Features

Every screen in RKCoders POS and what you can actually do in it.

The core licence unlocks all of the following. ZATCA Phase 2, Delivery, Eyewear retail, Bahrain e-invoice and Loyalty are separate add-on modules.

Point of sale

The register itself, in either a touch-friendly Visual tile layout or a keyboard-driven Standard list.

Smart Visual item display: ticket lines first, then sales frequency, on Home and in a category
An unfinished ticket comes back after an accidental close — the selected items are still there
Closing the till asks for confirmation
Search by name, scan a barcode or key in a SKU
Line and whole-ticket discounts by percent or amount
Split a single sale across multiple payment types
Hold and resume parked tickets while you serve someone else
Void a line or a whole bill with a mandatory reason
Assign a customer, which switches the receipt to a tax invoice when they have a VAT number
Reprint receipts, export a PDF or email an invoice
Reads weighed-item barcodes printed by a shop scale, or a live weight from a serial or network scale
Items marked for a price change ask for the price when scanned, and Price on the pad edits that line

Dashboard

A single screen that tells you how trading is going right now.

Today's sales compared with yesterday, ticket count and average ticket
VAT collected and a seven-day sales trend
Sales by hour and the mix across payment types
Best-selling products, categories and cashiers
Low-stock warnings and store totals

Products and catalogue

Build and maintain the product list your till runs on.

Add, edit, duplicate and delete products
Nested category tree
SKU is the base barcode; extra pack sizes have their own code
Weighed items priced per unit of weight
Mark an item so its price can change when it is scanned
Per-product tax rate and product images
Import in bulk from Excel or CSV using the supplied template, with a results report
Export the catalogue back out again
Purchases: receive a supplier delivery, add stock, and refresh unit cost

Stock

Know what is on the shelf and what it is worth.

On-hand quantity and cost value per product
Qty or cost adjustment documents from Stock
Every movement records a reason: adjustment, stock count or purchase

Customers and suppliers

Kept in one place, on separate tabs.

Name, phone, email and free-text notes
Phone is the lookup key on a delivery call
Several Bahrain national addresses per customer (building, road, block, area)
Credit limit with on-account sales and collections
VAT number, commercial registration number and address
Adding a VAT number makes their sales print as standard tax invoices

Documents and audit log

Every sale the till has ever produced, searchable after the fact.

Filter by type: sale, void, return or credit
Filter by status, including open delivery runs, and by ZATCA submission state
Simulation filings are labelled Submitted (simulation)
Open any invoice to see its lines, payments and QR code
Void an invoice, print it, save a PDF or download the signed XML
Retry a failed ZATCA submission from the document itself
A separate audit tab lists every void with its reason and who did it

Delivery orders

A paid add-on for phone sales that leave with a driver. The cashier does every step; the driver does not log in.

Look up the caller by phone and confirm a Bahrain drop address before ringing items
Confirm items, print a pick slip, confirm picked, then hand the bag to a driver
Stock leaves the shelf when the run is sent, not when the call is taken
Settle cash, card or already paid when the driver reports back; the tax invoice is issued then
Failed runs put stock back if the bag already left

Eyewear retail

A paid add-on for optical and sunglasses shops. Windows and Android.

Sunglasses or accessory, with brand, model name, model number, colour code and size on the product
The product name can fill itself from those details
Search the till by model number, brand or colour as well as name and barcode
With included items: selling a pair also takes its case and cloth out of stock
Kit: an item with no stock of its own; selling one takes only its parts out of stock
Model details and included items print under the line on the bill
Voiding a bill puts back exactly what that sale took out, even if the bundle changed later
Eyewear sales report for today, this month or any range: bills, sunglasses sold, VAT, cost, profit, best sellers, brands, included items given and low stock

Reports

Printable numbers for the day, the month or the accountant.

Sales report over any date range
Stock valuation report
Full shift and end-of-day history
Print any report straight from the screen

Promotions

Simple, predictable discounting.

Percentage or fixed-amount promotions
Target a single product, a whole category, or both
Switch a promotion on and off without deleting it

Shifts and end of day

Cash accountability for every person on the register.

Open a shift with a counted opening float
Record cash paid in and paid out during the shift
Close with a denomination-by-denomination count and see the variance
End-of-day close covering all shifts
Printable shift and end-of-day reports

Tick exactly which of the ten screens each user may open
Deactivate a user without deleting their sales history

Hardware

We would rather tell you plainly what works and what does not.

Receipt printer
Supported

Any printer Windows can see. 58 mm and 80 mm print a receipt. A4 prints a full-page invoice. Print silently, print automatically after payment, and set copies and font size.
Barcode scanner
Supported

Standard USB keyboard-wedge scanners work with no configuration. The checkout search box accepts the scan directly.
Weighing scale labels
Supported

Barcodes printed by a shop scale are decoded into product and weight or price. You define the prefix and digit layout in Settings.
Cash drawer kick
Supported

Sends a RAW open pulse through the receipt printer. Choose an Epson, Star or custom hex command in Settings, and kick from the till button, after cash sales, or after every sale.
Customer-facing display
Supported

A second Windows monitor shows the ticket, totals and a thank-you screen. Configure it in Settings, or preview it on this PC if you only have one screen.
Serial or network scale
Supported

Read a live weight from a COM-port or TCP scale in Settings. When you add a weighed item, the till can fill the weight. Scale-printed barcode labels still work.
Pole display
Supported

A 2-line COM / USB-serial VFD shows the last item and the running total, then thank-you and change. Configure it under Settings → Customer display.

Modules
