— An accounting firm, but not like the others
Real-time accounting, not left to year-end.
Most accounting firms work in a silo: you send in your folders, you get financial statements back months later. Advena does the opposite. We keep your accounting on Odoo, as you go, and we draw decisions from it, not just compliance.
-
Accounting in near real time, on Odoo
We always keep your accounting on Odoo. We've invested in our processes to post entries in near real time: your entries, invoices and reconciliations are kept up to date continuously. You see your accounts at all times, not three to six months after the year-end close as too often happens elsewhere. Not using Odoo yet? We set you up on it, and you walk away with a complete ERP.
-
A single point of contact for everything
Accounting, financial steering, management tools: a single team that knows your business, often since it was founded. No more back-and-forth between your accounting firm, your bank and your IT provider. Everything is consistent from day one, with no need to relearn your context.
-
Books that steer, not books that sleep
Beyond bookkeeping and legal obligations, we turn your figures into decisions. Every month you receive a report on your financial position (cash flow, cost trends, revenue, VAT balance), and your dedicated contact reviews it with you in 15 to 30 minutes. A real look at your business, included in the fee.
-
Rooted in Luxembourg
We know the Luxembourg tax and social framework, RCS filings and RESA publication, VAT and CCSS deadlines, and sector-specific rules. Accounting that is compliant and put in context, not a generic treatment transposed from another market.

— Our pricing commitment
An all-inclusive fee from 325 €/month. No extra charges.
Many accounting firms bill by the hour or pile on extras: one more filing, a question by email, a slightly longer year-end close, and the bill climbs. At Advena, it's a single monthly fee that covers everything, agreed up front. You know exactly what you pay, all year, with no nasty surprises.
No fees during the year
A call, a reminder, a question by email, an additional filing: none of that is billed extra. The amount doesn't change from one month to the next. You budget your accounting once and for all.
Monthly report and call included
Every month, a report on your financial position (cash flow, cost trends, revenue, VAT balance) and a 15-to-30-minute call with your dedicated contact to understand your figures, guide you and answer your questions. Included in the fee, not an add-on.

— How the handover works
From your current accounting firm to Advena, seamlessly.
Switching accounting firms is daunting: the fear of losing history, missing a deadline, having to explain everything again. Our handover method is designed to make the transition invisible to your business.
-
01
We understand your situation
A phone or video call to understand your business, your volumes, your VAT regime, your deadlines and the state of your current accounting. We give you a flat-fee quote. Free, no commitment.
-
02
We collect your file
Once the engagement letter is signed, we organise the handover of your file from your former accounting firm: trial balances, general ledger, journals, latest annual accounts, VAT positions. All you have to do is give your approval — we handle the exchanges between professionals.
-
03
We set everything up on Odoo
Setting up your accounting in Odoo: chart of accounts, opening balances, bank connections, journals and VAT. If you don't use Odoo yet, we set you up on it. Continuity with the previous financial year is ensured, with no break in history.
-
04
We keep your books
Data entry, reconciliations, VAT returns, payroll: your accounting is kept at the agreed pace (monthly or quarterly). You drop off your documents as you go, we process them, and you keep a clear view of your accounts at all times.
-
05
We close and file
At year-end: financial statements, annual accounts, tax returns, RCS filing and RESA publication, on time. We walk you through your accounts with commentary, not just a PDF to file away. You understand what they say about your business.

No forced lock-in. Your accounting lives on Odoo, an open standard: your data can be handed back to you at any time, in a usable format. If one day you leave, your history goes with you, cleanly.
— Frequently asked questions · Accounting firm
The real questions
before switching accounting firms.
6 answers to the questions we're asked most often.
Do you have to redo my whole accounting from scratch?
No. The handover happens mid-year from the latest trial balance and the opening balances provided by your former accounting firm. We take over the history needed to ensure continuity (previous annual accounts, VAT positions, fixed assets), without re-entering everything from the day your company was founded. The transition is organised so it causes no disruption and no missed deadline.
Can I switch accounting firms mid-year?
Yes, it's entirely possible and common. We organise the collection of your file from your current accounting firm and take over from the existing position. We handle the exchanges between professionals; on your side, a simple approval is enough to start the transition. The best time is just after a year-end close, but we can take over at any stage.
Do I have to use Odoo to work with you?
We always keep your accounting on Odoo: that's what lets us post entries in near real time and give you an always-up-to-date view. If you already use Odoo, your figures are kept right there. If you don't use it yet, we set you up on it with our Odoo ERP : you lose nothing — quite the opposite, you walk away with a complete ERP on top of your accounting.
How much does your service cost, and what's included?
An all-inclusive fee from 325 €/month. It covers your bookkeeping, VAT, financial statements and annual accounts, tax returns, RCS filings, payroll, your everyday exchanges and questions, as well as a monthly report on your financial position and a monthly call with your dedicated contact. No extra fees during the year: the amount agreed does not change. It is refined based on your volumes (entries, employees, filings) during the first conversation.
Do you also handle my employees' payroll?
Yes. We prepare payslips, periodic social filings (CCSS, ITM), and we manage staff arrivals and departures. We also provide basic advice on labour law and your employment contracts. Payroll can be included in your fee or added according to your needs.
What exactly does the monthly follow-up include?
Every month you receive a report on your financial position: cash flow, cost trends, revenue, VAT balance and the points to watch. Then your dedicated contact spends 15 to 30 minutes with you to go through your figures: what they say about your business, upcoming deadlines, your questions. It's not just a PDF in your inbox — we explain your figures and guide you in your decisions. It's included in the fee, at no extra cost.
