Since 2010 Softjourn team has been maintaining the processing system which is a core of our business; they've done a great job so far! We value the knowledge transfer process as well as excellent development skills!
We were encouraged because Softjourn asked the right questions, involved people with the right experience in to the conversations. Showed good leadership in managing the process of walking them through the sales process, keeping them on track, and has a lot of strong knowledge in the financial area, as they are a small software developer company and there are always so many other things that are pulling us in multiple directions. As well Softjourn shows a lot of experience in multiple programming languages and in combining them in to one product.
The CTO left the company after about eight years, and I needed to replace him. I didn't want to replace him with a single CTO because that created a single point of failure, so I went back to Softjourn. You just can't run an SaaS company without development work. Nearly every time I meet someone, and they're having problems with developers, I tell them "you need to call Softjourn". Softjourn just gives me tremendous peace of mind, and I can't emphasize that enough.
Peter ConnorCo-Founder at BulletThe development team at Softjourn has been fantastic to work with. They are professional and have met our deadlines, while screenshots are pretty cool and I'm excited for our clients. They are going to really appreciate the enhanced functionality of our platform. We have some pretty cool services that are folded into this eWallet that go above and beyond what we currently use. We're very excited to work with Softjourn on this.
Jeff EhneyFounder & CEO at Card TentWe believe in Softjourn's expertise in payments. The team was very responsive and easy to work with. Everything has been positive thus far, and our team is very satisfied with the team's responsiveness. Softjourn team really knows their stuff regarding payments.
We greatly appreciate the work and support Softjourn has provided to Versapay. Their expertise and understanding of our business needs have been invaluable. Softjourn consistently delivers what we ask for, and more. Their team is quick, asks the right questions, and maintains a positive approach throughout. Their deep domain knowledge and business-level insight enable them to spot potential issues early, ensuring the success of our projects.

Fintech Integrations FAQ
We cover the full fintech ecosystem: payments, card issuing, KYC/AML, BaaS, open banking, lending, accounting, cross-border payments, FX, and more.
We're tech-agnostic and have experience with a wide range of systems — including cloud-native apps, microservices, legacy platforms, and mobile/web apps across AWS, Azure, and more.
The best time is during platform planning or when expanding your feature set. Early integration planning ensures smoother architecture, reduces rework, and speeds up time-to-market.
You can — but it depends on your team's experience. Many fintech integrations involve complex flows, compliance risks, and platform nuances. Our team helps you avoid pitfalls and deliver faster, more secure implementations.
Faulty or incomplete integrations can cause delayed transactions, failed KYC checks, reconciliation errors, and even compliance breaches. We help ensure your integrations are robust, secure, and audit-ready.
Yes. We can integrate modern APIs with legacy systems, or design middleware layers to bridge architectural gaps. We've done this for banks, fintech startups, and enterprise platforms.
Absolutely. We build for scale — using cloud-native architectures, asynchronous processing, and performance testing to ensure stability during high-traffic periods like product launches or reporting cycles.
It varies. Simple integrations may take 2–4 weeks, while more complex ones involving multiple services, compliance checks, or legacy platforms may take longer. We provide clear timelines after a brief scoping call.
We monitor API changes and build version-aware integrations. If you choose our maintenance package, we'll handle updates proactively to avoid disruption.
Yes — whether you need a dashboard, reporting module, or a custom UX flow to accompany the integration, our team can handle full-cycle development alongside the connection itself.
Pricing depends on complexity, timeline, and your engagement model (T&M, Fixed Bid, or Dedicated Team). We're happy to provide an estimate after understanding your requirements. Contact us to learn more.
