Audit preparation and external-auditor coordination

Annual & Periodic Audit Support in the Netherlands

NetherBridge Partners helps Dutch companies, foreign-owned entities and international groups prepare the financial schedules, reconciliations and supporting information requested during annual, interim and group audits.

Depending on the agreed scope, we can coordinate the audit request list, prepare supporting schedules, track auditor questions, help explain financial information and follow approved adjustments through the accounting records.

Quick answer

What Annual and Periodic Audit Support Means

Audit support prepares and organises the company’s side of an external audit. This may involve closing and reconciling the accounting records, preparing requested schedules, collecting supporting documents and coordinating responses to the auditor.

Periodic support can begin before year-end. Monthly or quarterly reconciliations, interim-audit preparation and follow-up of earlier findings can help the company maintain a more structured audit file throughout the year.

NetherBridge does not replace the independent auditor. The auditor determines the audit procedures, evaluates the evidence and issues any audit opinion.

Audit Preparation for Different Business Situations

The appropriate support depends on why the audit is being performed, which auditor is involved and how complete the company’s records are.

01

First Statutory Audit

Preparation of opening balances, comparative information, historical schedules and supporting records for a company entering an audit requirement.

02

Recurring Annual Audit

Year-end audit-file preparation, reconciliations, supporting schedules and coordination of the external auditor’s requests.

03

Interim Audit

Preparation for work performed before year-end, including process information, control evidence and selected transaction support.

04

Group or Component Audit

Support for a Dutch entity responding to instructions and reporting deadlines from a parent company or group auditor.

05

Voluntary Audit

Preparation for an audit requested by shareholders, investors, lenders, a parent company or another stakeholder.

06

Temporary Finance Capacity

Practical support where the internal finance team needs additional capacity during closing, file preparation or auditor follow-up.

Dutch audit requirement

Does Your Company Need a Statutory Audit?

Current Dutch guidance classifies companies using balance-sheet total, net turnover and average employee numbers. A company generally falls into a size category when at least two of the three relevant criteria are met for two successive financial years.

Medium-sized and large companies generally need an audit opinion as part of their annual-reporting package. However, the assessment can depend on consolidated figures, group relationships, the financial year, sector-specific rules and whether an exemption may apply.

The position should be checked before the audit timetable is planned. A voluntary audit, review or group-audit requirement may also apply even if the Dutch entity is not independently subject to a statutory audit.

Regulated assurance

The Independent Auditor’s Role

A statutory audit must be carried out by an appropriately licensed audit firm. The auditor is responsible for independence, the audit approach, materiality, evidence requirements, conclusions and the audit opinion.

NetherBridge can help the company prepare information and manage the operational process. We do not issue the audit opinion and cannot determine which evidence the auditor will accept.

Important: audit support does not guarantee completion by a particular date, acceptance of the audit file or an unmodified audit opinion.
Service scope

What Audit Support May Include

Support can cover one part of the audit process or a coordinated preparation project. The exact responsibilities are agreed after reviewing the auditor’s requests, the accounting records and the internal finance capacity.

01

Planning and Timetable

Align key dates, reporting responsibilities, internal owners and dependencies with the company’s closing and audit calendar.

02

PBC Request Management

Review the “prepared by client” request list, assign owners, track deadlines and maintain an overview of submitted and outstanding information.

03

Reconciliations and Schedules

Prepare or review account reconciliations, movement schedules, calculations and explanations based on the available accounting records.

04

Financial Statements and Consolidation

Support the preparation of draft financial statements, consolidation schedules or group-reporting information where included in scope.

05

Auditor Questions and Adjustments

Coordinate questions, collect further evidence and track proposed adjustments for management review and approval.

06

Post-Audit Follow-Up

Process approved entries, update schedules, track findings and improve recurring close or audit-preparation instructions.

Audit-ready records

What an Audit File May Contain

The precise information depends on the auditor’s approach, materiality and request list. The examples below show common financial areas that may require schedules and supporting documents.

Financial area Possible schedule Possible supporting information
Cash and banks Bank reconciliation and list of outstanding items. Bank statements, confirmations, payment details and explanations of reconciling items.
Trade receivables Aged debtor list and general-ledger reconciliation. Customer invoices, receipts, credit notes, collection information and balance explanations.
Trade payables Aged creditor list and general-ledger reconciliation. Supplier invoices, payment records, unmatched items and subsequent-payment information.
Revenue Revenue reconciliation and breakdown by relevant category. Contracts, invoices, delivery information, credit notes and cut-off support.
Fixed assets Opening-to-closing asset movement schedule. Purchase invoices, disposals, depreciation calculations and asset-register details.
Payroll Payroll-to-ledger and payroll-tax reconciliation. Payroll reports, employment information, tax filings and payment records.
VAT and tax accounts Return-to-ledger and assessment reconciliation. Returns, assessments, correspondence, payments and explanations of differences.
Equity and financing Equity movement and loan schedules. Shareholder resolutions, loan agreements, interest calculations and bank documentation.
Intercompany Balance and transaction reconciliation by counterparty. Group confirmations, invoices, agreements, settlement details and foreign-exchange calculations.
Estimates and provisions Movement and calculation schedule. Management assumptions, underlying data, contracts and approval documentation.
The auditor decides: these examples do not determine the audit scope. The independent auditor decides which accounts, transactions, controls and supporting evidence need to be examined.
Different audit cycles

