Comparing Mercury vs Novo

Founders increasingly abandon legacy banks because relationship managers, branch visits, and batch-based systems don’t match how software companies and lean small businesses operate today. You want APIs, predictable fees, fast onboarding, and tools that integrate with your system seamlessly.

​This comparison discusses how Mercury vs Novo support different founder profiles, what you trade off with each, and where both start to show their limits once you move into multi-entity, multi-currency operations.

Key differences at a glance

A comprehensive comparison of Novo vs Mercury is as below.

[Table:1]

Both Novo and Mercury offer separate benefits. If your startup is cash-heavy and needs simpler onboarding, choose Novo. But if you are a tech startup gearing up for high funding, Mercury gives better features.

​Mercury vs Novo: Who They’re Built For

Mercury for venture-backed and tech startups

Mercury targets tech startups that raise capital, hold large USD balances, and frequently transfer money, especially within the US. The product combines

• operating accounts,
  
• enhanced FDIC coverage of up to USD $5 million through sweep banks, and
  
• access to treasury-style yields of up to 3.80% for excess cash, all delivered through a modern dashboard and API.
  

​The platform increasingly revolves around startup funding tools, investor-network products, and support for larger payment volumes and frequent wires, including international transfers.

​Novo for small business owners and solopreneurs

Novo business bank account helps entrepreneurs running lean, revenue-first businesses, including agencies, freelancers, small e-commerce brands, and local or online services. It offers

• Novo bank business checking account with no monthly fee,
  
• no minimum balance requirement,
  
• budgeting via Reserves that allow users to create internal funds buckets for different financial needs, and
  
• Novo funding that provides up to USD $75,000 as working capital.
  

​Where Mercury leans into treasury and funding, Novo leans into cash flow with faster payouts through Novo Boost, same-day ACH options, and invoicing tools that reduce the need for separate billing software. Founders wanting easier and faster cash flow often choose Novo. But if you're tracking ownership stakes, monitoring how long your money will last, and paying people in different countries, Mercury fits better with how venture-funded companies handle their finances.

​Eligibility and onboarding for Mercury vs Novo

Mercury Bank's business account generally requires a US-registered corporation or LLC. It doesn’t support certain entity types, such as sole proprietors or trusts, which immediately disqualify some early-stage founders.

Novo accepts a broader range of structures, including sole proprietorships, LLCs, corporations, partnerships, and many nonprofits, making it more flexible for small or informal setups.

​For US founders with standard tech entities and clear ownership, Mercury’s onboarding happens fully online but often requires rigorous documentation for ownership, source of funds, and industry risk. International founders often face additional friction on both platforms, particularly around address verification, identification, and higher-risk categories such as financial services, crypto, or certain marketplace models.

​Cash management and security features

Mercury Treasury vs. Novo Boost

Mercury offers treasury functionality and a vault model that lets you keep idle cash in accounts with expanded FDIC coverage and, for larger balances, in money market funds managed by established asset managers. You can protect your account balance using Mercury, which can easily exceed standard insurance limits of USD $250,000 while generating some yield without making a separate brokerage relationship.

Novo’s pros lean more towards cash acceleration rather than yield. Novo Boost pulls Stripe payouts into your account within hours instead of the usual multi-day delay, and Express ACH supports same-day transfers, compressing the time between revenue recognition and actual usable cash.

If shaving days off collections matters more to you than earning interest on balances that don’t stay high for long, Novo is the right platform that offers you instant capital to keep your operations running non-stop.

​Spend limits and virtual card management

Mercury provides both physical and virtual debit cards, with the ability to assign cards to team members and manage spend centrally. For a scaling team, having card-per-user structures makes it easier to separate founder, leadership, and operational spend and to shut down or adjust cards quickly as roles change.

​Novo issues a business debit card and supports virtual cards that are merchant and subscription control-oriented rather than deep expense policy engines. Both platforms enforce daily limits and network-level caps, and if you regularly run large advertising, inventory, or travel bills through a single card, you’ll want to confirm those limits before a major campaign or launch.

Novo vs Mercury: ​Accounting, Integrations, and Automation

QuickBooks and Xero integrations

Both Novo vs Mercury integrate with popular accounting platforms such as QuickBooks and Xero, allowing transaction data to sync automatically into your ledger.

