About Shim Book

Shim Book takes its name from the thin wedge used to level a joint. Side work often sits proud or low because hours and costs were guessed. We write about adding a thin shim — a clearer rate, a written limit, a weekly record — instead of stacking more jobs on an uneven week.

How we work

• We write practical guides with no earnings promises and no invented figures.
• Every piece is reviewed before it goes live and updated when rules change.
• We do not sell courses, lists or memberships. Everything here is free.

What we are not

We are not financial advisers, accountants or lawyers. For decisions with tax or employment impact, talk to a qualified professional.
