Connectors
Connect your business.
Install a connector next to your system. It reads your data, sends it securely to A4G, and you start working in the A4G app.
Subiekt GT
InsERTAvailableA4G Connect for Windows reads your Subiekt GT database (read-only) and keeps A4G up to date: sales with margins, customers, products, warehouses and stock.

From download to your first numbers
- 01Download
Download the ZIP above on the computer with Subiekt GT or one that can reach its SQL Server.
- 02Install
Run Setup.exe as administrator. The wizard installs the A4G Connect service and sets up a read-only SQL login for it.
- 03Sign in or create an account
In the installer (Polish) click „Zaloguj się" (sign in), or „Zarejestruj się" (create account) if you are new: confirm your e-mail, name your company — the installer continues on its own. Then choose the Subiekt database.
- 04Open A4G
Open app.a4g.io. The first synchronisation starts a minute after installation; history appears as it arrives.
You create it in the installer — an account without a connected system would show nothing. Click „Zarejestruj się" (create account), confirm the e-mail we send you, and enter your company name; you become its owner. Colleagues are invited later from app.a4g.io.
