The Shopify to Shopify Plus decision usually gets framed as a revenue threshold question. It isn't really. The number on the licence matters less than what the brand is trying to do that the standard plan won't let them do. Some brands hit Plus thresholds at $1.5M and benefit immediately. Some brands stay on Advanced past $20M because their use case fits. And as of April 2026, the goalposts moved again. Most "Plus or not" frameworks you'll read are out of date.

Here's how to tell which one you are, with the current capability lines and the current commercials.

What actually changes

The Shopify to Shopify Plus upgrade is not a re-platform. The data, admin, theme architecture, and core capabilities are the same. What changes is what the platform unlocks.

Capability unlocks (Plus-only as of May 2026):

  • Checkout UI extensions for the information, shipping, and payment steps
  • Custom Shopify Functions (your own code, deployed via Shopify CLI)
  • Unlimited B2B catalogs, direct catalog-to-company assignment, partial payments, deposits
  • Up to 9 expansion stores under one organisation
  • Unlimited staff accounts
  • Higher API rate limits
  • Dedicated Merchant Success Manager and 24/7 priority support
  • Launchpad for scheduled sales and theme changes

What doesn't change:

  • Your domain, theme, admin, or product data
  • Most apps in your stack
  • Your storefront URL structure (unless you actively restructure)
  • Your SEO surface (unless you change URLs)

The upgrade itself is a configuration change handled by Shopify. The work is in adopting the capabilities, not migrating the platform.

What changed in April 2026 (and why old guides will steer you wrong)

Two things shifted in the last six weeks that broke most of the existing "should we move to Plus" content on the internet.

1. B2B opened up to lower plans. On April 2, 2026, Shopify extended core B2B features to Basic, Grow, and Advanced. That includes company profiles, up to 3 custom catalogs, volume discounts, quantity rules, vaulted credit cards, and payment terms. Plus still owns the deep B2B stack (unlimited catalogs, customer-level pricing, partial payments, deposits), but the entry-level B2B paywall is gone.

2. The pricing model is hybrid, not flat. Shopify Plus runs as a floor plus Variable Platform Fee (VPF) structure. $2,300/month is the floor. B2B GMV is charged at 0.18%. D2C GMV is charged at 0.35%. You pay the higher of the floor or your total VPF. This isn't new in 2026, but most agency content still treats it as a flat $2,300/month, which is wrong above ~$7.9M in annual D2C revenue.

We've broken the pricing model down properly in Shopify Plus pricing in 2026: how the variable platform fee actually works. Read it before you sign anything.

Why most "Plus or not Plus" framings get it wrong

The common framing is "you need Plus when you hit $X revenue." It's a useful shorthand but misses the actual decision driver, which is capability, not revenue.

A $1.5M brand running B2B with company-specific catalogs and partial payments needs Plus because those features stay Plus-only. A $25M brand running clean DTC with no B2B, no checkout customisation, and no multi-store probably gets nothing material from Plus.

The right question isn't "what's our revenue?" It's "what are we trying to do that Advanced won't let us do, and what does that capability cost on Plus once we factor in VPF?"

The four capability triggers that actually justify the upgrade

In practice, four capability needs drive most upgrade decisions in 2026.

Trigger 1: B2B beyond the basics. With the April 2026 changes, Advanced handles entry-level B2B natively: company profiles, three custom catalogs, volume pricing, quantity rules, payment terms. The Plus B2B trigger now sits at the next layer. You need Plus when you require unlimited or customer-specific catalogs, direct catalog assignment to companies or locations, partial payments and deposits, or B2B checkout customisation. If your wholesale is "fifty buyers on a shared catalogue with tiered pricing," Advanced handles it. If your wholesale is "hundreds of accounts on custom price lists with multi-step approval and deposit invoicing," you need Plus.

Trigger 2: Checkout customisation Advanced can't reach. Checkout UI extensions for the information, shipping, and payment steps remain Plus-only. Branding API access for deep checkout design is Plus-only. If you need custom fields at checkout, conditional payment method logic, multi-step flows, or post-purchase upsells with deep customisation, Plus is the answer. Checkout extensibility on lower plans handles basic branding plus Thank You and Order Status page extensions, which covers a surprising amount but not the core checkout flow.

Trigger 3: Multiple storefronts that share inventory or branding. Plus brands run up to 9 expansion stores under one organisation. Useful for international expansion (one store per country with shared inventory), DTC and B2B as separate stores, brand portfolios where different brands share an organisation, and outlet or sample-sale stores. Doable on Advanced with multiple separate Shopify accounts, but less integrated and harder to operate.

Trigger 4: Custom Functions logic Advanced won't allow. Public Functions apps from the App Store work on every plan. Custom Shopify Functions (your own code, deployed via Shopify CLI) is Plus-only. If you need bespoke discount logic, custom shipping rate calculations, payment method filtering, or cart transforms that no off-the-shelf app does, you need Plus. Note: with Shopify Scripts being killed on June 30, 2026, anyone with active Scripts has roughly six weeks to migrate.

If you tick none of these triggers, the upgrade probably doesn't pay back. If you tick two or more, it usually does.

