Internal controls documentation
Internal controls documentation from Finbryn writes down how your financial close, payables, receivables and payroll processes actually run: who approves what, how often, and where duties are split. Our accounting team builds the control matrix and flags gaps in plain language; any formal opinion on those controls comes from an independent audit firm registered in your member state.

Why a written control matters
An auditor, lender or investor rarely asks whether you have controls in the abstract. They ask you to show how one specific control works: who approved this transfer, who reconciled that account, who could enter and approve the same journal entry alone. If the answer lives only in one person's head, that is a gap worth finding first.
We walk your finance team through the close, payables, receivables and payroll cycles, then write process narratives that describe what actually happens today. A control matrix follows, listing each control, its owner and how often it runs.
Segregation of duties in a lean team
Smaller EU businesses often run with one person able to create a supplier, approve the payment and reconcile the account it hit. We flag that concentration honestly and suggest a workable fix, such as a second approver above a set threshold, rather than a checklist line nobody acts on.
What this is and is not
Documenting controls is not an attestation, certification or opinion on whether those controls operate effectively over time. Where a formal opinion is needed, such as under a statutory audit or a service-organisation examination, that determination comes from an independent audit firm registered and authorised to practise in your member state.
This feeds directly into SOC readiness bookkeeping for EU companies preparing for a customer-driven examination, and into working papers when an auditor wants to see how a specific control is evidenced.
A file your next reviewer can actually use
A controls document that sits untouched for two years is worse than no document, since a reviewer will trust it less than a verbal answer. We keep a revision date on the file and flag when a section is overdue for a refresh, so it stays a fair description of how the business runs rather than a snapshot from an earlier stage of growth.
Questions
Frequently asked questions: Internal controls documentation
Is this required for a small EU business?
No regulation requires it at small scale, but a lender, investor or first-time auditor often expects to see it, and it is easier to write down before a problem forces the question.
Will you flag a control gap even when it is uncomfortable?
Yes. A gap we do not flag is a gap your auditor or investor will find instead, so we write it down plainly along with a workable fix.
Do you implement new approval workflows in our systems?
We document the process and matrix and help design a practical fix. Implementing a new workflow inside your systems is done together with whoever owns that software.
Does this help with a French expert-comptable or German Steuerberater review?
It can. A clear control narrative gives your local accountant fewer open questions when they review the file behind your statutory accounts.
How often should this documentation be refreshed?
We recommend a review whenever a process or system changes materially, and a full refresh at least once a year, so the documentation reflects how approvals and access actually work today rather than how they worked a year ago.
Is this a certification of our controls?
No. We document how controls actually work today and flag gaps; any formal attestation or opinion comes from an independent, credentialed auditor you engage separately.
Do we need this if we are a small company?
Even a lean team benefits from writing down who approves what. It shortens the questions an auditor or lender asks and reduces the risk of a single person controlling a whole process.
How do we get started with internal controls documentation?
Getting started with internal controls documentation begins with a short review of your current records and software access. Once that is done we confirm scope and timing in writing, and ongoing work begins on the schedule agreed with you.
What if our records for internal controls documentation are not up to date?
If your records are behind, we scope a catch-up first so internal controls documentation starts from a clean, reconciled base. That catch-up is priced and timed separately from the ongoing engagement, so you always know what each part costs.
