Positioning guardrails
Best for
- US trucking and logistics fleets (local, OTR and mixed) that want fuel discounts plus hard spend controls
- Small fleets and owner-operators needing fuel credit without a hard credit check
- Freight brokers and factoring companies that pay carriers and drivers instantly
- Mixed-fuel fleets adding EV charging alongside diesel and unleaded spend
- Fleet managers consolidating multiple fuel cards, reimbursements and manual reporting
Ideal size: 1–500 employees people · US fleet operator, carrier, broker or factor with at least one vehicle or driver to pay
Not for
- Businesses outside the US — card issuance, discount network and bank partners are US-based
- Non-fleet companies looking for a general corporate expense card
- Teams expecting a standalone SaaS subscription with published per-seat pricing
- Buyers wanting fleet telematics, dispatch or TMS software — AtoB integrates with those rather than replacing them

Frequently asked questions
How much does AtoB cost?
AtoB publishes no subscription or per-seat price; the pricing page is an application form that says only "simple, affordable pricing". Revenue comes from negotiated fuel discounts and card interchange, plus a stated 1% fee on instant transfers to drivers. No card or per-transaction fees are stated, and all cards are subject to credit approval.
How quickly can a fleet go live with AtoB?
AtoB advertises a five-minute online application and describes the programme as fast to deploy: set spend rules in the dashboard, connect a telematics provider, equip drivers with the AtoB Driver app and track transactions in real time. Limits move quickly — one customer reports a $2,500 limit approved in ten minutes. Card delivery and credit-decision timing are not stated on the vendor pages.
Is AtoB a bank, and how does fleet credit work?
No. AtoB says it is not a bank but maintains wallet accounts at an FDIC-insured bank, and cards are issued by Celtic Bank or Community Federal Savings Bank under a Mastercard licence. AtoB offers both credit and prepaid spend cards, sizes credit to fuel usage and business revenue, says the application requires no hard credit check, and reports repayment to business credit bureaus such as Experian.
What protection does AtoB offer against fuel fraud?
AtoB advertises a $250,000 fraud prevention guarantee, subject to eligibility and fleet size, contingent on connecting the account to vehicle telematics. Cards can be locked by default and unlocked only by an authorised driver or admin; with telematics, AtoB validates the vehicle and merchant GPS location and can adjust authorisations against tank level. Admins also set per-transaction, daily and weekly limits, operating hours, merchant whitelists and category restrictions.
Does AtoB support EV and mixed fleets?
Yes. AtoB says it is purpose-built for mixed-fuel and electric fleets: one card covers high-flow diesel, gas and EV charging, reporting across ICE and EV usage sits in a single dashboard, and fleets can reimburse employees for home charging through the platform. EV charging works anywhere Mastercard is accepted.
Can AtoB replace our fleet management or telematics software?
No. AtoB is a payments and spend-management layer. It integrates with telematics providers — for example sending IFTA-eligible transaction data to Samsara to automate fuel tax filing — but it does not provide telematics, dispatch or TMS functionality. Fleets should keep their existing telematics and fleet systems and connect AtoB to them.
