For a multi-currency, multi-country B2B sales operation with localized catalogs and tax handling, I’d shortlist platforms based on how complex your selling model is (distributors vs. direct sales, negotiated pricing, ERP integration, regional catalogs, compliance needs).

Top recommendations

My practical recommendation by scenario

1. Global manufacturer/distributor (many SKUs, price lists, dealers)

Choose:

• Adobe Commerce or OroCommerce

Look for:

• Customer-specific catalogs
• Contract pricing
• Quote workflows
• Purchase orders and payment terms
• ERP integration
• Regional inventory visibility

2. B2B company expanding internationally quickly

Choose:

• BigCommerce B2B Edition or Shopify Plus

Good when you need:

• Faster rollout
• Local currencies
• Multiple storefronts/markets
• Lower operational overhead

BigCommerce’s multi-storefront model is particularly useful when regions need different catalogs, storefront experiences, or operations. IWD Agency

3. Highly customized global commerce stack

Choose:

• commercetools
• Spree Commerce
• Elastic Path

Good when you already have:

• A headless frontend
• ERP/PIM/CRM systems
• Internal engineering resources

Tax handling considerations

For international B2B, don’t evaluate only the ecommerce platform. You’ll usually need integrations for:

• VAT/GST/sales tax calculation
• Tax exemptions by customer type
• Import duties and landed cost
• Regional invoicing requirements
• Tax registrations

Common integrations include:

• Avalara
• Vertex
• TaxJar

Platforms such as Spree explicitly support tax integrations and regional tax configuration. Spree Commerce

My default shortlist

If I were selecting for a serious international B2B operation:

1. Adobe Commerce — most capable for complex global B2B
2. BigCommerce B2B Edition — best balance of capability and operational simplicity
3. OroCommerce — best if B2B workflows are the core requirement
4. Shopify Plus — best if you want B2B + consumer commerce together
5. SAP Commerce Cloud — best for large SAP-centric enterprises

A key decision point is whether you need one global catalog with localized overlays or separate regional catalogs with different products, pricing, and rules. The latter usually pushes you toward Adobe Commerce, BigCommerce Multi-Storefront, OroCommerce, or a composable platform. IWD Agency Alkali

Recommendation: Shopify Plus

For multi-country B2B sales with localized catalogs, currencies, and tax handling, I’d shortlist shopify.com first.

Why it fits:

• Multi-country: Shopify Markets lets you manage multiple markets from one store, with market-specific domains, languages, currencies, catalogs, pricing, and content. Shopify Shopify
• B2B catalogs: You can assign customer/company-specific catalogs, pricing, product availability, quantity rules, payment terms, and tax exemptions. Shopify App Store
• Multi-currency: Local-currency pricing and payments are built into its international commerce stack. Shopify Shopify
• Tax/duties: Shopify supports automated tax calculations and VAT handling; Managed Markets can additionally handle cross-border duties, taxes, customs, and merchant-of-record responsibilities where eligible. Shopify Shopify
• Single operating model: You can run B2B and D2C together rather than maintaining separate commerce platforms. Shopify's current B2B offering includes company profiles, custom catalogs, volume pricing, payment terms, and multi-currency support. Shopify App Store Shopify

How I'd compare the alternatives

BigCommerce is particularly worth evaluating if you have a headless architecture or unusually complex B2B requirements; Adobe Commerce is compelling when you need extensive customization and have the technical team to operate it. Shopify

Bottom line: I'd choose Shopify Plus + Markets for most companies selling B2B across several countries, especially if you want localized catalogs and currencies without building a large commerce engineering operation. If your tax requirement is specifically “the platform must become the tax/compliance system of record for every country we sell into,” I'd validate the exact countries and tax registrations before committing—Shopify's capabilities differ depending on whether you're using standard tax tooling or Managed Markets.

If you tell me your countries, currencies, approximate SKU count, ERP/CRM (e.g. SAP, NetSuite, Dynamics, Salesforce), and whether you sell D2C too, I can narrow this to a specific platform/architecture recommendation.

For a multi-currency, multi-country B2B sales operation with localized catalogs and tax handling, I’d shortlist platforms based on how complex your international selling model is (number of markets, ERP needs, pricing rules, and B2B workflows).

