Skyline Business Intelligence System helps businesses and researchers explore datasets, understand patterns, test models and receive clear, evidence-based reports.
Clients must submit an EcoCash payment reference. Analysis is enabled only after the administrator manually verifies payment.

Administrator portal
Private workspace for checking EcoCash references and managing approved analysis requests.
From raw data to clear decisions.
Describe the problem, submit your EcoCash payment reference, and wait for manual approval. Once approved, the system unlocks dataset analysis automatically. It includes data-quality checks, descriptive statistics, charts, outlier screening, supervised learning baselines, clustering and an exportable report.

Scope and responsible use
This system provides useful baseline analysis, not guaranteed scientific truth. Model quality depends on data quality, sample size, representativeness, target definition and validation. Correlation does not prove causation. For clinical, legal, safety-critical or major financial decisions, obtain qualified review. This is not certified ZIMRA fiscal-device integration or official tax filing software.
Privacy note: uploaded CSV files are deleted after processing. Analysis requests, jobs and reports are scheduled for deletion after the configured retention period (90 days by default). Expired sessions and temporary security records are also cleaned up. Accounts are retained until a separate account-deletion process is provided. Avoid uploading unnecessary personal or confidential information.
