Why this checklist matters
Buying Choosing an LLM Provider is rarely about one feature. Total cost, reliability, paperwork, and post-purchase support all affect whether the decision still feels smart weeks later.
A structured checklist creates accountability: every important concern becomes an explicit step. That is especially useful when sales pressure or information overload kicks in.
In Developer, small missed details often become expensive corrections. Completing this guide before commitment is usually cheaper than fixing a rushed purchase.