The Plus pricing structure (and why old "$2,300/month" math is wrong)

Shopify Plus pricing in 2026 has three numbers that matter:

  • Floor: $2,300/month on a 3-year term, $2,500/month on a 1-year term
  • VPF on B2B GMV: 0.18%
  • VPF on D2C GMV: 0.35%

You pay whichever is higher: the floor or your total monthly VPF. The fee is capped at $40,000/month, which only matters at ~$100M+ annual scale.

Two practical consequences:

  1. Pure D2C brands cross the floor at ~$7.9M annual revenue. Above that, every additional dollar of D2C revenue costs 0.35% in platform fees.
  2. B2B-heavy brands save material money. A brand at $10M with 50% B2B pays roughly the floor. The same brand at $10M pure D2C pays ~$35K/year in VPF.

This changes the upgrade math significantly, especially for brands with material B2B mix. We've worked through the math at six revenue levels with different B2B/D2C splits in the commercials piece.

Transaction fee gap (still real). On Advanced, third-party payment gateway fees apply at higher rates. On Plus, those drop to 0.20%. For a brand processing $10M+ per year through non-Shopify Payments gateways, the fee differential alone is $30K to $80K per year and contributes to the upgrade math.

What the upgrade actually costs (beyond the licence)

The licence delta is one line. The real year-one number is bigger.

Licence delta. Plus VPF minus Advanced's $399/month. Variable based on GMV mix.

Ecosystem premium. Some agencies and consultants price Plus engagements differently from Advanced. Some apps have Plus tiers. Some integrations cost more on Plus. Plan for 10 to 30% premium across the stack on similar work.

Capability adoption work. Setting up advanced B2B, configuring checkout extensions, building Shopify Functions, restructuring for multi-store. Usually $20K to $80K of agency work depending on which capabilities you're adopting. The work pays back through the unlocked capability, not as a sunk cost.

Optional retainer. Brands actively building on Plus often run a $5K to $20K per month retainer with a Plus partner for ongoing checkout extension work, B2B optimisation, and Functions development. Not required, but common.

Total year-one investment for a brand actively adopting 2 to 3 Plus capabilities usually lands at $40K to $150K above the licence delta.

The upgrade itself: not a re-platform, but not nothing

Because Shopify to Shopify Plus is the same platform, the data and theme migrate cleanly. But the upgrade still has implications.

Domain and URL implications. If you're consolidating multiple Advanced stores into a Plus organisation with expansion stores, URL structures change. If you're moving to Shopify Markets for the first time, regional URL structures may change. Both cases need a 301 redirect map.

B2B setup. If you're moving from a third-party B2B app on Advanced to native Plus B2B, customer accounts, organisation hierarchies, and catalogue pricing all need to be set up. Customer data migrates but the structure is different. If you're already on Advanced native B2B post-April 2026, the upgrade just unlocks the deeper feature set.

Checkout customisations. Checkout.liquid is fully deprecated as of the August 28, 2025 deadline, and Shopify has been auto-upgrading stores since January 2026. The August 26, 2026 deadline for additional scripts on all plans is still coming. If you had custom checkout work on Advanced via apps or legacy code, the move to checkout extensibility is a rebuild.

Scripts to Functions. Shopify Scripts hits a hard cutoff on June 30, 2026. Any Plus store still running Scripts-based discount, shipping, or payment logic has roughly six weeks to migrate to Functions. If you're upgrading from Advanced to Plus and considering Functions for the first time, plan the work alongside the upgrade rather than treating it as a separate project.

Apps and integrations. Most apps work on both. Some have Plus tiers with additional features that need configuring. Some integrations need re-authentication or repointing. Plan a 1 to 2 week post-upgrade audit.

Payment processing. If you're moving payment gateways at the same time (common when migrating to Shopify Payments), customer payment tokens may not transfer. Subscriptions need attention specifically.

SEO surface. If domain or URL structures change, the SEO work is real even on the same platform. See how to preserve SEO when migrating to Shopify Plus for the playbook.

When the upgrade is the wrong move

Four patterns suggest holding on Advanced for now.

Pattern 1: Clean DTC, no capability triggers. $5M to $20M brand running a clean direct-to-consumer business with no B2B, no checkout customisation needs, single store, simple discounts. Plus is a cost without a return. Stay on Advanced and put the budget into growth or operations.

Pattern 2: Entry-level B2B only. Post-April 2026, if your B2B is under 50 accounts, sits within 3 catalogs, and doesn't need partial payments or deposits, Advanced handles it natively. The upgrade to Plus is no longer triggered by B2B alone.

Pattern 3: Pre-product-market-fit. Brands still figuring out their core proposition. The Plus capabilities reward brands that know what they want to build. Brands that don't know yet should stay flexible.

Pattern 4: Migration imminent. If you're planning a re-platform to Plus from another platform within 6 months, upgrading from Advanced first usually doesn't make sense. Wait and migrate directly.

When the upgrade is overdue

Four patterns suggest the upgrade is already overdue.

Pattern 1: B2B has outgrown the 3-catalog limit. If you're hitting the 3 active B2B catalog limit on Advanced, or you need customer-specific pricing rather than tiered pricing, or you need partial payments and deposits, the workflow tax is significant. Plus B2B pays back.

