Cycle-based accounts review: the working paper method

Quick answer. An accounts review is the set of controls a firm performs on the accounts before the annual financial statements are drawn up, to justify every balance and confirm the true and fair view. Rather than account by account, the firm reviews by homogeneous cycles (cash, purchases, sales, fixed assets, payroll) using lead schedules and a structured working paper file.

Many business owners think accounting ends with entering invoices and reconciling the bank. That is the most visible step, but not the one that truly secures your accounts. The decisive moment is the review: the methodical control of every balance before the balance sheet is locked, the tax return produced and the engagement deliverable signed. Clean but unreviewed bookkeeping can easily hide a missing expense, a double-counted revenue item or a mis-valued inventory.

This article explains how a firm structures that work. Why we review by cycles rather than account by account, what we control within each cycle, what a lead schedule is for, what the permanent file and the annual file contain, and how this review differs from the statutory audit performed by a French statutory auditor.

An accounts review is the body of controls performed on a financial year's accounts to confirm they are lawful, faithful and give a true and fair view of the entity's assets, financial position and result. This is a substantive requirement set by the French Commercial Code (art. L.123-12 onward): keeping books is not enough; the annual accounts must faithfully reflect reality.

In firm practice, the review most often forms part of a compilation engagement (mission de présentation des comptes), governed by the professional standards of the French Institute of Chartered Accountants (Ordre des experts-comptables). At the end of that engagement, the chartered accountant issues an attestation expressing moderate assurance on the consistency and plausibility of the accounts. It is not an audit opinion, a point we return to below.

In practice, reviewing means answering one simple question for every line of the balance sheet and income statement: is this balance justified, and by what? Justification rests on supporting evidence: bank statements, subledgers, contracts, invoices, depreciation schedules, social and tax filings. The accounting entries file (FEC) and reconciliations feed this work from start to finish.

The concrete objectives of a review#

• Justify each balance of the balance sheet and income statement with supporting evidence or a documented calculation.
• Detect anomalies: duplicates, omissions, misallocation, period cut-off errors.
• Check that expenses and revenues are attached to the correct financial year (cut-off).
• Prepare the tax return and secure the transition from accounting result to taxable result.
• Build a structured memory of the file, reusable the following year.

A chart of accounts contains hundreds of accounts. Going through them one by one, in ledger order, would be both endless and unreliable: you would control isolated balances without seeing the links between them. Entries work as flows. A purchase invoice, for example, hits an expense account, a deductible VAT account and a supplier account at the same time. Isolating them makes no sense: they are controlled together.

Review by cycles therefore groups accounts into homogeneous sets, linked by the same economic logic and the same flow. A complete cycle is reviewed in one go, which lets you cross-check information and reason by overall consistency rather than by unit balance.

Our take. Reviewing by cycles means shifting from arithmetic verification to investigation. You do not just ask whether an account is correct, but whether the story this cycle tells is consistent. A sales cycle where receivables rise sharply while cash stagnates raises an immediate question that no account-by-account control would surface.

This approach offers three operational advantages. It avoids blind spots, because a cycle forces you to sweep every account tied to the same flow. It lets work be split between team members by cycle. And it makes the review traceable: each cycle maps to a summary schedule, and the file's progress can be read at a glance.

There is no single regulatory split of cycles: each firm adapts its own naming. Here is the breakdown we use and the key controls attached to it.

For each cycle, the work consists of testing five assertions you will find in any firm: existence (the balance reflects reality), completeness (nothing is missing), valuation (the amount is correct), period separation and attachment to the right financial year. This framework drives the depth of controls: a bank account is justified by a reconciliation, inventory by a valued count, provisions for liabilities and charges by a documented estimate.

The underestimated risk. Cut-off, meaning period separation, is the most frequent and most costly anomaly. A service invoice received in January but relating to December must be attached to the closed financial year. Forgetting it understates the expense and artificially inflates the result, hence the tax. French tax guidance (BOFiP) is clear on the financial year to which expenses attach: the review is precisely when these mismatches are caught before they distort the tax return.

