Selling a technology business is one of the most significant decisions a founder or owner will make, and the process differs from selling a traditional company in several important ways. Tech valuations often hinge on metrics that buyers in other sectors barely consider. Due diligence focuses on areas like intellectual property ownership and data protection compliance rather than physical assets. And deal structures frequently include earn-outs that carry tax consequences many founders only discover too late.
At Wilson Partners, our corporate finance team works with tech founders from early-stage growth through to exit. This guide sets out what you need to know about selling a tech business in the UK, covering valuation, tax planning, due diligence preparation and the types of buyer you are likely to encounter.
Understanding what drives the value of a tech business
The value of a business is not determined by a simple formula. Instead, it hinges on numerous factors, including earnings, growth prospects, industry conditions and the context of the valuation. For tech companies, this is particularly true because the weighting of those factors shifts compared to other sectors.
In a traditional business, buyers and investors look closely at metrics like EBITDA, which represents earnings before interest, tax, depreciation and amortisation, as a gauge of operating profitability. Higher maintainable earnings generally translate to higher value. That principle still applies in tech, but it is often supplemented by revenue-based metrics that reflect the recurring and scalable nature of the business model.
SaaS and subscription metrics that buyers focus on
If your tech business operates a subscription or SaaS model, buyers will scrutinise a specific set of performance indicators alongside the standard financial metrics.
Annual recurring revenue, commonly referred to as ARR, is the starting point. This is the annualised value of your contracted recurring software revenue, and it needs to be clean. Buyers will want to see ARR reconciled against your bank statements and billing data, with one-off implementation fees or services revenue separated out. Mixing revenue streams inflates the number and will be challenged during due diligence.
Net revenue retention measures how much revenue you keep and grow from your existing customer base, accounting for churn, downgrades and upsells. A figure above 100% signals that your existing customers are spending more over time without you needing to acquire new ones. This metric can move your valuation multiple more than many founders expect.
The Rule of 40 is widely used by buyers and investors to assess the balance between growth and profitability. It states that your revenue growth rate plus your profit margin should exceed 40%. A company growing at 30% per year with a 15% margin scores 45 and sits in healthy territory. A company growing at 30% with a negative 10% margin scores 20 and will face questions about its path to profitability.
Customer concentration also matters. A strong, predictable cash flow increases value, and businesses with a well-diversified customer base, loyal customers and long-term contracts tend to attract higher multiples. On the other side, if your revenue is overly concentrated in a few customers, buyers may discount the valuation to reflect the risk of losing a material account post-completion.
Why management independence affects your multiple
A strong, experienced management team that can operate the business without heavy owner dependence will drive value up. Buyers pay more for companies that are not solely reliant on the founder or a few key people. If you have good second-tier management and clear processes, the business is more sustainable.
This is especially relevant in tech where the founder often serves as chief architect, lead salesperson and product visionary rolled into one. If the business cannot function without you, a keyman discount is applied, which impacts the value negatively. Building out your leadership team well before going to market is one of the highest-return activities a tech founder can undertake.
Valuation methods for tech businesses
Valuing a tech business involves selecting the right approach for the situation. According to international valuation standards, there are three accepted valuation approaches: the market approach, the income approach and the cost approach. In practice, professional valuers will typically use a primary method and cross-check it with one or two others to ensure the valuation is reasonable.
Market approach
This approach bases your business’s value on market prices of comparable companies or transactions. For tech businesses, comparable transactions in the sector set benchmarks for value. If similar SaaS companies with your growth profile and retention metrics have sold at a particular ARR multiple, that provides a reference point, adjusted for the specifics of your business.
It is important to keep in mind that a professional valuer will apply various discounts and premia to account for the benefit of control, company-specific risks and lack of marketability, all of which are unique to your business.
Income approach
The income approach values the business based on its ability to generate cash or profit in the future. The most widely used method is the discounted cash flow, which calculates the present value of projected future cash flows. Future cash flows and a terminal value are estimated and then discounted back at a rate that reflects the risk.
For high-growth tech companies with significant forward projections or large pipeline contracts, a DCF can capture value that a simple earnings multiple might miss. However, the assumptions underpinning the projections will be heavily scrutinised, so they need to be defensible.
Cost approach
This approach looks at the net asset value of the business. For most tech companies, the cost approach sets a floor rather than a ceiling. Profitable tech companies typically trade well above their asset value due to intangible goodwill in the form of software IP, customer relationships and brand. However, for asset-intensive or pre-revenue businesses, it may be the most appropriate starting point.
Tax planning before you sell
Engaging a tax adviser as part of your exit planning is crucial. The UK offers reliefs that can significantly reduce the tax on a business sale, but they require careful preparation and need to be in place well before completion.
Business Asset Disposal Relief
Business Asset Disposal Relief, formerly known as Entrepreneurs’ Relief, allows qualifying business owners to pay a reduced rate of capital gains tax on qualifying gains up to a lifetime limit of £1 million. The rate is currently 14% for disposals made from 6 April 2025, and this will rise to 18% from 6 April 2026. By comparison, the standard CGT rate for higher-rate taxpayers is 24%, so the relief remains valuable even after the increase.
To qualify, you must have owned at least 5% of the company’s shares and voting rights and been an employee or director for a continuous period of at least two years before the disposal. The company must be a trading company throughout that period.

