Ensuring Accurate B2B Pricing: Resolving Customer Group Price List Mismatches in ESHOPMAN

Ensuring Accurate B2B Pricing: Resolving Customer Group Price List Mismatches in ESHOPMAN

At Move My Store, we understand that accurate pricing is the bedrock of any successful e-commerce operation, especially for businesses leveraging ESHOPMAN's advanced headless capabilities for B2B sales. ESHOPMAN, as a HubSpot application, empowers merchants to manage complex storefronts and deploy them seamlessly via HubSpot CMS. A core feature for many B2B clients is the ability to offer tiered pricing based on customer groups – think special rates for wholesalers, VIPs, or specific corporate accounts.

Recently, our community identified a critical issue where these carefully configured customer group price lists might not be applying correctly, leading to wholesale customers being silently charged default retail prices. This isn't just a minor glitch; it's a significant commercial defect that can erode trust and impact your bottom line. Let's dive into the technical details and the proposed resolution within the ESHOPMAN ecosystem.

The Core Business Logic Defect: A Context Key Mismatch

When an administrator sets up customer group price list rules using ESHOPMAN's Admin API, these rules are stored internally with a specific attribute, typically represented as 'customer_group_id', linked to an array of relevant group IDs.

However, when a customer interacts with your ESHOPMAN storefront (deployed via HubSpot CMS), the system processes their context to determine applicable pricing. During this process, the internal context middleware populates customer group information. For instance, it might structure the customer's groups like this:

pricingContext.customer = { groups: [] }
customerGroups.map((cg) =>
  pricingContext.customer?.groups?.push({ id: cg.id })
)

Further down the line, when ESHOPMAN's pricing repository calculates prices, it flattens this context into key-value pairs. This flattening can transform the customer group information into a key like "customer.groups.id". This is where the crucial mismatch occurs.

The system then attempts to query the database using the flattened key ("customer.groups.id") to match against the stored rule attribute ("customer_group_id"). Because these two keys do not match exactly, the SQL condition evaluates to false. Consequently, the customer group price list is never loaded, and the customer is inadvertently billed at the default retail price.

The ESHOPMAN Solution: Normalizing Context Attributes

To resolve this core issue and ensure that your customer group price lists apply as intended, the ESHOPMAN community has proposed an elegant solution involving rule aliasing within the pricing repository. This fix ensures that the system can correctly interpret and match customer group identifiers, regardless of slight variations in their representation between context generation and rule storage.

The proposed adjustment involves adding a normalization step within ESHOPMAN's Node.js/TypeScript-based pricing module. This step checks if the flattened context contains the "customer.groups.id" key. If it does, and the more direct "customer_group_id" key is absent, it explicitly adds an alias mapping, ensuring the database query finds the correct attribute.

Here's a simplified representation of the proposed logic:

// Map aliases: ensure customer_group_id matches customer.groups.id
const customerGroupIds = flattenedKeyValuePairs["customer.groups.id"]
if (customerGroupIds && !flattenedKeyValuePairs["customer_group_id"]) {
  flattenedContext.push(["customer_group_id", customerGroupIds])
}

This snippet ensures that even when the storefront context provides customer group IDs under "customer.groups.id", the pricing engine correctly associates them with the "customer_group_id" attribute stored in the price list rules. This small but critical change guarantees that your B2B customers receive their rightful tiered pricing, maintaining the integrity of your ESHOPMAN storefront.
