- We number our cards based on applying for, or approved, not open at the same time. For now, it doesn't seem to matter if you keep your CIPs open, PC them, or close them before going for another. I believe 3 sips is still the most taken here, some are considering 4; but on r/churning, some of the heavy hitters have gone for 5 or 6. You can certainly hold up to 5 or 6 Chase biz cards at a time, but whether it's a good idea to risk opening only CIPs with all those slots is something you should seriously consider. While the CIP does have the highest SUB that makes it very attractive to keep going back to, how many of the same card do you need before it starts to look abusive and Chase shuts you down?
You can diversify your business card portfolio with other Ink cards like the CIC and CIU. Both have "only" 50k UR SUBs, but they have no AF, and have useful bonus categories, especially the CIC with 5x UR at office supply stores if you ever want to consider MS. You could maximize getting bonuses on the other Ink cards by getting the CIC (no support link) for 50k UR SUB, then using the CIC to generate a support link (worth 15k UR) to the CIU for its 50k UR SUB. But before you apply for the CIC or CIU by itself, consider whether you'd maybe want to go for CIP3 for a combined 100k UR (instead of the CIC's only 50k UR SUB, then PC down CIP1 to a CIC in a year, then use the CIC to self-support to a CIU. Again, we don't know whether Chase will come down on self-supportal like Amex, but you do what you can with P1 mode for now.
If you follow our conservative recommendation to space out your Chase apps by 3 months, that's only 4 Chase cards a year. You could do all biz cards, and like I've said there's no hard limit to how many Chase will approve you for. But by the time you get to 3 or 4 Chase biz cards, your odds of approval start getting shaky, not necessarily because of the number of biz cards you have open, but because of the amount of credit line extended to you relative to your business revenue and household income. Chase doesn't want to extend you too much credit (>50% of your household income), and biz card credit limits tend to be lower than personal card limits. So as you open more cards, and Chase keeps approving more credit for you, you may notice the credit limits they approve you for start getting lower. That's why we recommend proactively lowering your credit limits before applying for more Chase biz cards, to increase your odds of approval. But, if you plan to PC a CIP to a CIC later on, then you need to keep at least a $5k CL on that CIP you intend to PC, or have enough credit from other Chase biz cards to move to that CIP you intend to PC to get it up to $5k.
You absolutely should not close any Chase card before you've held it for a year. We recommend just letting the AF post (typically on the 1st day of your 13th month holding the card), and then sending an SM to Chase to request they close or PC the card, and that AF charge will be refunded.
- Chase biz card apps are typically viewed as "harder" to get approved for because most apps go pending before eventually getting approved. Most report getting instant approval on Chase personal cards, and much higher credit limits on personal cards than on Chase biz cards. If you follow our recommendations regarding velocity and credit limits, and are under 5/24, you'll almost certainly get approved for a CIP. If for some reason you don't get approved, you could apply for a Chase personal card immediately or soon after. That's because while Chase biz cards require you to have had no other Chase apps in the last 30 days, approval of a Chase personal card allows for 2 Chase apps/approvals in the last 30 days. So a failed CIP app in the past 30 days won't hurt you going for a Chase personal card within that 30 day timeframe. However, all the other factors like <5/24, <50% household income, velocity, still matter.
- Chase must-haves and good to have: You already have the Chase Freedom for the 5x UR quarterly bonus categories. CSR for the 1.5x redemption on the Chase UR portal. Consider doing a MDD of the CSR with the CSP because you'll be locked out of another Sapphire card bonus for 48+ months. Chase Hyatt card - Hyatt points are very valuable for redeeming award nights, you get a Cat 1-4 free night certificate every anniversary and can earn another Cat 1-4 free night cert by putting $15k spend on it a year, and you get a basic Discoverist elite status. Chase United Explorer card - if you fly United or its an option for you, miles have been devalued but you can still find some deals here and there, the AF is waived the first year and you can PC to a no fee card after that, just holding the card gives you access to expanded economy award availability and a 25% bonus on miles earned on the MPX gift card app. If you fly Southwest or that's an option to you, then definitely some combination of the SW Plus/Premier Priority personal cards and the SW Premier/Performance biz cards to earn Rapid Rewards points and the Companion Pass so your companion flies free with you.
They also love VGF and there are a ton of room tours on that subject. I may be biased

. At least we have a washer now (we even got a small discount because it was slightly dented on the side) and a dryer arriving tomorrow!
