Common questions
Shopify is the standard plan and covers most merchants comfortably. Shopify Plus is the enterprise tier, and the differences that actually justify the cost are checkout customisation through Checkout Extensibility, Shopify Flow for automation, higher API rate limits, multi-store management through the Organization Admin, and a dedicated merchant success manager. It is generally aimed at merchants above roughly one million dollars in annual revenue, though revenue is a poor test on its own. The better test is whether you are currently blocked by something Plus unlocks. Teams running multiple regional storefronts, needing B2B company accounts alongside DTC, or hitting API limits during catalogue syncs have a clear case. Teams upgrading because growth felt like the right moment usually find they were not constrained by the platform, and the money would have gone further elsewhere.
Yes, and we generally try to talk you out of it first. Custom apps are built against the Admin API, Storefront API, and App Bridge, and we build both private apps for a single store and public apps for App Store listing. The reason for the hesitation is maintenance: a custom app is software you own indefinitely, including keeping pace with Shopify API version deprecations, which happen on a published schedule and will break an unmaintained app. An off-the-shelf app that covers eighty percent of your requirement is often the better trade, because someone else carries that burden. Custom becomes correct when the logic is genuinely specific to how your business operates, when you are paying for several overlapping apps that each solve part of the problem, or when an existing app cannot scale to your catalogue.
Hydrogen is Shopify’s official framework for building headless storefronts with React and Remix, deployed on Oxygen. It gives you full control over the frontend, the ability to outperform standard themes on Core Web Vitals, and one codebase serving multiple surfaces. Most merchants should not use it. Going headless means you own the storefront as an application: the theme editor stops being useful to your marketing team, every merchandising change becomes a deployment, and you take on frontend maintenance permanently. That is a real cost paid every month against a performance gain that a well-built standard theme often matches. It becomes the right call when you genuinely need a frontend that a theme cannot express, when you are serving several channels from one codebase, or when your team already runs React infrastructure and the marginal cost is low.
Yes. We migrate from WooCommerce, Magento, BigCommerce, Wix, and custom carts, covering products, variants, metafields, customers, and order history, with a redirect map built for every changed URL and a Search Console check after cutover. The parts that need attention early are variants and anything your old platform stored outside standard entities. Shopify has a hard limit on variant combinations per product, and catalogues built around configurable products with many option sets frequently exceed it, which means restructuring the catalogue rather than translating it. That is a merchandising decision as much as a technical one, so it needs your input rather than ours alone. We surface it during the pre-migration audit, because discovering it mid-build is what turns a predictable migration into an expensive one.
We build custom themes from scratch rather than heavily modifying a base theme, so there is no upstream conflict when Shopify updates its defaults. Where a store is already on a pre-built theme such as Dawn, we scope changes carefully and document exactly which files were modified and why, so a future update can be applied deliberately rather than avoided out of fear. The pattern that causes trouble is a base theme edited extensively over years by several people with no record of what changed. At that point updating means either losing customisations or manually reconciling every conflict, and most merchants choose to simply never update, which quietly accumulates security and compatibility debt. Documenting the diff is unglamorous and is the difference between a theme you can maintain and one you eventually rebuild.
Yes. Retainer support covers bug fixes, app and API version updates, incremental feature work, and performance monitoring. We also take one-off consultations where you have a specific problem on an existing store and do not want an ongoing arrangement, which is often the more sensible starting point. Worth flagging the Shopify-specific maintenance item that catches people out: Shopify deprecates API versions on a published quarterly schedule, and apps or integrations pinned to an old version will eventually stop working. That includes custom apps built by a previous agency and long-forgotten integrations with your ERP or fulfilment provider. Part of what a retainer buys is somebody tracking that calendar. If you do not want a retainer, at minimum have someone diarise the deprecation schedule, because the failure arrives without warning.
