Custom choices

Which choices determine the content?

The form of your PoC or pilot agreement depends on a number of key choices. Answer the questions below before having the document drafted.

Choice or question Why this matters legally
Is the pilot free or paid? This determines the agreements regarding fees, invoicing, and what the parties may expect from each other.
Who becomes the owner of the results? Customization or development during the pilot requires clear agreements regarding intellectual property and usage rights.
Are personal data being processed? If so, additional GDPR arrangements or a data processing agreement are required.
Is progression to a permanent contract the intention? Determine whether the pilot is non-binding or whether an intention or option to continue is recorded.
Which party bears the risk in the event of damage? Document liability and any exclusions, precisely because a pilot is not yet fully developed.
Clauses and provisions

Which components belong in a proof of concept agreement / pilot agreement?

A comprehensive Proof of Concept (PoC) or pilot agreement describes the purpose of the test, the duration, and the mutual obligations. The components below belong in virtually every agreement; you can supplement them further depending on your situation.

Provision Relevant to Legal point of attention
Goal and scope Always Describe what is being tested and what concrete result the pilot must demonstrate.
Success criteria Always Measurably define when the proof of concept is considered successful, to prevent subsequent discussion.
Duration and phasing Always Determine the start and end dates and any interim evaluation points.
Costs and fees Always Determine whether the pilot is free of charge or at what (reduced) rate, and who bears which costs.
Intellectual property During development Determine to whom the results, data, and any developed software accrue.
Confidentiality With sensitive information Requires parties to keep confidential data and test results secret.
Data processing Regarding personal data Make agreements that comply with the GDPR if personal data is processed during the pilot.
Continuation and exit Always Specify what happens after the pilot: non-binding termination, cancellation, or progression to a permanent contract.
Use in practice

How do you use this document correctly?

A Proof of Concept or pilot agreement only works if you deploy and comply with it at the right times. Follow the steps below.

Situation What should you do? Point of attention
Before the start Sign the agreement before the pilot starts Without a prior signature, unclear obligations and disputes regarding agreements arise.
During the pilot Record results and deviations in writing This allows you to objectively assess whether the success criteria are met.
At the end Evaluate based on the agreed criteria This allows you to make a well-founded decision on whether to continue, stop, or adjust course.
To be continued Document the final collaboration separately A pilot agreement is not intended as a long-term contract and must be replaced.
Common mistakes

Common mistakes

With proof-of-concept and pilot agreements, things often go wrong on the same points. The errors below are seen most frequently, along with the consequences and how to prevent them.

Wrong Consequence Better approach
No measurable success criteria Post-pilot discussion on whether the pilot was successful Establish concrete, measurable criteria in advance.
No end date The pilot continues unnoticed and becomes a permanent obligation Agree on a clear duration and evaluation point.
IP rights not regulated Uncertainty about who may use the results and data Determine in advance to whom the results belong.
GDPR overlooked Risk of fines and complaints when processing personal data Make appropriate GDPR arrangements or enter into a data processing agreement.
Confusing a pilot project with a definitive contract Unintended long-term binding on incorrect terms Conclude a separate contract for the definitive collaboration.
Risk profile

What is your situation and what do you pay attention to?

The key considerations for a Proof of Concept (PoC) or pilot agreement vary depending on the situation. If you recognize your situation below, you know what to pay extra attention to.

Risk profile Example Focus in the document
Software pilot You are temporarily testing software from a supplier Pay attention to usage rights, data portability, and ownership of configurations.
Joint development You are developing a concept together with a partner Handle intellectual property and confidentiality carefully.
Pilot with customer data Personal data is processed during the test Ensure a GDPR legal basis and appropriate processing arrangements.
Free trial period You offer or receive a free test Prevent the free pilot from silently turning into a paid obligation.
Additional documents

When is this document not enough?

A proof of concept or pilot agreement covers the testing phase. For other situations, you require additional or different documents.

Situation Supplementary document Why
The collaboration becomes permanent Cooperation Agreement For a structural collaboration after the pilot, you record the agreements in a full-fledged contract.
Personal data is being processed Data Processing Agreement A data processing agreement is mandatory when personal data is processed by a party.
You only want to ensure confidentiality Confidentiality Agreement If you only wish to arrange confidentiality before testing, an NDA will suffice.
Explanation of this document

Drafting a proof of concept agreement / pilot agreement, why?

Not every entrepreneur knows exactly what a proof of concept agreement / pilot agreement is, when you need them, and which risks they must cover. Therefore, we explain below what this document entails, what you should look out for, and why customized legal solutions are important.

