Billing

Bill a customer in seconds

One clear screen for the cashier: products on the left, the bill in the middle, payment on the right. It works the same with a USB barcode scanner, a mouse or a touch screen.

  • Scan barcodes or tap quick product buttons; search by name or code
  • Change quantity or price, add a note to any line (e.g. 1 year warranty, gift wrap)
  • Cash with quick notes (1 · 5 · 10 · 20 · 50 OMR) and automatic change
  • Keyboard shortcuts: F1 cash, F2 card, F3 due, F8 sales
  • VAT 5% calculated on every line; prints a tax invoice at once
  • Compact layout for 1024×768 POS terminals with on-screen keyboard

Receipts & WhatsApp

Design your receipt once and every sale prints the same way. Send the bill to the customer’s WhatsApp as a PDF, straight from the till.

  • Receipt designer with live preview: 80mm, 58mm or A4 tax invoice
  • Your logo, shop name in English and Arabic, VATIN, CR number, header and footer lines
  • Invoice barcode on every receipt — scan it later for returns or reprints

Due book

Sell on credit — and get paid on time

Write the bill to the customer’s due book with a pay-by date. On that day GPOS reminds you, and one tap sends the customer a polite WhatsApp reminder with how to pay.

  • Sell on due by phone number; new customers are created automatically
  • Take a part payment now, the rest goes to the due book
  • Choose the pay-by date (3 days, 1 week, 1 month or any day)
  • Dashboard reminder: “2 customers should pay today” with a WhatsApp button
  • Reminder includes the amount, the date and your payment number / bank / QR code
  • Due statement PDF for every customer; late, today and upcoming at a glance
  • Also on the website: see who owes, set dates and remind from your phone

Customers

Know your customers, reward them

Keep every customer with their phone number. Loyalty points are earned on each purchase and can be used as a discount on the next bill.

  • Find customers by name or phone; add a new one in seconds
  • Loyalty points earned automatically, redeemed at the till
  • Customer name and phone printed on the receipt and used for WhatsApp
  • Each customer’s due history: sales, payments and returns
Customers and loyalty points
Returns

Returns without mistakes

Scan the barcode on the receipt, choose what comes back, and GPOS does the rest: stock goes back, the money is refunded or taken off the customer’s due.

  • Find the sale by scanning the receipt or typing the invoice number
  • Return part of a bill; GPOS never allows more than was sold
  • Refund from the cash drawer or take it off the due
  • Admin PIN required, with the reason recorded
Return items from an invoice
Cash & services

Every riyal in the drawer is explained

Payouts and service work are recorded separately from sales, so the end-of-day cash always matches.

  • Cash payouts (supplier, expenses) with reason and admin PIN
  • Service charges for repairs and labour — mobile, computer, printer…
  • Expected cash in drawer = cash sales + due collected − payouts − refunds
  • Service jobs report as PDF
Cash payout
Inventory

Stock that is always right

Every sale, return and purchase updates the stock. Products have English and Arabic names, their own VAT, a cost price and expiry dates.

  • Products with barcode, English & Arabic name, category, cost and selling price
  • Manufacture and expiry dates with warnings before products expire
  • Unknown barcode? Its name is suggested from the GPOS shared barcode list
  • Import and export the whole list with CSV (Excel)
  • Low-stock and soon-to-expire lists on the online dashboard
Inventory
Purchases & suppliers

Buy stock, pay suppliers, know what you owe

Scan the goods as they arrive and the stock is updated in one go. Pay the supplier now or later — GPOS keeps every supplier’s account, and the owner sees it on the website too.

  • Supplier, bill number and items scanned with the barcode scanner
  • Pay now from the cash drawer (counted as a payout) or from the bank / owner
  • Not paid in full? The rest is kept as owed to the supplier
  • Suppliers list: bought, paid and what you still owe each one — pay part or all later
  • Every bill and payment on the website: Suppliers page with items and history
  • Purchase PDF with paid and still-owed amounts
What you owe each supplier
Barcode labels

Print your own price stickers

Choose products, choose the label size and print barcode stickers with name and price on any label printer.

  • Many label sizes (e.g. 50×30, 40×25, 38×25 mm)
  • Show or hide the price and the shop name
  • Live label preview before printing
Barcode labels
Reports

Clear numbers for the owner

See today, the last days, the month or the year: sales, invoices, VAT, returns, payouts, dues and the cash that should be in the drawer.

