Financing Chargebacks and Cancellations: What Contractors Should Know
Loans funded 58% of at-home residential solar purchases in 2023 (CFPB, 2024), and the same financed-purchase pattern shows up across battery storage, EV chargers, and water filtration. Given that, cancellations and disputes on financed projects aren't a rare edge case. In fact, they're a routine part of running a financing program.
Most contractors plan carefully for the sale and the install. Few plan for what happens when a customer cancels inside the rescission window, or disputes the work months after it's done. This guide covers four things: what a cancellation actually triggers, and what "chargeback" means in this context (it's not one thing). It also covers a dealer's legal obligations, and how to structure a financing process that avoids most of these outcomes in the first place.
> Key Takeaways
> - Loans funded 58% of at-home residential solar purchases in 2023 (CFPB, 2024), so financed-project cancellations and disputes are common, not exceptional.
> - Federal law gives most home-solicitation buyers a 3-business-day right to cancel (FTC, 16 CFR Part 429), and the FTC Holder Rule lets a customer raise contractor misconduct against whoever holds the loan.
> - "Chargeback" means two different things in contractor financing: a card-network dispute on a deposit, and a lender clawing back funds already released to the dealer.
> - Milestone-based funding and signed completion documentation are the practical levers that keep a dealer out of both.

What Happens When a Customer Cancels a Financed Project?
Federal law gives most home-solicitation buyers a 3-business-day window to cancel a contract over $25. The seller must then refund any payments within 10 business days of a valid cancellation (FTC, 16 CFR Part 429). That window is known as the Cooling-Off Rule: a federal rule that gives certain buyers a short, unconditional right to cancel a contract, and it applies regardless of what your contract says.
Specifically, during that window the rules are strict. No work starts, no materials get delivered, and no funds get disbursed against the project. A customer who cancels within the statutory period gets a clean exit. The related financing agreement has to be cancelled without penalty to them. That's a different situation from ordinary buyer's remorse after the window closes. Once the rescission period ends, cancellation becomes a matter of your contract terms, not federal cancellation rights.
In practice, most point-of-sale lenders build this window directly into their disbursement schedule. That way, a dealer never advances money against a project that's still legally cancellable. It's the first, and simplest, protection against chargeback exposure: nothing gets paid out until the customer's legal right to walk away has expired.
For the day-count and disclosure detail by state, see state-by-state cancellation windows, since several states extend the federal 3-day floor.
What Does "Chargeback" Actually Mean in Contractor Financing?
"Chargeback" carries baggage from retail card disputes. In contractor financing, though, it means two distinct things, and conflating them causes real confusion. Defining both at the outset makes the rest of this guide unambiguous.
A card-network chargeback is a customer dispute of a deposit or partial payment made by credit card. The card issuer reverses the charge under card-network dispute rules, separate from anything the financing program does. A dealer chargeback, sometimes called a clawback, is different: it's a lender reversing or withholding funds already released to the dealer because a project was cancelled, never completed, or successfully disputed by the customer. In short, these two events are governed by entirely different rulebooks. One runs on card-network policy; the other runs on your dealer agreement with the lender.
To be clear, industry-wide chargeback data mostly describes the first kind. Friendly fraud, meaning a customer disputing a legitimate charge, drives an estimated 40-80% of e-commerce chargeback disputes, according to a 2025 industry estimate from Chargeflow and Datos Insights. However, that figure comes from card-not-present e-commerce transactions, and it doesn't map directly onto point-of-sale installment financing for a home improvement project. It's useful background on why "chargeback" feels loaded, not a same-industry rate for what a dealer actually faces.
How Does Milestone-Based Funding Limit Chargeback Exposure?
Point-of-sale lenders in the solar and home-improvement space commonly release contractor payment in tranches tied to project milestones, rather than a single lump sum at signing. That's according to Stoel Rives' The Law of Solar: Project Finance for Solar Projects. Typical stages include the rescission period clearing, installation completing, and inspection or permission-to-operate sign-off.
In effect, this structure protects both the lender and the dealer. If a milestone is never reached, the next tranche simply never gets released. There's no "clawing back" of funds that were never disbursed in the first place. By contrast, a single-disbursement model pays the full amount out at signing. Any post-signing cancellation or dispute then means a genuine clawback of money the dealer has already spent or booked as revenue.
Importantly, fast financing decisions and disciplined milestone funding aren't the same thing, and mixing them up leads to bad assumptions about risk. For how decision speed and install timelines actually relate, see financing decision speed and realistic install-timeline expectations.
What Are a Contractor's Legal Obligations When a Project Is Cancelled?
Under the Cooling-Off Rule, once a customer cancels within the statutory window, the contractor must refund any payments. The related financing agreement must also be cancelled without penalty to the consumer (FTC, 16 CFR Part 429). That refund has to happen within 10 business days of a valid cancellation, and nothing about the financing structure changes that obligation.
State law frequently stacks additional requirements on top of that federal floor. For example, California's SB 517 and AB 1327, effective January 1, 2026, extend the state's home-improvement contract cancellation rights. They also add mandatory contractor contact-information disclosures and subcontractor notice requirements (Mayer Brown; SunRay Notice). The exact day count reported for California varies slightly between legal sources. So, don't quote a specific number without confirming current statutory text. Describe it as an extended window instead, and check the state-specific rule before relying on it.
The practical takeaway: the federal rule is a floor, not a ceiling. As a result, a contractor operating in multiple states needs a process that satisfies the strictest applicable state requirement, not just the federal minimum. Otherwise, a cancellation dispute risks turning into a compliance problem.

