Building a Business You Can Sell: What Buyers Look for in SMB Valuations

Why most SMBs are worth less than their owners expect#

UK business brokers consistently report the same scenario: an owner expects to sell their £600K revenue business for £1.5M and receives offers of £400,000-£600,000. The gap is not about the revenue — it's about the business's value independent of the owner. When a buyer's due diligence team walks through the business, they're asking: 'If this owner leaves on day one of completion, does the business continue to perform?' In most SMBs, the honest answer is no. Customer relationships are personal to the founder. The product quality depends on the founder's oversight. Key supplier terms exist because of the founder's long-standing relationship. The financial records are basic — enough to file tax returns but not sufficient for investor-grade analysis. These factors systematically reduce the valuation. A business that could generate £120,000 EBITDA is worth £480,000-£600,000 at 4-5x if it runs independently. If it's founder-dependent, buyers apply a 30-50% discount — bringing the offer down to £240,000-£360,000.

The four valuation drivers that buyers pay premiums for#

Buyers in the SMB market — whether trade buyers, private equity, or management buyout teams — consistently pay premium multiples for four characteristics: (1) Recurring revenue — businesses with subscription income, standing orders, or highly predictable repeat purchasing command higher multiples because the revenue is more certain. A business where 60%+ of revenue is from customers who've bought for 3+ consecutive years is worth more than the same revenue from one-off transactions. (2) Documented systems — businesses with written SOPs, documented processes, and a trained management team demonstrate that the business runs without the owner. Every undocumented process is a buyer risk. (3) Clean, audited financials — monthly management accounts, audited annual accounts, and clean separation of business and personal expenses. (4) Customer diversification — no single customer representing more than 15% of revenue (see our guide on customer concentration risk).

EBITDA multiples: What different types of SMBs actually achieve#

UK SMB transaction data from 2022-2024 shows the following EBITDA multiple ranges by sector and quality: retail (1-2 locations, founder-dependent): 2-3x; retail (3+ locations, management team in place): 4-6x; hospitality (single-site, owner-operated): 2-3x; hospitality (multi-site, consistent unit economics): 4-7x; professional services (dependent on founder relationships): 2-4x; professional services (institutional client relationships, recurring revenue): 4-8x; manufacturing/production (asset-heavy, fragmented customer base): 2-3x; manufacturing (proprietary product, recurring customers): 4-7x. The difference between 3x and 6x on £120,000 EBITDA is £360,000 vs £720,000 — a difference of £360,000 in your personal exit outcome. These are not marginal improvements from different marketing tactics. They come from the structural factors described above: systems, management, recurring revenue, and financial transparency.

The 3-year preparation timeline#

A business sold with 3 years of preparation consistently outperforms one sold reactively (due to owner burnout, health event, or opportunity) by 40-70% on exit valuation. The 3-year timeline: Year 1 — Get your financials right. Engage a good accountant, produce monthly management accounts, separate all personal expenses from the business, and start building your EBITDA track record. Year 2 — Build the management team and document your systems. The goal is a business that can trade for 6 months without you in an operational role. Year 3 — Optimise for the sale. Improve any valuation detractors (customer concentration, supplier dependency, revenue seasonality), engage a business sale advisor for a pre-sale valuation review, and prepare your data room (the documents a buyer will request in due diligence).

The data room: What buyers ask for#

When a buyer's team begins due diligence, they'll request a data room containing: 3 years of filed accounts and management accounts, monthly P&L and cash flow statements for the last 24 months, customer list with revenue by customer and tenure (proving diversification and loyalty), employee contracts and structure chart, supplier contracts and terms, property leases and remaining term, and management accounts for the current trading year versus budget. The businesses that sail through due diligence have most of these documents ready to go — because they've been running the business with investor-grade financial transparency. The businesses that struggle have incomplete records, mixed personal and business expenses, and informal arrangements with key customers and suppliers that aren't documented. A 3-month due diligence process that uncovers surprises typically results in a 10-20% price reduction post-offer.
