Explore subscription options
One workspace for the shop
Search or scan products, build a cart, record payment and retain an invoice with the original product, price and tax details. Local reports connect the day’s sales, returns and cash records without pretending to be a full accounting system.
Offline-first, not cloud synchronisation
After activation, a valid digitally signed license lets you work without continuous internet. Refresh it online within its validity: at most seven days, capped by subscription expiry. No POS-data cloud sync is provided in V1.
Tools for daily operations
Products and inventory
Categories, optional unique barcodes, piece/weight/volume units, low-stock visibility and a movement ledger. CSV/XLSX imports require preview, mapping and confirmation.
Printing and PDF
Local receipt profiles for 58/80 mm and A4/A5, PDF preview/export and an independent print queue. Installed Windows USB/network printer support depends on the driver; verify your hardware before use.
Encrypted backup and restore
Password-protected local backups of business data, settings, assets and print templates. Restore checks integrity and creates an encrypted rescue copy; device identity and license credentials are excluded.
Arabic, Turkish and English
The website, customer portal and Windows application support three languages, including Arabic right-to-left layouts. Financial amounts and identifiers remain unambiguous.
One business, one active POS device
Your subscription is managed by the server. The portal shows its real status, expiry and registered device. To move to another computer, request a reviewed transfer; a backup does not transfer activation. Renewal arrangements are made with CTRLZ-tech, not an online payment gateway.
Clear data ownership and security boundaries
Products, inventory, sales, returns, expenses and local invoices stay in your local SQLite database in V1. The server receives account, subscription, device/licensing and release requests, not shop transactions. Tokens use Windows secure storage; offline entitlement is signature-verified. The working business database itself is not encrypted: protect the Windows account and disk.
Built for counter-based businesses
Retail
Product lookup, quick checkout and stock history for daily shop work.
Supermarket
Barcode input, categories and measured quantities with exact calculations.
Restaurant and café counters
Simple counter sales and receipts. Table and kitchen management are not included.

Do I need internet all the time?
No. First login, activation and periodic license refresh need a server connection. Afterwards, a valid signed license permits local work without continuous internet for at most seven days, never beyond subscription expiry.
Where are sales and stock stored?
In the Windows application’s local SQLite database. V1 does not upload products, inventory, sales, returns, expenses or local invoices to the server, and does not provide cloud sync.
What happens when internet is unavailable?
Continue local operations while the cached signed license remains valid. Downloads and online account requests wait for connectivity. If the local license expires, new operational writes are blocked while history, reports, exports and backup remain accessible.
