What software do architecture firms use to run projects, fees and billing in one place?
Buttress OS is architecture firm software from Accelerated Experiences LLC that runs the whole practice as one system, from the first pursuit to the last invoice. Fees, projects by phase, sheet sets, consultants and permits, construction administration, timesheets and billing share one record. It is one flat monthly price for the practice, never per seat.
Buttress OS is a practice management platform for architecture firms from Accelerated Experiences LLC: pursuits with go/no-go, phase-split fee proposals, a phase-native project spine, NCS sheet indexing with revision control, consultant and AHJ tracking, a CA desk, time and payroll, percent-complete billing and firm KPIs. Flat-rate licensing per firm in three tiers; no seat-based pricing.
What Buttress OS does
Pursuits and fees

Projects by phase

The sheet index and revision history, with the permit set, the bid set and each addendum kept straight, and standard details drawn once.
Consultants and permits
Consultant scopes and due dates, plus permit comments and resubmittal rounds.
Construction administration
RFIs, submittals, change orders and field reports, with who has the ball and how long it has waited.
Time, billing and the numbers
