Signifyd vs. Riskified on Shopify: Which Fraud Guarantee Wins?
Signifyd or Riskified depends on your dispute rate and where you sell. Past roughly 0.3% disputed orders, Signifyd is the Shopify-referenced default: free to install, a quote-based guarantee billed separately, and a 14-day trial (verified Sep 2026). Riskified competes through an enterprise sales process; its listing shows 4.8★ on 33 reviews and no price (verified Sep 2026). Below the line, Shopify Protect covers fraud chargebacks on eligible US Shop Pay orders free.
Your profile — see how the verdict shifts
- Confidence
- Medium — Both guarantees are quote-based and billed outside the Shopify invoice (verified Sep 2026), so the head-to-head is decided on install base, trial terms and procurement shape rather than price; Shopify Protect's scope is verified and narrow, which makes the native lane's boundary measurable in your own dispute data
- Reference scenario
- $20M–$100M GMV · 0.2–0.5% disputed orders · Shopify Payments · US-heavy · single storefront

Decision at a Glance
| Your profile | Verdict | Why |
|---|---|---|
| Under ~0.3% disputes, US store, most orders through Shop Pay | WAIT | Shopify Protect covers the total order cost and chargeback fee on protected fraud-based chargebacks for eligible Shop Pay orders, free, when you ship with tracking within seven days via an approved carrier (verified Sep 2026). Native fraud analysis plus Flow holds handle the rest. |
| Under ~0.3% disputes, non-US store or low Shop Pay share | CUSTOMIZE | Shopify Protect applies to US stores only (verified Sep 2026), so the free layer is thin here. A Flow rule-pack on native risk signals, a verification step and a small review queue cost $8,000–$18,000 (Deploi estimate, illustrative) and beat paying a guarantee on every good order. |
| 0.3%–0.9% disputes, $20M–$100M, single storefront | BUY | Signifyd: the category's most-referenced Shopify install base, free to install with a quote-based guarantee billed separately and a 14-day trial (verified Sep 2026). Run the trial against your decline log and price the fee against losses plus review labor before signing. |
| Enterprise scale: international mix, multi-storefront, procurement-led | DEPENDS | Run Signifyd and Riskified through one RFP on your own dispute history. Riskified's listing is free to install with external charges billed separately and shows 4.8★ on 33 reviews (verified Sep 2026); neither vendor publishes a price, so coverage terms and approval-rate commitments decide it. |
What Signifyd vs. Riskified Actually Drives
| Outcome | Impact | How it works |
|---|---|---|
| Revenue — direct | High | Approval lift is the sleeper win: network-scale decisioning approves borderline orders a manual reviewer would refuse, and each one is revenue you'd otherwise have declined; verify it against your decline log. |
| Operational efficiency | High | A guarantee retires the daily review hour and the dispute-response grind; the native lane keeps both, which is its real recurring price. |
| Customer experience | Medium | False declines are the fraud stack's customer-facing failure: a good repeat buyer refused with no explanation rarely returns, whichever lane produced the decision. |
| Data & insight | Medium | Dispute history, decline reasons and risk signals are negotiating leverage at every renewal; a vendor's black box keeps the reasons, while native tags and Flow logs keep them on your orders. |
| Retention & LTV | Low | Fraud tooling protects margin more than loyalty; the retention effect runs through fewer false declines and fewer shipment holds on good customers. |
Spend ceiling: Price the guarantee against three lines you can measure: fraud losses outside Shopify Protect's scope, review labor, and provable false-decline revenue. Below roughly 0.3% disputed orders the fee usually exceeds all three; above it, the guarantee also caps the tail risk (Deploi estimate, illustrative).
What buying enables (top apps)
- + Approved-order fraud losses moved to the vendor's balance sheet across every payment method, not only Shop Pay
- + Network-scale decisioning that sees card-testing patterns across thousands of stores before they reach yours
- + The daily review hour and dispute-response grind retired from your team
- + Signifyd: a 14-day trial to measure approval lift before any contract (verified Sep 2026)
What building additionally unlocks
- + Free coverage of fraud-based chargebacks on eligible US Shop Pay orders through Shopify Protect (verified Sep 2026)
- + Decline policy, verification scripts and review playbook in your brand's voice and under your control
- + Risk signals, tags and dispute history kept on your own order records as leverage for any future quote
- + Zero fee on every good order for stores whose dispute rate never earns a guarantee
Find Your Verdict in 3 Questions
Are disputed orders under roughly 0.3% of your orders on a rolling quarter?
