Task: refinement of Shopify checkout (calculator + configurator, multi-currency)

Budget: 500 USD Deadline: 4 days

Hello! Your task is a classic case for a Shopify developer working with Custom Product Builders. I fully understand the problem: Shopify by default tries to display all properties and system attributes, turning the cart into a "technical log" instead of a neat checkout. I specialize in custom solutions for Shopify and deep customization of Liquid/JS (30+ successful cases). I will implement a "clean" flow in the style of Photowall while preserving your pricing logic.
🛠 My plan to solve the task
1. Visual cleanup (Cart & Drawer)
* Filtering Line Item Properties: In the main-cart-items.liquid file (or similar in your theme), I will set up a loop to display properties in such a way as to hide technical keys (starting with _), leaving only those understandable to the customer: Size, Configuration.
* Hiding quantity: If your calculator passes area or volume in the quantity field, I will replace the display of this number with "1 pc." or completely hide the quantity line through CSS/Liquid, so the customer sees only the final custom product.
2. Working with Checkout (Limitations and Solutions)
* Shopify Plus: If you have a Plus plan, I will edit checkout.liquid for full customization.
* Basic/Advanced: If the plan is standard, access to checkout fields is limited. In this case, I will apply the technique of "packing" data into the product name or using hidden attributes that Shopify correctly displays on the receipt without unnecessary clutter.
3. Multi-currency (RON / MDL)
* Currency Logic: I will set up your JS calculator to pull the current Shopify.currency.active (or Cart object).
* Price Sync: I will implement real-time price recalculation. If the price in the calculator is fixed (Hardcoded), I will tie it to the store's conversion rate so that the amount in checkout in lei (MDL) is mathematically correct relative to the Romanian leu (RON).
📋 Stages and Deadlines
* Audit of the current JS code of the calculator: 1 working day.
* Cleanup of the cart and mini-cart (Liquid + CSS): 1–2 days.
* Setup of multi-currency and MDL logic: 1–2 days.
* Flow testing (from selection to payment): 1 day.
* Total timeframe: 4–6 working days.
💰 Estimated Cost
The cost of implementation "turnkey" including multi-currency: $450 – $750.
Why me:
I have experience working with wallpaper and custom curtain stores on Shopify, where the price depends on the entered dimensions ($/m²). I know how to "trick" the standard Shopify logic so that it does not display technical parameters in the order confirmation.
Bonus: I will check your site for Mobile UX for free, as on mobile. Expand

Good day
My name is Dmytro, from King Kong Lab. We have experience working with Shopify, including custom calculators, line item properties, and modifications to cart/checkout without disrupting existing logic.
We can carefully solve your task:
clean the cart and checkout from unnecessary technical elements
leave only the necessary data (configuration, sizes, final price)
create a clear and clean output like in Photowall
check data transmission and not break the current logic of the calculator
We will also set up correct operation with the second currency (MDL), so that the price from the calculator fully matches the checkout depending on the currency.
We work carefully with Liquid and Shopify limitations, without "hacks," to keep everything stable and scalable.
We are ready to review your project and quickly make adjustments.

Hello!

I am ready to refine your Shopify project and neatly bring the cart and checkout to a clean and understandable appearance without losing the current logic of the calculator.

Experience
Shopify (Liquid, cart, checkout limitations)
Custom calculators and configurator logic
Working with line item properties / custom pricing
Cleaning and customizing cart UI
Multi-currency (Shopify Markets / currency sync)

What I will do
Clean the cart / checkout
Hide unnecessary elements:
quantity lines (for example “221 items”)
technical line item properties
remove the display of “Custom dimensions” as a separate line
leave only:
sizes from the calculator
final price
selected configuration (preview/position)

I will provide a neat data output (in UX like Photowall)

Working with data
I will check the data transfer through line item properties
if necessary, I will optimize the structure (so that technical fields do not "shine")
ensure correct display without losing calculation logic

Multi-currency (RON → MDL)
I will set up the correct operation of the second currency
synchronize:
calculator price
price in cart / checkout
exclude discrepancies during conversion

Approach
Analysis of the current implementation (JS + Liquid)
Cleaning the cart display
Adjusting the structure of line item properties
Checking the checkout (considering Shopify limitations)
Setting up currencies and testing
Final polishing of the UI

Important
I understand the limitations of Shopify checkout (especially without Plus), therefore:
I do the maximum through cart + Liquid + JS
without breaking the current calculator
carefully, without affecting payment and orders

Estimate
Timeline: 2–5 days

Result

✔ Clean and understandable cart
✔ Correct display of configuration
✔ Price synchronization between currencies
✔ Stable operation without bugs

I am ready to review the current implementation and quickly make adjustments
