Why Deals Collapse After Heads of Terms – And How to Prevent It

Reaching Heads of Terms feels like victory, but it is merely the halfway mark. Too many business owners assume that once the outline deal is agreed, momentum will carry the transaction through to completion. It will not.

A large proportion of SME deals collapse after Heads of Terms because the hard work begins at precisely the point owners finally take a breath. Completion requires scrutiny, resilience, and professional discipline. Without it, deals unravel quickly.

At EXITS.co.uk we see the same patterns time and again. Below is the reality of why deals fall apart – and more importantly, what you can do to keep your transaction alive.

The Most Common Reasons Deals Collapse After Heads of Terms

1. Due diligence uncovers surprises

Buyers expect normal commercial imperfections; what they cannot tolerate is hidden risk.Unreported liabilities, weak financial controls, poor customer contracts, or overstated earnings all derail confidence.

If due diligence reveals issues that were not disclosed upfront, buyers either reduce the offer or walk away entirely.

2. Trading performance slips

Post-HoT trading is closely monitored. If the business underperforms during the process, buyers rethink value, lenders lose appetite, and advisers start adding conditions. A declining P&L during due diligence is one of the fastest ways to kill a deal.

3. Poor preparation and slow responses

Deals collapse when the seller is not ready for the intensity of the process.Incomplete information, delayed answers, missing records, and general disorganisation sap buyer confidence. Momentum is everything. Lose momentum, and you lose the deal.

4. Emotional decision-making

Selling a business is deeply emotional.Some owners second-guess their exit, change their expectations, or become defensive under scrutiny. Erratic behaviour or moving the goalposts post-HoTs often undermines trust beyond repair.

5. Financing fails

Many SME buyers rely on external finance. If their funding partner becomes nervous during diligence, or if new conditions are imposed, the buyer may be forced to renegotiate or withdraw.

6. Legal documents become a battlefield

The Share Purchase Agreement (SPA) turns commercial agreements into legal reality.If the parties argue over warranties, indemnities, restrictive covenants, or completion mechanics, the deal often drifts into stalemate.

7. Key staff surprises

If buyers discover that key individuals are disengaged, planning to leave, or essential knowledge sits with one person only, confidence collapses immediately.

How to Prevent Deal Failure

1. Prepare thoroughly before going to market

You cannot “wing it” through a business sale.A professionally prepared business sale pack, financial normalisation, and pre-sale due diligence are essential.

This is where experienced brokers add real value. At EXITS.co.uk we insist on robust preparation because it dramatically increases completion rates.

2. Disclose issues early

No business is perfect. Buyers understand that.Problems become deal-killers only when they are discovered late.Early disclosure builds credibility, protects value, and prevents renegotiation.

3. Maintain strong trading performance

During the sale period, stability is everything.Owners must stay focused on operations while the advisers manage the deal process.Any downturn, however small, is scrutinised – so keep performance steady and predictable.

4. Keep emotions under control

Selling is stressful. But you cannot allow frustration or uncertainty to derail the process.A calm, commercially minded tone throughout negotiations reassures buyers and keeps the deal on track.

5. Work with advisers who know how to manage momentum

Deals collapse when timelines drift.Experienced advisers push diligence forward, close gaps, chase documentation, and keep the buyer engaged.

At EXITS.co.uk, our role is to minimise friction, maintain momentum, and protect the value agreed in Heads of Terms.

6. Ensure your legal team is deal-focused

Choose solicitors who specialise in business sales, not general practice.A poorly chosen lawyer can delay or even destroy a deal by being overly combative or slow.A deal-friendly legal team understands how to protect you without sabotaging negotiations.

7. Engage and retain key staff

Where appropriate, key employees should be reassured, incentivised, or briefed in a controlled and confidential way.Buyers need confidence that the team will support a smooth transition.

What It Really Takes to Get a Deal Over the Line

A deal completes when three things come together:

• robust preparation

• steady trading

• experienced deal management

Most business owners only sell once – buyers and advisers do this repeatedly. The imbalance shows. Trying to navigate the entire transaction alone or with inexperienced support often leads to missed details, avoidable delays, and failed deals. A properly managed process turns the Heads of Terms from a hopeful starting point into a successful completion.
