STC process and payment timing

What do I need to start trading STCs?

Short answer

To start trading STCs you need an ABN and GST position, accreditation to install, bank details, a way to capture photos and signed assignment forms, and a trader to lodge and pay for the claims. Setup can take a day.

Starting is straightforward if you have your paperwork in order. Most of what you need is things a working installer already has.

The checklist

  • ABN and GST status. Traders pay businesses, and many issue a recipient created tax invoice. See RCTI, GST and ABN for STC payments.
  • Accreditation. Your relevant accreditation to install, such as Clean Energy Council accreditation, and electrical licensing. Batteries require an accredited installer as part of the program.
  • Bank details. For payment, matched to your business name.
  • Photo routine. A phone and a checklist, using the photo requirements guide.
  • Assignment forms. A signed form for each job, per the assignment form guide.
  • A trader. One that fits your volume and cash flow needs.

Choosing the trader

Compare rate, lock, fees and speed. Ask about onboarding: some providers are quick, others take weeks of paperwork. Our trader checklist gives a short list of questions.

Your first claim

Expect extra verification on the first one. At Energy Merchants it takes 48 to 72 hours as we check your details, then you move to 24-hour settlement. Starting with a straightforward job is sensible.

From the desk: before your first claim, send us a sample photo set. We will tell you what would pass and what would not, without it costing a claim.

What this means for installers

You can start trading with Energy Merchants in minutes: start trading, and the desk will take it from there. Read how it works, the Partner Program and the pricing page first if you want the detail.

Finally, expect to give a little information up front. Reputable traders verify identity and accreditation because the registry requires accurate details, and it protects you as much as them. Having your documents in one folder, with ABN, licence, accreditation and bank details, usually halves the time to get started.

If you also install batteries or heat pumps, ask at the outset whether the provider handles those certificates too. Using one trader for STCs, battery STCs and VEECs means one onboarding process, one account manager and one set of terms, which is simpler than juggling several providers as your work diversifies. See the battery STC pillar and the VEEC pillar.
