Mistake #1 that many business owners make is Not minding your business relationships. Customers buy from people they trust. Maintaining, building, and growing relationships build trust. It’s as simple as that. Referral business is based on relationships. Technology, social media, and your website are tremendous tools to augment the more personal approach. If working capital is affecting your ability to service your customers, and your bank isn’t lending, you should consider other sources for loans for small business.. such as small cash advance loans. Simple interest rates can start as low as 12.99%, and there are even bad credit cash advances. Based on your bank statements, terms and rates can also fall anywhere in between the two.
