Assurance Engagements in Costa Rica

When a certification is not enough, a tailor-made report is required

In many banking, insurance, and corporate processes, the issue is not the lack of information, but the type of professional support provided. Generic reports, poorly defined scopes, or documents that fail to address what a risk analyst actually evaluates often lead to reprocessing, observations, or outright rejection.

Assurance Engagements performed by a Certified Public Accountant (CPA) are designed precisely to fill that gap: to provide solid, clear, and defensible professional support, tailored to the specific case and to the institution reviewing the report.

At JGutierrez Auditores Consultores S.A., we deliver custom-designed Assurance Engagements under the International Standard on Assurance Engagements 3000 (ISAE 3000 – Revised), with a clear focus on ensuring that the report works in practice, not just on paper.

Not a standard certification. A tailor-made solution.

Unlike Income Certifications, which follow predefined formats and scopes, an Assurance Engagement is not completed using a template.

Each engagement is designed around two key questions:

• What does the applicant need to demonstrate?
• What does the bank, insurer, or third party receiving the report need to validate?

This dual perspective is what transforms an Assurance Engagement into a tailor-made solution, aligned with real-world analysis and decision-making criteria.

The technical foundation behind the report: ISAE 3000

Our Assurance Engagements are structured under ISAE 3000 (Revised), the professional framework applied when:

• A full financial statement audit is not appropriate
• A traditional certification is insufficient
• A customized, technical, and defensible report is required

ISAE 3000 allows the CPA to issue a professional conclusion, with reasonable or limited assurance, on a clearly defined subject matter, using procedures designed exclusively for that specific engagement.

For banks and third parties, this translates into clarity, confidence, and reduced risk of interpretation.

When is an Assurance Engagement recommended?

This type of engagement is particularly valuable when:

• The bank requires more robust support than an income certification
• There is a need to substantiate the source and use of funds
• Structures, transactions, or cash flows require technical explanation
• The objective is to avoid reprocessing and additional information requests
• Risk analysis demands a well-defined and defensible report

In these scenarios, a well-designed Assurance Engagement makes a decisive difference.

What do banks and third parties really review?

Those analyzing these reports are not looking for page volume. They focus primarily on:

• A clearly defined subject matter
• A level of assurance consistent with the objective
• The appropriateness of the applied standard (ISAE 3000)
• Genuine professional independence
• Clear delineation of what was reviewed and what was not

A report that anticipates these elements moves more efficiently through the decision process.

Our approach: making the report work

At JGutierrez Auditores Consultores S.A., we do not offer generic reports. We deliver technical solutions designed to pass real-world scrutiny.

Our process begins with a technical assessment of both the client’s situation and the third party’s requirements, defines the appropriate engagement under ISAE 3000, and delivers a report characterized by:

• Clear and direct language
• Well-defined scope and responsibilities
• A practical focus on the end user

We also provide reasonable professional follow-up, including subsequent clarifications when requested by the report’s recipient.

A report that supports decisions

An ISAE 3000 Assurance Engagement is not an additional formality. It is a strategic tool that reduces friction, accelerates decision-making, and builds trust.

If your case requires more than a standard certification, JGutierrez Auditores Consultores S.A. will help you structure the right engagement, with technical judgment, independence, and a practical approach.
