What installers say
Fantastic company to work with. Couldn't ask for a better team. Super professional, approachable and amenable to our many requests.
Excellent service, would recommend to business associates.
You didn't get into solar to babysit a stack of half-broken tools.
Most solar businesses are running the whole operation across an inbox, a spreadsheet and a bit of luck. It works, until it doesn't.
One platform that brings the work in and runs it to install and beyond.
Every enquiry captured. Every proposal branded. Every follow-up on time. Every install handed over cleanly. Every partner paid on time. All in one place. Free to run.
- Leads lost in inboxes and WhatsAppEnquiries scattered across four people and three phones. Nothing chased on time.
- Five disconnected tools that don't talkA CRM, a proposal tool, a shared drive, a spreadsheet and a calendar. None of them agree.
- Proposals that look like a PDF from 2009Buyers open it once, print nothing, sign nothing. You never see it again.
- Deals go cold because no one followed upThe good ones stall in verbal. The team assumes someone else has it.
- No idea which marketing actually worksYou spend on ads, referrals and events. You can't tell what turned into cash.
Three built-in ways to fill your pipeline. One place to close every deal.
OpenLead, the C&I Marketplace and Referrals bring the new work in. CRM, Proposals, Forms and Ask Sonny help you win it and deliver it. Turn on what you need. It's all included.
Tasks
Follow-ups, chases and site actions, attached to the right deal with a real owner and a due date.
Calendar
Two-way sync with Google and Microsoft. Site visits and meetings in the calendar your team already lives in.
Forms
Site survey forms your team can fill in offline. Saves locally, syncs when you're back on signal.
Dashboard
The one page your team opens in the morning. Today's tasks, hot deals, calendar and pipeline value in a single view.
Reports
Pipeline funnel, revenue, lead source attribution and proposal analytics, live from your workspace.
Integrations
Google, Microsoft, Calendly, Stripe and Airtable live now. QuickBooks, Xero, DocuSign and Zapier coming.
Ask Sonny
A copilot that reads your live pipeline and helps you act on the deals that matter today.
Send a live deal room. Watch the buyer read it.
Ditch the flat PDF. Send a branded deal room the buyer can open on their phone, share with a CFO and come back to. You see every page they read and every file they download.
- Branded to your company, ready to send in minutes.
- Real-time buyer activity, so you know when to pick up the phone.
- One link for proposal, financials, site docs and next steps.
Get found on Google, and capture every enquiry.
OpenLead does two jobs at once. It optimises your Google Business Profile so more local customers find you, and it gives you a branded lead-capture tool you can add to your website, socials or email signature, or send as a link. Every enquiry lands in your pipeline with the source attached.
- Health score and prioritised fixes for your Google Business Profile.
- Branded capture tool you can put anywhere: website, socials, email signature, or shared as a link.
- Every enquiry lands in Radiant with the source tagged, ready to work.
Design the system, ready to drop into your proposal.
Lay out the array, size the system and get the numbers your customer needs to say yes, without leaving Radiant. Design, pricing and proposal all live in one place.
- Array and roof layout, sized to the site.
- System size, estimated generation and savings, ready for the buyer.
- Feeds straight into your deal room and proposal. Nothing re-keyed.
Turn partners and past customers into a proper channel.
Give every partner their own portal. They see the deals they've sent, the stage each one is at and the commission owed. You get a repeatable inbound channel that pays for itself.
- White-labelled partner portal, live commission tracking.
- Deals flow straight into your pipeline with the source attached.
- Automatic commission calc on signed contracts.
Built for both sides of solar
One platform that flexes with how you sell, whether you're closing rooftops all week or one megawatt carport a quarter.
For commercial solar businesses
Long, complex deals with multiple stakeholders. Modelled, tracked, closed cleanly.
- Stages that match reality: enquiry, survey, DNO, proposal, signed.
- Deal rooms with half-hourly data, CAPEX vs PPA and site docs in one link.
- Multi-assign teams, tasks and clear ownership on every deal.
- Referral partners run as a proper channel, not a spreadsheet.
For residential solar businesses
High-volume pipelines built for speed of response and consistent follow-up.
- OpenLead landing page turns your Google profile, website and socials into booked leads.
- Fast, branded proposals: send a deal room in minutes, not days.
- Site survey forms work offline and sync when your team is back on signal.
- Calendar sync with Google and Outlook so surveys book themselves in.
Works with the tools you already run on
Wired into your stack. No glue code.
