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, so 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.
