MFBV Group Price for Magento 2

Per-customer-group base price override — set a dedicated base price per customer group and website. That price becomes the effective regular price for matching customers, so catalog price rules, the price index, layered navigation, and APIs stay consistent end to end.

Why this extension

Magento’s native Group Price behaves like a discount from the catalog price. MFBV Group Price is built for B2B and multi-segment scenarios where a group’s negotiated price is the new baseline: catalog rules apply on top of that baseline, and the storefront price stack (list vs. special, rules, indexers) treats it as RegularPrice, not a parallel tier.

Features at a glance

• Admin Advanced Pricing — Dynamic rows under Advanced Pricing to assign customer group + price per website scope.
• Global on/off — Stores → Configuration → Catalog → Group Price → Enable Group Price hides admin UI, ignores saves, and restores default catalog behavior when disabled.
• REST API — Full CRUD-style access: list, upsert, and delete group prices by SKU (admin token + ACL).
• Product import — Native catalog product CSV extended with _group_price_* columns; validation and sample file include the new fields.
• Indexer integration — Hooks into catalog product price and catalog rule indexers plus dimensional price paths (simple and grouped), so listings, Elasticsearch/OpenSearch buckets, and cart/checkout match the storefront plugin layer.
• Performance-minded — Bulk repository reads for indexer runs; per-request in-memory resolution; optional Update by Schedule on price/rule indexers recommended for large catalogs.

Notable technical details

These points matter for merchants, agencies, and reviewers:

1. RegularPrice replacement — A RegularPrice plugin resolves the group-aware amount before catalog rules; unconfigured groups fall back to the normal catalog price.
2. Catalog rules use the group base — CatalogRuleIndexerPlugin rebases rule output so percentage/fixed rules apply from the group price, not the global list price.
3. Price index correctness — ProductPriceIndexerPlugin and DimensionalIndexGroupPricePlugin align final_price / min_price / max_price per customer group so category pages and search filters are not wrong for logged-in segments.
4. Declarative schema — Data lives in mfbv_group_price with FKs to product, customer group, and website; unique per (entity_id, customer_group_id, website_id).
5. Import semantics — Group prices are processed after product import bunches (aligned with tier price–style workflows); behavior respects module enable flag and import mode.
6. ACL — MFBV_GroupPrice::manage (REST + admin operations) and MFBV_GroupPrice::config (system configuration).
7. Compatibility awareness — Third-party RegularPrice plugins (e.g. B2B shared catalog, Amasty/Mirasvit pricing) may need sortOrder review in etc/di.xml; MSI does not conflict.

Requirements

• Magento 2.4.x (tested on 2.4.5–2.4.7-class stacks)
• PHP 8.1+
• MySQL 8.0+ or MariaDB 10.6+
• Modules: Magento_Catalog, Magento_CatalogImportExport, Magento_ImportExport, Magento_CatalogRule, Magento_Customer (see composer.json for version constraints)

Installation

Composer (recommended)

Manual

1. Copy the GroupPrice package under app/code/MFBV/GroupPrice/.
2. Run:

setup:upgrade creates the mfbv_group_price table from etc/db_schema.xml.

Configuration

Stores → Configuration → Catalog → Group Price → General → Enable Group Price

When disabled: storefront uses default catalog prices only, admin group price fields are hidden, and saves/imports do not apply group rows.

Admin usage

1. Edit a product in Admin.
2. Open Advanced Pricing (link above the Price field).
3. In Group Prices, use Add to set Customer Group and Price (per website as shown in the form).
4. Leave a group unset to keep the global catalog price for that segment.
5. Save the product.

Grant roles Catalog → Manage Customer Group Prices and Catalog → Group Price Configuration as needed under System → User Roles.

Product import (CSV)

The catalog product import adds these columns (also present in the downloadable sample when the module is enabled):

Validation runs with the standard product import validator pipeline.

REST API

All routes require an admin integration or session with permission MFBV_GroupPrice::manage.

See Api/GroupPriceManagementInterface.php and etc/webapi.xml for the service contract.

Price stack (simplified)

Indexers mirror this so indexed prices match runtime resolution for each customer group.

Indexer and performance

For high-volume catalogs, set both indexers to Update by Schedule to avoid long synchronous reindex on admin saves:

Typical overhead on full reindex is moderate (single-digit to low teens percent vs. baseline); background mode avoids blocking the admin UI.

Storefront caching: Magento already varies by customer group where required; no extra cache keys are introduced by this module for that reason alone.

Uninstall

Declarative schema removes mfbv_group_price when the module is disabled and setup:upgrade runs.
