Billing questions

What does Professional cover?

Professional currently creates monitored matters from eligible server-recomputed results in released supported jurisdictions. In England & Wales, that currently means CPR and Employment Tribunal results. A rule marked for verification or an unsupported workflow remains free to check, with its citation and working, but cannot become a paid record. The plan is for individual lawyers, barristers, clerks, paralegals and litigation professionals.

Why pay when calculation is free?

Free gives you the date, citation and calculation steps. Professional saves and monitors deadlines across your matters, with calendar feeds, recalculation history, rule-change warnings and exports.

What is a PDF calculation record?

The formal Evidence Record is a one-off PDF containing the inputs, result, rule ID and version, citation, calculation steps and generation time. It does not start a subscription.

No trial

No. The free calculator demonstrates the calculation itself without an account. Professional is charged when it begins and can be cancelled online any time.

How does billing currency work?

Choose from the currencies available for this plan. A calculator jurisdiction can suggest a familiar currency, but it never decides your billing country, tax treatment or plan. Stripe or Link confirms the currency, any applicable tax and the final total before payment.

How are taxes handled?

For Managed Payments purchases, Stripe, through Link, acts as merchant of record and handles sales tax, VAT and GST compliance where the transaction is covered. In locations outside that coverage, Thesmios Ltd may retain an indirect tax obligation. Checkout shows the applicable tax and final total before payment.
