Test faster. Understand the risk. Release with confidence.
From an independent assessment to ongoing Quality Engineering, we shape the work around your product, release risk and the evidence you need.
Product Quality Assessment
Know where your product stands before your users tell you.
Built an MVP, SaaS product, mobile app, AI-generated application or major new feature and are not sure whether it is ready? QA SONIC performs an independent Quality Engineering assessment focused on the workflows and risks that matter most.
What we can cover
- Core user journeys
- Functional behavior
- Business-critical workflows
- Edge and negative scenarios
- Integrations and error handling
- Data integrity
- Cross-browser and device behavior
- Usability issues
- Release blockers and regression risk
What you receive
- Structured findings with evidence
- Risk prioritization
- Coverage summary
- Critical workflow assessment
- Release observations
- Recommended next actions
Web & Mobile Quality Engineering
Comprehensive testing built around real product risk.
Not every feature deserves the same testing effort. We begin by understanding how your product works, who uses it, which workflows are critical and where failures would have the greatest impact. We then design the appropriate mix of functional, exploratory, regression, integration, compatibility and device coverage.
What we can cover
- Functional and exploratory testing
- Regression and integration testing
- Cross-browser and responsive testing
- Mobile testing
- Usability, boundary and negative testing
- Data validation and release verification
What you receive
- Risk-informed coverage
- Actionable findings
- Regression evidence
- Release-focused reporting
Regression Automation
Automate repetitive regression work with tests your team owns.
QA SONIC designs maintainable automation around the workflows that create the most repeated testing effort and release risk. Where appropriate, we use established frameworks and integrate directly with your repositories and CI/CD pipelines instead of forcing a proprietary testing subscription.
What we can cover
- Automation strategy
- Framework setup or assessment
- Web, mobile and API automation
- CI/CD integration
- Parallel execution and reporting
- Flaky-test investigation
- Maintenance and expansion
What you receive
- Source code
- Automation framework
- Test suite
- CI integration
- Documentation and handover
API & Integration Testing
Test the systems your users cannot see.
Many serious failures happen behind the interface. We validate APIs, third-party services, authentication, data flow, webhooks, error handling and failure recovery so integration risk is understood before it reaches production.
What we can cover
- Request/response behavior
- Authentication and authorization
- Data validation
- Third-party services and webhooks
- Timeouts and failure recovery
- State transitions and synchronization
What you receive
- API findings
- Automated checks where valuable
- Integration risk summary
- Reproduction evidence
Payment & Transaction Testing
Protect the workflows directly connected to revenue.
Payment failures can create lost revenue, duplicate charges, failed subscriptions, broken refunds and customer-support incidents. We test the full transaction lifecycle instead of only the happy path.
What we can cover
- Checkout and authorization
- Failed payments and retries
- Refunds and partial refunds
- Subscriptions and recurring billing
- Cancellations and payment states
- Gateway webhooks
- Currency and error scenarios
What you receive
- Transaction coverage map
- High-risk findings
- Gateway-specific evidence
- Regression recommendations
Performance Engineering
Find performance risks before users experience them.
Functional correctness is only part of software quality. QA SONIC helps teams understand response times, concurrent-user behavior, bottlenecks, degradation and scalability risk, then translates performance data into engineering actions.
What we can cover
- Load and API performance
- Throughput and response time
- Bottleneck discovery
- Slow-page and resource analysis
- Failure thresholds
- Performance regression
What you receive
- Performance test plan
- Execution evidence
- Bottleneck summary
- Recommended next investigations
AI & LLM Quality Evaluation
AI features need more than traditional pass/fail testing.
AI-powered features can be technically available while still producing inaccurate, irrelevant, inconsistent or unreliable results. QA SONIC combines structured evaluation, repeatable datasets, automated evaluation techniques and human review to understand model and feature quality.
What we can cover
- Response quality and relevance
- Consistency
- Hallucination behavior
- Expected-answer alignment
- Prompt and model regression
- Edge cases and failure handling
- RAG evaluation
- Human-reviewed evaluation sets
What you receive
- Evaluation strategy
- Test/evaluation dataset
- Automated and human-reviewed results
- Risk and regression findings
Release Readiness Testing
Need an independent answer before a critical launch?
For major releases, migrations and high-risk changes, QA SONIC performs focused release-readiness testing around critical workflows, known risks, regression exposure, unresolved defects and integration dependencies.
What we can cover
- Critical workflow coverage
- Known risk areas
- Regression exposure
- Open high-impact defects
- Integration risk
- Coverage gaps
- Release observations
What you receive
- What was tested
- What remains uncertain
- Critical risks
- Recommended release action
Embedded Quality Engineering
Add experienced Quality Engineering capacity when you need it.
QA SONIC engineers can work alongside development and product teams for defined periods or ongoing engagements, adding functional testing, automation, API testing, performance work and process improvement without requiring immediate permanent hiring.
What we can cover
- Sprint and release testing
- Test planning
- Automation
- API and performance testing
- Quality reporting
- Process and CI/CD improvement
What you receive
- Agreed capacity and responsibilities
- Defined reporting cadence
- Quality deliverables
- Knowledge transfer
White-Label Quality Engineering
Add QA capability to your agency without building it from scratch.
QA SONIC can operate as a white-label Quality Engineering partner for development agencies that need reliable QA capability for specific projects, client accounts or delivery periods.
What we can cover
- Client projects
- Short-term or dedicated capacity
- Automation projects
- Release assessments
- Specialist testing
- Reporting and documentation
What you receive
- Delivery model aligned to your agency
- Confidentiality
- Consistent reporting
- Flexible scaling
