## Frequently Asked Questions

### Why should a Montreal business hire Shopify Developer Pro over a local generalist agency?

Unlike generalist digital agencies in Montreal that build across WordPress, Magento, and Shopify using bloated templates, we are dedicated Shopify and Shopify Plus architects writing bespoke, high-performance Liquid code guaranteed to score 90+ on Google PageSpeed.

Generalist agencies often outsource or rely on visual page builders that cause severe mobile lag. Our team has deep expertise in Montreal's core trade sectors (Designer Fashion & Leather, Specialty Foods & Maple) and provides direct access to senior architects via +91-9119943505.

### What is the typical cost and timeline for custom shopify app development in Montreal?

Projects in Montreal typically range around CA$6,600 with a delivery timeline of 10 to 25 Business Days.

We operate on transparent milestone deliverables with zero hidden costs. All projects include responsive mobile QA, Core Web Vitals optimization, and 30 days of post-launch hypercare support.
