Selk is a job-management app for small contractors and service businesses with crews of 1 to 10: electricians, plumbers, HVAC, handymen, painters, landscapers, cleaners and more. It was built by a working electrician in Houston, Texas. One flow from start to paid: new job, estimate, schedule, crew does the work, invoice, paid. Send estimates in a minute from your own price book as a PDF by text, email or WhatsApp. Take card payments through your own Stripe account (Pay Now on invoices, deposits on estimates) with no added Selk fee, or record cash, Zelle and check by hand. Schedule by day with the weather forecast, repeat jobs, and saved crews. Workers get a free app with today's jobs, addresses, clock in/out and photos, and never see prices. Smart arrival alerts tell the owner when a worker reaches the job, with no live GPS tracking. Also includes QuickBooks Online sync, a booking page, van stock, offline mode and six languages. Works on iPhone and on any computer. Everything included, no add-ons: Solo $29/month, Contractor $79/month (up to 5 workers), Contractor 10 $129/month (up to 10 workers). 14-day free trial.
