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 $179/user/mo list — $119/user/mo for the Founding Forty, locked for three years → $7,140/yr for 5 users at the Founding Forty rate billed monthly ($5,950/yr billed annually), everything included. Staff seats are $34 per user, per month for people who log time and do the work they are assigned. 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.
