Wisetack vs Hearth vs GreenSky: What Contractor Financing Actually Costs You

Short answer first. If you finance a handful of jobs a year, Wisetack is almost certainly your cheapest option, because you pay 3.9% only on the jobs that close and nothing the rest of the year. If financing is a normal part of how you sell and you are running double-digit financed jobs annually, Hearth flips the math, because it is a flat annual subscription with zero per-loan dealer fees. And GreenSky is the incumbent that most big HVAC, roofing, and window companies still run on, with promotional loan products your customers love and merchant fees you will only see after you ask for a rate sheet.

The reason these three feel impossible to compare is that they do not charge the same way. Once you see the three fee models, the decision takes about five minutes.

Three Fee Models, Not Three Companies

Every contractor financing program on the market bills you one of three ways.

Per transaction. A flat percentage of every financed job. You pay nothing to join and nothing in a slow month. The platform makes money only when you do.

Flat subscription. One annual price whether you finance two jobs or two hundred. Expensive if you barely use it. Very cheap per job if financing is part of every pitch.

Dealer fee by loan product. The lender charges you a merchant fee that changes based on which loan the homeowner picks. A plain installment loan might cost you almost nothing. A true 0% APR promotion can cost you a large double-digit percentage of the job, because somebody has to fund that interest-free period and it is you.

That third one is where contractors get hurt, and it is the one nobody explains at the trade show booth.

Wisetack: Flat 3.9%, Only When You Close

Wisetack publishes its pricing right on the site, which is already unusual in this category.

There is no implementation cost and no subscription fee. You pay a flat 3.9% per transaction fee when a customer completes financing. That is it. If you go three months without financing a job, you pay nothing for three months.

The mechanics fit how residential work actually happens. You text or email the homeowner a prequalification link and they see their real approval amount from a soft credit check before you ever finalize the bid. When you agree on price, you send an application link, they pick their terms, and you do the work. The customer confirms the job is done and the money lands in your bank account within one to three business days.

The numbers on the program: jobs from $500 up to $65,000, terms from three months to ten years, and 0% APR options up to 24 months. Consumer offers range from 0% to 35.9% APR depending on the amount and the customer's credit, with no prepayment penalties, no origination fees, no late fees, and simple rather than compounding interest. Wisetack is integrated with more than 30 field service and CRM platforms, including JobNimbus, Jobber, Housecall Pro, FieldPulse, and Workiz, so for a lot of contractors the financing link shows up automatically on the estimate they were already sending.

One honest caveat on the 0% offers. Wisetack's help documentation says if a customer qualifies for and selects an extended 0% APR plan, you are charged a higher fee tied to that plan. Short 0% plans and interest-bearing options stay at 3.9%. So "flat 3.9%" is true for the vast majority of what you will run, and not quite true for the longest promotional offers. Ask what the extended-plan fee is before you advertise 24 months interest free.

Wisetack's own merchant survey reports that jobs financed through the platform run about 4.5 times larger than jobs paid another way and that 87% of businesses won a job because they offered it. Those are their numbers from their own customers, so weight them accordingly, but the direction matches what most contractors report once monthly payments show up on the estimate.

Best for: contractors financing anywhere from a couple of jobs a year up to roughly ten, and anybody who wants to test whether financing actually moves their close rate without committing a dollar upfront.

Hearth: A Flat Subscription and Zero Dealer Fees

Hearth runs the opposite model. You pay an annual subscription, and you pay nothing per loan.

That is the whole pitch, and for the right contractor it is a very good one. Hearth's marketplace runs 18-plus lenders with $0 dealer fees, which means your bid does not have to absorb a merchant fee no matter which product the homeowner picks. Hearth publishes that most companies invest $2,000 to $6,000 a year depending on level of service, plus a one-time $99 setup. The specific tier prices are not on the pricing page; you get them from a rep.

The tiers are Hearth Pro, Pro + Harper, and Enterprise. Pro is the financing marketplace, quotes with monthly payments built in, 0% intro credit card offers for homeowners, digital payments, client management, and a concierge team that walks homeowners through to approval. Pro + Harper adds their AI assistant, which answers calls, texts leads back, follows up on estimates you approve, and chases financing applications to funded. Enterprise adds a marketing audit, a dedicated account manager, and hands-on implementation.

Two structural things worth knowing. First, Hearth is a technology company licensed as a broker, NMLS ID 1628533. It does not make loans and does not make credit decisions; its lending partners do. Second, and this is the underrated part, contractors using Hearth are not subject to underwriting or revenue requirements, because the homeowner is the one applying for a personal loan. If you have been declined by a dealer program because your company is young or your volume is small, that matters.

Hearth reports 20,000-plus contractors on the platform and more than $500 million in jobs funded. Their marketing cites lending partners working with FICO scores as low as 550, amounts from $1,000 to $250,000, and terms from two to twelve years.

