The Contractor's Guide to Offering Customer Financing (2026)
A homeowner loves your proposal. Then they see the total, and the deal stalls. Price, not interest, is what kills most big-ticket essential projects. A customer financing program fixes that: your customer pays over time while you get paid right away, so sticker shock stops ending good deals.
This is the part of the sales process most installers and dealers underuse. Battery energy storage, EV chargers, and water filtration are exactly the projects where a monthly payment changes the answer from "maybe next year" to "let's schedule it." This guide walks the full 2026 playbook: what a contractor financing program is, why it lifts your close rate, how dealer fees actually work, and how to pick the right partner.
> Key Takeaways
> - A contractor financing program lets customers pay over time while you collect in full at install, turning price-sensitive prospects into buyers.
> - The financing partner is your biggest decision. A direct lender like Eos Loan funds loans itself and charges no dealer fees; a marketplace routes you through third parties.
> - US residential storage reached 2.7 GW in 2025, up 92% year over year (Wood Mackenzie, 2025), expanding the projects you can finance.
> - The residential clean-energy credit (Section 25D) ended December 31, 2025 (IRS), making financing the primary affordability lever for residential pitches in 2026.

What is a contractor financing program?
A contractor financing program is an arrangement that lets your customers pay for a project over time while you, the installer, get paid right away. Price stops being the reason a deal dies. In 2025, total US energy storage installations reached 18.9 GW, up 52% year over year (Wood Mackenzie, US Energy Storage Monitor, 2025), so the projects worth financing keep growing.
The mechanics are simple. You present a project. The customer chooses to pay in monthly installments instead of one lump sum. A lender funds the loan, the customer repays the lender, and you receive your payment without waiting. That immediate payment matters for your cash flow as much as the lower payment matters for theirs.
There are two ways contractors do this. The first is sending the customer off to find their own bank loan, which is slow and often loses the deal. The second is offering financing at the point of sale, inside your sales conversation, so the customer never has to leave to shop for money. Point-of-sale financing keeps you in control of the deal.
A contractor financing program lets customers pay over time while the contractor collects payment right away, and demand is climbing fast: total US storage hit 18.9 GW in 2025, up 52% year over year (Wood Mackenzie, 2025). For installers in battery energy storage, EV chargers, and water filtration, that growth is a direct reason to make financing a standard part of every quote.
Your role stays focused on selling and installing. The lender handles underwriting, disclosures, and servicing. For a deeper breakdown of how the offer reaches the customer, see our guide to point-of-sale vs. marketplace vs. direct lender.
Why does offering financing help you close more projects?
Financing converts price-sensitive prospects into buyers by reframing a large lump sum as a manageable monthly payment. That single shift lifts both your close rate and your average ticket. When the conversation moves from "can I afford the whole thing?" to "can I fit this payment into my month?", more customers say yes, and more of them say yes to a bigger system.
Here is the 2026 reason this matters more than ever. The residential clean-energy credit (Section 25D) ended December 31, 2025 (IRS, 2025). For residential buyers, that federal credit is no longer there to close the affordability gap. Financing is now the affordability lever you control at the kitchen table. This is general information, not tax advice. Consult a qualified tax professional.
Think about the math of a stalled deal. A customer who walks away costs you the full ticket, the install slot, and the referral that customer would have sent. A financed deal recovers all three. Across our partner base, the installers who present a monthly payment alongside the cash price simply lose fewer deals to price hesitation.
> Our finding: Across the Eos Loan partner base, contractors who attach financing to more than one project type, battery energy storage plus EV chargers plus water filtration, report fewer stalled deals than single-vertical sellers. We frame this as a pattern we see, not a guarantee of results.
Bigger projects benefit most. A homeowner weighing a battery energy storage system at a monthly payment is far more likely to add capacity than one staring at a single large number. The market is moving the same direction: residential storage grew 92% in 2025 (Wood Mackenzie, US Energy Storage Monitor, 2025).

