For a small agency with multiple owners, which digital banks offer the most flexible user permissions and access controls for partners and staff?

For a small agency with multiple owners (partners) and various staff or external bookkeepers, modern digital business banking platforms have largely solved the rigid "all-or-nothing" login problem.

The digital banks and fintech platforms that offer the most flexible, granular user permissions and access controls stand out for their ability to isolate specific accounts, build custom roles, and establish multi-user approval workflows.support.mercury.com+2

Top Recommendations for Granular Permissions

• Relay Financial (Best for hyper-granular, account-level custom roles)
  • Why it shines: Relay offers deeply customizable Custom Roles on all plans at no extra cost. Unlike platforms that apply permissions globally, Relay lets you dictate access account-by-account.
  • Permissions Flexibility: You can give a partner or staff member full access to an operating account, limited visibility in a savings/tax account, and zero visibility into a payroll or specific client project account. You can toggle individual permissions (viewing balances, moving money, managing cards, handling bills) and apply them selectively.
  • Best for: Agencies that want compartmentalized access for different partners or want administrative staff/bookkeepers restricted strictly to specific sub-ledgers or accounts.relayfi.com
• Mercury (Best for customizable workflows and robust approval chains)
  • Why it shines: Mercury features robust preset roles (Admin, Bookkeeper, Employee) alongside deeply configurable Custom Roles.
  • Permissions Flexibility: Custom roles allow you to select specific account visibility, card issuance, and money-moving capabilities. Crucially, Mercury lets you set up payment approval policies (e.g., Partner A can initiate a wire or ACH transfer, but Partner B or a designated Admin must log in and approve it before the funds move).
  • Best for: Co-owned agencies that require dual-authorization (four-eyes principle) on outbound payments to prevent internal fraud or accidental large transfers.support.mercury.com+2
• Qonto (Best if operating in Europe/UK with strict corporate hierarchies)
  • Why it shines: Qonto specializes in European small-to-medium businesses and features highly structured role definitions tailored to teams.
  • Permissions Flexibility: It allows clear segregation between the primary Account Owner, standard team members, customized finance leads, and external accountants (who get a specialized read-only or book-prep portal). Customization scales up depending on your chosen subscription tier.
  • Best for: European-based or international agencies needing dedicated, standardized partner vs. employee logging profiles.support-it.qonto.com

Key Features to Look For in Your Evaluation

When comparing these platforms for an agency setup, ensure you map out your workflow against these criteria:

1. Account-Level Segregation: Can you hide specific revenue or reserve accounts from junior partners or general staff?
2. Approval Chains (Workflow Controls): Can you configure rules where one partner drafts a payment and another must authorize it?
3. Dedicated Accountant/Advisor Access: Can you invite your external CPA with secure, read-only or journal-entry-only capabilities that don't expose sensitive company settings?support.mercury.com+2

To help narrow down which of these fits best, tell me:

• Are you based in the US or internationally?
• Do you need multi-signature/dual-approval workflows for sending money, or just view/edit separation?

For a small agency with multiple owners, the most important features are usually separate logins, granular roles, payment approval workflows, account-level visibility controls, and audit trails—not just “multiple users.” Based on those needs, these are the digital banking platforms I’d shortlist:

How I’d think about the choice

1. If you have 2–5 equal partners

Mercury is usually the first one I’d evaluate. A common setup:

• Partners: admin or high-level approval roles
• Operations manager: payment preparation + limited account access
• Bookkeeper: accounting/reporting access only
• Employees: cards and reimbursements only

Mercury’s role system is designed around controlling access to money movement, accounts, cards, and sensitive settings.Mercury

2. If you want “virtual departments” or project separation

Relay is worth a close look.

Example structure:

• Operating account
• Payroll account
• Tax account
• Contractor account
• Client/project accounts

This can make it easier for partners to see only the funds they’re responsible for.

3. If your agency has lots of SaaS, ads, travel, or employee spending

Brex or Ramp may outperform traditional banking tools.

