The 12-Month Exit Preparation Plan for Engineering Owners

How to significantly increase your chances of creating an advantageous deal structure and sell for a premium price.

Selling an engineering business isn’t something you should do on a whim — yet far too many owners treat it like a transactional event. The ones who succeed? More often than not, they’ve done the strategic ground work to prepare for sale. 

This 12-month exit preparation plan lays out exactly what you need to fix, prioritise, and invest in if you want buyers to compete — not negotiate you down.

Month 1–2 — Honest Business Health Check

Ask the brutal questions:

• What percentage of revenue comes from your top 3 customers?
  
• Can the business function without you?
  
• Are contracts documented?

“Owners often tell me they already know their numbers — but buyers want verified, detailed, and defensible figures,” says John Southern, Managing Director at Ventura Business Brokers. “If you’re not prepared for forensic scrutiny, you’re already at a disadvantage.”

Month 3–4 — Clean Up Your Financials

Buyers don’t buy fuzzy accounts. They buy certainty.

Focus on:

• Up-to-date P&L and balance sheets
  
• Monthly management accounts
  
• Legitimate EBITDA adjustments

“Adjusted EBITDA is one of the biggest blind spots I see. Owners count profit — buyers count sustainable profit,” John explains. “Getting this right can add multiple turns to valuation.”

Month 5–6 — Operational Confidence Boost

Buyers pay for continuity, not chaos.

Do you have:

• Standard Operating Procedures (SOPs)?
  
• Documented pricing logic?
  
• A clear managerial hierarchy?

“If the business only lives in your head,” John warns, “the buyer will price that risk into their offer — usually £100,000s lower than you’d hoped.”

Month 7–8 — Customer and Supplier Review

A great business to run isn’t always a great business to sell.

Assess:

• Customer concentration risk
  
• Contract renewals
  
• Supplier dependencies
  

Small tweaks here can have an outsized impact on valuation.

Month 9–10 — Rehearse Due Diligence

Most deals die in due diligence, not at offer stage.

Run a vendor pre-diligence review:

• Legal
  
• Commercial
  
• Financial
  
• Operational
  

“Good preparation isn’t showing the buyer everything — it’s anticipating what they’ll ask before they ask it,” says John.

Month 11 – Define Your Story

Buyers buy confidently when there’s a coherent narrative.

Prepare:

• Future growth plans
  
• Strategic opportunities
  
• Weakness mitigations
  

“Buyers don’t just buy numbers — they buy what those numbers predict about future performance,” says John.

Month 12 – Engage Expert Support

By now you should know:

• What’s working
  
• What’s risky
  
• What’s negotiable
  

That’s when you bring in a specialist broker to:

• Package the story
  
• Craft the information memorandum
  
• Reach targeted buyers
  

“Expert brokers don’t just list your business — they position it,” John emphasises. “That’s what separates a mediocre exit from a premium sale.”

Final Tip

This isn’t a checklist — it’s a value creation calendar.
If you start this plan early, you don’t just prepare a business for sale — you can engineer a better outcome.
