Designed for practices replacing manual, Excel-driven workflows, SegStream reduces study turnaround times from weeks to hours, even minutes, with integrated AI intake. By replacing custom spreadsheets with deterministic engineering logic and live RSMeans cost data maintained by experienced architects and engineers, SegStream enables firms to scale study volume and retain maximum margin without adding headcount. Every report adheres strictly to the 13 principal elements of a high-quality study as defined in the IRS Cost Segregation Audit Techniques Guide (ATG). Key Platform Capabilities - Native RSMeans Cost Data Partnership: Direct API integration of location-adjusted RSMeans construction cost data eliminates manual database updates while ensuring real-world pricing accuracy on every asset calculation. - Deterministic Engineering Property Models: Systematic quantity takeoffs, component classifications, and complete property recreations powered by algorithmic logic developed by on-staff architects and engineers, delivering audit-defensible study production without relying on unpredictable, "black-box" AI guesswork. - Human-in-the-Loop AI Photo Analysis: Automatically parses property site photos to pre-populate property questionnaires, cutting manual data intake by up to 75% while giving senior reviewers full transparency and override control over every AI response. - Automated AI Document Ingestion and Local Redaction: Automatically redacts sensitive client files locally before processing, then uses AI to classify costs across key axes (Direct vs. Indirect, Contractor vs. Client, and MACRS short-life vs. long-life recovery periods) in minutes. - IRS ATG-Compliant Deliverables and Automated Report Assembly: Generates complete, audit-ready engineering deliverables at the push of a button—including customized narrative reports, executive summaries, photo evidence, legal statute citations, and multi-tiered engineering schedules with three separate consistent naming and numbering systems. - Standardized Client Proposal Engine: Generates custom-branded client proposals in minutes using IRS depreciation coefficients and appropriate Bonus Depreciation calendars to provide your clients with the metrics they need to buy, including increased cash flow, ROI, and Lifetime Net Present Value (NPV)—ensuring consistent pricing and professional presentation across your entire practice. - Practice Intelligence and Study Pipeline Dashboards: Real-time visibility into study status, delivery deadlines, firm-wide study volume, and profit economics from a centralized management view. - Enterprise AWS Cloud Infrastructure and Multi-User Collaboration: AWS cloud hosting enables concurrent multi-user project editing without file locks or version-control conflicts, backed by bank-level data security, automatic redundancy, and zero data loss guarantees. - In-App Expert Support and Learning Hub: Direct access to specialty tax engineers via built-in chat (8:00 AM – 9:00 PM ET weekdays), complemented by an interactive AI workflow assistant, guided tours, and a searchable technical knowledge base. Our founders have even been known to drop into the chat from time to time, especially when questions come up after hours or on weekends - come say hi!
