- In business, 'factoring' is 'факторинг'. Do not confuse with the general noun.
Common Mistakes
- Using 'factor' as a synonym for simple 'reason' without the implication of being one of several contributory parts.
- Incorrect preposition: 'factor for' instead of 'factor in' (e.g., 'Cost is a major factor for our decision' is less idiomatic than '...factor in our decision').
