Carve-out customer contract assignments are the workstream that decides whether the revenue actually arrives at Newco on Day One. Most carve-out diligence focuses on cost. The deal value sits on the revenue side, and the revenue base only transfers cleanly when the customer contracts are properly assigned, notified, or replaced. Disciplined carve-out advisory reads every clause, codes the consent risk, and runs a structured customer campaign that protects the revenue from the first day.
A carve-out moves a business unit out of the seller and into a new legal entity. Every customer contract that supports that business unit was signed by the seller, not by Newco. The legal counterparty changes at closing. The customer may have no obligation to recognize Newco as the new counterparty unless the contract is properly assigned or replaced.
The risk is rarely that customers refuse outright. The risk is friction. A customer that has to retrain its procurement team, update vendor master records, run a fresh due diligence on Newco, and renegotiate terms takes time. During that time, payments slow down, orders pause, and renewal conversations turn delicate. The disciplined buyer measures the friction in the diligence model.
The customer contract task therefore has two dimensions. Legal mechanics, which is about clauses and consents. And customer relationship, which is about how the change is communicated. Both have to be planned. The mapping discipline overlaps with the broader carve-out Day One readiness approach.
Customer contracts fall into three clause categories. Silent contracts allow assignment without notice. Notification clauses require notice but not approval. Consent clauses require customer approval, sometimes at sole discretion. Each clause carries a different operational consequence on Day One.
Silent contracts are the easiest. The legal assignment happens at closing through the SPA and the customer is told as a courtesy after the fact. Notification clauses require a written notice issued in a defined window before or after closing. Consent clauses require an active customer signature on an assignment agreement or a fresh contract. The volume of consent clauses is the work driver.
The disciplined buyer codes every contract in diligence. Top customers by revenue, by gross margin, and by strategic importance are coded first. The long tail can usually be handled with a standard notification campaign. The top 20 customers usually need a tailored approach with named owners on both the seller and buyer side. The discipline mirrors the broader TSA third-party vendor consents approach.
A small fraction of customer contracts contain anti assignment clauses that bar transfer entirely. These clauses often appear in regulated industries, in government contracts, and in master agreements with strategic suppliers. The anti assignment clause is sometimes absolute and sometimes carries a change of control trigger that applies even when the contract is silent on direct assignment.
Three workarounds appear. A novation, where the original contract is replaced with a fresh agreement between Newco and the customer on the same terms. A subcontract structure where the seller remains the named counterparty and subcontracts the work to Newco. And a fresh contract under new commercial terms. The right answer depends on the customer relationship and the regulatory environment.
Government contracts are a category of their own. Federal contracts in the US, central government contracts in the UK, and regulated procurement in the EU all have specific assignment procedures. The work usually requires specialist counsel and a longer timeline. The disciplined buyer surfaces these contracts early and treats them as separate workstreams.
The diligence model carries three numbers for the customer book. Revenue at risk, defined as the dollar value of contracts with consent clauses. Probability weighted churn, defined as the share of that revenue likely to delay or churn during the transition. And working capital impact, defined as the cash flow lag from delayed payments and slower order cycles.
Historic data from similar carve-outs suggests churn from contract assignment friction runs at 2 to 5 percent of revenue in the first year. Payment timing also slows. A typical Newco sees Days Sales Outstanding extend by 5 to 15 days in the first 90 days while customers update vendor master records and update banking instructions. Both effects belong in the cash flow model.
The disciplined buyer also identifies the strategic customers whose loss would be material to the deal thesis. These customers receive a tailored approach. A pre signing courtesy call from the seller's senior commercial leader. A coordinated Day One package with new banking details, new contract paper, and a relationship transition plan. And a named buyer side executive responsible for the relationship from Day One. The pattern overlaps with the broader Day One customer and vendor communication approach.
The customer notification campaign is built before closing and launched at signing or closing depending on the deal structure. A typical campaign has three waves. Wave one is the top 20 customers, contacted personally by the seller's senior commercial leader in coordination with Newco's incoming executive. Wave two is the top 200 customers, contacted by relationship managers with a tailored letter. Wave three is the long tail, contacted with a standard letter and a digital onboarding portal.
Each wave has a defined script. The script addresses the customer's most likely concerns. Will the service continue. Will the people be the same. Will the price change. Will the contract terms change. Will the banking details change. The disciplined script answers these proactively. The customer does not need to ask.
The campaign is tracked. A weekly dashboard reports contacts made, responses received, assignments signed, and issues escalated. The data drives the operating partner's view of revenue continuity in the first 90 days. Specialist support on this work is part of the Day One Readiness Program for buyers without internal capacity.
Revenue continuity on Day One requires more than legal assignment. The order to cash machinery needs to work. Customers need to be able to place an order, receive an invoice in Newco's name, and pay into Newco's account. Each of these steps has its own dependency on the customer's vendor master record.
The disciplined buyer plans the order to cash transition explicitly. The Day One invoicing system is configured before closing. The new banking instructions are communicated 30 days before Day One. A reconciliation process handles payments that arrive late at the seller's old account in the first 60 days. A revenue continuity owner reports daily for the first two weeks and weekly thereafter.
The TSA bridges the gap where the order to cash transition is not yet complete. The seller continues to invoice in its own name and remits the cash to Newco. The structure is operationally heavy and should be planned for the shortest possible period. A long order to cash TSA creates dependency on seller systems that the buyer cannot fully control. The pattern overlaps with the broader carve-out 100 day plan.
