Solar billing software for California
Recurring monitoring contracts, warranty plan billing, and per-system loan installment tracking — with a customer portal where homeowners see their plan, payments, and warranty coverage in one place.
Why California matters for solar dealers + installers
California's agency density and end-client diversity make it the largest US market for Vendasta resellers — and the one where billing operations move the needle most.
From the LA basin to the Bay Area to the Central Valley, California marketing agencies handle a uniquely wide vertical mix: hospitality, tech-adjacent B2B, healthcare, ag, real estate, and a deep long-tail of consumer-services SMBs. Average retail rates run higher than the national mean, which makes per-client margin reporting the single biggest unlock once you cross 50 active clients.

FAQ — Solar billing in California
Is HubWho a good fit for solar dealers + installers based in California?+
Yes. HubWho supports solar dealers + installers nationwide — every US state including California — with the same flat $29-$249/mo pricing. ACH via Plaid + Stripe Connect + Authorize.net work from any US bank. The per-client margin report and white-label customer portal are identical regardless of which state you operate in.
Can I bill monthly monitoring fees as a recurring subscription?+
Yes — every homeowner becomes a client in HubWho, and you can attach as many recurring subscriptions as the system needs. Monitoring contracts, extended warranty, panel-cleaning subscriptions — each with its own start date, billing cadence, and auto-draft.
Does it integrate with Enphase Enlighten or SolarEdge?+
Not directly — those platforms expose production data, not billing data. HubWho is the billing+portal layer; keep your monitoring portal alongside. If homeowners want a single login, we can iframe-embed production data into the HubWho portal as a custom widget (enterprise feature).
Can I bill financed systems — split a $30k install across 60 months?+
Payment plans go up to 12 months out of the box. For 60-month loan amortization you'd typically use a 3rd-party solar lender (GoodLeap, Sunlight, etc.) — HubWho handles the recurring monitoring + warranty side, the lender handles the system financing.
