From 2,000 to 4 million transactions a month. A fintech founder launched a payment service provider on Corefy’s white-label infrastructure, skipping at least two years of in-house development and going live two weeks after the demo.The clientThe company is an FCA-licensed payment service provider founded in 2021 by a fintech executive with more than 10 years in payments. It helps online businesses expand globally and sell locally. Merchants get local-currency payment options across regions, available through a single API integration and one dashboard.The challenge: build or launch?Before launch, the founder had to choose between building a payment platform from scratch and running the business on white-label infrastructure. Building in-house meant hiring a development and support team and spending years on technology before processing a single payment.The market helped settle the decision. Several payment providers the founder planned to partner with asked whether the new PSP would integrate with Corefy, because that would make connecting with them faster. The founder then compared Corefy with another payment gateway. Corefy came out ahead on technical capabilities, tech support, and account management.“Choosing between developing a PSP from scratch and opting for Corefy’s white-label solution, I chose the second, as it was faster and more cost-efficient.”Founder & CEOThe solutionThe PSP went from demo to first live transaction in two weeks. The setup covered:Provider connectivity from day one. The client launched with ready-made provider integrations, so it could offer a wide range of currencies and alternative payment methods immediately. When the client needed a provider that wasn’t yet integrated, Corefy built it on request. About 20 such integrations had been delivered by the end of 2025.Routing and cascading. The client worked with a dedicated account manager to configure routing rules for higher conversion.Branded hosted payment page. The page carries the client’s own branding and is translated into dozens of languages, including Chinese, Arabic, Hindi, and Azerbaijani.Operational control. One dashboard, analytics, and monthly reconciliation track income and costs per transaction and catch mismatches with provider statements.Fraud prevention. A rule-based firewall checks each transaction against client-customised lists to reduce fraud and avoid scheme fines.In practice: fixing a conversion leakThe account manager spotted unstable conversion in one currency on the live graphs. The cause turned out to be a single provider with recurring downtime. The team added a second provider as a failover and set cascading rules, so payments the first provider can’t process now go automatically to the second. Failed transactions dropped and conversion recovered.ResultsAt least two years saved by not building an in-house development and support teamTwo weeks from demo to first live transactionAbout 20 new provider integrations delivered on requestGrowth from about 2,000 to about 4 million transactions per monthToday the client’s team configures most of the platform independently and focuses on sales and business development, while Corefy handles infrastructure and maintenance.“At the start of our cooperation with Corefy, the product seemed complicated. But using it now is a pleasure; I’ve learned a lot with our account manager’s help, and it’s now intuitive.”Founder & CEOCase StudiesYescorefy.com/case-studies/payments-client?utm_source=financialit&utm_medium=referral&utm_campaign=psp_case_study&utm_content=case_studies_sectionRead the full case study
