Why Amex Charge Cards Have No Preset Limit (Great for Ads)
Half of new Amex applicants are confused about 'no preset spending limit.' Does that mean unlimited? No — but it does mean Amex evaluates each transaction individually based on your history, which is uniquely well-suited to growing ad spend.

How Amex evaluates each charge
Amex looks at: your payment history, your typical spend pattern, the size of the requested charge relative to past charges, time of day, merchant, and Amex's internal underwriting model. A $20K Meta charge on month 2 may decline. The same $20K Meta charge on month 8, after six months of paid-in-full $15K Meta charges, almost always approves.
Why this benefits scaling ad agencies
Traditional credit cards have a hard limit. Hit it and you're stuck until the next statement. Amex charge cards scale with your business. Every successful, paid-in-full charge teaches Amex's model to approve larger amounts. Most agencies report comfortable $50K-$100K monthly spend within 6-12 months.
The 'Check Spending Power' tool
In the Amex app, you can pre-check whether a specific charge will go through. Use it before a big Meta deposit so you don't have a failed charge in the middle of a campaign.
Pay Over Time on charge cards
Amex's Pay Over Time lets you defer charges over $100 into a revolving balance with interest. Useful for occasional cashflow gaps; not a strategy for ongoing ad-spend financing.
Building spending power fast
Tactics that work: pre-pay before large charges, keep payment history flawless, never let auto-pay fail, push charges through gradually (not 10x your prior max in a single try), and avoid Pay Over Time except for emergencies.
Takeaway
No preset limit isn't 'unlimited' — it's 'dynamic, based on your behavior.' For high-volume ad buyers, that's a massive upgrade over the rigid limits of traditional credit cards.
