Mexico's Buen Fin — the November shopping event that concentrates much of the retail year — is not won in November. It is won in September, when there is still time to secure space, hire people and prove the process holds. Whoever starts preparing in October is negotiating over whatever is left.
Stage 1 — Three months out: size the peak
Everything depends on one number: how many orders you will ship on your worst day.
Not the weekly average. The worst day. Because operations break at the peak, not at the mean.
How to calculate it:
- Take the highest day of last season
- Apply your actual growth for the year (not your commercial target — your observed growth)
- Add margin for the campaign marketing has not told you about yet
With that number, calculate three things: how many inventory positions you need, how many person-hours of preparation, and how many outbound units leave per day.
Stage 2 — Two months out: secure capacity
Space. Season inventory arrives before the sales do. You need somewhere to put it weeks before the first order.
Here is the classic trap: contracting fixed area for the peak means paying that peak twelve months. The alternative is a model that bills by real occupancy — pallet-position rental is invoiced by month or fraction, which lets you take relief space only for the months you need it.
Preparation. This is the underestimated one. The inventory fits; the work does not. Confirm who will prepare the orders and at what hourly capacity.
Materials. Boxes, void fill, tape, labels. They run out in the market exactly when everyone needs them.
Stage 3 — One month out: freeze and test
Freeze changes. Do not switch systems, packaging suppliers or carriers within a month of the peak. Anything new will fail precisely when you have no margin to fix it.
Run a load test. Pick a day and process real volume at the expected peak rate. Not a paper simulation — an operational test. You will find the real bottleneck, which is almost never the one you assumed.
Verify the dispatch bench. After preparation, the second point that saturates is carrier pickup. If your collection window is narrow, all the upstream work piles up there.
Stage 4 — During: three daily indicators
| Indicator | What it reveals | Alarm signal |
|---|---|---|
| Orders prepared per hour | Real capacity | Falls while volume rises |
| Backlog at end of day | Whether you are keeping pace | Grows two days in a row |
| Error rate | Whether speed is costing quality | Rises alongside volume |
Backlog is the most important. A pending queue growing two consecutive days does not correct itself: it corrects by adding capacity or by ceasing to promise delivery dates you cannot meet.
What breaks first
Against intuition, it is almost never space. The usual order is:
- Preparation capacity — not enough hands per hour
- Dispatch bench — the pickup window cannot absorb the volume
- Packing materials — they run out at the worst moment
- Space — usually last
That is why sizing by square meters alone is a mistake: the inventory fits, the work is what does not.
And afterwards: returns
The season does not end when the selling ends. December and January bring the returns wave, which must be received, inspected, reconditioned and restocked. Budget that capacity now — it is part of the real cost of the season.
How an operator absorbs it
Fulfillment — picking, verifying, packing and dispatching order by order — combined with flexible pallet-position rental turns the two resources that saturate (space and hands) into capacity you can contract by season, without carrying it the rest of the year.
Our Querétaro park sits next to the Intercontinental Airport, where the major parcel carriers operate — which shortens exactly the point that saturates most during the peak.
