**The short answer:** to open a supermarket or mini-market you pick a location with steady foot traffic, get the licences your local authority requires, fit out the space, buy a first range of fast-moving stock on credit terms where you can, set up a till that scans barcodes, and price every item from its real cost. Most of the money goes into stock and rent, not shelves. This guide lists the steps, what drives each cost, and how to avoid the mistakes that drain a new shop in its first months.

## The steps to open

1. **Choose the location.** Count the people who pass at the hours you will be open, not only the rent. A cheap street nobody walks down is the expensive choice.
2. **Check the licences.** Business registration, trade licence, health and food-handling rules, signage and fire rules differ by country and city. Ask your local authority or chamber of commerce what applies to a shop that sells food. This guide does not give legal advice.
3. **Fit out the space.** Shelves, a chilled section, a till counter, lighting and a storeroom.
4. **Open supplier accounts.** Wholesalers and distributors set their own minimum order and payment terms. Ask each one for its terms in writing.
5. **Buy the first stock** (see below).
6. **Set up the till and the item list** before opening day, so the first customer is scanned, not typed.
7. **Open quietly for a few days,** fix what you notice, then announce.

## What the money goes to

No two shops cost the same, so here are the categories and what moves each one, with no invented total:

- **Rent and deposit:** the street, the floor area and the lease length.
- **Fit-out:** how much shelving, how much chilled space, and whether you build or buy used.
- **First stock:** usually the largest item. It depends on the number of product lines you carry and how much of each you put on the shelf.
- **Equipment:** shelves, fridges and freezers, a barcode scanner, a receipt printer, a till device, and scales if you sell by weight. Chilled equipment also adds an electricity bill.
- **Staff:** opening hours multiplied by the number of people needed on the floor and at the till.
- **Running costs:** electricity, water, packaging, cleaning, bank or card fees.
- **A cash cushion** for the first months, when sales are still building.

Put your own quotes into the [break-even tool](/tools/break-even) to see how many sales a month cover your fixed costs.

## Choosing the first stock

Start with what people buy every week: staples, drinks, dairy, cleaning, and snacks. Add a second layer only after you see what sells. Short-dated food ties up cash if it stays on the shelf, so buy smaller amounts of fresh items more often. Keep one supplier price list per item in a sheet, for example the free [grocery price list template](/tools/templates/price-list/grocery) and the [grocery stock count sheet](/tools/templates/stock-count/grocery).

## Pricing and margin

Margin is the part of the price that is yours after the item's cost. Supermarkets run on thin margins: a 2023 Supermarket News article reporting a dunnhumby survey put grocers' actual average net profit margin at 2.5%. That is why small errors in pricing, waste and theft matter so much. Work out each price with the [margin calculator](/tools/margin-calculator), then check the month with the [profit tool](/tools/profit). Fresh items usually need a wider margin than packaged ones because some of them spoil.

## A daily routine

- **Morning:** count the cash in the drawer, check the chilled section, rotate short-dated items to the front.
- **During the day:** scan every sale. Items sold without a scan are stock that disappears from your records.
- **Evening:** close the till, compare the cash against the day's sales, list what is running low.
- **Weekly:** count one section of the shop and compare it with your records.

## Common mistakes

- Pricing from the shelf price at a rival instead of from your own cost.
- Buying too much of an item because the supplier offered a discount.
- Letting regular customers take goods on credit without writing it down.
- Skipping stock counts, so shortages show up only when cash runs out.
- Opening with too many product lines and too little cash left for the first weeks.

## A checklist

- [ ] Licences confirmed with the local authority
- [ ] Lease signed and fit-out priced
- [ ] Supplier terms in writing
- [ ] First stock list with cost and selling price per item
- [ ] Scanner, receipt printer and till tested
- [ ] Staff schedule for the first month
- [ ] Cash cushion set aside

## Where Dashing helps

Dashing has a barcode cashier that works offline, so a dropped connection does not stop a sale ([how it works offline](/blog/offline-cashier-how-it-works)). It keeps stock per item, records customer debts, supports stock counts and suggests what to reorder. The free plan covers one branch, with no end date. See [the supermarket and grocery page](/for/grocery), [scan with a camera or scanner](/help/scan-barcodes-camera-or-usb-scanner), [sell by weight](/help/sell-by-weight-scale-labels), [reorder suggestions](/help/reorder-suggestions) and [the free plan](/free).