What is a proof of concept agreement or pilot agreement?
A proof of concept (PoC) agreement or pilot agreement is the agreement in which a supplier and a potential customer agree to test a limited, temporary implementation of a product or service to assess whether the product meets expectations before a full-fledged commercial agreement is concluded. The PoC agreement regulates the scope of the test, the duration, the payment arrangement — paid or free PoC — the intellectual property rights to the data and results produced during the PoC, confidentiality, and the conditions under which the PoC transitions into a full-fledged agreement. In the software and IT sector, the PoC agreement has become standard in the sales process for higher-value solutions. Our lawyers draft PoC agreements for suppliers and customers that watertight define the test scope, correctly assign IP rights to test results, clearly formulate the transition condition to a full-fledged agreement, and safeguard the confidentiality of commercially sensitive information.
How do you prevent a free PoC from leading to an unwanted legal binding?
One of the most common pitfalls in PoC agreements is the situation where the customer continues to use the solution after the PoC period without signing a formal commercial agreement — and later claims to have accrued rights based on continued use. Your PoC agreement must explicitly state that access to the solution automatically terminates on the PoC end date, unless the parties expressly agree in writing to an extension or a commercial agreement. Continued use after the PoC period without a new agreement grants the customer no rights and does not bind the supplier to the PoC conditions. Our lawyers draft an automatic termination clause that protects the supplier in the event of tacit continued use.
How do you manage the intellectual property rights on test results and feedback?
During a Proof of Concept (PoC) or pilot, the customer generates test data, reports, and feedback containing valuable insights for the supplier's further product development. The question of who owns the intellectual property rights to these test results and feedback is a frequent source of discussion. The supplier wants to be able to use the feedback for product development without being restricted by the customer's IP claims. The customer does not want their commercially sensitive test results to be used for the development of products that are also sold to their competitors. Your PoC agreement must explicitly define the IP position on test results: the supplier may use anonymized and aggregated feedback for product development; specific commercially sensitive data and outcomes are confidential and may not be shared. Our lawyers draft an IP and confidentiality clause that protects both parties.
How does it work at MKBjuristen?
After a brief intake regarding the solution, the test scope, and the expectations, our lawyers draft a Proof of Concept (PoC) agreement or pilot agreement that watertightly defines the test scope, arranges for automatic termination, correctly assigns the IP rights to test results, and clearly formulates the transition conditions to a full-fledged agreement.
Are you unsure whether your document is legally correct? We would be happy to assess the sensible course of action: drafting, reviewing, or amending.

Why not use a standard document?

A standard document often seems like a quick solution, but usually does not fully align with your company, agreements, risks, and way of working. Our legal experts draft documents that fit your situation.

Standard document
SME Lawyers
Not tailored to your business
Tailored to your company, industry, and working methods
No control over your specific situation
Consultation with a lawyer and assessment of your risks
Possibly outdated or incomplete
Verification of current and practical provisions
No personal explanation
Explanation regarding the use of the document

A standard document seems cheap, until it doesn't fit your situation properly. That is why we provide custom legal solutions tailored to your business.

Custom solutions per industry and company

Every business operates differently and faces different legal risks. Therefore, we tailor the document to your industry, customers, agreements, and way of working.

Webshops & e-commerce

Focus on online sales, delivery, returns, complaints, payment, digital products, and consumer regulations.

Business services

Attention to the assignment, additional work, liability, payment, termination, and reliance on client information.

Construction, installation & execution

Attention to planning, delivery, warranties, additional work, materials, delays, and liability risks.

Software, SaaS & digital services

Attention to licenses, availability, support, updates, data, intellectual property, and limitation of liability.

Trade, supply & wholesale

Attention to delivery, transport, payment, retention of title, warranties, delivery times, and international agreements.

Consultants, freelancers & advisors

Attention to scope, best efforts obligations, cancellation, payment, liability, and confidential information.


A legal document only has value if it suits your practice. That is why we look not only at the text, but also at how you use the document in your business.

Common mistakes with legal documents

A legal document often seems simple, but small errors can have major consequences later on. In practice, we see that entrepreneurs run the greatest risk when a document does not align well with their business, agreements, or way of working.

  • Using a standard document that does not suit the company
  • Forgot important agreements regarding payment, delivery, liability, or termination
  • Have a document generated without legal review
  • Continuing to use old documents while the company has changed
  • Not knowing how the document should be used correctly in practice

A legal document only prevents problems if it suits your situation. That is why we look not only at the text, but also at your company, agreements, and risks.

Why is a standard document often not enough?

Because a standard document does not take into account your industry, customers, risks, and specific agreements, important provisions may be missing or not align well with your practice.

Can I create a legal document myself using AI?

AI can assist in creating text, but does not independently assess whether the document is legally appropriate, complete, and usable for your business. Legal review therefore remains important.

When do I need to have my document checked?

Have your document checked if your business has changed, you have new customers or services, you have doubts about existing agreements, or the document has not been updated for a long time.

Will I also receive an explanation about the use of the document?

Yes. We explain how to use the document in practice, what to look out for, and which steps are important to prevent disputes afterwards.
