Why these, and not a blog
Reference material, organised by the work it belongs to.
Each item exists because it answers a question we were asked by a practising auditor more than once — and each is useful to a firm that never speaks to us. They are grouped by topic because that is how they get used: nobody reads one purchase testing reference in isolation.
None of it is authoritative. Standards and statutory rules change, and every page says so and tells you to check the current text before relying on it in a file.
Looking for a sample working paper?
Rather than a PDF, there is a complete worked example in the product — a revenue testing paper with its population, sample basis, procedures, exception schedule, tickmark legend and sign-off block, exactly as Lekhya produces it.
Something missing?
If there is a reference your team keeps rebuilding by hand, tell us. If it is useful to more than one firm, we will write it and publish it here without a form in front of it.
