For most finance teams, invoice intake still runs on a shared inbox. Vendors email a PDF, someone opens it, types the numbers into the accounting system, files the attachment, and marks the email as read. It works until volume grows — then context gets lost, invoices slip, and month-end becomes archaeology.
The shape of the problem
The work is repetitive but not trivial. Invoices arrive at different addresses, from many vendors, in inconsistent formats. The valuable part — the structured data and the file — is trapped inside an email. Automating intake means reliably extracting both and handing them to the system of record.
A simple pipeline
- Dedicated address. Route
invoices@(and a catch-all for variants) to a single inbound flow. - Parse and extract. Each message becomes a JSON object with sender, subject, and the attached PDF extracted and scanned.
- Match a rule. A routing rule like
invoices-to-erpfires a signed webhook to your accounting integration. - Log everything. Every message and delivery is recorded, so you can prove what arrived and where it went.

Why audit logs matter here
Finance lives and dies by traceability. When an invoice is queried weeks later, "it was in someone's inbox" is not an answer. A complete, exportable record of what was received, which rule matched, and where it was forwarded turns inbound email into a system you can actually audit.
The goal is not to remove people from the loop — it is to remove re-keying, lost context, and silent drops.
The takeaway
Invoice intake is a perfect first automation: high volume, clear rules, and an obvious payoff. Point a dedicated address at an inbound flow, route to your ERP, and keep the audit trail — then move on to the next email-driven workflow.
