Need Expert Advice on Choosing the Right Software Development Services

I’m looking for some genuine guidance on how to choose the right software development services for a growing business. There are so many companies offering custom solutions, mobile apps, web platforms, and backend systems, but it’s hard to know which one actually delivers quality. What key factors should I consider before hiring a team? Should I look at past projects, tech stack, communication, or long-term support? Also, how important is it to choose a service that understands my industry? If anyone has personal experience or recommendations, please share your insights so I can make a confident and informed decision.
