When to Choose Mercury

Mercury shines when your e-commerce business starts scaling quickly, maybe after a successful funding round to expand inventory or marketing. If your online store processes high volumes of transactions, needs advanced ways to manage cash from different sales channels, or you’re dealing with international suppliers and want better treasury features, Mercury is a solid pick. Its clean interface and API can help custom track large inventory buys or complex payout structures.

When to Choose Relay

Relay is excellent for e-commerce entrepreneurs who like to keep their finances organized by purpose. You can easily set up separate checking accounts – one for your Shopify ad spend, another for Amazon FBA inventory purchases, one for tax savings, and even one for customer returns. This makes managing cash flow clear, especially if you use a system like Profit First for your online store. The bookkeeper seat also makes it simple for your accountant to access and reconcile transactions from different sales platforms without needing your login details.

When to Choose Novo

Novo is the go-to for new e-commerce sellers, Etsy shop owners, or solo Shopify entrepreneurs. It’s quick to set up and integrates directly with essential e-commerce tools like Stripe, Square, and Shopify, making it easy to track payouts and manage funds from your online sales. It’s genuinely free with no minimum balance, which is a huge plus for businesses just starting out or those with variable sales volumes. While great for solo operations, it's less suited for growing teams or businesses with complex financial needs.

When to Choose Brex

Brex becomes useful when your e-commerce brand is well-established, has a team, and is generating significant operational expenses. Think large ad budget spends on Facebook or Google, multiple employees managing inventory or customer service, or frequent business travel for product sourcing. Its corporate cards and integrated expense management can streamline tracking these costs. For a solo Etsy seller or a new Amazon FBA reseller, Brex's features are overkill – stick with Novo or Relay until your operations scale significantly.

The Verdict

For most new or solo e-commerce sellers, Novo offers the easiest start with crucial integrations. Relay is ideal for online stores focused on clear budgeting and managing cash flow for inventory, ads, and taxes. Choose Mercury when your e-commerce business is highly funded or scaling rapidly with complex financial needs. Brex is for established e-commerce brands with a team and significant expense management challenges. All are free to open, so starting with the best fit now will save you headaches later, even if switching is possible.

How to Get Started

All four banking options allow you to apply online in minutes. You'll generally need your Employer Identification Number (EIN) if you have one, your LLC formation documents (if applicable to your online store), and a government-issued ID. Mercury and Relay might have a short review period, especially for new e-commerce entities. Novo typically offers the fastest approval, getting your new online business bank account ready quickly. Pick the bank that best matches your e-commerce stage right now.

FREQUENTLY ASKED QUESTIONS

Are these real banks or fintech apps?

They are fintech companies that partner with FDIC-member banks to hold your deposits. Your deposits are FDIC-insured, but you are not banking directly with a chartered bank.

Can I use one of these and also keep a traditional bank account?

Yes. Many founders use Mercury or Relay as their primary operating account and keep a local credit union or Chase account for in-person cash deposits.

What if I am not approved?

Mercury and Relay can decline applications, often due to business type or state restrictions. Novo is generally more permissive. If declined, try another option or use a traditional bank while you build account history.
