American Express has a great portfolio of small business cards , and the cards often have large welcome offers. For that matter, a lot of card issuers have been focused on small business cards over the past several years, and you’ll often find that they have better welcome bonuses and benefits than personal cards. For those who may not be familiar with the process of applying for business cards, in this post I’d like to talk about Amex small business cards. What are the popular Amex business cards, what are the rules for getting approved, can you apply with a sole proprietorship, etc.? Amex business card application rules & restrictions Are Amex business cards easy to get approved for? Can you earn Amex business card welcome offers more than once?…
