Our own appraisal platform
Taxatie Bureau Jozef Laclé works on SIGMA-CMS — appraisal software developed in-house by Architect & Technologist Greg Laclé (patent pending), built around the way a valuation is actually produced in the field.
Our own appraisal platform
Most appraisal reports are assembled by hand, which is exactly where inconsistencies enter. SIGMA-CMS captures the inspection on site in a structured form, carries that data through the analysis untouched, and checks the finished report against itself before it can be issued. The result is a valuation that is faster to produce and considerably harder to get wrong.
SIGMA-CMS is our internal instrument, not a substitute for judgement. Every value is determined and signed by the appraiser.
SIGMA-CMS · field to file



- 01
Structured field capture
Rooms, dimensions, materials, installations, condition and photographs are recorded on site in a fixed structure, so nothing depends on what is remembered afterwards.
- 02
Evidence-linked comparables
Every comparable and adjustment stays attached to the figure it supports, so any number in the report can be traced back to what justifies it.
- 03
Automatic consistency checks
Areas, values, methods and totals are cross-checked against each other. Contradictions are surfaced before the report leaves the office, not after.
- 04
Complete, auditable reports
The report is generated from the record itself — method, evidence, assumptions and conclusion in one document, consistent from first assignment to last.
