Coil is booking and business software for tattooers and tattoo shops. Every tattooer gets their own site, built from their photos, at name.coil.tattoo or their own domain. Clients send a booking request with reference photos, placement, size and budget, and pay the deposit by card, Venmo, Cash App, Zelle or PayPal. Consent forms are signed on the client's phone and follow state rules. Reminders and aftercare go out by text from each tattooer's own number, and Instagram booking DMs get answered with the booking link. Shops get a front desk, walk-ins, booth rent, commission payouts and one page with every chair. Coil takes no cut of deposits, payments or tips: $59 a month solo, $49 a chair in a shop, and chair nine and up are free.
