If you start planning for Black Friday in October, you’re already late.
October is when Q4 starts to feel urgent. It is also when the options available to you start getting smaller.
By then, stock has usually been committed. Supplier lead times are tightening. Warehouse capacity is harder to change. Creative is moving into production, and development teams are trying to balance campaign requests against the risk of making changes during the busiest part of the year.
There is still plenty a business can do in October, of course. But it should be testing and refining the plan by that point, not trying to create it from scratch.
I learnt this first-hand in a previous in-house role.
The marketing and commercial teams had agreed on a series of discounts. These ranged from 10% to 50%, with some particularly slow-moving stock reaching 75% off. The commercial plan was clear enough. The technical requirement was not.
The discounting functionality on the EpiServer platform had not been built to support the campaign’s stacking rules. Customers could apply multiple promotions to the same basket when they should not have been able to.
We were dealing with it days before launch. The development agency was under enormous pressure to build and test a solution, and a promotional decision had suddenly become an urgent technical project.
Nobody had deliberately created the problem. The teams had simply planned their own parts of the campaign at different times.
That experience has stayed with me. Q4 cannot be treated as a Black Friday marketing campaign. It needs to be managed as a three or four-month trading programme that the whole business can deliver.
Peak is much bigger than Black Friday.
For most ecommerce businesses, peak is no longer one weekend.
Promotions can begin in October and build throughout November. Black Friday and Cyber Monday are followed almost immediately by Christmas gifting, delivery cut-offs, Boxing Day, clearance and the January returns period.
Adobe recorded £26.9 billion of UK online spending between 1 November and 31 December 2025, but that demand was not all the same. Some customers were looking for a bargain. Others were researching gifts, waiting for payday or trying to find something that could still be delivered before Christmas.
Planning each of those moments as a separate campaign creates problems because they all rely on the same stock, people, systems and fulfilment capacity.
I prefer to start with one Q4 plan covering September through to January, then build the individual trading moments over it.
Reactive campaigns create pressure everywhere.
Most ecommerce teams will recognise the pattern.
A sale launches but does not hit its expected rate of sale. More emails are requested. Creative changes. Paid spend moves. Then a deeper discount starts being discussed.
Customers recognise the pattern too. If a brand has moved from 20% to 30% and then 40% off in previous years, some people will simply wait. Why buy now if a better offer is likely next week?
Those who have already ordered may cancel and reorder. Customer service receives requests for the difference to be refunded. The warehouse deals with avoidable picking, packing and order changes, while returned or cancelled stock has to find its way back into availability.
What looks like a simple trading decision can create work across ecommerce, marketing, technology, operations and customer care.
This does not mean a promotion should never change. It means the team should agree in advance what it will do if demand is above or below plan.
Why I still like the idea of “Christmas in July”.
One of the best marketing managers I worked with used to talk about “Christmas in July”.
During a relatively quiet part of the year, she would bring a small group together to create the first version of the peak plan. We started with the stock we knew was likely to be available, then looked for products that could work as gifts, connect naturally with other activity and give new customers an accessible first purchase.
It was a focused exercise. It did not need the whole business in a room for days.
Once the direction was agreed, teams had August and September to develop the creative, set up the campaigns and work through the customer journey. The process was calmer, but more importantly, the work was better. People understood what the business was trying to achieve and had time to challenge or improve the plan.
July will feel early to some businesses. That is exactly why it is useful. There is still time to make meaningful choices.
A practical 12-week Q4 ecommerce plan.
There is nothing magical about exactly 12 weeks. The timing will move depending on the business, its products and its supply chain. What matters is doing the work in the right order.
Eight to twelve weeks out.
This is the time to make decisions that will become expensive, risky or impossible to change later.
- Build base, upside and downside forecasts for sales, orders and units, not revenue alone.
- Identify priority products using demand, margin, stock cover and supplier lead time.
- Confirm supplier quantities, expected arrival dates and contingency options.
- Model warehouse, carrier and customer service capacity against the upside forecast.
