In-house vs. Third-party Solutions for Mastercard AN4569 Compliance: Making the right choice

Ondřej Slivka
min read

When it comes to compliance with Mastercard AN4569 and the implementation of payment data enrichment tools, businesses often find themselves at a crossroads — whether to develop an in-house solution or leverage third-party expertise. While the allure of internal development might be tempting, practical considerations and industry insights often favour the efficiency and effectiveness of external solutions.

The pitfalls of in-house development

Developing an in-house payment data enrichment tool involves creating a comprehensive merchant knowledge base. While this may sound like a viable option at first, the practicalities tell a different story. The process is inherently time-consuming, diverting valuable resources away from core business activities. Furthermore, it's a more expensive endeavor compared to the cost-effective alternative of opting for external solutions.

Maintenance and updates become an ongoing challenge with an in-house solution. Tasks such as adding new entries, removing outdated ones, and implementing changes demand significant manpower. This continuous effort to ensure data correctness can lead to a drain on resources that could be better allocated elsewhere within the organization.

The reality of data correctness

Maintaining data correctness is a critical aspect of compliance with Mastercard AN4569. Notably, the fact that most businesses rebrand every 7-10 years and 8% of logos change yearly underscores the dynamic nature of merchant information. An in-house solution might struggle to keep up with these changes, potentially compromising the accuracy and completeness of payment data.

Below you can see an example of the data correctness process put in place.

Speed and efficiency at the center

With digital transactions, timing is an absolute key factor. Building an in-house solution could take months, consuming precious time and delaying compliance efforts. In contrast, deploying an external solution, such as partnering with a third-party provider, usually requires just a few weeks. This speed is crucial for businesses seeking swift compliance with Mastercard AN4569 while minimizing disruption to their operations.

Why collaborating with a third-party is the way to go

For most companies, the favoured approach for enhancing payment data and complying with Mastercard AN4569 is collaborating with a third-party solution provider. External solutions bring specialized expertise, efficiency, and cost-effectiveness to the table. With a dedicated focus on payment data enrichment, third-party providers can navigate the complexities of compliance more effectively than businesses attempting to manage it internally.  

In conclusion, the decision between in-house and third-party solutions for Mastercard AN4569 compliance is vital. While the idea of internal development may be appealing, the practicalities often tip the scales in favor of external solutions, ensuring businesses can navigate the intricacies of payment data enrichment with speed, accuracy, and efficiency.
