Fraud-Fighter Profile: Vineet Grewal on relentlessly improving payment approval rates

Today we are talking about payment approval rates and what it really looks like when a fraud leader refuses to treat approvals as someone else’s metric.

I sat down with Vineet Grewal, Senior Manager of Risk at Wish, to talk about why improving payment approval rates has become her North Star and why the best fraud leaders know that stopping bad transactions is only part of the job. The other part is making sure good customers are not getting blocked by the very systems meant to protect the business.

Vineet has one of those rare combinations that always stands out to me in fraud. She can go deep on sophisticated fraud cases, think clearly about complex fraud risk stack decisions, and still stay focused on the broader business outcome. That matters because payment approval rates are not just a payment issue. They are a revenue issue, a customer experience issue, and absolutely a fraud leadership issue.

And that matters.

Because if your fraud program is reducing chargebacks while quietly increasing false declines, you are not really winning. You are just shifting where the damage shows up. This conversation gets into the real balance between fraud prevention and growth, and why stronger payment approval rates should be part of every serious fraud strategy.

What you’ll hear in this episode:

  • Why payment approval rates became Vineet’s North Star in fraud leadership
  • How authorization rate optimization requires end-to-end measurement, not just front-end review
  • Why fraud and approval balance matters more than simply reducing chargebacks
  • How marketplace fraud prevention changes across regions, payment methods, and customer behavior
  • Why fraud vendor accountability and cross-functional fraud storytelling are critical to improving results

You should listen to this episode if you:

  • Own fraud, payments, or risk and want to improve payment approval rates without compromising protection
  • Are focused on reducing false declines and strengthening ecommerce payment optimization
  • Work in marketplace fraud prevention and need a sharper approval rate strategy
  • Want a better framework for connecting fraud operations metrics to revenue outcomes
  • Care about payment fraud leadership, vendor accountability, and long-term revenue protection strategy

Episode notes & key takeaways

Why payment approval rates should be a fraud leadership metric

Let’s break this down.

One of the biggest takeaways from this conversation is that payment approval rates should never be treated as a side metric owned only by payments teams. Vineet makes the point clearly that fraud leaders need to care just as much about the good transactions they allow through as the bad ones they stop. That is what separates tactical fraud management from strategic fraud leadership.

Too often, teams celebrate lower chargebacks without asking what happened to legitimate customer approvals along the way. But reducing false declines is not a nice-to-have. It is one of the clearest ways to protect revenue, improve customer trust, and prove that fraud controls are actually supporting the business instead of slowing it down.

Here is what is actually changing:

  • Payment approval rates are becoming a more important measure of fraud program health
  • Reducing false declines is a core part of protecting revenue and customer trust
  • Fraud and approval balance matters more than optimizing for one metric alone
  • Chargeback reduction strategy should never come at the cost of legitimate sales

Why authorization rate optimization has to be measured end to end

Here’s what’s actually happening.

A lot of teams think they understand their approval performance because they are looking at the front end of the funnel. But as Vineet points out, payment authorization performance needs to be measured end to end. If you only look at one step in the process, you can miss where legitimate transactions are actually falling out.

That means fraud teams need to understand the full path from risk decisioning to issuer response, not just whether a transaction looked risky when it entered the system. Real authorization rate optimization comes from looking across the entire payment experience and identifying where friction is happening, whether that is inside your stack, with a vendor, or downstream with payment partners.

  • Authorization rate optimization requires visibility across the full transaction lifecycle
  • Front-end approval does not always equal final payment success
  • Fraud operations metrics should connect risk decisions to final authorization outcomes
  • Ecommerce payment optimization improves when teams stop measuring in silos

Why global context matters for marketplace fraud prevention

So much of fraud leadership comes down to understanding context, and this episode is a great reminder of that. Vineet talks about the importance of being aware of the variables that affect payment approval rates across different geographic markets, including holidays, consumer behavior, and payment method preferences.

That is such an important point. Because what looks suspicious in one market may be normal in another. A control that works well in one region may hurt approvals somewhere else. Global payment approval trends are shaped by local behavior, and marketplace fraud prevention gets a lot more effective when fraud teams build strategy around those differences instead of assuming one model fits everything.

  • Global payment approval trends vary by region, seasonality, and behavior
  • Marketplace fraud prevention requires local context, not just global rules
  • Payment method differences can affect both fraud risk and approval performance
  • Strong approval rate strategy depends on market-specific insight

Why fraud vendor accountability and storytelling improve results

This is the part I especially appreciated.

Vineet does not frame fraud leadership as just a technical exercise. She talks about the importance of holding vendors accountable and using data and storytelling to communicate with cross-functional teams. That is exactly right. Because improving payment approval rates usually requires alignment across fraud, payments, product, and operations, not just better models.

If a vendor is influencing your fraud risk stack, they should be able to explain their impact on approvals, declines, and fraud outcomes. And if you are trying to get buy-in internally, data alone is usually not enough. Cross-functional fraud storytelling matters because it helps other teams understand the tradeoffs, the customer impact, and the business value of making smarter decisions.

  • Fraud vendor accountability matters when approval performance is under pressure
  • Cross-functional fraud storytelling helps teams align on risk and revenue tradeoffs
  • Revenue protection strategy depends on both strong analysis and clear communication
  • Payment fraud leadership means influencing outcomes beyond the fraud team

The big takeaway from this episode is pretty straightforward. Payment approval rates are not secondary to fraud performance. They are part of fraud performance. The strongest fraud leaders know how to protect the business from bad actors without creating unnecessary barriers for good customers. That is the balance Vineet brings to this conversation, and it is exactly the kind of thinking more teams need.