Shopify Alkali### My recommendation by scenario

1. Global B2B manufacturer or distributor (10+ countries, complex pricing)

• Pick: SAP Commerce Cloud or Adobe Commerce
• You likely need: - customer-specific price lists
• contract pricing
• regional product availability
• ERP synchronization
• tax/VAT/GST integrations
• approval workflows

2. Growing international B2B brand (5–20 markets, moderate complexity)

• Pick: Shopify Plus or BigCommerce
• These are usually faster to deploy while still supporting: - localized storefronts
• multiple currencies
• regional catalogs
• localized payment methods
• tax service integrations

IWD Agency Shopify3. Highly customized enterprise procurement flows

• Pick: commercetools
• Best if you need to combine: - custom pricing engines
• CPQ
• ERP-driven availability
• multiple front ends
• marketplaces or dealer portals

Capabilities I would require in your evaluation

• Catalog localization - Different SKUs by country
• Region-specific assortment
• Translation workflows
• Localized product attributes

• Currency management - Fixed price lists per currency (not only FX conversion)
• Currency rounding rules
• Customer/account currency preferences

• B2B pricing - Contract pricing
• Volume discounts
• Customer-specific catalogs
• Quote workflows

• Tax compliance - VAT/GST/sales tax calculation
• Tax exemption handling
• Reverse-charge support
• Integration with services such as Avalara or Vertex

• Operations - ERP integration (SAP, Oracle, NetSuite, Dynamics)
• Multi-warehouse inventory
• Local payment methods
• Regional fulfillment rules

For many companies, the practical shortlist ends up being:

1. SAP Commerce Cloud — if you are a global enterprise with SAP/ERP complexity
2. Adobe Commerce — if you need maximum B2B customization
3. Shopify Plus — if speed and operational simplicity matter most
4. BigCommerce — if you want enterprise B2B without as much complexity
5. commercetools — if you want a fully composable architecture

A useful next step would be narrowing this by your industry (manufacturing, wholesale, SaaS, distribution, etc.), number of countries, ERP, and whether pricing is public or negotiated per customer.

For multi-country B2B sales with different currencies, localized catalogs, and tax requirements, my top recommendation is Shopify Plus.

Why Shopify Plus fits

• Multi-country: Shopify Markets lets you create country/region-specific markets with localized domains, languages, currencies, products, pricing, and shipping. help.shopify.comhelp.shopify.com
• B2B catalogs: You can create customer/company-specific catalogs with different product availability and pricing; Plus supports unlimited catalogs and direct assignment to company locations. help.shopify.com
• Multi-currency: B2B customers can transact in local currencies, with either automatic conversion or fixed catalog prices. B2B multicurrency requires Shopify Payments. help.shopify.comexperienceleague.adobe.comcommercetools.com
• Tax handling: Taxes and duties can be calculated based on the customer's shipping address. For cross-border sales, Shopify's Managed Markets can additionally act as merchant of record and handle VAT, duties, and local taxes where eligible. help.shopify.comhelp.shopify.com
• B2B-specific functionality: Company accounts, multiple buyers/locations, payment terms, tax exemptions, custom pricing, and self-service purchasing are built in. apps.shopify.com

Shopify Plus B2B

How I'd rank the alternatives

Adobe Commerce is particularly strong if you need independent country websites and currencies: its multisite architecture can give each website its own base currency and pricing scope, while B2B Shared Catalogs support company-specific catalogs and pricing. experienceleague.adobe.com

commercetools is the better choice if you're building a highly customized headless stack: its catalog can define pricing by currency, country, customer group, and channel, while product content can be localized centrally. commercetools.com

Bottom line: choose Shopify Plus unless your organization has unusually complex pricing/catalog rules or already operates a substantial composable/ERP-centric architecture. For most companies expanding B2B across 5–30+ countries, it gives you the shortest path to localized buying experiences without building international commerce infrastructure yourself. help.shopify.comhelp.shopify.com

For your requirements, I’d shortlist Shopify Plus first, with BigCommerce and Adobe Commerce as alternatives.

