Al comprar un producto o adquirir un servicio lo justo es pagar por él tan pronto como sea posible; lamentablemente hay gente que luego pone pretextos al momento de pagar, como ahorita no tengo dinero, te pago mañana o al rato y al final no quieren pagar por el producto.
Este refrán hace referencia a un trato comercial donde el cliente debe pagar tan pronto reciba su producto y por su parte el proveedor debe cumplir en tiempo y forma con lo acordado, sin pretextos de ninguna de las dos partes.
When buying a product or acquiring a service, it is fair to pay for it as soon as possible; Unfortunately there are people who then make excuses when paying, like right now I don't have money, I'll pay you tomorrow or later and in the end they don't want to pay for the product.
This saying refers to a commercial deal where the client must pay as soon as he receives his product and for his part the supplier must comply in a timely manner with what was agreed, without pretexts from either party.
