We support brands that need custom Shopify development beyond default themes and standard app setups. Agencies can also bring us in as a white label Shopify development partner and ship client stores under their own brand.

Custom Shopify development is writing code for features that a theme and App Store apps don’t cover: custom sections in Liquid, product and pricing logic, checkout changes, integrations and private apps. It works on standard Shopify plans as well as Shopify Plus.
Usually when apps start to conflict, slow the store down or still don’t match how you sell. Common triggers are complex product configuration, bundles and subscriptions with custom rules, multi-market catalogs and ERP or warehouse data that has to sync both ways.
Most custom Shopify projects at SPLIT Development take 4 to 12 weeks. Smaller features and fixes usually ship within 2 to 5 business days. Timing depends on the integrations involved, the amount of theme work and the number of review rounds.
Custom Shopify development at SPLIT Development costs $8,000 to $12,000 for most projects. Store builds start at $4,000 and Shopify Plus projects at $12,000. The final price depends on the features, integrations and design work involved.
No. Most custom features work on any Shopify plan: Odyssey and KXKS run custom builds on standard Shopify. Shopify Plus matters when you need checkout customization, native B2B features or several storefronts under one account.
Often, yes. When several paid apps cover one workflow, or an app slows the storefront, the same logic can be built directly into the theme or as a private app. SPLIT Development reviews your app stack during discovery and tells you which apps are worth replacing and which are cheaper to keep.
