I ran into the exact same confusion when I was comparing dev quotes for a small platform rebuild. One team was super cheap but couldn’t explain scope, another was quoting like we were building the next NASA system. What helped was looking less at price and more at how they break down work + handle changes mid-project. A colleague suggested I check B2B digital transformation services and honestly, their way of structuring projects made it easier to compare apples to apples instead of guessing.