For example:

• Designer gets a card limited to software purchases
• Account manager gets a client-expense budget
• Partner approves large payments
• Finance person reconciles transactions

Brex supports multiple role types and (on eligible plans) custom roles with granular permissions. Brex Ramp similarly separates roles such as Owner/Admin, Accounting, Employee, and AP-related access.Ramp Help Center

Minimum permission checklist I’d require for a multi-owner agency

Before choosing, confirm you can:

• ✅ Give every person their own login
• ✅ Avoid sharing owner credentials
• ✅ Separate “can view” from “can move money”
• ✅ Require approval for outgoing payments
• ✅ Give bookkeepers access without giving them payment authority
• ✅ Restrict employees to their own cards/expenses
• ✅ Remove a person’s access immediately when roles change
• ✅ Export an audit trail

For a typical small creative, marketing, consulting, or software agency, I’d generally compare Mercury vs. Relay first, then add Brex/Ramp if employee spending controls are a major concern.Ramp

If you tell me your setup (for example: 3 partners + 8 employees + outside bookkeeper), I can suggest a specific permission model.

For a small agency with multiple owners, traditional banks often force an all-or-nothing approach to authorization, or charge heavy fees for complex cash management add-ons. Modern digital-first platforms (fintechs partnered with FDIC-insured institutions) handle multi-owner and multi-user access far more fluidly.

The digital business banking platforms offering the most flexible user permissions, access controls, and multi-layered approval workflows stand out in specific ways for partners and staff:

1. Relay Financial (Best Overall for Granular Role Separation)

Relay (partnered with Thread Bank) provides one of the most comprehensive permission frameworks available for small businesses, utilizing 6 distinct preset roles rather than a crude "all-access" binary.relayfi.com+1

• Partner/Co-Owner Roles: Admin role provides full control over accounts, settings, and team management. However, you can also designate certain co-owners or operations leads as Managers , giving them the ability to issue cards and manage team members without granting them the power to move money.relayfi.com
• Staff/Bookkeeper Roles: Bill Payer allows staff or external bookkeepers to initiate ACH, wires, and checks, but explicitly bars them from issuing cards or modifying account settings.relayfi.com
• Read-Only / Silent Partners: A Read Only role gives passive partners, accountants, or auditors visibility into balances and statements without any transaction capabilities.relayfi.com
• Why it fits agencies: You can cleanly isolate operational spend (issuing employee cards) from cash disbursement authority (paying agency vendors).

2. Mercury (Best for Customizable Workflows and Dollar Thresholds)

Mercury (partnered with Choice Financial Group and Evolve Bank & Trust) is built heavily for collaborative teams and tech-forward small businesses. It features Admin, Bookkeeper, Cardholder, and highly customizable Custom User roles.support.mercury.com+2

• Custom Permissions: You can toggle specific money-movement permissions on or off per user, limit access to specific sub-accounts, and dictate whether they can manage vendors or invoices.support.mercury.com
• Multi-Layered Approval Policies: Mercury shines by letting you create custom approval rules for money out. For instance, you can configure a policy requiring that any transfer or wire over a certain dollar amount needs secondary sign-off from a designated co-owner or managing partner.relayfi.com+1
• Why it fits agencies: If partners want individual autonomy on day-to-day spending but need strict dual-authorization checkpoints for large client disbursements or agency bonuses, Mercury’s conditional rules handle this smoothly.

3. Airwallex (Best if the Agency Operates Globally / Multi-Currency)

If your agency handles international clients, contractors, or multi-currency billings, Airwallex provides robust enterprise-grade custom user management at no extra cost.

• Role Flexibility: Beyond standard Owner and Admin controls, they offer pre-built roles like Analyst (can transfer/convert currency), Cardholder, Developer , and View Only , alongside fully custom roles where you build the precise permission matrix needed.
• Why it fits agencies: It allows you to safely grant overseas media buyers or project managers access to local foreign currency wallets or dedicated virtual cards with strict caps, minimizing risk.

