Platform modules

Seven modules.
One workflow.

Every module feeds the next. Ingested source documents populate the engine. Scenarios flow into reports. Approved reports land in the vault. Nothing is re-entered.

Single source of truth for every municipality you cover.

See every active CoS study, NERSA submission deadline, and tariff trend on one screen — across all 257 municipalities. Drill into any metro in two clicks.

Compliance engine

NERSA thresholds.
Checked automatically.

Every scenario is validated against NERSA benchmarks the moment you run it. You see compliance status inline — not in a rejection letter six weeks later.

Loaded from the active NERSA guideline version in your session. When guidelines update, thresholds update automatically. No manual maintenance.
