Coil

Coil is the AI dispatcher and office brain for HVAC shops. It runs the office so you can run the shop. When the day breaks (a tech calls off, a no-cool lands, the 4pm scramble hits), Coil rebuilds the schedule, briefs your techs, keeps invoices moving, and shows you exactly what needs attention. You approve, it executes. Built for owner-operators and small shops who answer their own phone and run the board between jobs. ASK COIL ANYTHING Chat with an AI that actually knows your shop. Ask "what's my day look like," "reschedule the Carter job to 3," or "who hasn't paid," and it acts on your real jobs, customers, and invoices, not generic advice. AI DISPATCH THAT FIXES THE DAY When something goes sideways, Coil proposes the route change, drafts the customer update, and explains the impact. You approve and move. AI ROUTE OPTIMIZATION, INCLUDED Coil reads your live board and rebalances routes automatically. What other CRMs sell as a per-tech add-on, Coil includes. AI FRONT DESK Never miss a customer. Front Desk answers inbound calls, texts, and voicemails, understands what each caller needs, and turns every one into an action card you can dispatch, reply to, or schedule in a tap. TAP TO PAY AND PAYMENTS Get paid before you leave the driveway. Tap to Pay on iPhone with no extra hardware, card on file with one-tap charge, plus ACH, cash, and check. Money lands in your shop's own account. ESTIMATES AND CUSTOM INVOICES Good, Better, Best estimates with your branding, online acceptance, and clean, customized invoices with payment links. Wisetack financing sits right in the payment flow. Estimate, sign, invoice, send, without leaving the job. MEMBERSHIPS AND RECURRING REVENUE Build service plans, auto-generate visits and reminders, and give customers a self-serve portal. Recurring revenue that runs itself. ONE SHOP RECORD THE AI RUNS ON Jobs, customers, equipment, photos, invoices, memberships, and tech notes live together. Coil's AI works from that real context, not a chatbot bolted on the side. A TECH APP THEY WILL ACTUALLY USE Your tech's whole day in their pocket: job context, equipment history, photos, and closeout. Snap the equipment data tag and Coil reads the model and serial for you. Run the shop, not the software. Tap to Pay on iPhone and payments run through Stripe Connect to your shop's own account. Location is used only while you are using the app, for live customer arrival updates and dispatch.
