Get up and running in 10 minutes

Fexl Lite is built so you can be ringing real sales the same hour you download it. This page is the fast track: six steps, ten minutes, ending with a printed receipt for your first product. Every step links out to a deeper page if you need it — but you can ignore those links on the first pass and come back later.

Have your license key ready

You’ll need the activation key from your purchase email at step 2. Find it now so you don’t have to dig for it mid-flow.

What you’ll need

• A Windows or macOS computer (any 5-year-old laptop is fine; we’re light)
• Your license key from the Fexl purchase email
• A receipt printer (optional but worth setting up — every sale prints a receipt by default)
• About 10 minutes

1

Install Fexl Lite

Download the installer from your purchase email and run it. The installer is small (~80 MB) and signed; Windows SmartScreen and macOS Gatekeeper accept it without quarantine.

• Windows — FexlLite-Setup-1.6.100.exe. Double-click and follow the prompts. Done in under a minute.
• macOS — FexlLite-1.6.100.dmg. Open and drag the app to Applications.

See Install on Windows or Install on macOS if anything trips up.

2

Activate your license

On first launch, Fexl Lite asks for your license key. Paste it from the purchase email and click Activate.

Activation talks to our license server once to verify the key, then runs offline forever. If your computer is offline at first launch, you can activate later from Settings → System → License.

ⓘ

One license = one device

Each license activates on one device. If you need to move Fexl Lite to another computer, deactivate from the old one first (Settings → System → License → Deactivate). The key works on any platform — Windows, macOS, web — but only one at a time.

3

Set up your store

After activation you land on the Store Setup screen. Fill in:

• Store name — appears on every receipt and invoice.
• Currency — IQD, USD, EUR, MXN, or any of 40+ supported. Default formatting follows the locale.
• Address & phone — printed on the receipt header.
• Tax ID / VAT number — if your country requires it on invoices.
• Logo (optional) — 200×200 PNG. Shown on receipts and invoices.

Click Save. You can edit any of this later from Settings → General.

4

Connect a receipt printer (optional)

Skip this if you don’t have one yet — Fexl Lite still rings sales without printing.

• USB ESC/POS printer (Epson, Star, generic 58mm/80mm) — plug it in. Fexl Lite detects it on launch and asks if you want to use it. Say yes.
• Network printer — go to Settings → Printer → Add and enter the IP. The wizard pings it and prints a test receipt.

If your printer prints a test receipt, you’re done. If not, see Troubleshooting → Printing issues — the cause is almost always the cable, the paper width, or the driver mode.

5

Add your first product

Open Products → Add Product. The minimum a sale needs is:

• Name — what shows in the cart.
• Price — what the customer pays.
• SKU or barcode — what you scan or search by.

Cost, supplier, category, variants, batches, serial numbers — all optional on day one. Add them as your inventory grows.

Click Save. The product is searchable in the POS instantly.

✦

Bulk-add products with a CSV

Already have your inventory in a spreadsheet? Use Products → Import → CSV to upload hundreds of products at once. The format is documented in the import wizard — name, price, SKU minimum.

6

Ring your first sale

Click POS in the sidebar. Your default cart is open. Three options:

• Tap the product card you just added.
• Type its name in the search box.
• Scan its barcode if you printed one.

The product lands in the cart. Click the green Checkout button, pick Cash, enter the amount the customer is paying, and hit Complete Sale.

If a printer is connected, the receipt prints. The journal posts. The cart resets. You’re live.

✦

That was the basic flow — there's a lot more

The five-second sale you just made is the core of every transaction in Fexl Lite. Everything else — split payments, customer accounts, returns, inventory tracking, reports — wraps around that same loop. See Ring a sale for the full POS reference.

Where to go next

You’re up and running. Here’s where most new users go in their first week:

SETUP

Finish store setup

5

Receipt template, payment methods, VAT, currency formatting — the rest of the configuration that wasn’t strictly required at first launch.

DEVICES

Add a second device

Pair a tablet, second register, or back-office computer to the same store. Sync keeps them all in lockstep.

INVENTORY

Set up inventory tracking

Choose tracking modes (quantity / serial / batch), add suppliers, generate barcodes, set low-stock alerts.

CUSTOMERS

Add customers + tabs

Capture customer details for marketing, debt tracking, and statements. On-the-fly creation works at the POS too.

PRINTERS

Configure receipt printers

USB or network ESC/POS, multi-printer setups for kitchen routing, label printers for product tags.

REPORTS

See what's happening

Daily report, sales by item, inventory valuation. The accounting reports work from day one — no setup.
