● The output

From an address to a signature.

A proposal is not a PDF someone formatted. It is the readable face of one calculation — and the same calculation stands behind the price, the documents and the invoice that follows it.

01 — Generation

How it gets built.

The customer and the address

Pulled from the lead if there is one, so nobody retypes a name or a postcode. The postcode is the input that decides the certificate zone, the state scheme and which activities are even available.

The roof, from above

An aerial scan of that address sizes the array against the real roof planes and returns a yield figure with shading already accounted for.

The system, from the catalogue

Hardware is chosen from the controlled library — never typed in free text — so every line carries a real model number, a datasheet and a written warranty.

Incentives applied

Certificates, program tiers and state schemes resolve against the address and the install date, and are itemised rather than quietly folded into one discounted number.

The price, checked against the floor

The owner can type the figure the customer should pay and the engine works the discount backwards to it. If that would cross the floor, it is refused — not warned about.

Issued as a link

One URL, readable on a phone. Opening it is recorded, so the follow-up call is informed rather than hopeful.

Signed, invoiced, handed over

Signature in the browser re-prices against the locked terms, raises the deposit invoice and moves the job to operations with its paperwork attached.

02 — The result

What the customer actually reads.

The selling half first, the obligations in full behind it, and the same numbers in both.

The price, resolvedSystem, incentives and credits itemised, GST shown, and the net cost after any interest-free loan directly beneath the headline figure.
The system, namedEvery panel, inverter, battery or appliance by make and model — with its datasheet and written warranty attached to that line.
Yield for this roofSized against the aerial scan of their actual roof, with shading already inside the number.
What happens nextThe install sequence, what the customer needs to do, and what the scheme requires of them.
Terms in writingRights, warranty position and consumer-protection information carried in the document itself, not promised in a follow-up email.
A signature that does somethingSigned in the browser; raises the deposit invoice and moves the job into delivery.
Downloadable as sentPrinted page by page as a PDF the customer keeps, matching the link exactly.

Nothing in that document is typed twice. If a figure is wrong, it is wrong in the engine — which means it is wrong once, findable, and fixable for every quote at the same time.
