If you are seriously evaluating contractor financing in 2026, these four names come up in every conversation: Hearth, Wisetack, GreenSky, and Improvifi. Each one serves a legitimate need. Each one charges differently. And depending on your volume, job sizes, and how your team sells, one of them will cost you significantly less than the others.
Here is the complete side-by-side breakdown.
How Each Platform Charges You
The fee model is the most important thing to understand before comparing anything else.
Hearth charges a flat annual subscription (approximately $1,799 per year on the most popular plan, as of 2026). Zero dealer fees per job. Finance one project or five hundred this year, you paid the same annual amount.
Wisetack charges 3.9% per funded loan with no monthly or annual fee. Promotional 0% APR products stack additional fees on top: 4.9% for 6-month promo, 6.9% for 12-month, and 9.9% for 24-month. You only pay on loans that actually fund.
GreenSky charges dealer fees per transaction with no annual or monthly fee. Standard loans run 3 to 6%. Promotional 0% APR products push those fees to 8 to 15%+ depending on the promotional term. The cost of 0% APR on GreenSky is among the highest in the industry.
Improvifi uses a membership model that bundles multi-lender financing access with training tools, a live deal support desk, and a mobile app. Improvifi does not publish pricing publicly. Lender fees apply per transaction through their connected lending partners. Contact Improvifi directly for current membership pricing.

The Volume Break-Even Analysis
The right platform depends heavily on how much you finance per year. Here is how the math shakes out at different volume levels.
At $30,000 in annual financed volume:
- Hearth: $1,799 (flat)
- Wisetack (3.9%): $1,170
- GreenSky (avg 8%): $2,400
- Winner: Wisetack
At $50,000 in annual financed volume:
- Hearth: $1,799 (flat)
- Wisetack (3.9%): $1,950
- GreenSky (avg 8%): $4,000
- Winner: Hearth and Wisetack are nearly equal. Hearth is cheaper against GreenSky by over $2,200.
At $100,000 in annual financed volume:
- Hearth: $1,799 (flat)
- Wisetack (3.9%): $3,900
- GreenSky (avg 8%): $8,000
- Winner: Hearth by a wide margin
At $250,000 in annual financed volume:
- Hearth: $1,799 (flat)
- Wisetack (3.9%): $9,750
- GreenSky (avg 8%): $20,000
- Winner: Hearth. Not close.
Where Each Platform Fits Best
Hearth is the best fit for contractors who are actively using financing as a core part of how they sell, finance more than $46,000 per year, regularly quote jobs above $25,000, or want proposal and contract software bundled with their financing tools. Hearth also works best for contractors who want to serve customers with FICO scores in the 550 to 600 range that other platforms decline.
Wisetack is the best fit for contractors just getting started with financing who want no upfront commitment, service businesses with typical job tickets under $25,000, and operations that value the fastest possible homeowner approval experience (under 60 seconds). Wisetack is the easiest on-ramp to contractor financing.
GreenSky still makes sense for contractors who have existing manufacturer integrations that route through GreenSky, HVAC dealers tied to brands that offer GreenSky promotional products as part of a dealer program, or contractors who specifically need the $100,000 loan cap on large jobs but cannot qualify for Hearth’s subscription model.
Improvifi is the best fit for contractors who are new to financing and want training and coaching alongside the tools, operations with a sales team that needs structured education on how to present financing in the home, and contractors who have tried financing before but struggled with adoption. Improvifi’s combination of lending access and training content is unique in the space.
The Hybrid Strategy: Running Two Platforms
Many contractors do not pick just one. A common combination:
- Hearth as primary: flat annual fee covers unlimited financed jobs at any size up to $250,000
- Wisetack as secondary: free to keep active, useful for smaller same-day service calls where speed matters and the $25,000 cap is not an issue
The cost of running both is roughly $1,799 per year plus whatever Wisetack fees accumulate on the secondary jobs you send through it. For most contractors, that total is still far below what they would pay GreenSky on the same volume.
Adding EnerBank as a third option specifically for storm restoration and insurance deductible scenarios is also common in HVAC and roofing, because EnerBank’s Zero Interest Loan product is genuinely superior for that specific use case.
What About Improvifi vs Hearth Specifically?
The most direct comparison is between Hearth and Improvifi, since both are multi-lender marketplace platforms that provide more than just a financing link.
Hearth is better if you want a transparent, fixed annual cost and a clean financing-plus-software stack. The pricing is published, the lender network is defined (18 plus partners), and the software tools (proposals, contracts, invoices) are mature.
Improvifi is better if you want training and sales coaching built into your subscription, need a live deal desk to troubleshoot in-home loan issues in real time, or are rolling out financing across a sales team that has never done it before. Improvifi’s Deal Desk support is a differentiator Hearth does not offer.
The Bottom Line
For most contractors who are actively pushing financing as a sales tool and crossing $50,000 or more in annual financed volume, Hearth wins on cost by a margin that grows larger every dollar above that threshold.
Start with Wisetack if you want no commitment and are testing the concept. Add Hearth when your financed volume justifies the annual subscription. Keep GreenSky only if you have a manufacturer relationship that requires it. Consider Improvifi if you need training alongside the tools.
The combinations that work best are built around your volume, your job sizes, and how well your team actually uses the platform. The most expensive financing platform is the one you signed up for and never used.