  • Filter by period and by branch
  • Search any invoice by number, product, amount, date or cashier — and reprint it
  • Due summary: sold on due, collected, still owed
  • Export to PDF and CSV
Sales & reports
Branches & staff

Many branches, one owner

Each branch logs in with its own email and PIN, and its sales stay separate. Cashiers get their own PIN; sensitive actions need the admin.

  • Branches with their own login, address and phone
  • Staff users with roles (cashier, manager) and 4-digit PINs
  • Admin approval for price changes, returns and payouts
  • Owner sees all branches together or one by one
Branches
Hardware

Works with your shop equipment

GPOS talks directly to thermal printers, the cash drawer and customer displays.

  • USB or network thermal printers (80mm / 58mm) and normal A4 printers
  • Cash drawer opens on cash sales
  • Second screen customer display showing the order and total
  • Small pole display (VFD / LED) on a COM port
Printer settings
Invoice designs

Invoices that look like your brand

Pick a design once — every printed bill, PDF and WhatsApp invoice uses it, on the shop computer and on the phone. Your logo is printed faintly behind the invoice.

  • Receipt roll (80 / 58 mm): Classic, Bold, Compact and Boxed designs
  • A5 and A4 pages: Modern, Classic, Bold, Minimal and Elegant, with page borders and fonts
  • Any colour you like — or the same colour as the app
  • Your logo faintly in the background of A4 / A5 invoices
  • On the phone: choose the design and the colour in Menu → Printer, with a live picture of each design
  • Phone bills print on a Bluetooth or Wi-Fi receipt printer, or as an A4 / A5 PDF
A4 Modern — your colour and logo
Look & feel

Light, night — in your own colour

One tap at the top of the screen changes the whole app: light or night mode, and the main colour you like best. Your shop logo sits softly in the background so every screen feels like your own.

  • Light, night or the same as the computer
  • 9 main colours on the computer, 10 on the phone — blue, green, red, pink, purple…
  • Invoices can use the same colour (one switch)
  • Logo in the background of every screen and of A4 / A5 invoices
  • On the phone: a colour button on the Home screen — the choice is remembered
The colour menu at the top of the screen
Offers & QR orders

Offer posters that bring orders

Pick the items, choose the discount and GPOS draws a ready poster with your logo, prices and the last day. Print it, post it on WhatsApp Status, or send it to your customers one by one. A QR code on the poster opens your own order page — customers choose items and order, and you are told at once.

  • Pick items (or scan them), apply −10 / −15 / −20 / −25% or type each offer price
  • Upload an item photo with one tap — it shows on the poster
  • 3 designs (Big sale, Clean grid, Eid / Ramadan) in Post and WhatsApp Status sizes, English + Arabic title
  • A QR code “Scan to order” on every poster opens your order page: offers first, then all your other items
  • The order arrives in GPOS with a ringtone you choose; reply to the customer on WhatsApp in one tap
  • Offer prices work at the till on the days of the offer, and the poster prints on A4 for the shop window

Service & repairs

Receive an item, give a slip, follow the job

For mobile, computer and printer repair shops: write down what came in, with photos, and give the customer a slip with a job number and barcode. Scan the barcode later to open the job and make the bill.

  • Receive on the computer or on the phone — phone jobs appear on the computer within seconds
  • The customer slip prints at once on the phone’s printer or on the shop computer’s printer
  • Item, problem, service type, estimate, what came with it (bag, charger…) and photos
  • Steps: Received → Pending → Ready → Delivered (or Returned) — and a WhatsApp message to the customer at each step
  • Item sticker with the job barcode on your label printer
Service & Repairs on the computer
IP cameras

A picture of every paid order, in your e-mail

Connect your shop camera and GPOS takes a picture the moment an order is paid, then e-mails it to you with the bill number, the cashier, the items and the total. The cash drawer and printing are never delayed.

  • Works with Hikvision and Dahua cameras — only the IP, user and password are needed
  • “Find cameras on my network” finds the camera by itself; you type only the password
  • Press Test to see a picture at once
  • No internet? The order waits and the e-mail goes out later
  • Locked with the admin password