Key Comparison for Multi-Owner Decision Making

• Avoid platforms like Novo: While popular for solo freelancers, they generally lack granular role controls and treat any added user as having full account access.
• Best Practice for Setup: Designate Admins strictly to active co-owners who need legal and structural control over the bank relationship. Give secondary operational partners the Manager or Custom roles with conditional payment thresholds to protect the partnership from accidental or unilateral large-scale transfers.fire.com+2

If you'd like to narrow this down further, tell me:

• Do you need multi-currency / international wire capabilities?
• Do you require physical/virtual employee cards with custom spending limits, or just checking/ACH access?
• How many total partners and staff need access?

For a small U.S. agency with multiple owners, I’d focus on role granularity, account-level permissions, payment approvals, and whether owners can be separated from day-to-day staff. Based on current published controls, these are the strongest options:

Mercury

Mercury is particularly well suited if the agency has several owners who need different degrees of control.

Its Custom roles let you choose specific capabilities—such as sending money, managing recipients, issuing cards, handling accounting, or managing users—and separately determine which accounts the person can access. Mercury also supports approval rules with thresholds, multiple approvers, daily sending limits, and dual-admin approval for sensitive actions.Mercury+1

A practical setup could be:

• Owner A: full administration
• Owner B: banking + payment authority, but not user administration
• Bookkeeper: account/transaction visibility without money movement
• Account manager: card/spend access only
• Staff: cards and their own transactions

Brex

Brex offers similarly granular controls. Its standard roles cover admins, bookkeepers, AP clerks, employees, etc., while custom roles allow more precise permissions on eligible plans.Brex+1

Brex also supports payment approvals when there are multiple account admins, including customizable approval chains.Brex

This is attractive if your agency wants banking combined with cards, expenses, bill pay, and employee spending controls.

Ramp

Ramp has an unusually extensive permissions model. It separates base roles from add-on roles and allows many permissions to be toggled individually. For example, Accounting or Finance Admin users can be given banking access without making them full owners.Ramp Help Center+1

Ramp also supports transfer approval rules and a separation-of-duties control intended to prevent someone from approving their own transfer.Ramp Help Center

The tradeoff is that Ramp is more of a financial-operations/spend-management platform than a simple business checking account.

Chase Business

Chase is worth considering if you want a traditional bank rather than a fintech-first platform. Chase Business Online lets administrators assign no access, view-only, transact, or view-and-transact access on an account-by-account basis, with transaction types and monetary limits configurable for users. Chase says businesses can create up to 99 users with different access levels.Chase

Its permissions aren't as granular or modern as Mercury's custom-role system, but it's a robust option when multiple partners need clearly defined banking authority.

My practical shortlist

For an agency specifically concerned with multiple owners + staff permissions, I'd investigate Mercury and Brex first, with Ramp particularly interesting if spend management and approvals are a major part of the workflow. Chase is the more traditional-bank alternative.

One important distinction: don't just ask whether a bank supports "multiple users." Ask whether it supports separate permissions for (1) viewing balances, (2) initiating payments, (3) approving payments, (4) adding/removing users, and (5) accessing individual accounts. That's where the products differ most.Mercury+2

If you tell me roughly how many owners, staff, and outside bookkeepers you have, I can lay out a sample permission structure for each of these four platforms.

For a small agency with multiple owners, I’d prioritize banks that let you separate ownership/admin rights, payment authority, bookkeeping, and employee spending rather than simply giving everyone “admin” access.

My shortlist

1. Mercury — my first choice

Mercury has unusually granular controls for a small business. You can give owners/admins broad access while creating custom roles for other partners, bookkeepers, and staff. Custom users can be limited to particular accounts and can be granted or denied capabilities such as moving money, managing cards, or managing users.Mercury Support+1

Its approval system is particularly useful for multiple owners: you can set dollar thresholds, designate multiple approvers, impose daily sending limits, and use dual approval/separation-of-duties controls.Mercury Support+1

A good agency setup might be:

• Owner A + Owner B: Admin/custom financial authority
• Bookkeeper: accounting/view access, no money movement
• Operations manager: selected accounts + card management
• Employees: cards only
• Large payments: require approval from two owners

2. Relay — simplest role-based approach

Relay offers six permission levels—Admin, Manager, Bill Payer, Cardholder, Deposit Only, and Read Only—and each person gets their own login. That's a very clean model for an agency where, for example, owners need broad access while a bookkeeper or employee should see only what they need.Relay

I'd favor Relay over Mercury if your main concern is easy-to-understand delegation rather than maximum customization.

