Chargeback Risk Scorecard for Shopify Stores

Why chargebacks work differently on a Shopify store

A Shopify store rarely sees the card. Unless you also sell in person with a POS setup, almost every transaction is keyed online or paid through a wallet like Apple Pay or Google Pay. With no signature or chip read, disputes come down to what you can prove: what the customer agreed to at checkout, what they saw on their statement, and whether the package arrived.

Most Shopify disputes are not stolen-card fraud. They are customers who don't recognize the charge, claim the item never arrived, or forgot about a renewal. A store that trades as a brand name but bills under an LLC name, or a drop shipper with two-week delivery windows, can build a chargeback problem even though nobody is committing fraud.

Seasonality matters too. Many Shopify merchants do a large share of their year between Black Friday and the end of December. Disputes on those orders can arrive weeks later, after volume has dropped. Your chargeback count rises at the same moment your transaction count falls, so your ratio can jump in January or February even if nothing about your operation changed.

Getting accurate inputs from your Shopify admin

Card transactions per month: count only orders paid by card or card-based wallet. Leave out orders paid fully with gift cards or store credit. If you also run in-person sales through Shopify POS on the same merchant account, include those, because the card brands look at the account, not the sales channel. Use an average of recent months rather than your best holiday month.

Chargebacks in the last 90 days: pull this from your payment provider's disputes report, not from refunds. Include disputes you won. Ratio monitoring is generally based on disputes received, not disputes lost. Inquiries that never became chargebacks don't count here.

Fraud tools: Shopify's order risk indicators help you decide whether to cancel an order, but this question asks whether 3-D Secure and AVS/CVV checks run at your gateway. If you aren't sure what your gateway enforces, choose "not sure." The fix list will tell you to confirm it.

Billing descriptor: the fastest way to check is to buy something from your own store on a personal card and read the statement line. If it shows your legal entity or a processor name instead of the store name customers know, answer accordingly.

Worked example: a hypothetical Shopify skincare brand

These numbers are hypothetical, for illustration only. A Shopify skincare store does $60,000 a month in card volume across 800 transactions, so the average ticket is $75. It received 18 chargebacks in the last 90 days, or 6 per month. That is a 0.75% ratio, which lands in the tool's caution zone. The 0.65% caution line is the tool's own buffer, and 1.00% is the assumed Mastercard monitoring ratio. Both are assumptions, not card brand rulings. At 6 chargebacks a month, the store is far below Mastercard's 100-chargeback minimum, but its processor may still act on the ratio alone. It can absorb about 2 more chargebacks a month before reaching 1.00%.

Its answers: refund policy in the footer only, one fraud check enabled, brand-only descriptor with no phone number, subscribe-and-save with no renewal reminders, eCommerce business type. That scores 25 ratio points + 6 + 5 + 4 + 8 + 3 = 51, which is Elevated.

In the gated report, cost per chargeback is $75 in lost sales + $25 in assumed fees + $15 in assumed handling, or $115. That is about $8,280 a year: $5,400 in lost sales, $1,800 in fees, and $1,080 in staff time. This is a worst-case estimate that excludes product cost, shipping, and any card brand program fines.

Five fixes trigger. Renewal reminders and easy cancellation, and pre-dispute alerts, are each assumed to cut chargebacks 15%, worth about $1,242 a year each. Full fraud checks are assumed to cut 10%, about $828. A clear descriptor and a refund policy shown at checkout are each assumed to cut 5%, about $414 each. These reduction rates are planning assumptions, not measured results. Combined, they project a 41.3% reduction, about $3,421 a year, a projected ratio near 0.44%, and a projected score of 18 (Low). Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting.

What a good Shopify result looks like, and what to watch

A healthy result for most Shopify stores is a ratio comfortably under the tool's 0.65% caution line, measured in a normal month and not just during holiday volume. It also means a Low band, with no controls left open in the fix list. If you only clear the line in November and December, recheck in late Q1, when disputes from holiday orders have arrived and volume has dropped.

Watch the model-specific risks. Subscription and subscribe-and-save stores should send a reminder before each renewal and make cancellation easy to find. Free-trial-to-paid offers carry the highest billing-model score in this tool. Drop shippers should show realistic delivery windows on product pages and send tracking proactively, because "item not received" disputes follow long delays. Pre-order stores should state ship dates at checkout and in the confirmation email.

While you're in your statements, check what each dispute actually costs you. Look for per-chargeback fees, retrieval or inquiry fees, and gateway fees if you route through a third-party gateway. Also check whether your Shopify plan adds a platform transaction fee when you use an outside processor. These line items vary, so read your own agreement rather than relying on the tool's assumed $25 fee.
