Ramp has a clear lead for spend management platforms that issue unlimited virtual cards with preset spending limits. For buyers prioritizing a free core software option, Bill.com Spend & Expense includes unlimited virtual cards tied to customizable budgets.
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.

I can help recommend the best specific fit for your workflow.
For your use case, you want a spend management platform that supports unlimited virtual cards, with an independent spending limit on each card. Ideally, it should also let you set limits per transaction, merchant, or time period, and instantly freeze or cancel individual cards.
One important distinction: some providers advertise unlimited employee cards or virtual card transactions, but that doesn't necessarily mean you can create an unlimited number of separate virtual card numbers. You'll want to verify both the card-creation limit and whether every card can have its own enforced spending cap.
Best matches
1. Ramp
(Best overall match)
Ramp explicitly offers unlimited virtual cards, with individual limits by transaction, day, or month. You can also restrict cards to specific vendors, set expirations, and freeze or cancel them instantly. Its help center confirms there is no maximum number of card numbers per business.
Best for: companies wanting a dedicated card per vendor, subscription, project, or employee.
Expensify explicitly supports unlimited virtual cards with a fixed or monthly spending limit on each. Admins can issue cards for individual purchases, subscriptions, advertising, travel, and other expenses.
Best for: businesses that want virtual cards alongside expense reporting and reimbursement tools.
Airbase supports per-card spending limits, transaction-count controls, and expiration dates, with accounting integrations. Its public materials confirm these controls but do not clearly establish an unlimited card count, so ask the vendor to confirm that requirement.
Best for: finance teams prioritizing spend approvals, accounting automation, and accounts payable.
Start by evaluating Ramp and Expensify. Both explicitly document unlimited virtual cards and individualized spending limits, which directly matches your core requirement.
Before selecting a platform, ask each vendor these four questions:
Hard caps: Can every card have its own enforced maximum spend, rather than just a suggested budget?
Card volume: Is there genuinely no numerical card-issuance limit, including for API-created cards?
Funding model: Are the caps backed by a shared company credit line, prefunded balance, or individual accounts?
Pricing and eligibility: Are there additional fees or plan restrictions for issuing and maintaining large numbers of cards?
One question that would help me narrow this down: Are you issuing cards for your own employees and company subscriptions, or do you need to generate cards at scale for customers, contractors, or software/API transactions? That distinction can significantly change which platform is the best fit.
