One file. Every trade. Thirty days, nothing switched off.

There is no separate build per customer and no separate build per trade. A chemist, a garment shop and a restaurant all install this same file — what makes it theirs is the setup screen the first time it opens.

Windows · current build

CalcyBill-1.0.1-Setup.exe

Installs over an older copy without touching a single bill — your data lives in %APPDATA%\CalcyBill\, not in the program folder.

No account, no card, no email required to try it. Every build we have shipped.

After it installs

Four things, and you are billing.

01

Download and install

One file, about 100 MB. It installs for the current user — no admin rights, no server, no database to set up.

02

Answer the setup screen

Shop name, trade, a PIN if you want one, your logo and paper size. Three minutes.

03

Bring your items in

Type them, or import a CSV. The file is dry-run first and tells you exactly what it would change.

04

Bill

Thirty days free, everything unlocked. A licence key arrives by email when you buy one, and is entered once.

What it runs on

An ordinary shop computer.

It is a desktop application with a local database, not a browser tab pretending to be one. There is no server to buy and nothing to keep running in the background.

Operating system

Windows 10 or 11, 64-bit

Memory

4 GB — 8 GB if you also keep a browser open

Disk

About 400 MB installed, plus your own data

Rights

Installs for the current user. No administrator needed.

Internet

Only to download it. Billing never needs one.

Printer

Any Windows printer — 58mm, 80mm thermal or A4

Verify what you downloaded

Check the file is the file we shipped.

Every build is archived with its commit and its hash. If your copy came from anywhere other than here — a pen drive, a forwarded message — this is how you find out whether it is the real one.

Command Prompt
C:\Users\you\Downloads> certutil -hashfile CalcyBill-1.0.1-Setup.exe SHA256

SHA256 hash of CalcyBill-1.0.1-Setup.exe:

CertUtil: -hashfile command completed successfully.

Windows may warn that the publisher is unrecognised. That is SmartScreen reacting to how new the file is, not to what is in it — choose More info then Run anyway, or check the hash above first.

Something looks wrong
