You got paid weeks ago. The job is done. Then the email lands: PayPal, Stripe, or your card processor is reviewing a dispute the client filed against the charge. Your money is frozen, a fee is already on your account, and the platform is asking for evidence in 7 to 10 days. A demand letter is still the right move, but the one you send now has to do something different: it has to address the dispute itself, the platform's reason code, and the path to small claims if the client wins the chargeback.
What Changes When the Dispute Is With a Processor
A normal unpaid invoice sits between you and the client. A processor dispute brings in a third party that already took the money back from your account. PayPal, Stripe, Square, and credit card issuers run their own evidence-based review with strict deadlines and narrow reason codes.
Your demand letter no longer just asks for payment. It puts the client on notice that filing a chargeback on completed work is reversible through small claims, and that fees and interest are now stacking. Our guide on writing a chargeback demand letter covers the credit card side. This post focuses on PayPal, Stripe, and similar platforms freelancers actually use.
Fight the Processor Dispute Before You Write the Letter
Submit your evidence to PayPal or Stripe before you draft a single word of the demand letter. The platform's window is short and you only get one shot.
What to upload as evidence:
- The signed contract or accepted proposal, with the client's name and date
- The original invoice with terms and the work description
- Delivery proof: signed completion, photos with timestamps, files delivered, access logs
- Every email and message where the client approved work or said it was finished
- A short written narrative (under 500 words) walking the reviewer through the timeline
Match the evidence to the reason code. "Service not provided" needs delivery proof. "Service not as described" needs the scope document and any sign-off. "Unauthorized transaction" needs the agreement showing the client authorized the charge.
What to Include in the Demand Letter
Send the letter to the client in parallel with the processor response, not after. Waiting for the dispute outcome gives the client another two to three weeks to dig in.
- Your full contact info and the client's legal name and address
- The invoice number, original payment date, amount, and the date the dispute was filed
- The platform name (PayPal, Stripe) and the case or dispute ID
- A plain summary of the work delivered and the client's prior acknowledgment
- The processor fee the client now owes you on top of the original amount (usually $15 to $20)
- A demand: withdraw the dispute within 7 days or pay the full amount plus the fee
- A statement that you will file in small claims if the client wins the chargeback or ignores the letter
Do not threaten fraud charges or use language you can't back up. Stick to the facts: work was delivered, the client accepted it, the dispute is not supported by the record.
Address the Reason Code Directly in the Letter
Quote the exact reason the client gave the processor. PayPal shows it as "Item not received" or "Significantly not as described." Stripe shows codes like "product_not_received" or "credit_not_processed."
Refute it in one paragraph with dates. Example: "You filed a PayPal dispute on June 14 claiming the service was not delivered. The attached email from May 28 shows you confirmed receipt of the deliverables and approved final invoice INV-118."
This paragraph matters because the client will likely forward your letter to PayPal or Stripe, and the reviewer will read it. Write it like a reviewer is the audience.
Reference Small Claims Court by Your State
Most freelance disputes fall inside small claims limits, which means you do not need an attorney and the filing fee is modest. State the specific limit for your state in the final letter.
| State | Small Claims Limit | Typical Filing Fee |
|---|---|---|
| California | $12,500 (individuals) | $30 to $75 |
| Texas | $20,000 | $54 |
| New York | $10,000 (NYC) | $15 to $20 |
| Florida | $8,000 | $55 to $300 |
| Illinois | $10,000 | $75 to $225 |
If you are unsure about lien rights or larger amounts, those vary by state and project type, and you should consult a licensed attorney before going beyond small claims.
How to Send the Letter
Send the letter two ways: email (so it lands fast and creates a digital record) and certified mail with return receipt to the client's billing address on the invoice. Certified mail proves delivery, which matters if you end up in court.
Keep a folder with the invoice, the dispute notification from the processor, your evidence submission, the demand letter, and the certified mail receipt. That folder is what you bring to the courthouse if it goes that far. The same paper trail you would build for a client invoice dispute after the job applies here, with the processor case ID added.
What Happens After the Deadline
Three outcomes are realistic. You win the processor dispute and the money returns to your account: the client may still owe you the dispute fee, which the letter put them on notice for. You lose the processor dispute: the demand letter and certified receipt now feed directly into a small claims filing. The client withdraws the dispute after reading the letter: not rare, especially when the case ID is referenced and the small claims limit is spelled out.
Whichever way it goes, the next step is filing in small claims. Our guide on suing a client in small claims court covers the filing, service, and hearing.
Getting the Letter Written
The tricky part is the tone. The letter has to be firm enough to make the client reconsider, factual enough to forward to PayPal or Stripe without hurting your case, and specific enough to your state's small claims rules to mean something. PaperHammer drafts all three escalating versions (polite, firm, final demand) in about five minutes for $19, with the processor case ID and your state's small claims limit built in. You review and edit before you download the PDF. Not a law firm, just the document done right the first time.
