Understanding Discover Chargeback Reason Code SV: Services Not Rendered

Discover Reason Code SV occurs when a cardholder claims they paid for a service, but it wasn't delivered on time, or didn't happen at all. The code covers in-person services such as hotel stays as well as remote services like software licensing or tech support. For merchants to successfully overturn the claim, they need to supply evidence of on-time delivery. If they can't, they should refund the cardholder.

Key Takeaways

• What it means: The buyer claims the agreed-upon service was not provided by the expected date.
• Causes: Missed appointments. Late delivery. Unclear terms. Or, customers who simply change their mind.
• How to respond: Gather proof of fulfilment, contracts, usage logs, or refunded credits. Send these to the issuer inside the deadline.
• How to prevent: State service dates in writing. Confirm cancellations quickly. Subscribe to chargeback alerts to catch disputes early.

What is a Discover Reason Code SV Chargeback?

Code SV is Discover’s label for “Services Not Rendered.” The issuer grants a temporary credit to the cardholder because they claim they never received what they paid for. The rule applies to card-present and card-not-present sales, including phone, mail, and online purchases. A hotel guest who never checked in, a passenger whose tour was cancelled, or a subscriber who cannot access a cloud tool can all raise this dispute. 

The important point is that the promised activity, support, or access was due on a certain date and, in the cardholder’s view, that date passed without performance. The network lets issuers skip the normal inquiry stage if the evidence is clear, yet often a question arrives first. Merchants then have a short window to reply before the chargeback is finalised. Knowing what a code SV dispute covers helps sellers gather the right documents, prove fulfilment, and protect revenue.

Primary Causes for a Code SV Chargeback

Reason code SV tends to occur when there's a gap between customer expectation and what was actually delivered. One of the most common causes is a missed deadline. For example, a technician fails to show on time, or a software license does not activate. Scheduling clashes are another cause. If service businesses get the wrong date, mix up clients or make double bookings, the customer may file a claim under code SV. 

Refund lag can also trigger this type of dispute. If a merchant agrees to return money yet delays the credit, frustration builds, and the cardholder’s next stop is the issuer. There are also cases of fraud, where a cardholder uses the service but later claims they never received it, hoping to reclaim funds.

Time Limit for Disputing a Discover Reason Code SV Chargeback

Discover gives cardholders 120 calendar days from the service date, or from the last date it should have been provided, to raise a claim. Issuers then have to submit the chargeback to Discover no later than 30 days after receiving the complaint. Once the chargeback is filed, the acquirer sends it to the merchant, who normally has 30 days to respond, though some acquirers adopt a shorter internal cut-off. 

If no reply or evidence arrives in that time, the provisional debit becomes permanent. Merchants should mark the service date on every confirmation, as the time limit clock starts from that point. When the buyer paid for several future dates—say, a weekly cleaning plan—the limit begins the first day the service was missed. Knowing the timetable helps merchants act fast, collect proof, submit a rebuttal, and keep funds before the window closes.

What SV Means for Consumers & Issuers

For the cardholder, code SV provides valuable protection when paid-for services aren't delivered. If their rental falls through at the last minute, they can recoup the money spent. Or, if a remote tech support service fails to connect, they have an easy path to securing a refund. The existence of this code boosts consumer confidence and encourages the use of Discover cards for service payments.

For the issuer, it's a customer service exercise. It's their responsibility to judge the validity of the claim, taking both sides into account: the customer's complaint and any proof to the contrary provided by the merchant. They review the transaction and assess the evidence to decide where liability lies. For issuers, making the right call is a balancing act. Rejecting a genuine complaint may prompt customers to switch to rival banks. However, if they rule in favour of the cardholder and the merchant later provides evidence a charge was valid, the issuer will be liable for the funds.

What SV Means for Merchants

For merchants, an SV notice signals lost revenue, extra fees, and reputational damage if left unanswered. Service providers run on tight calendars and intangible fulfilment, making proof harder than shipping a parcel. Hotels, tour operators, agencies, and SaaS companies all need airtight records. 

If too many SV disputes accumulate, Discover can flag the business as high-risk, which may result in increased processing costs or even termination of the relationship. However, a well-handled SV case can end positively. When the merchant replies with strong evidence inside the window, funds stay put, and chargeback ratios improve. Treat every SV alert as a warning light to refine operations and protect revenue going forward.

How to Respond to a Code SV Chargeback

Speed and evidence are the two pillars of a winning response. Start by confirming the service timeline: booking confirmation, contract, or work order showing the agreed date. Next, gather proof that you met the commitment. For a physical task, that can be a signed service report, a photo with a timestamp, or a technician's GPS record. For digital services, pull server logs, IP access history, or activation records tied to the cardholder. 

If the claim arrived before the due date, provide the document that sets the future delivery schedule. When the buyer cancelled outside the allowed window, include a copy of your cancellation policy, display it as it appears at checkout, and show how the customer accepted it. If you have already refunded the cardholder, attach the credit receipt, including date and amount. Organise everything into a clear packet, add a short cover letter explaining why the dispute is invalid, and send it to your acquirer within their cut-off. Keep copies for your files.

Proactive Prevention: The Ultimate Defence

Stopping SV disputes before they reach the bank is the best plan. Send confirmation emails right away so customers can flag mistakes early. Use automated reminders—texts or emails—before the appointment or activation date. When delays are unavoidable, tell the customer at once and offer new options or a quick refund. Store digital proof of fulfilment in one place, making retrieval easy if a dispute pops up.
