What you get
Shopify Plus agency, done properly
Shopify Plus can make sense when your current store is slowing down checkout changes, wholesale sales, international growth, or operations. Bytecode helps you decide what belongs on Plus and what should stay simple.
We build and migrate Plus stores with Checkout Extensibility, Shopify Functions, B2B setup, expansion stores, Flow automation, and launch-day readiness. You work with a New York development studio led by founder and lead developer Tapabrata Goswami.
Plus upgrade planning
We review your current Shopify setup, sales channels, apps, checkout needs, B2B plans, and operational blockers. Then we map which Plus features support the business case.
Checkout Extensibility
We help you move checkout customizations to Shopify’s supported Checkout Extensibility model. That can include checkout UI work, validation, analytics handoff, and app cleanup.
Shopify Functions
We build Shopify Functions where app settings are not enough. Common use cases include discount logic, delivery rules, payment rules, and cart or checkout validation.
B2B commerce setup
We configure B2B on Shopify Plus around how your buyers actually order. That can include company accounts, catalogs, payment terms, pricing rules, and approval flows.
Expansion stores
We plan expansion stores for regional, wholesale, or brand-specific storefront needs. The goal is clear ownership, shared patterns, and fewer duplicate mistakes.
Flow and launch readiness
We use Shopify Flow to reduce manual work around orders, customers, inventory, and fulfillment handoffs. Before launch, we test redirects, checkout, payments, tracking, search, and inventory behavior.

FAQ
Questions, answered
When should a brand move to Shopify Plus?
Not every brand needs Shopify Plus. It is worth considering when checkout control, B2B selling, automation, expansion stores, or operational limits are starting to cost you time or margin. We help you connect the upgrade decision to specific business needs before building.
Can we stay on standard Shopify instead?
Often, yes. Plus is worth it when checkout control, B2B, expansion stores or automation are costing you time or margin — not just because revenue grew. If the upgrade would be premature, we will say so. Our guide to Shopify vs. Shopify Plus covers the signs.
Can you help with Checkout Extensibility?
Yes. As of 2026, Shopify directs checkout customization toward Checkout Extensibility rather than older checkout customization patterns. We can review what you have, identify risky customizations, and rebuild the needed pieces using supported checkout tools.
What can Shopify Functions do for us?
Shopify Functions can handle custom backend logic for parts of checkout and commerce behavior. That includes use cases like discount rules, delivery options, payment method rules, and cart or checkout validation. We use Functions when native settings or apps do not fit the rule you need.
Do you set up Shopify Plus B2B?
Yes. We can help set up B2B structures such as company accounts, catalogs, payment terms, and buyer-specific ordering rules. We also look at how B2B affects fulfillment, customer service, reporting, and your existing DTC operations.
How do you reduce launch risk?
We plan redirects, sitemap cleanup, checkout testing, payment testing, inventory checks, analytics handoff, and app behavior before launch. For migrations, we pay close attention to product and collection URLs, schema, and tracking. The goal is to catch operational issues before customers do.
