Field notes
The page models the change from cost-based pricing to pricing after applying recoverable supplier tax credits, with the transition year and split-payment model treated as explicit inputs. Its worked example uses a R$1,000 purchase, R$265 of IBS/CBS, and a 30% markup. The site also describes parameter provenance, versioned calculation records, decimal arithmetic, and validation against 15,156 NCM codes, separating invalid codes from products lacking a tax rule.
