Corporate cards for media buyers: top options in 2026
Media-buying agencies facing 2026 ad-platform billing changes are using Slash, Ramp, Mercury IO and Dash.fi for cards and banking to manage higher thresholds and client limits.
Major ad platforms changed billing in 2026 by raising automatic payment thresholds and moving some higher-spend advertisers off card payments and onto monthly invoices or direct debit. Google and Meta charge advertiser cards when spend reaches a platform-set threshold; both platforms can raise those thresholds automatically, and platforms may require invoicing or direct debit for certain accounts.
Agencies that pay client media on their own cards face a cash-flow gap because clients typically pay on net-30 terms while platforms charge as campaigns spend. If a card declines because a per-transaction or monthly limit falls behind a platform threshold, ad delivery can pause and campaigns can re-enter early optimization phases.
Media-buying teams are checking billing settings account by account to confirm which ad accounts still accept card payments. For accounts that still bill by card, agencies note the current payment threshold and set each card’s per-transaction limit above that threshold. Where platforms allow it, advertisers can set a maximum payment threshold to keep charges under a card’s limit; Google does not notify advertisers when it raises thresholds, while Meta provides some controls and has moved some advertisers to invoicing.
Many agencies assign separate cards per client and per ad account and restrict each card to the relevant platform so a single decline does not pause multiple accounts. Providers that combine card issuing with a business checking account let agencies fund card charges and also accept direct-debit pulls or pay monthly invoices from the same balance.
Slash offers a combined business checking and Visa card product aimed at agencies. Customers can issue unlimited virtual cards with individual monthly and per-transaction limits and merchant restrictions. The card limit is the lower of a risk-based maximum and available funds, and it updates in real time as deposits arrive. Slash routes Meta direct-debit pulls to the same checking balance, provides ACH, RTP and FedNow payments, and integrates card spend with common accounting systems. Banking services are provided by Column N.A., Member FDIC, and accounts are open to US-registered LLCs, C-Corps and S-Corps; sole proprietors are not eligible. Slash lists a free tier and a paid tier and offers short-term working capital financing through a partner bank.
Ramp issues unlimited virtual and physical Visa cards with pre-spend policy controls and expense visibility. Its platform can block out-of-policy purchases before they occur and flags exceptions for human review on higher-tier plans. Ramp sets limits using linked cash balances, credit bureau data and other underwriting factors; raising a limit typically requires a formal review or a deposit into a locked Reserve Account. Independent reviews note Ramp often expects substantial US bank balances and primarily US-based operations.
Mercury’s IO card ties limits to balances held at Mercury and to external bank accounts a customer links. The product offers 1.5% cashback, virtual cards for immediate use, and integrations with QuickBooks Online, NetSuite and Xero plus CSV downloads for other systems. Mercury’s IO does not require a personal guarantee or a credit check.
Dash.fi provides a corporate charge card that uses performance-based underwriting to set limits and offers short invoice terms such as Net-1, Net-7 and Net-15. Dash.fi lists higher rewards for ad, shipping and AI spend, unlimited virtual cards and no personal guarantee. The company notes that when a platform moves an advertiser to invoicing or direct debit, card rewards on that platform’s spend no longer apply.
The Federal Reserve’s 2026 Report on Employer Firms shows that 38% of small U.S. employer firms applied for a loan, line of credit or merchant cash advance in the 12 months to late 2025. Agencies and finance teams are tracking account billing settings, payment thresholds and per-card limits to keep campaigns funded and to manage cash flow between paying platforms and collecting from clients.
