Track SaaS spend from email invoices with AgentMail, JigsawStack and Postgres

WHAT you need

1. Jigsaw API key for image processing, I use this as a gatekeeper/second pair of eyes.
2. LINK to their website
   https://jigsawstack.com/
3. SECOND A postgress DATABASE (I use Supabase)
4. LlamaCloud for the parsing (you can replace this with Jigsaw if you like)
5. Redis (Optional , but I would strongly advise using it)
6. agentMail , this is your trigger email adress and BOX
7. Webhook Trigger (Svix or n8n's builtin webhook)

WHAT is it?

This is an easy way to track your SaaS spending, especially for small business owners or solopreneurs. It's essentially exactly what tools like Spendbase and Ramp do, without the virtual card.

HOW it works

After getting your API keys, all you need to do is set up an AgentMail inbox for your invoices. This is your trigger.

In the current setup, the workflow will only trigger if you send an attachment.

You can find more information on how to use the workflow in the workflow notes.

The database schema

You can find it as a deactivated code node in the workflow.
