Magnolia turns tank geometry, vendor quotes, or engineering data into a complete, itemized bid — and prints a line-by-line calculation receipt for every number. Deterministic, auditable, and covered by 1,000 automated tests.
A guided walkthrough of the product, the three estimating modes, and what's included in the sale.
Most bids for large field-erected tanks are built in sprawling private spreadsheets — hard to audit, easy to break, and tied to one or two people. Magnolia applies one consistent, calibrated methodology to every estimate, separates the calculation engine from the interface, and exposes the full calculation trail so any figure can be inspected and explained. It runs as a self-contained browser application on a single machine, with no external services or database required.
Prices a fast estimate from tank geometry alone, using the calibrated productivity, labor, equipment, and freight models.
Layers vendor and subcontractor quotes, crew and equipment selection, and the full financial stack — overhead, SG&A, contingency, and profit — on top of the geometry baseline.
Prices directly from a tank's engineering bill of materials and weld report, injecting real weights and weld productivity and pinning each value to its source.
Each value shows its label, formula, inputs, and result — a line-by-line receipt a reviewer can follow end to end.
The same inputs produce the same priced estimate every time, from a shared calculation library independent of the browser.
The final sell price stays blank until the estimate contains everything needed to price it — and a confidence indicator flags internal inconsistencies.
Overhead absorption, SG&A, contingency, and profit assemble on top of the technical estimate, with profit-scenario views.
Productivity, labor, equipment, and financial models are tuned against anonymized outcomes from completed projects.
One workflow prices new construction, repair, or demolish-and-rebuild work, with print-friendly HTML and CSV export.
Real screens from the packaged demo — a 120' × 48' cone-roof tank priced in Budget mode. Every figure is synthetic; no real customer, project, or pricing data is shown.
Magnolia is offered as a complete v1.0.0 commercial release — full source code, tests, and documentation. A confidential buyer package is available to serious prospective acquirers.
