"The company will upgrade its computer information systems next month" vs "The company will upgrade their computer information systems next month"

Since the word "company" is singular, it goes with the singular possessive pronoun "its," not "their." This is a very common error; you often see incorrectly formed sentences like "The restaurant paid their employees."

Last Updated: December 10, 2017

The company will upgrade its computer information systems next month

This is correct

This sentence is correct in structure and syntax.

Some examples from our editors:

  • The company will upgrade its computer information systems next month, so please delete any unnecessary files.

Some alternatives from our editors:

  • Next month, the company will upgrade its computer information systems.
  • The company is going to upgrade its computer information systems next month.

The company will upgrade their computer information systems next month

This is not correct. Don't use this phrase.

The only way that this sentence could work would be if this company was upgrading systems that belonged to a separate group of people, for example: "The company will upgrade the executives' computer information systems next month. The company will upgrade their information systems next month." But if the company is upgrading its own information systems, the word "its," not "their," must be used, because the word "its" is singular while "their" is plural.
