Shopify builds and supportfrom the developerbehind the apps.

Our estimates are ¥500k+ for a new build, ¥800k+ for migration or redesign, ¥100k+ for theme changes, ¥300k+ for custom apps or Shopify Functions, and ¥100k+ per month for ongoing support (all excluding tax). Shopify subscription and app fees are separate.

A new build typically takes 2–3 months from agreement to launch. Migrations and custom features depend on data volume and scope, so we'll give you an estimate during the consultation.

Yes. We first review the store (theme, installed apps, how much custom code there is), then tell you what we can do and what it costs.

A Pepin developer handles everything directly, from the consultation through design, build and ongoing support. The person doesn't change midway. We'll tell you when we can start during the consultation.

We set up the store in your name and hand over admin access, theme code and setup documents. The Maru apps are public App Store apps, so you can keep using them after the contract ends (each app's monthly fee is separate).

It depends on the app. Store-specific apps built only from extensions, such as admin or checkout UI extensions and Shopify Functions, can run on Shopify without a server (apps that include Functions require Shopify Plus). If a server is needed, we decide together whether you contract it in your name or we operate it, and the cost is included in the quote.

Functions inside apps published on the App Store work on every plan. Custom apps built for a single store can only use Functions on Shopify Plus. For stores on other plans, we suggest an approach that fits the plan, such as combining existing apps or building it in the theme.

No. We only suggest them when they fit. If another app or a theme setting does the job, we'll recommend that instead.

No. You can start and stop month to month. From ¥100k per month (excl. tax), it includes up to 8 hours of work, a monthly meeting and chat support.

Yes. During the build we set up structured data, page speed and the structure of product page copy. After launch, the monthly plan keeps improving the store based on search data. We don't guarantee rankings or placement in AI search.

Yes. Meetings are held online, so we work with clients anywhere in Japan.

Yes. We also take on web service planning and development, and technical consulting. We build and run COSMA, a cosplay marketplace, ourselves.

You may be able to claim it as website costs under the Small Business Sustainability Subsidy. In round 20, the rate is 2/3, website costs are capped at ¥300k, and they can't be the only item in an application. Costs contracted before the grant decision aren't covered, so the build starts after the decision. You apply yourself, and we provide the quote and build description (we don't write applications). We aren't registered as an IT Introduction Support Provider, so the IT Introduction Subsidy (Digitalization and AI Adoption Subsidy) can't be used with us. We can't promise selection.
