Today on Shopify → On Shopify Plus ### What stays, what changes, what we build We sort every item into one of these three columns before we quote. #### Stays put same store Nothing to export or import. **Products** stay on the same store **Customers** keep their accounts **Orders** history untouched **Theme & apps** carry over as is #### Changes on Plus Same idea, upgrade-safe tools. **Checkout** extensions, not theme edits **Discount logic** becomes Functions **Wholesale** native B2B companies **Billing** Plus plan and fees #### We build new The work that makes Plus pay. **Checkout UI** extensions built **Functions** discounts, delivery, payment **B2B setup** companies and catalogs **Expansion stores** set up and synced Shopify vs Plus ### What actually changes when you move to Shopify Plus The upgrade itself is a plan change. The value is in a handful of features you only get on Plus, and only if someone sets them up. This is the list. Plus features and plan rules change. We check the current list with you in the audit. | Area | On your current Shopify plan | On Shopify Plus | | Checkout | Branding settings and apps in limited spots. Deeper checkout changes aren’t available. | Plus Checkout UI extensions across the checkout steps, plus custom Functions for discounts, delivery and payment rules. | | Custom logic | Public apps that use Shopify Functions. | Plus Your own custom Functions, built for your rules. Shopify Scripts are being retired, so any Scripts you have move to Functions. | | B2B | Wholesale apps or a second store. | Plus Native B2B: company accounts, locations, catalogs, price lists and payment terms on the same store. | | More stores | Each store on its own plan. | Plus Expansion stores under one organisation admin, for regions or brands. | | Automation | Shopify Flow is available on most plans. | Plus Launchpad for scheduled sales and theme switches, plus Flow connected to Plus-only triggers. | | Your data | Products, customers, orders, apps, theme. | Unchanged All of it stays. Nothing is exported or imported. | SEO ### Your URLs stay, your checkout grows On Plus nothing moves, so nothing needs redirecting. What changes is what sits behind the same URLs, plus any new market or expansion domains. **Same domain** No DNS change for the main store. **Checkout upgraded** Same URL, extensibility on top. **New markets** Local domains or subfolders as needed. **B2B on one admin** No second wholesale store to keep in sync. Worth it? ### Is Shopify Plus worth it for your store? Plus costs a lot more than standard plans, and the bill arrives whether you use the features or not. We meet stores that upgraded because they hit a revenue number and then changed nothing, which is the expensive way to do Plus. It pays when at least one of these is true: you’re running wholesale on a second store or a patchy app and want it in one admin; your checkout needs logic Shopify can’t do out of the box, like delivery rules by postcode or payment methods hidden for certain baskets; or you’re opening stores for new regions or brands. #### When we’d say wait If none of those apply and the reason is “it feels like the next step”, wait. A [conversion review](https://intelligizedigital.com/services/conversion-optimisation/) or [speed work](https://intelligizedigital.com/services/speed-optimisation/) on your current plan usually earns more for the money. When you do move, the upgrade needs no data migration, so you lose nothing by waiting until there’s a clear job for Plus to do. Upgrade when Plus has a job to do, rather than when you hit a revenue number. Our default advice Data to migrate **none** Downtime **none** Work that matters **checkout, B2B, expansion** Upgrade ### Upgrade day, step by step Week 1 #### Audit Every checkout customisation, app and script listed. Upgrade #### Plan change Store moved to Plus; nothing goes offline. Week 2–4 #### Build Extensions and Functions built on a dev store. Launch #### Publish Checkout extensions and Functions published. Launch +1 h #### Checks Test orders across markets, B2B and payments. Risks ### What can go wrong on a Plus upgrade Fewer moving parts than a full migration, but a live checkout is involved, so we treat it with the same care. ### High Scripts left running until they stop What goes wrong Shopify is retiring Scripts. Stores that wait end up rewriting discount and shipping logic in a hurry. What we do We inventory every Script, rebuild it as a Function on a development store, and run both side by side with test baskets before switching. ### Medium B2B prices leaking to retail What goes wrong A catalog assigned to the wrong company location, or a price list that also applies to guests, shows trade prices to the public. What we do We test with real logins for each buyer type, plus a logged-out session, before B2B goes live. ### Medium Checkout extensions and apps clashing What goes wrong Two apps adding blocks to the same checkout step can confuse customers or slow the page. What we do Every checkout block is placed in the checkout editor with a reason. We remove apps whose job a Function or extension now does. ### Low Expansion stores drifting apart What goes wrong Products and prices are edited in one store and forgotten in the other. What we do We set up catalogue sync, using Flow or a sync app, and decide which store is the source for each field. Pricing ### Shopify to Shopify Plus, priced up front Typical ranges.

Good answers are specific. - #### What will Plus let us do in 90 days? If the answer is vague, the upgrade can wait. A good answer names a checkout change, a B2B setup or a new store. - #### Which of our Scripts or apps become Functions? You should get a list, with what each one does today and how it will be rebuilt. - #### How will B2B buyers log in and order? Look for a clear plan for company accounts, catalogs, payment terms and how existing wholesale customers are invited. - #### What do we stop paying for? Apps replaced by Plus features should be named, so the extra plan cost is partly offset. Questions ### Shopify to Shopify Plus, answered Anything else, ask on the audit call.

[See all questions](https://intelligizedigital.com/faq/) ### Do we have to migrate our data to move to Plus? No. Shopify Plus is an upgrade of your existing store, so products, customers, orders, theme and apps stay where they are. Intelligize Digital focuses on what Plus changes: checkout, Functions, B2B and expansion. ### What happens to our checkout customisations? Checkout changes made in theme files are rebuilt as checkout UI extensions and branding settings, which are upgrade-safe and editable in the checkout editor. ### Can Functions replace our discount apps? Often, yes. Tiered, bundle and conditional discounts, plus delivery and payment rules, can be built as Shopify Functions running inside Shopify. ### Is B2B worth it on Plus? If you run a wholesale store or a wholesale app, native B2B companies, catalogs and payment terms usually let you serve both on one store. ### Will the store go offline during the upgrade? No. The plan change and the publishing of extensions happen on the live store without downtime; new work is built and tested on a development store first. ### How long does a Shopify Plus upgrade take? The plan change is quick. The work that makes Plus useful, such as checkout extensions, Functions and B2B, usually takes a few weeks and is built on a development store first. ### Do Shopify Scripts still work on Plus? Shopify is retiring Scripts in favour of Functions. If you have Scripts, we rebuild them as Functions and test both side by side before switching. ### Can we run wholesale and retail on one Shopify Plus store? Yes. Native B2B lets trade buyers log in to see their own catalogs, prices and payment terms, while retail customers see the normal store. Other routes ### Going the other way, or somewhere else?
