Software testing that proves your product works — and performs.
AT-TEC supports vendors and integrators with pragmatic QA: functional validation, integrations, regression coverage, and performance metrics for EPOS, payments and retail operations.
Typical engagements: release validation • migration testing • integrations • performance baselining • UAT support
EPOS & product testing
Store workflows, tills, peripherals, payments, back-office sync, reporting and reliability — with measurable acceptance criteria.
Services
Clear scope, fast feedback loops, and reporting stakeholders can actually use.
Functional & Regression Testing
End-to-end store journeys, user roles, cashing up, refunds, promos, tax rules, receipts and audit trails.
- Risk-based regression packs
- Release readiness criteria
- Defect triage & RCA support
Peripheral & Hardware Validation
Printers, drawers, scanners, scales and customer displays—validated across drivers, firmware and OS versions.
- Compatibility matrix
- Soak & endurance runs
- Field issue reproduction
Performance & Reliability
Measure what matters: transaction latency, sync performance, peak-load behaviour, memory/CPU and stability.
- Baseline vs target KPIs
- Load/soak test plans
- Actionable dashboards
How we work
A simple model that scales from a quick release sign-off to longer validation programmes.
1) Define acceptance criteria
We translate your requirements into testable outcomes: workflows, KPIs and “go/no-go” gates.
2) Execute & measure
Structured test cycles with defect triage, daily visibility, and performance baselines where required.
3) Report & sign off
Traceable evidence, risk summary, and an executive-ready release recommendation.
Industries
EPOS and operational systems where downtime and errors cost money.
Retail
Multi-till, inventory, promotions, loyalty and reporting workflows.
Hospitality
Table service, modifiers, kitchen flows, service speed and peak load.
Multi-site operations
Central config, rollouts, upgrades and store-to-HQ sync validation.
