In legal tech, a calculator that simply outputs a date isn’t enough. For law firms and legal professionals, a calculation must be consistent, auditable, and defensible. Over the past week, I’ve focused on refining the backend of our platform to ensure exactly that.

Modular Calculators That Adapt

Legal deadlines vary by jurisdiction, case type, and sometimes even by the type of claim. To handle this complexity, our calculators are now fully modular. Each one adapts to its specific rules without requiring changes to the core engine.

Why it matters: This modularity allows the system to scale efficiently, maintain consistency across multiple scenarios, and simplify testing and auditing.

Traceable Audit Trails

Every calculation produces a persistent record of how the outcome was derived. This includes the decisions applied, the sequence of rules evaluated, and the final result.

Why it matters: Audit trails aren’t just nice to have — they make calculations defensible. Lawyers can confidently rely on the system knowing there’s a clear, queryable record for review or compliance purposes.

Explicit Discovery Logic

Edge cases, like the timing of claim awareness in medical or legal malpractice, can dramatically impact deadlines. Our system now formally incorporates discovery rules, ensuring that all such considerations are applied consistently.

Why it matters: Encoding discovery logic explicitly eliminates ambiguity and protects against inadvertent errors in sensitive cases.

Narrative-Ready Output

Calculators don’t just produce deadlines — they produce structured outputs that can be translated into clear, client-facing explanations. Users can understand not just what the deadline is, but why it applies.

Why it matters: Clear narratives help lawyers communicate effectively with clients and support decision-making grounded in defensible logic.

Final Thought

The difference between a working legal calculator and a defensible one is enormous. This backend doesn’t just calculate deadlines — it remembers, explains, and protects, ensuring every outcome is reliable and traceable.
