Compilation Engagement: What Your Accountant Actually Signs

Quick answer. A compilation engagement on annual accounts leads the chartered accountant to express limited assurance on the consistency and plausibility of the accounts, governed by professional standard NP 2300 (order of 1 September 2016). The accountant attests, but does not certify: this is neither an audit nor a guarantee that errors or fraud are absent.

When your bank asks for "accounts prepared by the chartered accountant" before granting a loan, it has a specific document in mind: the compilation report. Many directors confuse it with a certification, that is, with an audit. That confusion can be costly, because it implies a guarantee that does not exist, and it hides the real value of the engagement.

At Hayot Expertise, a firm led by a chartered accountant registered with the Ordre des experts-comptables of Île-de-France and a statutory auditor registered with the CNCC, we sign these reports every year. Here is precisely what they commit to, and above all what they do not.

The compilation engagement is the most common accounting mission for small and mid-sized French businesses. The accountant takes part in preparing your annual accounts, drawing on the information you provide, then issues a report on those accounts.

This engagement is defined by a professional standard, NP 2300 "Compilation engagement", developed by the French national council of chartered accountants (Conseil supérieur de l'ordre des experts-comptables) and approved by order of 1 September 2016. It is not a mere firm custom: it is an enforceable normative framework.

The final deliverable is the compilation report. It is a distinct output from the tax return package alone. To see where bookkeeping ends and the report begins, read our comparison of the difference between a compilation engagement and bookkeeping.

This is the key point, and the most misunderstood. A compilation engagement results in limited assurance, sometimes called "negative assurance".

In practice, the accountant attests that nothing has come to their attention that calls into question the consistency and plausibility of the annual accounts taken as a whole, prepared under the responsibility of management in accordance with the applicable accounting framework. It is a deliberately cautious, negative wording.

By contrast, certification of accounts by a statutory auditor rests on reasonable assurance, known as "positive": the professional states that the accounts are true, fair and present a faithful image. The level of work, and therefore the cost, is on a different scale entirely.

Three assurance levels not to confuse#

The wording is not incidental. Article 2 of ordinance no. 45-2138 of 19 September 1945 empowers the chartered accountant to "attest to the regularity and fairness of balance sheets and income statements". The verb "certify" is reserved for the statutory auditor. We detail that perimeter in our article on what the accountant's report covers.

The procedures set out in NP 2300 are real but focused on overall consistency, not on an exhaustive search for anomalies. They follow a few steps.

1. Gathering the information provided by management (documents, statements, contracts, inventories).
2. Applying the firm's accounting technique to take part in preparing the accounts and to check the formal regularity of the bookkeeping.
3. Drawing on the professional's experience and knowledge of the entity and its environment.
4. Analytical procedures: review of the consistency and plausibility of the accounts taken as a whole (trends in margins, balance-sheet items, key ratios).
5. Drafting and signing the compilation report.

The accountant does not perform detailed transaction testing, does not confirm balances with third parties, and does not probe internal control as a statutory auditor would. The compilation may cover annual or interim accounts, but it does not apply to consolidated accounts.

This is where the most frequent misunderstandings arise, with directors and with third parties.

• It is not an audit: no systematic search for material misstatements.
• It is not a certification: the accountant attests, but does not guarantee a faithful image.
• It is not a fraud-free guarantee: limited assurance covers only overall consistency and plausibility.
• It is not a review of management: the merits of management decisions stay out of scope.
• It does not apply to consolidated accounts: a consolidated group falls under other engagements.

The underestimated risk. A director who believes they have "audited accounts" because their firm signed a compilation report may make decisions, or reassure a buyer, on a basis they overestimate. Conversely, some bankers demand certification where a simple compilation would suffice. Clarifying the right assurance level avoids needless cost in both directions.

The compilation report is routinely requested by banks, public authorities and certain partners as a signal of formal reliability. It indicates that an independent professional registered with the Ordre, bound by a code of ethics, took part in preparing the accounts and found nothing inconsistent.

That signal has value, but it must be presented for what it is: limited assurance, not an absolute guarantee of accuracy. A lender also reads the report as evidence that the accounts were not assembled in-house without professional oversight.

When the stakes rise (major fundraising, sale, presence of investors), third parties may demand a higher level: certification by a statutory auditor. We explain that handover in our article on the statutory auditor's certification mission.

Certification is not a matter of comfort: it becomes mandatory above certain thresholds. For financial years beginning on or after 1 January 2024, following the increase made by decree no. 2024-152 of 28 February 2024, appointing a statutory auditor is mandatory when the company exceeds two of the three thresholds below.

Lower thresholds apply to controlled companies required to appoint an auditor: total balance sheet above 2.5 M EUR, net turnover above 5 M EUR, more than 25 employees. Below these thresholds, the compilation engagement remains the usual framework, unless there is a voluntary appointment or a clause in the articles.

• Company below the auditor threshold: the compilation engagement is the standard framework. It is what the bank will ask for.
• Company above the thresholds: certification by a statutory auditor becomes mandatory. Attesting and certifying are distinct functions, largely incompatible on the same entity.
• Interim accounts: a compilation may cover a mid-year closing, useful for a financing file in the middle of the year.
• Group with consolidation: NP 2300 does not apply to consolidated accounts, which fall under other engagements.

Recently, a director of a small business approached us after a credit application was refused. Their former provider had delivered a tax return package, with no signed compilation report. The bank, which expected that specific deliverable, treated the accounts as unsupported by a professional. The misunderstanding was less about the quality of the figures than about the absence of the expected document.

Our reading. The value of a compilation engagement does not lie only in the final report: it lies in the upstream review of the accounts' consistency, which secures your tax filings and your banking negotiations. It is a reliability signal, provided its scope is respected.

What the authorities look at. The profession's code of ethics (decree no. 2012-432 of 30 March 2012) requires a written engagement letter setting out the scope of work and the fee terms. Without it, the perimeter of the report is unclear, and each party's responsibility poorly framed. It is the first document to require.

Hayot Expertise advice. Before signing an engagement letter, check that it explicitly states the "compilation of accounts" nature and the limited assurance level. Ask your contact which deliverable the bank needs: a compilation report or a certification. If you are approaching the auditor thresholds, plan the transition rather than facing it under pressure.

• Do not confuse a compilation report with certification: only the auditor thresholds trigger a statutory audit obligation.
• Require a written engagement letter (decree 2012-432) before any work begins.
• Check that the report is signed by a chartered accountant registered on the Ordre's roll, the only person entitled to attest a third party's accounts.
• Anticipate e-invoicing compliance: receiving electronic invoices becomes mandatory for all VAT-liable businesses on 1 September 2026, which strengthens the accounting data presented.
