What is user access control?

User access control is the process of controlling who can access an eCommerce system, what information they can view, and which actions they are allowed to perform. It helps protect business data and ensures that users receive only the permissions necessary for their responsibilities.

In B2B eCommerce, access control can include:

• User authentication – Verifying users through passwords, multi-factor authentication, or other methods.
• Role-based permissions – Giving different access levels to administrators, sales staff, buyers, finance teams, and other users.
• Account-level access – Restricting customers to their own company account, catalogs, pricing, orders, or locations.
• Administrative permissions – Controlling who can modify products, prices, orders, customer records, or store settings.
• Approval controls – Requiring authorized users to approve certain orders, discounts, or purchasing actions.
• Access monitoring – Recording and reviewing login and permission-related activities.

For example, a B2B company might allow a purchasing employee to create orders and view company pricing, while only a finance manager can access billing information or approve high-value purchases.

Effective access control follows the principle of least privilege, meaning users receive only the access required to perform their role. Permissions should also be reviewed regularly and removed or updated when responsibilities change.
