Online Business Banking Options for Research Relay LLC¶
Research conducted February 2026. Research Relay LLC is a California single-member LLC selling RUO (Research Use Only) peptides and research chemicals via e-commerce. Registered agent: Northwest Registered Agent.
Executive Summary¶
For a California LLC selling legal RUO research chemicals online, the banking landscape presents meaningful challenges. Most fintech banks are designed for SaaS/tech startups, and research chemicals sit in a gray area that triggers extra scrutiny even though the business is fully legal. After evaluating six online banking platforms, Mercury emerges as the primary recommendation with Bluevine as the backup, subject to the caveats detailed below.
Bank-by-Bank Analysis¶
1. Mercury¶
Website: mercury.com Banking Partners: Choice Financial Group, Column N.A. (Members FDIC) FDIC Coverage: Up to $5M via Insured Cash Sweep
Signup Process¶
- 100% online application, approximately 10 minutes
- Approval typically within 1-3 business days
- Required documents: Articles of Organization, EIN letter from IRS, government-issued photo ID for beneficial owner(s)
- Mercury asks about your target customer, transaction types, and links to professional articles or announcements about the business
Address Requirements¶
- Legal address: Must be a physical U.S. address. Official policy states registered agent addresses, PO boxes, and UPS boxes are not accepted as the legal address.
- In practice: Some users report success using a registered agent address (particularly non-US founders), but Mercury tightened enforcement significantly in 2025. Multiple rejection reports exist for registered agent addresses.
- Recommendation: Use your personal home address as the legal/business address. List Northwest Registered Agent only in formation documents where required by the state.
Crypto Policy¶
- Mercury explicitly supports crypto/web3 startups as banking clients
- Purchasing crypto on regulated exchanges (Coinbase, Gemini) from a Mercury account is allowed
- Mercury accounts can only hold fiat -- no crypto custody
- Mercury cannot bank Money Services Businesses (MSBs) registered with FinCEN
- Using the account primarily for crypto buying/selling may trigger closure
- For our use case (accepting BTC payments via a processor that converts to USD): This should be acceptable as long as BTC-to-USD conversion happens through a third-party payment processor (e.g., BTCPay Server with a conversion service) and Mercury only sees incoming USD deposits. Mercury is not handling any crypto directly.
Research Chemicals / High-Risk Tolerance¶
- Mercury's restricted industries list includes: adult entertainment, cannabis, internet gambling, and money services businesses
- Research chemicals and supplements are not on the restricted list
- Mercury explicitly markets to e-commerce businesses
- However, Mercury has undergone waves of account closures for businesses deemed high-risk. Communications around closures are vague ("breach of Terms of Service").
- Mercury cut ties with partner bank Evolve Bank & Trust in March 2025, which triggered some closures
- Applied for its own national bank charter in December 2025
Fees¶
| Item | Cost |
|---|---|
| Monthly fee | $0 (free tier) |
| Paid plans | Starting at $35/month |
| Account minimums | None |
| Domestic USD wires (send/receive) | Free |
| International USD wires | Free (standard); $15 for premium "OUR" processing |
| Currency exchange | 1% fee |
| ACH transfers | Free |
| Credit card | IO Mastercard, 1.5% cashback |
Accounting Integrations¶
- Native: QuickBooks Online, Xero, NetSuite
- Zoho Books: No native integration. Available via Zapier, Pipedream, or Appy Pie Automate. CSV export is always available as a fallback.
- Mercury offers AI-powered GL code assignment and transaction categorization
Pros¶
- No fees on domestic/international USD wires
- Up to $5M FDIC insurance
- Crypto-tolerant (not crypto-hostile)
- Strong e-commerce feature set (Shopify, Amazon, Stripe integrations)
- Free business checking with no minimums
- Working capital loans available for established e-commerce businesses
Cons¶
- Registered agent address officially not accepted (use home address)
- History of abrupt account closures with vague explanations
- No Zoho Books native integration
- Not a bank (fintech) -- regulatory uncertainty during charter application
- Email-only customer support can be slow during account issues
2. Relay¶
Website: relayfi.com Banking Partner: Thread Bank (Member FDIC) FDIC Coverage: Up to $3M via deposit sweep program
Signup Process¶
- 100% online, approximately 10 minutes
- Approval within 1-2 business days
- Required: EIN, Articles of Organization, government-issued photo ID, selfie verification
- Requires a valid U.S. phone number and email
Address Requirements¶
- Requires a physical U.S. address for personal address (no PO boxes or virtual mailboxes)
- Relay reportedly wants a "real U.S. office," lease agreement, or business utility bill in some cases -- stricter than Mercury
- Registered agent address: Likely rejected. Relay's requirements are more stringent than Mercury's for business address verification.
