How to prepare your shop for the sales season

Sales, Black Friday, Christmas, back to school… sales peaks can be your best weeks of the year or a mess of empty shelves, checkout queues and discounts that leave no margin. The difference isn't luck: it's preparing ahead. This guide walks you step by step through what to have ready before the rush arrives.

1. Restock what really sells

The costliest mistake of a campaign is running out of your star product on Saturday afternoon with the shop full. The second costliest is over-buying and dragging that dead stock around for months. You don't need to guess to get it right: your own sales tell you what to reinforce.

Before you place the order, rank your products by units sold and keep the ones at the top. Those are the ones that move the till and the ones you can't afford to run out of mid-campaign. The rest of the catalogue matters less: if something hasn't sold in months, this isn't the moment to fill the stockroom with more of the same.

Tip: in Bipe you can see your best-selling products and their rotation at a glance. Open the report for the same campaign last year: what you sold then is the best starting point for working out what you need now, adjusting upward if the business has grown.

With those numbers, place a reasoned order instead of a guess: reinforce the ones 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. And lock in delivery dates with your suppliers as early as possible, because in peak season they get overwhelmed too and a delay leaves you without stock on your best weekend.

2. Set discounts with your head (without killing your margin)

A discount isn't giving money away: it's a lever to sell more, raise the average basket or clear specific 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. Before you announce anything, be clear on how much you keep after the discount, not just the percentage on the poster.

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 take 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.

Save the big reductions for the stock you genuinely need to clear — last season's items, the ones taking up space — not for your best sellers, which would go anyway without a discount. Have your campaign prices set in advance so you're not improvising calculations with the queue waiting.

3. Set up your POS for fast, queue-free checkout

On a normal day a slow till barely shows. In the middle of a campaign, with the shop full, every extra second at the counter is a growing queue and customers who get tired and leave their basket on the shelf. Fast checkout isn't a detail: it's money coming in or walking out the door.

Everything with a barcode and the right price. Check that the campaign products scan properly and have an up-to-date price. Keying items in by hand on the busy day is what jams the till.

Discounts already loaded in the POS. If the "3 for 2" or second unit applies itself when the product is scanned, your team calculates nothing and makes no mistakes. With Bipe you set the discount once and the till applies it on every sale.

Quick, varied payment. Have card and mobile payment ready, not just cash. The more fast payment methods you offer, the less the queue jams.

Spend ten minutes the day before running a couple of test sales with your star products: checking that everything scans and that the discounts trigger by themselves saves you nasty surprises when the shop is packed.

4. Organise the team and the shifts

The best stock and price prep falls apart if on the big day there are two of you serving thirty. A campaign's peak hours are predictable: look at what times sales cluster in your reports and add staff right there, not evenly across the whole day.

Split the tasks so nobody has to do everything at once: someone fixed on the till taking payments, someone restocking the floor so it never looks empty, someone answering questions and guiding customers. And before you open, spend five minutes explaining to the team what's on promotion, where it is and how each discount applies in the POS. A staff member who knows the campaign sells; one who discovers it on the fly slows the queue.

Tip: get the change float ready and a cash forecast in place before you open. Running out of coins or change during peak hour is another silly way to slow sales down.

5. Measure what worked afterwards

When the campaign ends, the part almost nobody does begins, and it's the one worth the most for next year: looking at the numbers calmly. Not to beat yourself up, but to repeat what went well and drop what didn't. Your POS stores everything you need:

What sold. The campaign's top products, so you can reinforce them and order in time next year.
What margin you really kept. Not just how much you billed, but how much you made after applying the discounts.
Which promotion pulled and which didn't. The bundles and offers that lifted the basket versus those that only cut margin.
How the takings moved. The busiest hours and days, so you can fine-tune shifts next time.

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.

Jot down in a couple of lines what worked and what didn't. Next year, that small summary is worth more than starting again from scratch.

Frequently asked questions

How much stock should I reorder for the sales?

Start from what you sold in the same campaign last year. Reinforce the products that were your best sellers and be cautious with what was left over. Adjust upward if the business has grown, but avoid filling the stockroom with stock you'll drag around for months.

How do I set discounts without losing margin?

Work out the margin you're left with after the discount before launching it, not just the percentage. Favour bundles and volume discounts that raise the average basket, and save the big reductions for the stock you genuinely need to clear.

How do I avoid checkout queues on the busy days?

Make sure products have a barcode and the right price before the campaign, set the discounts up in your POS so you don't calculate them by hand, and add staff during peak hours. Fast checkout stops customers getting tired and abandoning their basket.
