Amazon’s holiday strategy

Over the years Amazon has developed a fairly advanced approach to handling the enormous volume of orders that characterises the Christmas period. Its strategy is based on two distinct macro-phases that require completely different approaches from sellers.

During September and October, Amazon’s entire logistics network focuses on receiving inventory. In this phase the fulfilment centres work at full capacity to take in sellers’ shipments and distribute the goods to the warehouses closest to the areas with the highest expected demand, so that products are ready to ship when the order peak begins.

Then comes the second phase. In November and December priorities change: the main goal becomes processing customer orders. Resources are diverted from receiving new inventory to picking and shipping orders and, as Amazon points out, during this period the time slots for delivering inventory to an Amazon facility are limited.

Sellers need to be aware of all this and, as a result, forecast their shipments precisely so they are not caught unprepared at the height of sales. But how?

Missed the 21 October deadline? What to do now

If your inventory did not reach the fulfilment centres by the date indicated, it does not mean losing the whole season, but you need to change your approach. Amazon sets arrival dates as a condition for Prime badge eligibility during events, so late stock is not guaranteed for the peak period. Here are the most sensible moves:

• Prioritise your best sellers: focus the space and shipments still possible on the ASINs with the highest margin and turnover.
• Consider FBM (direct shipping) for products that will not arrive in time, communicating realistic delivery times.
• Check shipments already in transit: if you use a non-partnered carrier, keep the expected delivery date range updated in the “Send to Amazon” workflow and act immediately with the carrier in case of delays.
• Do not submit deals you cannot sustain: you have until 18 November for Lightning Deals and Best Deals, but you need eligible ASINs, enough stock and margin. Calculate the real cost before committing.
• Avoid unnecessary listing changes: since 26 October Amazon has introduced new compliance questions for some categories of dangerous goods (fridges, air conditioners, shock absorbers, markers, pool products) that appear when you edit the offer. Even a small change to a title can trigger the questionnaire and slow down publication.
• Note the mistakes for next year: delays almost always come from planning that starts too late. Further on you will find how to set up a more prudent calendar.

Strategic management of capacity limits

In the months leading up to the holidays, space in Amazon’s fulfilment centres becomes a scarce and increasingly valuable resource. Smart management of capacity limits can make the difference between a successful season and one full of regrets.

The Capacity Monitor

The Capacity Monitor is a tool in the Fulfilment by Amazon dashboard that shows the capacity limits for the following month for each storage type, as well as the estimated limits for the next two months. For 2026 Amazon makes the estimates for October available from 23 July and those for November from 20 August. It should become a daily reference tool: it is not just about checking how much space there is, but about understanding trends and anticipating problems. Limits can change quickly depending, among other things, on

• sales performance
• the Inventory Performance Index score
• overall availability in the Amazon network.

Capacity Manager

When the standard limits are not enough to support your holiday sales strategy, the Capacity Manager feature lets you request additional capacity for your fastest-selling products, usually those that sell out in less than four weeks. It works like this:

• you submit a request indicating the maximum reservation fee you are willing to pay; no upfront payment is required;
• requests are allocated from the highest fee downwards until the available capacity runs out;
• if requests at a lower fee are later approved for the same period, those already approved are adjusted downwards to the lowest fee, so you can bid aggressively without the risk of paying more than necessary;
• sales generated with the additional capacity earn performance credits, which can offset up to 100% of the reservation fee: if you use the extra space well, the net cost can drop to zero;
• you can enable automatic cancellation, which cancels up to 100% of the request if the confirmed limit exceeds the previous estimated limit, so you only pay for the capacity you really need.

Amazon Warehousing and Distribution (AWD): extra space for peaks

If you expect higher volume during the holidays, Amazon recommends using Amazon Warehousing and Distribution (AWD): a service that lets you store large quantities of inventory at lower rates and automatically replenish fulfilment centres as needed. For 2026 there are three things to know:

• no AWD storage fees from 1 October to 31 December 2026 for eligible inventory in European distribution centres (other items, such as inbound and outbound processing and transport, remain at standard rates; storage charges resume from 1 January 2027);
• inventory automatically replenished from AWD to FBA is not subject to Fulfilment by Amazon capacity limits;
• to use it for Black Friday and Cyber Monday, inventory had to arrive at AWD centres by 7 October and the replenishment to FBA had to be created by 10 October.

Amazon also recommends relying on AWD when your FBA inventory covers more than 4-6 months of sales, to avoid storage problems and keep products available. If you do not use it today, consider planning it right away for next season.

Fees and costs to consider during the holidays

The holiday peak fulfilment fee

As last year, from 15 October 2026 to 14 January 2027 a holiday peak fulfilment fee applies to selected orders fulfilled by Amazon in Germany and the United Kingdom:

• United Kingdom: on average £0.12 per item for parcels and £0.07 per item for large envelopes and extra-large items;
• Germany: on average €0.27 per item for small and standard parcels.

The fee does not apply to oversize items, low-price FBA items or items delivered to buyers in other European Union countries. You can preview it in the Revenue Calculator and in the Fulfilment by Amazon Fee Preview report. Include it in your margin calculation to avoid wrong estimates.

The low-inventory-level fee

The Fulfilment by Amazon low-inventory-level fee is less likely to penalise you during promotional deals, because it takes into account long-term inventory performance over the last 90 days. To avoid it, Amazon recommends bringing enough inventory into the network to meet deal demand at least four weeks before the event and keeping availability above 28 days for subsequent sales too. It does not apply to new professional sellers for the first 365 days from the first inventory receipt, or to parent products enrolled in Fulfilment by Amazon for the first time for the first 180 days, provided they take part in the New Selection Programme.

