Madar POS, step by step.

Before you start

Madar POS runs in a web browser, at your shop's own address. The address is in your welcome email and ends in madar-os.com, like yourshop.madar-os.com.

What you need

• A computer at each counter. A Windows PC with Microsoft Edge is best: the installer puts Madar on its desktop, and receipts print with no print window. Any computer, tablet or phone with a current browser also works.
• A USB barcode scanner that ends each scan with Enter. Almost every scanner does.
• A receipt printer for an 80 mm or 58 mm roll, set as the computer's default printer. A cash drawer plugs into the printer and opens when a receipt prints: turn on "open drawer" in the printer's own settings.
• Your card machine, as it is today. You take the card on it, and Madar records how much was paid by card.
• The internet. The cashier screen keeps selling without it, as below.

TipTo check a scanner, open Notepad and scan any item. The number should appear and the cursor should jump to the next line.

Without the internet

TipOpen the cashier screen once with the internet on, on each counter computer, so it can open without it later. Sales kept on a computer must reach Madar within three days.

Who does what

TipIn a small shop one person often sells and runs the shop. Make them a manager.

For the owner

From the welcome email to the first sale, then every day after.

First sign in

1. Open the email Your Madar POS is ready. It holds your sign in name.
2. Press Choose your password. The link works once, for 7 days.
3. On the page that opens, type a password of ten or more characters and press Save password.
4. The page says Your password is saved. Sign in with it. Type your sign in name and the new password, then press Sign in.
5. The setup of your shop opens: Set up Madar POS.

If the link has expired

1. Open the link anyway. The page says This link has expired or was already used.
2. Press Send me a new link. A new one goes to your email address. It can take a few minutes; check the spam folder too.
3. Nothing arrives? Write to support@madar-os.com.

TipIf the page does not open at all on a work network, the network may block the new address. Try on mobile data. See When something goes wrong.

Every day after that

Sign in at your shop's address. When the Madar assistant opens, press Madar POS in its side menu (on a phone, under More). Or open Madar POS from its own icon: see On the desktop.

Setting up

On Set up Madar POS, under Before the first sale:

1. Under Business name, as it goes on receipts, type the shop's name as customers know it.
2. Under Currency, choose the currency your prices are in, like OMR, Omani rial. For one not listed, choose Another currency and type Its three letter code. The currency is set once, before the first item.
3. Add your first branch: Branch name, and a Short code, on receipts of up to six letters or digits, like MB1.
4. Add its Address and Phone for the receipts. Leave Alert at (% of a full shelf) at 20, or change it.
5. Press Add the branch.

The dashboard opens with Finish setting up: add your items, give each cashier a login, and make the first sale at the counter. Each step ticks itself when it is done.

Then check Settings

• Your package. Under Branches, a line says which package you have, how many branches it covers and how many are set up, like Your package, Madar POS Grocery, covers 4 branches. 1 is set up.
• On every receipt. Type a VAT registration number only if the shop is VAT registered, and your own words under A line at the bottom. Press Save.
• Time zone. Madar takes it from your computer the first time you sign in. It decides when the shop's day begins. In Oman it should read Asia/Muscat. If you change it, press Save.

TipA shop that is not VAT registered leaves the VAT number empty and every item at 0% VAT. Its receipts then print as a receipt, not a tax invoice.

Adding items

1. Open Stock and press Add an item.
2. Type the Name, and the Name in Arabic if it has one.
3. Click Barcode and scan the item into it.
4. Type the Category, the Cost price and the Selling price: what the shelf says, VAT included. Choose VAT %, 0% or 5%.
5. Under Sold by, choose piece, or kg or g for items weighed at the cashier. Choose its Supplier.
6. For food with a use by date, tick Track expiry dates, or type a Shelf life in days: milk 7, bread 3.
7. Press Save.
8. Tap the item again, and set A full shelf and Alert me at (% of a full shelf) for this branch. Press Save.

TipA new item starts with nothing on the shelf. Record a delivery or a count to put its stock on. An item with no full shelf shows No full shelf and never alerts.