3. Ramp — strongest controls if spending is complex

Ramp is arguably more sophisticated than you need for basic banking, but it's excellent if the agency has lots of cards, employee spending, bills, reimbursements, or approval workflows.

It has separate roles for Owners/Admins, Accounting, Employees, IT, AP, Managers, Finance Admins, etc. On Ramp Plus, you can create custom roles and toggle individual permissions, including banking access.Ramp Help Center+1

Its banking approvals can also distinguish transfers/withdrawals and use specific individuals or groups as approvers, with separation-of-duties controls.Ramp Help Center

The catch: Admin/Owner is essentially all-powerful, so you should be deliberate about who gets that role.Ramp Help Center

4. Brex — powerful, but probably overkill

Brex supports standard roles plus custom roles, with custom roles available on its higher-tier plans. Brex It's attractive if your agency is becoming a larger operation with substantial card/spend-management needs, but for a small owner-operated agency I'd generally choose Mercury or Relay first.

Bottom line

I'd rank them:

1. Mercury — best combination of banking + granular permissions + multi-owner approvals.
2. Relay — easiest permission model and excellent for straightforward delegation.
3. Ramp — best if employee spend, cards, AP and approval workflows are central.
4. Brex — strong, but generally more platform than a small agency needs.

One important distinction: don't confuse “multiple owners” with “multiple admins.” For an agency, I'd generally keep the number of true super-admins very small and give the other owners/partners custom financial permissions plus dual approval for significant payments. That gives partners operational access without making every partner capable of unilaterally changing users or moving all the company's money.

I'd favor Relay over Mercury if your main concern is easy-to-understand delegation rather than maximum customization.

Bottom line

I'd rank them:

For a small agency with multiple owners, partners, and staff, having granular access control is crucial to prevent unauthorized fund transfers, streamline bookkeeping, and separate operational oversight from spending power.

The top digital business banking platforms stand out for multi-owner and team permission flexibility:

1. Relay Financial — Best for Preset, Granular Role Hierarchy
   • Overview: Relay offers one of the most structured and comprehensive permission systems for small teams, utilizing 6 distinct preset team member roles.
   • Key Roles:
     • Admin / Co-Owner: Full control over accounts, moving money, and team management.
     • Manager: Can issue/freeze cards and invite team members, but has zero authority to move money. Perfect for operations leads.
     • Bill Payer: Can initiate ACH, wires, and checks for accounts assigned to them, but cannot issue cards or change settings. Ideal for staff accountants or bookkeepers.
     • Cardholder / Deposit Only / Read-Only: Great for restricting staff to specific spending limits or giving silent partners/auditors view-only access.
   • Why it fits: It prevents operational managers from touching cash and stops bill payers from issuing corporate cards, isolating duties cleanly among partners and employees.relayfi.com+2
2. Mercury — Best for Custom Roles and Multi-Admin Approval Workflows
   • Overview: Mercury provides robust admin controls alongside fully customizable user roles, making it ideal if your agency's co-owners require multi-signature or dual-authorization rules for large expenses.
   • Key Roles:
     • Admins: Full access, but you can configure security controls requiring secondary admin sign-off/approval on specific payment requests or account changes.
     • Bookkeeper / Accountant: Templated custom roles restricted to viewing and coding transactions without transfer privileges.
     • Custom Users: Highly flexible; you can toggle specific account visibility, card issuance, user management, and money-movement rights granularly per person.
   • Why it fits: If your agency owners want a corporate governance structure where large outgoing wires require approval from a second partner, Mercury’s policy engine handles this seamlessly.support.mercury.com+3
3. Found or Novo — Best for Simpler, Streamlined Freelance/Agency Micro-Teams
   • Overview: While platforms like Found and Novo support team and sub-user access, their permission layouts are less complex than Relay or Mercury.
   • Why it fits: If your agency is very lean (e.g., two co-founders and one part-time bookkeeper) and you don't need heavy multi-tiered corporate governance, their streamlined team access models get everyone logged in without an overly steep configuration process.found.com+1