How to ship to Amazon without delays

A long-term strategy requires planning that starts months earlier and that draws on experience from previous seasons, with a good safety margin. Amazon strongly recommends sending shipments in August and September, so that inventory reaches the fulfilment centres in time for Black Friday.

Planning must take into account not only standard lead times, but also

• supplier delays and carrier problems
• customs delays
• events such as a port closure or weather problems
• general overload of the logistics system.

That is why many sellers plan to have their inventory in transit by mid-September or early October, leaving a margin for the unexpected, and book their carrier well in advance.

Best practices

Some best practices recommended by Amazon:

• use “Send to Amazon” to create shipments and check progress in the Shipping Performance dashboard;
• provide an accurate delivery date range if you ship with non-partnered carriers: Amazon uses it to prepare for receiving and to alert you to delays;
• enter tracking details (carrier and shipping method) to make in-transit inventory available for sale sooner;
• check shipment data: units per box, number of boxes and total weight; if you omit box content information, the shipment is not eligible for automatic receiving and a manual processing fee is charged;
• apply team lift or mechanical lift labels to heavy items;
• for small parcels, the Inventory Placement by box programme simplifies shipment plans with multiple destinations.

For many sellers, carrier diversification is not just advisable but essential: relying on a single shipping service is a risk when a whole quarter’s sales are at stake. And real-time monitoring becomes a task that cannot be postponed. Tracking tools should be checked several times a day. Any sign of delay must immediately trigger a contingency plan.

How to keep stock and monitor inventory

Proper inventory monitoring lets you have enough items in stock to capitalise on faster delivery times. According to Amazon, on average sellers who maintain optimal inventory levels see a 15-20% increase in sales. Here is how:

• keep at least 28 days of inventory based on historical demand trends;
• use the inventory report and the Fulfilment by Amazon Inventory page to see replenishment recommendations (when to ship and how many units);
• consider AWD automatic replenishment to simplify stock management;
• monitor shipments with the Shipment events tab in the Shipment summary and with the Inventory Ledger report, which shows starting balance, received, orders, returns, removals and ending balance;
• if you use Amazon-partnered carriers, submit a missed pickup request in case of problems. With non-partnered carriers, act directly.

Also remember that many suppliers are saturated in the fourth quarter: ordering 8-12 weeks in advance prevents stock-outs.

The long-term economic and strategic impact

Sales concentrated during Black Friday and Cyber Monday are a strong seasonal peak. They often account for 25-30% of annual turnover for many sellers. A concentration of demand in a few days that leads to one conclusion: lost opportunities are practically unrecoverable. You cannot make up for them with later promotions or alternative strategies, because consumer buying behaviour during the holidays has unique characteristics.

Then there is another aspect: the impact on rankings and future visibility. Amazon rewards sellers who show reliability and management skills, and a seller who misses holiday opportunities due to logistics problems can be penalised in the following months too, creating a vicious circle that is hard to break.

Naturally, these rules apply to everyone, but even more so to highly seasonal businesses. Many product categories see most of their annual sales concentrated in a few months. For these sellers, missing the October deadline is equivalent to losing almost a whole year of business, with repercussions

• on supplier relationships
• on the capital available for new investments
• on the ability to compete in the long term.

Advanced strategies for professional sellers

The most experienced sellers have developed sophisticated strategies that they refine every year.

• Staggered shipments: instead of concentrating everything in a single shipment, they spread stock across several shipments that arrive over time. This reduces the risk of losing access to holiday sales and lets them test demand before committing all their inventory.
• Predictive tools: they analyse historical data to understand how it affects delivery times and identify the best shipping windows to meet deadlines.
• AWD and automatic replenishment: they store excess stock in AWD centres and let Amazon replenish FBA based on demand, without saturating capacity limits.
• Direct ocean freight: those importing from China can consider Amazon Global Logistics, the ocean freight service connected to Amazon’s logistics network (Amazon indicates a discount of up to 8% on bookings for 60 days from acceptance for new profiles, with terms that may vary).
• Informal seller networks: small groups that share information on the most reliable carriers, emerging logistics problems and contingency strategies.

After the holidays: reimbursements, returns and analysis

The season does not end in December. After the peak, take stock on three fronts:

• Reimbursements: claim windows do not send reminders. Inbound discrepancies can in practice be reported for about five months, warehouse losses and damage have 60 days, returns and removals range from 60 to 120 days depending on the case.
• Returns: the extended return window closes on 31 January 2027.
• Analysis: compare sales with forecasts, assess which products sold more than expected and which stood still, and decide what to do with unsold seasonal inventory.

Holiday inventory checklist

• Plan shipments for August and September next year and check the dates in Amazon’s guide.
• Check the Capacity Monitor every week and consider Capacity Manager and AWD for your best sellers.
• Keep at least 28 days of inventory and check the replenishment recommendations.
• Include holiday fees and other fees in your margin calculation.
• Provide delivery dates and tracking details for every shipment with non-partnered carriers.
• Diversify carriers and have a contingency plan.
• Submit deals by 18 November only for products with stock and margin.
• Monitor reimbursement windows and return deadlines after the event.

Inventory management: more and more often the competitive advantage you need

It is clear that the ability to manage the October deadline effectively has become over the years one of the main competitive differentiators in the Amazon market. Having good products or competitive prices is not enough. You need to show logistical and strategic skills that few manage to handle correctly.

Sellers who turn this obstacle into an advantage develop standardised processes that they replicate year after year:

• detailed checklists
• precise timelines
• emergency protocols that let them face the critical phase with confidence and control.

Mental preparation counts as much as logistical preparation. The pressure in the months before the holidays can be intense and clear decision-making becomes crucial.

In short, the October deadline is an annual test of an Amazon business’s maturity. Those who pass it show they have understood the deeper dynamics of the platform. Those who fail it face not only immediate financial losses, but also the need to rethink their approach.