How much does it cost? Understanding dealer fees
The main cost to a contractor offering financing is the dealer fee, the discount the lender takes when it funds the loan. A transparent fee protects your customer's total price. A hidden fee gets buried inside an inflated system price, which makes the advertised interest rate look lower while the customer quietly pays more overall.
Here is the trick to watch for. Some lenders advertise a very low rate, then mark up the purchase price to cover a large dealer fee. As one industry overview notes, lenders can "inflate the purchase price with high dealer fees to make the interest rate appear lower," which drives the total cost of the system up (NerdWallet, 2025). The customer sees a small rate and misses the padded price.
The honest version is the opposite: a true lower interest rate paired with a low, disclosed dealer fee. That combination genuinely reduces the cost of borrowing instead of hiding it. The number to compare is never the headline rate alone. It is the total amount the customer pays for the same system.
The main cost of a contractor financing program is the dealer fee, and transparency is the whole game: a disclosed fee protects total price, while a hidden one inflates the system price to make the advertised rate look lower (NerdWallet, 2025). Always compare the total cost for the same scope, not the headline rate.
Run the math on any financing offer
Use this four-step check on any program before you sign:
- Compare total cost, not rate. Ask for the full amount the customer repays on an identical system scope. A lower rate on a padded price is not a deal.
- Ask for the dealer fee in writing. A transparent partner discloses it. If nobody will name the fee, assume it is hidden in the price.
- Hold the system price constant. Get your cash price first, then ask what the financed price is. If the financed price jumps, that gap is the buried fee.
- Check the term flexibility. Longer terms lower the payment but change total interest. Match the term to the customer's budget, not to whatever makes the rate sheet look good.
- Make financing standard. Present the monthly payment beside the cash price on every quote, not just the ones that stall.
- Choose a direct lender with no dealer fees, so your customer's total price stays honest and your economics stay clean.
- Go multi-vertical across battery energy storage, EV chargers, and water filtration so you can finance every essential project you sell.
- Treat financing as the 2026 affordability lever now that the residential Section 25D credit has ended.

Direct lender vs. marketplace vs. point-of-sale: which model?
A direct lender funds the loan itself, so you deal with one party, transparent fees, and consistent terms. A marketplace routes your customer to third-party lenders, adding handoffs and variable terms. A point-of-sale platform is the technology layer that presents the offer, and it can sit on top of either model. Knowing which one you are working with tells you who actually owns the decision and the fee.
Eos Loan is a direct lender. We fund the loans we offer, which is why we charge no dealer fees and keep terms consistent. We are not a marketplace, a broker, or a platform that connects you to other lenders. That distinction is the difference between one accountable relationship and a chain of handoffs where nobody owns the outcome.
The contrast matters most when a deal gets complicated. With a marketplace, a borderline application can bounce between lenders, each with its own criteria, and your customer feels every handoff. With a direct lender, the underwriting answer comes from one place, and approval is subject to eligibility under one consistent standard.
A direct lender funds loans itself, giving you one party, transparent fees, and consistent terms, while a marketplace routes your customer to third-party lenders with variable terms and extra handoffs. For contractors, fewer parties usually means faster answers and clearer fee math, all subject to approval and eligibility.
| Model | Who funds the loan | Number of parties | Fee transparency | Term consistency |
| --- | --- | --- | --- | --- |
| Direct lender (Eos Loan) | The lender itself | One | No dealer fee | Consistent |
| Marketplace / broker | Third-party lenders | Several | Varies by lender | Varies by lender |
| Point-of-sale platform | Depends on the model behind it | Depends | Depends | Depends |
A quick note on compliance language. No financing model should promise approval or quote you a guaranteed rate, and none should push your customer into a self-serve signup that bypasses you. Approval is always subject to eligibility. For the deep comparison, see our guide to point-of-sale vs. marketplace vs. direct lender.
What projects can you finance? Going multi-vertical
A strong contractor financing program finances more than one project type, so you can attach financing to every essential project you sell: battery energy storage, EV chargers, and water filtration. Single-vertical financing limits you to one pitch. Multi-vertical financing lets you cross-sell, because the customer who finances one essential project is the easiest customer to sell the next one.
Battery energy storage is the anchor. With Eos Loan, battery energy storage terms range from 6 to 240 months, a span wide enough to fit almost any budget. That flexibility is a real differentiator: a short term for the customer who wants to pay it down fast, a long term for the customer who needs the lowest possible monthly payment.
EV chargers and water filtration round out the offer with flexible terms. An EV charger is a natural add-on for a household that just went solar or added storage. Water filtration reaches customers who never asked about energy at all, which widens your addressable market beyond the clean-energy buyer.
A strong program finances battery energy storage, EV chargers, and water filtration, not just one category, and battery energy storage terms run from 6 to 240 months with Eos Loan. That range lets you match the monthly payment to the customer's budget instead of forcing the project into a single fixed term.
These are essential projects, the kind of work households genuinely need, which is exactly why a payment plan lands so well. To go deeper on each, see our guides to battery storage financing, EV charger financing, and water treatment dealer financing.
How do you add financing to your sales process?
Add financing in four moves: present the monthly payment alongside the cash price, get the customer pre-qualified early, keep the paperwork digital, and train your reps to lead with payment, not price. Done together, these turn financing from an afterthought into a default part of every quote. The market rewards it: total US storage grew 52% in 2025 (Wood Mackenzie, 2025), and a smooth financing offer is how you capture that demand.
Start with how you present the number. Show the monthly payment next to the cash price on every proposal, not just the ones where the customer flinches. When the payment is always visible, customers self-select into financing without you having to sell it separately.

