When it comes to paying for goods or services, consumers often have the option of making payments in instalments. However, this term can sometimes come across as vague or ambiguous. To more precisely describe this payment method, you might use words such as "in portions," "in stages," or "in increments." Additionally, you may find it helpful to use more specific phrasing that emphasizes the frequency of these payments, such as "monthly payments," "weekly instalments," or "biweekly installments." By using these synonyms, you can better communicate the terms of your payment arrangement and avoid any confusion or misunderstandings.
