From First Inventory to Long-Range Plan — One Connected System.
For over 25 years, Assisi Software has delivered the tools that forest professionals depend on — from a single cruise plot to millions of acres under management.
Assisi Software was founded with one goal: give forest professionals a single, connected system they can rely on from first inventory to long-range planning. Unlike off-the-shelf tools that force users into rigid workflows, Assisi was designed from the ground up to be open and configurable — built on SQL Server, scriptable in C#, and expandable with custom growth models and reports.
Over 25 years we've grown alongside our users, from independent consulting foresters to large organizations managing timber operations across millions of acres. Every feature in the platform traces back to a real problem in the field. Our development stays closely engaged with the community — we listen to you and user requests go live fast.
Today, Assisi is the platform of choice for operations that need more than spreadsheets but don't want the complexity of enterprise GIS systems bolted together. Powerful where it needs to be. Practical everywhere else.
What We Do
01 — Forest Inventory & Survey
Design surveys, collect field data with Assisi Cruiser, compile cruise results, and maintain accurate, up-to-date inventory estimates using established growth models including ORGANON, FVS, CAGYM, and ACADIA.
02 — Management Planning & Simulation
Schedule harvests by prescription, rotation, or single action. Model thinnings, plantings, and treatments. Run multi-scenario simulations to compare volume, carbon, and cash flow outcomes side by side.
03 — Operations & Financial Tracking
Plan and track on-the-ground activities around sites defined in GIS. Capture income, expenses, and progress toward completion. Build a clear picture of near-term and long-term organizational cash flow.
