Delivery Check

Compare a delivery invoice with before-and-after tank depths, entered consumption and a user-chosen reading tolerance. Save the tank chart and inputs together for later review.

1. Open Check, create a delivery check, and select the chart matching your installed tank and orientation.
2. Enter before and after depths in inches, invoice and between-dip consumption in US gallons, and a reading tolerance.
3. Review the modeled interval and full calculation, save the check, and share its report if useful.

This is a paperwork review aid, not leak detection, proof of shortage, a safe-fill instruction or regulatory compliance. The interval varies depth readings independently; it is not statistical confidence. Tank fit, tilt, temperature, settling and uncertainty in consumption are excluded. Non-propane published charts only; up to 30 saved checks.

Adds Supplier Call Sheet, turning the current tank plan into a concise order brief with gallons on hand, suggested order size, estimated cost, order-by date, and delivery notes.

DeliveryLab: Invoice-versus-tank-rise checks, price history, burn context, and supplier packets.

- Identify tank geometry, calibration source, gauge type, and reading conditions
- Record before and after readings without overwriting either observation
- Compare geometry-estimated rise with invoice quantity and delivery notes
- Review price, degree-day, burn-rate, and timing context separately
- Export a neutral supplier packet with uncertainty and questions
