Square Dispute Evidence: the Pack for Each Reason, and the 7-Day Trap
Square notified you of a dispute — and started a clock most sellers only notice when it has already run out. This guide gives you the evidence pack for each Square dispute reason, the 7-day dashboard trap that loses otherwise winnable cases, and the refund-or-challenge choice you have to make before you submit.
By Muhammad Umer, founder of Chargeback Clock. Last updated October 31, 2026. Every pack below is drawn from Square’s own dispute documents; sources are named at the end.
Square does not decide dispute outcomes — the customer's card-issuing bank does, on the evidence Square routes to it. That is why the reason matters more than the volume of evidence. Square frames disputes as fraud or non-fraud: fraud means the cardholder says they did not authorize the transaction; non-fraud means they did not receive the goods or service, the goods or service was not what they expected, or the charge was incorrect. A fraud dispute asks whether the real cardholder agreed to the payment, so delivery proof alone does not answer it. A not-received dispute asks whether the customer got what they paid for, so billing information alone does not answer it. The packs below follow Square Support, "Prepare documents to challenge disputes" (article 7891) (updated April 23, 2026, checked October 31, 2026) item for item. Where Square lists an item, it is in the pack; where it does not, it is not — this guide invents nothing. One step comes before every pack: review what Square already collected on your behalf — transaction details, customer information, and payment records — in Dashboard > Orders & payments > Disputes, and check it matches the disputed payment before you add anything.
Square then simplifies the rest to three questions: describe what happened with this transaction; upload additional evidence specific to your service type; and add any other relevant details about the dispute. Keep the answers factual, clear, and concise — that is Square's own instruction, and it is also what a bank reviewer can actually use. Never store a customer's CVV in any form, and never highlight uploaded documents: the bank reviews a black-and-white copy, so highlighted text may be unreadable.
The five packs
Fraud — did the real cardholder authorize this payment?
Square warns these can be challenging to win, and says so plainly. Send: the invoice or itemized receipt; signed proof of satisfactory delivery (or, for a service, proof of service completion with date and customer signature); email correspondence with the customer about the transaction; and the terms of service the customer accepted. If the card was tapped or inserted with Square hardware, say so: Square notes sellers are protected from fraud disputes on chip cards when the chip is inserted or the card is tapped with Square hardware. Do not claim that protection for a card-not-present payment. For card-not-present sales, Square recommends its free Risk Manager tool for catching risky online payments — as prevention for the next sale, not as evidence for this one. If there was a contract for the sale, include it; if there was none, do not create one after the fact.
Not received — did the customer get the goods or service?
Send: signed proof of satisfactory delivery (goods) or proof of service completion with date and customer signature (services) — this is the core of the pack; tracking that stops before delivery does not prove receipt. Add the invoice or itemized receipt so the bank can match the proof to the disputed charge, the appointment confirmation (services) or delivery details (goods), and messages showing how you tried to resolve the issue — Square lists resolution messages as evidence the bank weighs. If you offered a reschedule or redelivery, include the specific dates you proposed and the customer's reply.
Not as described — does what arrived match what you sold?
The goods or service arrived but was not what the customer expected. Send: the description of the goods or service as sold — the listing, menu, quote, or service description as it appeared at purchase, which is the standard the bank compares the delivery against. Next to it, put signed proof of satisfactory delivery or service completion with date and signature, showing what was actually delivered. Add the invoice or itemized receipt, and messages showing how you tried to resolve the issue: an offer to fix, replace, or re-do the work, and the customer's reply. Where the terms of service actually describe what was promised, include the relevant clause — not the whole document. If you offered a partial refund, include the itemized receipt showing the transaction breakdown and the refund amount; if you offered a credit voucher, prove it was provided and state how long it remains valid.
Incorrect charge — was the amount right, and charged only once?
Square's non-fraud category expressly includes charges that were incorrect for the goods or service. Send: the itemized receipt showing the breakdown of the transaction amount, so the bank can see the charged amount was correct — or see plainly that it was not. Add a short factual explanation of what happened: what was charged, why, and, if there were two charges, what each was for. If a contract or quoted terms show the agreed price, include it. And be honest with yourself first: Square gives you two choices on every dispute — provide a refund or challenge it. If the charge genuinely was wrong or duplicated, refunding or accepting is the honest route, and Square strongly recommends issuing any refund through Square, back to the card used for the original payment. Challenging a charge you know was wrong wastes the window and the bank's patience.
Cancelled — charged after cancelling, or a cancelled service
Square's service-evidence list is built for this case, even though Square frames it inside non-fraud rather than as its own category — this guide says so rather than pretending Square publishes a separate cancelled-dispute page. Send: the refund and cancellation policies the customer accepted at purchase, as they saw them; the customer's acknowledgment of those terms; the cancellation records and notifications about this booking or subscription — what the customer was told and when; and, if the service was delivered after the claimed cancel date, proof of service completion with date and customer signature. If the service was not delivered, do not claim it was — the refund route is the honest one. Add messages showing how you tried to resolve the issue, including any reschedule, credit voucher, or partial refund you offered, with specific dates where you proposed them.
