Why solo plumbers and HVAC techs leave Housecall Pro.
Housecall Pro was designed around a specific customer: the franchised or franchise-style home service brand running 10+ trucks. That shows in every product decision they've made since. Marketing Pro ($150–250/mo on top of your subscription) sells postcards, Google reviews automation, and Yelp ads. Sales Proposals is a separate $99/mo add-on. Recurring Service Plans is locked to the MAX tier ($249/mo before per-user fees). For a franchise this stack makes sense. For a solo plumber doing 12 jobs a week, it's $300+ of monthly software for tools you never asked for.
The bigger structural issue is how hard Housecall Pro makes it to downgrade. Threads on r/sweatystartup and r/HVAC describe the same pattern: a tradie signs up at Basic ($79/mo), gets upsold to Essentials ($189/mo) for one feature they actually need, then realizes 90% of the rest is sales-team friction they don't use. Trying to roll back to Basic involves losing data fields, customer history annotations, and (on some plans) the ability to keep their existing customer list intact. Once you're in, the cost of leaving grows faster than the cost of staying.
Decker takes the opposite approach. There is no Marketing Pro upsell to design around. There is no Sales Proposals tier. There are no franchise-targeted features bolted on at every renewal cycle. The product is built for one specific customer: the solo plumber, electrician, HVAC tech, handyman or locksmith — and the small teams (3–10 people) that grew out of them. Everything in the product is something a working tradie actually uses on a Tuesday afternoon between jobs. $19/month Solo, $39/month Pro, locked for life as a founding customer, and the same total whether you have 1 user or 10.
The other shift: WhatsApp instead of Housecall Pro's customer messaging app. Your customers already use WhatsApp. They don't want to download "the Housecall app" to see their invoice. Decker sends the message into the WhatsApp conversation your customer is already in — no app install, no SMS fees, much higher reply rates. That's the structural piece Housecall Pro will not change because its franchise customers want their own branded messaging surface. Solo tradies don't.
