Carrier surcharge schedules
Turn diesel indexes into a surcharge schedule everyone can audit
Generate a carrier-ready workbook with national and regional diesel indexes, an explicit index-minus-base calculation, fleet MPG, and a twenty-band surcharge table.
The problem
Surcharge disputes happen when the index, base price, fuel economy, and banding method are hidden in different systems.
Activated outcome
A transparent surcharge calculator and publishable band schedule tied to source-timestamped diesel indexes.
One action, a finished workbook
- 1Load the national and five regional diesel indexes.
- 2Set the contract base price and fleet fuel economy.
- 3Publish or export the generated surcharge bands after contract review.

The beta package requests access only to the current spreadsheet, its add-on UI, and outbound HTTPS requests to OilPriceAPI.
A funnel we can measure
- Marketplace listing views and installs
- Successful surcharge-workbook activations
- Campaign-attributed API signups and paid conversions
Successful data requests carry only a product/version header and reviewed market identifiers. Spreadsheet contents, formulas, cells, Google account identity, and API keys are not sent for analytics.
