That innovator? Mercury Technologies*, founded in San Francisco 2017 and launched in 2019. In those past 7 years it has grown to serve more than 100,000 businesses and be valued at $4 billion. Mercury has become one of the fastest-moving players in SMB finance by expanding from a simple business bank account into something much bigger.
Over the past year, Mercury has shipped a steady stream of updates across payments, treasury, automation, and even personal banking. The result is a platform that increasingly looks less like a bank and more like a full financial operating system for small businesses.
Here’s what’s new and why it matters to small business owners.
1. Real-Time Payments: Cash Flow Just Got Faster
One of the most important updates is Mercury’s rollout of real-time payments (RTP). Businesses can now receive funds in seconds, 24/7, including payments from platforms like Stripe, Amazon, and Square.
Why it matters:
For SMBs, cash flow timing is everything:
- No more waiting 1–3 days for ACH
- Faster reinvestment into inventory, payroll, or ads
- Better visibility into actual available cash
This closes a major gap between fintechs and traditional banks, where payment speed has historically lagged.
2. Treasury & Yield: Putting Idle Cash to Work
Mercury has continued expanding its Treasury product, aimed at helping businesses earn yield on cash balances.
Recent upgrades include:
- Lowered minimum balance to $250,000
- Same-day access to funds
- Integration with accounting tools like QuickBooks and NetSuite
Why it matters:
Most SMBs still leave cash sitting in low-yield accounts. Mercury is pushing a different model:
- Operating cash stays liquid
- Excess cash is automatically moved into yield-generating portfolios
- No need to manage separate brokerage relationships
This is a direct response to rising interest rates—and a meaningful way for SMBs to generate incremental income without changing operations.
3. Automation & Back-Office Tools
Mercury is also moving aggressively into finance automation, traditionally owned by accounting software.
Recent releases include:
- Bulk transaction categorization
- Receipt forwarding for reimbursements
- Improved auto-transfer rules
- Vendor tracking and payment insights
Why it matters:
For small business owners, finance work is often fragmented:
- Banking in one tool
- Expenses in another
- Accounting somewhere else
Mercury is trying to collapse that stack. The practical impact:
- Less manual bookkeeping
- Faster month-end close
- Fewer errors and missed categorizations
This is especially valuable for lean teams without a dedicated finance function.
4. AI-Powered Search & Insights
Mercury has also introduced natural language search across transactions. Instead of filtering manually, you can now ask:
- “Show transactions over $1,000 last month”
- “Find payments to this vendor this year”
Why it matters:
This is a subtle but important shift toward AI-native banking. For small business owners:
- Faster answers without exporting to Excel
- Easier financial visibility
- Less reliance on accountants for basic questions
Over time, this kind of interface could replace traditional reporting workflows entirely.
5. Mercury Personal: Blurring Business and Personal Finance
The biggest strategic launch is Mercury Personal, now fully available. Key features include:
- High-yield savings (~3%+ APY range)
- Integrated investing (ETFs and Treasuries)
- Joint accounts and shared access
- Global payments and ATM reimbursements
Why it matters:
Many SMB owners already mix business and personal financial decisions:
- Taking distributions
- Managing taxes
- Reinvesting profits
Mercury is leaning into that reality by offering one platform for both business and personal money This reduces friction:
- No more moving money between banks
- Unified view of finances
- Easier cash allocation decisions
It’s also a clear move to increase customer lifetime value.
6. Invoicing, Tax, and Compliance Features
Mercury has added more tools around tax and payments workflows, including:
- 1099 generation and filing
- Mobile invoicing capabilities
- Improved reporting tools
Why it matters:
These features push Mercury into territory traditionally owned by:
- QuickBooks
- Bill.com
- Stripe Invoicing
For SMBs, that means:
- Fewer tools to manage
- Lower software costs
- Simpler workflows across payments and reporting
7. Permissions & Team Controls
Mercury has expanded role-based access and permissions for teams. This allows businesses to:
- Assign roles to employees or contractors
- Set spending limits
- Provide view-only access to accountants or advisors
Why it matters:
As SMBs grow, financial control becomes more complex.
This update enables:
- Better internal controls
- Reduced fraud risk
- Cleaner collaboration with external partners
8. Big Strategic Move: Applying for a Bank Charter
Finally, Mercury has applied for a national bank charter. The goal:
- Become a regulated bank
- Reduce reliance on partner banks
- Gain more control over products and margins
Why it matters:
If approved (and we expect it will), this could:
- Increase trust
- Improve stability
- Enable lending products
For SMBs, it signals Mercury is moving toward becoming a primary financial institution—not just a fintech layer.
The Bottom Line for Business Owners
Mercury is no longer just a business checking account. During the past year, the company has expanded into:
- Payments infrastructure (RTP)
- Cash management (Treasury)
- Automation (expense + categorization)
- Personal finance (Mercury Personal)
- Tax and invoicing tools
The direction is clear:
Mercury is building an all-in-one financial stack designed to replace not only your bank, but your entire finance workflow.
