Sin embargo, en el segundo caso hay otro matiz, a saber:

...the amounts paid are entered on the spreadsheet against the relevant invoices.

Las cantidades pagadas se anotan en la hoja de cálculo relacionándolas con las facturas pertinentes. Es decir, registrándola en la línea o cuadro que corresponda a la factura.

o "al presentar" las facturas correspondientes

Claramente se refiere al monto abonado que se aplica al pago de determinada factura. Para el segundo caso utilizaría "en pago de las facturas correspondientes"

La palabra "against" is used in all sorts of payment policy; to name but a few, you may indicate in your invoice:
* payment against documents;
* payment against receipt of goods;

In this case, the payment will have to be settled not at 30, 60 days or whatever, but rather upon receipt of the invoice. Usually, in this case, the settler is aloud a small discount for prompt payment, i.e., 2 or 3%, it depends.

Hope it helps you

I see some \"disagreements\" above, but believe me - you are wrong. \"Presentation of the invoice\" is of course in such cases a metaphor. The invoice may come by mail, to be handed over, or simply be advanced by fax or e-mai.

Imagine, for instance, that the arrival of the goods absolutely depends on the advanced payment, because either it is a new supplier or any other situation. To get it all quicker, you request that invoice is sent through one of these means, so that you may send cheque or make bank transfer at once.

You would understand if a whole factory would depend from that product for some reason.
