Ramp explicitly advertises unlimited virtual cards. Its documentation also says there is no maximum number of physical or virtual card numbers per business.
Each card can have its own hard spending controls, including:
Per-transaction maximums
Daily/monthly/other recurring limits
Vendor-specific restrictions
Merchant-category restrictions
Expiration dates
Single-use cards
Real-time freeze/cancellation
Transactions exceeding the configured limit are automatically declined.
Brex also supports unlimited virtual cards with custom limits and lock dates, and its spend controls can be tied to merchants, categories and specific spending policies.
3. BILL Spend & Expense
BILL is particularly interesting if you want budget-enforced cards. BILL states that you can create unlimited virtual cards, with spending tied to assigned budgets; a card without available funds won't work.
4. Airbase
Airbase offers unlimited virtual cards and lets you set controls based on amount, time period, and number of transactions, along with one-time, recurring, and vendor-specific cards.
My shortlist: If your exact requirement is “create an unlimited number of virtual cards, each with a hard pre-set spending ceiling”, I'd start with Ramp, then compare Brex and BILL based on your accounting/AP requirements.
If you tell me your company size, approximate monthly card spend, and accounting system (QuickBooks, NetSuite, Xero, etc.), I can do a deeper Ramp vs. Brex vs. BILL vs. Airbase comparison, including pricing, approval workflows, funding requirements, rewards, and integrations.
Several top-tier spend management platforms specialize in issuing unlimited virtual corporate cards with customizable, pre-set spending limits (such as single-use limits, monthly caps, or vendor-locked restrictions).
The leading options on the market include:
Ramp – Widely regarded as a premier spend management choice. It lets you issue unlimited virtual and physical cards with granular custom limits (per transaction, daily, monthly, or annual) that are automatically enforced at swipe. It is free to use on its core tier and offers robust accounting automation.
Brex – Built for scaling and global teams, Brex offers unlimited virtual cards with dynamic, policy-based spending limits. You can lock cards to specific vendors or spending categories, and it integrates deeply with major ERPs.
BILL Spend & Expense (formerly Divvy) – Excellent for small-to-midsize businesses prioritizing strict budget enforcement. It allows you to create budget-locked virtual cards with exact pre-set limits where exhausting the budget automatically locks or deactivates the card.
Navan Expense – An all-in-one travel and expense platform that lets companies issue unlimited virtual cards globally for recurring or one-time use, embedded with strict policy controls before any purchase happens.
Airwallex – A strong option if you operate internationally, offering unlimited virtual corporate cards with zero software user fees and strict pre-set merchant/spend caps.
To help narrow down the best fit, let me know:
Do you need international/multi-currency support or strictly domestic US spending?
Are these cards mostly for software subscriptions/vendors, employee travel , or general team expenses?
What accounting software (e.g., QuickBooks, NetSuite, Xero) do you need it to sync with?
