Accounting and Accountancy Expertise
Rigorous accounting is the foundation of any healthy business. We support you in fully managing your accounts, in strict compliance with Luxembourg standards, so you always have a clear, reliable view of your financial position.
A thorough understanding of your situation lets us support you with one constant aim: simplifying your processes and helping you make the best decisions.
ESSENTIAL INFORMATION FOR STEERING YOUR COMPANY
Too often seen as a mere legal obligation, accounting is, above all, your business's universal language. It means recording, classifying and summarising every financial flow within your structure, turning your operational reality into figures. Far more than a pile of invoices, it produces your financial statements (balance sheet and income statement), giving an accurate snapshot of your accounts at any given moment.
What's it really for? Beyond the compliance obligations, it's the business owner's compass. Rigorous, up-to-date accounting lets you measure your true profitability, anticipate financing needs and stay on top of cash flow.
By turning raw figures into performance indicators, accounting becomes a strategic management tool: it helps you validate your investment decisions, reassure business partners, and make informed choices to secure the long-term success of your venture in Luxembourg.
Support tailored to your profile, whether you are...
Tailor-made accounting support
As a self-employed professional, freelancer or craftsperson, time is your most valuable resource. Yet accounting obligations are a heavy, often time-consuming and demotivating burden — the kind that always seems to get pushed to tomorrow.
Because every journey is different, your dedicated advisor takes the time to understand your challenges. We offer a tailor-made approach — combining close support, digital tools and strategic advice — to give you a clear, reliable view of your cash flow and optimise wherever possible.
Designed to adapt to your needs, our range of solutions includes:
Full or shared bookkeeping
Preparation and filing of annual accounts: rigorous preparation of your balance sheet and profit-and-loss account in line with Luxembourg accounting standards.
Cash flow and budget management, taking into account upcoming adjustments and ongoing projects.
- Accounting reporting: dashboards to track your profitability and manage cash flow in real time.
- Tax filings and forward planning: strategic advice on how you pay yourself, managing business expenses, and the social protection tied to your self-employed status, through our dedicated Tax service (corporate tax, personal income tax and VAT).
Focus on your core business
Doctors, lawyers, architects, consultants: your expertise is the heart of your value. Yet practising a liberal profession in Luxembourg demands an administrative rigour that can eat up your time.
Because your needs differ from those of a shopkeeper or craftsperson, we offer specific support built around two goals: freeing you from accounting and administrative obligations, and giving you a clear view so you can confidently balance your professional income with the growth of your personal wealth.
Designed to meet the requirements of liberal professions, our range of solutions includes:
Tailored bookkeeping: precise tracking of income and expenses, with smooth integration of your professional tools for simplified data entry.
Preparation of annual accounts and filings: rigorous preparation of your balance sheet and profit-and-loss account, ensuring full compliance with Luxembourg standards.
Cash flow management and expense forecasting: anticipating your social security contributions (CCSS) and tax instalments to avoid cash flow surprises at year-end.
Dashboards and reporting: real-time tracking of your key indicators (fees, office expenses, margins) via our digital tools.
Tax and social optimisation for business owners: strategic advice on how you pay yourself, managing business expenses, and the social protection tied to your self-employed status, through our dedicated Tax and VAT service.
Solid foundations for your growth
Whether it's a family-run SME, a local shop or a "Made in Luxembourg" service company, running a business calls for a 360° view.
Because we share your local roots, we offer a tailor-made approach that goes beyond straightforward accounting: we turn your financial data into decision-making tools that secure your business's future and protect your investments in the Grand Duchy.

What is the difference between an accountant and a certified accountant of the OEC ?
The distinction between a bookkeeper and a chartered accountant is strictly regulated by law: practising as a chartered accountant requires registration with the Institute of Chartered Accountants, which sets specific rules its members must follow. Although both can handle your day-to-day bookkeeping, their responsibilities differ — the chartered accountant brings deeper expertise in strategic and tax advisory work, can carry out audits and reviews, offer domiciliation services, and handle the accounts of companies with a balance sheet total above €2.3 million or turnover above €4.6 million.

What are the accounting requirements for a limited liability company (SARL) in Luxembourg ?
Every commercial company must keep proper accounts, prepare annual accounts (balance sheet, profit-and-loss account, notes) and have them approved by the General Meeting within 6 months of the year-end closing. As chartered accountants, we're here to help prepare these documents, draft the minutes of the General Meeting, and file them with the Trade and Companies Register (RCS) as the law requires.
What are the four types of accounting ?
There are generally four main categories, each meeting different needs — from legal obligation through to strategic business management:
- General (or financial) accounting: the mandatory basis for every company, strictly governed by the Standard Chart of Accounts (PCU). Its purpose is to record all financial flows chronologically (purchases, sales, salaries) to produce official documents such as the balance sheet and income statement.
- Analytical (or management) accounting: unlike general accounting, this isn't mandatory, but it's the business owner's "dashboard" — used to calculate precise cost prices and margins by product, project or department.
- Budgetary accounting: the forecasting tool par excellence, used to project income and expenses for the coming year and compare actual figures with forecasts month by month (variance analysis).
- National accounting: managed not at company level but at State level (STATEC), summarising data from all companies and households to measure the country's economic health.
When and why should you choose outsourcing ?
Your choice should depend on your structure's operational maturity: full outsourcing offers peace of mind for a company just launching, or for a micro-business, since it hands responsibility for compliance (VAT, financial statements, eCDF) to a fiduciary for a predictable flat fee. Team reinforcement, by contrast, is a strategic option if you already have an in-house accounting base but are facing a spike in activity or a one-off technical challenge (year-end closing, audit, digital transition).
Software processes data; an accountant also processes its context. Far from being limited to remote execution, our experts are genuine advisors you can turn to at the slightest doubt. In Luxembourg, close working relationships and in-depth knowledge of administrative contacts can unlock situations no algorithm could handle — and with our digital tool My OmniTrust, you don't have to trade away process flexibility to get it.
Why choose a local accountant over a 100% software-based solution ?
Software processes data, but an accountant also takes the context into account. Far from merely performing tasks remotely, our experts are true advisors whom you can turn to whenever you have any questions. In Luxembourg, close relationships and in-depth knowledge of administrative officials allow us to resolve situations that an algorithm cannot handle. What’s more, you don’t have to compromise on process flexibility thanks to our digital tool My OmniTrust.
