Short-video sales spikes: how to keep your supply chain ahead of demand

A short video can send more orders in a weekend than you planned for the whole month. If the product has not been approved, or the stock is not there, a good campaign becomes a bad week: late orders, cancellations and angry customers.

This is how we plan for it with brands selling in Spain and Japan.

In short

• Treat a demand spike as a stock and supplier problem, not only a marketing one.
• Decide how much stock each channel can use before you promote anything.
• Track orders, quality, stock, delivery and returns together.

Get ready before you scale the content

A campaign can create demand before anyone has checked the product or secured stock. Before you push, make sure you have:

• An approved supplier and approved sample.
• A real view of your stock.
• Packaging and quality checks done.
• A route and delivery promise you can keep.
• A plan B if demand beats your forecast.

Then set rules in advance: what makes you slow the campaign down, when you reorder, and when you change the shipping route.

One stock, several channels

Most brands sell the same product through a distributor, their own store, a short-video campaign and maybe a marketplace. If they all draw from the same stock, you need to decide who gets what.

Give every demand a status: firm order, normal forecast, planned campaign or unproven opportunity. A viral video should never quietly eat the stock you already promised to a wholesale customer.

For each product, write down:

• Stock you can actually use: accepted units, minus reservations and anything on inspection hold.
• Demand by channel: firm orders apart from forecasts, with the date and source of each assumption.
• Priority rules: who comes first, and what happens to stock nobody uses.
• Trigger: what event changes your buying, promotion or routing, and who decides.

An example

Say you have 1,000 accepted units shared by a Spain distributor, a Japan retail program and a video promotion. The distributor has 400 committed and Japan has 250. That leaves 350 units. If the promotion is aiming for 500, you have a decision to make: find more eligible stock, or cap the campaign.

Be careful not to subtract the same commitments twice if your system already shows them as reserved. And check real production and arrival dates before you count on a reorder to cover the gap. These numbers are invented, just to show the logic.

Views are not purchase orders

Views, clicks, waitlists and orders are different signals. A short burst of attention can justify a small, controlled campaign. It rarely justifies a large order you cannot undo.

Work with a low, base and high scenario, and check each against what your supplier and your cash can handle. If the product cannot arrive while the buzz lasts, say so. A limited offer, a different product or a later campaign is better than urgent buying that leaves you with dead stock.

Spain and Japan are not the same plan

Review each market separately when customers, routes, receiving rules or pack versions differ. Share supplier and quality records where they genuinely apply to both. And check each platform's current rules on its official seller pages before launching: the channels are not identical in both countries.

After the campaign, compare what you allocated with what you sold, cancelled, received and still have. If one channel keeps overestimating and draining the shared stock, fix the rules. Keep a log of every time stock moves from one channel to another, with the reason and who decided. Without it, every team believes its demand was approved while the stock cannot cover them all.

FAQ

Does a demand spike always justify a big production run?

No. Check quality, repeatability, margin, delivery promise and your replenishment plan first.

How do I protect customers if I run out of stock?

Use accurate inventory, clear availability rules, staged campaigns, a backorder decision and a documented way to tell customers.

Who should own the go/no-go decision?

Marketing or sales can trigger it, but purchasing, quality, operations, logistics and finance should sign off together.
