The maximum small business loan funding amount differs among various banks and also depends on your company credit profile (revenue size, industry, cashflow position etc.).
Most banks’ maximum financing amount granted to SMEs range between $300K to $500K. However, it is exceedingly hard to secure the maximum amount unless the company has close to perfect credit profile. If your main bank is not able to meet your requested financing amount, you can also apply across other banks concurrently to maximize the financing amount you’re targeting.
