What we found
Patterns from two fintech engagements
-
No dedicated QA while the risk kept growing
Neither platform started with a QA function. The payment platform ran on sporadic, PO-led manual testing with no documentation — an absence that became, as that case study puts it, “a serious risk.” The investment platform's developer-run Postman checks carried the same kind of exposure: “a significant reliability and compliance risk” for a platform moving financial instruments.
-
API docs that were never turned into test cases
The investment platform had Swagger documentation for every endpoint, but no test cases and no automation behind it — testing meant a developer running basic checks in Postman. Good documentation does not test itself.
-
A bug in a transaction flow isn't cosmetic
When the product moves money or securities, the errors that matter most hide in transaction processing and calculation logic. That's exactly where we found critical transaction errors on the investment platform, with a direct impact on financial reliability.
-
QA that has to survive after the consultants leave
The investment platform's engagement came with one explicit requirement: everything had to transfer to the client's own team by the end. We built the test collections in Postman Flows specifically so any team member could run them without deep API knowledge.
Where to start
The services these two engagements actually used
API testing, automation testing, and QA audits ran on both fintech engagements below. Manual testing built the payment platform's initial coverage, and automation scaled the regression work from there.
Automation Testing
Scalable test suites that run on every commit, giving your team instant confidence on every build.
Used on both fintech engagements
API Testing
Full coverage of your endpoints, contracts, and integrations — before they break in production.
Used on both fintech engagements
QA Audit
A complete health check of your quality processes, tooling, and team — with a clear action plan.
Used on both fintech engagements
Manual Testing
Human-led testing that catches what automation misses — UX issues, edge cases, and real-world flows.
Used on one of the two fintech engagements
