We are structuring our transaction as a Section 453 installment sale to defer taxes, but we want to secure the note using our proprietary AI software and operational workflows as collateral instead of just physical assets. How do we legally structure this security agreement and monitor it?

Securing an installment sale under Section 453 requires thinking beyond traditional physical assets, especially for an AI-powered service business. If the buyer defaults on their payments, physical equipment holds little value compared to your proprietary software, data models, and automated workflows. You must structure a comprehensive security agreement that grants you a first-priority lien on all intellectual property, source code, and operational systems. This lien must be filed under a Uniform Commercial Code filing, specifically targeting these intangible assets. To make this operational, require the buyer to place a complete copy of the software source code and operational documentation into an independent escrow account. If they miss an installment payment and fail to cure it within fifteen days, the escrow agent must immediately release the code and access credentials back to you. You should also maintain visibility by requiring the buyer to share their weekly Scorecard. This allows you to monitor leading indicators of financial distress, such as declining pipeline volume or escalating customer churn, long before a payment is missed. By tying the security agreement directly to the digital assets that run the business, you ensure that you can quickly reclaim and operate the business if the buyer defaults on their tax-deferred installment payments.
