Where an advance payment is made equal to, say 10% of the contract price, it is quite common for the contract to state that the regular interim payments which are made as the contract progresses will be reduced by 10% until the advance payment has been recovered in full from those deductions.
Cuando un pago anticipado asciende a digamos el 10% del precio del contrato, es muy común que el contratista establezca pagos parciales en forma regular, que son efectuados a medida que avanza el contrato y serán rebajados de a 10%, hasta que el pago anticipado haya sido recuperado totalmente de esas deducciones.
