An M&A closing can look deceptively simple from the outside. The buyer wires the purchase price, the seller signs over the business, and everyone celebrates.
The reality is that the basis for a successful closing is built over the entire transaction. In order toget to closing day, the parties may need to complete dozens of legal, financial, tax, operational, and logistical tasks.
Many depend on third parties who do not share the deal team's urgency. Waiting until the final week can delay or derail an otherwise sound transaction.
Imagine a business owner selling a manufacturing company. The parties sign the purchase agreement and schedule closing for Friday.
On Wednesday, they learn that the landlord has not approved the lease assignment, a former lender still has a blanket UCC lien against the company's assets, the buyer's bank needs additional insurance documentation, the buyer has not finished setting up its new payroll system for the employees it plans to hire at closing, and the parties have not agreed on the estimated working capital or final funds flow.
None of these problems is unusual. But no one identified the dependency early enough or made one person responsible for resolving it.
This article addresses the operational side of an M&A transaction: the work that buyers, sellers, and their advisors should perform throughout the process so that closing day becomes the culmination of the deal rather than a last-minute fire drill.
The short answer: Buyers and sellers make closing easier by identifying every condition, consent, tax issue, payoff, financing requirement, financial calculation, and transition task early; assigning each item to a specific person; and testing closing readiness before money is scheduled to move.
Closing is the point at which the transaction becomes effective, ownership changes hands, and the purchase price is paid or delivered as the agreement requires. Some deals are signed and closed at the same time.
In others, the parties sign the purchase agreement first and close days or months later after specified conditions have been satisfied.
The distinction matters. A simultaneous signing and closing avoids an interim period, but it requires the parties to complete virtually every closing task before anyone signs the purchase agreement.
A separate signing and closing lets the parties commit to the transaction while they finish financing, obtain regulatory approvals or third-party consents, and satisfy other conditions. It also creates a period during which the seller must continue operating the business under agreed restrictions and both sides remain exposed to the possibility that the deal will not close.
The purchase agreement should identify the conditions each party must satisfy. But the agreement is not a project plan.
It will not automatically tell the accountants when to complete the tax projection, remind the landlord to sign a consent, or confirm that a lender has prepared a UCC termination statement. Those tasks belong on a separate closing checklist.
Pro tip: Start converting the negotiated deal terms into an operational deal plan while the purchase agreement is being drafted. Waiting for a final agreement wastes the period when many third-party and financial workstreams should already be moving.
Making this sort of plan outside the purchase agreement can also inform the purchase agreement’s own contents and make sure material terms specific to the deal are not omitted.
A good closing checklist identifies every document, approval, payment, filing, and other action required to close. It should state who owns each item, who must review or sign it, its deadline, and any task that must occur first.
The lawyers often maintain the master checklist, but completing the transaction requires active participation from the business principals, accountants, lenders, brokers, insurance professionals, and sometimes landlords, customers, vendors, and government agencies.
The checklist should begin early and evolve with the deal. Due diligence may reveal a missing corporate approval or an old lien. Negotiation of the purchase agreement may add an escrow, a seller note, or a special consent requirement. The buyer's lender may impose requirements that do not appear in the purchase agreement at all.
The most useful status calls focus on exceptions: what remains open, what is late, what depends on a third party, and what could prevent funding. A checklist marked mostly “in process” provides little comfort if a few unresolved items can stop the closing.
For both sides, the checklist prevents a required signature, release, consent, or delivery from surfacing too late.
The headline purchase price does not tell the seller how much cash will be available to the seller after closing. A seller may need to repay debt, pay transaction expenses, fund an escrow, wait for deferred payments, and reserve cash for taxes. These amounts can materially change whether the deal meets the seller's financial goals.
The seller should ask its tax advisor early-on for a written projection using the proposed structure and price, and update it whenever material assumptions or deal terms change.
Depending on the transaction, the analysis may need to address:
In many business asset acquisitions, both buyer and seller report the allocation on IRS Form 8594. That allocation affects the seller's character of gain and the buyer's tax basis and future depreciation or amortization. It therefore has real economic value to both sides and should not be treated as a tax form to complete after the business terms have already been fixed.
Seller notes and contingent payments require particular attention. A seller should not assume that “paid later” necessarily means “taxed later” in every respect. The installment-sale rules, imputed-interest rules, and treatment of particular assets can produce different results. The seller's CPA should model the expected timing of both cash and taxes rather than offering only a total estimated tax number.
