STC process and payment timing

STC payment terms: is 20 days really worse than 1 day?

Short answer

Twenty day terms mean roughly three weeks of certificate value sits unpaid. For a crew lodging ten claims a week, that can be tens of thousands of dollars of float, so 1 day terms often win even at a slightly lower headline rate.

Payment terms are the most underrated line on a trader’s rate card. A rate that looks 20 cents better can be a worse deal once you count the days.

A worked example

Assume a 6.6 kW system in zone 3 earns 45 STCs. At roughly $38 each, that is about $1,710 per job. If your crew lodges 10 such claims a week:

20 day terms 1 day terms
Value lodged per week about $17,100 about $17,100
Money outstanding at any time about $50,000 or more about $2,500
Cash tied up Roughly three weeks of claims Roughly a day

Three weeks of certificate value unpaid means you are funding your trader. If you are carrying that on credit, overdraft or supplier delays, the interest or lost discounts quickly outweigh a small rate edge.

The decision

Convert the delay into dollars. If your cost of funds is, say, 10 percent a year, $50,000 tied up costs about $5,000 over a year, before counting the opportunities you missed. Compare that to the rate difference. For most crews, fast settlement wins.

Other things terms hide

Rate lock timing, rejection handling and clawbacks. A 20 day term with an unlocked rate leaves you exposed to price moves while you wait. A 1 day term with an unclear clawback has its own risk. Ask both questions.

From the desk: work out your weekly lodgement value and multiply by the days of delay divided by seven. That is your float. Then decide if the rate is worth it.

What this means for installers

Energy Merchants settles established partners within 24 hours, with a first claim in 48 to 72 hours, rate locked on lodgement of a complete claim and zero fees. See the pricing page, how it works and how long STC payment should take.

There is also the matter of risk. A trader that owes you tens of thousands of dollars for three weeks is a creditor you carry on your balance sheet. Faster settlement shrinks that exposure, which matters if the trader’s financial strength is anything less than certain. Short terms are a cheap way of limiting your counterparty risk.

To turn this into your own numbers, take last month’s total certificate value, divide by thirty for a daily figure and multiply by your trader’s payment days. The result is the money you are lending out, free of charge, every single day. Seeing it as a real dollar number tends to focus the mind far more than comparing cents per certificate.
