Shopify wasn't built for products sold by area or volume. We fixed that. Introducing Soul+Wolf's Area & Volume Ordering app — smarter quantity management for flooring, turf, concrete, stone, timber, and beyond.
The gap in Shopify's ordering logic
Shopify is built around a simple premise: a product has a quantity, and you buy units of it. For most products, that's fine. But for anyone selling flooring, turf, concrete, fabric, stone, timber, or any other product measured by area or volume, that model breaks down almost immediately.
How much lawn does a customer actually need? How many square metres of tile will cover their bathroom floor once you account for cuts and waste? These aren't questions most shoppers can answer off the top of their head — and if your store doesn't help them, they'll either abandon the cart, over-order, or call your team for help. None of those outcomes are good for business.
Soul+Wolf's Area & Volume Ordering app closes that gap — adding native m² and m³ ordering capability directly to your Shopify store, with an integrated calculator and smart rounding logic that takes the guesswork out of the equation entirely.
How it works
Step 1: Shopper selects or enters their required quantity
Customers can either use the integrated area/volume calculator — entering their dimensions (length × width, or length × width × depth for volume) — or input their required m² or m³ directly if they already know it.
Step 2: Wastage allowance is applied automatically
The calculator applies a configurable wastage percentage — set by the merchant per product — so customers always order enough to account for cuts, offcuts, and installation waste. No more coming up short mid-job.
Step 3: Quantity rounds to the nearest available increment
Merchants configure the increments their products are sold in — full boxes, rolls, bags, slabs, or any custom unit. The app automatically rounds the customer's requirement up (or optionally down) to the nearest available increment, so orders always make practical sense.
Step 4: Price updates in real time
As the quantity changes — whether through the calculator, manual input, or the increment stepper — the total price updates instantly on the product page. Customers always know exactly what they're committing to before they add to cart.
Step 5: Added to cart in the right unit
The confirmed quantity — displayed in the shopper's chosen unit (m² or m³) — is carried through to the cart, checkout, and order confirmation. Clean, clear, and consistent from product page to fulfilment.
Key features
📐 Integrated Area & Volume Calculator
Shoppers enter their dimensions and the app calculates the exact quantity needed — no mental arithmetic, no under-ordering.
🔁 Configurable Increments
Sell in boxes, rolls, bags, pallets, or any custom unit. The app snaps quantities to your pack sizes automatically.
⚠️ Wastage Allowance
Set a per-product wastage percentage so customers always order enough. Configurable per product type — a bathroom tile needs a different allowance to a roll of carpet.
💲 Dynamic Pricing
Total price updates in real time as quantity changes — giving customers full visibility of their spend before they commit.
📦 Minimum Order Quantities
Set minimum order thresholds per product to protect your margin and simplify fulfilment — the app enforces them cleanly in the UI.
⚙️ Merchant Admin Controls
Configure units, increments, minimums, and wastage percentages per product through a simple admin interface — no development required.
Built for any product sold by area or volume
While the app was designed with building, landscaping, and flooring merchants in mind, it applies to any product category where quantity is measured in area or volume rather than individual units.
If your customers regularly ask "how much do I need?" — or if wrong-quantity orders are a persistent source of returns and support tickets — this app is built for you.
