Do I Really Need a Data Processing Agreement (DPA)? 

A larger customer is ready to move forward. Then their legal team sends you a Data Processing Agreement. 

Do you actually need one, and what are you agreeing to if you sign it? 

For founders, a Data Processing Agreement (DPA) can look like another document standing between the company and a signed deal. But it may contain commitments about security, vendors, data deletion, international transfers, and incident response that your company will actually have to perform. 

The goal should not be to get the DPA signed as quickly as possible. It should be to make sure the contract reflects how your company handles customer data. 

What Founders Need to Know 

A Data Processing Agreement, or DPA, is a contract that sets the rules for how personal data will be handled when one party processes that data on behalf of another.  

Whether a DPA is relevant depends on the data relationship between the parties. 

If your product processes personal information on behalf of a business customer, the customer may require contractual terms governing that processing. Those requirements can come from applicable privacy laws, the customer’s own compliance program, or both. 

Before reviewing the legal language, your team should be able to answer operational questions such as: 

• What customer data will we receive? 

• What will we do with it? 

• Which systems will process it? 

• Which outside vendors will have access to it? 

• Where will processing take place? 

• What can we actually do if the customer asks us to delete or return its data? 

Those answers create the factual foundation for reviewing a DPA. 

What This Looks Like in Practice 

Imagine your startup sells an HR platform to a European company. 

Employees will use the platform, so your system will process names, email addresses, employment information, and other personal data. 

The customer sends you its DPA and identifies itself as the controller and your startup as the processor for certain customer data. 

Then it asks for a list of your sub-processors. 

Your team identifies your cloud-hosting provider, support platform, and several other vendors involved in delivering the service. Some of those vendors process information in the United States. 

Now the customer asks how those international transfers are handled and whether Standard Contractual Clauses (SCCs) are in place where required. 

The DPA also says you must notify the customer of certain security incidents within a specific timeframe and delete or return personal data at the end of the relationship. 

At this point, the important questions are concrete: Do your vendor relationships support the promises you are making? Can your team meet the notification deadline? Can you actually delete the customer’s information from the relevant systems? 

Signing the DPA creates obligations beyond the signature page. 

Three Common Founder Mistakes 

• Treating the DPA as a standard attachment.The provisions may create operational requirements for engineering, security, and other teams. 

• Agreeing to requirements before checking whether the company can perform them. A favorable sales outcome can become a compliance problem if the contract promises capabilities the company does not have. 

• Reviewing the customer relationship without reviewing the vendor chain. Your commitments to a customer may depend on what your own vendors are contractually and technically able to do. 

10-Minute Founder Self-Check 

Before signing a DPA, ask: 

• What personal data will we process for this customer? 

• What role does our company play in that processing? 

• Which vendors or sub-processors will receive the data? 

• Are international data transfers involved? 

• What security commitments are we making? 

• What happens if there is a security incident? 

• Can we satisfy the required notification timeline? 

• Can we return or delete data as promised? 

• Do our vendor agreements support our customer commitments? 

• Does the DPA align with the main commercial agreement? 

What to Do Next 

Before signing a DPA, translate its major obligations into operational questions and confirm the answers with the people responsible for your product, infrastructure, and security. 

If your company regularly handles customer personal data, it may also be worth developing a consistent approach before every new customer sends its own terms.
