EWM Invoicing System — 4-step workflow with automatic and manual entry

Challenge

EWM processed 50+ invoices per day, all manually in Excel. Each invoice took 40 minutes. The AP team spent 2-3 hours daily on data entry alone with frequent errors in rates, hours, and totals.

Solution

We built a custom invoicing platform with unique worker links, two submission modes (automatic PDF extraction or manual entry), a 4-step guided workflow, and automated PDF generation with email delivery.
