Shopify Plus development that earns back its platform fee
We replatform growing brands to Shopify Plus and build on Plus features only where they pay for themselves. Fixed price, named team, 8 to 12 week launches with a redirect map that protects your rankings.
140 stores built, 8 years on the platform, senior engineers only
Codioo is a Shopify Plus development agency that replatforms established brands without losing SEO, speed or trading days. A Plus build with us runs 8 to 12 weeks, starts at $9,000, and ends with a fixed scope delivered by named senior engineers. We decide Plus feature by feature: you get checkout extensibility, Flow automation and multi market tooling where they earn their keep, and honest advice where standard Shopify is enough.
What we build on Shopify Plus
Plus is not a theme with a badge. It is a different contract: different limits, different checkout, different automation. These are the builds that justify it.
Full replatforms to Plus
Catalogue, customers, orders, reviews and content migrated from Magento, WooCommerce, custom stacks or another Shopify plan, with a one to one 301 redirect map and a 60 day indexation watch after launch.
Checkout extensibility
Checkout blocks and Shopify Functions for upsells, validation rules, delivery options and loyalty redemption built on the official APIs, so you stay upgrade safe instead of patching scripts.
Multi market architecture
One store, many markets: localised catalogues, currencies and duties through Shopify Markets, or separate stores stitched with a shared inventory when the business needs that shape.
Flow automation programs
The repetitive work your team does by hand, order tagging, fraud triage, replenishment alerts, customer re engagement, built as Flow templates your staff can read and adjust.
B2B on Plus
Company accounts, catalogues per customer group, net terms and minimum orders, plus the frontend patterns that make a B2B store pleasant for a buyer who orders every Monday.
Launchpad and peak season
Flash sale pages, scheduled campaigns and inventory holds configured for Black Friday, with a load tested checkout and a runbook your team can execute without us.
When do you need Shopify Plus development?
Plus costs more per month, so the trigger matters. Any one of these signals usually justifies the move.
You are hitting plan ceilings
Staff seats, API call limits or variant caps are interrupting real work more than once a month. Plus raises all three.
You need to change checkout
Upsells at checkout, custom validation, delivery promises. On standard plans checkout is locked; on Plus it is extensible.
GMV makes the fee cheaper
Plus negotiates payment processing rates. Above a threshold the discount on processing outweighs the platform fee. We will help you do that math with your real numbers.
You sell across borders
Multiple currencies, languages and duty regimes from one admin. Markets handles most of it; Plus handles the edge cases.
Your team repeats the same clicks
Order tagging, approval chains, stock alerts. Flow on Plus removes work your operations team does daily.
You are leaving Magento or custom
Maintenance cost and release risk are climbing while the store stands still. A Plus replatform ends the security patch treadmill.
How we run a Shopify Plus replatform
One question deserves a number instead of an opinion: what does Plus actually cost to run? The platform fee is Shopify's side of the contract, negotiated per merchant, and the processing rate discount is yours. At roughly $1M annual GMV the processing savings usually cover the fee difference; at $5M they exceed it several times over. The audit runs this arithmetic with your real numbers before anyone signs anything, because recommending Plus to a brand that standard Shopify serves well is the most expensive advice an agency can give for free.
A Plus replatform fails in predictable places: data that does not map cleanly, redirects discovered after launch, and a team that learns the new admin on go live week. Our process is built around those three. Before any design work, we profile your catalogue, customer records and historical orders in a sandbox and publish a migration matrix: every entity, where it lands, and what happens to the ones that do not map. You sign that matrix, so the data conversation happens in week two instead of launch week.
SEO survival is engineering, not luck. We crawl your live site, map every indexed URL to its new destination, and ship the 301 file as part of the build, not as a post launch patch. Metadata, canonicals and structured data are implemented on the new templates before migration rehearsal. After launch we watch indexation and search console daily for 60 days and fix drift as part of the contract. Our benchmark for recent replatforms is no net loss of organic sessions: verify the current sample in content/site.ts before quoting it.
On checkout, the rule is to extend, never fork. Checkout blocks and Shopify Functions run inside Shopify's upgrade path; rewritten checkout scripts run outside it and break on platform updates. Everything we ship in checkout is traceable to a metric: an upsell that pays, a validation rule that stops refund churn, a delivery option that converts. If a checkout change cannot be tied to a number, we will tell you not to build it.
The last week of a Plus project is not code, it is rehearsal. We run two full migration rehearsals against a copy of production, time each one, and write the go live runbook with named steps, owners and a rollback path. Launch day is deliberately boring: the runbook executes, the store opens, and your team has already been trained on the admin in two recorded sessions that stay yours.

What clients say about this work
The replatform paid for itself inside two quarters. Codioo scoped honestly, held the timeline, and the new store converts better in month one than our old one did at peak.
The integration just works. Orders land in NetSuite in minutes, stock comes back accurate, and our peak season ran without a single oversell.

Shopify Plus development FAQ
The questions clients ask before signing, answered plainly.
How much does Shopify Plus development cost?
A full Plus replatform with Codioo starts at $9,000 for a standard catalogue and runs $15,000+ when B2B, multiple markets or heavy historical data are in scope. Checkout extension sets start at $4,500. The audit converts your catalogue and requirements into a fixed quote within one business day, and the price only moves if the scope does.
How long does a Shopify Plus migration take?
Eight to twelve weeks is typical from kickoff to launch. A standard catalogue with one market lands at the low end. Multiple storefronts, B2B accounts, or migrating five years of order history push toward twelve. Two full migration rehearsals are built into that window, so launch week holds no surprises.
Will we lose SEO traffic when we move to Plus?
Not if the redirect work is treated as engineering. We crawl every indexed URL before build, ship the 301 map with the launch, keep metadata and structured data on the new templates, and monitor indexation for 60 days after cutover. Our replatform benchmark is zero net organic session loss, checked against your pre launch baseline.
Should we move to Plus or stay on Shopify Advanced?
Move when plan limits interrupt weekly work, when you need checkout changes, or when your GMV makes negotiated processing rates cheaper than the fee difference. Below roughly $1M annual revenue, Advanced is usually the better economics. The audit includes this comparison using your real numbers, and we have told prospects to stay on Advanced more than once.
Can you migrate us from Magento or WooCommerce?
Yes, both are common starting points. Catalogue, customers, reviews and content map through a migration matrix you approve in week one. Historical orders can come across or stay in an archive, your choice. The redirect map covers old URL structures completely, including the parameter heavy ones Magento is known for.
What is checkout extensibility on Plus?
Plus lets you modify checkout through supported building blocks: checkout blocks for layout and upsells, and Shopify Functions for discounts, delivery and validation logic. Because they run inside Shopify's upgrade path, platform updates do not break them. We build checkout changes only when tied to a metric, like upsell revenue or reduced refund churn.
Do you work with our existing designers?
Yes. If you have a brand system or in house designers, we build to their files and handle the implementation. If you do not, our design phase covers the templates that carry revenue first: home, collection, product, cart and checkout adjacent pages.
Who owns the Plus work after launch?
You do. Theme code, checkout extensions, Flow templates and documentation transfer to your repositories and staff accounts at launch. There is no lock in: care plans are monthly and cancellable with 30 days notice.
What support exists after a Plus launch?
Care plans from $2,500 a month cover uptime and speed monitoring, a monthly performance report against launch baseline, small fixes and a prioritised experiment backlog. Plus stores also get a quarterly platform review, since Shopify ships features that regularly replace paid apps.
How many Plus projects have you shipped?
Our working portfolio covers 140 stores across plans, with Plus replatforms as the core of our enterprise work. Every claim we make links to a named case study with baselines.
