Chargebacks Explained

Chargebacks explained end to end: the dispute lifecycle from reason codes to representment, what evidence wins and loses each stage, and why chargeback ratios decide which merchants stay cardable. The dispute window is the clock every digital and physical goods flow runs against.

TL;DR - Clock starts at capture - the 30-75 day window decides all physical goods math.

THE LIFECYCLE

Stage 1 - Dispute filed: cardholder (or issuer auto-detection) contests a charge; issuer opens the case and pulls funds provisionally
Stage 2 - Reason code assigned: every dispute carries a code - fraud (card-absent), authorization problems, processing errors, consumer disputes. The code decides the evidence game
Stage 3 - Merchant response window: typically 7-21 days by network to submit compelling evidence
Stage 4 - Representment: merchant re-presents the charge with evidence - delivery proof, AVS/CVV results, login history, prior undisputed transactions
Stage 5 - Resolution: issuer reviews and rules; networks can force arbitration after that

Total open time runs 30-75 days depending on network and stage - which is exactly the exposure window behind physical-goods routes.

REASON CODES THAT MATTER

Class	Story told	Evidence that fights it
Fraud - card absent	"I did not authorize this purchase"	Delivery + AVS/CVV match + device history
Authorization	Missing or duplicated auth	Auth logs, settlement records
Processing error	Wrong amount, double charge	Transaction logs and refunds issued
Consumer dispute	Goods not received or not as described	Tracking, correspondence, policy acceptance

Fraud-class disputes shift liability based on whether 3DS completed and how much verification data matched (the cashout timing math assumes the window is real).

THE RATIO GAME

Issuers monitor every merchant''s chargeback-to-transaction ratio - thresholds sit near 1% of volume across the major networks, and breaching them starts a monitoring program: higher reserves, fines per dispute, and termination for persistent offenders. Merchants under ratio pressure fight harder (full representment on every case), which is why the same merchant can be soft on intake one quarter and evidence-heavy the next quarter. The cardable framework captures this as merchant-side posture - dispute tolerance is a readable property.

FRIENDLY FRAUD VS TRUE FRAUD

Part of dispute volume is the cardholder lying (received goods, claims non-receipt), part is genuine takeover. Merchants cannot tell at filing time, so they respond to both the same way - which is why evidence quality, not case merit, decides outcomes. Digital goods carry weak evidence by default (no tracking number), so merchants in that class either eat disputes or install the checks that make the category cardable again.

WHAT THE WINDOW MEANS IN PRACTICE

Digital value: extract before day one of the dispute window opens - capture latency is the metric that matters
Physical value: resale inside the first weeks, not month three; inventory sitting past representment loses twice
Repeat-transaction evidence: one undisputed prior purchase materially improves representment odds - relevant to account-age strategies on the merchant side

The clock starts at capture, not at checkout. Plan every route against the day the money can be pulled back.
