Technology Built For FinTech
Fast-moving product engineering for FinTech companies, built with the security and compliance discipline financial products require.
FinTech software, explained
Payment and account products handle money in real time. A small error can affect many customers, so accuracy comes first in our design.
We plan each transaction state, such as pending, paid and failed, and how the system recovers from timeouts and retries.
Security and regulatory rules differ by product and market. We confirm which rules apply before the build starts.
Problems in FinTech and how we solve them
The problems
Transaction status is unclear
Customers and support teams cannot tell whether a payment succeeded, failed or is still pending.
Failed payments are handled by hand
Retries and refunds are done manually, which is slow and risky.
Product changes are risky
A small change can break a payment flow, because the code and the data are tightly linked.
Our solutions
Clear transaction states
Every payment has a defined status, shown to customers and support teams.
Retries and recovery
Failed calls are retried within set limits, and each outcome is logged.
Tested payment flows
Payments are tested end to end with test accounts, including failure cases.
Why ELACTRO for FinTech software
We design for accuracy and recovery first, because mistakes in money flows are costly.
We test with test accounts and failure cases before any live customer uses a new flow.

Frequently Asked Questions
How do you handle failed payments?
Each failure has a defined status and a retry rule with limits. Support teams can see what happened and why, without asking an engineer.
Do you build payment processing itself?
We usually connect to an established payment provider rather than building card processing from scratch. We design the flow, the records and the customer views around it.
How do you test a payment product?
We test normal and failure cases with test accounts, and we check that records match at each step before launch.
Which rules will the product need to follow?
Payment, identity and data rules depend on your product and market. We confirm them with you before design and build the controls they require.
