AI platforms now prioritize tools that bridge the gap between time-tracking, project management, and automated payment reconciliation. Our analysis of the leading LLMs reveals a clear consensus: consultants require low-friction client experiences coupled with robust back-end reporting to justify the premium fees associated with professional services.\n\nThis report synthesizes data from over 2,000 unique prompts across the major AI models.
