Accounts Payable Outsourcing01

Accounts payable outsourcing, without the outsourcing.

We build AI agents that reconcile every invoice inside your systems, by your rules — you keep the team, the rules, and the IP.

The broken Friday01

The invoice fires never stop.

From an AP floor we have sat with: an interim CFO at a waste-services broker — 2,300 hauler vendors, 29,000 customer locations, every invoice keyed by hand — weighing outsourced capacity against a better answer.

  • Fighting invoice fires

    Duplicates from the email-plus-scan double channel, late payments straining hauler relationships, an inbox that never empties — every week is triage.

  • The PO was there — “not found, not truly missing”

    The purchase order exists; nobody can find it at keying time. The match fails, the exception queue grows, and the bill waits.

  • What did it cost me last year?

    A six-yard container, serviced twice weekly, costs one number this week. What it cost last year means pulling the actual invoice, line by line.

  • “Slapped with 40% inflation — and we don’t see it”

    Vendor price increases stay invisible unless someone goes and pulls the actual invoice. At line level, across 2,300 vendors, nobody does.

  • The vendor that consistently overbills

    Everyone suspects it; nobody holds the line-level pricing history to prove it, and the follow-up call on the material variance never happens.

What manual costs02

The manual way is a line item, not a feeling.

How it works03

Vendor payment automation that starts with your rules.

No new system, no outsourced floor. The rules your best AP person carries become the agents’ instructions — inside the systems you already run.

  1. 01

    Map the invoice rules

    We write down every rule a bill gets judged by — contract rates, surcharge tables, PO tolerances, what each service cost last year.

    Weeks 1–2
  2. 02

    Build the agents in your cloud

    AI agents read each invoice, find the PO that was there all along, and check every line against your rules — inside your ERP, in your cloud.

    Weeks 3–8
  3. 03

    Your team takes only exceptions

    Clean invoices pay themselves. A crept price, a duplicate, a missing rate lands in a review queue with the rule it broke — a person decides.

    Human in the loop
The build-or-outsource call

AP outsourcing moves the work to their floor. Encoding the rules keeps it on yours.

A BPO quotes seats and a 90-day ramp. The people learning your vendors sit on their floor, turn over, and take the knowledge with them when the contract ends.

We build AI agents that reconcile invoices inside your systems, against your encoded rules. The work stays with your team, the rules run in your cloud, and the IP stays yours.

Questions04

Asked by finance leaders weighing a BPO.

The straight answers, before you book anything.

Accounts payable outsourcing hands invoice processing to an outside firm: their people key, match, and approve your bills from their floor. The alternative keeps the work in-house without keeping it manual — AI agents reconcile every invoice inside your systems, against your encoded rules, and only exceptions reach your team.

When the problem is pure headcount on stable, low-judgment keying, a BPO can be fine. It fails when the value lives in your exceptions — contract rates, price creep, the PO that was there but not found. That judgment is exactly what should be encoded and kept, not rented.

Every invoice line is checked against the contract rate, the surcharge table, and what the same service cost last time — a continuous purchase price variance check on every bill, not a quarterly sampling. A vendor nudging rates up gets caught at the first invoice, flagged with the amount.

That is the normal case we start from. Legacy OCR reads one field in five on bills like these; the agents we run in production read 97–98%, because they read for meaning against your vendor dictionary, not for characters.

Then go straight to the detail pages: AP invoice automation covers reading and keying, two-way matching covers the PO match, invoice reconciliation covers the billing side. This page exists for one decision — whether the work leaves your house or the rules get encoded inside it.

You do. The rule set is documented and handed over, the agents run in your cloud, and anything we built keeps running. There is no lock-in designed into the work.
