Purchase Order Automation

Purchase order automation that runs on your purchasing rules.

We encode your purchasing rules — approvals, price checks, vendor terms — into AI agents that draft the PO and chase the acknowledgment.

  • AI implementation services
  • Your purchasing rules, encoded
  • POs drafted, dispatched, confirmed
  • Only exceptions reach a buyer

The broken Friday

The PO goes out. Then the chase begins.

From purchasing desks we have sat with: a PE-backed manufacturer running seven ERPs across its business units, where a purchase order still starts as an email or a hand-written form.

  • Requisitions on paper and email

    Parts of the business still hand-write requisitions; the rest email a spreadsheet. Nothing enters the ERP until a buyer reads it and keys the PO.

  • Approval by email ping

    Spend approvals move as email threads across business units — the PO waits in a drafts folder while someone chases the signature.

  • The acknowledgment chase

    The PO goes out by email; the vendor’s confirmation comes back to one buyer’s inbox, or doesn’t. Nobody knows what is confirmed and what is open.

  • Price checked against the last invoice

    Whether the vendor’s price matches the contract gets checked against memory or the last invoice — when it gets checked at all.

  • The rules live in one buyer’s head

    Each vendor’s quirks — minimums, lead times, the right contact for a shortage — live with the buyer who has always run that desk.

  • Seven ERPs, seven PO processes

    Each business unit keys POs its own way into its own ERP — the sponsor’s roll-up never sees a clean picture of open spend.

What manual costs

The purchase order is typed. Everything else is chased.

What the manual way looks like at a manufacturer whose requisitions arrive by email and paper, and whose purchasing rules live in buyers’ heads. Your numbers will differ — the first week puts figures on yours.

How it works

We encode your purchasing rules.

No purchasing platform for your team to adopt. The rules your best buyer carries become the check every PO passes.

  1. 01

    Shadow one purchasing desk

    We trace a week of POs from requisition to acknowledgment — reading, keying, chasing — and write down the rules only one buyer knows.

    Encode the purchasing rules

    Approval thresholds, contracted prices, vendor terms, per-business-unit logic — documented, encoded into agents, and deployed in your cloud environment.

    Yours to keep

    POs draft; buyers decide exceptions

    Each requisition is read against the rules and the PO drafted and dispatched; violations land in an exception queue a buyer decides.

    Every PO
Not another platform

The software sells you a license. Your purchasing rules are the product.

Purchasing software is a license plus a configuration project your team then maintains inside the vendor’s data model. The demo assumes one clean catalog; your business units run seven ERPs and a spreadsheet.

We are an AI implementation services firm: our AI reads each requisition against your encoded rules, drafts the PO, and routes only exceptions to a buyer — running in your cloud environment, yours to keep.
