Case studyNatural HeroesFinance & Back-Office

We built an AI invoice agent that reads their inbox and posts to the ledger. The admin team is half what it was.

A fast-growing CPG brand was hiring into AP every time revenue stepped up. We built an agent that reads inboxes, parses invoices, maps the right ledger codes, and posts them into the system — then layered on payment-due flagging and approval triage. Half the admin team, twenty-five hours back every week, two-day month-end close.

The setup

Natural Heroes was growing into the kind of operating shape that punishes growth. Volume climbed, and so did the invoices — supplier bills, marketing partners, 3PL receipts, recurring SaaS, ad-hoc cards. The admin team was sorting them by hand: pulling attachments from inboxes, typing line items into the accounting system, choosing ledger codes from memory, and chasing approvals over Slack.

It worked. It was also the wrong place to be hiring. Every new revenue dollar brought in more invoices, not more time. The next hire was going to be another set of hands on the same manual workflow.

What we built

We started in the one place every invoice already lived: email. We built an AP agent that watches the inboxes the team uses for vendor mail. When an invoice arrives, the agent identifies the message type, pulls and parses the attachment, matches the vendor against the existing supplier record, picks the correct ledger codes from the patterns the team had already established, and posts the entry into the accounting system ready for approval.

Then we layered the next tier on top. The agent now also flags invoices that are coming due, surfaces ones that fall outside historical norms — price, vendor, line items — and routes approvals to the right person without anyone copy-pasting context into Slack.

Nothing leaves the company without a human still saying yes. The agent does the work that should never have been manual. The team does the work that always should have been theirs.

What changed

The AP function is now half the size it used to be. The people who stayed are no longer doing data entry — they are doing what AP was supposed to be: catching the things that should not happen and approving the things that should.

Month-end close went from more than a week to two days. Roughly twenty-five hours each week are no longer spent handling invoices by hand. None of this happened on the first try — there were edge cases the agent learned over the first few weeks, and a handful of vendor formats that needed a second pass. The team caught most of them before we did.

Where it goes from here

The same agent now handles statement reconciliation and quarterly close prep, with vendor onboarding next on the roadmap. The pattern keeps compounding because the team is no longer the bottleneck — they review what the agent surfaces and decide what runs.

That is the only way an AP function scales without growing.