Pre-qualify early, before the customer falls in love with a scope they cannot afford. An early soft check, subject to approval and eligibility, tells you what payment fits and keeps you from designing a system the financing cannot support. Keep every document digital so the customer can complete it from the couch, not a fax machine.
Adding financing comes down to four moves, present payment, pre-qualify early, go digital, and train reps to lead with payment, and the demand is there: US storage installations rose 52% in 2025 (Wood Mackenzie, 2025). Reps who open with the monthly payment instead of the sticker price recover deals that price-first reps lose.
Finally, train your team to follow up on stalled deals with a financing angle. A "no" from three months ago is often a "not at that price," which a payment plan can reopen. That follow-up motion is where a lot of recovered revenue hides.
How do you choose a financing partner?
Evaluate a financing partner on five things: are they a direct lender, are dealer fees transparent, how flexible are the terms, how many verticals do they cover, and how fast is approval. A partner that scores well on all five gives you clean economics and a smooth customer experience. A partner that is strong on one and weak on the rest creates friction you will feel on every deal.
These five criteria reinforce each other. A direct lender can keep fees transparent because it controls the fee. Multi-vertical coverage only helps if the terms are flexible enough to fit each project. Fast approval only matters if the underwriting standard is consistent enough to trust. Judge the package, not a single feature.
Here is how Eos Loan maps to those five points. We are a direct lender, we charge no dealer fees, we offer battery energy storage terms from 6 to 240 months with flexible terms on EV chargers and water filtration, we cover multiple essential project verticals, and approval is handled under one consistent standard, subject to eligibility. That is the combination this guide argues you should look for.
Pick a financing partner on five tests, direct lender, no hidden dealer fees, flexible terms, multi-vertical coverage, and fast approval, and weigh them together rather than chasing one feature. Eos Loan is a direct lender with no dealer fees and battery energy storage terms from 6 to 240 months, all subject to approval and eligibility.

What about taxes and incentives in 2026?
The residential clean-energy credit (Section 25D) ended December 31, 2025 (IRS, 2025), so in 2026 residential buyers can no longer rely on that federal credit to offset the cost of qualifying projects. The commercial clean-electricity investment path (48E) generally remains available through 2032, attributed to the IRS and underlying statute. This is general information, not tax advice. Consult a qualified tax professional.
What this means for your pitch is straightforward. On residential projects, the affordability story can no longer lean on the 25D credit. Financing fills that role, because a monthly payment is the lever that still works at the kitchen table in 2026. That is why the post-credit reality makes a strong financing program more central to your close, not less.
A point of caution on language. Do not describe Eos Loan financing as a tax credit, rebate, or incentive. It is a loan that lets your customer pay over time. Keeping that line clear protects you and your customer, and it keeps your sales conversation accurate. For tax specifics, your customer should always speak with a qualified tax professional.
Frequently Asked Questions
How do contractors offer financing to customers?
Contractors offer financing at the point of sale: they present a monthly payment beside the cash price, the customer applies, a lender funds the loan, and the contractor gets paid right away. With a direct lender like Eos Loan, this runs through one party, and approval is subject to eligibility. US storage demand grew 52% in 2025 (Wood Mackenzie, 2025).
What is a dealer fee and how does it work?
A dealer fee is the discount a lender takes when it funds a loan. A transparent fee is disclosed and keeps the customer's system price honest. A hidden fee gets buried inside an inflated price so the advertised rate looks lower while total cost rises (NerdWallet, 2025). Compare total cost, not the headline rate.
Is a direct lender better than a financing marketplace?
A direct lender funds loans itself, so you get one party, transparent fees, and consistent terms. A marketplace routes your customer to third-party lenders, adding handoffs and variable terms. For most contractors, fewer parties means faster answers and clearer fee math. Eos Loan is a direct lender, not a marketplace or broker. Approval is subject to eligibility.
What projects can I finance for my customers?
A multi-vertical program finances battery energy storage, EV chargers, and water filtration, the essential projects households need. With Eos Loan, battery energy storage terms range from 6 to 240 months, with flexible terms on EV chargers and water filtration. Financing more than one vertical lets you cross-sell across your customer base. US residential storage grew 92% in 2025 (Wood Mackenzie, 2025).
Did the solar and clean-energy tax credit end?
Yes. The residential clean-energy credit (Section 25D) ended December 31, 2025 (IRS, 2025). The commercial 48E clean-electricity path generally remains available through 2032, per the IRS and statute. This is general information, not tax advice. Consult a qualified tax professional. In 2026, financing is the affordability lever for residential buyers.
The bottom line for 2026
Offering customer financing is one of the most direct ways to close more projects and raise your average ticket on essential projects. The core moves are clear:
