Black Friday Is Won in the Two Weeks Before It

Use the fortnight to close decisions, not create another checklist

Black Friday falls on 27 November 2026 and Cyber Monday on 30 November. For a retailer starting on the Friday, 13–26 November is the fourteen-day preparation window. Earlier offers need earlier checkpoints; the title does not mean every supplier problem can be solved within a fortnight.

Give the event one agreed product scope, demand window and stock timestamp. Core holds the forward sales, intake and closing assumptions; Core Plus provides the inventory and allocation context. The output should be a decision to release, revise or hold a specific offer, with an owner for every unresolved condition. A completed checklist cannot substitute for usable stock or authorised pricing.

Days fourteen to ten: reconcile cover line by line

Compare the event forecast with held stock, existing reservations, unavailable units and confirmed incoming quantities for the same SKU and location. Separate what is usable today from what is expected before launch. A style-level stock total can hide a missing size even when the aggregate supply looks comfortable.

Core’s MFP/WSSI keeps the event and the following weeks on one stock path. Core Plus supports the matching store and size review. State which stock definition each calculation uses and when it was taken. Do not include a future optional repeat as launch supply, or count a warehouse unit in more than one destination proposal.

Test one size run before signing off the total

The worked Everyday knit has 24 small, twelve medium and 24 large units usable at the destination, sixty overall. A confirmed receipt expected to become usable on 25 November adds twelve, sixteen and twelve. Held stock plus that on-time receipt is 36/28/36, a hundred units against event demand of sixteen/32/sixteen, or 64 in total.

The total exceeds demand, but medium is four units below its own requirement. Choose a four-unit medium closing buffer, and the matching top-up requirement becomes eight: 32 expected sales plus four closing less 28 supply. A proposed eight-unit movement from a source holding thirty medium units retains 22 there, above its twelve-unit reserve. If accepted and usable in time, destination supply becomes 36/36/36, or 108, and expected closing becomes twenty/four/twenty, or 44. All quantities are independent planning assumptions.

Days nine to five: prove arrival and isolate optional intake

The 25 November receipt is useful only if the stock becomes usable before the 27 November demand starts. Confirm what its date represents, whether the size quantities are intact and whether receiving time is included. A supplier dispatch date or an expected transport milestone is not the same as stock ready for the offer.

Keep the forty confirmed incoming units visible while reviewing a separate optional 48-unit repeat proposed for 4 December. Holding that optional repeat for a post-event decision does not cancel the confirmed launch receipt. Core keeps the later demand and intake assumptions connected; Core Plus lets the stock owner review existing incoming supply before adding another allocation. Any commercial order change still requires its applicable agreement and authority.

Days four to one: check the offer that customers can actually buy

Confirm the eligible product, size, channel, price, start and end dates, discount depth and any overlapping offer. A Core planning version can record an accepted price assumption, but the relevant operational system must confirm its execution. Match the customer-facing availability to the exact variant and current transaction record; Google’s product-data guidance likewise requires availability to agree with the landing offer.

For the knit, recheck the proposed eight medium units against the current source and receiving date before release. The 108-unit position is conditional, not physical stock already at the store. Keep reservations, transit and receipt status distinct. This article does not claim that Core Plus automatically updates every advertising platform, executes the price change or authorises the transfer.

Make the late-arrival fallback explicit before launch

If the sixteen incoming medium units become usable only after the event, the original twelve held plus the proposed eight provide twenty ready medium units against 32 expected sales. That leaves a twelve-unit service gap even though small and large each still have 36. Extra units in those other sizes do not fill the missing medium requirement.

The source would retain 22 after the first proposal, but twelve are protected by its stated reserve. Only ten additional units could be considered without crossing that reserve, so this source alone cannot cover the entire twelve-unit gap under the same rules. Revisit the offer’s scope, a genuinely timely alternative source or the release decision with the authorised owner. A fallback is a decision path, not permission to ignore the stock constraint.

Plan the Monday-after review before the Friday launch

On the on-time base assumptions, the destination closes with 44 units. A separate softer-demand case sells twelve small, 24 medium and twelve large, 48 overall. From the same 108 supply it leaves 24/twelve/24, sixty overall. That is sixteen more units than the base closing plan, worth $400 at an assumed $25 unit cost, not a confirmed loss or disposal.

Reconcile actual receipts, movements, sales and returns before deciding on the optional December repeat. Use Core to revise the remaining-season requirement and Core Plus to inspect where the suitable sizes are held. Assign the post-event review before launch so excess does not trigger another automatic-looking repeat. Readiness means the team knows what would change its decision before, during and after the offer.
