If you’ve ever wasted time chasing down the right contract to verify an invoice, you know the drill: open a PDF, cross-reference line items, double-check terms, ping a teammate to confirm, and maybe–finally–pay the bill.
That’s just one invoice.
Now multiply that by every vendor, every month.
For accounting teams, this manual loop becomes a full-time job. Especially in orgs with heavy software spend, where nothing ships in a box and validating what you’re paying for requires detective work.
That’s why we built AI Invoice Match.
It’s a smarter, faster way to verify invoices, without the need for a traditional PO process. No extra tools or heavy setup. Just clean, automatic matching that saves time and cuts risk.

What is AI Invoice Match and how does it work?
In short: it’s your new best friend for invoice validation. AI Invoice Match:
- Automatically matches invoices to contracts
- Flags any discrepancies in seconds
- Saves your team hours of manual work each month
- Adds a layer of fraud protection, without adding friction
Under the hood, it works like this:
- Forward your invoices: Each company gets a unique Tropic forwarding address (like ap@yourcompany.tropicapp.io). Send invoices there—manually or automatically via inbox rules.
- Tropic scans and extracts: Tropic AI reads each invoice and pulls out key details: line items, billing terms, totals, dates.
- We match it to the right contract: Tropic connects the invoice to its source, whether that’s a signed contract, a vendor request, or both.
- Discrepancies get flagged: If something looks off - wrong amount, duplicate invoice, shady terms - we flag it. No more guesswork or Slack chases.
- Fraud protection: We check invoices against your known suppliers and contracts to catch anything that doesn’t belong.

Why invoice validation feels broken (because it kind of is)
POs have long been the default way to enforce control in finance. They make sense in a world of physical goods when you need to match what was ordered with what actually arrived.
But most growing companies today don’t run on parts and pallets. They run on contracts, SaaS licenses, and software subscriptions.
And yet…the PO system still sticks around, often duplicating what’s already written in a signed agreement. One contract turns into two artifacts, and teams end up updating both just to stay in sync. It’s time-consuming, and it rarely feels worth it.
We hear it over and over from our customers:
“We’re spending a ton of time manually validating invoices. Asking ourselves is this the right supplier? Are the terms accurate? Did someone approve this? All while trying to close the books on time.”
You shouldn’t need a giant PO process to feel confident about what you’re paying for. With AI Invoice Match, you can still have the audit trail, the checks and balances, the traceability, just without all the red tape and the extreme time suck.
AI Invoice Match flips that equation by letting the system do the matching for you
This is especially helpful for companies that are growing fast. Standing up a PO system across departments takes time, training, and constant upkeep. Tropic gives you a smarter, lighter-weight alternative that grows with you. Not just faster. Safer, too.
One of the biggest reasons we prioritized building this feature now is simple: fraud is getting worse.
According to a Medius survey, invoice fraud now costs the average company $133,000 per incident—and $1.2 million each year. Generating fake invoices is one of the easiest ways for bad actors to exploit overworked teams. And when your AP team is buried, it’s all too easy for something to slip through the cracks.
AI Invoice Match adds a layer of protection. If an invoice doesn’t match a known contract or approved supplier, Tropic will flag it before it ever hits your payment queue. It’s a small step that can prevent a very big mistake.

Built for real teams with real work to do
We developed AI Invoice Match with finance and accounting teams in mind, teams that are tired, burnt out, and don’t want to have to Slack another person to determine if this invoice is valid. Here's what’s going to change for you:
- You stop wasting time chasing documents
- You close the books faster every month
- You catch fraud before it costs you
- You get to focus on more strategic work, instead of validation
But this is also a big win for procurement, ops, and anyone else involved in spend management. By making the connection between contracts and invoices automatic, we’re reducing friction across the board and giving people back hours of time they used to spend playing document detective.