The 7-day trap
Square's 7-day trap: the window that closes while you gather evidence
Here is the trap, in Square's own words. From Square Support, "Manage payment disputes" (updated April 23, 2026, checked October 31, 2026): "Once you receive the initial notification email, you will have seven days to submit your information." Seven days — not seven business days, not thirty days, and not the card network's window. The information request form in your Dashboard shows the exact deadline for your dispute, and that deadline governs: if it differs from a date you computed yourself, use the form's date. From article 7891: "If you don't respond to the dispute, Square's dispute team will challenge the dispute with the information available." Square's Developer docs say the same from the other side: if the due_at deadline passes with no action from the seller, Square automatically challenges the dispute on the seller's behalf. In other words, silence does not pause the case — it submits a thin one. The practical rule: work to two days before the deadline, not to the deadline itself, so a missing document or a failed upload cannot eat the whole window. Enable dispute notifications in Dashboard > Orders & payments > Disputes > Settings > Notifications for each business location, and make sure the team member with the "Respond to disputes" permission actually receives them — Square notes that team members with only "View disputes" permission do not receive notifications.
Two claims this guide deliberately does not make. First, it does not state a network window (such as "about 30 days") behind Square's 7-day dashboard window: Square's own seller-facing pages publish no such number, and a number Square does not publish cannot be the basis for waiting. Second, it does not repeat the Developer docs' "typically 14 days or less" sandbox note as a seller rule — that note describes API test behavior, not the dashboard deadline Square gives sellers. If your dispute form shows a different deadline than seven days from notification, the form wins.
The refund-or-challenge choice
Two choices on every dispute — pick by the evidence
Square's process step is blunt: once you have read the dispute, you can either provide the customer with a refund or challenge the dispute. There is no third option, and no way to do both. Refunding a charge you can prove was valid costs the sale; challenging a charge you know was wrong costs the window and, when the bank sees the itemized receipt, the case. The evidence pack above is the decision tool: if the pack for your reason is complete and factual, challenge; if the honest answer to the reason's question goes against you — you did charge twice, the customer did cancel first, the service was never delivered — refund through Square, back to the original card, and keep the proof. Square's communication guidance rewards sellers who can show they tried to remedy the issue: partial-refund offers with itemized receipts, credit vouchers with validity periods, and reschedule offers with specific dates all strengthen a response — but only when they are real offers already made, not promises invented for the form.
The submission trap
Submit means done — and the file rules that reject packs
From article 7891: "Once you submit the information request form to Square, additional information can not be shared with the bank." Review the whole pack before submitting — there is no supplement step for sellers. The one exception runs the other way: Square may reach back out if the bank needs more information, and that request will come with its own short deadline. File rules, from the same article: submit only HEIC, JPEG, PDF, PNG, or TIFF files; files should be no larger than 5 MB and no longer than 15 pages; if your evidence is larger, submit only the most relevant pages or sections. You can submit from a smartphone by tapping Choose file and photographing the document. Do not highlight anything — the bank's copy is black and white.
After you submit
Up to 90 days, a final decision, and no appeal through Square
If you are challenging, the bank can take up to 90 days from the start of the dispute to make its final decision, and Square states it cannot speed that timeline up. During that time the disputed funds stay held — Square placed an immediate hold when it notified you, withholding funds from your Square balance or debiting your linked bank account, and if it could not hold the full amount your balance shows the negative disputed amount until future payments cover it. When the decision arrives, Square notifies you by email and updates the Disputes section of your Dashboard. The outcome is final: Square will not continue challenging the dispute on your behalf, and if you want to pursue it further you must resolve it with the customer directly or seek legal recourse. One exception to the bank-decides rule: if the disputed payment was made with Afterpay, Afterpay decides the dispute, not the card-issuing bank. And one fee fact worth repeating because it surprises sellers used to other processors: Square states there are no fees for dispute management services for chargebacks — it covers the fee for every dispute you work together to challenge. That covers the management fee, not the disputed amount itself.
Guide questions
It depends on the reason: fraud needs the invoice, correspondence, terms accepted, and delivery or completion proof (plus card-present proof where the card was tapped or inserted); not received leads with signed delivery or service-completion proof; not as described pairs the description as sold with what was actually delivered; incorrect charge is the itemized receipt plus a short factual explanation; cancelled leads with the refund and cancellation policies the customer accepted and their acknowledgment of the terms.
Seven days from the initial notification email. The information request form in your Square Dashboard shows the exact deadline for your dispute, and that deadline governs. If you miss it, Square challenges the dispute with the information available.
No fee for dispute management services — Square covers that fee for every dispute you work together to challenge. The disputed amount itself is still held from your balance or bank account until the bank decides.
The customer's card-issuing bank decides; Square does not determine or influence the resolution. Once the bank decides, the outcome is final and Square will not continue challenging on your behalf. The bank can take up to 90 days from the start of the dispute.
No. Once you submit the information request form, additional information can not be shared with the bank. Review the whole pack before submitting.
