Who has encountered automated testing? There are questions

[BatBoy]

I'm trying to establish processes, and I'm thinking of implementing automated tests to avoid wasting time on routine. I want to understand whether it is worth contacting an automation testing company or whether I can build something myself at the start. Who has been through this - can you tell me how it went for you?

I started out similarly - at first we tried to set up something on our knees, but quickly realized that it was not economical at all. It took a lot of time, and the result was so poor. Then we turned to an automation testing company and they did everything right, you can see that the guys are in the know. Fewer bugs, faster releases, and in general you work more smoothly.
