An earnout is a contractual provision where a portion of the business purchase price is deferred and paid only if the business achieves specific performance milestones after closing. Earnouts bridge valuation gaps — sellers who believe the business will continue growing accept some deferred risk; buyers who are uncertain about post-close performance pay less upfront while retaining the ability to pay more if results materialize.
Common Earnout Structures
Earnouts are typically measured over 1–3 years post-closing on metrics such as: annual revenue (exceeding a threshold), gross profit, EBITDA, or specific operational metrics (client retention rate, contract renewals). For example: 'Seller receives $200,000 per year for 2 years if annual revenue exceeds $2M in each year.' Payment schedules can be annual or quarterly.
Negotiating Earnout Terms
Sellers should negotiate: control over the operational and financial decisions that drive the earnout metric, clear accounting definitions for how the metric is calculated, audit rights to review post-close financials, and acceleration provisions if the buyer materially changes the business strategy. Buyers who gain full operational control post-close and then manage the business in ways that reduce earnout payments have created one of the most common post-acquisition disputes in small business transactions.
When earnouts are appropriately structured with protective provisions for the seller, they can represent fair additional consideration for a business sale. When they are loosely defined and buyer-controlled, they represent deferred consideration the seller may never receive.

A simple Illinois close calendar
Plan six to twelve months from cleanup to close on a prepared Main Street deal. Start CBS-1 and any Chicago or Cook notices at letter-of-intent, not the week of funding. Landlord consent often takes longer than the lender.

Most prepared Main Street sales take about six to twelve months from cleanup to close. License transfers, landlord consent, and SBA underwriting add weeks.
CBS-1 is the Illinois bulk-sale notice. File it at least ten business days before an asset transfer that meets the statute. Late filing can put Illinois tax risk on the buyer.