The lead schedule (feuille maîtresse) is a cycle's summary document. For each cycle, it recaps the balances of year N and year N-1, shows the variations, and refers to the controls performed and the supporting evidence attached.

It is what materialises the cycle's justification. A reviewer opening a lead schedule should be able to read, on one page: where the balance stands, how it has moved since last year, which controls were performed, and where to find proof of each material amount. Until a line is justified, the cycle is not reviewed.

A typical cycle, step by step#

1. Open the lead schedule and carry forward the N and N-1 balances of every account in the cycle.
2. Analyse material variations and identify what needs explaining.
3. Match each balance to its supporting evidence (statement, subledger, contract, schedule).
4. Test period cut-off: goods received not invoiced, invoices to be issued, deferred and prepaid items.
5. Document the controls performed, anomalies found and proposed adjusting entries.
6. Conclude the cycle: sign off the lead schedule and flag points to validate with the owner.

In practice. A lead schedule only has value if a third party can read it. In our files, the rule is simple: a colleague, or a future statutory auditor, must be able to reconstruct our reasoning without calling us. An uncommented variation, a balance not tied to evidence, and the cycle is treated as open.

The working paper file gathers every element that proves and organises the review. It splits into two complementary sets.

The permanent file avoids requesting the same documents every year and gives the reviewer the legal and economic context of the entity. The annual file is the living record of the year: it serves as proof of the work done and as memory for the next closing. Kept well, it saves considerable time year on year and smooths external controls, whether a tax inspection or a statutory auditor's engagement.

Technically, this work now relies on dedicated review tools. A review tool such as MyUnisoft structures cycles, attaches evidence to balances and automatically computes N / N-1 variations, which secures traceability and speeds up file completion.

A firm's accounts review and a statutory auditor's statutory audit share common techniques (cycles, working papers, assertion-based controls), but answer different frameworks and purposes. The distinction matters because it determines the level of assurance you obtain.

The chartered accountant who prepares and reviews the accounts cannot, for the same entity, also be the statutory auditor who certifies them: this is an independence rule. In practice, a compilation engagement leads to moderate assurance, a statutory audit to higher assurance expressed as an opinion. A well-kept working paper file greatly facilitates the auditor's work, as they will rely on your lead schedules to direct their own controls. For entities subject to audit, such as certain building project managers exceeding the thresholds, the link between the two engagements must be anticipated from closing.

For context, the French general chart of accounts derives from ANC regulation no. 2022-06, applicable to financial years opened on or after 1 January 2025. This is the framework setting the measurement and presentation rules that the review verifies.

Recently, while reviewing the fixed-assets cycle of a construction client, we noticed that significant equipment had been booked as an expense rather than capitalised. The entry went unnoticed in the ledger: one amount among others in a purchase account. It was the cycle's lead schedule, by revealing an abnormal variation in the repairs and maintenance line relative to activity, that triggered the analysis. The correction changed the year's result, the depreciation schedule for the following years and the tax base. Without review by cycles, the error would have passed through closing.

This case illustrates our conviction: a review's value lies not in the quantity of controls but in their relevance. A few targeted controls on the risky cycles (inventory, fixed assets, purchase and sales cut-off) are worth more than a uniform, shallow sweep. In the files we take over, the most frequent sticking points are rarely fraud: they are suspense accounts never cleared, shareholder current accounts without justification, and accruals forgotten from one year to the next.

Watch points. Three signals always alert us: a suspense account (471) that survives from one year to the next, a shareholder current account moving without an agreement or evidence, and an accounting cash balance that does not reconcile to the statement. None is necessarily serious, but each deserves a written explanation in the file. It is also what the tax authorities look at first during an inspection.

The review is also the right time to prepare pre-closing tax decisions: once the accounts are justified, the result is reliable, and year-end choices (provisions, depreciation, allocation) rest on secure ground. Understanding this mechanism also helps with reading a balance sheet: each line tells the story of the cycle that produced it.
