Before you scope

What depends on your Shopify plan, theme and apps

Not everything is a matter of development time. Some functionality depends on your Shopify plan, some on the theme you use, and some needs a paid app. We check these before quoting, so you know what is possible and what it costs to run.

Your Shopify subscription, any paid theme and app subscriptions are billed to you by Shopify or the provider. They are not part of our project fee.

Common examples

  • Checkout changes and some B2B features depend on your Shopify plan
  • Filtering options and variant swatches vary by theme and how products are set up
  • Reviews, subscriptions and bundles usually need an app
  • Migrating order history or reviews may need a migration app

How we work

Our Shopify Development Process

Five stages, with a clear review point before launch.

  1. 01

    Discovery

    We review your goals, products and current store, then send a written scope and quote.

  2. 02

    Design

    We agree the theme approach and page plan with you before the build.

  3. 03

    Development

    We build on a working or duplicate theme, using the products and content you supply.

  4. 04

    Testing & Launch

    We check mobile layouts and checkout, go live with your approval, and hand over documentation.

  5. 05

    Ongoing Support

    If you choose, we continue with agreed maintenance and improvements.

Timelines depend on scope, how ready your content is, and how quickly reviews come back. You get a project-specific timeline after discovery.

Why Flasin

How we work on Shopify projects

Stated as practices, because that is what they are.

Store, marketing and automation together

If you later add marketing or customer support, the work builds on a store we already know. You can also hire us for the store alone.

Testing before launch

Key pages and the path through checkout are tested on phone and desktop before anything goes live.

Custom code when apps are not enough

Shopify Liquid, APIs, webhooks and custom integrations are used where off-the-shelf apps do not meet the requirement — and not where an app does the job.

Clear ownership and documentation

Scope, integrations, credentials, handoff and maintenance responsibilities are defined before launch. The store, theme, content and domain stay in your name.

Careful with credentials

API keys and app tokens are scoped to what each integration needs and kept in configuration, never pasted into theme code.

Migrations planned, not rushed

Products, customers and URLs are mapped before a move, and old URLs are redirected so existing links and search visibility are not thrown away.

These are the practices we build to, not certifications Flasin holds. Payments are processed by Shopify and your chosen payment providers; Flasin never handles your customers' card details.

Optional additions

Add marketing or support when you need them

These are separate services with their own scope and fees. Your store project doesn't depend on them.

Digital marketing

SEO, AI search visibility, ads, email, social, conversion work and analytics.

Explore ecommerce marketing

AI chatbots

Answers to product and policy questions from your own information, with handoff to a person.
