Platform comparison
Some firms assemble a stack: Centerline for construction administration, Monograph for time and fees, GoHighLevel for marketing. Best case, that's three subscriptions, three logins, and three support teams — with your project data re-entered at every hand-off. Here's what it covers, what it still misses, and what it costs.
Pricing
5-person firm example, as of July 2026: Centerline ≈ $9,000/yr (10-project bundle floor) + Monograph ≈ $2,700–3,600/yr (5 seats) + GoHighLevel ≈ $1,164–3,564/yr = ≈ $12,900–16,200/yr. Three separate purchases; two of the three are demo-first.
Unlimited $149/user/mo list — $119/user/mo Founding Firm pricing, locked for life → $7,140/yr for 5 users, everything included. One login. One project record from first lead to final pay app. ARK is in pre-launch; the first-project free tier will be available at launch.
