Fair questions, straight answers.

Seeing your saving is free. Treehouse is A$2.99 a month (A$29 a year), and Village, for three homes, A$5.99 (A$59 a year). That's the catch: you pay us, so retailers don't have to.

No. We take no commissions, referral fees or sponsorships from any retailer, so no plan can buy its way up your reading. Your membership pays for BillWizard, which keeps us firmly on your side.

The whole published market. We price every generally available offer in your area, straight from the regulator's own plan data. No retailer pays us anything, so none of them gets left out.

Just a recent electricity or gas bill, as a PDF or a photo, with all its pages if you can. It carries your tariff, your usage and your meter details: everything the Wizard needs to price you.

Our robot reads it, in Australia, and we keep the figures so the Wizard can watch the market for you. We don't keep the bill itself, we never sell your information, and you can delete any bill.

Energy Made Easy is free and independent too, and we rate it. There you enter your details and read the plans yourself. BillWizard reads your bill, does the pricing and keeps checking every day.

At the end of November, right here on billwizard.com.au, where you'll sign up and pay. Your first reading takes about five minutes. Until then, follow Software Cowboy on LinkedIn for launch day.

Yes. The Wizard reads your solar exports from your bill and prices every plan's feed-in tariff, tiers included, so a plan that pays more for exports is weighed against what it charges you.

Yes. Upload a gas bill and the Wizard prices it against the gas plans in your area in the same way. Membership covers electricity and gas together, so there's nothing extra to pay for gas.

New South Wales, Victoria, Queensland, South Australia, the ACT and Tasmania, where households choose their retailer. Western Australia and the NT aren't covered: most homes can't choose.

No. The Wizard shows you the plans and the saving, and you switch with the new retailer yourself, usually online in minutes. Nothing changes until you choose, and nobody will call you.

BillWizard is for households, so its plans and readings are for homes. A business bill gets a free Business Bill Check, and Treehouse and Village each cover one business property.

Yes. Cancel from Settings whenever you like. It takes effect at the end of the period you've paid for, and you keep access until then. Your figures stay yours to delete at any time.

As accurate as your bill allows: each plan is priced on its own terms against your real usage. Your future usage and prices will differ, so every saving is shown as an estimate, not a promise.