My recommendation: Shopify Plus

It has a particularly good fit for multi-country B2B + localized catalogs + currencies + tax because the capabilities are increasingly native rather than requiring a large collection of extensions.

• B2B catalogs: customer/company-specific catalogs, pricing, quantity rules, payment terms, tax exemptions and permissions. apps.shopify.com
• Multi-currency & localization: Shopify Markets supports local currencies, payment methods, languages/content, domains and region-specific selling. www.shopify.com
• Tax/duties: Shopify supports automated tax calculations and VAT handling; Managed Markets can additionally handle duties, taxes and merchant-of-record responsibilities for eligible international sales. www.shopify.com
• B2B + DTC together: useful if you're selling wholesale and direct to consumers without wanting separate commerce stacks. www.shopify.com
• Scale: Plus currently starts around $2,300/month on a 3-year term, with custom pricing for more complex structures. www.shopify.com

Shopify Plus B2B

How I'd rank the alternatives

BigCommerce has strong multi-market capabilities, including localized storefronts, currencies, payment methods, shipping and tax integrations, plus tax-zone handling for cross-border transactions. docs.bigcommerce.com

Adobe Commerce is worth serious consideration if you need elaborate company hierarchies, shared catalogs, quoting, requisition lists, credit lines or highly customized B2B workflows. www.shopify.com

Bottom line: If your priority is “sell to businesses in many countries with different catalogs, currencies, languages and tax treatments without building a huge custom commerce stack,” I'd choose Shopify Plus. If your catalog/pricing/account hierarchy is exceptionally complex, I'd evaluate Adobe Commerce alongside it.

For your requirements, I’d shortlist Shopify Plus, with Adobe Commerce as the alternative if your B2B pricing/procurement logic is unusually complex.

My pick: Shopify Plus

Shopify is particularly strong if you want one commerce platform serving multiple countries, currencies, and B2B customer segments without building a large custom commerce stack.

Why it fits:

• Multi-country: Shopify Markets lets you define markets by country/region and tailor products, pricing, languages, domains, and storefront experiences per market. www.shopify.comwww.shopify.com
• Localized catalogs: You can expose different products and prices to different markets and B2B customers. B2B catalogs can be assigned to specific companies/locations. www.shopify.comapps.shopify.com
• Multi-currency: Local currencies and localized pricing are built into Markets; Shopify says its international tooling supports 130+ currencies. www.shopify.comwww.shopify.comapps.shopify.com
• B2B: Company accounts, buyer permissions, payment terms, customer-specific catalogs/pricing, volume discounts, and tax exemptions are supported. www.shopify.comapps.shopify.com
• Taxes/duties: Shopify can calculate/collect duties and taxes, while Managed Markets can act as merchant of record for eligible international transactions, handling foreign taxes, duties, and import fees. apps.shopify.com
• Operational simplicity: You can manage markets from a single store rather than maintaining separate country storefronts and synchronizing them. www.shopify.comwww.shopify.com

When I'd choose something else

Recent 2026 comparisons similarly position Shopify Plus around speed and lower operational overhead, while Adobe Commerce is stronger for sophisticated B2B workflows and customization. elogic.co

Bottom line: If your core requirement is “sell B2B across many countries with different catalogs, currencies, languages, prices, and tax treatment without creating a huge IT project,” I'd start with Shopify Plus + Shopify Markets, and evaluate Managed Markets for eligible cross-border sales.

If you tell me your number of countries, ERP (e.g. SAP/NetSuite), approximate SKU count, and whether you need customer-specific price lists/quotes, I can narrow this to a 2–3 platform shortlist.

For multi-country B2B sales with localized catalogs, currencies, and tax handling, my first choice would be Shopify Plus.

Why it fits particularly well:

• B2B-native: company accounts, buyer permissions, payment terms, tax exemptions, customer-specific catalogs, volume pricing, and quantity rules. apps.shopify.com
• Multi-country: Shopify Markets lets you tailor catalogs, prices, currencies, languages, domains, and content by market from one admin. Plus supports multiple B2B markets with distinct catalogs and currencies. www.shopify.com
• Localized catalogs: you can control which products are available in each market and layer B2B/customer-specific pricing on top. www.shopify.com
• Tax/duty handling: Shopify Managed Markets can act as merchant of record and handle international taxes, duties, and import fees; its adaptive pricing can incorporate taxes, duties, currency conversion, and fees into localized prices. www.shopify.com
• Reasonable operational complexity: compared with highly composable enterprise platforms, you can get a lot of this functionality without assembling as many separate commerce services.