A useful projection starts with the purchase price and separately shows debt payoff, transaction expenses, escrow or holdback, deferred amounts, and estimated taxes. The result should show how much cash the seller expects at closing and in each later period.
Buyers also need to understand their expected tax basis, amortization and depreciation benefits, and reporting obligations. Early analysis may identify enough value to support a negotiated solution for both sides.
Pro tip: Do not wait for a nearly final purchase agreement before requesting the tax projection. By then, the LOI, price, structure, and payment mechanics may have made the most important tax choices difficult to change.
Contracts, leases, licenses, permits, and financing documents may restrict an assignment or require consent to a sale or change of control. An asset sale often requires individual assignments of contracts. An equity sale may avoid some assignment provisions, but many agreements expressly require consent when ownership or control changes.
The parties should create a consent schedule during diligence that answers four questions:
Timing requires judgment. Contacting a major customer or employee too early can expose a confidential transaction and create instability. Waiting until the last week may give that person leverage or make an on-time closing impossible.
The purchase agreement should distinguish between consents that are absolute closing conditions and those the parties will continue pursuing after closing.
Landlords deserve special attention. A buyer may need a lease assignment, a change-of-control consent, an extension, an estoppel certificate, or an entirely new lease. The landlord may request financial information, a larger deposit, a guaranty, reimbursement of legal fees, or changes to the lease. None of this moves on the deal team's timetable.
The same principle applies to governmental approvals and regulated licenses.
The parties should confirm early whether a license transfers automatically, requires notice, requires approval, or must be reissued to the buyer. A late-discovered need for a buyer to obtain a new license is a common culprit in a delayed closing.
Pro Tip: It can be possible to make arrangements that would allow certain seller contracts to be assigned after closing where a consent is too sensitive to solicit prior to closing or where there simply is not time.
How to make this work without violating contractual obligations of the seller is a case-by-case analysis that seller’s and buyer’s counsel can collaborate on and plan for. Likewise, creative transition service arrangements can be used in appropriate cases to facilitate closing over an unresolved or pending licensing issue.
The buyer generally expects to receive the purchased assets free of liens. The seller usually expects the transaction debt and personal guarantees to disappear when the sale closes. Accomplishing both requires more than calculating a loan balance.
The seller should identify all secured debt, equipment financing, vehicle loans, credit lines, merchant cash advances, and other obligations that may encumber the seller’s assets. UCC and other lien searches should be completed early enough to investigate unexpected filings.
For each payoff, the closing team may need:
An old UCC filing does not always mean money is still owed. It may mean a prior lender failed to terminate its filing. Unfortunately, locating the right person and obtaining a termination can take time, particularly if the lender was acquired or the account closed years ago.
Buyers should verify the release mechanics instead of relying solely on a seller's promise that the debt will be paid. Sellers should confirm that the closing process releases both the collateral and any personal obligation. These are aligned interests, even though the parties approach them from different sides.
Just because a buyer has a financing commitment or term sheet does not mean the funds are ready to wire to the seller at any time. The buyer's lender may require its own diligence, underwriting approval, equity contribution, loan documents, guarantees, collateral filings, appraisals, quality of earnings analysis, insurance certificates, landlord documentation, and evidence that every acquisition condition has been satisfied.
The buyer should integrate the lender's checklist into the transaction checklist and identify any requirement that depends on the seller. The seller should understand the major financing milestones and avoid assuming that financing is solely the buyer's private workstream.
If the lender needs seller financial statements, organizational documents, lien information, a landlord waiver, or changes to the purchase agreement, delay by either side can delay everyone.
The parties should understand whether the purchase agreement contains a financing condition and what happens if the lender does not fund. Those rights do not replace practical coordination.
Between signing and closing, the seller typically agrees to operate in the ordinary course and to refrain from specified actions without the buyer's consent. The objective is reasonable: the buyer agreed to purchase a particular business and does not want that business materially changed before ownership transfers.
The restrictions can nevertheless affect normal operations. The seller may need consent to enter a significant contract, increase compensation, hire or terminate certain employees, incur debt, make distributions, settle litigation, or purchase equipment.
The management team needs to know the rules, and the parties need a practical method for obtaining prompt consent.
At the same time, the accounting work continues. If the deal includes a working-capital adjustment, the seller generally prepares an estimated closing statement before closing.