Crypto Policy¶
- Cryptocurrency businesses are explicitly prohibited. Relay cannot support any business dealing with "provisioning and exchanging cryptocurrency."
- This extends beyond crypto businesses -- it is unclear whether simply receiving converted BTC-to-USD deposits would trigger a flag, but the blanket prohibition makes Relay risky for any business with crypto-adjacent activity.
Research Chemicals / High-Risk Tolerance¶
- Relay's prohibited list includes: cryptocurrency, firearms/weapons, credit repair, privately owned ATMs, money services, unlawful internet gambling, and cannabis
- Research chemicals are not explicitly listed as prohibited
- However, Relay's conservative stance (explicit crypto ban, stricter address verification) suggests lower tolerance for anything edge-case
Fees¶
| Item | Cost |
|---|---|
| Monthly fee (Starter) | $0 |
| Monthly fee (Grow) | $30 |
| Monthly fee (Scale) | $90 |
| Domestic wire (Starter) | $5 outgoing |
| International wire (Starter) | $10 outgoing |
| Same-day ACH | $5 (Starter/Grow), $1 after 10 free (Scale) |
| Card payments received | 2.9% + $0.30 |
| Cross-currency transfers | 1% fee |
| Foreign transaction fees | None on debit card |
Accounting Integrations¶
- Native: QuickBooks Online, Xero
- Zoho Books: No direct integration. Possible via Plaid (both Relay and Zoho Books support Plaid). Manual CSV/OFX import as fallback.
- Integrates with Gusto, Hubdoc, Dext
Verdict: NOT RECOMMENDED¶
Relay's explicit crypto prohibition and stricter address verification make it a poor fit for Research Relay LLC. The crypto ban alone is disqualifying given our BTC payment acceptance.
3. Novo¶
Website: novo.co Banking Partner: Middlesex Federal Savings (Member FDIC) FDIC Coverage: $250,000 (standard FDIC, no sweep)
Signup Process¶
- 100% online, under 10 minutes
- Approval within 1-3 business days (some same-day)
- Required: SSN, government-issued ID, EIN, Articles of Organization
- Must have a mobile phone on a major U.S. carrier
Address Requirements¶
- Requires a physical U.S. address -- proof of address (utility bill, lease) may be required
- Registered agent address: Rejected. Novo explicitly requires proof of a physical U.S. address. Using a registered agent address leads to automatic rejection.
Crypto Policy¶
- Cryptocurrency businesses are explicitly prohibited. Novo does not accept businesses specializing in cryptocurrency alongside cannabis, gambling, crowdfunding, and money services.
Research Chemicals / High-Risk Tolerance¶
- No explicit mention of research chemicals on the restricted list
- Very limited FDIC coverage ($250K) suggests Novo targets small, low-risk businesses
- Conservative partner bank (Middlesex Federal Savings)
Fees¶
| Item | Cost |
|---|---|
| Monthly fee | $0 |
| Account minimums | None |
| Transaction fees | None |
| ACH (in/out) | Free |
| Incoming wires | Free |
| Outgoing domestic wires | Not available to all customers |
| ATM fees | Refunded up to $7/month |
| NSF fee | $27 |
Accounting Integrations¶
- Native: QuickBooks Online, Xero, Wave, FreshBooks
- Zoho Books: Not listed as a native integration. Manual CSV import likely required.
Verdict: NOT RECOMMENDED¶
Novo's explicit crypto prohibition, limited FDIC coverage ($250K only), inconsistent wire transfer availability, and no-cash-deposit policy make it unsuitable. The crypto ban is disqualifying.
4. Bluevine¶
Website: bluevine.com Banking Partner: Coastal Community Bank (Member FDIC) FDIC Coverage: Up to $3M via Insured Cash Sweep
Signup Process¶
- 100% online
- Approval within 3 business days
- Required: EIN, Articles of Organization/Incorporation, two forms of ID per signatory (at least one photo ID), annual gross revenue information
Address Requirements¶
- Requires a physical business address and primary phone number
- Home address is acceptable if you work from home
- Registered agent address: Explicitly not accepted. Bluevine's documentation states registered agent addresses "will prevent you from opening an account."
