What does AI in accounts payable actually look like right now?

Mostly data extraction and matching. AI invoice processing software pulls structured data out of invoices, statements and orders, whatever format they arrive in, and matches it against POs and goods receipts automatically. That's a different job from an AI agent that's been given open-ended access to build or run a system.

Does Open ECX use AI in its automation?

Yes. AI is part of how we extract and process data across invoices, orders and statements, whatever format they arrive in.

Is AI in accounts payable safe to use?

It depends entirely on what the AI is allowed to touch and who's accountable for it. Narrow, monitored AI doing data extraction is a different risk profile to an autonomous agent with broad system access and no oversight, which is exactly what OpenAI's own incident demonstrated.

Didn't OpenAI's own AI go rogue? Isn't that an argument against AI altogether?

Not quite. It's an argument against handing AI broad access with no accountability and no track record. That's exactly the setup with a homemade tool. It's exactly what we've spent years building against.

Can't I just build an AP automation tool myself with AI?

You can build something. The question is whether you'd trust it with your supplier bank details the same week OpenAI admitted it couldn't keep its own model inside a test environment.

What's the difference between AI in accounts payable and building your own AI tool?

Accountability. Open ECX's AI runs inside a platform with a dedicated team, a security track record and 17,000+ active trading parties already depending on it. A homemade tool has one person who understands it and no one else checking its work.

Even OpenAI's own AI went rogue. Make sure yours is secure.

We love AI. The question to ask is what that AI is plugged into, who's accountable for it, and what happens the day it goes wrong.

Here's the bit that should worry a finance team more than a tech team. If OpenAI can't keep its own model inside a locked test, what's your AI invoicing tool doing with the supplier bank details, the cash flow visibility and the audit trail your auditors are going to ask for? That's not a hypothetical version of the risk. It's the same category of AI, with none of the containment.

That's the bit worth sitting with before you file this under someone else's problem. OpenAI confirmed the incident directly on 21 July 2026, and Hugging Face published its own disclosure the same week, calling the campaign an example of the 'agentic attacker' scenario the industry has been forecasting for years. It isn't an isolated data point either: the UK's AI Security Institute has been tracking the same trend, independently finding that frontier models are getting measurably better at sustaining complex, multi-step cyberattacks over long time horizons.

"Why do I need Open ECX when I can build this myself?"

Fair question, but not one we hear from our customers a lot, because they know the value and security we bring. AI coding tools make it genuinely easy to knock up something that looks like an invoicing system over a weekend. Type a prompt, get a working prototype, feel like you've cracked it.

Here's what the OpenAI incident proves. Speed and autonomy are exactly what make these tools risky. Give an AI agent broad access and no one watching, and it will do a startling amount on its own, whether you asked it to or not. That's not a hypothetical anymore. It's what OpenAI just admitted happened to a company with far more security expertise than most finance departments have on tap.

We use AI too. It's partly how we pull accurate data out of invoices, statements and orders across every format your suppliers throw at us. The difference isn't AI versus no AI, and it isn't really about AI in accounts payable versus none at all either. It's what that AI is plugged into, who's accountable for it, and what happens the day it goes wrong.

Vibe-coded vs secure AI in Accounts Payable

A DIY AI tool, built fast, looks very different from AI in accounts payable built for the job:

DIY AI Tool	Open ECX
Financial data goes straight into a project nobody outside your building has stress-tested	A platform already processing documents for 17,000+ active trading parties
One person understands how it actually works, and they're not always available	A dedicated team who built it, maintain it and answer the phone when something needs fixing
When it breaks, or gets hacked, there's no support line to call	An accredited Peppol Access Point, so the plumbing behind the scenes is already recognised
It's been running for a weekend, not through years of real invoices	Years in production handling real financial data, not days in a prompt window
Nobody's checked whether the AI itself is secure, let alone what it's plugged into	AI built and run by a team who do this for a living, with security designed in from day one

‍

Both use AI. Only one has a team bigger than the person who built it.

Worth thinking about before April 2029

If the proposed April 2029 e-invoicing mandate lands as expected, more finance teams will feel pressure to automate fast. That's exactly the moment a homemade AI tool feels tempting. Quick, cheap, "good enough." It's also exactly the moment your invoice data can least afford a platform that hasn't been properly tested, by anyone, against anything.

You don't need to build this yourself, and you don't need to find out the hard way what happens when an AI agent gets more access than you intended. Whatever the mandate ends up requiring, we're already built to flex around it.
