A Plus build is mostly everything behind the theme.
Storefronts are the easy part. What determines whether a Plus migration succeeds is the catalog, the ERP integration, and the order data you have to carry across without losing it.
What a Plus project consists of
Most Shopify Plus work arrives described as a redesign and turns out to be a data project. The theme is a few weeks. The catalog reconciliation, the ERP and OMS integrations, the historical order migration, and the redirect map for a URL structure that changes shape are the rest of it, and they are where a replatform goes wrong.
We scope those first. Before anything is committed, we inventory the catalog, the integrations that touch it, and the volume of order history that has to survive the move. That inventory is what the estimate is built from, which is why the price holds.
We are a Shopify Plus Partner, which gives Plus-tier access for builds, replatforms and the checkout extensibility work that Plus alone permits.
- Catalog and variant reconciliation before the theme is touched
- ERP, OMS and 3PL integration with retries that do not double-post
- Historical order and customer migration, verified by reconciliation
- Redirect maps built from the live URL set, not from the sitemap
What Plus Partner status means
Shopify started the Plus Partner program in 2016. It recognizes agencies with a track record of building on the platform for high-volume merchants, and it is granted by Shopify rather than claimed. Koombea has held the status since 2018.
In practice it gets you three things. Plus-tier capabilities that the standard platform does not permit, checkout extensibility included. An escalation path when the constraint turns out to be Shopify rather than the code. And access to the Plus app and partner ecosystem when the right answer is to integrate something rather than build it.
Where Plus Earns the Upgrade
Multichannel selling
One catalog behind online, retail, marketplaces, and social, so stock and price are not reconciled by hand.
Integration headroom
Higher API limits and Plus-only endpoints, which is what makes real-time ERP and OMS sync viable at volume.
Checkout you can change
Checkout extensibility, which Plus alone permits, for B2B terms, custom validation, and payment routing.
Wholesale and B2B
Company accounts, price lists, and approval flows, without a second storefront to maintain.
Scale and security
Shopify carries PCI scope and flash-sale traffic, which removes two things you would otherwise own.
Support with a path
A named escalation route, so a platform-level blocker does not become a support ticket queue.
What we build on Plus
Replatform to Plus
Magento, WooCommerce and custom carts, moved with the order history intact.
ERP and OMS integration
NetSuite, SAP and the middleware between, with idempotent writes.
Checkout and payments
Checkout extensibility, Shopify Payments, and third-party processors.
Headless storefronts
Hydrogen and custom front ends where the theme layer is the constraint.
B2B on Plus
Company accounts, price lists and the approval flows wholesale needs.
StorefrontOS
Our commerce foundation, so the common surface is already built.
Why the replatform estimate usually moves
A Plus quote that moves after signature almost always moves for one of four reasons, and all four are discoverable before anyone commits.
- The catalog has more real variants than the export suggests, because configurable products expand on migration
- An integration nobody listed turns out to be load-bearing, usually tax, shipping or a returns portal
- Order history has to move, not just customers, because support needs it and the finance team needs it more
- The old URL structure does not map cleanly, so redirects become a project rather than a file
How this is priced
Commerce work is delivered by AI Pods against a committed scope, priced in story points and agreed before work begins. A replatform is estimated from the catalog and integration inventory, not from a page count.
Where StorefrontOS covers a surface you need, the point cost drops, because the foundation is already built and tested.
What you get that a theme shop cannot give you
You get a software company that does commerce work, not an agency that only does Shopify. On a replatform that difference shows up in the parts of your project which are not the store: your ERP wiring, your migration reconciliation, and the native app you will want six months later.
Your work runs through a CMMI-DEV/3 appraised process, which is an independent appraisal rather than a self-assessment. Products built here have been acquired by Google, Motorola Solutions, Facebook, and Skype.
- Your first store, or a multi-region Plus replatform, scoped the same way
- Your ERP, CRM, WMS and 3PL integrations, including the middleware between them
- Your order and customer history moved, then verified by reconciliation rather than spot check
- Your checkout extended where Plus permits it, including B2B terms and payment routing
- Your store as a native iOS and Android app, through StorefrontOS
- Your brand as a design system, when a purchased theme will not carry it
- Your team's hours, in English or Spanish, on Eastern time year round

With Shopify, I'm able to maintain speed while bringing new products or promotions to market, which allows me to stay innovative and at the cutting edge of my industry.
