Selling a Software or SaaS Business in the UK
Software and SaaS businesses attract some of the most active buyers in the current UK mid-market — and they're valued differently from almost every other type of business. If your software company generates reliable recurring revenue, the right buyer will pay a meaningful premium for that predictability. The key is understanding which valuation framework applies to your business, what buyers are actually looking for, and how to position yourself before you go to market.

How is a software business valued in the UK?
The honest answer is: it depends almost entirely on the nature of your revenue. A software business isn't a single asset class — and buyers know the difference between a genuinely recurring subscription model and a licence-plus-maintenance arrangement dressed up to look like one.
There are broadly two valuation frameworks in play:
Revenue multiples apply where the business has strong, demonstrable Annual Recurring Revenue (ARR) with a clear growth trajectory. Pure-play SaaS businesses — cloud-hosted, subscription-billed, low churn — can command between 1x and 5x ARR, with the upper end reserved for businesses growing ARR at 20–40%+ annually with gross margins above 70%. At this level, buyers are paying for future growth, not just today's earnings.
EBITDA multiples apply to more mature software businesses: established products with a stable customer base, lower growth rates, and solid profitability. These businesses are typically valued at 6x–12x EBITDA, sometimes higher where there's a defensible niche or deep customer dependency. Legacy on-premise software with declining renewal rates sits at the lower end of that range.
| Business Type | Valuation Basis | Typical Multiple Range |
|---|---|---|
| High-growth SaaS (ARR growth 20%+, gross margin 70%+) | Revenue (ARR) | 2x–5x ARR |
| Steady SaaS (ARR growth 5–20%, good retention) | Revenue or EBITDA hybrid | 1x–2x ARR or 8x–12x EBITDA |
| Mature software (lower growth, profitable, stable) | EBITDA | 6x–10x EBITDA |
| On-premise / legacy software (flat or declining) | EBITDA | 4x–7x EBITDA |
| Professional services-heavy software (low margin) | EBITDA | 4x–6x EBITDA |
Multiples as at 2026. Ranges reflect deal activity in the UK mid-market. Individual businesses will vary considerably.
What metrics do buyers focus on?
If you run a services business, buyers analyse your profits. If you run a software business, they analyse your metrics — and they will interrogate each one during due diligence.
Net Revenue Retention (NRR) is arguably the most important number. NRR measures what percentage of last year's recurring revenue you still have this year, after accounting for churn, downgrades, and expansions. An NRR above 100% means your existing customers are growing their spend — which is the definition of a healthy SaaS business. Buyers will pay a premium for this.
Gross margin should be 70% or above for a software business to attract software-style multiples. If your gross margin is depressed by high implementation costs, third-party hosting fees, or significant professional services revenue bundled in, buyers will apply a blended or services-style multiple instead.
Annual Contract Value (ACV) and Average Revenue Per User (ARPU) matter because they tell buyers how hard it is to replace a lost customer. High ACV with multi-year contracts is a positive signal. High customer count at low ACV with monthly billing is a risk factor unless churn is demonstrably low.
Customer Acquisition Cost (CAC) vs Lifetime Value (LTV) — buyers want to see an LTV:CAC ratio of at least 3:1. If it costs you £10,000 to acquire a customer who generates £12,000 over their lifetime, the economics don't support growth investment. Businesses with strong LTV:CAC ratios are far more attractive to PE-backed platforms looking to scale.
Churn rate — monthly churn above 2–3% is a red flag for most buyers. Annual logo churn above 10–15% will be heavily scrutinised. Be prepared to explain your churn drivers and what you've done about them.
Who buys UK software businesses?
The buyer universe for quality UK software businesses is broader than most owners expect — and it extends well beyond the UK.
PE-backed vertical market software platforms are currently the most active acquirers in this space. The buy-and-build model in vertical software — where a platform acquires a series of niche software businesses serving a specific sector — has been extremely active over the past five years and shows no sign of slowing. If your software serves a defined industry (construction, healthcare, logistics, facilities management, legal, accounting), there is likely a PE-backed platform actively looking for businesses like yours.
Trade acquirers — typically larger software companies seeking to extend their product suite, enter adjacent markets, or acquire your customer base — are another significant buyer type. These buyers often move faster than PE and may be willing to pay a strategic premium if your product fills a clear gap in their offering.
US and European buyers are frequently active in UK software M&A. US acquirers in particular are comfortable with revenue multiples that UK-only buyers may not reach, and cross-border deals in software are now relatively common at the mid-market level. Don't assume your buyer will be domestic.
