Los accesoriales son un problema de evidencia antes de ser un problema de transportista.
Sigan una factura de flete, no un camión. El cobro accesorial nace cuando nadie selló el expediente a tiempo. Estima cuánto suele ubicarse entre tu exposición mensual y lo recuperable antes de pagar.
Open calculator →La estadía se disputa con bitácora, no con memoria.
Aviso de arribo, días libres en contrato, bitácora de terminal y factura naviera. Sin eso, el limbo de 90–180 días cobra su impuesto. Estima la exposición antes de que llegue el cobro.
Open calculator →Ops tiene la evidencia. Finanzas paga sin ella.
Día 30 a 60: aparece la deducción. La evidencia existió — en un teléfono, en una cita, en el andén — pero nadie la reunió. Estima lo que suele ubicarse entre exposición y lo recuperable si Ops y Finanzas comparten expediente.
Open calculator →El margen del corredor no está en los kilómetros. Está en los cuatro meses.
El viaje dura un día. Cobrarlo tarda cuatro meses. Estima la fuga anual del gasto de flete (patrón 5–7%) y un rango de retorno si auditas el 100% antes de pagar — estimación de planeación, no garantía.
