Tomorrow’s finance: our response to emerging trends
Financial services never stand still – and neither do we. At SumatoSoft, we watch what’s next, test new technologies early, and craft fintech solutions that help you adapt faster than your competition. We constantly adjust our fintech software development services to maximize the value of our Clients.
We don’t just follow fintech trends – we turn them into practical tools that help you lead.
Here’s how we prepare your business for the finance of tomorrow:
Blockchain
Trust and transparency are non-negotiable in finance. Blockchain makes transactions tamper-proof and traceable. We apply it to build secure payment systems, automate agreements through smart contracts, and enable fast, transparent cross-border transfers, cutting fraud and hidden costs along the way.
Artificial intelligence and machine learning
AI and ML push financial operations from reactive to predictive. We embed them in fraud detection engines that learn from new threats, smart scoring tools that assess risk in real time, and virtual assistants that give customers instant, human-like help, delivering smarter tech, safer transactions, and happier Clients.
Lending automation
Borrowers expect fast answers; lenders need accuracy and compliance. Our lending automation takes care of routine checks, verifies data instantly, and speeds up approvals, ensuring fewer errors, faster funding, and a lending process that scales with demand.
Regulatory technology (RegTech)
Regulations tighten every year, but compliance shouldn’t slow you down. We build RegTech tools that monitor new rules, automate reporting, and keep your systems audit-ready, reducing surprises, lowering compliance costs, and freeing up time for strategy.
Digital payments and mobile wallets
As cash fades, digital payments must be fast and secure – everywhere. We develop systems and wallets that handle tap-and-go cards, QR codes at the checkout, and crypto payments for next-gen customers, keeping each transaction protected and frictionless.
Sustainable & socially responsible investing (SRI)
Modern investors want returns and impact. We design SRI platforms that let users choose green and ethical assets, track real-world impact, and balance profit with purpose, connecting your brand with a growing community of responsible investors.

They shouldered the burden of constantly updating a project management tool with a high level of detail and were committed to producing the best possible solution.
I was impressed by SumatoSoft’s prices, especially for the project I wanted to do and in comparison to the quotes I received from a lot of other companies.
Also, their communication skills were great; it never felt like a long-distance project. It felt like SumatoSoft was working next door because their project manager was always keeping me updated. Initially.
We tried another company that one of our partners had used but they didn’t work out. I feel that SumatoSoft does a better investigation of what we’re asking for. They tell us how they plan to do a task and ask if that works for us. We chose them because their method worked with us.
The Rivalfox had the pleasure to work with SumatoSoft in building out core portions of our product, and the results really couldn’t have been better.
SumatoSoft provided us with engineering expertise, enthusiasm and great people that were focused on creating quality features quickly.
SumatoSoft is great in every regard including costs, professionalism, transparency, and willingness to guide. I think they were great advisors early on when we weren’t ready with a fully fleshed idea that could go to market.
They know the business and startup scene as well globally.
SumatoSoft is the firm to work with if you want to keep up to high standards. The professional workflows they stick to result in exceptional quality.

Our streamlined fintech development process
Our development process balances speed, transparency, and strict quality control – so you get secure fintech software without delays or surprises. Here’s what working with us on fintech software development looks like:
Every fintech project starts with clear questions: What are your goals? Who will use it? What regulations apply? We turn these answers into realistic timelines, cost estimates, and a step-by-step plan that everyone can trust.
Next, we sketch how everything fits together. Architects lay out a secure, scalable financial software system, while designers craft user flows that feel effortless – all with compliance built in from the first wireframe.
Instead of one big release, we build the fintech software in short sprints. You get working features to review every 2–4 weeks, plus updates through CI/CD pipelines to catch bugs early and keep progress visible.
No shortcuts here. Each release goes through automated checks and manual tests for functionality, security, and regulatory compliance of your financial software. The goal: zero critical issues, every time.
We deploy safely to your servers or cloud of choice and connect new financial software to your existing cores, payment gateways, or other systems – all without disrupting daily operations.
Going live is just the start. We stay on hand to monitor performance, push updates, and add new features as your business grows – so your fintech solution stays secure and competitive long-term.
