Why teams look for this

Finance teams often receive large numbers of supplier invoices by email

Open email attachment
Find invoice number, totals, VAT
Manually enter data into accounting software
Repeat

This process is repetitive, slow, and prone to errors.

You need your data to stay on your network - whether it's compliance, policy, or preference

What it does

INBOXextract automates data extraction directly from incoming emails

Monitors mailboxes
Extracts fields from email (including attachments)
Outputs structured data (CSV / API / spreadsheet)

Who it's for

Finance teams processing supplier invoices from shared inboxes
Businesses with data residency, compliance, or security constraints
Teams that want automation without black-box AI behavior

Privacy & control

Unlike most email parsing products, INBOXextract :

Runs entirely inside your company network
Deterministic extraction rules for predictable outputs
No AI = no hallucination risks
Emails are not sent to external services
