Comparison Summary

Comparison Summary

We love Mercury as our business banking solution, that said, if you're looking for the best expense management software, you should check out our BILL vs Ramp comparison instead.

Mercury has some expense management features, they just aren't as fleshed out as what BILL S&E and Ramp have out of the box. Even if Mercury had feature-parity, we would personally still use it alongside Ramp.

If you want true expense management, BILL Spend & Expense runs circles around Mercury Bank. BILL lets you create unlimited virtual credit cards with spending limits for each vendor or employee, instantly freeze or adjust limits, and automatically categorize and reconcile expenses with Quickbooks. You get granular control over every dollar and direct fraud prevention thanks to those vendor-specific cards. It's free, has no minimums, and is dead simple to roll out to any size team.

Mercury does a great job at banking basics, sub-account automations, and makes invoicing and bill pay painless. Its interface is smooth, sub-accounts are awesome for cash allocation, and the lack of fees is a big plus. But when it comes to real expense management, like issuing cards to employees, setting per-vendor spend rules, or tracking and reconciling transactions automatically, Mercury just doesn't go nearly as deep.

If expense management is what matters, pick BILL Spend & Expense, no contest. Mercury is a great bank, but for managing and controlling spend at a detailed level, it's not in the same league.