Pattern 2: Checkout customisation requests piling up. If product, marketing, and ops keep requesting checkout changes to the information, shipping, or payment steps that "we can't do on Advanced," the velocity tax is real. Checkout extensibility on Plus turns those into a few weeks of work.

Pattern 3: International growth requiring multi-store. If you're running 3+ Advanced stores for different countries and inventory sync is becoming a maintenance project, expansion stores under a Plus organisation are usually more efficient.

Pattern 4: Recurring app subscriptions above $30K per year. If you're paying a stack of apps to do things Plus does natively (advanced B2B, checkout customisation, custom Functions logic), the app stack is often more expensive than the upgrade plus the rebuild work.

Where to start

If you're evaluating the Shopify to Shopify Plus upgrade, the first step is a capability audit. We document which Plus features map to your actual business requirements and run the year-one cost math against your current Advanced spend, using the actual VPF structure rather than the flat $2,300/month assumption.

Frequently asked questions

When does upgrading from Shopify to Shopify Plus pay back?

The decision is rarely about revenue thresholds. It's about specific capability triggers: B2B beyond the 3-catalog Advanced limit, checkout UI extensions for information, shipping, or payment steps, expansion stores for multi-region or multi-brand, or custom Shopify Functions. If two or more apply, the upgrade usually pays back inside 12 to 18 months. If none apply, the upgrade is a cost without a clear return.

Is B2B still a Plus-only feature?

No. As of April 2, 2026, Shopify opened native B2B to Basic, Grow, and Advanced plans. Non-Plus plans get company profiles, up to 3 custom catalogs, volume discounts, quantity rules, vaulted credit cards, and payment terms. Plus still exclusively owns unlimited catalogs, direct catalog-to-company assignment, partial payments, and deposits. The Plus B2B trigger now sits at "B2B beyond the basics," not "you have B2B."

How much does Shopify Plus actually cost in 2026?

Plus runs as a floor plus variable platform fee. The floor is $2,300/month on a 3-year term or $2,500/month on a 1-year term. The VPF is 0.18% of B2B GMV and 0.35% of D2C GMV, and you pay the higher of the floor or the VPF total. The fee is capped at $40,000/month. Plus capability adoption work usually adds $20K to $80K in year one. Full math with worked examples is in our commercials piece.

How is upgrading from Shopify to Plus different from a real migration?

This isn't a re-platform. The data, admin, theme architecture, and core capabilities are the same. What changes is what the platform unlocks: deep checkout customisation via UI extensions, advanced B2B, expansion stores, custom Shopify Functions, higher API rate limits, and dedicated support. The upgrade itself is a configuration change handled by Shopify. The work is in adopting the new capabilities, not migrating data.

Do I need to redo my theme if I upgrade to Shopify Plus?

No. Existing Liquid themes work on Shopify Plus without modification. The upgrade is a capability switch, not a theme requirement. Most brands take advantage of the upgrade to refactor or refresh the theme, but it's not required. If you're moving from Liquid to Hydrogen headless, that's a separate, larger project worth scoping independently.

Will my apps still work on Shopify Plus?

Yes, almost universally. The Shopify App Store apps work on both Shopify and Shopify Plus. Some apps have Plus-tier pricing or additional features unlocked at the Plus level. The migration is a good moment to audit the app stack: most brands enter migration with 30 to 50 apps and exit with 12 to 20 by retiring redundant tools.

Can I downgrade from Shopify Plus back to Advanced?

Technically yes, but you'd lose any Plus-only features you've built on. Checkout UI extensions, custom Shopify Functions, advanced B2B configuration (unlimited catalogs, partial payments, deposits), and expansion stores all become inaccessible on Advanced. Most brands that upgrade don't downgrade because the operational lock-in builds quickly.

Should I just stay on Shopify Advanced and use third-party apps for the Plus features?

For some capabilities, yes. With native B2B now on Advanced, the gap closed materially in April 2026. Apps for advanced checkout customisation, custom Functions logic, and multi-store can still work on Advanced with monthly subscription costs. The math turns when your app subscriptions for Plus-equivalent features exceed $30K to $40K per year. At that point, the Plus upgrade plus capability adoption work usually costs less than continuing on Advanced.

TLDR Summary
  • The upgrade is a capability switch, not a re-platform. Same data, admin, and theme architecture.
  • In April 2026 Shopify opened B2B to Basic, Grow, and Advanced. That kills the old "B2B equals Plus" trigger for entry-level wholesale. Plus is now only needed for unlimited catalogs, customer-level pricing, partial payments, and deposits.
  • Plus pricing is hybrid: $2,300/month floor plus a Variable Platform Fee of 0.18% on B2B GMV and 0.35% on D2C GMV. You pay the higher of the two. Full math in how the variable platform fee actually works.
  • Real triggers for Plus in 2026: deep B2B beyond the basics, checkout UI extensions, expansion stores, and custom Functions.
  • Total year-one investment for a brand actively adopting 2-3 Plus capabilities lands at $40K to $150K above the licence delta.
