CONTADOR Inteligente-AI tax advisor for builders

Example

Monthly consolidation of mixed revenues: (1) R$300,000 from a construction contract by empreitada with materials (R$120,000 materials); (2) R$200,000 from engineering services without materials. The system classifies each receipt: construction → IRPJ base 8% (R$24,000) and CSLL base 12% (R$36,000); engineering services → 32% (R$64,000) for both. It computes IRPJ: 15% × R$88,000 = R$13,200 plus 10% additional on (R$88,000 − R$20,000) = R$6,800, total IRPJ R$20,000. CSLL: 9% × R$100,000 = R$9,000. PIS/COFINS cumulative: 0.65% and 3% on R$500,000 → PIS R$3,250; COFINS R$15,000. For ISS, it compares “com material” vs “sem material”: invoice with materials in Duque de Caxias uses 3% over R$180,000 (R$5,400) when documents support the deduction; Rio de Janeiro service invoice at 5% over R$200,000 (R$10,000).

Scenario

A contractor is unsure whether to split a contract into phases to maximize ISS material deductions. CONTADOR Inteligente runs side-by-side simulations: (i) single invoice with material deduction; (ii) separate invoices for supply and service; (iii) service-only invoice. It quantifies ISS impact per municipality, updates IRPJ/CSLL presumed bases accordingly, and recommends the lowest-compliance-risk option with required documentation (supplier NF-e, contract clauses, and invoice wording) to withstand a future audit.

Example

When issuing a Duque de Caxias NFS-e (Nota Caxiense), the workflow prompts the user to separate service and material amounts, attach purchase NF-e for the materials, and include contractual references that support deduction. It auto-selects service codes (LC 116 subitems), applies local ISS rates (typically 3%–5%), and flags mandatory retention in public-sector contracts. It generates a clean invoice description and a document bundle (contract excerpt + supplier NF-e XML + calculation sheet) to substantiate the deduction.

Scenario

A company executing a school renovation for the municipality must issue an NFS-e with mandatory ISS withholding. CONTADOR Inteligente prepares the invoice with material deduction, labels it as subject to withholding, and pre-fills the monthly DES. For a Rio capital job without materials, it switches the template, applies the 5% rate, and warns that the entire invoice value is the ISS base; it also stores both invoices and evidence for future cross-checks.

Example

It maintains a calendar keyed to project payroll and invoicing. When a worksite hires labor, it alerts for eSocial events and INSS retention where applicable (e.g., services by empreitada/cessão de mão de obra), and maps withheld taxes (ISSQN, IRRF, CSRF) from public contracts to DCTF/DIRF. It compiles PIS/COFINS totals for EFD-Contribuições and organizes journal entries for SPED Contábil.

Scenario

At month-end, a firm has ISS withheld on a public contract in Duque de Caxias and paid ISS on a private job in Rio. CONTADOR Inteligente reconciles withholdings and payments, produces a municipal DES for Duque de Caxias, summarizes federal withholdings for DCTF/DIRF, and outputs a review checklist (e.g., verify S-1200/S-1210 payroll events in eSocial; confirm supplier NF-e matches material deductions) before management signs off.
