When selling a business, the buyer pays not only for tangible assets and contracts but above all for goodwill: brand, customer base, reputation and the trust the previous owner has built up. It is precisely this trust that the seller can take back immediately after completion by starting again in the same industry and taking the old customers along. The non-compete with additional customer-protection and non-solicitation clauses protects against this.

This post explains how a non-compete on a business sale in Austria is drafted in a practicable way. The focus is on the substantive, geographic and temporal scope, customer protection, non-solicitation, the contractual penalty and the interplay with an earn-out, advisory contract and the seller acting as managing director.

From a lawyer perspective the clause is a tool, not an end in itself. It works only where it is tailored to the protection interest and does not devalue itself through excessive breadth. How it fits into the wider contract is closely linked to the warranty catalogue. The post on the SPA warranty catalogue offers the depth on that.

Classify your protection need

Does the non-compete in your transaction hold up?

Answer one or two questions on the seller follow-on activity and the reach of the clause. You receive an initial classification of the most important points to check.

Already know you want to get in touch? Go straight to the enquiry form.

01 Question 1

Will the seller remain active in the same industry after completion or hold personal customer relationships?

A non-compete makes sense above all where the seller could jeopardise the goodwill that has been sold through its own follow-on activity. A pure financial investor without operational ties is a different situation.

All paths at a glance

Overview of all answers.

01

Where the seller withdraws fully, the need has to be assessed soberly.

Anyone selling the company and withdrawing from the industry as a rule does not jeopardise the acquired goodwill through their own follow-on activity. A strict non-compete is then mostly not necessary. A non-solicitation for key employees and a confidentiality protection for internal information remain sensible. Further depth is offered by our focus page on business succession and transfer.

A short legal review clarifies whether the confidentiality and non-solicitation clauses already cover the remaining protection need.

02

The clause is robust, now its interplay with the rest of the contract matters.

If scope, customer protection and contractual penalty are clearly governed, goodwill is well secured. Make sure that the clause is aligned with the warranties, the earn-out and the purchase price. Whoever agrees an earn-out should at least extend the non-compete over the whole earn-out period. How an earn-out is built up is shown in the post on the earn-out purchase price clause.

A final review ensures that the clause protects the acquired goodwill without devaluing itself through excessive breadth.

03

Unclear or overstretched clauses jeopardise the effectiveness.

A temporally or geographically unlimited non-compete can be wholly or partly ineffective under Austrian law. A measured clause is sensible: substantively limited to the acquired business fields, geographically to the actual area of activity, temporally as a rule to two to three years. In addition the clause should contain a customer protection, a non-solicitation and a quantified contractual penalty.

Have the clause sharpened before signing. A sharply drafted, enforceable prohibition protects goodwill better than an apparently broad ban that does not hold up in dispute.

Goodwill as the protected interest and function of the clause

With the company the acquirer buys the economic sources of its future value creation. Alongside fixed assets and contracts this includes above all customer relationships, market reputation and the knowledge of the workforce. These intangible values are particularly fragile without active protection, because they often depend on individuals, above all the previous owner and the key employees.

The non-compete therefore secures what is most directly at risk: the option of the seller to approach the same customer base again immediately. By undertaking towards the buyer not to engage in competition in a defined substantive and geographic area for a certain period, the seller gives the buyer the time to consolidate the acquired relationships.

Customer protection and non-solicitation add to the picture. The customer protection prohibits the targeted approach of existing or recently lost customers, the non-solicitation protects against the loss of key employees. Both also operate where the actual non-compete does not bite, for example because the seller moves into another region or an adjacent industry. We explain the concept of the non-compete in the glossary.

Substantive, geographic and temporal scope

An effective clause must limit the protection to what is necessary for the protection of the acquired goodwill. Substantively the acquired business field belongs in the prohibition: the activities actually carried out and the products or services that the business offers in the market. An extension to neighbouring fields is possible where the buyer is already actively present there or has credibly prepared an expansion.

Geographically the clause orients itself to the actual market area of the company. For a regionally anchored operation a narrowly defined area often suffices, for businesses operating regionally or internationally a wider reach is conceivable. A blanket extension to the entire EU area should be underpinned by actual market presence, otherwise it goes nowhere.

