How we help.
Monthly accounting and financial reporting for small law offices
Where the office already has a bookkeeper, the work is arranged around the books that person keeps. Brent works in the software you already use, or recommends a setup if you don’t have one.
The state’s trust account rules
Money a law firm holds for clients — retainers not yet earned, settlement proceeds, funds held for a transaction — is not the firm’s money. The attorney remains responsible for the trust account under the rules.
