Cost Price OpenCart

The Cost Price module adds a separate cost price field for products in the OpenCart admin panel. This is a practical solution for stores that need to see not only the selling price, but also the internal purchase cost for catalog management, assortment analysis, and daily product handling.

Module purpose

Standard OpenCart functionality is usually focused on the selling price, while the cost price often remains outside the system or is stored in external spreadsheets. This module removes that limitation: it adds an extra field to the product form, displays it in the product list, and allows you to filter and sort products by cost price.

Important: the module works with data in the admin panel and is intended for convenient internal cost price management.

Main features

• adds a new Cost Price field to the product edit form;
• automatically creates the cost field in the product database table if it does not exist;
• saves cost price when creating a new product;
• updates cost price when editing an existing product;
• displays a cost price column in the product list;
• filters products by cost price value;
• sorts the product list by cost price;
• supports Russian and English admin language labels.

What the module changes

In the product form

• a separate field appears for entering the purchase cost;
• the value is loaded when editing a product;
• the data is stored in the database separately from the selling price.

In the product list

• a new Cost column is added;
• sorting by the p.cost field becomes available;
• a separate input for filtering by cost price appears in the filters panel;
• the cost price is shown alongside other key product parameters.

In the database and logic

• uses the cost field in decimal(15,4) format;
• checks whether this column exists in the product table;
• automatically adds the column if needed;
• performs read, write, update, filter, and sort operations on the data.

Benefits for the store

The key advantage of this module is simplicity and practicality. A manager does not need to keep cost prices in external spreadsheets, notes, or CRM comments. All important information is available directly in the OpenCart admin panel, exactly where product work is done.

• easier markup and margin calculations;
• simpler verification of актуal cost data;
• faster search for products with the required cost level;
• reduced risk of confusing selling price with internal cost;
• simplified workflow for catalog managers.

Usage examples

1. For a retail store: a manager enters the cost price and compares it with the selling price before updating the catalog.
2. For wholesale operations: you can quickly select products with a certain purchase cost and evaluate the assortment.
3. For analytics: the cost price field can be used as a base for future report improvements, profit calculation, and markup control.
4. For large catalogs: sorting and filtering help find needed products much faster without manually browsing dozens of pages.

Recommendations

After installation, it is recommended to fill in cost prices for key products and use a consistent value format. If several employees work with the catalog, it is worth defining in advance who is responsible for keeping this data up to date. The module is especially useful for projects where internal product economics matter as much as the storefront price.

Cost Price is a small but very useful OpenCart extension that makes catalog administration more informative and professional. It is suitable both for small online stores and for large catalogs where cost price is an important part of daily operations.
