Frequently Asked Questions

Common questions from clients

How does Illinois's Freedom to Work Act change what my purchase agreement can include?
In a business acquisition context, the purchase agreement typically restricts the seller personally, but a buyer seeking to restrict key employees as part of the deal must account for these thresholds. The purchase agreement must use trade-secret protections, IP assignment, and non-solicitation provisions to cover the gap. Identifying which employees fall into which income tier before LOI shapes the protective architecture of the entire agreement.
How does Illinois's corporate income tax affect selling my Naperville business?
Combined with the federal capital gains rate, this makes the total tax burden on certain deal structures significantly higher than in no-income-tax states like Texas or Florida. The asset versus stock election and entity structure are material to your net proceeds.
What makes Naperville different from other Chicago suburban markets for a business sale?
Naperville's combination of household income, corporate presence, and owner-operated business density creates a buyer pool that includes both local and national PE firms, strategic acquirers with Midwest operations, search fund operators targeting stable cash-flow businesses, and family offices with preference for Illinois assets. The city's professional and manufacturing base means deal documentation often runs at institutional depth: thorough QoE, environmental Phase I for industrial assets, IP chain-of-title for technology deals, and payor contract management for healthcare practices. Sellers who prepare at institutional depth, who organize financials, environmental records, and customer contracts before the data room opens, compress diligence timelines and reduce the indemnity demands that follow from gaps discovered late in the process.
What does a business sale attorney do?
A business sale attorney handles the legal side of buying or selling a business. This includes structuring the deal, conducting or managing due diligence, drafting and negotiating the purchase agreement, and coordinating the closing.
Do I need an attorney for a small business sale?
Yes. A business sale involves a purchase agreement, allocation of liabilities, non-compete terms, and closing steps, and counsel can review each one before you sign.
What affects the cost of a business sale attorney
The cost depends on the size and complexity of the transaction. Acquisition Stars reviews your transaction and discusses fee structure during the initial engagement assessment, before any work begins.
Can you represent both the buyer and the seller?
No. We represent one party in a transaction, either the buyer or the seller.
How is Acquisition Stars different from a general business lawyer?
The firm's practice centers on M&A transactions, while a general business lawyer covers many areas of law. The work here focuses on structuring, due diligence, purchase agreements and closing.
How long does it take to sell a business?
No fixed period applies: from a signed letter of intent, due diligence, financing and the purchase agreement set the closing date, and preparation, marketing, and finding a buyer come before that.
Asset sale or stock sale: which is better for a seller?
Neither is better in every sale. An asset sale transfers selected assets, and a stock sale transfers the entity itself. The right choice depends on your entity type, liabilities, and tax position, so we review this early in the engagement.
What happens to my employees when I sell the business?
What happens to employees depends on whether the deal is an asset sale or a stock sale and on the terms the parties agree. We review employment agreements, benefit plans, and any change-in-control provisions as part of the sale.
How an earnout or seller note works
An earnout ties part of the purchase price to the business hitting agreed performance targets after closing. A seller note has the buyer pay part of the price over time, with the seller acting as a lender. Both shift risk back to the seller and require careful negotiation of the metrics, payment terms, and default remedies.
How do I protect myself from claims after the sale closes?
Post-closing liability is managed through negotiation of representations and warranties, indemnification caps, basket thresholds, survival periods, and escrow amounts. We negotiate each of these terms on your behalf as part of the sale, whether you are selling directly to a buyer or through a broker-managed process.
How do I choose a lawyer to sell my business?
Choose a lawyer to sell your business based on sell-side transaction experience, not general business law credentials. Confirm the attorney can evaluate earnout, rollover equity, and seller-financing terms well enough to tell you which provisions are standard and which put your proceeds at risk, not just draft the purchase agreement. Also confirm availability during due diligence and how fees scale with deal size before you engage.
Can you sell a business without a lawyer?
An owner can negotiate a sale without a lawyer. The purchase agreement, indemnification terms, and escrow structure are easier to review with counsel before you sign.
What are red flags when hiring a lawyer to sell a business?
The clearest red flags: an attorney who will not say who handles your deal, has no sell-side experience, cannot explain earnout or rollover risk in plain terms, quotes a price before reviewing your deal, or will not put the engagement scope in writing. See the red flags section above for the full list and what to ask instead.
Does Acquisition Stars only represent sellers, or buyers too?
Acquisition Stars represents both buyers and sellers in business sale transactions, though never both parties in the same deal. The firm's sell-side experience, including evaluating earnout, rollover equity, and seller-financing terms, applies whether you are the party selling or the party structuring an offer to buy.
How do Illinois non-compete laws affect business sale transaction law transactions?
Illinois bars a covenant not to solicit with an employee unless the employee's actual or expected annualized earnings exceed $45,000 a year, a figure that rises to $47,500 in 2027, $50,000 in 2032 and $52,500 in 2037, and a covenant made in violation is void. (820 ILCS 90/10)
What are the Illinois tax considerations for selling a business?
Illinois taxes a corporation at 7% of its net income for taxable years beginning on or after July 1, 2017. (35 ILCS 5/201) Illinois also imposes a personal property tax replacement income tax of 2.5% of net income on a corporation other than an S corporation, and of 1.5% of net income on a partnership, trust or S corporation. (35 ILCS 5/201)
Does Illinois have a bulk sales law that affects business acquisitions?
Under 35 ILCS 120/5j, if a taxpayer, outside the usual course of business, sells or transfers the major part of its stock of goods, its furniture or fixtures, its machinery and equipment, or its real property, the purchaser must file a notice of the sale or transfer with the Illinois Department of Revenue no later than 10 business days before the sale or transfer. (35 ILCS 120/5j) A buyer who does not file on time can be personally liable for the seller's unpaid taxes, up to the reasonable value of the property acquired. (35 ILCS 120/5j)
What can I expect during an initial consultation?
During a confidential initial consultation, we discuss your transaction, review your current situation, assess challenges specific to Illinois, and outline a path forward. We explain our process, answer your questions, and determine whether we are the right fit.
Do you work with companies outside of Naperville?
Yes. Acquisition Stars represents clients nationwide and coordinates with local counsel where state-specific requirements apply.

