Why your BFCM prep needs to start in August

Ask most brand managers when they start preparing for Black Friday and Cyber Monday, and the honest answer tends to be September. Some say October. A few will admit it is the week before.

The problem is that by September, some of the most important BFCM preparation decisions are already off the table. Inventory is what it is. Deal submissions have closed. Advertising structures that take weeks to test have not been built. September is not peak season preparation. It is peak season damage limitation.

Research consistently shows that brands which begin their Amazon Black Friday strategy 10 to 12 weeks before the event capture significantly more traffic and avoid the stockouts and missed opportunities that hold back late starters. For BFCM, that puts meaningful preparation firmly in August.

Why BFCM preparation cannot wait until Q4

Peak season performance on Amazon is largely determined by three things: whether you have stock, whether your deals get top placement, and whether your advertising is efficient from the moment the event opens. All three have lead times that push meaningful preparation into August at the latest.

Inventory

Amazon's fulfilment centres have intake cutoff windows before major events, and building a credible demand forecast for every deal ASIN takes time. If you’re creating those forecasts in October, you’re working with compressed timelines that leave no room to correct for errors. Inventory decisions for BFCM need to be made in August, not October.

Deal submissions

Amazon's deals team works to fixed submission windows, and the best placements go to brands that are organised early. Getting a deal on the BFCM deals page, rather than buried in category results, requires a submission that’s in on time and meets Amazon's requirements. That process starts in summer.

Advertising

Amazon's algorithm rewards early advertising engagement. Campaigns need four to six weeks to build relevance, accumulate data, and position efficiently for the moment competition peaks. Brands that activate campaigns in November are playing catch-up from the first day. The brands that win on BFCM don’t start preparing in Q4. The brands that start in Q4 are the ones playing catch-up.

What a well-run BFCM preparation timeline looks like

Effective Amazon Black Friday strategy is a pipeline, not a checklist. Each stage feeds the next:

This isn’t a rigid formula. The specifics vary by brand, category, and marketplace mix. But the principle holds: if any of those August and September activities are happening in October, you’re already behind.

The benefit of early preparation

Brands that prepare early don’t just perform better at BFCM. They also perform better at October Prime, which sits directly before it on the calendar. October Prime is both a commercial moment in its own right and a dress rehearsal for November. The forecasting, advertising, and operational processes you run there directly inform your BFCM readiness.

Brands that take October Prime seriously, even with modest commercial expectations, tend to enter BFCM in significantly better shape than those that treat it as an afterthought.

Why preparation timing shapes the whole season

Brands that prepare early don’t just perform better at BFCM, they also perform better at October Prime, which sits directly before it on the calendar. The forecasting, advertising, and operational processes you run there directly inform your BFCM readiness, making it both a commercial moment in its own right and a dress rehearsal for November.

The cost of leaving this late is real. The brands that consistently outperform aren’t the ones with the biggest catalogues or the deepest discounts. They’re the ones that selected the right ASINs early, secured strong deal placements, and had advertising in place that could perform from the first hour. Early event hours on Black Friday drive a disproportionate share of total revenue, and products that build momentum early carry that ranking advantage through the rest of the event.

Where to start

The most valuable actions to take, regardless of where you are in the year:

• Map your deal ASIN selection and identify inventory requirements early
• Confirm your deal submission calendar and set hard internal deadlines ahead of Amazon's windows
• Audit your advertising account structure and build event-specific campaigns
• Optimise listings for the search terms that spike during BFCM before the event window opens
• Document contingency plans for deal suppressions and stock shortfalls before they happen

Early BFCM preparation is not about working harder. It is about making the decisions that have the biggest commercial impact while there is still time to make them properly.
