Ego Switches Payments in 7 Days, Saving €30k a Month and Boosting App Conversions With Primer

Ego Primer Partnership has transformed how the fashion brand handles payments. Ego gained control and flexibility by switching to Primer. This cut down on extra fees and improved mobile app conversions. This strategic move helped Ego improve its payment stack after its new mobile platform saw huge growth.

By using Primer to reduce its reliance on a single payment service provider (PSP) and efficiently routing payments, Ego has cut payment fees by €30,000 per month and increased revenue through higher conversion rates.

The decision to rethink its payment setup followed the rapid and unexpected success of Ego’s newly launched mobile app. Originally projected to generate just 10% of total revenue, the app quickly surpassed expectations and now drives more than 30%.

But that success brought an unforeseen problem: excessive payment fees.

Ego had entered into a PSP agreement based on lower projected transaction volumes. As its app started outperforming expectations, the commercial terms remained fixed, driving up payment costs and squeezing margins.

Despite efforts to renegotiate, the provider was unwilling to adjust the contract, leaving Ego with a decision over whether to absorb the costs or pause sales on its booming mobile application.

Ego turned to Primer and completed the integration within seven days, including the activation of a new PSP with more favorable rates. The rollout was supported by detailed documentation, real-time communication between teams, and coordinated execution across engineering, product, finance, and legal functions.

The Ego Primer payments setup made it easy to activate PSPs quickly and reduced operational friction, setting a new standard for mobile commerce speed.

Manuel Perez, Head of Product at Ego: “We needed a solution that could move as fast as we do. Primer enabled us to go live with a new PSP in seven days, a timeline that would have been impossible with other providers.”

Since going live, Ego has reduced payment fees by approximately €30,000 per month. Additionally, the company has achieved a 10% increase in checkout conversions on its mobile app by using Primer’s Universal Checkout solution.

“The performance uplift was unexpected, given we hadn’t yet customised the UX,” added Perez. “But Primer’s default checkout proved faster and more reliable than our previous setup.”

Having solved its initial challenge, Ego now plans to extend its use of Primer across additional sales channels, including its webstore, as part of a broader effort to optimize its payments strategy and make payments a lever for growth.

Gabriel Le Roux, Co-founder and CEO at Primer, said: “Ego is an excellent example of what happens when a business takes control of its payments. What started as a cost challenge quickly became something much bigger: an opportunity to move faster, adapt smarter, and future-proof their strategy. That’s the mindset more retailers need to adopt. Payments are business-critical and getting them right gives you a real competitive edge.”

Through the Ego Primer Partnership, the brand achieved meaningful cost savings and enhanced user experience—showing that payments can help a business grow.