M&A Market: Naperville & the Chicago Metro

Chicago is the Midwest's M&A powerhouse, with deep deal activity in manufacturing, food & beverage, financial services, and healthcare. The city's central location and transportation infrastructure make it a hub for logistics and distribution company acquisitions. Chicago's robust private equity community - including firms like GTCR, Madison Dearborn, and Duchossois Capital - drives significant lower middle-market deal flow.

Top M&A Sectors Near Naperville

  • Manufacturing
  • Food & Beverage
  • Financial Services
  • Healthcare
  • Logistics & Distribution

Deal Environment

Chicago offers a balanced deal market with strong fundamentals - valuations are more reasonable than coastal markets while target quality remains high. The region's manufacturing base creates consistent opportunities for PE-backed platform builds.

Why Acquire in the Chicago Area

The Chicago metro area's diversified economy and central location make it ideal for platform acquisitions with national expansion potential. The region's deep talent pool in engineering, finance, and operations supports post-acquisition growth.

Naperville M&A Market Insight

Naperville consistently ranks among the wealthiest suburbs in the Midwest and in the country by household income, a reflection of the professional-class population built around corporate relocations, major employers in technology and financial services, and a thriving owner-operated business community. The Naperville seller base skews toward professional services firms including engineering, accounting, and consulting practices, manufacturing and industrial operations serving the broader Midwest supply chain, technology and software businesses, and healthcare services organizations including specialty practices and outpatient care facilities.

Common Deal Scenarios

1

Professional Services Firm Sale with Post-2022 Non-Compete Constraints

Employees above the threshold face enforceability scrutiny on reasonableness grounds. Buyers should identify key revenue-generating employees by income level before LOI, because that analysis shapes what protective provisions are legally available.

2

Manufacturing or Industrial Business Sale

Naperville and the western suburbs support a diverse manufacturing and industrial base that generates consistent sell-side deal flow. PE buyers pursuing manufacturing roll-ups in the Chicago suburbs run deep operational diligence and push for earnouts tied to EBITDA metrics. Sellers who prepare QoE-ready financials, organize environmental documentation, and understand their working capital cycle before going to market preserve value that less-prepared sellers surrender during diligence.

3

Healthcare Services or Technology Business Exit

Naperville's healthcare services and technology businesses reflect the suburb's educated, affluent population and its proximity to major research hospitals and the Chicago technology ecosystem. Healthcare practice sales require MSO structuring for Illinois CPOM compliance, payor contract change-of-control management, and provider credentialing timelines.

Why Naperville for M&A

Naperville's position as the leading high-income Chicago suburb creates a sell-side market where the businesses are real, the buyers are sophisticated, and the legal work has to match both. The depth of the buyer pool, from PE firms to family offices to search funds, means sellers face institutional diligence standards regardless of deal size. Counsel who understands Illinois's specific legal framework, not a national template applied to an Illinois deal, is the difference between a clean closing and a prolonged diligence process.
