What should a service business do when a customer disputes a charge?
Short answer
Stay calm, respond before the deadline, and let your evidence do the talking: the estimate or agreement, dated before-and-after photos, a summary of the work, any customer sign-off, and your messages with the customer. Keep it factual and organized in one place, because a clear packet is easier for a card issuer or a court to follow.
A checklist to gather
- The signed or accepted estimate or agreement
- Messages where the customer approved the work or any changes
- Before-and-after photos with dates
- A written summary of the work performed
- The customer's sign-off, if you have one
- The invoice and proof of delivery of the report and invoice
Mind the deadline
If the dispute is a card chargeback, your payment processor gives you a limited window to respond. Missing it usually means automatically losing the dispute, so check the notice date first and respond early.
Keep the tone neutral
Do not argue emotionally in your response. State what was agreed, what was done, and attach the evidence. If the relationship is worth saving, reach out to the customer separately and offer to walk through the report together.

Will having a report guarantee I win a dispute?
No. Outcomes are decided by the card issuer or a court and depend on the details. A well-organized record simply gives you the best realistic chance, and often prevents the dispute from starting.
Should I refund to make it go away?
Sometimes a partial credit is the cheapest fix and keeps the customer. That is a business decision. Refunding does not require admitting fault, but check with your processor about how refunds interact with an open dispute.
