Chargeback alerts are the cheapest way to keep disputes off your record: you refund a customer who's already complained to their bank before the complaint becomes a chargeback. The two big alert networks, Visa's RDR and Mastercard's Ethoca, work very differently. Here's how each one works, what they cost, and how to set them up so you stop chargebacks without refunding away your margin.

Why alerts exist

A chargeback hurts three times: you lose the sale, you pay a fee (for example $15 on Shopify Payments in the US), and the dispute counts toward the ratio your processor watches. Under Visa's Acquirer Monitoring Program (VAMP), the merchant "Excessive" threshold dropped to 1.5% in April 2026, and Visa excludes disputes resolved through pre-dispute solutions from that ratio.

Alerts are those pre-dispute solutions. They catch the dispute between the customer calling their bank and the chargeback being filed. You give the money back once, skip the fee, and keep the case off your ratio.

The short version: RDR (Rapid Dispute Resolution, from Visa's Verifi) is Visa-only and fully automatic: you set rules ahead of time, and qualifying disputes are refunded and closed before they become chargebacks. Ethoca Alerts (Mastercard) send you a real-time notice from participating issuers, mostly Mastercard with some Visa, and you refund within a short window to stop the case escalating. They cover different cards and issuers, so most ecommerce brands need both. The skill is in the refund rules and the per-alert price. Apptics Shield runs both at partner rates.

What is an RDR alert?

RDR is a Visa pre-dispute program run through Verifi, a Visa company. Instead of telling you about a dispute and waiting for you to act, RDR makes the decision for you based on rules you've already set:

• You define the rules: for example, auto-refund any Visa dispute under a set amount, or for certain dispute reasons.

• Visa's systems apply them instantly: when a cardholder disputes a matching transaction, it's refunded through Visa's messaging and closed.

• Resolved cases don't count as disputes in Visa's ratios.

Best for: high volumes of low-to-mid-value Visa orders, where speed matters more than reviewing each case.
Watch out for: rules that are too broad. RDR doesn't stop to ask, so a blanket rule refunds orders you might have won or that were worth fighting.

What is an Ethoca alert?

Ethoca is a Mastercard company that connects card issuers with merchants. When a participating issuer gets a fraud claim or dispute, it can send an alert through Ethoca so the merchant can act first.

• You get a real-time alert with the transaction details.

• You choose the action: refund, cancel the order, or stop fulfillment before it ships, within the response window.

• If you refund in time, the issuer doesn't escalate the case into a chargeback.

Best for: Mastercard volume, higher-value orders where you want to review before refunding, and catching fraud before you ship.
Watch out for: coverage depends on which issuers participate and on matching your billing descriptor, and alerts expire if no one acts on them.

RDR vs Ethoca: side by side

Do you need both?

For most ecommerce brands, yes. RDR only covers Visa, and Ethoca's reach depends on participating issuers, so running one leaves a share of disputes uncovered. Coverage is the number to watch. In Apptics' published case study, alert coverage went from 62% to 97% after setup, and the merchant's dispute ratio dropped from 2.1% to 0.31% in 90 days.

What alerts can't do

• They don't erase fraud reports. Visa's VAMP ratio counts issuer fraud reports (TC40) separately from disputes (TC15). An alert refund stops the dispute, but a fraud report the issuer already filed still counts. Fraud screening before you ship still matters.

• They don't help with disputes already filed. Those need evidence and representment.

• They cost money on every alert, so a bad refund rule can cost more than the chargebacks it prevents.

Setting refund rules that protect margin

1. Segment by order value. Auto-refund low-AOV orders, where fighting costs more than the order. Send high-AOV orders to a human first.

2. Segment by reason. Fraud claims on orders that haven't shipped: cancel and refund. "Not received" claims with delivery confirmation may be worth reviewing.

3. Act within the window, every time. An expired Ethoca alert is a chargeback you paid to hear about.

4. Check for invalid alerts. Duplicates and alerts for orders already refunded shouldn't be billed.

5. Review monthly. Watch the ratio, coverage and cost per alert together.

Buying alerts directly vs through a partner

You can contract alerts directly or through a chargeback app, usually at list price, and run the rules yourself. Or you can use a partner that buys at volume rates and runs them for you. Apptics Shield is the second kind:

• Partner-priced RDR and Ethoca alerts. Apptics says that's 30–50% less than buying directly. In its published case study, the average cost fell from $28 to $15 per alert.

• No monthly fee, no lock-in. You only pay for valid alerts, and invalid alerts are credited automatically.

• Auto-refund rules for low-AOV orders and agent review for high-AOV orders, run by a 24/7 team.

• Plug-and-play with major processors (Stripe, Shopify Payments, PayPal and high-risk merchant accounts), using your processor and CRM data. About 5 minutes to connect.

• Recovery for disputes that still land, through Apptics' official Disputifier partnership. Apptics is also an official Chargeblast partner.

Critical questions answered

What are chargeback alerts?
Notifications (or automatic resolutions) that let a merchant refund a disputed transaction before the issuer files it as a chargeback, avoiding the chargeback fee and keeping the case off the merchant's dispute ratio.

What is the difference between RDR and Ethoca?
RDR is Visa-only and resolves disputes automatically using your pre-set rules. Ethoca sends real-time alerts from participating issuers, mainly Mastercard, and you refund within a window to stop escalation.

How much do RDR and Ethoca alerts cost?
It varies by provider and volume. Through Apptics Shield, RDR alerts are $13-19 and Ethoca alerts $17-27 per alert, with no monthly fee.

Do chargeback alerts help with friendly fraud?
Yes. Many friendly-fraud disputes are refunds the customer would have accepted. Refunding through an alert resolves them without a chargeback. Clear billing descriptors and easy refunds reduce them further.

Do alerts count toward my chargeback ratio?
Disputes resolved through Visa pre-dispute programs are excluded from Visa's VAMP dispute count. Fraud reports filed by issuers are counted separately.

The bottom line

RDR and Ethoca do the same job in two different ways. RDR is automatic and Visa-only; Ethoca is real-time and mostly Mastercard. Together they cover far more disputes than either one alone. What separates good alert programs from expensive ones is coverage, refund rules tuned to order value, and the price you pay per alert.

Key takeaway: Run both networks, set refund rules by order value, act on every alert, and pay partner rates, not list price.
