“Discovering that your commercial contracts require customer consent to transfer is a deal complication that belongs in the pre-market planning stage, not the due diligence stage.”
Assignment Clauses: The Hidden Deal Risk
Most commercial pest control service agreements contain an assignment clause — a provision that governs whether the contract can be transferred to a new entity without the customer's consent. In an asset sale, the seller is transferring their contract rights to the buyer — which constitutes an 'assignment' under contract law. If the assignment clause requires customer consent (which is very common in commercial contracts), the seller cannot guarantee transfer of the contract without approaching each commercial customer and asking them to sign a consent. This is one of the most underestimated risks in pest control business sales, particularly for businesses with significant commercial revenue. Discovering at the LOI stage that 40% of your commercial revenue requires customer consent to transfer is a significant deal complication.
Three Types of Assignment Provisions
Commercial service contracts typically contain one of three types of assignment provisions: (1) Freely assignable — the contract can be assigned by either party without the other's consent. This is the most seller-friendly outcome. (2) Assignable with notice — the assigning party must notify the other but doesn't require affirmative consent. Common in multi-year commercial contracts with large institutional customers. (3) Consent required — the assignment requires written consent from the non-assigning party. Most common in customer-friendly commercial contracts. (4) Anti-assignment clause — the contract cannot be assigned at all without creating a default. This is rare but exists and is problematic. For a stock sale (selling the company entity itself rather than its assets), assignment clauses often don't apply — because the entity hasn't changed, only its ownership. This is one of the reasons stock sales are sometimes preferred when commercial contract transferability is a concern.
Reviewing Your Contract Portfolio Before Going to Market
Every pest control business with meaningful commercial revenue should conduct a contract audit before listing. For each commercial customer: (1) Pull the signed service agreement. (2) Identify the assignment clause. (3) Categorize each contract as: freely assignable, consent required, or no written agreement. (4) Calculate what percentage of your commercial revenue is freely transferable vs. consent-required. This audit takes a few hours but is essential. A seller who knows their contract transferability profile can structure the deal (asset vs. stock) and the buyer communication strategy accordingly. A seller who doesn't know goes into the LOI stage with a major unknown.

The Consent-to-Assign Process for Commercial Customers
If your commercial contracts require customer consent to assign, the process: (1) The buyer should be aware of this requirement before signing the LOI — consent to assign should be listed as a closing condition for each material commercial contract. (2) The timing of customer contact is critical — approach commercial customers too early and you create a premature confidentiality breach. Too late and you're scrambling to get signatures at closing. Standard timing: begin consent conversations after LOI execution, once both parties are committed to the transaction. (3) The seller typically makes the customer approach — the seller has the existing relationship and can frame the conversation as a positive development. (4) Some buyers offer customer retention incentives in exchange for consent — a service discount, a pricing guarantee, or a service enhancement to sweeten the transfer consent request.
Month-to-Month Commercial Relationships: The Consent Gray Zone
Many pest control businesses have commercial customers on informal or month-to-month arrangements with no written agreement — just an established service routine and a recurring invoice. These relationships are valuable (often highly reliable revenue) but create a legal gray area in assignments. Without a written contract, there's nothing to assign — the buyer is simply starting a new service relationship with each informal customer. The risk: informal commercial relationships are easier for customers to walk away from when they hear about the ownership change. They have no contractual obligation and no specific assignment provision to honor. Best practice: in the 12–18 months before sale, formalize informal commercial relationships with written service agreements, even simple one-page documents that include an assignment provision. Formalizing creates both a legal framework for transfer and a signal of operational professionalism.
Change of Control Clauses in Commercial Contracts
Some sophisticated commercial customers (property management companies, government facilities, corporate accounts) insert change of control clauses into their service agreements — provisions that give them the right to terminate the contract (or renegotiate terms) upon a change in ownership of the service provider. These are different from assignment clauses: assignment clauses govern the seller's right to transfer; change of control clauses give the customer an exit right when ownership changes regardless of who initiates the transfer. Change of control provisions are most common in government contracts, multi-year property management agreements, and any contract negotiated by a large company's procurement department. Identify any change of control provisions in your contract portfolio before going to market — they represent a material risk to commercial revenue continuity post-close.
Protecting the Buyer and Seller in the Purchase Agreement
The purchase agreement should address commercial contract transferability explicitly: (1) Seller representation — the seller represents that all customer contracts are assignable (or, if not all are freely assignable, the disclosure schedule lists those requiring consent). (2) Closing condition — the buyer's obligation to close is conditioned on receiving assignment consents for a defined threshold of commercial revenue (e.g., 90% of contracts by dollar value). (3) Price adjustment mechanism — if consent isn't obtained for a defined percentage of commercial contracts, the purchase price adjusts downward. (4) Post-close cooperation — the seller agrees to continue assisting with customer consent solicitation for a defined period after close if consents weren't complete at closing. These provisions protect both parties — the buyer gets commercial revenue certainty, and the seller has a defined path to full proceeds.
