Which plan to pickA single business should weigh US$129 a month against the AI matching already built into Xero or QuickBooks. Bookkeeping firms should ask for the firm pricing, which is set per firm and adds multi-client management.Talk to your Thomson Reuters account manager, since price depends on your Westlaw contract. Ask for a trial on real matters and compare the full CoCounsel Legal tier with the cheaper Essentials bundle before you choose.There is one route in: book a demo and get a quote. Ask which modules you actually need, since many teams only need Negotiate to start.
