[COMMERCE ENGINEERING — SHOPIFY & LIGHTSPEED]
The complicated end of e-commerce.
Most stores sell products. Some have rules — quantity breaks, configurable products, customer-specific pricing, systems that have to agree with each other. We build those, end to end, on Shopify and Lightspeed.
Direct for merchants. White-label for agencies. Building commerce systems for over a decade.
[WHAT WE BUILD]
01 / 04 ARCHETYPESComplete store builds
Architecture, templates, product structure, checkout, launch. Built from the ground up rather than bent out of a purchased theme — because the theme is never the part that fails.
Product configurators
Multi-step builds with live pricing, dependent options, quantity tiers and file upload. Designed to survive a catalogue rewrite instead of breaking on one.
Pricing and product rules
Quantity breaks, matrix variants, customer-group and contract pricing, VAT display per market. Generated and synced in bulk, not maintained by hand.
Systems that have to agree
ERP, PIM, carriers, lead delivery. Platform migrations that carry the pricing rules and custom data across, not just the products.

[HOW WE WORK]
04 / EXECUTION PROTOCOLSurgical changes. New behaviour goes in new files. Working code on a live store is a liability, not a canvas.
Complete files, not diffs. You get something you can deploy, not a patch to apply.
Caveats up front. If an approach has a limit, you hear about it before you pay for it — not after.
Overlapping hours. Our afternoon is your morning. Questions get answered inside your working day, not overnight.
