Senior Shopify Development for Agencies

Senior Shopify Development Without the Full-Time Hire

Q: What happens to unused hours each month?

Packages are designed for reliable availability. Unused hours do not roll over automatically, but priorities can be adjusted flexibly within the same month.

Q: How do communication and collaboration work?

Collaboration is primarily async via Slack/email and the team's ticket system (Jira/Linear/Trello), with meetings kept minimal and delivery kept central.

Q: What's the typical reaction time for requests?

Typically within 1 business day. Urgent issues can be flagged and handled faster if capacity allows.

Q: What are the scope boundaries for each package?

Retainers are ideal for ongoing development, improvements, bug fixes, and advanced Shopify work (including checkout customizations). Large greenfield builds or PM-heavy redesigns are better scoped as projects.

Q: What's your cancellation policy?

Month-to-month. Cancel anytime before the next billing cycle.

Q: Can work be delivered white-label for client projects?

Yes. Agency delivery can be supported under the agency brand, integrated into the existing delivery process.

Q: Do you handle theme or performance-related tasks?

Yes - the focus is senior-level engineering, but theme customizations, performance issues, and storefront fixes can also be handled when they affect delivery or conversion.

Senior Shopify capacity for agencies and technical teams where buying flows need to feel clearer, faster, and easier to operate - from custom storefronts and checkout logic to integrations and complex product experiences.