When I'd choose something else

A key distinction: Shopify Managed Markets is strongest for cross-border international selling, whereas if you're operating separate legal entities in many countries with country-specific VAT/GST registration, invoicing, accounting, and ERP requirements, I'd treat the commerce platform as only one part of the architecture. You may still want an external tax engine and ERP/local accounting integrations.

My recommendation: start with Shopify Plus + Markets, and add a dedicated tax engine only if your tax complexity exceeds what Shopify's native/Managed Markets capabilities cover. Shopify Plus currently starts around $2,500/month on a 1-year term, with variable pricing possible for more complex structures. www.shopify.com

If you tell me number of countries, currencies, approximate SKU count, B2B pricing complexity, and ERP (e.g. SAP/NetSuite/Dynamics), I can narrow this to the best 2–3 architectures.

For a multi-currency, multi-country B2B sales operation with localized catalogs and tax handling, the best platform depends heavily on your complexity: number of countries, ERP needs, pricing rules, and whether you sell wholesale/distribution vs. direct online. These are the strongest candidates:

My shortlist by scenario

1. Global manufacturer/distributor (many SKUs, negotiated pricing, dealer networks)
→ Adobe Commerce or OroCommerce
You’ll likely need:

• customer-specific price lists
• contract pricing
• regional product availability
• ERP integration (SAP, Oracle, Microsoft Dynamics, etc.)
• approval workflows
• multiple tax regimes

2. B2B brand selling internationally but still fairly standardized
→ Shopify Plus + Markets
Good if you need:

• country-specific storefront experiences
• local currencies
• translated catalogs
• localized checkout
• tax/duty handling without a large IT team www.shopify.com

3. Distributor/wholesaler wanting SaaS without heavy engineering
→ BigCommerce B2B Edition
A strong middle ground between Shopify simplicity and enterprise functionality. www.gartner.com

4. Highly customized global commerce platform
→ commercetools
Best when commerce is part of a broader digital ecosystem and you have engineering resources.

Capabilities I would require before choosing

For your use case, make sure the platform supports:

• Multi-currency
  • fixed prices by currency (not only exchange-rate conversion)
  • currency rounding rules
  • customer-specific currencies

• Localized catalogs
  • country-level product availability
  • regional SKUs
  • translated attributes/specifications
  • different images/content per market

• B2B pricing
  • account-based pricing
  • contract pricing
  • volume discounts
  • negotiated quotes
  • customer groups

• Tax compliance
  • VAT/GST/sales tax rules
  • tax-exempt customers
  • reverse charge handling
  • integrations with services such as Avalara or Vertex

• Operations
  • regional warehouses
  • multi-country inventory
  • localized payment methods
  • ERP/CRM integration

Default recommendation

For most companies in this category:

• $5M–$100M international B2B revenue: Shopify Plus or BigCommerce
• $100M+ revenue, complex pricing/catalogs: Adobe Commerce or OroCommerce
• Global enterprise with custom digital architecture: commercetools

If you share your number of countries, annual B2B revenue, ERP (if any), SKU count, and whether customers need login-based pricing, I can narrow this to a specific recommendation.

For multi-country, multi-currency B2B sales with localized catalogs and tax handling, I’d recommend Shopify Plus.

Why it fits

• B2B catalogs: Shopify Plus supports unlimited B2B catalogs and lets you assign catalogs directly to companies/company locations—useful for customer- or region-specific assortments and pricing. help.shopify.com
• Multi-country localization: Shopify Markets lets you configure different currencies, languages, domains, product availability, pricing, duties and taxes by market. help.shopify.com
• Multi-currency B2B: Customers can transact in local currencies, while catalogs can also use fixed prices where you don't want FX conversion to determine the price. B2B multi-currency requires Shopify Payments. help.shopify.com
• B2B-specific commercial rules: Company locations can have their own catalogs, payment terms, tax exemptions, permissions, quantity rules and pricing. apps.shopify.com
• Tax: Shopify Tax handles automated tax calculation and B2B exemptions. For more complex international tax requirements, Shopify supports integrating Avalara, including product tax codes, exemptions and multi-entity tax configuration. help.shopify.comhelp.shopify.com

My architecture recommendation

Shopify Plus + Markets + Shopify B2B + Shopify Tax, with Avalara if your tax footprint is sufficiently complex.

