Why working capital is the #1 growth constraint for solar sales orgs
The solar sales cycle creates a structural cash-flow problem: deals are closed and materials must be procured weeks before the lender funds the project. A growing sales org closing 20 deals per month — each with $15,000 in material costs — can easily have $300,000–$500,000 of working capital tied up in the pipeline at any given time.
Most sales orgs manage this with a combination of credit lines, supplier payment terms, and cash reserves. All three options have costs and limits. A credit line at 7% annual interest on $400,000 in materials costs $28,000 per year before any overhead. That's margin that goes to a lender instead of your business.
Direct Pay through Seamless Home eliminates the exposure entirely. Materials are procured and delivered based on each deal's BOM without requiring upfront payment from the sales org or installer. The capital cost goes to zero — which means growing your deal volume doesn't require growing your credit line in lockstep.
Frequently Asked Questions
What is Direct Pay in solar and how does it affect working capital?+
Direct Pay is a material procurement model offered by Seamless Home where the platform purchases and delivers panels, racking, inverters, and BOM components on behalf of the sales org or installer — without requiring the org to front the cost. This eliminates the working capital gap that occurs when an org must pay for materials before the lender advances funds after installation.
How much working capital does a solar sales org typically need?+
It depends on deal volume and material cost per deal. At 15 deals per month with an average system cost of $35,000 and 45% material cost, materials alone represent ~$15,750 per deal. With a 60-day gap between material delivery and lender funding, a sales org may have 30 deals in various stages of the pipeline at once — requiring $472,500 in working capital just for materials. This calculator shows that number for your specific deal flow.
How long after installation does a solar lender typically advance funds?+
Funding timelines vary by lender and product. Loan lenders (GoodLeap, Mosaic, Sunlight Financial) typically advance funds within 30–60 days of permission to operate (PTO). TPO providers (LightReach, Sunnova) may fund at or after installation. Some lenders have milestone-based advances; others fund at a single point. The 30–90 day range in this calculator reflects the most common band across Seamless Home's lender network.
Does Direct Pay apply to both sales orgs and installers?+
Yes. Sales organizations use Direct Pay to eliminate the need to front material costs while the deal is in permitting and installation. Installers use it to procure materials without tying up their own working capital in inventory. Both use cases route through Seamless Home's fulfillment platform, which manages procurement and delivery based on the deal's BOM.