Yes: Go to question 2.
No: Go to question 3.
Is your store US-based on Shopify Payments, with most orders paid through Shop Pay?
Yes: Your verdict: WAIT — Shopify Protect covers fraud-based chargebacks on eligible Shop Pay orders free when you ship with tracking within seven days (verified Sep 2026); add Flow holds for everything else.
No: Your verdict: CUSTOMIZE — native fraud analysis plus a Flow rule-pack, a verification step and a small review queue, $8,000–$18,000 (Deploi estimate, illustrative); Protect doesn't reach non-US stores.
Is fraud pressure enterprise-scale: international mix, several storefronts, procurement-led buying?
Yes: Your verdict: DEPENDS — run Signifyd and Riskified through one RFP on your decline log; both are quote-based and billed outside Shopify (verified Sep 2026), so negotiate coverage terms, not just the rate.
No: Your verdict: BUY (Signifyd) — the Shopify-referenced default with a 14-day trial (verified Sep 2026); measure approval lift and reimbursed disputes during the trial before the contract.
The TCC Scorecard — 12 Dimensions
TCC — Total Cost of Capability: what it actually costs to have this capability over three years, whichever way you get it. Each dimension is scored 0–5 for both paths. How we score →
| Dimension | Buy | Build | Why |
|---|---|---|---|
| Cost | |||
| Acquisition & implementation | Either guarantee integrates in days from a free-to-install listing, with rules alignment ($0–$10,000, Deploi estimate, illustrative); the Flow rule-pack, verification flow and review playbook take 2–4 weeks (Deploi estimate, illustrative). | ||
| Recurring fees | Both guarantees are quote-based and billed outside your Shopify invoice (verified Sep 2026), scaling with screened volume. Shopify Protect is free where eligible; the native lane's recurring line is review labor plus the fraud losses you retain. | ||
| Maintenance & upgrades | The vendor retunes its models continuously; your Flow rule-pack decays as fraud shifts and needs quarterly retuning, roughly 15–20% of build cost per year (Deploi estimate). | ||
| Switching & exit | Guarantee exits are operationally light but financially abrupt: fraud losses return to you the day coverage ends. Flow rules, order tags and dispute templates stay yours, and adding a vendor later is an integration, not a migration. | ||
| Risk | |||
| Vendor risk | Signifyd carries the most-referenced Shopify install base and Riskified a 4.8★ listing on 33 reviews (verified Sep 2026); both are established enterprise vendors. Native fraud analysis and Protect are Shopify's own. | ||
| Security & compliance surface | Order, device and customer data flow to the guarantee vendor for decisioning under enterprise-grade terms; the native lane keeps that data inside Shopify but leaves the loss liability with you. | ||
| Platform-deprecation exposure | Vendors absorb Shopify API changes; native fraud analysis, Shopify Protect and Flow are first-party surfaces with no deprecation exposure of your own. | ||
| Value | |||
| Fit to requirement | A guarantee moves approved-order fraud to the vendor's balance sheet across every payment method; Shopify Protect covers only fraud-based chargebacks on eligible US Shop Pay orders, and Flow rules cover no losses at all. | ||
| Time to market | Days for either guarantee, with Signifyd's 14-day trial (verified Sep 2026) as the measurement window; 2–4 weeks for the rule-pack and playbook (Deploi estimate, illustrative). | ||
| Performance & scale | Network-scale decisioning sees a stolen card tested across thousands of stores before it reaches yours; a manual review queue buries itself in a card-testing weekend. | ||
| Data ownership & AI-readiness | Decision reasons live in a rented black box, and false declines are uninsured and unlogged unless you audit them; the native lane keeps risk signals, tags and dispute history on your order records. | ||
| Focus & opportunity cost | Buying the guarantee removes a daily review hour and a P&L tail risk; the customize lane spends that hour every day, which is the real price below the 0.3% line. | ||
The App Landscape
| App | Status | Pricing | Best for |
|---|---|---|---|
| Signifyd | Live — The category's best-known guarantee name, with the most-referenced Shopify install base | Free to install; quote-based, usage-priced guarantee billed separately by Signifyd; 14-day trial at entry volumes; scales with volume (verified Sep 2026) | Mid-market stores past roughly 0.3% disputes that want the full chargeback guarantee with a trial to measure approval lift |
| Riskified | Live — flagged — 4.8★, 33 reviews; not Built for Shopify; pricing not listed. An enterprise chargeback-guarantee platform bought through a sales process, with external charges billed by Riskified separately from your Shopify invoice | Free to install; additional charges may apply; external charges billed by Riskified separately from your Shopify invoice; no plan names or figures published (verified Sep 2026) | Enterprise-scale programs where procurement runs an RFP and coverage terms are negotiated line by line |
| Shopify Protect + native fraud analysis | Native — First-party: free protection against fraud-based chargebacks on eligible Shop Pay transactions for US stores on Shopify Payments, when orders ship with tracking within seven days via an approved carrier; non-delivery, defect, damage and misrepresentation disputes are excluded | Free for eligible Shop Pay transactions (verified Sep 2026) | US stores with a high Shop Pay share and disputes under roughly 0.3% of orders |
| Flow rule-pack + review ops | Build lane — The customize lane for orders Protect leaves uncovered: Flow holds on native fraud analysis signals, a verification step for borderline orders, and a written review and dispute playbook | $8,000–$18,000 one-time plus review labor (Deploi estimate, illustrative) | Stores below the 0.3% line that Protect doesn't reach: non-US, or low Shop Pay share |
The Build Path
- Shopify Protect, made eligible: Turn on Shopify Payments and Shop Pay, ship every order with a tracking number within seven days via an approved carrier, and protected fraud-based chargebacks are covered at no cost, US stores only (verified Sep 2026).
- Flow rule-pack on native fraud analysis: Flow reads the native risk level and order signals: auto-hold high-risk orders before fulfillment, tag and route medium-risk to review, let the rest ship. Cancel-and-restock closes the loop on confirmed fraud.
- Verification step for borderline orders: A templated email or SMS asking the customer to confirm before you ship converts maybes instead of declining them; your brand's voice, not a vendor's refusal screen.
- Review ops + dispute hygiene: A written review SLA keyed to your fulfillment cutoff, plus dispute-response templates built from evidence Shopify already stores: order details, device data, delivery confirmation.
- Effort band
- $8,000–$18,000 for the rule-pack, verification flow and review playbook (Deploi estimate, illustrative); lands in the $10–25K contact-form band. Shopify Protect itself costs nothing (included where eligible)
- Typical timeline
- 2–4 weeks for the rule-pack and playbook (Deploi estimate, illustrative); either guarantee integrates in days
- Maintenance, honestly
- ~15–20% of build cost per year, roughly $1,500–$3,500/yr (Deploi estimate, illustrative): quarterly rule retuning as fraud patterns shift, Flow checks at API version bumps, and dispute-template refreshes. Review labor is the real recurring line, and it scales with order volume.
- What you own — and what you take on
- You own: the rules, the risk signals on your order records, the verification scripts and the dispute playbook. You take on: the review queue, the false-positive judgment calls, and every fraud loss outside Protect's scope; there's no guarantee behind you.
3-Year Total Cost of Capability
| Buy (app path) | Build (custom path) | |
|---|---|---|
| Year 0 (setup) | $0–$10,000 Signifyd integration (illustrative) | $8,000–$18,000 rule-pack + review ops |
| Years 1–3 (recurring) | ≈$480,000–$840,000 guarantee fees (illustrative) | ≈$400,000–$560,000 review labor + retained fraud losses (illustrative) |
| 3-year total | ≈$490,000–$850,000, fraud losses covered | ≈$410,000–$580,000, losses outside Protect still yours if the rate climbs |
- † All figures illustrative samples for the reference scenario — not quotes, not verified pricing.
- † Signifyd column: the guarantee fee modeled at an illustrative 0.4–0.7% of $40M screened GMV, with approved-order fraud losses covered by the vendor; Signifyd and Riskified are both quote-based (verified Sep 2026), so Riskified would land in a comparable illustrative band.
- † Build column: Shopify Protect where eligible plus the Flow rule-pack and part-time review labor, with the store retaining fraud losses outside Protect's scope at the reference 0.3% dispute rate; false-positive costs excluded on both sides because neither party invoices them.
What the Sticker Price Hides
On the buy path
- — Both guarantees bill outside the Shopify invoice (verified Sep 2026), so the fee never appears in Shopify's app-charge itemization; track it as a finance line, not an app line
- — Percentage-of-volume pricing scales with growth, not with fraud: double the revenue, double the fee, even if disputes stay flat
- — False-positive declines are silent revenue loss: nobody invoices you for the good customer turned away, and most stores never audit the decline log (community-reported pattern)
- — Guarantee fine print varies: friendly-fraud and item-not-received coverage, category exclusions and chargeback-type carve-outs need contract-level reading
On the build path
- — Shopify Protect's scope is narrow by design: US stores, Shop Pay transactions, fraud-based chargebacks only, and a seven-day tracked-shipment rule (verified Sep 2026); miss one condition and the order is unprotected
- — Rules decay silently: fraud adapts, and last quarter's rule-pack quietly stops catching this quarter's pattern
- — A card-testing wave can bury a manual review queue in a weekend, exactly when fulfillment promises are tightest
- — Every loss outside Protect's scope is yours; a bad quarter lands on your P&L with no guarantee behind it
What Merchants Say
Guarantee-app complaints cluster on decline pain: good repeat customers refused at checkout with no reason the merchant can see, override or explain to them.
The recurring math thread: merchants who ran the fee against their actual fraud losses found they'd paid multiples of what they were losing; the counter-thread is the store that dropped coverage right before a card-testing wave.
If You Change Your Mind Later
If you bought and outgrow it
Mechanically simple, financially abrupt: the day the guarantee ends, fraud losses are yours again at whatever rate fraud currently runs. Export your dispute and decline history first, since it's the dataset that prices your next negotiation, and have the Flow rule-pack live before you uninstall, not after. Expect a probing period; fraud tests newly unguarded doors.
If you built and want out
Nothing strands: Shopify Protect is a setting, and Flow rules, order tags, verification scripts and dispute templates stay yours. Stepping up to Signifyd or Riskified later is days of integration, not a migration, and you arrive with your own dispute history, which is exactly the position you want when a vendor quotes a percentage of your volume.
When This Answer Changes
We're watching for:
- ▸ Shopify Protect expanding beyond US stores, Shop Pay transactions or fraud-only chargebacks (verified Sep 2026 scope); each expansion moves the WAIT line up
- ▸ Your dispute-rate trendline crossing roughly 0.3% of orders (illustrative threshold), the line where guarantee math starts to pencil
- ▸ Signifyd or Riskified publishing pricing on the Shopify listing; both are quote-based today (verified Sep 2026), so a listed rate would let the crossover be computed
Verdict change log:
No changes since first publication (September 2026).
Common Questions
Is Signifyd or Riskified better for a Shopify store?
Signifyd is the default for mid-market Shopify stores past roughly 0.3% disputed orders: the most-referenced Shopify install base, free to install with a quote-based guarantee billed separately (verified Sep 2026). A 14-day trial lets you measure approval lift first. Riskified is a peer bought through an enterprise sales process; its listing shows 4.8★ on 33 reviews and publishes no price (verified Sep 2026). At enterprise scale, run both through one RFP on your dispute history.
Does Shopify Protect replace Signifyd or Riskified?
Shopify Protect replaces a guarantee only for a narrow slice: fraud-based chargebacks on eligible Shop Pay transactions, US stores only, on Shopify Payments (verified Sep 2026). Each order must ship with a tracking number within seven days via an approved carrier. Protect is free and covers order cost and chargeback fee, but excludes non-delivery, defect, damage and misrepresentation disputes. Orders paid any other way get no reimbursement, which is where the guarantees earn their fees.
How much do Signifyd and Riskified cost on Shopify?
Signifyd and Riskified both publish no price: each is free to install, with the guarantee fee quoted and billed outside your Shopify invoice (verified Sep 2026). Guarantee fees in this category run as a percentage of screened order volume (illustrative model), so the bill scales with revenue rather than with fraud. Run the pencil test before signing: fraud losses plus review labor plus provable false declines, against the quoted fee, at your real dispute rate.
Your Next Steps
If you're going with BUY
- Pull twelve months of disputes, declines and review hours; that dataset prices any quote you receive
- Run Signifyd's 14-day trial against your decline log and count approvals gained, not just fraud stopped
- If you're at enterprise scale, put Riskified in the same RFP with identical order samples and coverage questions
- Read exclusions before rates: friendly fraud, item-not-received and category carve-outs decide what the guarantee pays
- Diary an annual re-quote; screened-volume fees grow with revenue even when fraud doesn't
If you're going with CUSTOMIZE
- Make every eligible order Protect-eligible: Shopify Payments, Shop Pay, tracked shipment within seven days via an approved carrier
- Build the Flow rule-pack: auto-hold high risk, tag and route medium risk, ship the rest
- Add a verification step for borderline orders in your brand's voice instead of blanket declines
- Write the review SLA and dispute templates, and chart the dispute-rate trendline monthly against the 0.3% line
