Custom core-banking & fintech software, engineered carefully.
We build custom banking and fintech software — double-entry ledgers, transaction and settlement dashboards, reconciliation, real-time fraud and limit checks, and the back-office tooling around them. This is the vertical where correctness matters most, so we build it deliberately, to your institution's compliance and audit requirements, and you work directly with the engineer writing the code.
What a custom core banking software build includes
Every project is bespoke — this is the ground the work usually covers.
Ledgers & transactions
Double-entry ledgers, balances, holds and postings with a full immutable audit trail — the correctness core everything else sits on.
Dashboards & operations
Real-time transaction, settlement and exposure dashboards for ops and finance teams, with drill-down and export.
Reconciliation
Automated reconciliation across accounts, gateways and statements, with clean exception queues instead of spreadsheets.
Fraud & limit checks
Configurable real-time rules — velocity, thresholds, anomaly flags — that score and hold transactions before they clear.
Integrations
Payment rails, card networks, KYC/AML providers and reporting endpoints, wrapped behind interfaces you can swap without a rewrite.
Security & audit
Role-based access, encryption, and audit logging built to the standards your auditors and regulators expect.
Questions we get asked
Are you a regulated bank or a certified processor?
No — and we won't claim to be. We are a software studio that builds banking and fintech software to the compliance and security requirements you and your regulators define. Certifications (SOC 2, PCI DSS, ISO 27001) attach to your organisation and infrastructure; we build the system so it can meet them, and we're candid about that line rather than overselling it.
How do you handle correctness and auditability in financial software?
The ledger is designed double-entry and append-only, every state change is logged with who/when/why, and money movements are covered by tests that assert balances reconcile. We favour boring, verifiable designs over clever ones here — in banking, predictability is the feature.
Build vs. buy for core banking?
For a full regulated core, a proven vendor platform is often the right call. Custom software earns its place around the edges and above the core — reconciliation, dashboards, fraud rules, internal tooling and integrations that vendor platforms do poorly or charge heavily for. We'll tell you plainly which parts are worth building and which aren't.
Who can see the code and the data?
You. The code ships to your repository, runs on your infrastructure, and the data stays in your controlled environment. You're never handing your financial system to a black box you can't inspect.
A fraud-check dashboard, shown honestly
The banking widget on our homepage — a live transaction feed with a fraud-confidence score — is an illustrative build with simulated data, not a deployed banking system or a real client's numbers. We use it to make one slice tangible: a transaction arrives, rules score it, a held payment surfaces for review. A real engagement is scoped from your rails, your risk rules and your audit requirements, and built one verifiable slice at a time.
Why build it with SoftSolutionsAI
You talk to the engineer
Not an account manager. The person who designs and writes the code is the person you message on WhatsApp — before, during and long after launch.
A working demo every Friday
One process, six stages, a real build you can click through each week. Scope stays honest and you're never waiting months to see something real.
You own it
Code ships to your repository, runs on your servers, and the data stays in your database. No per-seat licence, no lock-in, no vendor who can switch you off.
