Groceries: your information expires every day
Your stock and your prices will be wrong by tomorrow afternoon. All the usual advice assumes a cadence this trade cannot keep.
A grocer, a mini-market or a supermarket publishes the most perishable information of any trade. A restaurant’s menu holds for a season and a garage’s hours hold for a year; your stock and your prices are wrong by the next day.
That is what makes nearly everything you are advised to do inapplicable. "Keep your catalogue up to date" assumes a cadence nobody in this trade can sustain, and a catalogue that lies on Thursday does more damage than no catalogue at all.
The consequence is not to give up. It is to sort: your shop holds information that does not move, information that moves slowly, and information that changes daily. The three are not published in the same place or in the same way.
So this is the only article in the series that recommends publishing less. It starts with what actually decides which shop somebody walks into, and it ends with what we refuse to put online on your behalf.
What decides is not your range
A customer does not choose a shop by the length of its shelving. They choose it on distance, on opening hours, and on a very small number of prices they know by heart because they buy them every week.
Those few lines are your shop window whether you like it or not. They work as a thermometer: if they are expensive at your place, everything is assumed expensive, even when the rest is not.
That has a commercial consequence many shopkeepers apply by instinct without putting it into words: on those lines you are not earning margin, you are buying a reputation for price.
The consequence for what gets published is more interesting still: those are the only prices worth showing online, because they are the only ones people search for and check.
The rest of the range is not listed, it is described. "Fruit and vegetables", "dairy", "frozen", "halal aisle", "gluten-free": information that does not perish and that answers the real question, which is "will I find what I am looking for".
Sort what does not move, what moves slowly, what changes daily
That sorting is the central job in this sector and it is done once. What does not move: the address, the departments you carry, the payment methods accepted, whether there is parking, the access. Information good for years.
What moves slowly: the hours, which change with seasons and festivals; the services, such as delivery or telephone ordering; and the list of brands you stock permanently.
What changes daily: prices, deliveries in, stock-outs, promotions. That category must never go on a page, because a page remembers and turns up in a search engine six months later.
The rule that follows is simple: the first two categories go on a page and on your business listing; the third goes on a dated channel — a post, a message, a story — that nobody expects to remain true.
It is also the only way to keep the promise. A shopkeeper who publishes daily what changes and never what does not works hard for a mediocre result; the reverse takes half a day a year and a few minutes a day.
"Do you have any" is your first channel
The most-asked question of a food shop is not a price, it is availability. "Do you have any…" arrives by telephone, by message, and sometimes as somebody who travelled for nothing.
That flow is an invisible cost: it occupies somebody exactly when the till is busy, and it costs the customer a call or a journey. It is also free information about what your neighbourhood wants and you do not carry.
The first fix is to write it down. A sheet of paper next to the phone for a fortnight, one mark per request. It produces a list of wanted products that experience alone would not have given you, and it costs nothing.
The second is answering the frequent cases in advance. If three people a day ask for the same thing, write it once: where it is, when your delivery comes, and what you offer when there is none.
The third is committing to a short channel. Many shops already reply by message and that is fine; what is missing is not the tool but the hours you answer, written down somewhere, so the customer knows whether to wait or to travel.
Out of stock: what to say when you do not have it
A stock-out is not a commercial failure, it is a normal event in a flow business. What costs money is not the absence of the product, it is how it gets discovered.
The worst case is the wasted journey, and it is nearly always avoidable. A customer who learns on the phone that there is none comes back tomorrow; one who learns it in front of an empty shelf goes elsewhere and stays there.
The wording that works has three elements and not one more: what is missing, when your delivery comes, and what you offer instead. The third is the most important and it is the one that gets left out.
You also need to be able to say no permanently. A product you no longer stock has to be announced as such, otherwise you will get the same question for a year and disappoint the same person repeatedly.
Finally, a practice that pays more than it costs: offering to let them know. A customer who leaves a number to be called when stock arrives is a customer who comes back for certain, and it is the only customer list a food shop builds naturally.
