15. An ISA for LCE audit of a client that keeps its books in BookTrove

The International Standard on Auditing for Audits of Financial Statements of Less Complex Entities (ISA for LCE) is a separate standard for audits of less complex entities, effective for audits of financial statements for periods beginning on or after 15 December 2025. AuditTrove lets an audit be carried out under it: the working papers and programme show the Part of the standard each step serves, the presentation steps are covered once by GEN-12 and the disclosure checklist, and the report and letters use the standard's wording (Part 9: no key audit matters; no separate going concern section unless there is a material uncertainty).

The ISA for LCE cannot be used for listed or other public interest entities, and AuditTrove refuses it for them. For every other audit the applicability paper AC-4L asks about the prohibitions (Authority A.1), the group limits and the qualitative characteristics of a less complex entity (Authority A.2–A.9), and requires the partner to stand back. If the audit turns out to be more complex, the partner moves it to the ISAs before the report — the transition the standard requires. Check the local position before relying on it: the FRC of Nigeria published a notice on the adoption and implementation of the ISA for LCE in July 2025, and firms in Barbados should confirm ICAB's position.

Rumuola Marine Supplies Limited is an owner-managed supplier of ropes, lubricants, safety equipment and provisions to vessels in Port Harcourt. It keeps its books in BookTrove, TroveUniverse's bookkeeping app. With an auditor access token from the client, the team pulls the trial balance and the journal lines, sends proposed adjustments for the client to post, and sends document requests that the client answers inside BookTrove. Tamunoemi Briggs is the engagement partner and Ebiere Tariah the senior, in April 2026.

Use cases

• Use case — A small owner-managed company. Choose the ISA for LCE when you create the audit (step 15.2) and conclude on AC-4L (step 15.4).
• Use case — A client that becomes more complex during the audit. The partner moves the audit to the ISAs with a reason (step 15.17); every audit feature applies unchanged.
• Use case — A client on BookTrove. Ask for an auditor access token with the read, adjust and pbc permissions (step 15.6).
• Use case — The client accepts a proposed adjustment in BookTrove. Check BookTrove decisions (step 15.13): the adjustment becomes corrected, with BookTrove's entry number.
