Aside from clearly setting out the total amount payable, and the currency and country of the currency, e.g. USD, it is important to determine terms such as the amount payable on closing, the form of payment (cash, wire transfer etc.), dates for payment of installments, any vendor-take-back loans or promissory notes, and the interest rate on installments or delayed payments and loans. The clause can also specify the source of payment (e.g. by loan from a financial institution, or by amount for each purchaser if there are multiple purchasers) and even which bank branch or specific bank account may receive payment. If payment is not made in an acceptable form, then it may not count as ‘payment’ under the agreement.
