Dashboard Reference

Transaction Details — General Information, Taxes Breakdown & Counterpart

The main transaction screen contains General Information (IDs, amounts, currency), Taxes Breakdown (tax name, taxable amount, withholding type, and amount), and the Counterpart panel (legal name, tax registration number, and address of the seller).

📸

Transaction Details — Items

The Items section shows each line item with its service category code, net amount, and total (final amount including taxes).

Notes

Counterpart in the dashboard corresponds to the seller or service provider operating through the platform.
Withholding fields (ISR, VAT, IEPS) are only required when the intermediary is responsible for retaining taxes on behalf of the seller. When no withholding applies, the Withholding Type column will show -.
CURP is only applicable for natural persons (individuals), not legal entities.
VAT and final amount are calculated automatically by Brinta and do not need to be sent in the request.
