General
Does the program need internet?
No. It works completely offline. Your data lives in files on your own PC.
Is there a monthly subscription?
No. Try it free for 7 days, then it's a one-time license for the machine.
Which Windows does it run on?
Windows 7 and up, 32 or 64-bit, with no complicated installation. Windows 8.1/10/11 need nothing extra; on Windows 7 install .NET Framework 4.8 once (free from Microsoft). It's light enough for older PCs.
Can I watch the shop from my phone while I'm away?
Yes (version 1.3). The program has a small built-in web server: open its address on your phone — on the shop Wi-Fi, or from anywhere after forwarding one port on the router — log in with the manager account and see today's sales, latest receipts, best sellers, low stock, expiring products, credit owed and the kitchen queue. View-only, refreshes by itself, and it can run over HTTPS with your own SSL certificate. The settings tab has one-click checks that tell you exactly what to fix (firewall, router…). Try the live demo with test / test.
Discounts, returns, shifts, tables, VAT — does it do those?
Yes, since 1.4 — all optional and off by default (Settings → Features): line/receipt discounts with a cashier limit and sale prices; partial returns with refunds; shifts with a float, cash in/out and a Z report; split cash+card; a VAT line; selling by weight with scale barcodes; sizes & add-ons; tables and held orders; product pictures; supplier invoices and expenses with net profit; daily automatic backup and a daily Telegram/e-mail summary.
Do products have expiry dates?
Yes (1.2). Each product can carry an expiry date; the inventory shows it, an “Expiring soon” tab lists what expires within 3–60 days, and the manager gets a red badge plus a once-a-day reminder.
Can I keep suppliers and clients?
Yes (1.2). One switch in Settings adds a Suppliers & clients page, a client button on the sale (the client is printed on the receipt) and a supplier button when receiving stock, with a deliveries history per supplier.
Arabic or English?
Both. Arabic is the default; switch in Settings → General.
Can I put my shop's name and logo on it?
Yes. Settings → General: brand name and logo. They appear on the window, receipts and labels.
How many products or receipts can it hold?
Practically unlimited for a small or medium shop.
Hardware
Which printers does it support?
Any thermal printer with a Windows driver, 58 or 80 mm. Pick it in Settings → Printer, then Tests → Test print.
Can it open the cash drawer?
Yes — through the printer (RJ11) or a COM port. The Tests tab has a diagnostic that tries every kick command.
Does it work with a barcode scanner?
Yes: scan to sell, and scan to receive stock. Any USB scanner that types like a keyboard.
Can I print barcode labels?
Yes — multiple sizes including pharmacy split labels and 3-across rolls, and a print-all button.
Do I need a touch screen?
No. It's designed for touch, but works perfectly with a mouse.
Selling
Does it have cashier accounts?
Yes: a manager plus cashiers, and every receipt records who sold it. Since 2.0 you can grant or revoke any single right per cashier (reports, inventory, void, returns, expenses…); anything they lack still works with the manager's password.
Does it do the ETA e-receipt?
Yes, as an option in the Platinum package. Once your shop is enrolled in the e-receipt system, you open your taxpayer profile on the ETA portal, choose “Register ERP system”, type PosMasr and a validity period, and the portal gives you a client ID and secret on the spot — enter them in Settings, give each product its GS1 or EGS code, and every receipt is submitted automatically, queued when offline, and printed with the ETA QR code. No certified device and no USB token are needed for receipts; the electronic seal is used for enrolment and B2B e-invoices.
I don't have a barcode reader — can I still manage stock?
Yes. From the owner portal on your phone you can count a stock-take, add products and receive stock, scanning barcodes with the phone camera (Chrome on Android over HTTPS) or simply typing the code.
Can I bring my product list from Excel?
Yes — Settings → Products → Import (CSV). Export first to get the template, fill it in Excel, save as CSV UTF-8 and import; existing products update and blank cells keep their values. Colour/size variants, service charge, VAT with Egypt's 14% and A4 invoices are also there since 2.0.
Can the customer see the order on a screen of their own?
Yes, since 2.1 (Gold package or higher). Plug a second monitor into the till PC, set Windows to Extend, and tick Customer display in Settings → Features: the customer sees every line with quantity, price and total as it is rung up, the grand total, and after paying the amount paid and the change — like the screens at the big chains.
Can I sell wholesale and retail from the same till?
Yes, since 2.2 (Gold or higher): switch on Price levels, give products a wholesale price, and tap Retail / Wholesale before the sale — or mark a client as a wholesale client and the switch happens by itself.
Can the customer pay with InstaPay or a wallet?
Yes: save your account's QR as a picture, pick it in Settings → Features, and it shows on the customer display while the order is rung up (and on the receipt if you want). The customer scans it with their phone; the money goes straight to your account, the program just shows the code.
I have an older copy with products in it — do I type them again?
No. Since 2.3, Settings → Products → Import from an old copy finds older PosMasr / CSG POS copies on the PC (or you browse to the old products.txt) and brings over the new products and the changed prices from any version since 1.0. Your current products, cashiers, settings and sales are not touched.
Two tills in one shop?
Since 2.2: one primary and one secondary over the shop's network. The secondary gets the products, stock and clients from the primary and sends it every receipt; if the network drops the receipts queue and go through later. The second license is 40% off.
Does it support selling on credit?
Yes, with a who-owes screen, repayments, and printed statements per customer.
Does card payment connect to the bank terminal?
The Card button records the sale as paid by card and prints it on the receipt. Direct integration with a bank terminal depends on the bank and the machine model and isn't part of the program.
Is there a kitchen screen?
Yes — on the same PC or another PC over your Wi-Fi/LAN. See the kitchen screen page.
Data & license
Where is my data?
In plain text files in the data folder on your PC — never on the internet. You can even open them in Excel.
What if the computer breaks?
Use the built-in backup to a USB flash drive, then restore on the new PC — all or just the parts you choose.
How do I activate?
Settings → Tests → License status shows a machine code. Send it to us; we send back a key; type it in. Permanent, for that machine.
Can I move to a new PC later?
Yes — contact us for a key for the new machine and move your data with the backup.
