B2B Buyer Roles and Permissions

B2B buyer roles and permissions are the systems by which a B2B eCommerce platform manages who in a customer organization can do what. A customer account is not a single person—it’s a company with multiple employees, each with different responsibilities and purchasing authority. The platform must control which users can search, add to cart, submit orders, approve orders, view invoices, and manage other users.

This is a fundamental structural difference from B2C, where each customer account is one person with identical permissions.

Common B2B Roles

Buyer: Can search products, add to cart, and submit orders up to a spending limit. Cannot approve orders above threshold or manage other users.

Approver/Manager: Can approve orders submitted by buyers. Often has a higher spending authority.

Administrator: Can manage all account users, set purchasing policies, update shipping addresses, and view all orders and invoices. Usually a department head or procurement manager.

Finance/Accounting: Can view invoices, payments, and spending reports. Cannot order but has financial visibility.

Restricted User: Limited to a specific product category or supplier catalog.

How Permissions Work

Permissions are typically mapped to role. When a user logs in, the platform checks their role and restricts their view to allowed products, budgets, and actions. Approval workflows route orders to appropriate approvers based on amount.

For example:

• Order under $1,000: auto-approve
• $1,000-$5,000: requires one manager approval
• $5,000-$25,000: requires two approvals
• Over $25,000: requires CFO approval

Organizational Value

Without role-based permissions, everyone would have the same access level (chaos or over-restriction). Orders would bottleneck. Financial controls would be weak. Accounts would be insecure.

With well-designed roles and permissions:

• Buyers can order independently up to their authority
• Approvals happen automatically through workflows
• Spending is controlled and audited
• Account administrators can manage access without involving IT

Typical Account Structure

A B2B customer account includes:

• Administrator (Procurement Manager)
• Multiple Buyers with different spending limits
• Approver (Supply Chain Manager)
• Finance (Accounting, view-only)
• Restricted Users (if needed)

Each user can log in, see their allowed products and accounts, and perform their assigned tasks.

Design Considerations

Platform designers must think carefully about role definitions. Too many roles create confusion. Too few are restrictive. Most successful platforms ship with 4-6 pre-defined roles and allow customers to create custom roles if needed.

The platform should allow customers to define their own role hierarchy, support flexible spending limits and approval workflows, and make it easy for account administrators to add/remove users.
