One installer, 155 MB

Installs and updates from the same file. No admin rights, no Java, no internet.

Install day, done properly

Business details, your admin password, the first backup, and a printed recovery sheet you keep in the drawer.

Your shop stays yours

The vendor account is claimed on install day and cannot be locked out. Your data lives on your computer.

Licensed to your machine

One licence per PC. Send the Installation ID, receive the licence file.

Does it need internet?

No. Everything runs on the shop computer. Email and WhatsApp receipts use the internet only when you choose to send one.

We already have stock in Excel.

Import it with a preview. Opening balances for customers come in the same way.

Can it run on more than one till?

Today it runs on one computer per shop. Multi-PC LAN mode is in testing with a client in Kaduna.

What if the PC is off for a month?

The ledger catches up with no day limit, and the missed backups run on the next launch.

What computer do we need?

Windows 10 or 11, 64-bit. A thermal printer if you want counter receipts.

How is it licensed?

One licence per computer, bound to that machine. No subscription.

Bring one month of your books.

I will enter a week of it in front of you and show the ledger balance. Then you decide.
