If our company runs 3 separate brands, do we need 3 separate Shopify Plus contracts at $2,300/month each, or can one contract cover all 3?

The answer most people expect, and why it is wrong

The expansion-store allowance is the fact everyone reaches for, and it is genuinely the fact most people miss. Shopify publishes it plainly: "Your main store and 9 expansion stores are included as part of your monthly platform fee" (per shopify.com/plus/pricing, September 2026). Ten stores, one fee. It looks like it settles the question.

It does not, because expansion stores come with published eligibility criteria that three separate brands cannot meet. Shopify's own wording, under "Eligibility requirements for expansion stores on standard Shopify Plus plan contracts," is that expansion stores must adhere to all of the following:

• "Be extensions of the main brand."
• "Be identical to the main brand with respect to store name and other branding."
• "Carry the same types of goods and services as the main brand."
• "Have a billing currency set to USD or INR."

(per Shopify Help Center, September 2026)

Three separate brands, by definition, fail the second criterion and usually the first and third as well. Expansion stores are built for the same brand in a different country, a different language, a different currency, a B2B channel or a physical location. They are not built for a portfolio.

What Shopify actually offers instead, named

Shopify publishes the alternative in the same document: "If your proposed store doesn't meet the expansion store criteria, then you might be eligible for a multi-brand agreement, which allows multiple brands under one organization but requires each brand to have its own separate Shopify Plus plan subscription" (per Shopify Help Center, September 2026).

So the real answer is neither of the two options in the question. It is a third shape:

The multi-brand agreement buys you one commercial relationship, one organization, and centralized user and billing management. It does not buy you one subscription fee. Budget three.

The arithmetic Shopify does publish

Here is every Plus figure published as of September 2026, and nothing else:

Three Plus subscriptions on 3-year terms is $6,900 a month, or $82,800 a year, in platform fees alone. On 1-year terms it is $7,500 a month, or $90,000 a year. Those are floors, not totals, and the next section is why.

The multiplier that costs more than the contract question

The contract question is the cheap one. What actually multiplies across a portfolio is everything that bills per store, and Shopify is explicit about two of them.

Apps. "Apps are billed on a per-store basis rather than for the entire organization" (per Shopify Help Center, September 2026). Three brands running the same twelve-app stack pay for thirty-six subscriptions. Our per-store app billing record notes that no App Store listing publishes an organization-wide license, because a subscription is charged per store install, so portfolio pricing has to be negotiated app by app (Deploi decision record, September 2026).

Themes. "Theme licenses are required for each individual store, and a license can't be shared across stores" (per Shopify Help Center, September 2026). Shopify's theme licensing rule is the same one: "When you purchase a theme from the Shopify Theme Store, that theme is licensed exclusively to the store where the purchase was made," and "a theme can only be used on one store at a time" (per Shopify Help Center, September 2026).

The licence itself is small money. Our theme-licensing record caps the licence thinking at roughly $2,500 across five stores and puts the real repeat cost in per-store customization, not in the licence line (Deploi decision record, September 2026). The point is not the $200 to $500. The point is that everything shaped like a per-store licence repeats three times, and the app stack is where that gets expensive.

Two things Shopify does not publish, stated as gaps

The variable platform fee has no published percentage. Shopify says only that "For more complex, higher-volume businesses, there might be a variable platform fee based on your revenue and business model, which differs for B2B and D2C companies" (per Shopify Help Center, September 2026), and on the Plus pricing page, "More complex, higher volume businesses switch to a variable platform fee based on their revenue and business model." No percentage, no GMV threshold and no cap appears on either page. We will not quote one. A percentage circulating in agency content is somebody's contract, not a published rate, and quoting it as a fact is how a budget gets built on a number nobody can point at.

Card rates are published as a starting point, not a quote. The Plus plan card on shopify.com/pricing reads "Card rates from 2.25% + 30¢ USD," and the comparison table on the same page lists the same 2.25% + 30¢, while shopify.com/plus/pricing publishes no rate at all, saying only that "Card rates vary by country" and directing readers to sales (all September 2026). Treat 2.25% as the list starting point, and get your own rate in writing from sales before it enters a model.

What actually decides one contract or three

Run these four tests before you talk to Shopify. They decide the shape.

1. Legal entities. Do the three brands sit in separate legal entities with separate books? Note that this is separable from the store question: Shopify Plus and Enterprise organizations can "sell from multiple entities in a single store both online and using Shopify POS with Shopify Payments," where "Each entity has its own Shopify Payments account, payout currency, and bank account" (per Shopify Help Center, September 2026). Entity separation does not by itself force separate stores.
2. Catalogs. Do the brands share SKUs, or are the catalogs genuinely disjoint? Shared inventory across separate stores is the hard problem, because "Store settings, products, collections, and inventory aren't synced between stores. They don't share data by default" (per Shopify Help Center, September 2026). A shared warehouse behind three stores needs an inventory system that sits above all three.
3. Payment processing. Do the brands need separate merchant accounts, separate payout bank accounts and separate chargeback exposure? If yes, that is a real driver, and the multi-entity feature above is the mechanism to check before you assume it needs three stores.
4. Staff separation. Does brand A's team need to be unable to see brand B's orders, customers and revenue? Organization settings manage "users and billing centrally across all stores" (per Shopify Help Center, September 2026), which helps administration and is exactly what you have to configure carefully when separation is the requirement.

If all four answers are "separate," you have three businesses and you should expect three subscriptions under one organization. If three or four answers are "shared," look hard at Shopify Markets and multi-entity on a single store before you commit to a store count you will be paying app subscriptions against for years.

When NOT to split into three stores

• When the brands share a catalog. You will build and maintain inventory sync forever.
• When the split is a marketing preference, not an operating fact. Different domains and different storefront theming do not require different stores.
• When only the legal entity differs. Multi-entity selling inside one store exists on Plus and Enterprise for exactly this case.
• When nobody has priced the app stack three times. That number is usually larger than the platform fee difference, and it is the one that surprises people in month four.
