They call instead of writing
This is the single most common and most damaging mistake. A phone call creates zero paper trail. The company representative can say anything, promise anything, and deny everything later. Every dispute communication — every single one — must be in writing. Email, certified mail, or the company's official dispute portal. Nothing else. If you have a conversation on the phone, follow it immediately with a written recap: "Per our conversation today, I was informed X. I am documenting this for my records."
They miss the dispute window
Most contractor agreements require you to dispute a deduction within 5–14 business days of it appearing on your settlement. After that window, you may permanently forfeit your right to contest the charge. Contractors miss this deadline constantly — either because they don't know it exists or because they're waiting to "calm down" before responding. Don't wait. File your dispute immediately, even if you don't have all your evidence yet. You can supplement later.
They respond emotionally
An angry, accusatory first response does three harmful things: it signals that you're not prepared to escalate professionally, it gives the company grounds to dismiss you as unreasonable, and it contaminates your paper trail. Arbitrators and company dispute managers respond to organized, professional, evidence-driven communication. Channel your frustration into building an airtight case.
They negotiate the amount instead of disputing liability
One of the most effective company tactics is to offer a partial refund before you've formally disputed the charge. Many contractors accept this partial settlement and move on — not realizing they've effectively waived their right to contest the remainder. If you decide to accept a partial payment, include explicit written language stating that acceptance does not constitute a settlement of the full claim and you reserve all rights.
They delete their records
Most contractors don't know a damage claim is coming until it shows up on their settlement — weeks after the delivery. By then, they've cleared their phone, updated their app, and can't retrieve the delivery photos. Keep all delivery photos, GPS records, and app confirmations for a minimum of 90 days. For high-value deliveries, keep them indefinitely. Back them up off your device.
They don't request the company's documentation
Most contractors respond defensively — they try to prove they didn't cause the damage. The more effective approach is offensive: demand the company produce its documentation. What is the damage report? Who conducted the investigation? What photos do they have? What is the basis for the dollar amount? In most cases, the company has nothing. No documentation means no valid basis for the deduction. If they refuse to produce documentation, that refusal is itself evidence of bad faith.

A first denial from a company dispute department is not the end of the road. It's often an automated or template response from someone whose job is to minimize reversals. The dispute process has multiple levels: initial dispute → demand letter → BBB complaint → arbitration. Most companies settle long before arbitration because maintaining a dispute is expensive for them too. Contractors who escalate consistently win far more often than those who stop at the first denial.
Learn more →They don't use professional language and templates
There is a measurable difference in response rates between contractors who send informal emails and those who send structured, professional dispute letters. The format signals that you understand the process, that you've documented your case, and that you're prepared to escalate. Companies have seen every type of contractor complaint. A professional dispute letter with numbered exhibits reads as a legal filing in progress — and gets treated accordingly.
Learn more →They don't read their contractor agreement
Your contractor agreement defines exactly what deductions are authorized, what documentation is required, what deadlines apply, and what escalation path exists. Most contractors have never read the full document. Companies know this — and they draft their agreements to be long and complex precisely because contractor ignorance is their greatest defense. Read your agreement. Specifically look for the deduction authorization clause, the dispute window, and the arbitration clause.
Learn more →They assume they can't win
The biggest mistake is the one contractors make before they even start: assuming the company is always right, that the process is rigged, that it's not worth fighting. The data tells a different story. Contractors who file structured, documented disputes recover a significant percentage of challenged deductions. Companies issue many charges specifically counting on the fact that 90% of contractors won't push back. The 10% who do recover their money — and often get future claims handled more carefully.

Avoid every one of these mistakes
The Dispute Builder guides you through a professional, documented response for your specific dispute type. No guessing. No emotional emails. Just the right steps in the right order.
The Pattern Behind Every Mistake
Every mistake on this list has the same root: contractors treating disputes as personal conflicts instead of procedural processes. Companies have dispute departments. They have standard responses. They have policies designed to minimize reversals. The only way to beat a system built to deny you is to operate within a system built to win.
That means: written communication only, proper documentation, professional templates, and a clear escalation path. It means reading your contract before you dispute, not after. It means treating every deduction as a formal business matter — because that's what it is.
Stop losing disputes you should be winning.