Best for: contractors where financing is part of the standard pitch, not the fallback. If you are presenting monthly payments on most estimates, the flat fee gets cheap fast.

GreenSky: The Incumbent With the Rate Sheet You Have to Ask For

GreenSky is the biggest name in home improvement financing and has been for years. It was acquired by Goldman Sachs in 2022 and sold to a Sixth Street-led consortium in 2024, and it remains dominant in HVAC, roofing, and windows, the categories where big-ticket promotional financing sells work.

What GreenSky does well is the promotional product. Deferred interest plans, extended reduced-rate plans, and true 0% APR offers are exactly what a homeowner wants to hear when you are quoting a $28,000 roof, and GreenSky's approval infrastructure and dealer network are deep.

What you need to go in knowing: GreenSky does not publish merchant fees publicly. You get them in a dealer rate sheet after you are in conversation with them, and the fee changes by loan product. Historically published dealer rate sheets show standard installment products at a very low merchant fee and true 0% APR plans running well into double digits as a percentage of the financed amount. Treat any specific percentage you read on a third-party blog, including the ranges floating around this year, as unverified. Get your own rate sheet in writing and read the whole thing.

Two other line items to hunt for on that sheet. Low-volume or monthly minimum fees, which historically appeared on GreenSky dealer sheets for merchants under a set monthly funded volume. And whether your agreement prohibits surcharging the dealer fee to the homeowner as a separate line item, which lender agreements commonly do. If you cannot pass it through, it comes out of your margin or gets buried in your price, which makes your bid less competitive against the guy paying 3.9%.

Best for: high-ticket exterior and mechanical companies doing real volume, where a 0% offer is the difference between winning and losing a $30,000 job and the fee is a budgeted cost of sale.

Side by Side

Figures are each company's own published information as of September 2026, except GreenSky's fee structure, which is not published.

The Math That Actually Decides It

This is arithmetic, not a study, and you can run it on your own numbers in two minutes.

Take your last twelve months. How many jobs did you finance, and what was the average ticket? Multiply them. That is your financed volume.

Twenty financed jobs at a $12,000 average is $240,000 of financed volume. At 3.9%, that costs you $9,360 a year. A $4,000 flat subscription covering the same volume costs you $4,000. Flat wins by more than five grand.

Now run four financed jobs at $12,000. That is $48,000 of volume, or $1,872 at 3.9%. The same $4,000 subscription now costs you more than double. Pay-per-use wins.

The break-even lands somewhere around $51,000 to $154,000 of annual financed volume depending on which subscription tier you land on. At a $12,000 average ticket, that is roughly four to thirteen financed jobs a year. Under that, pay per transaction. Over it, pay flat.

And here is the part contractors miss: those numbers move when financing changes your behavior. If offering monthly payments takes your average ticket from $9,000 to $14,000, the flat subscription looks better on both sides of the equation, because you are financing more jobs and each one is bigger. Do not just price your current volume. Price the volume you are trying to build.

Three Mistakes That Cost Real Money

Quoting a 0% offer before you know what it costs you. The homeowner hears interest free. You eat the merchant fee. On a fee-heavy 0% product that can be a double-digit percentage of the job, which is more margin than most remodelers make on the whole thing. Know the fee for every product you are allowed to present.

Treating the fee as overhead instead of pricing it in. If financing costs you 3.9% and you are not accounting for it anywhere, you are quietly running a discount program. Build it into your pricing the same way you build in card processing, which we broke down in our guide to payment processors for contractors.

Signing up for a program and never presenting it. The most expensive financing program is the one you pay for and forget. If it is not on the estimate template and in the sales conversation by default, it will not get used. Our guide to offering financing covers how to actually put monthly payments in front of homeowners, and your estimating software probably has a field for it already.

How to Actually Decide

Count last year's financed jobs. If it was under five, start with Wisetack, because it costs you nothing to have it sitting there ready. If it was over fifteen, get a Hearth quote and run the arithmetic above against your real volume. If you sell $25,000-plus exterior or mechanical jobs where a 0% offer closes deals, get a GreenSky rate sheet and read every fee line before you sign anything.

If you are somewhere in the middle, which most residential contractors are, there is no rule against running two. Plenty of companies keep a pay-per-use option for the occasional job and a promotional program for the big ones. Just make sure your salespeople know which to present and why, or they will default to whichever one is easiest to click.

The Bottom Line

Wisetack is the low-commitment choice with published, predictable pricing. Hearth is the flat-fee choice that gets cheaper the more you use it and never charges you per loan. GreenSky is the big-ticket promotional choice where the offer is powerful and the fee schedule is something you have to go get.

Whichever way you go, get the fee for every loan product in writing before your first customer sees an offer. Financing should make you more money, not quietly refinance your margin.
