Ever since Shopify started changing the way the world builds ecommerce businesses, Signifyd has been protecting the merchants building on it. From the earliest days of Shopify Plus to today’s ecosystem of hundreds of thousands of stores, our partnership has grown along with the platform. We’re a preferred vendor for Shopify Plus, a partner Shopify recommends directly and one of the few fraud protection providers built to serve every stage of a Shopify business, from founders just launching to global brands processing billions in GMV.
That heritage matters, because fraud protection isn’t a feature you bolt on. It’s a long-term relationship with a partner who understands your platform, your growth trajectory and your customers. Here’s why so many Shopify merchants choose Signifyd, and what makes that partnership work.
TL;DR
- Signifyd is a long-standing Shopify Plus preferred partner, built to protect merchants of every size, not just enterprise.
- Our guarantee covers every card-not-present chargeback and dispute across all payment methods, including return abuse, item-not-received (INR) claims and promo/reseller abuse.
- Our full-journey coverage also keeps merchants under Visa’s new 1.5% VAMP threshold, no extra compliance dashboard needed.
- Dispute management is fully handled by our team, and every decision is explainable, backed by AI paired with human review.
- Merchants like Carbon38, Cuts, Rainbow Shops, Cymbiotika, Au Vodka and Mack’s Prairie Wings see approval rates above 98% with sharp drops in chargebacks and fraud losses.
Built for every merchant, not just the biggest ones
Many fraud solutions in the Shopify ecosystem are designed only for the largest enterprise brands. That works fine if you’re running nine figures in GMV. It works less well if you’re an emerging brand trying to scale past your first million in sales, or a mid-market retailer expanding into new markets.
Signifyd protects merchants at every stage of growth. We built our Commerce Protection Platform to grow with a merchant from their first sale to their billionth, so you never have to switch fraud partners as you scale.
Staying under Visa’s new VAMP threshold, without another dashboard to manage
Some fraud providers require another dashboard to manage the new, tighter threshold of the Visa Acquirer Monitoring Program (VAMP), reduced from 2.2% to 1.5% for merchants, which can lead to higher costs, tighter card acceptance and a harder conversation with their acquirer.
Rather than requiring monitoring of the new 1.5% dispute ratio, Signifyd’s guarantee covers every card-not-present (CNP) chargeback and non-fraud dispute across every payment method a Shopify store accepts, and our decisioning already spans the full customer journey. Keeping a merchant’s VAMP ratio healthy isn’t a bolt-on feature. Instead, it’s a byproduct of stopping illegitimate disputes before they’re ever counted.
Guaranteed protection across the full customer journey, not just at checkout
A lot of fraud conversations start and end at chargebacks. Ours doesn’t. Signifyd protects the entire customer journey — from account creation and login to purchase, post-purchase disputes and returns.
Signifyd’s abuse decisioning engine provides measurable results. For example, BHFO used Signifyd to eliminate false positives on genuine orders while cutting chargebacks 69%, and turned return abuse mitigation into a 1.6% revenue recovery. In a separate case study, a $15 billion omnichannel retailer had shut off its instant refunds program entirely because return fraud had climbed to 510 basis points of total volume. After adopting Signifyd’s risk-based approach, they cut fraudulent returns by 75% and brought the program back without reopening the losses. These case studies highlight the vital value of protecting the entire customer journey.
AI that merchants and their teams can actually trust
Every fraud provider will use AI. What matters is whether that AI comes with real accountability — what the industry calls explainable AI. Signifyd combines machine learning, trained on a commerce network of 950 million identities across thousands of merchants, with human fraud experts who review edge cases and refine outcomes. That combination provides clearly explainable decisions and drives our dispute win rates past 50%. Merchants should always be able to understand why an order was approved or declined, especially when it’s their revenue on the line.
Proof, not promises: Customer testimonials
Shopify merchants across nearly every category rely on Signifyd today, and the results speak for themselves.
Mack’s Prairie Wings, a specialty outdoor retailer, automated 100% of its online order review and lifted approval rates by nearly 6%, proof that this isn’t only an enterprise story.
Carbon38 automated 100% of order review and achieved a 99% approval rate, freeing its team to focus on customer experience instead of manual fraud review.
Cuts Clothing eliminated fraud and item-not-received chargeback losses entirely, pushed approval rates above 99% and saw 122% ROI within six months, unlocking expansion into new international markets.
Rainbow Shops reduced chargebacks, lifted its dispute win rate to 51% and maintained a 99.5% approval rate after moving to Signifyd’s native Shopify integration.
★★★★★ “We’ve been using Signifyd for about four years, and it’s been a game-changer. The platform provides reliable, intelligent fraud protection, and their support team is always quick and helpful. Since using Signifyd, we’ve seen higher approval rates and fewer chargebacks. Highly recommend it to any Shopify merchant!”
Cymbiotika grew its approval rate to 98% and cut chargebacks by 93%, even as subscription order volume climbed.
Au Vodka cut fraudulent orders by 97%, paid $0 in fraudulent chargebacks and grew year-over-year sales by 133% while expanding across Europe.
And it’s not just the numbers. As Lyn Carbine, head of trading at Current Body, put it:
“Since we became Signifyd customers, our business has expanded into the Netherlands, Sweden and Denmark. With Signifyd, there was not even a learning period in these regions. Typically, you would expect to see a dip in approval rates, but we were able to hit the ground running. We maintained an above 98% approval rate from day one in all three.”
Across our merchant base, Signifyd has protected more than $10.9 billion in GMV over the past year alone. And our network recognizes identities behind 98% of online purchases, giving every Shopify merchant the benefit of pattern recognition built from thousands of stores, not just their own order history.

Common questions
Does Signifyd cover chargebacks on every payment method, or just Shop Pay?
Signifyd’s financial guarantee covers card-not-present chargebacks and non-fraud disputes across every payment method a Shopify store accepts, not a single checkout flow.
How does Signifyd rank among consumer reviews?
On the Shopify App Store, Signifyd holds 4.6 out of 5 stars across 84 reviews. Signifyd is consistently praised for being highly responsive, providing complete peace of mind and being held to high standards.
Is Signifyd built exclusively for large Shopify Plus enterprises?
No. Signifyd’s Commerce Protection Platform is built to scale from a founder’s first hundred orders to a global brand’s billionth, so merchants don’t have to switch fraud partners as they grow.
How does Signifyd help merchants stay under Visa’s VAMP threshold?
Visa lowered its merchant VAMP threshold to 1.50% on April 1, 2026. Signifyd’s guarantee already covers disputes across the full customer journey, meaning fewer illegitimate disputes affect a merchant’s fraud and dispute ratio in the first place, eliminating the need to add a separate compliance dashboard on top.
Who handles chargeback disputes, the merchant or the provider?
Signifyd’s dispute management is fully handled by Signifyd’s fraud experts, who prepare and submit evidence for each bank’s requirements. Some competing tools instead give merchants a dashboard and template editor to prepare and submit their own evidence.
Does Signifyd protect against more than payment fraud, like returns and policy abuse?
Yes. Our abuse decisioning engine covers reseller abuse, promo abuse and account takeover, and Intelligent Returns scores return risk in real time so merchants can safely offer instant refunds.
