We sell LawyerOS, a Notion template; the free tools above are separate and need no purchase.
How the calculators work
Each calculator turns the figures you enter into a result you can check by hand; the maths is explained on its own page. Results depend on your inputs and on vendor prices you should confirm yourself, so treat them as planning aids, not quotes or advice.
What these tools do not do
- They do not calculate court deadlines or limitation periods.
- They do not hold or move client money.
- They do not replace professional or financial advice.
- They do not connect to your Notion workspace or any other account.
For regulated functions, use software designed for them and check your own regulator's rules.
