Customers and Customer Groups

​

Customer Types

Sigma CDD supports two customer types. The type you select determines which identity checks and risk criteria are available in your workflow.

​

Individual Customer Fields

When adding an individual customer, you provide:

• Full name (first name and last name)
• Date of birth
• Nationality / country of residence
• Phone number
• Email address
• Unique ID (your internal identifier for this customer, used for API lookups)
• Government ID details (BVN, NIN, passport number, or other document identifiers depending on the checks configured in your workflow)

​

Corporate Customer Fields

When adding a corporate customer, you provide:

• Business name
• Registration number
• Country of incorporation
• Business address
• Contact details
• Unique ID (your internal identifier for this entity)
• Beneficial owner details (directors and shareholders above the ownership threshold, typically 25%)

​

How to Add Customers

There are three ways to add customers to Sigma: Single entry (Dashboard)

1. Open Customers in the Sigma App
2. Click Add Customer
3. Select the customer type (individual or corporate)
4. Fill in the required fields and submit

Bulk upload (CSV) To add many customers at once, import a CSV file:

1. Open Customers and click Add Customer
2. Select Import customers from file
3. Download the CSV template for your customer type
4. Fill in the template, one row per customer
5. Upload the completed file

The import will validate each row. Rows with errors are flagged for correction before the import completes. API integration To add customers programmatically as part of your onboarding flow, use the CDD API. This is the recommended method for institutions processing high volumes.

​

Customer Records

Once added, each customer has a record in Sigma that stores:

• Profile data (the identity fields submitted at creation)
• CDD request history (all past and pending workflow runs)
• Risk profile (current risk tier and score from the latest completed run)
• Screening results (PEP, sanctions, and adverse media outcomes)
• Generated reports (compliance reports produced for this customer)

You can update a customer’s profile data at any time from their record in the dashboard or via the API.

​

Customer Groups

A customer group is a collection of customers of the same type. Groups let you organise your customer base and run CDD on multiple customers at once, useful for periodic reviews across a cohort. When to use groups:

• Running quarterly or annual reviews across a segment (e.g. all high-risk retail customers)
• Onboarding a batch of customers at the same time
• Tracking the progress of a bulk CDD run

How to create a customer group:

1. Open Customers and switch to the Customer Groups tab
2. Click Create Group
3. Enter a group name and select the customer type
4. Add customers to the group (you can add individually or import)
5. Save the group

Once a group is created, you can trigger a CDD run from the group view. Sigma processes each customer in the group using the selected workflow and reports progress in the dashboard.
