That's true. But a web interface has the advantage, that the ledger can
be used from anywhere. Even restricted user accounts can be given to
business partners. So they can see their own account. For a small
association, where I am the financial administrator, our bookkeeper
wrote such an small ledger in Apache+PHP+Postgres. Each member can look
into his own account and into the consolidated profit+loss, even can
change some of the own data like address, email etc. And he can see the
original document/check of his payment - just one click away. It's
paperless.
The disadvantage is, that strokes from the keyboard cannot be supported
easily by an web interface. The same is true for some context dependent
logic and data.
You need both: a webinterface and a GUI-client with local logic.

Interface layers?
You can see a database as a storage interface. Users like to use their
own favorite database system like Postgres, MySQL or Oracle.
Exchangebility is a good design principle.
