# Online BL Printing Portal

> Customers print original Bills of Lading from their own office, with one-time passwords and admin-approved reprints.

- **Client:** Unifeeder
- **Industry:** Container logistics
- **Stack:** Electron, Angular, Spring Boot, Node.js, Oracle, AWS

## The problem

To get a Bill of Lading printed, customers had to visit the logistics partner's office in person.

Printing originals remotely needed control: who may print, on which printer, how often, and what happens when a printer jams halfway.

## What we built

- **Secure printing:** A one-time password by email or SMS before each print, and reprint requests that need admin approval.
- **Desktop app:** An installable Electron desktop app for printing, with features shown by role.
- **Customer onboarding:** Printing rights for several users per customer, with two-factor authentication.
- **Dashboards and reports:** Onboarded customers, print and reprint statistics, the last BL printed, and reports by customer and period.

## How it's built

An Electron and Angular desktop client, Spring Boot and Node.js services on AWS, and integration with the client's ERP to fetch the BL document.

## Results

- Customers print BLs from their own office instead of travelling to collect them.
- Every print and reprint is controlled and reported.