Temporally a period of two to three years from completion is frequently agreed. A significantly longer period needs justification and can be wholly or partly ineffective under Austrian law. If a longer protection cannot be plausibly justified, the measured period is the better one because it actually holds. How completion conditions influence the start of the period is explained in the post on closing conditions.

Contractual penalty, injunctive relief and evidence

A non-compete clause only has practical value if a breach quickly becomes tangible. A quantified contractual penalty per individual breach is therefore usual. It relieves the buyer of having to quantify every single loss in concrete terms and makes the economic pressure visible immediately in dispute. An additional claim for further damage remains possible where it can be shown.

In addition the contract should expressly provide for the injunctive remedy and for interim relief. A clear contractual promise makes it easier in urgent cases to obtain an interim order against the seller ongoing activity. Whoever has to run only the main proceedings without these tools often loses the decisive months in which the customer base is just reorganising itself.

For the evidence cleanly documented handovers from the preparation phase help. Anyone who records customer lists, sales territories and key contacts at completion can later more easily prove targeted approaches by the seller.

Building blocks of a robust clause

What matters in the non-compete

These building blocks decide on enforceability and effect of the clause. Check each one before you sign.

Building blocks of the clause with recommended drafting and possible risk
Building block Recommended Possible risk
Substantive scope On the acquired business field Clearly described activities and products Sweeping bar on whole industries
Geographic scope On the actual market area Region or country where the business is actively present Extension to areas without market presence
Temporal scope Two to three years from completion Period covering the build-up of own customer ties Multi-year or open-ended bar
Customer protection Active approach prohibited Protection against targeted soliciting of existing customers Clause without reference to a concrete customer group
Contractual penalty Quantified per individual breach Quick economic pressure in dispute Flat-rate and hard to enforce

The benchmarks are usual reference points, not fixed requirements. Scope and duration are negotiated case by case and should fit the importance of the goodwill.

Caution with overstretched clauses: Whoever agrees a temporally or geographically boundless non-compete risks its full or partial ineffectiveness. A reduction maintaining validity is not a matter of course and leads to uncertainty in dispute. Have the clause sharpened before signing. Booking an initial consultation (72 euro) can quickly bring clarity.

Interplay with earn-out, advisory contract and managing director role

If the seller remains as adviser or managing director of the business, the situation changes. During that time corporate or contractual duties of loyalty towards the company already apply, an additional non-compete works above all for the time afterwards. It is therefore sensible to link the non-compete expressly to the end of the advisory role and tie it back to completion.

On an earn-out an additional consideration applies: where part of the purchase price depends on future earnings, the seller has an interest in the business of the company. A parallel competing activity would undercut that interest. It is therefore usual to provide the non-compete at least for the entire earn-out period, often with an appropriate follow-on period as well.

Finally the clause has to be aligned with the warranty catalogue. A warranty on continuing customer relationships only works if the seller does not destroy those relationships through its own follow-on activity. How the catalogue is built is shown in the post on the warranty catalogue.

Frequent questions

Non-compete and customer protection after a business sale.

How long may a non-compete after a business sale apply in Austria? +

There is no blanket statutory maximum duration. In practice two to three years from completion are usual and as a rule appropriate, because they give the buyer time to consolidate the acquired customer relationships. Longer periods are possible but must be justified by special circumstances. An overstretched clause can be wholly or partly ineffective.

What is the difference between a non-compete and a customer-protection clause? +

The non-compete prohibits the seller for a certain time from competing activity in general. The customer-protection clause prohibits only the targeted approach of certain customers of the business but allows a competing activity as such. In practice both clauses are often combined, because they address different risks and complement each other well.

How is a breach of the non-compete enforced? +

A quantified contractual penalty per individual breach is usual. It creates quick economic pressure and relieves the buyer of having to quantify every single loss in concrete terms. In addition the buyer can sue for injunctive relief and in urgent cases obtain an interim order against the ongoing activity. Further damages remain possible to the extent they can be shown.
