Chargeback

The chargeback process begins when a cardholder contacts their issuing bank to dispute a transaction - usually 30-120 days after purchase. The issuer reviews the complaint and, if they deem it valid, immediately reverses the transaction and notifies the acquiring bank (your processor). Your processor debits your merchant account for the transaction amount plus a chargeback fee (typically $15-25), then forwards you the chargeback notice with a reason code.

You now have 7-21 days (depending on card network and reason code) to respond with evidence proving the transaction was legitimate. This evidence package - called representment - must include specific documents matching the reason code: for "product not received," you need delivery tracking; for "unrecognized transaction," you need clear descriptor evidence and customer communication records; for "subscription cancelled," you need proof customer was still active.

The issuing bank reviews your evidence and makes a final decision. If you win, funds are returned to your account (minus the non-refundable chargeback fee). If you lose, the chargeback stands. In some cases, the cardholder can dispute again through arbitration (Visa/Mastercard mediation), which costs $250-500 and has high barriers to entry.

Throughout this process, the card networks monitor your chargeback rate. If you exceed thresholds (typically 0.9% for standard risk, 1.5% for high-risk), you enter monitoring programs like Visa's VDMP or Mastercard's Excessive Chargeback Program, triggering escalating fines from $5,000 to $100,000+ monthly until you fix the problem or get terminated.

For high-risk merchants, chargebacks are the #1 threat to business continuity. A merchant processing $1M monthly at a 1.2% chargeback rate faces 12,000 annual chargebacks costing $180K-1.2M in fees and lost merchandise - potentially wiping out all profit margins. But the financial damage is only part of the story.

The real danger is the TMF/MATCH list. Once your chargeback rate consistently exceeds network thresholds, your PSP will terminate your account and report you to the TMF, blacklisting you from obtaining new merchant accounts for 5+ years. For businesses in high-risk verticals like nutra, gaming, or dating - where mainstream PSPs already reject 90%+ of applications - a TMF listing essentially ends your ability to process cards through legitimate channels.

Even before termination, excessive chargebacks trigger cascading penalties: monthly fines of $5K-100K through monitoring programs, reserve increases from 10% to 30%+ (tying up massive amounts of capital), lower approval rates as issuers flag your MID as risky, and loss of negotiating leverage for better processing rates. Some merchants see their effective processing costs increase from 4% to 8-10% due to chargeback-related penalties alone.

The reputational damage extends beyond payment processing. High chargeback rates signal poor customer service, fraud problems, or deceptive business practices - making it harder to secure banking relationships, advertising accounts (Google/Facebook), and even partnerships with suppliers. In high-risk industries where trust is already limited, chargeback problems create a reputation spiral that's extremely difficult to escape.

Illustrative example — not a specific client engagement.

• A $3M/month nutra merchant reduced chargeback rate from 1.8% to 0.6% by implementing pre-chargeback alerts (preventing 400+ disputes monthly) and improving billing descriptor clarity, saving $420K annually in fees and preventing TMF listing.
• A dating platform cut subscription-related chargebacks by 65% after implementing 3-day and 1-day end-of-trial email+SMS reminders, creating documentation proving users were notified before renewal.
• An iGaming operator successfully represented 38% of fraud chargebacks by implementing device fingerprinting and capturing IP geolocation at account creation, proving accounts were created by the cardholders themselves.

• Use crystal-clear billing descriptors that include your brand name and customer support number to reduce unrecognized charge disputes
• Implement a 24-hour pre-chargeback alert system through services like Verifi or Ethoca to catch disputes before they become chargebacks
• Respond to every retrieval request within 24 hours with complete transaction details - this prevents 30-40% of potential chargebacks
• For subscriptions, send cancellation confirmations and end-of-trial reminders via email AND SMS to create paper trail
• Track chargeback reason codes weekly to identify patterns: if 40% are "product not received," your shipping process needs improvement
• Create representment templates for common reason codes with pre-organized evidence packages to ensure consistent, timely responses
• For high-ticket items ($500+), require signature on delivery and keep tracking records for minimum 180 days
• Implement robust fraud screening to prevent first-party fraud (criminals) before transactions are approved

• Ignoring retrieval requests (which often precede chargebacks) - responding to retrievals within 48 hours can prevent 30-40% of chargebacks
• Using vague or generic billing descriptors that customers don't recognize, causing "friendly fraud" chargebacks
• Failing to collect robust evidence at point of sale (IP address, device fingerprint, customer communication) needed for representment
• Not implementing clear cancellation policies for subscriptions, leading to "services cancelled" chargebacks
• Treating all chargebacks the same instead of analyzing reason codes to identify root causes
• Accepting chargebacks passively without fighting winnable disputes - properly documented representments succeed 20-40% of the time
