If you need a vendor chargeback dispute attorney in Miami, start with the contract. A vendor chargeback dispute is a fight over money your business received, or expected, that gets reversed, held, or deducted. KEW Legal, a Florida business law firm with offices in Coral Gables and Sunny Isles Beach, reviews the governing agreement first, then helps you respond, push back, or negotiate a release of funds.

What Is a Vendor Chargeback Dispute?

A vendor chargeback dispute starts when someone pulls money back from your business. The party doing it usually says it has the right to. You may believe it does not.

Common situations include:

  • Card chargebacks against your merchant account, when a card issuer reverses a sale.
  • Processor reserves or holds, where your processor keeps part of your sales as security.
  • Vendor offsets or clawbacks, where a supplier subtracts an amount from what it owes you.
  • Disputed invoices, where a vendor or customer refuses to pay and says the work or goods were unacceptable.

Your rights come from the contract. A merchant processing agreement, vendor agreement, purchase order, or online terms can each set the rules and deadlines. Florida courts apply the basic elements of contract law, including offer, acceptance, consideration, and clear essential terms, to oral contracts too, as the St. Joe Corp. v. McIver decision explains.

What KEW Legal Covers in Chargeback and Payment Disputes

KEW Legal covers the contract side of payment reversals, from the first review through negotiation and, when needed, a formal proceeding. The work includes:

  • Review of processing or vendor agreements for chargeback, reserve, holdback, notice, and dispute-window language.
  • Comparison of the reversal or deduction against the contract terms and your transaction records.
  • Written dispute responses, demand letters, and requests for the records the other side relied on.
  • Negotiation for a reversal, release of held funds, a payment plan, or corrected accounting.
  • Advice on keeping invoices, delivery proof, messages, and statements before the dispute grows.
  • Arbitration or litigation support if a negotiated result is not reached.
  • Ongoing outside general counsel review of payment and vendor terms.

If your agreement has an arbitration clause, Florida law generally treats it as valid and enforceable under the Florida arbitration statute. That clause can shape where your dispute is heard.

A court also does not throw out a term just because it seems harsh. Florida requires both unfair deal-making and unfair terms, weighed together, as explained in Basulto v. Hialeah Automotive.

How the Chargeback Dispute Process Works

The process runs in five steps, from a first consultation to negotiation or formal escalation.

  1. Consultation. You describe the reversal and share the notice and contract. Bring the dates and reference numbers.
  2. Document check. KEW Legal identifies gaps in your transaction records, delivery proof, and correspondence.
  3. Written position. You receive an outline of your response options, the likely counter-arguments, and what each path involves.
  4. Response or demand. A written response goes to the processor, vendor, or counterparty, with a request for the records they relied on.
  5. Negotiation or escalation. The aim is a release of funds or a reversal. Arbitration or court comes into play only if the contract and facts support it.

Timing matters. Response windows are often short and set by the contract or card network rules. Under Florida’s contract-shortening rule, any provision in a contract that fixes the period of time within which an action arising out of the contract may be begun at a time less than the period provided by the applicable statute of limitations is void. How long each stage takes depends on the facts, the contract, and the other side’s response.

Documents to Gather Before Your Consultation

Bring these records to your first call. Start with the notice and the contract if the rest is not yet organized.

  • The chargeback notice, reserve statement, deduction notice, or vendor letter, with dates and reference numbers.
  • The signed processing agreement, vendor agreement, master services agreement, purchase orders, and any amendments or online terms you accepted.
  • Invoices, receipts, shipping or delivery confirmations, signed acceptance forms, and service completion records for the disputed transaction.
  • Emails, texts, and portal messages with the vendor, customer, or processor about the charge or reversal.
  • Account statements showing the original payment, the reversal, fees, and any reserve or holdback amount.

Sort the records by date. Note who sent each message and when.

Common Questions About Vendor Chargeback Disputes

Can a card chargeback be disputed after it posts?

Usually, a response is possible within the deadline in the notice. The contract and card network rules shape which evidence helps.

Does the vendor contract or the processing agreement control?

Both can apply. The agreement that governs the specific payment is reviewed first.

Can my processor keep a reserve?

Reserve terms come from your agreement. KEW Legal reviews the release conditions and the basis for the hold.

Do I have to go to court?

Not always. Many disputes end through written demands and negotiation. Court or arbitration is considered only when the contract and facts support it.

Can I recover attorney’s fees?

Should I stop doing business with the vendor during the dispute?

That turns on the contract terms, ongoing obligations, and your cash flow. Those points are reviewed before you decide.

How we approach a chargeback dispute

Review the paper trail

We start with the vendor agreement, invoices, delivery records and the chargeback notice, since these shape which response makes sense.

Protect your position

We look at how the disputed payment was processed and what your contracts say about refunds, services and disputed charges.

Communicate with the vendor

Where appropriate, we work to resolve the matter directly with the vendor or its payment processor before it escalates.

Plan the next step

If a negotiated resolution is not possible, we explain the options available for your business and what each one involves.

Don't set a chargeback notice aside

Chargeback notices often include a response window. Bring the notice to counsel as soon as it arrives so a response can be prepared in time.
