2

Per-task pricing adds up quickly: On Demand plan at $50-$75 per task seems affordable, but analyzing 10 documents per month costs $500-$750 -- more than the $225/month CoCounsel Core subscription with unlimited similar tasks

3

Volume discount requirements: CoCounsel Core offers volume discounts, but these require multi-user commitments and annual contracts -- solo practitioners and small firms pay full price without negotiation leverage

4

Reference attorney fees: While All Access includes reference attorney support, individual consultations or extended research requests may incur additional billable hours beyond the base subscription

5

Contract term commitments: Westlaw Precision bundles require 1-year minimum contracts with no monthly option -- canceling early results in penalties or requiring payment of remaining contract months

6

Limited jurisdictional coverage on lower tiers: Basic Research and Core plans may not include full state-by-state case law access -- firms practicing in multiple jurisdictions must upgrade to All Access ($500/month) or Westlaw Precision bundle ($428/month)