Crypto Policy¶
- "Financial institutions and lenders (including insurance, penny auction companies, and cryptocurrency)" are listed as restricted industries
- Specifically, "bulk exchanges of virtual currency (e.g., cryptocurrency)" are restricted
- For our use case: Bluevine restricts crypto exchanges/trading businesses. A business that merely accepts BTC payments through a third-party processor (receiving only USD into the bank account) is in a gray area. The account would only see incoming USD deposits from a payment processor -- Bluevine may never know about the BTC origin. This is less risky than with Relay/Novo but still carries some risk if Bluevine investigates the payment source.
Research Chemicals / High-Risk Tolerance¶
- Research chemicals and supplements are not explicitly on Bluevine's restricted list
- Bluevine markets to small businesses broadly, not just tech startups
- The restricted list focuses on financial services, crypto, cannabis, and weapons
Fees¶
| Item | Cost |
|---|---|
| Monthly fee (Standard) | $0 |
| Monthly fee (Plus) | $30 (waivable with $20K balance + $2K card spend) |
| Monthly fee (Premier) | $95 (waivable with $100K balance + $5K card spend) |
| APY (Standard) | 1.30% on balances up to $250K |
| APY (Plus) | 1.75% on balances up to $250K |
| APY (Premier) | 3.00% on balances up to $3M |
| Incoming domestic wires | Free |
| Incoming international wires | $25 |
| ACH direct debit (customer payments) | 1% fee |
| MoneyPass ATMs | Free |
Accounting Integrations¶
- Native: QuickBooks Online, QuickBooks Desktop, Xero, Zoho Books, FreshBooks, Wave
- Zoho Books: Yes, native one-click integration. This is a significant advantage.
- Also integrates with Stripe, Square, PayPal, Shopify Payments, Amazon Pay
Pros¶
- Native Zoho Books integration (unique among fintech banks researched)
- Competitive APY on balances
- Up to $3M FDIC insurance
- Invoicing and payment links (powered by Stripe)
- Home address acceptable as business address
- Broad e-commerce integrations (Stripe, Square, PayPal, Shopify, Amazon)
Cons¶
- Registered agent address explicitly rejected
- Crypto is a restricted (not prohibited) category -- gray area for BTC payments
- 3 business day approval (slower than Mercury)
- 1% fee on ACH direct debit for customer payments
- International wire fees ($25 incoming)
5. Arc¶
Website: joinarc.com Banking Partners: Multiple (FDIC insured up to $250K for operating; up to $5M for Treasury via sweep) Focus: Venture-backed technology startups
Signup Process¶
- 100% online
- Partnership with Firstbase for company formation + banking
- Focus on VC-backed tech startups
Address Requirements¶
- Not well documented publicly
- Arc primarily targets funded startups that typically have office space
- Unclear whether registered agent addresses are accepted
Crypto Policy¶
- No public documentation found on restricted industries
- Arc's focus on tech startups suggests some crypto tolerance, but unconfirmed
Research Chemicals / High-Risk Tolerance¶
- Arc positions itself exclusively for "technology companies" and "venture-backed startups"
- An RUO research chemical e-commerce business likely does not fit Arc's target customer profile
- Approval seems algorithmically based on "operating metrics" -- a pre-revenue or early-stage e-commerce LLC may not qualify
Fees¶
| Item | Cost |
|---|---|
| Monthly fee (Operating/Reserve) | $0 |
| Treasury management | Starting at 0.10% monthly volume-based |
| Treasury yield | Up to 3.73% APY |
| Business account rewards | Up to 3.0% on funds |
Accounting Integrations¶
- Partnership with Digits (AI accounting platform)
- Archie AI CFO agent connects to your accounting system
- No confirmed native QuickBooks/Xero/Zoho Books integrations found
Verdict: NOT RECOMMENDED¶
Arc is designed for VC-backed tech companies, not bootstrapped e-commerce LLCs. The application may be rejected simply because the business profile does not match their target customer. Limited public documentation on policies makes risk assessment difficult.
6. Brex¶
Website: brex.com Banking Partner: Column N.A. (Member FDIC) for checking FDIC Coverage: Up to $6M via Vault (sweep across partner banks)
Signup Process¶
- 100% online
- Review within 1-3 business days
- Required: EIN, Articles of Organization, SSN for identity verification (not for credit check), physical U.S. address with proof
- Single-member LLCs are eligible
Address Requirements¶
- Requires a valid US physical address
- Registered agent address: Likely not accepted. Brex requires a "physical U.S. address with proof."