Direct PE investment is also possible for software businesses generating £2m+ EBITDA with strong recurring revenue characteristics, particularly where a credible management team is in place post-sale.
What will buyers examine closely?
The diligence process for a software business goes well beyond standard financial review. Expect buyers to focus on the following:
Contract terms. Annual billing with auto-renewal and limited cancellation rights is significantly more attractive than monthly rolling contracts. If a large proportion of your ARR is on monthly contracts, buyers will apply a risk discount. Before going to market, consider whether you can move key customers to annual billing.
Technical architecture. Cloud-hosted software (AWS, Azure, GCP) is valued more highly than on-premise installations. Legacy on-premise software carries additional risks — upgrade cycles, data security, customer resistance to migration — which buyers will price in. If your product is in transition from on-premise to cloud, document the roadmap and traction carefully.
Key person dependency. If you are the original developer and you hold the technical knowledge, buyers face a genuine continuity risk. This is one of the most common value suppressors in owner-managed software businesses. Being able to demonstrate a capable development team, documented codebase, and clear technical handover process will materially improve your valuation.
Customer concentration. If your top three customers represent more than 40–50% of ARR, buyers will apply a concentration discount. Similarly, government or public sector contracts need careful review — they can be re-tendered or terminated in ways that private sector contracts cannot.
Competitive positioning. Buyers want to understand why customers choose you and stay with you. A defensible niche, switching costs embedded in the product, or deep integration into a customer's operations are all positive signals. Vague claims about "best in class" functionality are not.
What does the sale process look like?
A well-run software business sale typically follows this sequence:
- Preparation (2–4 months) — Compile your SaaS metrics, tidy up your contracts, document your technical architecture, and prepare management accounts that clearly separate recurring from non-recurring revenue.
- Information Memorandum — A detailed document covering your product, market, metrics, team, and financials. Software buyers want metrics front and centre.
- Buyer outreach — Targeting both domestic and international buyers across PE platforms, trade acquirers, and direct PE. A structured process creates competitive tension that supports valuation.
- Indicative offers (Heads of Terms) — Usually 4–8 weeks into the process. Expect buyers to probe metrics hard before confirming indicative figures.
- Exclusivity and due diligence — Technical, commercial, legal, and financial due diligence runs simultaneously. Budget 8–12 weeks.
- SPA negotiation and completion — Warranties and indemnities around IP ownership, customer contracts, and data protection (UK GDPR) are typically significant in software transactions.
Total timeline from preparation to completion: 9–15 months for a mid-market software business.

FAQ
Do I need audited accounts to sell a software business in the UK? Not necessarily, but management accounts presented clearly — with recurring and non-recurring revenue separated, and standard SaaS metrics tracked — are essential. Buyers will want at least three years of financial history and monthly MRR/ARR data.
Can I sell my software business if I'm the only developer? Yes, but key person dependency will affect your valuation and deal structure. Buyers may insist on a longer earn-out, retention period, or require you to document the codebase and bring in a technical lead before or during the sale process.
What is a typical earn-out structure for a software business sale? Earn-outs in software deals are common where there's uncertainty around growth projections. A typical structure might be 70–80% upfront with 20–30% deferred over one to two years, tied to ARR or EBITDA targets. The specifics vary significantly depending on buyer type and deal size.
Does Business Asset Disposal Relief (BADR) apply to software business sales? BADR can apply to qualifying disposals of trading companies, potentially reducing Capital Gains Tax to 14% (2025–26 rate) on gains up to £1 million lifetime limit. However, the rules around trading status, qualifying shareholdings, and the definition of investment activities are detailed. This article contains general information only and does not constitute financial or tax advice. Every business sale is different. Speak to a qualified UK tax adviser about your specific situation before making any decisions.
Will US buyers pay more for a UK software business? Often, yes — US buyers are accustomed to revenue multiples and may apply a higher valuation than UK-based buyers relying on EBITDA frameworks. However, currency risk, cross-border legal complexity, and warranty expectations can complicate these deals. International buyers are absolutely worth approaching through a structured process.
How long does it take to sell a software business in the UK? From preparation to completion, expect 9–15 months for a mid-market deal. Complex technical due diligence, SPA negotiation around IP and data protection, and managing multiple international buyers all add time. A well-prepared business with clean metrics and documented contracts will move through this process faster.