​The main difference is that Mercury’s API-first works best for teams that are already automating bookkeeping workflows, while Novo’s audience is more likely to lean on the out-of-the-box connection and manual review.

​Automated invoicing vs. developer-first API

Novo includes built-in invoicing that lets you create and send invoices, connect payment processors like Stripe or others, and receive card or ACH payments directly into your account. If you don’t want to manage separate billing software and prefer to keep cash-in operations as consolidated as possible, Novo will be useful.

​Mercury, by contrast, emphasizes a developer-friendly API that allows you or your team to programmatically read balances, create payments, and integrate banking data into internal tools or reporting. For tech startups, this enables custom workflows like automated vendor payment runs, internal dashboards for cash and balance, or integration with proprietary systems.

Customer support models

Many founders have faced a recurring pain point across both platforms: customer support. Mercury and Novo’s support teams rely heavily on email and chat, and real-time phone access is limited or reserved for specific scenarios. So, you may expect a delay in response as live conversation is scarce. This can bump into your business when you’re chasing a six-figure wire, handling a time-sensitive vendor payment, or resolving a flagged transaction.

​Founder reviews across forums consistently cite teams moving issues around without clear ownership. When evaluating either option, factor in how much you rely on same-day problem resolution, especially if your business model involves large, time-critical transfers.

​Global Payments and Pricing Models

Mercury’s USD focus and international wire fee structure

Mercury primarily operates in USD, so while you can send international payments in other currencies, your banking remains US-based. While Mercury often markets outgoing wires as low-fee, intermediary and recipient banks can add extra costs and delays, especially in less common markets.

Many US startups pay international contractors in USD or a few currencies and put up with some friction. But as payment volumes increase, the absence of local accounts or in-country payment systems can make vendor payments and payroll harder to manage and more costly.

​Novo’s Wise integration and currency conversion

Novo leverages third-party services like Wise to handle international transfers and currency conversion. You initiate transfers from your Novo business banking account, but FX and cross-border payment systems are run by Wise, with its own fee and rate structure.

The benefit is access to a mature FX platform without Novo having to build cross-border capabilities from scratch. The trade-off is that you’re now depending on two entities, Novo and Wise, and need to understand both sets of fees, processing times, and potential failure modes.

​Novo Bank vs Mercury: Handling non-USD operations

Mercury bank vs Novo, neither is a replacement for a global transaction bank when you start needing local accounts in EUR, GBP, SGD, or other currencies.

​Once you’re opening subsidiaries in multiple regions, running local payroll, or managing tax exposure across borders, you’ll likely need additional banking partners or specialized fintechs for multi-currency accounts. Treat Novo and Mercury as strong US operating bases, not comprehensive global banking solutions. This is where global-first platforms like Aspire enter the picture.

If your future plan is to expand cross-country, then switching to a platform that supports global payments is a smarter choice. Read more about Aspire’s Global Payments for more details.

​Mercury vs Novo: Pricing differences

Both platforms market “no monthly fees” and low or no-cost everyday banking, so no monthly maintenance, no minimum balance requirements, and free standard ACH transfers. This is accurate on paper, but functions like FX markups, international wire fees, potential intermediary-bank charges, and ATM or cash-handling expenses are not free.

Mercury tends to charge minimal fees on domestic operations, but will apply 1% FX or cross-border costs when you operate internationally. Novo is the low-cost business checking account that rebates up to USD $7 of annual ATM fees and keeps most core actions free. But you may pay Wise 0.4-1.9% fees, depending on the country, for international transfers, and face indirect costs if you still need other tools for advanced treasury. Check your monthly international wires and ACH volume, as domestic transfers are free, but international FX charges hit different. Either is good if your business only operates domestically in the US. But if you are planning to expand overseas, be ready for the additional charges.

​Conclusion

The Mercury vs Novo decision is really a decision about how long you want your first banking setup to last.

• If you’re raising institutional capital, holding large USD balances, and building an internal finance stack, Mercury’s treasury, coverage, and API tilt the balance in its favor.
  
• If you’re running a lean, profitable business where cash-in speed and operational simplicity matter most, Novo’s invoicing, Boost, and straightforward account structure often align better.
  

​Many founders start life on Novo for flexibility and ease of setup and later migrate to Mercury once they formalize the entity, raise, or need more advanced controls.
