Generally, small to medium-sized businesses can apply for a working capital loan. Lenders may require businesses to have been operational for a certain period and may evaluate the business's creditworthiness and financial health.

The terms and interest rates for working capital loans vary widely depending on the lender, the size of the loan, and the credit profile of the business. Typically, interest rates can range from 5% to 30%, and repayment terms can be as short as a few months to several years.

The speed of funding for a working capital loan depends on the lender and the application process. Some lenders can provide funding within 24 to 48 hours, while traditional banks may take several days to weeks to process the application and disburse funds.

The documentation required may vary by lender but generally includes financial statements, tax returns, a business plan, bank statements, and details about the business's cash flow. Some lenders may also require personal credit information from the business owner.

While working capital loans are intended for short-term operational expenses, it's important to use the funds wisely. They can typically be used for payroll, inventory purchases, rent, and other immediate costs. However, using them for long-term investments or large capital expenditures may not be advisable. Always check the lender's guidelines for specific usage.
