace builds around consumer spending.
It’s also where the year’s risk concentrates. The same months that generate the majority of revenue generate the majority of stockouts, storage-surcharge hangovers, and advertising overspends — because demand arrives faster than operations can react, and the cost of every planning miss gets multiplied by seasonal volume.
The H2 shape (and what each phase demands)
July–August: event season with Prime Day as the anchor — demand spikes reward prepared inventory and punish optimistic stock positioning. September–October: the calm before — Q4 inbound must be in the network by early autumn (late orders arrive after the demand they were meant to serve; freight rates climb through the season). November–December: peak velocity — Black Friday week, Cyber Monday, the holiday push — where conversion is easy and the scarce resources are stock, ad budget, and attention. January is technically H1, but H2’s decisions own it: the stock you carry into the new year was sized (or mis-sized) during the autumn buying window.
Managing H2 without drama
Three disciplines. Inventory: size Q4 orders off forecast scenarios rather than hope, keep heroes deep and long-tail thin, and pre-commit to a post-peak plan (the January deal calendar for anything that didn’t sell through). Spend: budget ad spend by event with daily caps and explicit TACoS tolerance — peak auctions get expensive by design, and unmanaged budgets vanish into bidding wars; pre-decide which products harvest and which build. Operations: staffing and supplier capacity locked by October (everyone’s busy; the vendors who planned get served first), and monitoring cadence raised — daily during event weeks, because that’s when something always happens. The sellers who enjoy H2 are the ones who spent H1 making it boring.
In practice
A brand’s H2 plan reads like a campaign calendar: freight booked in July against Q4 orders, inbound complete by October, ad budgets allocated per event with daily caps, staffing locked, and — the line most sellers forget — a January clearance plan written in November (which SKUs get deal slots if sell-through trails). The season executes close to plan: no stockouts on heroes, no storage hangover, and January opens with a ranked, reviewed catalogue instead of a warehouse of December’s optimism.
How Harpy Media helps
Peak-season planning — event calendars, inbound deadlines, spend caps, and post-peak exits — starts in our client work in May or June, because H2 is manufactured in H1.
H2 FAQ
What is H2?
Second Half — July through December; the peak revenue period with Prime Day, Black Friday, and the Q4 holiday season.
Why is H2 risky for Amazon sellers?
Because seasonal volume amplifies planning errors — late inventory, uncapped spend, and overstock hangovers all cost more at peak scale.
How should sellers prepare for H2?
Book freight and complete inbound early (by October), allocate ad spend per event with caps, lock staffing/suppliers, and write the January clearance plan in advance.
