The Post-Closing Obligations Founders Forget to Negotiate

Closing day feels like the finish line. The wire clears, the documents are signed, and the deal is done. But for most founders, closing is not the end of the transaction — it is the beginning of a new set of obligations that can last months or years.

The founders who are surprised by what comes after closing are the ones who did not negotiate those terms carefully before they signed.

Transition Services

Most buyers require the seller to provide transition support after closing — helping the new owner understand operations, introduce key relationships, and transfer institutional knowledge. The scope, duration, and compensation for this work vary widely.

What founders often miss is that transition obligations are negotiable. The length of the transition period, whether it is compensated, what happens if the buyer extends it, and what constitutes a reasonable request — all of these should be defined in the purchase agreement. An open-ended transition obligation with no defined end date is a problem that does not surface until after closing.

Non-Compete and Non-Solicitation Agreements

Most M&A transactions require the seller to sign a non-compete agreement restricting them from starting or joining a competing business for a defined period — typically two to five years. Non-solicitation agreements restrict the seller from poaching employees or clients from the business they just sold.

These provisions are standard. What founders forget to negotiate are the scope, geography, and duration. A non-compete that is too broad can effectively end a founder’s ability to work in their own industry. Negotiating reasonable limitations — on what counts as a competing business, what geographic markets are covered, and how long the restriction runs — has to happen before the purchase agreement is signed.

Indemnification Obligations

Even after closing, sellers remain on the hook for breaches of representations and warranties made in the purchase agreement. If a buyer discovers post-closing that something the seller represented was inaccurate — a financial statement, a contract term, an IP ownership claim — the seller may be required to indemnify the buyer for resulting losses.

Indemnification obligations have time limits and caps — but those limits are negotiated, not automatic. Sellers who accept the buyer’s first draft often end up with indemnification periods and caps that are far more favorable to the buyer than necessary. Understanding what you are agreeing to indemnify, for how long, and up to what amount is essential before you sign.

Earnout Obligations

If your deal includes an earnout, closing is the beginning of a performance period that determines how much of your purchase price you actually receive. Earnout periods typically run one to three years and require the seller to hit defined revenue, EBITDA, or operational targets.

What founders forget to negotiate are the operational protections that give them a fair shot at hitting those targets. Without defined protections, the buyer can make post-closing decisions — changing pricing, shifting resources, restructuring the sales team — that make it functionally impossible to achieve the earnout metrics. Negotiate those protections before closing, not after you have missed a target.

Tax Filings and Cooperation Obligations

Sellers are often required to cooperate with the buyer on tax matters following closing — assisting with pre-closing tax returns, responding to audits that relate to periods before the sale, and supporting any tax elections made as part of the deal structure. These obligations can extend for years. Know what you are agreeing to, how long the obligation runs, and whether you will be compensated for significant time commitments.

The Negotiation That Happens Before You Sign

Every post-closing obligation in this list is negotiable before the purchase agreement is executed. After closing, the leverage is gone. Founders who understand what they are committing to post-closing — and who push back on terms that are unreasonably open-ended — protect themselves from obligations that outlast the deal itself.