Price display, on the shelf and online
A displayed price is an obligation in store and a decision online, and the two meet on one point: what is displayed has to be what is charged.
The gap between the label and the till is this trade’s leading source of conflict and the most destructive, because it is experienced as deception even when it is a label somebody forgot to change.
The fix is organisational: one person, a fixed moment in the week, and a simple rule — where there is a discrepancy, the lower price applies. That rule costs a few dinars and avoids an argument that costs a customer.
Online, the rule is to publish a price only if it is honoured and dated. A price published without a date is an indefinite promise, and a promotion whose end is not written keeps being demanded three weeks later.
There is a useful exception: the few known lines from the first section. Those deserve to be displayed, updated and dated — because they are exactly what people compare before choosing a shop.
Where people look for you, and when
This trade is searched for in a particular context: on foot, often in the evening, often to find out whether you are still open.
The internet market observatory published by ARPCE counts, for the second quarter of 2025, some 59.10 million internet subscriptions in Algeria, of which 88.71% are mobile and 11.29% fixed.
The most profitable consequence in this entire article fits on one line: your real hours, on your business listing, including Fridays, public holidays and Ramadan. It is free, it takes twenty minutes, and it is wrong in a surprising share of shops.
The second is the map pin. A neighbourhood shop that is not exactly where the map says loses customers who were a hundred metres away, and it will never know it lost them.
The third is a number callable in one gesture, because "do you have any" and "are you open" are the same two calls, and each is worth a journey.

Promotions: the ones that bring people in and the ones that cost
A promotion can do three different things and only one is profitable: bring in somebody who would not have come, make somebody who was coming anyway buy more, or give a discount to somebody who would have paid full price.
The third is the commonest and the only one nobody notices. It happens every time a promotion falls on a product your regulars already buy every week.
The rule that follows is counter-intuitive: a useful promotion falls on what people do not yet buy from you, or on a time when your shop is empty. On your best sellers at peak hours it is margin given away for nothing.
The second rule is the date. A promotion with no written end date becomes a price, and putting a price back up is infinitely harder than letting a promotion expire.
The third is quantity. "While stocks last" is an empty formula; announcing the real number, when you know it, turns a disappointment into information and protects you from the reproach.
Delivery, and why it is different here
Food delivery has almost nothing in common with delivering a parcel. The window is short, the goods are fragile, the cold chain is a constraint, and the customer is waiting at home in an hour they set aside.
So the first decision is the radius, not the price. Delivering a neighbourhood you can get back from in ten minutes is a profitable operation; delivering across the city turns a grocery basket into a losing errand.
The second is substitution. A missing item in a food order happens every day, and the rule has to be decided in advance: replace with agreement by message, replace automatically with an equivalent, or remove and deduct. All three are acceptable; having no rule is not.
The third is the slot. A slot announced broadly — "during the day" — is experienced as house arrest, and it produces failed deliveries that cost the entire margin on the basket.
The fourth is the cold chain, and it is not negotiable. Fresh goods delivered warm are a health problem before they are a commercial one, and it is the one point in this article where we would tell you to abandon the idea rather than do it halfway.
What can be measured in a shop
Three measures are enough and they need no software. The first is the list of products asked for that you did not have, kept for a fortnight. It is the most directly profitable number in this trade.
The second is footfall by hour, counted by hand for a week. It says where to place a promotion, when to add a till, and above all which hours are empty — which memory always estimates badly.
The third is the number of discrepancies between the label and the till, recorded by your cashiers. A shop with several a day has an organisational problem costing it customers without a single complaint.
What we will not give you: price, margin or consumption figures "observed in Algeria". We know of no dated series we could cite, and a price quoted in an article that will still be online next year would be exactly the mistake described at the start of this text.
What also cannot be measured: the people who walked past without coming in. No method available to a shop captures it, and an agency claiming to quantify it is selling you an estimate dressed as data.