The parties must apply the accounting principles negotiated in the purchase agreement, resolve questions about unusual items, and incorporate the estimate into the funds flow.
This is not a calculation to begin the night before closing. A disagreement about whether a liability belongs in debt, transaction expenses, or working capital can change the closing payment and delay funding.
Employee transitions should be planned well before closing. In an asset sale, the seller may terminate employees at closing and the buyer may offer new employment. In an equity sale, employment may continue with the same legal entity, but payroll, benefits, reporting lines, policies, and employee communications may still change.
The parties should decide which employees the buyer expects to retain, when offers and communications will occur, and who is responsible for final wages, accrued paid time off, bonuses, commissions, severance, payroll, benefits, retirement-plan issues, personnel records, and any required notices. The answers vary by deal and by state, so employment and benefits advisors may need to be involved.
The buyer should also confirm that its payroll system and benefit arrangements will be ready when responsibility changes. A buyer that owns the business on Friday but cannot run payroll on Monday has an immediate workforce problem.
The communication plan requires judgment as well: communicating too early can destabilize the workforce, while waiting too long can leave employees uncertain and the parties unprepared.
The funds-flow memorandum explains where every dollar goes at (and sometimes after) closing. It may include the cash purchase price, lender funding, buyer equity, debt payoffs, transaction expenses, escrow deposits, holdbacks, broker fees, and the amount wired to each seller.
The parties should circulate a draft several days before closing and reconcile it to the transaction documents. Each recipient and account should be confirmed independently. Because business email compromise frequently targets wire transfers, any late change to wiring instructions should be verified through a trusted telephone number, not a reply to the email requesting the change.
Operational control also changes hands at closing. The parties should plan access to accounts, facilities, systems, records, and corporate documents, as well as communications, payroll, benefits, insurance, signing authority, and the seller's post-closing role.
This planning protects both sides. The buyer can begin operating without interruption. The seller avoids being treated as the informal solution to every problem after ownership has changed.
Several days before the scheduled closing, the core team should conduct a focused readiness review. This is different from a routine status call. The question is no longer whether people are working on their assignments. The question is whether every condition to funding can actually be satisfied on time.
The team should confirm:
Anything unresolved should have a named owner, a deadline, and an agreed alternative. The parties may waive a condition, escrow funds, use a post-closing covenant, or move the closing date. The decision should be documented, not improvised while everyone waits for a wire.
On closing day, the lawyers confirm that the conditions have been satisfied or waived, the parties authorize release of signatures, funds move according to the agreed funds flow, and the team confirms that the transaction has closed. If the earlier work was done properly, closing day should contain very few surprises.
As soon as the deal structure and principal terms begin to take shape. Consents, tax analysis, financing, lien releases, and financial calculations often take longer than expected. Starting early also lets the parties account for these issues while they still have meaningful negotiating flexibility.
Transaction counsel often maintains the master checklist, but every item should have a business owner. Lawyers cannot obtain the landlord's consent, complete the tax projection, satisfy the buyer's lender, or plan employee communications without active participation from the appropriate people.
Frequent causes include financing conditions, third-party consents, unresolved liens, missing organizational approvals, disagreements over working capital or closing payments, incomplete ancillary documents, and delayed signatures. The common thread is usually not that the issue was unknowable, but that it was identified or assigned too late.
The purchase price does not equal cash available to the seller. A projection helps the seller understand taxes, debt payoff, transaction expenses, escrow, deferred payments, and the timing of actual cash receipts. It can also identify deal terms that should be renegotiated before they become fixed.
The parties confirm that the conditions to closing have been satisfied or waived, release previously signed documents, transmit funds according to the agreed funds flow, and confirm that ownership has transferred. Most substantive documents and calculations should already be complete.
The best closings are uneventful. That does not happen because the transaction was simple. It happens because buyers, sellers, and their advisors identified the dependencies early, assigned responsibility, and resolved problems while there was still time to solve them.
For sellers, disciplined preparation helps protect the expected value of the transaction and clarifies what will actually remain after debt, expenses, escrows, deferred payments, and taxes. For buyers, it helps ensure that financing is available, liens and consents are addressed, and the acquired business can operate on the first day under new ownership.
If you are considering a sale or acquisition, the closing plan should begin long before closing week. Paracuellos Law Group helps buyers and sellers structure and manage M&A transactions from the first major term through the final transfer of funds and ownership.
