What type of financing should Parker seek for warehouse expansion costs?

In considering the type of financing suitable for warehouse expansion costs, bank credit emerges as the most appropriate option. Bank credit typically offers larger amounts of funding at lower interest rates compared to online credit or credit cards, which is critical for significant investments like warehouse expansion. This type of financing is structured and can provide the necessary capital over a longer term, making it ideal for covering substantial costs associated with expanding physical infrastructure.

Furthermore, banks often assess the business’s financial standing and growth potential when offering credit, which can lead to favorable terms if Parker's business demonstrates a viable plan for expansion. This aligns well with the needs typically involved in expanding a warehouse, such as construction costs, purchasing equipment, and increasing inventory, all of which require a stable and substantial source of financing.

The other financing options generally do not provide the same level of financial support or are not tailored for large investments. For instance, online credit and credit card credit often come with higher interest rates and shorter repayment terms, which could impose undue financial pressure on the business if it is not generating immediate returns from the expansion.