That's particularly attractive if you're selling, for example:

US / Canada / EU / UK → different currencies → different product assortments → customer-specific wholesale pricing → VAT/sales-tax exemptions → localized storefronts

I would choose commercetools instead if you have a very complex enterprise architecture and need the commerce platform to be deeply composable/headless. Its catalog supports pricing by currency, country, customer group and channel, as well as localized product data. commercetools.com

Bottom line: Shopify Plus is the better default for getting sophisticated international B2B commerce running with less implementation complexity; commercetools is the stronger choice when architectural flexibility is more important than implementation speed.

For a multi-currency, multi-country B2B sales operation with localized catalogs and tax handling, I’d shortlist platforms based on how complex your international model is (number of countries, customer-specific pricing, ERP needs, tax requirements, etc.).

My recommendations by scenario

1. You sell globally but want speed and lower operational overhead
→ Shopify Plus
Good when you need:

• Multiple storefront experiences by region
• Local currencies
• Country-specific catalogs
• Localized content
• Tax/duty support
• A manageable admin experience

Shopify Markets supports localized B2B experiences, including market-specific currencies, pricing, domains, and catalogs. www.bigcommerce.comhelp.shopify.com

2. You have serious B2B requirements (distributors, wholesale buyers, account pricing)
→ BigCommerce or Adobe Commerce

Look for:

• Customer-specific price lists
• Contract pricing
• Buyer approval flows
• Multiple company accounts
• ERP synchronization
• Punchout/e-procurement support

BigCommerce provides multi-currency support, customer groups, catalog tools, and tax integrations such as Avalara connectivity. www.bigcommerce.com

3. You operate in many countries with complicated tax and compliance rules
→ Adobe Commerce or SAP Commerce Cloud

These are better if you need:

• Separate legal entities
• Complex VAT/GST rules
• Regional warehouses
• Multiple catalogs per country
• Deep ERP/CRM integration

Tax stack considerations

Regardless of platform, many global B2B companies pair commerce software with:

• Avalara or similar tax engines for VAT/GST/sales tax calculations
• ERP systems like SAP S/4HANA, Oracle NetSuite, or Microsoft Dynamics 365
• Payment providers supporting local methods (cards, bank transfers, wallets)

A practical shortlist

If I were selecting today:

• <$50M international B2B revenue: Shopify Plus or BigCommerce
• $50M–$500M with complex wholesale: BigCommerce, Adobe Commerce, or Spryker
• Enterprise with global subsidiaries: SAP Commerce Cloud or Adobe Commerce
• Need maximum flexibility and have developers: Spree Commerce or a headless architecture

If you share your number of countries, approximate SKU count, ERP (if any), sales model (direct B2B vs distributors), and whether customers need negotiated pricing, I can narrow this to 1–2 platforms.

For your requirements, I’d shortlist Shopify Plus, Adobe Commerce, and commercetools—but Shopify Plus would be my default recommendation unless you have unusually complex B2B pricing/procurement or need a highly customized architecture.

My pick: Shopify Plus

Shopify's current B2B + Markets combination maps unusually well to what you're describing. You can create markets by country/region or customer group and customize currency, catalogs, pricing, product availability, languages, domains, taxes and duties. help.shopify.com

For B2B specifically, Plus allows unlimited B2B market catalogs and catalogs assigned directly to individual companies/company locations. That makes it practical to have, for example:

• US distributors → USD + US assortment/pricing
• UK customers → GBP + UK catalog
• EU customers → EUR + EU catalog + VAT treatment
• Strategic accounts → customer-specific assortment and negotiated pricing

help.shopify.com

It also supports local-currency B2B selling, including either automatically converted prices or fixed catalog prices in a particular currency—useful when your international price lists aren't simply FX conversions. help.shopify.comhelp.shopify.com

