Buying a running business is one of the most efficient routes to acquiring an established operation with customers, revenue, and a functioning team. Compared with starting from scratch, acquiring an existing business provides a solid foundation on which to build — but it also involves specific risks that must be understood and managed.

This article analyses the advantages, risks, and process of buying a running business in the Spanish market, with a practical focus based on Blue Mountain Capital’s experience in over a decade of direct investment in the middle market.

Advantages of buying a running business

Immediate cash flow

The most tangible advantage of acquiring an operating company is that it generates revenue from the very first day of ownership. There is no “valley of death” that characterises new ventures, where months or years without revenue can exhaust the entrepreneur’s resources.

A running business has signed contracts, orders in progress, and a commercial structure producing revenue. This financial predictability significantly reduces buyer risk and facilitates securing financing for the acquisition.

Established customer base

Building a customer portfolio from scratch requires years of commercial effort. When buying a running business, you acquire established commercial relationships, market reputation, and competitive positioning built over years or decades.

What matters is not just the number of customers, but the quality of the relationships: tenure, recurrence, diversification, and satisfaction. A well-diversified customer base with high retention is one of the most valuable assets of any company.

Trained workforce

Talent is hard to find and harder to retain. A running business has a team that knows the business, the processes, and the customers. This accumulated knowledge has enormous value that does not appear on the balance sheet but is decisive for the success of the operation.

The key is to evaluate team quality during due diligence and design a retention plan that prevents talent flight after the acquisition. Massive turnover in the first months post-closing is one of the greatest destroyers of value.

Operational infrastructure

Premises, equipment, technology, processes, approved suppliers, licences, and permits — all of this already exists and works. Replicating this infrastructure from scratch would require significant investment and months of ramp-up.

Verifiable financial track record

Unlike a start-up, where everything is projection, a running business has a real financial track record. You can analyse financial statements from the past three to five years, identify trends, evaluate revenue quality, and calculate normalised EBITDA with real data.

Risks of buying a running business

Inherited contingencies

When you buy a company, you inherit its history — including any tax, employment, legal, and environmental contingencies it may have. An undisclosed lawsuit, a pending tax inspection, or an undocumented employment commitment can turn a good acquisition into an expensive lesson.

Due diligence is the primary mechanism for identifying these contingencies before closing. But no due diligence is perfect. Therefore, the purchase agreement must include seller representations and warranties, backed by an escrow mechanism that protects the buyer against contingencies that surface after closing.

Founder dependency

In many Spanish middle-market companies, especially family businesses, the founder is the central axis of the business: they know the key customers, make the critical decisions, and embody the company’s culture.

If founder dependency is high, the post-acquisition transition becomes the critical success factor. You will need a sufficient transition period (12-24 months), a plan for progressive delegation, and possibly the recruitment of an external general manager to assume the founder’s functions.

Hidden problems

Companies for sale present their best version. Real problems — latent labour conflicts, dissatisfied customers, technical debt in systems, informal processes that are not documented — are only discovered during due diligence or, worse, after closing.

Commercial due diligence (customer and supplier interviews) and operational due diligence (site visits, process analysis) are as important as financial and legal due diligence. Do not neglect them.

Resistance to change

The company you buy has an established culture, ways of doing things, and inherent resistance to change. A buyer who arrives with an aggressive transformation plan and implements it without sensitivity will find resistance, demotivation, and turnover.

The balance is to respect what works, change what must change, and do it at a pace the organisation can absorb.

Step-by-step acquisition process

The acquisition of a running business follows well-defined phases. For a complete and detailed guide to each step, see how to buy a company in Spain.

1. Define search criteria

Before searching, define what you are looking for: sector, size (revenue and EBITDA), geographic location, level of founder dependency, and growth potential. The more precise your criteria, the more efficient the process.

2. Identify opportunities

Use multiple channels: M&A advisors, intermediaries, professional networks, chambers of commerce, and sector contacts. The best opportunities are rarely found on public business-for-sale portals.

3. Preliminary analysis and valuation

Evaluate the available information (information memorandum), calculate an indicative valuation based on EBITDA multiples, and decide whether to proceed. Do not fall in love before having the numbers clear.

4. Letter of intent

If the analysis is positive, submit a letter of intent with the basic terms of the transaction: indicative price, structure, exclusivity, and timeline.

5. Due diligence

The most critical phase. Conduct exhaustive verification across all dimensions: financial, tax, legal, employment, commercial, and operational. Consult our buyer’s due diligence guide for a detailed treatment.

6. Negotiation and closing

Negotiate the purchase agreement, establish protection mechanisms (warranties, escrow, price adjustments), and close the deal.

7. Integration and value creation

Closing is not the end. It is the start of the value-creation phase that will determine whether the investment was sound.

Evaluation criteria for a running business

To evaluate a company as an investment opportunity, we recommend analysing five critical dimensions:

Revenue quality. Are revenues recurring or one-off? What is the customer concentration? What is the retention rate? Are margins sustainable?

Human capital. Is there a management team capable of operating without the founder? What is the average team tenure? Are there internal succession plans?

Competitive position. Does the company have defensible competitive advantages? What is its market share? Is the sector growing, mature, or declining?

Asset condition. Are assets (premises, machinery, technology) in good condition? Do they require significant short-term investment?

Improvement potential. Are there clear value-creation opportunities? Can margins be improved? Are there opportunities for geographic or product expansion?

Sectors with the most opportunities

In the current Spanish market, the sectors with the greatest buying and selling activity include logistics, industrial services, hospitality and catering, applied technology, food and agriculture, and family businesses undergoing generational succession.

Conclusion

Buying a running business is a sound strategy for accessing an established operation with cash flow, customers, and a team. But it requires rigour in analysis, discipline in valuation, and a clear plan for integration and value creation.