Payment, the queue and the till
In this trade the queue is part of the product. A customer who finds everything they wanted and waits a quarter of an hour at the till remembers the wait, not the range.
Electronic payment is usually presented as modernisation; in a shop its value is more down to earth: it removes the hunt for change, which is the main source of slowness at the till during peak hours.
The direction of the market is dated: the average online transaction went from about 1,180 dinars in 2020 to nearly 5,400 in 2025. That figure concerns online purchases, but it says something broader — card payment has stopped being reserved for small amounts.
For a food shop the practical consequence is modest and real: accepting cards attracts no new customers, but it shortens the queue and removes the refused sale for want of change, which is a clean loss and humiliating for both parties.
What does need writing down is what you accept. A customer who discovers at the till that cards do not work does not try again; writing it at the door and on your business listing costs one sentence.

What to check before signing with a supplier
The first question sorts them immediately: ask who will update the catalogue and how often. If they have no precise answer, they are selling you a page that will lie in three weeks and that you will pay for over two years.
The second is about prices: will they publish only the stable, dated lines rather than the whole range? A supplier insisting on putting everything online has not understood how perishable your information is.
The third is about the business listing: is it in your name, with a shop email address, and who is responsible for correcting the holiday hours on it? It is this sector’s first point of contact and it is often delegated and then forgotten.
The fourth is about photographs: were they taken in your shop? A food business illustrated with generic aisle imagery is spotted at once and loses the one thing it had to prove, which is that it exists and is clean.
The fifth is a test: ask them to write what they would do when you are out of stock. If they propose hiding it, they are working against you; the right answer says what is missing, when the delivery comes, and what you offer instead.
What we do, and what we will refuse to do
What we will refuse: putting your full range online with prices. That would be billing you for a page that will be wrong in three weeks, and a page that is wrong about a price does more harm than a page that does not exist.
We will also refuse generic aisle photography. In this trade the only thing an image has to prove is that your shop exists, that it is clean, and that it looks like what will be there when somebody pushes the door.
A limit of competence, stated plainly: we are neither buyers nor range consultants. We will not tell you what to stock, and the list of wanted products you did not have is work you do better than we could in a fortnight.
What we do: the sorting between what does not move, what moves slowly and what changes daily; an accurate business listing with the holiday hours; the few known prices, dated; a written stock-out rule; and what you accept at the till, written before the till.
And what you should do without us this week: put a sheet of paper next to the phone and record every "do you have any". A fortnight. That list is worth more than anything we could sell you this quarter, and it costs nothing.
Frequently asked questions
Should we put our whole catalogue online?
No. Your stock and prices will be wrong in three weeks, and a page that lies about a price does more harm than an absent one. Publish what does not move — departments, services, hours — and the few known prices, dated.
Which prices are worth displaying?
The few lines your customers buy every week and know by heart. They are the only ones people search for and check, and they decide your reputation for price on everything else.
What should we say when we are out of stock?
Three things and not one more: what is missing, when your delivery comes, and what you offer instead. The third is the most important and the one that gets left out.
Do our promotions actually work?
A promotion on your best sellers at peak hours is margin given to people who were coming anyway. Put it on what your customers do not yet buy from you, or on the hours when the shop is empty.
Should we deliver?
Within a radius you can get back from in ten minutes, with a narrow slot, a written substitution rule and the cold chain respected. On that last point, better to abandon the idea than to do it halfway.
Where do we start if we do only one thing?
Correct your real hours on your business listing, holidays and Ramadan included, and check the map pin is on your door. Twenty minutes, free, and wrong in a surprising share of shops.
Where we come in
Two weeks of questions noted at the till and on the phone give you what people come to you for. Almost all of it is a matter of hours or availability.
- We separate the standing lines, the slow ones and what changes daily.
- We publish the real hours, including the days you close early.
- We photograph your own shelves, never a generic aisle.
Publishing your whole range with prices would have competitors tracking you and you correcting endlessly: we will not do it.