Crypto Policy¶
- Cryptocurrency dealing is listed as a restricted (not prohibited) activity
- Restricted means additional review during onboarding and periodic check-ins -- does not automatically disqualify
- Major development: Brex announced stablecoin (USDC) payment acceptance in 2025-2026, with free instant USDC-to-USD conversion
- Digital asset firms (Figure, Solana, Alchemy) are Brex customers
- For our use case: Brex's crypto stance is the most favorable among all banks researched. They actively serve crypto companies and are integrating stablecoin payments.
Research Chemicals / High-Risk Tolerance¶
- Brex's restricted list includes "gray market goods" -- research chemicals could potentially fall under this category
- Research chemicals are not explicitly named as restricted or prohibited
- Brex targets "growth-oriented" companies -- e-commerce fits
- However: Brex requires $50,000 minimum cash reserves for the corporate card, which may be a barrier for an early-stage business
Fees¶
| Item | Cost |
|---|---|
| Monthly fee | $0 (Essentials plan) |
| Account minimums | None for checking; $50K for corporate card |
| Premium plan | Available (pricing varies) |
| Annual fee | None |
Accounting Integrations¶
- Native integrations with QuickBooks Online, Xero, NetSuite
- Zoho Books: Not confirmed as a native integration
- Strong expense management and receipt capture built in
Capital One Acquisition Note¶
Capital One announced acquisition of Brex in January 2026 for $5.15B. Expected to close mid-2026. This creates uncertainty about Brex's future product roadmap, pricing, and policies.
Verdict: CONDITIONAL RECOMMENDATION (if you have $50K+ in reserves)¶
Brex has the best crypto stance but requires significant capital and may classify research chemicals as "gray market." The pending Capital One acquisition adds uncertainty. Best suited if the business is well-capitalized.

Recommendations¶
Primary: Mercury¶
Mercury is the strongest option for Research Relay LLC because:
- Crypto tolerance -- Mercury banks thousands of crypto/web3 companies and does not prohibit purchasing crypto on exchanges. Our BTC payment flow (third-party processor converts BTC to USD, deposits USD into Mercury) should work without issues.
- No explicit restriction on research chemicals -- Mercury's prohibited industries list is narrow (adult, cannabis, gambling, MSBs). E-commerce and supplements are explicitly supported.
- Free wire transfers -- Both domestic and international USD wires are free, which is excellent for a business with potential wholesale suppliers.
- $5M FDIC coverage -- Strong protection via sweep network.
- E-commerce integrations -- Shopify, Stripe, Amazon integrations built in.
- No minimums, no monthly fees -- Perfect for a startup with variable early revenue.
Address workaround: Use your personal home address as the business/legal address on the Mercury application. Your California LLC's registered agent (Northwest) is separate from your operating address.
Zoho Books workaround: Use Zapier to sync Mercury transactions to Zoho Books, or use CSV exports. Alternatively, consider starting with QuickBooks Online (native integration) and migrating to Zoho Books later.
Backup: Bluevine¶
If Mercury rejects the application or closes the account, Bluevine is the best backup because:
- Native Zoho Books integration -- This is a unique advantage that no other bank offers.
- Research chemicals not on restricted list -- Similar to Mercury, Bluevine's restrictions focus on financial services, cannabis, crypto, and weapons.
- $3M FDIC coverage -- Solid protection.
- Home address acceptable -- Explicitly allows working-from-home businesses.
- Broad e-commerce integrations -- Stripe, Square, PayPal, Shopify, Amazon.
Crypto caveat: Bluevine lists crypto as restricted. Since our Mercury account would only receive USD from a BTC payment processor, Bluevine would likely not see any crypto activity. However, if they ever investigate the source of deposits and trace them to a crypto payment processor, there is a risk of account restriction.
Tertiary: Brex (if well-capitalized)¶
If the business has $50K+ in cash reserves and wants the most crypto-friendly option, Brex is worth considering. Their stablecoin integration and active crypto-company customer base make them the least likely to have issues with BTC-adjacent payment flows. However, the $50K minimum for the corporate card and the Capital One acquisition uncertainty make this a conditional choice.
Not Recommended¶
- Relay -- Explicitly prohibits cryptocurrency businesses. Disqualifying.
- Novo -- Explicitly prohibits cryptocurrency businesses. Only $250K FDIC. Disqualifying.
- Arc -- Designed for VC-backed tech startups. Wrong customer profile.
