Read moreAbout these tools
Each tool handles a common, repetitive task in a law office. They are intentionally simple, work offline once loaded and do not store your data. They are not a substitute for professional judgment: deadline calculations in particular must be checked against the rules that apply to your case.
When to move beyond free tools
Free calculators help with one-off tasks. When a firm needs the same calculation on every matter, it is usually time for practice management software that records time automatically, generates invoices from it and calendars deadlines against each case. That is what EvidenceDesk does.
