Taking over a business: preparing the accounting and tax review

Prepare for a business takeover in Luxembourg: accounts, cash flow, commitments, employees and questions to resolve before negotiating and signing.

A business that is already operating may seem easier to take over than to create. It has customers, tools and a history. That history also contains commitments that the stated price does not reveal. Before imagining yourself in your new role, build a file that explains what you are buying, what the business can actually finance and what remains to be clarified.

Defining what you intend to buy

Write a precise description: shares in which company, what proportion, what voting rights, or which assets and activities? Specify the premises, brands, software, files and contracts essential to the business. This work avoids negotiating a price for a long time when you and the seller are not discussing the same scope. A common trade name is not enough to identify the owner of each item.

An acquisition audit must follow this scope. Organise a document room with restricted access, dated versions and a list of questions. Request sensitive information gradually and according to each party’s rights; an interest in a takeover does not authorise the uncontrolled circulation of customer or employee data. Keep a record of the documents actually reviewed and of answers still missing.

Checking the quality of the accounts and profit

Gather several financial years and a recent financial position, then reconcile the accounts with the information explaining them. Review sales by business activity, customer concentration, overdue receivables, inventory and deferred expenses. A strong most recent financial year may depend on a single order or postponed investment. The guide to reading the profit and loss account helps distinguish sales growth from margin improvement.

Build a documented bridge between accounting profit and the profit used for your forecast. Specify the costs that will continue after the manager’s departure and those related to their replacement. Do not automatically remove every expense presented as exceptional. If an event recurs, or if your own organisation requires an equivalent expense, the adjustment may conceal an ongoing need. Have significant estimates and proposed adjustments explained.

Reviewing commitments beyond the balance sheet

Request financing agreements, guarantees, leases, commitments with related parties and litigation files. Maturities, change-of-control clauses and termination options may affect the feasibility of the takeover. Also verify the rights to the tools and creations used: paying for the shares does not remedy a missing licence or a contract signed by the wrong entity.

The tax and social security review covers returns, payments, correspondence with authorities and ongoing audits. A certificate or filed return alone does not prove that all past treatments are correct. For teams, have the transfer rules and applicable obligations assessed before developing a scenario to reduce or amend contracts. The ITM recalls the preservation of rights in the context of a relevant transfer of undertaking.

Financing the first months after the takeover

Distinguish the purchase price, transaction costs, necessary investments and money required by operations. The working capital requirement may increase with the season or payment terms. A profitable business may lack cash if its invoices are collected after wages and suppliers are paid. Prepare a central scenario and a less favourable scenario.

The thirteen-week cash flow plan makes it possible to schedule these needs. Identify who pays each expense: the acquirer, the target company or another entity. This distinction matters as much as the total. Do not automatically use the target’s cash to finance the purchase of its own shares; the legal possibility and financial conditions must be reviewed separately.

Turning findings into negotiable decisions

Classify the points according to their consequence: price to be revised, document to obtain, condition precedent, seller’s undertaking or transition arrangements. A contractual warranty merits a review of its scope, exclusions, duration and implementation. Its practical value also depends on the ability of the person giving it to honour their commitment.

Before signing, have a summary reviewed that distinguishes confirmed facts, assumptions and unresolved points. Then prepare the handover: contacts, access, filing calendar, bank, suppliers and monitoring of commitments. For a transaction involving SARL shares, continue with the share transfer file. The decision must remain understandable even to someone who did not attend all the meetings.

The table for taking action

Financing does not stop at the stated price

Fictional example: the negotiated price is 200,000 euros. The acquirer also plans for 15,000 euros in costs, 25,000 euros to upgrade tools and 40,000 euros in initial cash requirements. Their plan must therefore explain 280,000 euros in resources and their allocation among the persons concerned. This illustrative calculation is neither a valuation nor a recommended financing structure. It shows why having only the purchase price is not enough to get started under good conditions.

Your preparation checklist

  • Define the shares or assets and the exact scope.
  • Organise document access and confidentiality.
  • Compare several financial years and a recent financial position.
  • Explain profit adjustments.
  • List contracts, disputes and guarantees.
  • Review employees and authorisations.
  • Finance costs, investments and the operating cycle.
  • Assign each unresolved point before signing.

Frequently asked questions

Are profitable accounts enough to make a decision?

No. You must also understand the quality of profit, commitments, cash flow and the resources needed after the takeover.

Does buying assets remove all obligations?

No. The contractual scope and applicable rules, particularly those concerning the transfer of employees, require separate analysis.

Does a seller’s warranty replace reviewing the file?

No. It must be negotiated and understood; it does not eliminate missing information or all risks.