What Happens When a Customer Disputes a Financed Project After Installation?
The FTC Holder Rule is a federal rule that lets a customer raise contractor misconduct, defective work, or an undelivered promise as a claim or defense against whoever holds the loan. Recovery under the rule is generally capped at the amount the customer has already paid under the contract (FTC Holder Rule, 16 CFR Part 433; LegalClarity). In other words, a post-install dispute becomes the lender's problem too, not just the contractor's. That's why lenders care about install quality even though they don't do the work themselves.
Above all, documentation is a contractor's primary defense here. A signed completion certificate, dated install photos, and an inspection or permission-to-operate sign-off turn a "he said, she said" dispute into a paper trail that resolves quickly. Without that documentation, though, a lender investigating a dispute has little to go on besides the customer's account of what happened.
This is a different situation from a pre-funding denial, where the loan never got approved in the first place. A post-install dispute happens after funds are already out. That's exactly why milestone funding and clean paperwork matter so much. For the contrast, see how to handle a financing denial.

Under the Holder Rule, a customer can hold a loan holder responsible for a contractor's misconduct, with recovery generally capped at what the customer already paid (FTC Holder Rule, 16 CFR Part 433). That single rule is why a dealer's documentation habits directly affect a lender's risk. It's also why lenders that fund on verified milestones tend to see fewer of these disputes reach that point at all.
How to Avoid Financing Chargebacks and Cancellations
Clear scope, realistic timelines, and signed milestone documentation are the practical levers a dealer actually controls. The legal rules above set the floor; they don't determine your exposure. A dealer's own process does.
In practice, a short operational checklist covers most of it:
- Put written scope and price in the contract before signing
- Set install-timeline expectations that match permitting and utility reality, not an optimistic guess
- Collect a signed customer completion confirmation at handoff
- Stay responsive during the rescission window instead of going quiet
- Vet a financing partner's fee structure and disclosures before offering the program

Beyond the checklist, fee transparency matters too. The Consumer Financial Protection Bureau has flagged lenders folding markup, or "dealer," fees of 10-30%, in some cases over 50%, into loan principal without clear disclosure (CFPB, August 2024). A program with an opaque fee structure is also more likely to produce a surprised, disputing customer later. For that reason, tracking cancellation and dispute rate as an ongoing KPI matters as much as tracking approval rate or ticket size.
> What we see across Eos Loan originations: In our experience, dealer partners who collect a signed completion confirmation at handoff and work with milestone-based funding see meaningfully fewer post-install disputes. We've compared them against partners relying on a single lump-sum disbursement and informal sign-off, and the gap is consistent. We treat documentation habits as a leading indicator of a partner's dispute risk, well before a chargeback ever happens.

Before adding any financing program, run it against a vetting checklist for a financing partner and understand how dealer fees work and where they hide. By way of example, Eos Loan is a direct lender, not a marketplace or broker, and charges no dealer fee. That structural difference removes one common source of downstream disputes. For a fuller set of monthly benchmarks, see contractor financing metrics to track.
Do State Rules Stack on Top of Federal Cancellation Rights?
Put simply, federal law, the Cooling-Off Rule, is the floor. Several states extend the cancellation window or add disclosure and notice requirements on top of it. On top of that, starting March 1, 2026, PACE-financed home-improvement loans get additional mortgage-style protections under a CFPB final rule (CFPB PACE final rule).

Frequently Asked Questions
How long does a customer have to cancel a financed home improvement contract?
Federal law gives most door-to-door and home-solicitation buyers a 3-business-day right to cancel (FTC, 16 CFR Part 429). Several states extend this window, so confirm current state-specific text before relying on a particular day count.
What happens to the loan if a customer cancels during the rescission period?
The contractor must refund any payments made, and the related financing agreement must be cancelled without penalty to the consumer within the federally required 10-business-day timeline (FTC, 16 CFR Part 429).
Can a customer dispute a financed project after installation?
Yes. Under the FTC Holder Rule, a customer can raise contractor misconduct or undelivered work as a claim against the loan holder, with recovery generally capped at amounts already paid (FTC Holder Rule, 16 CFR Part 433).
What is a dealer chargeback in contractor financing?
It's distinct from a card-network chargeback. A dealer chargeback is a lender reversing or withholding funds already released to the dealer because a project was cancelled, never completed, or successfully disputed, as opposed to a customer disputing a card charge with their card issuer.
How can contractors reduce cancellation and chargeback risk?
Set realistic install timelines at the outset and collect a signed completion confirmation at handoff. Keep documentation like photos and inspection sign-off, and work with a financing partner that funds on verified milestones rather than a single lump-sum payment.
The Bottom Line on Financing Chargebacks and Cancellations
A cancelled or disputed financed project isn't a lender failure or a fluke. It's a predictable event with well-defined rules. To recap: the federal floor plus state add-ons govern cancellations, "chargeback" means two different things depending on who's disputing what, and milestone funding plus documentation are the practical defense against both.
None of this replaces legal advice. Rules vary by state and change over time, so consult qualified counsel for state-specific or program-specific questions. What a dealer controls is process: clear scope, realistic timelines, signed completion documentation, and a financing partner whose disbursement structure matches the risk. Get that right, and most cancellations and disputes resolve as routine paperwork instead of a fight.
