Real starting prices for Shopify store builds, themes, migrations, apps, B2B, audits and support retainers. Every project is quoted against a written scope — these are the numbers we start from.
Most Shopify agency quotes differ because they price different things. We price against a written scope, in one of three ways: a fixed price for a defined deliverable, time & material when the scope will move, or an on-demand retainer for ongoing work.
The prices below are the published starting points from each of our service pages. Your final number depends on catalog size, integrations, custom features and how ready your content is — share your brief and we respond with a scoped quote within 1 business day.

It usually comes down to three things: how well-defined your scope is, how you prefer to manage budget, and how much Shopify work is still ahead of you.
Best for well-defined, one-off builds
Choose when the scope is clear — a theme build, a Shopify migration, a B2B or Plus launch.
Best for live, growing stores
Choose when the store is live and needs steady, ongoing attention without hiring in-house.
Best for evolving, discovery-heavy work
Choose when the scope is still taking shape — complex integrations, roadmaps still being validated.
Most brands mix models over a store’s life — a fixed-price build to launch, time & material for a follow-on integration, then a retainer to keep improving. The same senior Mgroup team runs all three, so switching is seamless.