- Agree the promotional structure, including margin floors, exclusions and stacking rules.
- Create one Q4 change calendar covering the website, checkout, apps, integrations and tracking.
- Give the programme a clear lead, named owners and agreed escalation routes.
The output should be one plan that Finance, Trading, Marketing, Operations, Technology and Customer Service can all recognise.
If Marketing is forecasting sessions, the warehouse is planning orders and Finance is working from revenue, but none of those numbers connect, you do not yet have a shared peak plan.
Four to six weeks out.
October should be used to check the plan against what is actually happening.
- Reforecast using recent trading, current stock receipts and revised supplier dates.
- Receive and quality-check priority stock where possible.
- Test the complete mobile journey from campaign click to order confirmation.
- Test search, collection pages, product pages, basket, checkout and stock updates under load.
- Validate CRM audiences, consent, suppressions, automations, links and promotional codes.
- Prepare fallback creative for low stock, sold-out products and delivery changes.
- Train customer service teams on the offers, cancellation rules, returns and likely exceptions.
This is where you want to find the gaps, while there is still time to do something about them.
One to three weeks out.
The final weeks should be about control, not invention.
Run a production-like order all the way from arrival to refund. Test payment, fraud checks, inventory reservation, warehouse processing, carrier handover, tracking, cancellation and returns.
At the same time:
- freeze unnecessary high-risk changes;
- confirm warehouse rosters and carrier collections;
- check prices, promotional stacking, stock limits and legal wording;
- activate checkout, payment and order monitoring;
- agree spend limits and rules for pausing unavailable products;
- publish one delivery promise across the website, checkout, FAQs and customer service.
If something fails at this point, the owner and fallback should already be clear.
Peak week through to January.
Black Friday is not the finish line.
During the main promotion, I would run a short daily trading meeting covering net sales, contribution, stock, website performance, payments, fulfilment, carrier performance and customer contacts. The point is not to read a dashboard aloud. It is to spot what is moving away from plan and agree what needs to happen that day.
As December progresses, the emphasis moves from discounting towards gifting, availability and confidence in the delivery promise. After Christmas, it changes again to clearance, returns, refunds and getting resellable stock back on sale quickly.
The people needed to manage peak cannot all stand down on 1 December.
Put the whole plan on one page.
A useful Q4 plan does not need to become another enormous deck. At a minimum, it should answer seven questions:
- What demand are we planning for under base, upside and downside scenarios?
- Which products and categories matter most, and what role does each play?
- Do we have the stock, people, systems and delivery capacity to support that demand?
- What are the commercial limits for discounting, margin and paid spend?
- What promise are we making to customers throughout the season?
- Which measures will tell us early that performance is moving off track?
- Who can make each decision when something changes?
If those answers are spread across several decks, spreadsheets and inboxes, bring them together before adding any more campaign detail.
Smaller teams benefit just as much from starting early.
At blubolt, we work with plenty of smaller and founder-led businesses where ecommerce and marketing may sit with one or two people.
In those teams, Black Friday can stay in the background until a few weeks before launch. Agencies and creative partners are then asked to pivot quickly and make the best of the time left.
Starting earlier gives everybody more room to contribute. There is time to build a teaser campaign, grow the addressable audience, capture useful customer data and create nurture journeys before the main event. The team can also plan what happens after the promotion, rather than losing momentum as soon as it ends.
More time does not just make delivery easier. It gives the business more options.
Start while you still have choices.
An early plan will not make Q4 predictable. Stock will still arrive late. Demand will move. A hero product may sell faster than expected, and a carrier may struggle.
The difference is that the business can respond without making everything up in the moment.
For me, peak readiness is not about trying to predict every problem. It is about creating enough visibility, capacity and decision-making clarity to deal with issues before customers feel them.
At blubolt, we help ecommerce teams connect the trading plan with the customer journey, site experience and reliable data needed to manage peak well. If your Q4 planning still begins with a campaign calendar in October, the first change is simply to start the conversation earlier.