For cross-border tax/duty complexity, Shopify's international tooling can handle tax and duty collection, while its Managed Markets offering goes further by acting as merchant of record for eligible international transactions. www.shopify.com

Shopify Plus B2B

When I'd choose Adobe Commerce instead

Choose Adobe Commerce if the business has genuinely complex regional commerce operations—multiple independent storefronts, extensive ERP integration, highly customized pricing/tax rules, or substantial differences between country catalogs. Adobe's multi-site architecture supports localized catalogs, languages, currencies, inventory locations and tax policies from a centralized platform. business.adobe.com

The tradeoff is implementation and operational complexity. Current 2026 comparisons generally position Adobe ahead for sophisticated B2B workflows, while Shopify Plus wins on speed and lower operational overhead. elogic.co

Adobe Commerce

Bottom line

I'd choose Shopify Plus if you're a mid-market/enterprise company wanting to launch and manage multiple countries without building a large commerce engineering organization.

I'd choose Adobe Commerce if tax, pricing, catalogs, ERP integration, and procurement rules are sufficiently complicated that you expect significant custom commerce logic.

I'd choose commercetools if you're deliberately building a composable commerce stack and already have the engineering organization to own it long-term.

One important caveat: “tax handling” can mean very different things—basic tax calculation versus VAT/GST registration, exemptions, tax-inclusive pricing, invoicing, fiscalization, and multi-entity compliance. If you tell me your countries, approximate number of SKUs, ERP (e.g. SAP/NetSuite/Dynamics), and whether you sell B2B only or B2B + DTC, I can narrow this to a specific platform/architecture.

For multi-currency, multi-country B2B sales with localized catalogs and tax handling, I’d shortlist Shopify Plus first, with Adobe Commerce as the alternative if your B2B procurement logic is highly complex.

My pick: Shopify Plus

It’s a particularly good fit if you want one commerce platform for international B2B + potentially DTC, without building a heavily customized commerce stack.

• Multi-country: Shopify Markets lets you define markets by country/region and tailor currencies, pricing, product availability, domains, and languages. www.shopify.com
• Multi-currency: Shopify supports local-currency selling across 130+ currencies, with Shopify Payments. www.shopify.com
• Localized catalogs: Markets can control which products are available in each market; B2B also supports customer-specific catalogs and pricing. Shopify expanded native B2B capabilities to all plans in 2026. www.shopify.com
• Taxes/duties: Shopify can calculate sales taxes, while Managed Markets can act as merchant of record and handle international duties, taxes, and import fees. www.shopify.comapps.shopify.com
• Operational simplicity: Compared with a composable platform, you get considerably more out of the box and generally have less infrastructure to maintain.

When I'd choose Adobe Commerce instead

Adobe Commerce is the stronger choice if you have complex B2B procurement—for example, sophisticated account hierarchies, negotiated quotes, approval workflows, requisition lists, credit limits, or highly customized ERP processes. A current 2026 comparison finds Adobe has the deepest native B2B feature set, whereas Shopify emphasizes speed and lower operational overhead. elogic.co

What about commercetools?

commercetools is worth considering if you're deliberately building a composable/headless architecture. Its catalog can define pricing by currency, country, customer group, and channel, and localize product information and assortments. commercetools.com But you'll typically need substantially more engineering work for the surrounding B2B workflows.

Bottom line:
Shopify Plus → best overall balance of global B2B, localized catalogs, currencies, tax/duty handling, and implementation effort.
Adobe Commerce → better for unusually complex B2B pricing/procurement and deep customization.
commercetools → best when composable architecture and engineering flexibility are strategic priorities.

If you tell me your number of countries, currencies, ERP (e.g. SAP/NetSuite), and whether you need customer-specific pricing/quotes, I can narrow this to a specific recommendation and architecture.

