Compare large-business offers.

Your invoice. Your supplied offers. A clearer comparison.

Compare your supplied offers.

Start with one recent invoice for one supply point. For electricity, add one to three complete retailer offers. For gas, add your two finalist offers and a full year of gas-day data. Choose AI for a checked reading, or use the local reader for supported electricity documents.

See the headline result and where the money goes in a free two-page PDF. Send the sources privately to Bulk to unlock the supporting analysis and ask us to help.

Know what supports the result.

Compare printed rates, dated price changes and supported monthly demand. A full year of interval readings supports different tariff time bands and a seasonal budget.

Electricity includes supported statewide holidays, fixed minimum demand and percentage demand ratchets where dated history supports them. Regional exceptions and unsupported conditions need review. Gas compares fixed or spot offers, delivery costs, minimum take and supported daily or hourly limits. Spot offers need matching prices; unpriced conditions remain visible.

Privacy and supported documents

Selecting files does not send them. Choosing AI reading sends your invoice and offer PDFs securely to OpenAI for this review. The separate Send to Bulk action sends an enquiry and the selected source documents. Neither action signs an agreement or changes your provider.

Without AI, the existing reader reconstructs supported Origin NSW N19 electricity invoices and examined offer schedules using a matching full-year Excel interval workbook. Other documents may need Bulk’s review.

AI reading accepts invoice and offer PDFs with up to 30 pages each. Choose up to 10 MB per file and 40 MB altogether; leave space for the full PDF if you later send the sources to Bulk. Optional interval data can be CSV or XLSX; the native calculation needs the supported XLSX export.

Supplied retailer offers

Electricity: one to three complete PDFs. Gas: two finalist PDFs. Include the schedules and terms.

Usage data — optional for electricity

Electricity: twelve complete months support a seasonal comparison. Include earlier history for demand ratchets, up to 36 months within the file limits. Gas: a full calendar year of gas-day quantities is required; you can add it after reading the offers. Use CSV or XLSX. Without AI, use the supported electricity XLSX export.

Same evidence, clear qualifications

We retain the dates and rates in your supplied offer. We do not treat an expired price as available today or manufacture missing charges, quality flags or export credits.

Choose one invoice and your retailer offers to begin. Gas needs two finalist offers and a full calendar year of gas-day data.
