About the client
Our client is an established European PSP headquartered in Vilnius, Lithuania, serving mostly high-risk online merchants across Europe. The company positions itself as a global payment processing provider offering instant payments and payouts, with 50+ payment methods spanning card payments and alternative payment solutions.
Core challenges before migration
Earlier, our client relied on a third-party gateway to handle payment flows. It worked at the start, but over time, the business outgrew its technical ceiling. The biggest blocker was the lack of multitenancy depth. The PSP needed a structure that allowed each merchant to have a separate commerce account, with its own access and isolated routing and firewall logic.
At the same time, our client's expansion required frequent onboarding of new providers and acquirers, adjustments to routing by merchant and geography, and maintaining predictable reconciliation. Their existing partner lacked the feature set to meet those needs, and the migration became a matter of business continuity.
Why the client chose Corefy
The client sought a platform that would eliminate multitenancy and routing constraints immediately, while remaining scalable as the merchant portfolio grew. Moreover, they had an urgent migration timeline and needed a new solution to be live within weeks.
The client evaluated alternatives and chose Corefy because it offered the exact infrastructure they lacked:
- ability to create separate merchant environments with individual access
- white-label Merchant portal to serve merchants without building a back office
- Firewall-level routing and risk configuration per account
- fast onboarding with structured guides and hands-on support
- ability to request new integrations on demand
Onboarding: live in 10 days
From project kickoff to going live, the PSP was onboarded in 10 days — a timeline close to a record for a PSP-level rollout.
What those 10 days included:
- MVP deployment
- Rolling out their Merchant portal
- Configuring first payment routing and Firewall schemes
- Setting up Analytics & Reporting for reconciliation
Two factors made this timeline possible. First, the client came in with a technically strong team and had already secured all required MIDs, so nothing on the client's side slowed the launch. Second, our Customer Success and Integration teams operated on a sprint cadence, sharing clear onboarding guides, answering questions promptly, and coordinating next steps in real time.
Corefy in the client's day-to-day operations
After migration, the PSP actively uses three Corefy tools that map directly to their operational model.
Merchant portal
They rolled out the Merchant portal as a white-label back office for merchants. Each merchant has their own access to a separate commerce account, allowing them to monitor transactions, track balances, and export data without waiting for PSP support. This reduced day-to-day operational load on the PSP team and made merchant servicing more scalable.
Firewall
The PSP also uses the Firewall to configure routing and risk management separately for every commerce account. That separation is essential for high-risk merchants because routing logic often needs to be tailored to merchant type, traffic patterns, or specific acquirer requirements. With per-account schemes, changes in one merchant's setup don't affect others, and performance can be controlled at a granular level.
Analytics & Reporting
Corefy Analytics & Reporting became the PSP's single source of truth across providers and accounts for:
- reconciliations across multiple acquirers/PSPs,
- performance monitoring by account and route,
- spotting declines or provider instability early.
Instead of pulling data from multiple provider dashboards, they now see processing performance across accounts in one place and can quickly export standardised reports for finance workflows.
What we built together: custom work delivered by Corefy
Beyond the core platform launch, our client required additional functionality to support their merchants and accelerate growth.
- We built a custom hosted payment page (HPP) based on their design concept. The PSP wanted a consistent, trusted checkout experience under its brand without requiring merchants to build or host their own pages. The custom HPP solved that and ensured a unified UX across their merchant network.
- Our Integration team implemented 29 custom connections with payment providers and acquirers on the client's request by the end of 2025. This is a crucial scaling lever for PSPs in high-risk verticals: new merchants and new regions often require specific provider coverage. With custom integrations handled on our side, the PSP could expand their payment offerings without building and maintaining every connection internally.
Alongside the Corefy rollout, the client also wanted to expand their payment network for both card processing and payouts and add more local and alternative methods (including POLi, BLIK, Sofort, Multibanco, Neteller, Paysafecard, and Skrill). Leveraging our strong industry network, we introduced them to a shortlist of vetted, relevant providers — and they’re currently in active negotiations.
Results and operational impact
The PSP moved from its previous white-label gateway to Corefy in just ten days, demonstrating that switching payment infrastructure doesn't have to be painful when both parties are motivated, prepared, and willing to cooperate.
What changed for our client:
- Migration without downtime pressure thanks to a 10-day go-live.
- Сlean merchant separation and access rights.
- Faster scaling through rapid custom provider/acquirer integrations.
- Self-service merchants via a white-label portal, reducing manual PSP workload.
- Reliable reconciliations and unified performance visibility using Analytics.
Based on their previous limitations and high-risk merchant focus, the migration also prevented two common scaling risks:
- Merchant churn caused by slow provider launches. In high-risk verticals, the lack of local or preferred methods quickly leads merchants to move elsewhere. With Corefy's 550+ integrations and faster provider rollout, the PSP avoided that bottleneck.
- Revenue loss from routing rigidity. When routing can't be isolated by merchant/geo, spikes in one segment can spill over into others. Per-account Firewall schemes reduced cross-merchant risk and kept performance controllable.
Conclusion
This PSP approached Corefy seeking speed, multitenancy, and technical depth. Ten days later, they were live with a scalable orchestration layer that supports their business model today and removes constraints for the future. We continue working together on new integrations and merchant-level routing optimisation as their European high-risk portfolio grows.
