Short term finance refers to additional money a business requires for periods under one year. Common sources of short term finance include bank overdrafts, which allow businesses to draw more money than in their accounts up to a limit; trade credit, where suppliers allow purchases to be paid for over time; factoring, where accounts receivable are sold to firms who pay upfront and collect payments; credit cards for employees' business expenses; leasing equipment instead of purchasing; and bank loans repaid in installments over short terms.
