Black Friday inventory planning, counted backward from the sale
Black Friday lands on 27 November. If your goods come by sea, the decision about how much stock you will have that day is being made now, in late August, whether you make it deliberately or not.

The decision has a date, and it is not in November
If your Black Friday stock comes by sea from Asia, the last day to place the order lands in late August or early September, and if the goods still need to be produced first, it has already passed. That is not a scare line. It is the arithmetic of a boat, and every step of it is laid out below so you can check it against your own supplier and lane.
Black Friday falls on Friday 27 November this year, with Cyber Monday on the 30th. Nothing about the date is a surprise, which makes the annual scramble strange when you think about it. A store that never misses a tax deadline misses the ordering deadline for its biggest weekend, because nobody wrote that deadline down anywhere. No screen you look at daily counts down to it. The shelf looks fine in September, and the shelf is not where the truth is.
The reason is lead time. A sea shipment takes around three months door to door once sailing, customs and the truck to your warehouse are counted, and any production time at the factory sits in front of all of that. Walk backward from late November and you land in late summer. That is why this page exists in August rather than October.
Work backward from 27 November
Subtract each step from the sale date. These are typical shapes for an Asia to Europe or Asia to US lane, not quotes. Your product, port and forwarder will move every row by a week or two in either direction, which is exactly why you should run this once with your own numbers and put the result somewhere you will see it.
| Around when | What has to be true | What eats the time |
|---|---|---|
| Friday 27 November | Black Friday. The selling window runs through Cyber Monday on the 30th. | |
| Mid November | Goods received, counted and live in your store. | Two weeks of margin, because boats are late often enough that planning for the on-time case is planning to gamble your biggest weekend on a schedule. |
| Around 1 November | The vessel docks at your port. | Customs clearance, the inland truck and putaway are days you do not control. |
| Around mid September | The container sails. | The crossing alone commonly runs six to seven weeks on Asia lanes. |
| Early September | Goods leave the factory for the port. | Booking, export paperwork and the truck to the port take about a week. |
| Late August to early September | You place the order, if the factory ships from stock. | Confirming the order, paying the deposit, reserving the space. |
| Late July to early August | You place the order, if the goods must be produced. | A production run commonly adds 30 to 45 days, and none of it appears on a freight quote. |
Read the last two rows again. If your supplier ships from stock, the deadline is roughly now. If your goods are made to order, the sea deadline for this Black Friday passed while you were on summer holiday. That does not mean sitting the weekend out. It means changing freight mode, which is covered further down.
How much to order for a spike you cannot see yet
Quantity is the second question, and it is genuinely harder than timing, because a spike is exactly the thing a sales history is worst at predicting.
Your own numbers from last Black Friday, if you have them, are the only source worth opening. For each product, compare what it sold across the Black Friday weekend with what it sold in an ordinary week of the same season, and carry that lift over to this year's baseline rate. Do it per product rather than store-wide, because the lift is never even: a discount weekend pulls hard on a handful of products and barely touches the rest. Afterward, keep that week fenced off from your ordinary forecasting, because a discount spike is a price event rather than a demand signal, and fed in as demand it inflates every forecast that follows.
If this is your first Black Friday, be honest with yourself about what you are doing: guessing. There is no calculation that turns zero history into a forecast, and anyone selling you one is selling the decimal points, not the answer. Our own forecasting post lists first-time events among the things no forecast handles, and that rule does not bend for November.
A guess can still be made well. Pick a multiple of normal demand you can defend out loud, then weigh the cost of being wrong in each direction. Order too little and you lose sales for a few days on your loudest weekend, which stings and then ends. Order too much and the surplus sits in the warehouse as cash you cannot spend, possibly until spring. Which wrong is worse depends on your margin and your cash position, but it deserves ten deliberate minutes, not a shrug.
The split that keeps the guess cheap
You do not have to place one bet in August. The stronger play is two orders with different jobs.
The base goes by sea now, sized to the amount you would be glad to own even if Black Friday disappoints. A useful test: would this stock sell through at normal prices over the following months anyway? If yes, the downside of the bet mostly disappears, because the worst case is ordinary inventory arriving early.
The bridge is a smaller, faster order placed closer to the date, once real signals exist: October traffic, early November sales, how pre-orders or waitlists are moving. Rail if you decide by mid October, air if you decide later, and in either case a fraction of the total rather than a second full order. You pay premium freight only on the units the signals told you to add.