Importing a product list

1. Open Settings and find Import your product list.
2. Starting from nothing? Press Download the template. Its headings are in English and Arabic, with two TEST rows to delete.
3. Under Stock goes to, choose the branch first. The file's Stock column is today's stock there.
4. Under The file, choose an Excel workbook (.xlsx), a CSV file, a Word document (.docx), a PDF price list, or a database export (.sql) from your old system.
5. Read the preview. Each row says New, Changes, As it is or Not imported, and a value that changes shows what it was. When some rows need a look, tick the box like Only the 3 rows with something to check to see them alone.
6. If the file's stock is today's count, tick the box that begins Set today's stock at.
7. Press Import. The button says how many items, like Import 250 items.

Madar finds the table by its headings, in English or Arabic: Name and Price at least, and Barcode, Arabic name, Category, Unit, Cost, VAT, Supplier and Stock when they are there. It reads the file by rules and never sends it to an AI.

Importing again

• Items already in Madar are matched by barcode, then by name.
• Only what the file has a value for changes. A price list with just names and prices changes just the prices. An empty cell leaves the item as it is.
• When items at that branch have stock already, the stock box starts unticked, so today's stock stays as it is unless you tick it.
• A full shelf is set from the file only for items that have none, so the one you set stays.
• VAT from a file is used only when the shop has a VAT number in Settings.

TipAn old Excel file (.xls): open it in Excel, choose File, Save As, Excel Workbook (.xlsx), and upload that. A scanned page or a photo has no table to read: drop it in the Madar assistant's chat instead.

TipMadar POS Grocery holds up to 3,000 items. An import that would pass the limit is refused whole, so count your list first.

Suppliers

1. Open Suppliers and press Add a supplier.
2. Type the Name, the Contact person, the Phone, for calls and the WhatsApp, if different.

The Madar assistant

Only the owner has it. Press Madar assistant in the side menu and ask in your own words, for all branches or one:

• Sales, returns and profit for today, yesterday, the last 7 days, a month, or between two dates.
• What sold most, over up to a month.
• What is low or out, how much to order and from which supplier.
• Batches that expire soon, who owes the shop, and what the shop owes its suppliers.
• A supplier's order, written out for you to send.

It reads your figures and changes nothing: prices, stock and staff change in the admin portal. It never sends an order. Drop a scanned or photographed price list in the chat and it makes a spreadsheet for you to check and import. Its answers are written by AI and can be wrong, so check anything that matters. Your package includes a monthly allowance.

For a manager

You sign in with the name and password the owner gave you. The admin portal opens, for your branches only.

• Your branches. A branch manager sees one branch. An area manager picks a branch at the top of each page, or all of them on the dashboard.
• The owner's switches. What you can change follows What managers may do. Most buttons the owner has not given you are not shown. If you try a change you may not make, Madar says The owner has not given managers this. Ask the owner, or the owner can allow it in Settings. Without deliveries and counts, that page says The owner has not given managers deliveries and counts.
• Costs. Without the costs switch you see no cost prices, margins or profit. The dashboard shows the average sale instead.

To sell, press Open the cashier screen in the side menu, and Admin to come back. On the cashier screen you can also take returns (Return) and give discounts, as the owner allows. The steps are in For a cashier.

Only the owner changes the currency, the receipt, the time zone, the switches and managers' logins. Only the owner closes a branch or opens a closed one again. A manager of every branch who has the branches switch, Change alert points, full shelves and branches, can add a new branch, within the package. Managers do not have the Madar assistant.

TipTurn on alerts on your phone too: Alerts on your phone. Alerts are for the whole shop: your phone hears about every branch, not only yours, and most alerts name the branch.

For a cashier

A workplace network blocks the site

madar-os.com is a new address, and some office and school networks block new addresses in their first weeks. Use mobile data from a phone for now. The network's IT team can allow madar-os.com and *.madar-os.com. Madar needs HTTPS only. The security page has what they need.

Who to write to

Write to support@madar-os.com. Say the shop and the branch, what you pressed and what the screen said, and the receipt number if it is about a sale. A photo of the screen helps.
