Chargebacks for contractors: How to win the dispute.
A client filed a chargeback weeks after paying you? Here's why it happens, how to fight it, and the paperwork that decides who keeps the money.
You finished the job. The client paid. Weeks later, the money vanishes from your account and your payment processor says the client "disputed the charge."
That's a chargeback — and for contractors, it's one of the most frustrating ways to lose money you already earned. The good news: chargebacks are winnable, and most losses come down to one thing — missing paperwork. Here's how the process works and how to protect yourself before the next job.
What is a chargeback?
A chargeback happens when a client contacts their bank or credit card company and disputes a payment instead of talking to you. The bank pulls the money back from your account while the dispute is investigated. You're presumed guilty until you prove otherwise, and you typically get one shot to submit evidence.
Chargebacks were designed to protect consumers from fraud. But in the contracting world, they're often used as a weapon — a way for a client to get free work by claiming the job wasn't done, wasn't authorized, or wasn't done right.
Why contractors get hit with chargebacks
After years working in fraud prevention and financial operations, I can tell you most contractor chargebacks fall into a few buckets:
"Services not rendered." The client claims you never did the work. This is the most common — and the easiest to beat if you have proof of completion.
"Not as described." The client says the work didn't match what was promised. Without a written scope of work, this becomes your word against theirs — and banks side with cardholders in he-said-she-said disputes.
"Unauthorized transaction." The client claims they never approved the payment. A signed payment authorization kills this argument instantly.
Friendly fraud. The client knows exactly what they're doing. They got the work, and they want the money back too. It's a bigger problem than most people realize — Visa estimates friendly fraud can make up as much as 75% of all chargebacks.
How to fight a chargeback (and actually win)
When the dispute notice arrives, you'll be asked to submit a rebuttal or evidence package. Banks are looking for documents, not stories. The strongest packages include:
- A signed contract or work order showing the client agreed to the scope and price.
- A signed payment authorization proving the client approved the charge.
- A completion certificate or sign-off — the client's signature confirming the work was finished and accepted.
- Dated photos of the completed work.
- A paper trail of communication — texts or emails showing the client was satisfied (or at least never complained before disputing).
Submit everything by the deadline, keep it organized, and label each document. It's worth the effort: industry data shows merchants win roughly 45% of the chargebacks they actually fight — and the ones who win are the ones with signed documentation. A clean, professional evidence package tells the bank you run a real business. Sloppy or missing paperwork tells them the opposite.
The real fix: win it before it happens
Here's the truth most contractors learn the hard way: the dispute is decided by what you collected before the client ever picked up the phone. If your process includes signatures at every stage, you're nearly chargeback-proof.
The signature habit
- Before the job:signed contract, signed scope of work, signed payment terms.
- During the job:signed change orders for anything that shifts scope or price. Verbal changes are how disputes are born.
- After the job:signed completion certificate, final walkthrough sign-off, and photos.
None of this requires a lawyer or an office manager. It requires having the right forms on your phone and making signatures a habit on every job — even the small ones. Especially the small ones. Clients who dispute charges rarely announce themselves in advance.
Chargeback FAQs
How long does a client have to file a chargeback?
Typically up to 120 days from the transaction, depending on the card network — and in some cases longer for services. That job you finished in March can come back to bite you in July.
Do contractors ever win chargeback disputes?
Yes — regularly, when they submit signed documentation. Contractors lose when their only evidence is an invoice and their own account of events.
Can I just refuse card payments to avoid chargebacks?
You can, but you'll lose jobs. Many clients expect to pay by card, and check-only policies can read as a red flag. Documentation protects you without shrinking your customer base.
What if the client disputes a deposit?
Same rules apply. A signed agreement stating the deposit amount, what it covers, and whether it's refundable is your defense. Never take a deposit on a handshake.
