Seasonal campaigns in your shop: how to prepare sales, Black Friday and Christmas

The year's big campaigns can be your best weeks of takings… or a mess of stock-outs and discounts that leave no margin. The difference comes down to preparing ahead. This guide helps you arrive ready for every key date.

The retail calendar: get ahead of it

Every season brings its sales peak, and nearly all of them are predictable. If you mark them on the calendar weeks ahead, you arrive with stock, promotions and communication ready instead of improvising the day before. These are the dates almost no shop should ignore:

Winter and summer sales. January and July. You clear the previous season and make room for what's new.
Valentine's Day and back to school. February and September. Short campaigns, but with very specific products worth having ready.
Black Friday and Cyber Monday. Late November. The strongest peak of the year for many shops; prepare it weeks in advance.
Christmas. From December onward. Several weeks of high sales: gifts, hampers, seasonal products.

You don't need to tackle them all. Pick the ones that fit what you sell and throw yourself into those.

Prepare your stock in advance

The costliest mistake of a campaign is running out of the star product halfway through the big weekend. The second costliest is over-buying and dragging that dead stock around for months. To get it right, use your own data.

Tip: open the sales report for the same campaign last year in your POS. What you sold then is the best starting point for working out what you need now. Adjust upward if the business has grown.

With those numbers, place a reasoned order, not a guess: reinforce the products that flew off the shelves, order with room to spare the ones that sold out too soon, and be cautious with what was left over. Agree delivery dates with your suppliers before they're overwhelmed too.

Promotions that work without wrecking your margin

A promotion isn't giving money away: it's a lever to sell more, raise the average basket or clear stock. A flat reduction across the whole catalogue is usually the worst option, because it cuts margin even on what was already selling by itself. These alternatives tend to perform better:

Bundles. Group products that are bought together at an attractive combined price. You raise the basket without giving away margin unit by unit.
Volume discount. "3 for 2" or a lower price above a certain quantity. It pushes people to buy more on the same visit.
Second unit half price. Works very well on repeat-purchase products and consumables, and protects margin better than a straight 50% off.
Loss leader. One heavily discounted item that draws people into the shop; the rest of the basket sells at normal price.

Whichever you pick, work out the final margin BEFORE launching it, not just the discount percentage. A promo that sells a lot but leaves pennies per unit can have you working for free.

Communicate the campaign: start days ahead

The best promotion is worthless if nobody hears about it. Communication has to start before the campaign kicks off, not on the day itself. Combine the channels you have to hand:

1
Window display and signage. It's your best free advert. Change it a few days ahead with a clear message of dates and discounts.
2
WhatsApp. Let your regulars know with a short message. It's direct and almost everyone reads it.
3
Social media. Post in advance and remind people of the start date. A good photo of the loss leader goes a long way.

The key is repetition with time on your side: an early heads-up, a reminder and the final push on day one.

Measure the results with your POS

When the campaign ends, the part almost nobody does begins, and it's the one worth the most next year: looking at the numbers. Your POS stores everything you need to know what worked:

Common mistake: celebrating a campaign for record takings, then finding out the discounts ate your margin and you earned less than in a normal month. Always look at the profit, not just the sales.

Frequently asked questions

How far in advance should I prepare a campaign?

For big campaigns like Black Friday or Christmas, start four to six weeks ahead. You need time to order stock, set up the promotions and let your customers know. For smaller dates, one or two weeks is usually enough.

How do I know how much stock to order for a campaign?

Check what you sold on the same dates last year in your POS. That figure is your best starting point. Adjust upward if the business has grown or if you're going to promote a particular product more heavily.

How do I stop discounts from eating my margin?

Always work out the final margin before launching the promo, not just the discount percentage. Favour bundles and volume discounts, which raise the average basket, over flat reductions across the whole catalogue.
