Shopify Plus Agency for Growing Brands
A Shopify Plus agency builds and customizes stores on Shopify's enterprise plan: checkout extensibility, Shopify Functions, B2B wholesale channels, multiple storefronts and higher API limits. It is for brands with the order volume or complexity that the standard plans cannot handle. Brand Overture builds on Shopify and Shopify Plus from Phoenix for clients across the US and overseas.
Standard Shopify is holding the brand back
You moved to Shopify because it is reliable. Now the business has outgrown the plan. Checkout is the one page you cannot touch, and it is where most of the revenue leaks. Wholesale buyers email orders because there is no B2B portal. You want a second storefront for another country or brand and the admin cannot do it. Discount logic that fits your business does not exist in the discount editor.
Shopify Plus solves these problems. Most agencies that sell it either do not know how to use the extra capabilities or hand the work to a team you never meet.
How we build on Shopify Plus
We start by confirming you actually need Plus. Some stores do not, and we will say so. When Plus is right, we map the features to the problems: checkout extensibility for custom fields, upsells and branding in checkout; Shopify Functions for discount, shipping and payment rules written to your business logic; B2B for company accounts, price lists and net terms; expansion stores for new markets.
Then Terrence builds it. Checkout UI extensions and Functions are written and deployed to a development store first, tested with real order flows, then moved to production with a rollback plan. Theme work follows the same path. Integrations with your ERP, 3PL or PIM get a written data map before anyone writes a line of code.
You get a fixed scope and price in writing before the work starts, and one person answering your messages during it.
What changes for the business
Checkout works the way your buyers expect, with the fields, offers and trust signals your category needs. Wholesale customers order themselves at their prices. Promotions follow your rules, not the discount editor’s limits. New markets launch as stores you control from one admin. The team stops working around the platform and starts using it.

Heavy Pedal
Heavy Pedal is a cycling apparel brand we built on Shopify. The store had to handle apparel sizing across many styles and colors, present collections the way cyclists shop, and carry a brand look the sport takes seriously. It is the kind of catalog that grows into Plus features like checkout customization and Functions as volume climbs.
Pricing. No dollar figures on a web page can be honest without knowing your scope. After a free 30-minute call you get a fixed scope and price in writing before any work starts.
Questions about shopify plus.
Is Shopify Plus worth it for my store?
It depends on order volume and complexity. Plus pays off when you need checkout customization, B2B pricing, custom discount logic or multiple storefronts. If your store does not need those, we will tell you to stay on a standard plan.
How much does a Shopify Plus build cost?
Plus has its own platform fee from Shopify. Our development work is separate, and after a free 30-minute call you get a fixed scope and price in writing before anything starts.
What can you customize on Plus that you cannot on standard Shopify?
Checkout, mainly. Plus allows checkout UI extensions, custom fields and branding, Shopify Functions for discount and shipping rules, B2B company accounts and expansion stores. Standard plans lock most of that down.
Can you move my existing store to Plus?
Yes. Upgrading within Shopify keeps your theme, products and customers in place. The work is in using the new capabilities well: rebuilding checkout, adding Functions and setting up B2B or expansion stores with a rollback plan.
Do you work with our in-house team or other agencies?
Yes. Terrence can own the whole build or take the development pieces alongside your team, your marketing agency or your ERP vendor. Everything is documented so anyone can pick it up.
