Issue with merging two databases

Hello,

I have an issue merging two databases.

Database 1 contains information on public procurements contracts (e.g. €-value of contract, activity of contract, winning company, etc.)
Database 2 contains company information (company name, number of employees, turnover, balance sheet, etc.)
Evidently, I want to merge both databases based on the name of the company.
The problem lies in the fact that the company name is not always consistent in both databases.

Examples Do you guys have any suggestions on how to deal with this?

Kind regards,

Willem
