Acrux Advisory is not a CPA firm and does not provide services that require a license to practice public accountancy. All services are limited to advisory, bookkeeping, accounting operations, financial reporting, and controller-level support permitted under applicable law. We do not provide audit, attest, assurance, or tax services that require licensure. Availability of services may vary, and engagements are accepted based on current capacity. Acrux Advisory reserves the right to decline or postpone an engagement if, in our professional judgment, the company’s records require significant cleanup or foundational work before audit readiness services can be provided — and in such cases, audit readiness support cannot be offered until those conditions are met.
