WallesterTop pickBrexRampRevolut BusinessJeevesWallester Business and Ramp both offer genuinely free plans at $0/month. Wallester includes 300 virtual cards, unlimited physical cards, unlimited users, and multi-currency IBANs. Ramp is free for all company sizes with unlimited physical and virtual cards plus 1.5% cashback. Brex has a free tier but requires qualifying funding or revenue. Revolut's Starter plan is free but limits transactions.
Corporate cards like Wallester, Brex, and Ramp do not require a personal guarantee — liability stays with the business entity. Traditional business credit cards from banks typically do require a personal guarantee, which puts your personal credit and assets at risk if the business defaults. For startups and LLCs wanting to protect personal assets, a corporate card without a personal guarantee is strongly preferred.
Corporate cards (like Wallester, Brex, Ramp) are issued to the company entity — no personal guarantee required, liability is corporate. Business credit cards (like Chase Ink or AmEx Business) report to personal credit bureaus and require a personal guarantee. Corporate cards typically offer better expense management software, real-time controls, and multi-card issuance. Business credit cards often have richer rewards programs.
More than you think. Best practice: one card per SaaS subscription, per employee, and per recurring vendor. A 10-person startup with 20 SaaS tools could need 50+ virtual cards. This makes it easy to cancel subscriptions, track spend by category, and prevent card-skimming fraud. Wallester's 300 free virtual cards cover most US startups comfortably through their growth phase.
Wallester, Brex, Ramp, and Revolut all offer direct QuickBooks Online integrations. Ramp has the deepest integration with automatic categorization and line-item sync. Brex connects to QuickBooks and NetSuite with automatic reconciliation. Wallester integrates with Xero, QuickBooks, and NetSuite, plus offers a REST API for custom setups. For NetSuite specifically: Brex and Wallester have the strongest integrations.
The only platform offering $0/month with 300 virtual cards, unlimited physical cards, unlimited users, and multi-currency IBANs in 10 currencies including USD. No personal guarantee required. Available across the US, EEA, and 40+ countries worldwide.
