White-Label WordPress Development for Armstrong & Mastercard’s Finicity

Introduction

Armstrong Partnership is a Canadian digital marketing and design agency working with some of the world’s most recognizable brands, including Mastercard. Armstrong partnered with Vertical as their white-label WordPress development team, enabling them to deliver technical solutions at enterprise scale. Discover how Vertical partnered with Armstrong to deliver a custom WordPress Terms & Conditions solution for Mastercard’s Finicity - secure, scalable, multilingual.

Challenge

One of Armstrong’s projects was for Finicity, a North American provider of real-time access to financial data and insights, acquired by Mastercard in 2020. Finicity needed a new Terms & Conditions section to ensure compliance, improve usability, and support multilingual publishing across more than a dozen languages, but without access to the website’s backend.

Solution

Vertical collaborated closely with Armstrong’s marketing team and Finicity’s tech team. Because Mastercard’s security protocols restricted backend access, we built a sandbox environment from scratch, recreating the existing theme and implementing all features independently.

Client Goals

  • Compliance & Regulatory Updates – ensure that the Terms & Conditions matched Mastercard’s strict standards.
  • Improved UX – make browsing and navigation of legal documents more intuitive.
  • Easy Publishing – allow non-technical staff to create and update content with custom fields.
  • Multilingual Support – support more than 12 languages with a dedicated language switcher.
  • Design Continuity – match the existing site’s brand and layout perfectly.
  • Fast Delivery – launch within two weeks.
  • Custom header – separated from the website main menu

Technical Execution

We used Advanced Custom Fields (ACF) + custom code to create reusable templates that Armstrong and Finicity could adapt for future needs. Region-based content and multilingual functionality were implemented through custom-coded solutions. Once complete, we exported all ACF settings and custom code for import on the client’s environment, and provided live support during integration.

  • Environment: WordPress with custom sandbox replication of Finicity’s theme.
  • Backend: ACF + custom PHP for flexible fields and multilingual support.
  • Frontend: Sidebar scrollable menu, multilingual language switcher, responsive design.
  • Security: All development handled off-site, then imported securely per Mastercard guidelines.
  • Collaboration: Regular calls, Slack channels, and feedback in Figma with Armstrong and Finicity teams.

Challenges & Solutions

  • No backend access: Built the solution entirely in a sandbox and exported settings/code for secure client import.
  • Strict brand compliance: Pixel-perfect design replication achieved through detailed design collaboration and Figma review cycles.
  • Tight timeline (2 weeks): Agile sprints with continuous feedback ensured delivery on schedule.
  • Multilingual content: Created a custom translation and switching system, as dedicated plugins were not permitted.
  • Separated custom header: section independent header tabs and links.

Results & Impact

The new Terms & Conditions section delivered measurable improvements:

  • Usability: Users can now navigate terms in an intuitive sidebar format with quick language switching.
  • Compliance: Mastercard and Finicity’s legal teams have confidence in up-to-date regulatory content.
  • Efficiency: Finicity’s non-technical staff can publish and update terms independently in minutes.
  • Scalability: The solution is reusable for future updates and easily extended.

The project received positive feedback from Armstrong, Mastercard, and Finicity stakeholders. It strengthened Vertical’s role as Armstrong’s trusted white-label development partner, leading to further collaborations across Armstrong’s client portfolio.