Annual, Interim, Periodic and Group Audit Support

Support type Main purpose Typical timing Typical focus
Annual audit support Prepare the company’s records and schedules for the year-end external audit. Shortly before and after the financial year-end. Annual accounts, closing balances, reconciliations and supporting evidence.
Interim audit support Prepare information for audit work carried out before year-end. During the financial year. Processes, controls, selected transactions and early issue identification.
Periodic audit readiness Maintain more structured records throughout the year. Monthly or quarterly. Balance-sheet reconciliations, control evidence and open-point tracking.
Group or component audit Support a Dutch entity responding to parent-company or group-auditor instructions. Based on the group reporting calendar. Reporting packages, mappings, intercompany balances and group-request coordination.
First-year audits

Preparing for a First Statutory Audit

A first audit may require information that was not previously maintained in an audit-ready format. Opening balances, comparative figures and older transactions may need additional support.

Opening balance documentation
Comparative-period information
Historical fixed-asset records
Earlier contracts and financing
Prior accounting policies
Entity and group changes
Missing historical evidence may not always be reconstructable. The available records and possible alternatives should be discussed with the auditor early.
International groups

Supporting Dutch Entities in Group Audits

A Dutch subsidiary may have to respond to local audit requests and separate instructions from a foreign parent company or group auditor. These workstreams may use different formats, deadlines and account mappings.

Group-auditor instructions
Component reporting packages
Local-to-group account mapping
Intercompany confirmations
Consolidation schedules
Foreign finance-team coordination
Clear responsibilities

Our process

From Readiness Review to Post-Audit Follow-Up

The stages can be adapted to an annual audit, interim review period, first-year audit or group-reporting cycle.

STEP 01

Define the scope

Review the audit timetable, reporting framework, auditor requests, internal resources and group instructions.

STEP 02

Assess readiness

Identify unreconciled balances, missing documents, unclear responsibilities and priority accounting issues.

STEP 03

Close and reconcile

Complete agreed closing tasks and prepare the required account reconciliations and movement schedules.

STEP 04

Build the audit file

Organise schedules, calculations, contracts and supporting documents in a structured submission file.

STEP 05

Coordinate questions

Track follow-up requests, assign owners and support explanations or further evidence where available.

STEP 06

Finalise and improve

Process approved adjustments, close open points and update the preparation approach for the next cycle.

Preparing the engagement

Information We Usually Need

The initial review is more effective when the audit instructions, prior findings and underlying financial records are available together.

If the external auditor has already issued a request list, share the latest version together with its deadlines and submission instructions.

Scope, timing and fees

What Affects the Engagement?

The required work usually depends on whether this is a first or recurring audit, the number of entities, consolidation requirements, the volume of auditor requests and the quality of the accounting records.

Unreconciled accounts, missing evidence, historical issues, complex estimates, group instructions and short auditor deadlines can increase the preparation work.

Timing also depends on the availability of management, internal process owners, the external auditor and relevant third parties. A working plan can be confirmed after an initial review.

Common preparation risks

Issues to Address Early

Unreconciled balance-sheet accounts
Incomplete supporting documents
Unclear ownership of requests
Different versions of schedules
Unresolved prior-year findings
Late management judgments
Unconfirmed intercompany balances
Insufficient time for review

Frequently asked questions

Annual and Periodic Audit Support in the Netherlands

What is annual audit support?

Annual audit support prepares and coordinates the company’s side of the year-end audit. Depending on scope, this may include closing support, reconciliations, audit schedules, document collection, request tracking and coordination of auditor questions.

What is periodic or interim audit support?

Periodic support helps maintain audit-ready records during the year. It may include monthly or quarterly reconciliations, interim-audit preparation, control documentation and follow-up of open audit points before the final year-end audit.

What is the difference between audit support and an external audit?

Audit support prepares records and coordinates information on behalf of the company. The external auditor is independent, determines the audit procedures, evaluates the evidence and issues any audit opinion.

Does our Dutch company require a statutory audit?

Medium-sized and large Dutch companies generally require an audit opinion, based on the applicable company-size assessment. Group figures, consecutive financial years, sector rules and possible exemptions may affect the position, so the requirement should be checked for the particular entity.

What is a PBC list?

PBC means “prepared by client.” It is the auditor’s list of schedules, documents, explanations and other information the company is asked to provide. Audit support can help assign owners, prepare requested information and track submissions and follow-up questions.

Can you help with our first audit?

Yes, subject to reviewing the records and agreed scope. First-year support may include opening balances, comparative information, historical schedules and earlier supporting documents. Missing historical evidence may not always be reconstructable.

Can you communicate directly with our external auditor?

Auditor communication and request coordination may be included with management’s approval. Management remains responsible for the financial statements, accounting judgments, representations and final approval of information supplied.

Can audit support guarantee an unmodified audit opinion?

No. The independent auditor determines the procedures, evaluates the evidence and reaches the audit conclusion. Audit support cannot guarantee acceptance of information, completion by a particular date or any specific audit opinion.

Is specialist IT-audit work included?

Ordinary system reports, user lists and data exports may form part of the financial audit file. Formal IT assurance, cybersecurity testing, penetration testing or specialist evaluation of automated controls is separate work and may require an appropriate IT-audit specialist.

What determines the timing and price?

Timing and fees depend on the number of entities, first-year or recurring status, consolidation, request volume, source-data quality, open reconciliations, historical findings, group instructions and the availability of management, auditors and third parties.
