Subjects

From Subjects → New subject, fill in:

• Name — e.g. “GCSE Maths”, “A-Level Chemistry”, “Beginner Piano”.
• Level — GCSE, A-Level, or Other (used for grouping on the dashboard and student records).
• Hourly rate — the default that flows through to every lesson booked under this subject.
• Default duration — typical lesson length (most tutors use 60 minutes). Override per lesson.

When you stop offering a subject, archive it rather than deleting. Archiving:

• Removes it from the new-lesson dropdown so you can't accidentally book against it.
• Leaves historical lessons and invoices untouched — your audit trail stays clean.
• Is reversible — un-archive any time.

There's no hard delete for subjects, by design. You can't retroactively erase a subject from invoices that have already gone to parents.

When you put your prices up, open the subject and edit the hourly rate. If future already-booked lessons exist at the old rate, we'll ask whether you want to re-price them too.

The confirmation dialog shows you exactly how many lessons would be re-priced, the old rate and the new rate, before you commit. Past confirmed lessons stay at their original rate either way — we never rewrite invoices that have already been issued.

When you book a lesson, the subject's hourly rate is filled in for you. You can type a different number on the lesson form for a one-off discount or top-up, and that override is what shows up on the invoice. Past lessons keep whatever rate they were booked at — the lesson record carries its own copy of the rate.
