A busy Black Friday weekend can leave a quiet question on Monday morning: what did the offer actually change?
The order count will not answer that on its own. Some customers may have brought forward a purchase. Some may have bought the same thing at the usual price. Others may be trying your business for the first time.
Those outcomes have different values. A useful promotion brief decides which one the business is trying to create before the team chooses the headline or the discount.
The opportunity includes a question of trust
Black Friday falls on 27 November this year. There is still time to decide what participation should achieve.
YouGov’s October 2026 Great Britain report says 47% of likely Black Friday and Cyber Monday shoppers find it difficult to know whether discounts are genuine. That describes the likely shoppers surveyed, rather than every British consumer or the quality of any particular retailer’s offers.
A larger percentage sign does not resolve that uncertainty. The customer still needs to understand the product, the actual saving and why buying from you is a sensible choice.
Brand strategy has a job here: connect a short-lived offer to the reason the business deserves to be chosen after the event ends.
Choose the behaviour the offer should change
Start with one primary commercial purpose. You might want to introduce a specific product to first-time buyers, sell through a defined stock line or help an existing customer take a useful next step.
Write down who you are trying to help and what you want them to do differently. “Grow sales” leaves too many decisions open. “Help first-time home brewers choose their first complete setup” gives a specialist retailer a much clearer task.
Stock clearance and customer recruitment may need different products, messages and measures. Put them into separate offers if combining them would make either harder to understand.
For a service business with limited capacity or a long buying cycle, a blanket seasonal discount may have little useful role. The calendar does not make every offer relevant.
Count what the discount costs each order
Consider a deliberately simplified example, with prices and costs stated excluding VAT:
- A product sells for £100 and has £60 of variable costs, leaving £40 per order towards fixed costs and profit.
- A 20% discount reduces the selling price to £80. With the same £60 variable cost, that contribution becomes £20.
- The business would need 200 discounted orders to produce the same £4,000 contribution as 100 orders at the usual price.
That is arithmetic under stated assumptions, not a sales forecast. It excludes extra campaign costs, changes in fulfilment costs, returns and capacity constraints. Those could make the required volume higher.
Ask finance or the person responsible for the accounts to model the actual offer. Include payment fees, delivery, packaging, any added service and a realistic allowance for returns. Separate costs that change with each order from costs that will be incurred anyway.
The question is whether the expected change in customer behaviour justifies that commitment. A discount can be a useful investment when the business knows what it is buying.
Make the offer fit the reason people choose you
Imagine an independent retailer known for helping people get started with home coffee equipment. This is an illustrative example, rather than a client result.
A discount across every product might generate orders without helping a beginner make a better choice. A clearly specified starter set, with compatible components and a booked setup session, could address the uncertainty that was stopping that customer buying.
The bundle and staff time still have costs. There is no automatic advantage in giving something extra instead of reducing the price. Compare the economics and the customer usefulness of each option.
The strategic choice is what the offer demonstrates. If expertise is part of the position, the promotion should give customers a useful experience of that expertise.
My earlier article on brand strategy and pricing power examined why buyers need a defensible reason to pay. This is a narrower decision: what should one temporary offer help a particular customer do, and at what cost?
Make the value easy to check
In its 26 October guide to the 2026 sales, Which? explains that it checks market prices over six months when assessing deals, looking at the lowest and average prices it has seen. Its checks do not include every retailer.
That is a useful reminder that customers can compare a promotional story with a longer price history.
Be precise about what is included, the basis of any saving, the products covered and any important conditions. If a set contains different items from the usual offer, make the comparison understandable. Have price claims and terms checked through the business’s normal review process.
Give the customer a straightforward reason to act within the offer period. Keep the end date and availability accurate. A promotion built around personal advice needs a credible limit on the appointments available.
Check the busiest day against the brand promise
A campaign can increase demand more quickly than the business can increase service.
Before launch, ask who will answer questions, how stock will be kept accurate and which delivery dates the team can support. If the offer includes advice or setup, decide how that time will be booked and delivered.
Agree what happens if demand exceeds capacity. That might mean closing appointment slots, limiting the offer to available stock or changing the advertised delivery date clearly before a customer commits.
The first experience matters especially when the promotion is meant to recruit people who will return. The offer should give them a fair experience of the business you want them to choose again.
Judge the result after the noise has passed
Agree the review before launch. Track the outcome that matches the purpose: stock sold through, contribution after the relevant costs, or new customers and their later behaviour.
Look beyond the promotional weekend to returns and the following trading period. Investigate whether sales were additional, shifted from a later date or moved away from another product.
Use a realistic baseline. Where feasible, plan a comparable group that does not receive the offer. Differences in stock, audience, advertising and timing still need attention; a simple before-and-after comparison does not establish what the promotion caused.
For a small business, the evidence may remain imperfect. Record what you know and what you are estimating. That is more useful than treating every order carrying a campaign code as a new sale.
Give the next offer a short leadership brief: which customer, which decision, what contribution, what delivery commitment and what evidence afterwards?
Once those answers are clear, the creative team has something worthwhile to make visible.
Black Friday promotion planning: direct answers
What should a business decide before running a Black Friday offer?
Choose a specific customer behaviour the offer should change, model its contribution after relevant costs and check that stock, service and delivery can support the promise. Agree how the result will be reviewed after the event.
Does a 20% discount require 20% more sales?
The required volume depends on costs. In the illustrative example here, a £100 sale with £60 variable costs contributes £40. A 20% discount reduces contribution to £20, so twice as many orders are needed to match the previous total before extra campaign costs.
How can a promotion support a brand strategy?
An offer can demonstrate the expertise, convenience or other value the brand wants to be known for. Its products, terms and delivery should help a defined customer make a useful decision, with measures that show whether the commercial purpose was served.
