Building a new tool vs buying an existing tool is a frequent problem in technology companies. Engineers want to build, engineering management may think that their needs are unique, culture may reward builders rather than people saving. Generally you want to lean towards buy unless it is core to your business.
If you can’t find a solution to buy, consider why no one has built one. Either you have a new business idea or you have a problem not worth solving1.
