Your Customer Contracts May Not Survive a Change of Ownership

A buyer asks a simple question late in a sale process: which legal entity is actually entitled to this revenue after completion? The answer should not be a scramble through shared drives, old inboxes and a commercial director's memory. Yet that is how many otherwise well-run manufacturing and engineering businesses discover that the revenue they describe as contracted is not as portable as they assumed.

This is not an argument that customer contracts vanish whenever ownership changes. Many continue. The point is more practical. A customer relationship, a framework agreement, a purchase order and a payment history are different forms of comfort. A buyer will want to know what will continue, who must be told, who must consent and whether the business that earns the revenue is the business being bought.

The buyer is not buying last year's invoices. They are testing whether tomorrow's work can continue without an avoidable interruption.

A signed agreement can look reassuring in a data room. It can also conceal the issue. It may be in the name of a different group company. It may have been superseded by a supplier portal's terms. It may allow the customer to end the arrangement after a change of control. Or it may set out rates and quality standards while committing the customer to buy nothing at all.

For a €2m business and a €500m group, the consequence is the same. A material account needing approval, a revised agreement or a careful handover affects timing, buyer confidence and cash. Tooling, stock and capacity may be committed around revenue that is less certain than the sales report suggests.

Contract continuity belongs in normal management, not the final weeks of due diligence. Understand the evidence for each important revenue stream while there is time to solve a problem calmly.

Do not label all repeat business as contracted revenue. A framework can settle specifications, pricing and quality obligations, but may not promise future orders. Unless it creates a minimum purchase, take-or-pay commitment or other volume obligation, the committed revenue may sit in a purchase order, release, call-off or later amendment.

For every material customer, separate the commercial story from the evidence. What is ordered, for what period, by which company, on what terms and with what cancellation rights? Reconcile that answer to the forecast. A sensible twelve-month plan is not automatically a twelve-month contractual commitment.

• .The framework or master agreement, including all schedules and signed amendments
• .The live purchase orders, call-offs, releases and change orders that create specific work
• .The latest terms that apply through a procurement portal, quotation, acknowledgement or order of precedence clause
• .Evidence of acceptance, delivery, invoicing and any recurring disputes, credits or informal concessions

Your trading name is not the answer. Check the full legal name and company number where available on the agreement, purchase order, quotation acceptance, invoice and bank account. In a group, sales may be booked by one entity while manufacturing, people or customer support sit elsewhere. A historic reorganisation can leave a messy legal trail.

Check the customer side too. The procurement team, ordering company, payment company and end site can be different. That matters for notices, consent and credit. The account manager should name the customer contacts; finance should identify the debtor; legal advice may be needed on whose consent carries effect.

If the entity on the contract, the entity on the invoice and the entity in the proposed sale do not line up, treat that as an investigation to complete, not an assumption to carry forward.

The transaction structure changes the question. In a share deal, the company that signed the customer contract will usually remain the same contracting legal entity. Ownership changes, but the contract is not automatically transferred to a new company merely because its shares are sold. That is not the end of the review.

A change-of-control provision may require notice, consent or give the customer a termination right. The trigger can be direct or indirect and depends on the contract's definition of control. It may not mean automatic termination, but can still create leverage or a timetable problem. Review the wording, governing law and facts.

In an asset deal, the buyer may acquire the business through a different legal entity. Contracts may need assignment, novation or another agreed route, depending on the contract and governing law. Assignment does not automatically move both benefits and obligations. Novation is commonly used where the incoming party is to take over rights and obligations, but the parties and documentation matter. This is solicitor work, not an online template.

Look for assignment and subcontracting restrictions, change-of-control language, notice mechanics, termination rights, confidentiality, minimum volumes, price review, service credits, tooling and intellectual-property ownership, and step-in rights. Find clauses that could affect the buyer's ability to keep serving the customer on day one.

Look beyond the signed PDF. Portal acceptance, quality addenda, revised drawings, side letters and email chains can shape the live position. Identify the terms that apply and retain the evidence in one controlled place.

Illustrative engineering example, not a real client

A precision engineering company describes €1.4m of annual OEM work as contracted. The framework sets rates and quality requirements, but no minimum volume. Committed work sits in rolling orders, with only sixteen weeks open. The framework names the manufacturing company while invoices come from a later service company, and it requires a change-of-control notice. The account is not necessarily lost. It needs a clean entity explanation, realistic revenue classification, solicitor review and relationship plan before the buyer finds the gaps.

Keep this map short, evidence-led and current. Start with accounts that matter most by contribution, capacity exposure, strategic importance or transaction sensitivity. It should show what is true, what needs checking and who owns the next move. It does not replace legal advice.

A perfect consent process can still unsettle an account if the customer only knows the founder. For critical accounts, name a commercial owner, technical lead and operational contact. Agree who explains the ownership change, answers delivery questions and holds the next meeting.

That does not mean announcing a possible transaction prematurely. Timing and confidentiality matter. Prepare before communication is needed. The business should understand the account beyond one person: current work, engineering changes, tooling, margin pressure, delivery risk, contacts and the next conversation.

The founder or CEO may remain an important bridge. Introduce the next people where appropriate and let them solve real problems. The goal is not a ceremonial handover. It is customer confidence built through competent delivery.

• .Rank the top 10 to 20 customers by contribution, capacity commitment, strategic importance and transaction sensitivity, not revenue alone.
• .Gather the full contract chain for each account: agreement, schedules, amendments, portal terms, purchase orders, notices and key correspondence.
• .Reconcile each document to the legal entity on invoices, the debtor ledger and the entity expected to be sold or to acquire assets.
• .Separate framework coverage from live committed orders, then compare the evidence with the revenue forecast.
• .Flag assignment, novation, change-of-control, consent, notice and termination wording for qualified legal review.
• .Name a commercial owner, technical contact and executive sponsor for every critical relationship.
• .Create a controlled evidence folder and a simple red, amber or green status with a next action and date.
• .Meet weekly for thirty minutes until the material rows have a documented answer, owner and customer plan.

The strongest businesses do not wait for a buyer to expose uncertainty around their customer contracts. They know which company signed, what the customer has actually committed to, where consent or notice may arise and how the relationship will be carried through a change. That discipline improves more than sale readiness. It gives the management team a truer picture of future revenue, risk and customer dependency today.

You cannot make every account risk-free, and you should not pretend that every framework is guaranteed revenue. You can remove avoidable surprises. Build the evidence, get qualified advice on the actual contracts and make sure the customer sees a capable business on both sides of any ownership change. That is how contractual continuity becomes an asset rather than a last-minute negotiation.

A good contract file does not replace a good customer relationship. A good relationship does not replace a clear contract. Build both before a buyer asks for proof.
