Shopify Plus development for brands that have outgrown the theme.

There are two costs to plan for, and they are easy to mix up. The first is the Shopify Plus licence, which starts at roughly $2,300 a month. The second is the build: the engineering that makes checkout, discounts, B2B and integrations behave the way the business needs. The licence is predictable. The build is where budgets go wrong.

For a move onto Plus from another platform, most migrations run eight to sixteen weeks from kickoff to cutover. The sequence is the same every time: data and URL mapping, a rehearsal migration, build and parity QA, then cutover and hypercare. An upgrade from standard Shopify moves no catalogue, but checkout, discount and B2B logic are rebuilt against different primitives, so the testing still takes real time.

On price, our guide to hiring a Shopify Plus developer sets out what we see in contracts: specialist Plus agencies bill a blended $150 to $300 an hour, and fixed-price engagements such as an audit, migration or replatform typically fall in the $25K to $150K band. Treat that as market signal, not a quote.

For the licence side on its own, by stage and line by line against Advanced, see the full breakdown of Shopify Plus pricing.

Where a project lands depends on a short list of things:

• Checkout and discount logic. How many Scripts, discount rules and checkout customizations have to be restated as Functions and checkout extensions, and how closely finance needs the old behaviour matched.
• B2B rules. Company accounts, price lists, payment terms, approval flows and location-level ordering, and how many places those rules live today.
• Integrations. Every ERP, 3PL, PIM, OMS and CRM connection that has to keep working, and which system owns each record.
• The app stack. Which apps stay, which are replaced by custom code, and which were only ever workarounds.
• Markets. Currencies, languages, tax treatment and market-specific catalogues, each with its own tests.
• History that has to move. Customers, orders and, for B2B, the invoice history buyers expect to find in their account.

We do not quote from a page count or a product count. We scope from a system map first, write the scope down before delivery starts, and rehearse before any cutover, so launch day is a verification rather than a discovery.

If you are not yet sure Plus is the right move, start with the question in the FAQ below: are the limits you are hitting platform limits or build problems? The Plus licence fixes the first kind. Only engineering fixes the second, and it is cheaper to learn which one you have before you sign either contract, the licence or the build.

The way we approach Plus work is written down in public. Read it before you shortlist anyone, including us.

• Shopify Plus review: when it is worth it covers what Plus actually delivers, the patterns we find broken on Plus stores, and where it falls short of the alternatives.
• Hiring a Shopify Plus developer in 2026 sets out the skills that predict performance, the interview questions that surface them, the in-house, contractor and agency tradeoff, and current rate ranges.
• Shopify Scripts to Functions is the technical guide to porting checkout and discount logic, with test plans and cutover sequencing.
• Importing old invoices into a Shopify B2B account is the playbook for schema mapping, staged imports and reconciliation of legacy invoice history.
• Shopify ERP integration: ownership, failures and go-live tests explains which system owns each record, what happens when a sync fails, and the tests that prove the integration can carry daily operations.
• What Shopify Plus really costs each month separates the licence, the variable fee and the build, and names the four numbers to get in writing before you sign.
• Ten Plus stores worth copying takes one pattern from each, across B2B, markets, checkout, Functions and retail, and says which ones need Plus.

If you are moving onto Plus from another platform, the Shopify migration page sets out the acceptance standard every cutover is held to.
