Invoice ingestion

Bring new Linde invoices into one clean inbox.

Sign in to Linde in the same browser you use for this app. The Ranger Gas Co. browser helper finds only invoices prefixed with RI (purchased) or GC (cylinder rental and tracking), reads the invoice detail, and sends only structured invoice data back for import.

Connect, scan, import

Ready

1
Import new invoices
Click once to open Linde in a new tab. Sign in there if needed; this page will detect authentication and automatically scan every invoice-history page.
2
Review the import
Only new RI and GC invoice numbers are added. Re-running a scan updates the same invoice instead of creating duplicates.
Nothing imported in this session.

The browser helper keeps your Linde credentials in the browser. The app receives only structured invoice data; it never receives your password.

Business Rules

These rules drive ingestion, mapping, period comparisons, cumulative roll-forward, and review status. The list is generated from the app’s rule registry so new rules can be added with the logic that uses them.
