Selling & Exit
Pre-Sale Preparation Roadmap for UK SME Owners
The owners who get the strongest deals start 18 months out. Here is the month-by-month roadmap we use.
A clean, well-prepared sale process is the difference between an offer at the top of the range and a 12-month grind ending with a price chip. The owners who get the strongest deals start the work 18 months before they want to leave. This guide walks through the roadmap month by month: baseline valuation, value-gap fixes, information pack, adviser selection, and a disciplined buyer process that protects the trading position throughout.
Months 1-3: baseline valuation and value-gap diagnosis
UK SME pre-sale preparation runs over an 18-month horizon and covers four workstreams in sequence: earnings normalisation, structural risk remediation, management bench-building, and buyer-list construction. The purpose is not to fall in love with a number; it is to identify the gap between today's value and the value you want at exit. We map that gap to specific factors, customer concentration, recurring revenue, owner dependency, management depth, gross-margin trend, and a 12 to 18-month plan to close it.
This phase also includes a hygiene check on shareholder agreements, key contracts, IP ownership, employee equity, and historic tax positions. Issues found now are fixable. Issues found in due diligence cost money or kill deals.
Months 4-9: value-uplift execution
This is the period that decides whether the sale lands at 4x or 6x. Specific moves: hire a deputy MD with profile, sign two or three mid-size customer wins to dilute top-customer concentration, convert at least 30% of project revenue to retainer, lift gross margin by a couple of points through pricing and contract exits, and put monthly management accounts on a 10-working-day close.
We work alongside the management team and the existing finance lead to drive these in parallel. A weekly stand-up against the value-gap plan keeps focus. The goal is not perfection by month nine; it is visible, evidenced progress that supports the higher multiple at the negotiating table.
Months 10-12: information pack and adviser selection
The information pack is the document buyers will live with for 4 to 6 months. Built well, it answers the obvious questions and avoids the avoidable price chips. It includes three years of statutory accounts, three years of management accounts with KPI dashboards, customer mix, supplier mix, contract summary, employee structure, IP and IT inventory, premises position, and a 3-year forward plan with realistic assumptions.
Adviser selection happens in parallel. For deals below £3m enterprise value, a small specialist boutique is usually the right fit. £3m to £15m, a regional corporate finance house with sector reach. Above £15m, a national mid-market house. We help owners interview shortlists and structure the engagement letter so fees align with outcomes.
Months 13-15: buyer list and confidential outreach
The buyer list is short and curated. For most SMEs, 15 to 30 named buyers is the right scope: trade consolidators, PE platforms with sector remit, and one or two strategic buyers from adjacent sectors. Approaches go out under NDA, with a sanitised teaser that protects the trading position.
We protect confidentiality throughout. Staff, customers, and suppliers are not told. The trading position must not weaken during the process; a wobble at this stage is the most common reason buyers chip the price in months 16 to 18.
Months 16-18: offers, due diligence, completion
Initial offers (heads of terms) typically arrive 6 to 8 weeks after outreach. The best ones are evaluated on price, structure (cash up front versus deferred), warranty and indemnity exposure, earn-out terms, and cultural fit for the team. The headline price is rarely the right comparator.
Due diligence runs 8 to 12 weeks. The information pack does most of the heavy lifting; the buyer's accountants and lawyers fill the gaps. Sale and purchase agreement negotiation runs in parallel during the final 4 to 6 weeks. Completion is anti-climactic if the previous 18 months have been disciplined.
What goes wrong, and how to avoid it
Three failure modes recur. First, owner fatigue: by month 14 the founder is tired and accepts terms they would have rejected at month 1. The cure is an adviser who absorbs the process so the founder can keep trading. Second, trading wobble: a soft quarter mid-process invites a price chip. The cure is to keep eyes on the business, not the deal. Third, late surprises in due diligence: an unrecorded liability, a key employee threat, an IP gap. The cure is the early hygiene check in months 1 to 3.
Key takeaways
- Start 18 months out; the first 9 months drive the multiple.
- Value-uplift moves are concrete and measurable.
- Information pack quality controls due diligence outcomes.
- Headline price is rarely the right comparator; structure matters.
Frequently asked questions
How early should I start preparing for sale?
Eighteen months is the sweet spot for owner-managed businesses. Shorter periods limit the value-uplift moves you can make; longer periods risk losing momentum and energy.
Do I need an adviser, or can I sell directly?
Direct sales work occasionally with a single, well-known buyer. For competitive processes, an adviser typically adds 10 to 30% to the final price and absorbs 80% of the workload. For deals above £1m enterprise value, the fee almost always pays for itself.
How do I keep the sale confidential from staff?
Tight buyer lists under NDA, sanitised teasers, and disciplined process management. We have run hundreds of processes without staff or customers learning until the announcement at completion.
What if I do not have monthly management accounts?
Implementing them is one of the first value-uplift moves. Buyers and lenders both expect them. Without them, the buyer will impose a discount for opacity, often two turns on the multiple.
Should I tell my key customers I am selling?
Only at completion, and ideally jointly with the buyer. Telling customers earlier invites them to renegotiate terms or look at alternatives, and the price chip that follows is severe.
What deal structures should I expect?
Cash on completion is rare above £3m; expect 60 to 80% upfront with the balance deferred or as earn-out. Structure matters as much as headline price; we negotiate both.
