We have received your letter of September 23 in which you ask for a concession on our terms of payment. In consideration of the very pleasant business relationship we have had with you for several years, we have decided to agree to your suggestion.
We shall, therefore, in future, do business on a draft at 30 d/s on documents against acceptance, and trust that these terms will suit your requirements.
We hope that this concession will result in a considerable increase of your orders and assure you that we shall always do our utmost to execute them to your complete satisfaction.
Our margin of profit is so small that it is impossible for us to make any further concession.——本公司的利润很低微，以致不可能再作任何更进一步的让步。
Wages and the costs of the materials have risen substantially, and we are compelled to adjust our prices to cover at least part of this rise.——由于实际上工资与原料成本已上涨，所以我方不得不调整价格，以至少弥补部分的涨价。
