The Quick Answer
Mercury is often the default recommendation for new real estate brokerages or solo broker-owners. It offers a clean interface, no fees, and works well for quick setup of commission payouts and essential operating expenses like MLS fees. Relay is a stronger fit if you manage a team of agents with complex commission splits or need to track multiple marketing budgets and operating categories separately. Brex Cash makes sense if your brokerage and agents are already using Brex corporate cards for marketing, travel, or office expenses and want a single platform for all spend management.
Side-by-Side Breakdown
Mercury: No monthly fees. No minimum balance. FDIC insured up to $5M through partner banks. Their Treasury product allows you to earn yield on idle cash, ideal for holding future commission payouts or office expansion funds. Strong API for integrating with real estate CRM or accounting software like QuickBooks. Supports ACH, wires, and checks — essential for paying agents, vendors, and receiving funds.
Relay: No monthly fees (Relay Pro at $30/month adds perks). Offers up to 20 checking accounts and 50 debit cards per business. This is perfect for real estate brokerages to create separate buckets for agent commissions, marketing, office rent, tax savings, and owner's draws. Features strong team permission controls, letting you set specific spending limits for agents or administrative staff on different debit cards.
Brex Cash: Free with a Brex corporate card. FDIC insured up to $6M. Offers a high-yield on your operating balance, which is great if your brokerage holds significant cash between large commission clearings. It's tightly integrated with Brex expense management, making it easy to track agent marketing spend or office supply purchases. Note: you cannot open Brex Cash as a standalone checking account without their card product.
When to Choose Mercury
Choose Mercury if you're a new real estate brokerage, a solo broker-owner, or a small firm focused on getting your finances set up quickly. It's ideal for a clean, no-fee business account that works on day one to handle initial operating expenses like MLS fees, CRM subscriptions (e.g., kvCORE, BoomTown), and basic commission payouts. If you need a solid API for custom integrations with real estate software or automated accounting, Mercury delivers. It's also suitable if you want one account for operating cash plus an option to earn yield on idle funds saved for future office upgrades or agent recruitment bonuses. Mercury is often the easiest to open, with approvals typically within 24-48 hours without a branch visit.
When to Choose Relay
Opt for Relay if your brokerage has multiple agents, administrative staff, or a marketing team. It's perfect if you need role-based controls for payments, allowing you to give limited spending access to team members for lockbox purchases, showing supplies, or marketing materials. Relay excels at helping you allocate money into separate accounts by category, which is crucial for real estate. Think dedicated accounts for: 'Agent Commission Pool,' 'Marketing Budget,' 'Office Lease & Utilities,' 'Tax Savings,' and 'Owner's Draw.' This multi-account structure helps track each financial bucket separately, providing clear insights into your profitability and cash flow. It's the closest a fintech gets to Profit First banking for real estate.
When to Choose Brex Cash
Consider Brex Cash if your brokerage or agents are already using Brex for corporate cards. This is common for managing marketing campaigns, open house expenses, virtual staging subscriptions, or travel to real estate conferences. Brex Cash offers a single platform for spend management, reimbursements, and your operating cash, simplifying financial oversight. You'll benefit from yield on your operating balance without having to move money to a separate Treasury account. If you want to see all corporate card spend for agent marketing and office operations alongside your bank balance on the same dashboard, Brex Cash provides that unified view.
The Verdict
For new solo broker-owners or small real estate brokerages, start with Mercury. It offers quick setup for managing commissions and essential operating costs with a user-friendly interface. If your brokerage grows, adds more agents, and you find yourself needing clearer account segmentation for commission splits, agent marketing budgets, or specific funds for expansion, upgrade to Relay. Add Brex Cash if your brokerage and agents are already deeply integrated into the Brex card ecosystem and you want a single platform for all spend management and cash.
