Not legal or financial advice. Partial disputes, split refunds, and issuer partial chargebacks follow processor and network rules that change. Confirm amounts and fields in your live dashboard. This page is merchant defense when only part of a charge is disputed. It does not coach cardholders on filing chargebacks. No invented win-rate percentages.
Ops opens the case. The original sale was $240. The dispute is $89 for one line item. Someone asks whether to fight the $89, refund the whole order, or write a response that keeps the rest of the sale intact. The social object is not a full-order rant. It is a clean partial response that maps the disputed slice to evidence and leaves the undisputed amount alone. That is the moment this page is for.
People searching partial dispute response, partial chargeback, or how to respond when only part of a charge is disputed usually get generic chargeback blogs and refund policy pages. Useful background. This page is narrower. It frames how merchants write a description and evidence index for the disputed portion, then routes that pack through Pingpong CASE MAKER.
Primary CTAs: write your dispute description, win disputes, chargeback evidence checklist. Package: chargeback documentation package. Pays for itself: pays for itself. Hub: dispute cases.
Pays for itself: fighting a soft full-order letter when only one SKU is in play burns fee, goodwill, and time. A tight partial pack (or a clean partial refund when proof is thin) is cheaper than defending the wrong amount. Confirm every disputed dollar with your processor. No fake guarantees.

What a partial dispute usually means
Issuers and processors sometimes let a cardholder dispute only part of an authorization: one shipment in a multi-item order, one billing period in a subscription window, a tip or tax slice, or a single invoice line. Your console may show a dispute amount lower than the original charge. Treat that amount as authoritative for the response. Do not invent a full-order defense when the case is scoped to a subset.
Related shapes: incorrect amount (incorrect amount chargeback response), credit not processed (credit not processed chargeback response), and merchandise returned when only one unit came back (merchandise returned chargeback response). Partial response is the framing when the dispute amount itself is already sliced.
Merchant ritual for a partial response
- Write down original amount, disputed amount, and undisputed remainder. Screenshot the console fields.
- Name which line items, shipments, or periods fall inside the disputed dollars. Leave the rest out of the narrative.
- Inventory evidence that speaks only to that slice: delivery for that SKU, usage for that seat, refund offer for that line, cancel timestamp for that period.
- Decide fight, partial refund, or accept. Soft proof on a small slice often means refund the slice and close.
- If you fight, run Pingpong on a description that maps claim to attachments for the disputed dollars only.
Hard line: legitimate defense of real sales only. Do not stretch undisputed items into the packet to pad the story. Do not fabricate line-level proof.
Where Pingpong sits
Pingpong pressure-tests the partial dispute description and evidence index. Default chain: Grok, then Perplexity, then ChatGPT, then Gemini, then Claude. Later labs catch full-order theater, AVS overstated as identity, and attachments that belong to the wrong SKU.
Write path: write your dispute description. Letterhead pack: win disputes (first PDF free; Plus $19.99/mo includes 5; extras $12 or 10-pack $99; Pro 25/mo). Packing list: chargeback evidence checklist. Agent path: dispute evidence API, API for agents, Stripe dispute API.
Paste shape
Processor NAME. Dispute ID. Reason code. Original amount. Disputed amount. Undisputed remainder. Line items or periods inside the dispute. Cardholder claim. Evidence inventory with status. Deadline DATE. Ask: write my merchant dispute description for the disputed portion only, mark soft claims, list omissions, and say whether a partial refund is cleaner than fighting. Do not invent proof. Do not paste full PAN, CVV, bank passwords, or government IDs you are not allowed to store.
When to skip
Skip pocket-change accepts, counsel-owned cases, and months where your acquirer already owns the response. Save the free eligible review for mid-ticket partial packs where a full-order letter would miss the actual claim.
