Already use Fastbooks?

Open Fastbooks from the Windows Start menu.

Open the installed application. Fastbooks restores an existing session where possible; otherwise sign in with the account connected to the business.

Reinstalling normally leaves separately stored business data unchanged. Keep a verified backup before recovery, migration or device replacement.
Continue where you work
Windows

Start menu → Fastbooks → Continue or sign in

The installed app is the normal main-computer interface. Additional device access appears only when it is available and configured inside Fastbooks.

When something changed

Use recovery only when normal account access does not work.

Ordinary reopening should restore the existing session or ask for the connected account. Recovery actions are for missing business data, a moved folder, a replaced computer or a verified backup restore.

Business opens normally

Continue with the restored session or sign in with the account already connected to the business.

Business folder moved

Use the application recovery screen to locate the existing business folder instead of creating a replacement business.

Computer replaced

Install Fastbooks, sign in and restore a verified backup rather than creating a blank replacement business.
