What is the onboarding checklist for a new STC trader?

Short answer

To onboard with an STC trader you will typically need your ABN and GST status, bank details, installer accreditation numbers, a signed RCTI agreement and the trader's terms. Then send one small test claim before moving volume.

Joining a trader is mostly paperwork, and most delays come from missing items. Gather these first.

Business and tax details

  • ABN and entity name, exactly as registered.
  • GST registration status. It changes how payment and tax invoices work.
  • Bank account in the business name for settlement.
  • A signed RCTI agreement, if the trader issues recipient-created tax invoices. See RCTI, GST and ABN.

Accreditation and installer details

  • Installer accreditation numbers and any licences relevant to the work: solar, battery, hot water or heat pump.
  • Certificate holder or registry details, if you have registered in the REC Registry.
  • Contact for compliance questions, so queries reach the right person.

Paperwork for the first job

Have a template assignment form ready, see the STC assignment form guide, and photos taken to the photo requirements. For batteries, the battery submission guide applies.

The test claim

Send one small job first. Check the rate applied, the time to payment, the RCTI and how the portal handled any query. If it all lines up, move more volume.

From the desk: new partners usually take a little longer on the first claim while details are verified. Plan your cash around that, not the best case.

What this means for installers

Treat onboarding as a short project with a checklist and an owner in your office. At Energy Merchants the first claim for a new partner clears in 48 to 72 hours while we verify your details, then you are on 24-hour settlement, and your named account manager walks you through lodging. You can start trading any time, compare rates on the pricing page and see the how it works overview. If you are coming from another trader, switching mid-month has the sequence.

Follow-up questions

People also ask

How long does onboarding take?
It depends on how quickly you return documents. A complete set can be turned around fast, but verification of new partners adds time to the first claim.
Do I need an RCTI agreement?
Most traders issue a recipient-created tax invoice on your behalf, which needs an agreement between you and the trader.
