AI that pays for itself: stopping out-of-policy, duplicate, and fraudulent spend before it happens

The hidden leaks draining your P&L

Every finance leader knows the pain of out-of-policy spend, duplicate invoices, and fraudulent charges that slip through the cracks. Even small mistakes add up. A single duplicate payment can offset the value of a finance system subscription for months, while unapproved spend causes audit headaches and compliance risks no one wants on their plate. These invisible leaks don’t just waste time — they quietly drain budgets, delay audits, and create financial blind spots, putting compliance and cash flow at risk.

The worst part? Finance teams often get cast as the “spend police,” catching issues after the fact and straining relationships with employees and managers. Instead of enabling the business, they’re forced into damage control.

Why traditional controls fail

The problem is that most controls are reactive. Post-facto reviews, manual approvals, and audits only flag issues after the money has left your account. By then, cash flow is disrupted, recoveries are uncertain, and compliance risks are staggering.

How AI turns cost centers into profit protectors

Most finance tools promise efficiency but few deliver measurable financial impact. Spend AI is different: it actively protects your P&L by stopping losses before they hit your books.

Here are some examples of what that might look like in practice:

• Duplicate protection in payables: Imagine a mid-market logistics company processing thousands of invoices. Without AI, a duplicate vendor invoice could easily slip through. With Spend AI, that invoice would be flagged before payment, preventing a six-figure overpayment.

• Policy enforcement in real time: Picture a global marketing team booking last-minute travel. Instead of discovering non-compliant flights weeks later during audit, the expenses agent flags them at expense submission, preventing budget leakage before it happens.

• Risk detection across transactions: Envision a retail chain where repeat charges appear on corporate cards. Traditional reviews might not catch it until month-end. AI-driven risk detection surfaces the issue immediately, avoiding potential fraudulent spend.

Even catching a single duplicate reimbursement or preventing one fraudulent charge could cover the cost of Spend AI for months. Multiplied across hundreds of transactions, the savings compound into hundreds of thousands annually.

From reactive to preventative finance

Most employees don’t read policy documents. As a result, they often don’t know the applicable limits, rules, or conditions around spending. Our data shows that 55% of out-of-policy spend flagged by Airwallex stems from simple lack of awareness, not malicious intent.

That gap creates unnecessary friction. Approvers are pulled into back-and-forth clarifications, finance teams spend time policing rather than partnering, and employees are left confused about what went wrong after the fact.

Preventative finance starts by closing that knowledge gap. Instead of expecting employees to memorise policies, Airwallex Spend embeds policy guidance directly into the moment of spend. AI evaluates transactions in real time, surfaces clear explanations when something is out of bounds, and helps employees course-correct before money is spent or submitted.

When prevented losses and eliminated manual reviews compound across hundreds of transactions, AI spend controls stop being a cost to justify and start paying for themselves.

For CFOs and finance teams, control without transparency is a nonstarter. Every AI action in Airwallex Spend is explainable and auditable, with humans kept in the loop for high-risk exceptions, so you stay in control, while AI handles the heavy lifting.