Recommendation Summary

• Choose Relay if you want out-of-the-box role separation (separating card management from bill pay and fund transfers).
• Choose Mercury if you need bespoke custom permission combinations or require dual-admin sign-offs on transactions.support.mercury.com+2

If you'd like to narrow this down, let me know:

• How many co-owners vs. regular staff need access?
• Do you require multi-signature / dual-approval rules for sending payments?

For a small agency with multiple owners, I’d shortlist Mercury, Relay, and Ramp, with Brex as a strong alternative if employee spending/card controls are the bigger concern.

My ranking

1. Mercury — best overall for a multi-owner agency

Mercury is the one I'd investigate first if you want separate people to have different powers rather than simply making everyone an account user.

It's particularly well suited when you have, for example:

• 2–3 owners who need substantial access
• A bookkeeper who needs financial visibility but shouldn't control everything
• An operations person who can initiate payments
• Staff who need cards without broad banking access
• Approval requirements before money actually leaves the company

Recent comparisons continue to put Mercury among the strongest choices for business banking plus team controls.Ramp+1

Best for: a conventional agency that wants its bank account to remain the central financial system.

2. Relay — arguably the best for dividing responsibilities

Relay is especially attractive if your agency likes to keep money separated into different accounts—for example:

Operating → Payroll → Taxes → Client/project funds → Owner distributions

Its account structure and team-access model make it a particularly good fit for agencies that want partners or staff to see/use only the accounts relevant to their job. Current comparisons specifically identify Relay as strong for complex payment workflows and multiple checking accounts with granular permissions.LaunchAdvisor+1

Best for: an agency where who can access which pot of money is as important as who can make payments.

3. Ramp — best if you want extremely granular controls

Ramp is somewhat different: it's more of a financial operations/spend-management platform than a traditional digital bank.

But its permissions are exceptionally flexible. It supports roles such as Admin/Owner, Accounting, Finance Admin, Manager, Employee, AP, IT Admin, View-Only Admin, and Guest. On its Plus plan, admins can customize roles and create entirely custom roles.Ramp Help Center+1

For example, an accounting person can potentially have accounting access without being able to issue spending, while a manager can control spending for their own team. Ramp can also restrict eligible roles to particular business entities.Ramp Help Center+1

Best for: agencies with lots of employee spending, cards, reimbursements, AP, and approval workflows.

4. Brex — excellent for spending controls

Brex is compelling if the problem you're trying to solve is less "who can access our bank accounts?" and more "who can spend company money, how much, and on what?"

It combines banking with corporate cards and expense controls, although its emphasis is more on spend management than traditional business banking.Ramp+1

What I'd choose for your agency

If I were setting up a 2–4 owner, 5–15 person agency, I'd probably evaluate them in this order:

Mercury → Relay → Ramp

The deciding factor would be your desired permission model:

• Equal partners + limited-access bookkeeper: Mercury
• Partners + highly segmented bank accounts: Relay
• Partners + lots of employee cards/expenses/approvals: Ramp
• Heavy corporate-card spending: Brex

One thing I'd insist on regardless of provider: don't give every owner/staff member "Admin" simply because they need access. Ideally you want separate logins, role-based permissions, payment initiation versus approval, account-level access, spending limits, and an audit trail.

If you tell me how many owners, employees, and bookkeepers you have and who should be able to initiate/approve payments, I can map out the exact permission structure I'd use for the agency.
