The expression is bean counters.

When I wrote the comment I had abacuses in mind. I'm not a native speaker so I didn't know about the bean counter idiom

That is actually pretty funny, you independently re-invented the expression.

As a native English speaker, I adore your version.

The "beans" way of thinking is outdated! If any company is to be successful in today's environment they need to be counting beads!

GP is still technically correct. Why would a bead counter count beans?

Everyone has to start somewhere
