You quote homeowners. ServiceTrade quotes facility managers.
ServiceTrade's whole pitch is asset history per piece of equipment, deficiency tracking, code-compliant inspection reports, and pull-through repair revenue from preventative maintenance — all of which are commercial workflows (source). On a homeowner job, you don't have a facility manager who needs an asset history report. You have a customer who wants to know 'is it $400 or $4,000?'
You need a price. You get a quote-based sales call.
ServiceTrade pricing is custom, with three tiers — Select, Premium, Enterprise — and you have to call sales (source). CurbBid is on the homepage. $399 or $999.
You quote in driveways. They quote in boardrooms.
ServiceTrade's proposal engine is built for multi-asset, multi-page commercial maintenance agreements with labor and parts pricing engines. For a residential plumber sending a 'replace water heater' quote, that's a stadium for a pickup game.
