The compliance platform accredited solar retailers and installers use to capture, calculate, and submit STC-eligible jobs. Audit-ready, every time.
Most STC problems happen because someone relied on last year's template, guessed the maths, or lost a photo. 123STC makes all three impossible.
Every checklist, photo requirement, and signature is built from the current CER ruleset. When the rules change, the platform updates. You never have to audit your own templates again.
Postcode zone, deeming period, system size, battery class — all reconciled before the installer leaves the roof. The correct certificate count is calculated automatically, no formula required.
Every completed job ships as a tamper-evident bundle: photos with location data, scanned serials, declarations, and calculations — all packaged together. When the auditor calls, the answer is waiting.
A job moves through seven stages in 123STC. Every stage is a real screen in the product — no guesswork, no switching apps.
Verify ABN, invite your accredited team, enter site address, NMI, system type, and system owner details. The job becomes the container everything lives inside.
Designer, installer, and electrician are assigned by accreditation. Role-specific checklists are generated from current CER rules automatically. No template selection, no version drift.
Installers complete their tasks on the native iOS and Android app. Location-stamped photos and barcode-scanned serials. Works offline, syncs on reconnect.
DocuSign collects all CER-mandated declarations in one place. The platform validates the package and generates your audit-ready bundle. You review and submit.
123STC runs across a web app and a native mobile app. They serve different people in different places but always feed the same job.
Office and retailer-facing. Where jobs are created, participants are assigned, documents are managed, and completed bundles are reviewed before submission.
Rooftop and installer-facing. Purpose-built for the person doing the physical work. Guided tasks, location-stamped photos, barcode scanning. Offline-capable.

Habitat Energy is the authorised STC agent that will purchase the STC and Battery STC's. The account holder can choose to sell the STC's at the time the job is completed on the platform or sell them when the CER approves the job. The choice is yours.
The platform updates automatically. Your checklists, photo requirements, and declaration templates always reflect the current CER ruleset. You do not need to manage template versions.
Yes. The native iOS and Android field app is fully offline-capable. Installers complete checklists, capture photos, and scan serials without a signal. Everything syncs back to the dashboard when they reconnect.
Accredited retailers create an account, verify their ABN, and invite their team. The first job can be running within the hour.
