JMS Dev Lab is an EU-based software studio and Shopify Partner based in Cork, Ireland. We build custom software and Shopify apps for businesses that are too niche for generic SaaS and too small for enterprise vendors.
We specialise in solving problems that off-the-shelf tools cannot handle: industry-specific CRMs, client portals, booking systems, job tracking tools, spreadsheet replacements, and workflow automation — all designed around how your business actually operates.
What We Build:
- Custom Shopify apps (public and private)
- Shopify admin extensions and integrations
- Internal tools and workflow automation
- Industry-specific software for retail, jewelry, sports, and professional services
Our Products:
We have seven production apps live, six on the Shopify App Store: JewelryStudioManager (CRM for jewelry studios), StaffHub (team training and management), Jewel Value (professional jewelry valuations), SmartCash (cashflow management with AI forecasting), RepairDesk (repair management for jewellers and watchmakers), and GrowthMap (guided marketing execution).
Our Stack: TypeScript, React, Node.js, PostgreSQL, Prisma, Shopify GraphQL API
How We Work: Fixed-price quotes. Working software in weeks. Ongoing support from the people who built it. GDPR compliant. No middlemen, no enterprise overhead.
