Case study · Custom print and decoration
WeMust: a formula-priced DTF print-ordering platform on Shopify.
WeMust is a custom decoration company with production across Canada, supplying DTF heat transfers, patches, stickers and apparel to brands, print shops and decorators in Canada and the US. I built its self-serve ordering platform on Shopify alone: customers upload artwork, the store reads its width and height and prices the job live from a formula, and custom apps send production everything needed to fulfil it. Checkout rate rose 20% and manual work fell 90%.
My role
Lead Shopify developer and the only developer on the project. I built the whole store from scratch through launch, then supported it for another 5 to 6 months.

The problem
WeMust depended on manual quotes. It wanted customers to upload their own artwork and get an accurate price straight away, and the production team to receive everything needed to fulfil each order automatically.
Size-based pricing driven by formulas is something you would normally build on a custom stack like Next.js, and the brand wanted it running natively on Shopify.
What I did
- Built the whole store from scratch as the only developer, over about 5 to 6 months of development.
- Built a product page where customers upload their design and the system reads its height and width automatically. The price is calculated live from the dimensions, the chosen variant and a set of pricing conditions.
- Built the pricing logic on the Live Product Options app and extended it with custom code for the formulas, conditional variant pickers and real-time price changes the app couldn’t handle on its own.
- Built custom Shopify apps for operations that notify the team of new orders and send production the artwork, dimensions and specs for each job, so orders move straight into processing.
- Managed the site for another 5 to 6 months after launch, shipping new features and changes as the business grew.

Results
- Checkout rate
- +20%
- Manual work
- -90%
WeMust went from manual quotes to a self-serve ordering platform. Customers get instant, accurate prices on custom-sized prints, and the production team receives order data ready to produce. It is one of the most technically complex builds I’ve done on Shopify.
