Asking the community for tips on increasing credit lines through the banks. Our business goes through ?Chase for banking for pure convenience. Nearest branch is less than a mile from our house. When we started the business last April we were given 3000 limit for our business credit card, and it is still 3000 today. I asked at 6 months, 9 months, and now again at 12 months for an increase of credit limit and have gotten nowhere. Not even a rejection letter. Like our inquiries end up in oblivion. Being on the diesel side everything is much more expensive. We cycled 196k in parts from April to December, so more often then not this is how our day goes for ordering; I'm purchasing parts, paying off the balance, purchasing parts, and again paying off the balance all on the same day. Some engines have injector cost of 450$. Multiply that by 8 and we're above limit so we have to split the purchase. 6.7 Cummstain turbos are 7k so its doing three partial payments to Dodge and 3 balance payoffs to chase before we can have the part in hand. It's just driving me up a wall so I'm seeing if anyone has tips on what to say to increase credit limits for their business. I'd like to keep Chase for the convenience factor, and have never been wronged by them so have no real reason to switch banks.
