Count就是中文里数钱的数。在count这个动词后面加上er就变成了名词counter，也就是数数的人，bean counter（尤指大公司的）会计师；(对金钱)善于算计的人。

【例句】
It looked like the project was going to be approved, but the bean counters said it wasn't cost-effective.
眼看这个项目就要获批准了，但会计师们认为它不划算。

They are bean counters who tend to focus on controlling expenses.
他们是倾心控制支出的精明人。
