Money means business. People take money and finances seriously and your startup can use this important aspect of business to continue to brand yourself as professional and reliable, which adds worth to your business brand. At this stage in the game you've purchased your brandable domain name, trademarked it as your business name, and are branding yourself all over the place so hopefully you are starting to see some fiscal results. How you deal with payments can really make or break the respectability of your business brand. When money is handled formally and professionally, your customers will have more faith in the money they are spending, thus adding value to your brand.