The earn-out trap
Earn-outs are extremely common in tech transactions. A buyer will pay a proportion of the price upfront, with additional payments contingent on the business hitting specified performance targets over one to three years after completion.
The tax issue is that the right to receive earn-out payments does not qualify for BADR. The gain on the upfront cash element may qualify for the reduced rate, but any gain arising on the earn-out element is taxed at the standard CGT rate of up to 24%. Many tech founders are caught off guard by this distinction, and it can materially change the after-tax proceeds of the deal.
Structuring considerations around earn-outs, deferred consideration and loan notes should be discussed with your tax adviser and corporate finance team early in the process. The earlier you model these scenarios, the better position you are in to negotiate terms that work.
EMI share options before completion
If your company operates an Enterprise Management Incentive scheme, the interaction between EMI options and a sale needs careful handling. Options typically need to be exercised before or at completion, and if qualifying conditions have not been met continuously, there may be unexpected income tax charges rather than the capital gains treatment your team is expecting. This should be reviewed as part of your pre-sale preparation, not left until the deal is in progress.
Preparing for tech-specific due diligence
Buyers will perform thorough due diligence, and for tech businesses, the scope extends well beyond the standard financial and legal review. Cleaning up your records and resolving any discrepancies up front will add tremendous value to the process and reduce the risk of last-minute price adjustments.
Intellectual property ownership
IP is the core asset in most tech transactions. Buyers will want to confirm that all intellectual property created by employees and contractors has been properly assigned to the company. Without signed IP assignment agreements, the rights may legally remain with the individual who created the work, even if they were paid to produce it. This is a common issue with contractors hired from freelancer platforms or third-party development agencies.
Source code documentation is also scrutinised. Well-documented, annotated and tested code is expected in any tech transaction of meaningful size. Gaps here can be a deal-breaking issue and are avoidable through adequate preparation.
Open-source licence compliance
If your product incorporates open-source components, buyers will review the licence obligations attached to each one. Certain open-source licences carry copyleft provisions that could require you to release your own source code under the same terms. A bill of materials for all open-source dependencies, along with confirmation that licence obligations are being met, should be prepared ahead of due diligence.
Data protection and GDPR
For any tech business processing personal data, GDPR compliance is a core due diligence area. Buyers will review your data processing agreements, privacy notices, data retention policies and evidence of compliance with data subject access requests. Weaknesses here can delay completion or result in specific indemnities being required in the sale and purchase agreement.
Deal structures and buyer types
The routes to selling a tech business range from trade sales and private equity transactions to management buyouts. Each buyer type comes with different priorities, valuation approaches and deal structures.
Trade buyers
A competitor, complementary business or larger corporate acquiring your company for strategic reasons, trade buyers often pay the highest headline prices because they can realise synergies, whether through cross-selling to their existing customer base, acquiring your technology to fill a product gap, or eliminating a competitor. However, they will typically want to integrate the business, which may mean changes to your team and operations post-sale.
Private equity
Private equity firms back management teams by injecting equity for a share of ownership. PE investors often enable larger transactions and bring operational expertise, but they will expect a significant return, usually via a future exit within three to five years. PE buy-and-build strategies are common in tech, where a platform acquisition is followed by bolt-on purchases to build scale. If your business is the right size and profile, PE can be an attractive route that allows you to take some money off the table while retaining a stake in the upside.
Management buyout
A management buyout is a route where your existing management team becomes the new owner. An MBO can be an attractive option for founders looking to reward loyal team members and ensure business continuity. MBOs are quite common in the UK SME market but they require careful planning and often creative financing.
The buyout is usually funded by a combination of bank loans, private equity investment, vendor financing and the management team’s personal funds. In many MBOs, the seller agrees to finance part of the purchase price through deferred payments or a loan, which aligns interests and gives the team breathing room on upfront payment.
Agreeing on the valuation in an MBO is a delicate matter because the buyers and the seller have to find common ground. An independent valuation can help set a fair price range. It is critical that the business is not burdened with so much buyout debt that it struggles afterward.

Enterprise value versus equity value
A critical technical point when discussing deal values. Valuation multiples typically refer to enterprise value, which is the value of the entire business operations. This must then be adjusted for debt and cash to arrive at the equity value, which is the actual price you receive for your shares.
A tech business valued at 6x ARR on an enterprise value basis does not mean you pocket that full amount. Outstanding debt, including any venture debt or loan notes, is deducted. Surplus cash above normal working capital requirements is added. The adjustment from enterprise value to equity value is where many founders are surprised, so ensure you understand the bridge between the two figures early in the process.
Getting your business ready to sell
Exit planning is all about preparing your business for a future sale so that when the time comes, you achieve the best possible outcome. It is wise to start exit planning well in advance because maximising business value and ensuring a smooth sale takes time.
The key areas to address include growing recurring revenues and reducing customer concentration, ensuring your financial statements and management accounts are up to date and accurate, resolving any outstanding legal or compliance issues, building a management team that can operate independently, and assembling the right advisory team of corporate finance advisers, lawyers and tax specialists.
Getting your financials and records in order is particularly important. Buyers will perform thorough due diligence, and cleaning up financial statements, ensuring you have up-to-date management accounts and resolving any discrepancies up front will add tremendous value.
Your next steps
If you are considering selling your tech business, the preparation work should begin well before you go to market. A realistic valuation from experts is required because it underpins major decisions and negotiations, and a professional valuation provides credibility when entering early-stage negotiations with potential buyers.