For a multi-currency, multi-country B2B sales operation with localized catalogs and tax handling, the best platform depends on how complex your sales model is (number of countries, ERP needs, pricing rules, buyer workflows, etc.). These are the strongest candidates:

My shortlist by scenario

1. You sell internationally but want to launch quickly
→ Shopify Plus
Best balance of global capability and operational simplicity. Good for:

• Multiple countries/regions
• Local currencies
• Translated storefronts
• B2B customer accounts
• Regional catalogs and pricing rules

help.shopify.com

2. You have complex B2B pricing
Examples:

• Customer-specific price lists
• Distributor pricing
• Volume discounts
• Buyer approval workflows
• Thousands of SKUs

→ BigCommerce or Adobe Commerce
BigCommerce is easier to operate; Adobe Commerce is more customizable. www.bigcommerce.com

3. You need a global commerce engine integrated with ERP
Examples:

• SAP
• Microsoft Dynamics
• Oracle
• Custom order management

→ Adobe Commerce, Salesforce Commerce Cloud, or Spree/Solidus

4. You need country-specific storefront logic
Examples:

• Germany sees different products than the US
• Different VAT rules
• Different assortments
• Different payment methods

→ Spree Commerce, Adobe Commerce, or Shopify Plus
Spree is particularly strong if your team can build and maintain custom workflows. spreecommerce.org

Features I would require in your evaluation checklist

• ✅ Customer-specific B2B price lists
• ✅ Multiple currencies with fixed regional pricing (not only FX conversion)
• ✅ Country-specific catalogs and product availability
• ✅ VAT/GST/sales tax support
• ✅ Tax engine integrations (Avalara, Vertex, etc.)
• ✅ Multiple legal entities/storefronts if needed
• ✅ Local payment methods
• ✅ ERP/PIM/CRM integrations
• ✅ Quote requests and negotiated pricing
• ✅ Purchase orders and approval workflows
• ✅ Regional shipping rules and landed-cost calculation

A common enterprise architecture is:
ERP (SAP/Dynamics/Oracle) + PIM + Commerce platform + tax engine + payment providers rather than expecting the commerce platform alone to manage every global commerce process.

If you share your approximate scale (number of countries, SKUs, annual B2B revenue, ERP, and whether buyers need negotiated pricing), I can narrow this to 2–3 platforms.

For your requirements, I’d shortlist Adobe Commerce and BigCommerce, with Adobe Commerce as my first choice if the B2B side is genuinely complex.

My recommendation: Adobe Commerce

Adobe’s Adobe Commerce is particularly strong when you need country-specific catalogs, customer-specific B2B pricing, currencies, and tax rules in one architecture.

• Localized catalogs: Multiple websites/stores/store views can have different products, categories, languages, domains, and currencies. experienceleague.adobe.com
• Multi-currency: Base currencies can be configured at the website level, with support for currencies from 200+ countries. experienceleague.adobe.com
• B2B catalogs/pricing: Shared catalogs let you give different companies or customer groups different product selections and prices, including across multiple websites. experienceleague.adobe.com
• Tax: Native tax zones, rates, rules, and customer/product tax classes are built into the platform. experienceleague.adobe.com
• Country-specific pricing: Product prices can be scoped at the website level, which is useful when regional pricing isn't simply an FX conversion. experienceleague.adobe.com

Trade-off: It's considerably more complex to implement and operate than a SaaS platform. I'd favor it if you have an enterprise commerce/IT team and your catalog, pricing, ERP, tax, or B2B workflows are complicated.

When I'd choose BigCommerce instead

BigCommerce is the better choice if you want SaaS simplicity and faster implementation while still getting substantial international B2B capabilities.

Its B2B offering supports buyer-specific experiences by location, language, currency and customer segment, while its multi-storefront architecture can localize products, categories, price lists, currencies, checkout and promotions by market. www.bigcommerce.com It also supports tax zones and cross-border tax-inclusive/exclusive price presentation. docs.bigcommerce.com

Quick decision

Bottom line: If “multi-country B2B” means subsidiaries, customer-specific assortments, negotiated pricing, different tax treatments, multiple currencies and potentially different checkout/payment rules, I’d start with Adobe Commerce. If those requirements are important but you want a more managed SaaS operation, BigCommerce is probably the better balance.

Adobe Commerce
BigCommerce B2B Commerce

A third option worth evaluating for a very sophisticated/headless organization is commercetools: its catalog supports pricing by currency, country, customer group and channel, plus localized product data and B2B-specific pricing/tax configuration. commercetools.com
