Invoice as a service

This service generates professional looking PDF invoices, from a simple POST HTTP request with json payload.

File destinations / storage

Rendered file can be returned into the HTTP response or exported to:

• AWS S3 (and any compatible storage destination)
• FTP server
• Webhook
• Zapier: "Catch hook" trigger, can be linked to Drive, Dropbox...

Demo

Usage

I provide invoice-as-a-service with a full hosted environment for fast and easy setup (endpoint: https://invoice-as-a-service.cleverapps.io).

For improved privacy, you can also deploy the project on your own infrastructure for free.
