BigCommerce merchants now have access to the full Wyllo platform through a native integration on the BigCommerce App Marketplace. Wyllo, the CX-first risk intelligence platform built from the combination of NoFraud and Yofi, helps BigCommerce brands stop fraud, refund abuse, account takeover, and chargeback losses upstream without adding friction to the customers who matter most.
This page explains how the integration works, what BigCommerce merchants typically see when they deploy Wyllo, and how to get started.
Why BigCommerce Merchants Choose Wyllo
The pattern that brings most BigCommerce merchants to Wyllo is the same one shaping ecommerce broadly: rules-based legacy fraud tools have started to cost them more in false declines and missed abuse than they save in caught fraud. The patterns moved. The tooling didn’t. The result is over-blocked good customers and post-purchase abuse the transaction screen never sees.
Wyllo addresses that head-on with four capabilities that consistently come up in customer conversations:
Higher approval rates on real customers. Wyllo Payment Fraud Protection pairs AI-driven decisioning with human fraud experts who validate the orders worth a second look. The merchants seeing the strongest approval rates use both layers together. Pure-AI systems tend to over-decline borderline orders (foreign cards, high-value first-time buyers, mobile orders from unfamiliar locations). The human-expert layer is what recovers them.
Connected signal across the journey. Most legacy tools score one transaction at a time. Wyllo connects identity, device, behavioral, and merchant-specific signals across checkout, returns, claims, support, and account behavior. That’s where the most damaging abuse patterns live, and it’s where they become visible.
Embedded inside the workflows BigCommerce teams already use. Risk scores and recommended actions show up where decisions are made, not in another dashboard nobody opens. CX, ops, and finance get the context they need in the moment they need it.
Optional chargeback guarantee for predictable economics. For merchants who want the residual loss converted into a fixed line item, the chargeback guarantee in Wyllo Payment Fraud Protection makes the math predictable.
What BigCommerce Merchants Are Saying
There’s no way a salesman who is growing a business by 20% a year should be tied to order reviews. When Wyllo came along, everyone was able to breathe a sigh of relief. It has taken the pain away from us.
— Josh Crawley, Sales Manager, TruTech Tools
Note: Wyllo is the rebrand of NoFraud and Yofi. Same team, same platform, evolved. Some customer reviews still reference NoFraud by name.
The pattern in this review shows up consistently. Risk decisioning, done well, is invisible. The right orders get approved. The risky ones get the right level of scrutiny. The rest of the business stops spending its time cleaning up after a fraud workflow that wasn’t quite working.
The Full Wyllo Platform for BigCommerce Merchants
Six products work together as one platform on BigCommerce. Pick the ones that map to your most painful surfaces; layer the others as you scale.
- Bot and Reseller Detection stops bots and unauthorized resellers from exploiting discounts, depleting inventory, and ruining the customer experience.
- Payment Fraud Protection uses AI fraud screening backed by human experts, with optional chargeback guarantee.
- Return Fraud and Abuse Prevention uses advanced risk models to enable personalized return policies right-sized to each shopper.
- Claim and Policy Abuse Prevention catches account takeover, refund manipulation, and policy exploitation upstream, before they cascade into chargebacks.
- CX Support embeds risk scores and next-best actions directly inside the CX tools your team already uses.
- Chargeback Management turns representment into an AI-driven workflow that wins more disputes with less manual case-building.
How the BigCommerce Integration Works
The native Wyllo app on the BigCommerce App Marketplace installs in minutes. Once connected, Wyllo screens orders in real time, with no manual integration work required on the merchant side.
A typical deployment runs roughly as follows:
- Install the Wyllo app from the BigCommerce App Marketplace.
- Connect your store and select the products you want to enable (Payment Fraud Protection at minimum; others can be layered in).
- Configure your decisioning preferences in the Wyllo console. The Wyllo team helps tune to your specific risk patterns, payment mix, and customer base.
- Start screening orders. Most BigCommerce merchants see results within the first billing cycle, including higher approval rates on borderline orders and lower manual review time.
For merchants who want a deeper conversation about which products fit their specific business, the Wyllo platform overview page and the Wyllo partners page are both good starting points.
Frequently Asked Questions
Does Wyllo integrate with BigCommerce?
Yes. The Wyllo app is available on the BigCommerce App Marketplace as a native integration. Most BigCommerce merchants are up and running within minutes of installation.
What does Wyllo do for BigCommerce merchants?
Wyllo handles the full risk intelligence layer for BigCommerce stores: fraud screening at checkout, return and refund abuse prevention, account takeover and policy abuse detection, bot and reseller defense, embedded decisioning inside CX and support tools, and chargeback management. Merchants pick the products that map to their most painful surfaces and add more as they scale.
Is the Wyllo app free?
Pricing depends on the products and volume. The BigCommerce App Marketplace listing handles install and trial setup; pricing conversations typically happen with the Wyllo team during onboarding. See the BigCommerce app listing or contact the Wyllo team for current options.
How is Wyllo different from rules-based fraud tools?
Two material differences. First, Wyllo pairs AI-driven decisioning with human fraud experts who review the orders where merchant-specific context matters most. The result is higher approval rates on real customers without sacrificing fraud catch rates. Second, Wyllo connects signals across the full customer journey (checkout, returns, claims, account behavior, support) rather than evaluating one transaction at a time. The patterns that hurt BigCommerce merchants most (coordinated abuse, friendly fraud cascades, refund manipulation) live in those cross-surface connections.
Does Wyllo offer a chargeback guarantee?
Yes, optionally. Wyllo Payment Fraud Protection includes an optional chargeback guarantee that converts the residual fraud loss into a predictable line item.
How long does implementation take?
The BigCommerce app installs in minutes. Configuration and tuning to your specific patterns typically happens during the first onboarding conversation with the Wyllo team. Most merchants see measurable results within the first billing cycle.
