The price is currently displayed only per 1 unit.
The price needs to automatically recalculate based on the quantity entered by the user.
As a result, two prices should be displayed simultaneously:
- price per 1 unit
- total price for the entered quantity

Example:

Product price: 10 UAH / unit
User enters: 50 units
Displayed:
- Price per 1 unit: 10 UAH
- Total price: 500 UAH

Requirements:

The recalculation must occur without reloading the page (via JS/Ajax).
It should work:
- on the product page
- correctly with promotions / discounts (if any)
The correct total amount must be passed to the cart.

The task is clear — it is necessary to add dynamic recalculation of the final price on the product page when changing the quantity, without reloading, with correct functioning of promotions/discounts. I have done similar work on OpenCart multiple times — this is a targeted refinement of the template + JS, without interfering with the core.

I will implement it as follows: on the product page next to the quantity field, I will add a block with two prices — "Price per 1 unit" (static) and "Total" (dynamic). When the quantity changes, the JS handler instantly recalculates the total on the client side, and for promotional prices and quantity discounts — I will make an Ajax request to the controller to get the current price considering all OpenCart pricing rules. This way, both regular prices and promotions, as well as volume discounts, are correctly processed. The correct amount is passed to the cart — there is no need to change anything here, OpenCart calculates the total itself when adding, it is only important to display it correctly on the front end.

Please write to me — I will clarify the version of OpenCart and the theme to provide the final price.

Good day!

I have experience in refining online stores on **OpenCart**, specifically working with the logic of displaying prices and custom JS/Ajax solutions.

I can implement:
• displaying **price per 1 unit**
• displaying **total price for the entered quantity**
• **dynamic recalculation without reloading the page**
• correct operation **with promotions and discounts**
• passing the **correct amount to the cart**

The recalculation will be performed immediately upon changing the quantity of the product, so the user sees the current total cost.

The solution will be made so that **it does not conflict with the current price calculation logic in OpenCart (special / discount)**.

**Deadline:** within 1 day.

Please let me know:

1. What **version of OpenCart** is being used?
2. Are there **quantity discounts** or **options that change the price**?
3. What **theme/template** is being used on the site?

After clarifying the details, I will be able to start the work.

In addition to counting the quantity, it is also necessary to consider working with promotions and discounts for groups of buyers, write in private to discuss.

Ready to implement this as a separate module that will correctly integrate into any theme without disrupting the template.

The module will:
- be neatly embedded in the product card
- work independently of the theme
- not break the standard update system
- easily scale if necessary

We have experience in developing custom modules and understand the architecture of OpenCart, so the implementation will be clean and conflict-free with other extensions.

Ready to start immediately.
