Run the EXE on one office computer and let other users work locally or across the LAN from their browsers.
A business can keep one installed company server while several authorised users work from browsers on the same trusted office network.
In product validationServe the authenticated FataFat web app from the installed EXE so office laptops can use it without installing the software everywhere.
Every office laptop no longer needs a separate desktop installation or a separate copy of company data.
With Fastbooks
The controlled result
The EXE remains the sole company authority while local and LAN browsers use the same data with their own sign-ins and permissions.
Demonstration sequence
Show the workflow from evidence to outcome.
A feature page should make the user action, product transformation, review decision and accounting consequence visible in order.
1
Enable browser serving and trusted private-network access in the EXE
2
Restart the desktop app and copy the office browser URL
3
Open the URL from another laptop on the same network
4
Sign in with separate users and verify shared company updates
End on the retained accounting or review outcome, not on a decorative success screen.
Evidence gate
What must be proven before broad advertising.
Implementation is not the same as commercial proof. These checks define what representative validation must support.
Local browser and office LAN browser access from the packaged EXE
Separate authenticated users and company permissions
No second company authority or duplicated local database
Private-network-only deployment guidance and firewall validation
Fastbooks product doctrine
Prepare intelligently. Review explicitly. Keep one accounting authority.
Fastbooks may capture, classify and prepare work from different sources. Official numbering, posting, correction, reversal and reporting must still pass through the existing canonical owners and permission boundaries.
