Shopify Plus for custom, B2B & global commerce

We design, build and migrate Shopify Plus stores, and we build the apps other merchants install. Plus pays off when you need custom checkout logic, advanced B2B, multiple stores or real scale. Those are the projects we do best.

Among the brands we build for on Shopify Plus

What Shopify Plus actually unlocks in 2026

The features only Plus offers. That is exactly where our app engineering helps most.

Custom Shopify Functions

Build your own discount, shipping, payment and cart logic instead of stacking ready-made apps from the App Store.

Pre-purchase checkout customization

Checkout UI extensions on the information, shipping and payment steps, plus full checkout branding.

Advanced B2B

Unlimited B2B catalogs with per-company pricing, deposits and partial payments. Lower plans get three catalogs.

Multi-store & expansion

A main store plus up to 9 expansion stores, managed centrally with Organization admin.

Scale & throughput

Roughly 10× higher API rate limits, higher checkout capacity for peak events, and unlimited staff accounts.

Economics & support

Lowest payment rates, only a 0.2% fee on other gateways, POS Pro included, Launchpad and priority 24/7 support.

From one market to global Shopify Plus

We took a Czech brand selling in one market to a global Shopify Plus store. We added multiple currencies, an integration with their own ERP and B2B sales in the same store.

When Plus pays for itself

The more you sell, the more you save on fees. Above a certain revenue, Plus saves more than it costs. Based on Shopify's Czech price list*.

Lower card rates

With Shopify Payments you pay 1.3% on Plus instead of 1.6% on Advanced. The fixed 6.50 CZK per transaction stays on every plan.

Cheaper other gateways

The fee on other gateways drops from 0.6% on Advanced to 0.2%. With Shopify Payments switched on it can be zero, even if you hide them at checkout. With them on, cash on delivery, bank transfer and PayPal carry no fee on any plan.

A rule of thumb

On fees alone, Plus pays for itself from roughly ten million CZK a month in card payments. Around five million, it's enough for Plus features to lift revenue by about 2% (at a margin of around 30%), for example with offers right in the checkout.

Facederma, cosmetics. Case study: two stores moved from WooCommerce to Shopify Plus, with B2B for salons

Proof on Plus Facederma

From WooCommerce to Shopify Plus, for shoppers and salons

We moved two WooCommerce stores, one for Slovakia and one for Czechia, to two Shopify Plus stores, each with its own currency and payments. On Plus we then built B2B sales for salons in the same store: their own catalog and company price lists.

Don't need Plus yet?

Most stores grow on the lower plans. We build stores without Plus too, and when Plus starts to make sense, you move up without a new project.

Why Appfleece for Shopify Plus

We work with Shopify Plus merchants every day. We meet them through the apps we publish and as the long-term partner who runs their development.

Plus merchants, every day

We build the apps other merchants install. Globe, Payflow, Charm, Heureka and Address IQ run on hundreds of stores, Plus brands among them, so checkout, Functions and APIs are everyday work for us.

Your long-term dev team

We don't stop at one-off projects. For growing brands we are the ongoing development partner: custom features, integrations and day-to-day engineering.

Migrations & rescues, proven

We have delivered complete Plus migrations, grown stores onto Plus with their owners and taken over stalled builds from other agencies. Brands include Posedla, Life is Porno, Verra and Facederma.

Verra, vitamins and supplements. Case study: Shopify Plus upgrade with a custom warehouse app and international expansion

Step by step to Plus Verra

Premium vitamins for women and a kids' line with a face of its own

We started in 2023 with a custom theme on a lower plan. Once the store had grown, it moved to Shopify Plus without a new project, then came more markets, discounts through Shopify Functions and the Synlab lab integration.

Shopify Plus, answered honestly

What does Shopify Plus actually cost?

In Czechia Plus starts at €2,100 a month, with a variable fee for very large merchants. We work out what you save on fees and what Plus actually unlocks for you.

What does Plus add over the Advanced plan?

Mainly: custom Shopify Functions, pre-purchase checkout customization, advanced B2B, multiple stores, ~10× API limits, unlimited staff, and priority 24/7 support. Markets, basic B2B and Flow are on lower plans now, so they're not reasons to upgrade.

Do I need Plus to sell internationally or do B2B?

No. Shopify Markets and B2B are available on standard plans too, B2B with up to three catalogs. Plus pays off for extensive B2B with unlimited catalogs and deeper customization. For high-volume merchants the lower transaction fees often cover the cost of Plus on their own.

Is migrating to Plus risky for SEO or uptime?

Not when it's done right. We run a phased migration with a full 301 redirect map, SEO preservation and data-integrity checks, so your store stays online. Short ranking swings after a move are normal, Google says. The redirects are what keep rankings in the long run.

How long does a Plus build or migration take?

It depends on scope, but a typical Plus migration runs ~8–16 weeks and a focused custom build can be quicker. After a short discovery we give you a concrete timeline, not a vague range.

Can you take over a Plus project another agency started?

Yes, we regularly take over stalled or half-built Plus projects. We audit what exists, stabilise it and carry on from there. That said, we prefer to work with merchants from the very start of the build.

Do you keep working with us after launch?

We take on few projects precisely so we can stay with them. After launch the same collaboration continues: new features, integrations, new markets and whatever Shopify is changing.

Which apps and integrations do you work with?

We offer our own Shopify apps at discounted partner pricing and build custom apps and integrations. We connect ERP, PIM and WMS systems as well as tools like Klaviyo, Recharge and Gorgias. When off-the-shelf won't do, we write custom Shopify Functions.