This is the same split-order logic that applies to any long lead time, aimed at a date instead of a stockout. The mechanics are in our freight planning post.
Reading this too late for sea
The options narrow in a fixed order, and each one costs more per kilo than the last.
| Mode | Rough order deadline for 27 November | Cost shape |
|---|---|---|
| Sea, factory ships from stock | Late August to early September | Cheapest by a wide margin |
| Rail | Around mid October | Between sea and air |
| Air | Into early November, at a squeeze | Several times sea per kg |
Rail takes several weeks door to door and sits between the boat and the plane on price, which makes it the natural fallback through September and into October. After that comes air, with one hard rule: never put the whole order on a plane. Fly the units the weekend genuinely needs and let the rest come by sea for the new year, because air freight at several times the sea rate can quietly eat the margin the discount weekend was supposed to earn.
The other late move is narrowing the bet. Deep on a few products you believe in beats shallow on forty, because late freight is priced per kilo and every kilo should be one you expect to sell that weekend.
The bill arrives in January
Over-ordering for a spike has a delayed cost that never shows on the November dashboard. The weekend ends, the surplus stays, and the cash that bought it is trapped on shelves instead of paying for the spring orders. Stores discover this in January as a strange broke feeling in what was supposedly their best quarter, and the mechanism is laid out in our post on being profitable with no cash in the bank.
The defence is the base-and-bridge split above. Cap the sea order at what you would own anyway, and let the fast, small bridge carry the speculative part. A freight premium on a few hundred units is cheaper than a warehouse of regret.
Which products deserve the bet
Fewer than you think.
Your strongest sellers, the products that would headline the sale anyway, earn the stock and the buffer. Those are the ones where an empty shelf on the Saturday actually costs something.
The long tail does not earn it. A slow mover ordered deep for Black Friday is the classic way to buy next year's dead stock, and where the supplier demands a big minimum order quantity the trap is worse, because the MOQ turns a small bet into a large one whether you wanted that or not. If a C-product sells out mid-weekend, let it. That sentence looks wrong and is usually right.
Where this advice runs out
Everything above is shapes, not quotes. Lead times differ by lane and by product, freight in the run-up to Q4 tends to run slower and busier than the rest of the year, and your forwarder's dates beat this page's dates every time. Run the backward timeline with real numbers before acting on it.
And the sizing question stays partly unsolvable. Restocio computes order deadlines and sea, rail and air splits from your own sales history, which is exactly the machinery a Q4 plan runs on, but it cannot know how big your first Black Friday will be any more than you can. History-based tools work from history, a first-time spike has none, and so the multiplier is yours to choose. The honest job of software here is to make the deadline visible and the freight split cheap once you have chosen.
Common questions
When should I order Black Friday stock?
For sea freight from Asia, late August to early September if your supplier ships from stock, because the door-to-door journey runs around three months once customs and inland transport are counted. If the goods need a production run first, add roughly a month, which pushes the real deadline into midsummer. Rail buys you until around mid October, and air into early November at several times the cost per kilo.
How much stock should I order for Black Friday?
There is no universal multiplier. If you traded last Black Friday, measure your own per-product lift against an ordinary week of the same season and apply it to this year's sales rate. If it is your first, it is a guess: pick a multiple you can defend, put the amount you would be happy to own anyway on sea freight, and hold back a smaller fast order until October signals tell you whether to add more.
What if I missed the sea freight deadline?
Move down the ladder. Rail takes several weeks door to door and costs between sea and air, which makes it the fallback through September and October. After that, fly a fraction of the order, never all of it, and concentrate the spend on your best sellers rather than spreading it across the catalogue.
Should I stock up on every product for Black Friday?
No. The lift concentrates on a handful of strong products, and those deserve the stock and the safety margin. Ordering deep across the long tail is how Black Friday surplus becomes dead stock, especially where a supplier's minimum order quantity forces the bet to be larger than you intended.
What happens to unsold Black Friday stock?
It sits in the warehouse as trapped cash, usually until it gets discounted in the new year. The protection is deciding up front that the sea-freighted part of the order is stock you would be happy to own in a normal winter, and letting the smaller, faster bridge order carry the speculative part.
