One build sheet that totals itself — every card feeds the live receipt, top to bottom:
- The order money accruessection subtotals → gross total → + margin → sell before credits → − upfront credits → quote ex GST → + 10% GST.
- Upfront vs annualSTC, VEEC and PDRS credits reduce the quote. LGC revenue is annual income ($/yr) — never deducted from the quote.
- Margin vs markupmargin is a share of the sell price, markup a share of cost; whole-quote or per line item. The receipt caption shows the effective markup either way.
- The metersSystem $/W is the quote ex GST net of upfront credits; Battery $/kWh is the battery section cost per kWh.
- STCs can read $0existing on-site solar can consume the 100 kW small-scale allocation — that production earns LGCs instead.
- SectionsEquipment and Battery are core; other built-ins can be removed and restored. Section sets save your layout as a reusable template.
Scheme rules and rates live in the incentives guide — this page only decides what lands on the quote.
The Pricing page is one build sheet that totals itself. The left column is the ledger — cost sections and the Credits & Incentives band. The right column is the live Quote Summary receipt and the Margin card. Every number you type on the left lands on the receipt immediately, in a fixed order. This page explains that order and the handful of conventions the sheet relies on.
The order money accrues
The receipt reads top-down in the exact order the maths runs:
- Section subtotals — Equipment, Battery, Installation & Labour and the rest each sum their own line items.
- Gross total — the section subtotals added together. Your cost.
- + Margin — your profit, from the Margin card.
- Sell before credits — gross plus margin: what the job sells for before any scheme money.
- − Upfront credits — STCs, VEECs, battery STCs and PDRS, deducted line by line.
- Quote ex GST, then + 10% GST, then the inc-GST hero figure — the number the customer signs.
Margin is applied before credits come off: you earn margin on the work, and the schemes then discount the customer’s price. GST is calculated on the credited (post-incentive) amount.
Upfront credits vs annual revenue
The Credits & Incentives band mixes two kinds of scheme money, and the receipt treats them very differently:
- Upfront credits (STCs, VEECs, PDRS) are one-off point-of-sale discounts. They appear as deduction rows on the receipt and reduce the quote.
- LGC revenue is never deducted. Large-scale generation certificates accrue every year the system runs, so they show as a separate $/yr callout under the quote — income the customer earns, not a discount you fund.
What each scheme is and how the certificate maths works lives in Australian solar incentives explained — the build sheet only decides what lands on the quote.
Why STCs can legitimately read $0
The small-scale scheme covers the first 100 kW at a site. If existing on-site solar has already consumed that allocation, the new system creates no STCs — the row reads $0 and the card says why. That production isn’t lost: past 100 kW the system registers as a power station and earns LGCs instead, which is exactly the $/yr callout above.
Margin vs markup
The Margin card offers two bases and two modes. The bases are different maths:
- Markup on cost — the percentage goes on top of cost. 20% markup on $10,000 adds $2,000.
- Margin on sell — the percentage is your share of the sell price. 20% margin means the $10,000 cost is 80% of sell, so sell is $12,500 and you keep $2,500. Margin on sell always adds more dollars than the same markup number.
The mode picks where the percentage applies: Whole quote spreads one percentage across everything; Per line item lets each line carry its own. Whichever combination you use, the two figures on screen reconcile it: the Margin card’s hero shows the effective % on sell, and the receipt caption restates the same money as the effective markup — same dollars, two lenses.
The meters
The strip next to the page title tracks the benchmarks installers actually compare:
- Solar PV / Battery — the system sizes the sheet is pricing, from the design stages.
- System $/W — the quote ex GST, net of upfront credits, divided by system watts. This is the industry “dollars per watt” figure.
- Battery $/kWh — the Battery section cost divided by battery kWh: hardware and its install lines, before margin and credits.
Sections: core, removable, custom
Equipment and Battery are core — they hold the design-stage hardware and can’t be removed (Battery appears only when the design has a battery). The other built-ins can be removed and later restored from the “Add section” chips, and you can add custom sections for anything the built-ins don’t cover — every section totals into the receipt the same way.
