B2B Ecommerce Platform Selection Framework 2026: APAC Buyer Guide

Quick Answer: Select a B2B platform by documenting your real pricing and approval logic first, weighting seven criteria before demos, scoring each vendor 1–5, then validating the top two with a paid proof-of-concept on your actual price list and ERP sandbox.

A Taiwan-headquartered industrial components manufacturer came to us with a familiar shape of problem. Three hundred dealers across Taiwan, Vietnam, Malaysia and Australia. Price lists maintained in Excel, emailed monthly. Orders arriving by fax, WhatsApp, and a sales rep's personal inbox. Their ERP held the authoritative inventory, but no dealer could see it. Their CFO wanted the order-to-cash cycle shortened. Their sales director wanted reps to stop keying in orders. Neither of them wanted to talk about platforms — they wanted to talk about the 2026 budget.

That is the actual starting point for most replatforming decisions, and it is why a B2B ecommerce platform selection framework 2026 has to begin with commercial workflows rather than feature checklists. The vendor comparison grids circulating online — ten platforms, forty rows, every box ticked — are close to useless for an APAC buyer, because they ignore the two variables that decide the outcome: how your pricing logic actually works, and whether the platform's integration layer can talk to the systems you already run in five jurisdictions.

This guide is built for brands weighing Shopify Plus, Adobe Commerce and SHOPLINE for B2B, with a scoring model you can run in a workshop and defend to a board.

Why 2026 Changes the Calculation

Three shifts have landed since the last serious wave of B2B replatforming.

First, buyer behaviour. McKinsey's B2B Pulse research has consistently found that B2B buyers now move across roughly ten channels during a purchase journey, and that e-commerce has become one of the most effective revenue channels alongside in-person and remote selling — not a secondary one. Gartner's B2B sales research has made the same point from the seller's side: buyers spend a minority of their buying-cycle time with any sales representative, which means your self-service surface is doing more selling than your reps are.

Second, native B2B capability has arrived in platforms that previously required custom builds. Shopify shipped B2B on Shopify as a native capability for Plus merchants — company profiles, multiple buyer contacts, price lists, payment terms, and B2B-specific checkout — removing the need for the third-party wholesale apps that defined the 2019–2022 era. Adobe, meanwhile, has repositioned Adobe Commerce around a cloud-native service model, which changes the upgrade and hosting economics for anyone still running Magento Open Source or a self-managed 2.4.x estate.

Third, the regional layer got heavier. GST and VAT digital reporting obligations, e-invoicing mandates (Malaysia's phased MyInvois rollout being the most immediate for APAC manufacturers), and multi-currency settlement across HKD, SGD, TWD, AUD and VND are now implementation line items, not footnotes.

So the honest framing: you are not choosing a storefront. You are choosing which system owns your pricing logic, your customer hierarchy, and your order orchestration for the next five to seven years.

The Seven Criteria That Actually Separate Platforms

Feature parity is largely a myth at the headline level and entirely real at the detail level. These are the seven dimensions where the differences bite. Suggested weightings are in brackets — adjust them, but adjust them before you see any demos, not after.

1. Pricing and catalogue logic (weight: 20%)

This is where most B2B implementations fail quietly. Ask every vendor to model your worst pricing case live, not in a slide. Specifically:

• Customer-specific price lists, and how many a single buyer can be attached to
• Volume/tier breaks on a per-SKU and per-category basis
• Contract pricing with effective-from and expiry dates
• Currency-specific lists (not FX-converted at render time)
• Whether price overrides can be pushed from ERP via API or must be maintained in-platform
• Catalogue segmentation — can Dealer A see 400 SKUs and Dealer B see 1,200, with different MOQs?

Adobe Commerce's B2B module handles shared catalogues and company-specific pricing as a first-class concept. Shopify handles this through B2B catalogs and price lists attached to company locations, which covers most tier and contract scenarios but has caps you need to confirm against your SKU count. SHOPLINE's B2B capability is strongest in the Greater China wholesale and distributor pattern — where it was built — and thinner on deeply nested shared-catalogue hierarchies.

2. Account and approval hierarchy (weight: 15%)

A company is not a customer. You need: parent company, child locations, buyer roles, spending limits, and multi-step approval chains. Adobe Commerce B2B ships company accounts with configurable roles and purchase-order approval rules out of the box. Shopify's company/location model is simpler and faster to configure, with ordering-only and ordering-and-payment permissions — adequate for dealer networks, lighter for procurement-heavy enterprise buyers who need three-level approval thresholds.

3. Integration maturity (weight: 20%)

Rate this on evidence, not on "we have an API". Ask for:

• Named, maintained connectors to your ERP (SAP S/4HANA, Business Central, NetSuite, Oracle, or a regional system like Yonyou or Kingdee)
• Webhook coverage and event granularity
• API rate limits under bulk sync — a 50,000-SKU nightly price refresh is a real load pattern
• Bulk/async operations rather than record-by-record writes

A practical test on Shopify is whether your pricing model fits the B2B GraphQL surface cleanly:

1mutation CreateCompanyLocation($companyId: ID!) {
2  companyLocationCreate(
3    companyId: $companyId
4    input: {
5      name: "Dealer – Ho Chi Minh"
6      billingAddress: { countryCode: VN, city: "Ho Chi Minh City" }
7      buyerExperienceConfiguration: {
8        checkoutToDraft: false
9        paymentTermsTemplateId: "gid://shopify/PaymentTermsTemplate/4"
10      }
11    }
12  ) {
13    companyLocation { id name }
14    userErrors { field message }
15  }
16}

On Adobe Commerce, the equivalent reality check is whether your team can operate the CLI and deployment lifecycle:

1bin/magento module:enable Magento_B2b
2bin/magento setup:upgrade
3bin/magento indexer:reindex catalog_product_price
4bin/magento config:set btob/website_configuration/company_active 1

If nobody on your side is comfortable with that second block, your total cost of ownership just moved — you are buying an agency retainer alongside the licence.

4. Regional and compliance fit (weight: 10%)

Payment methods are the fastest disqualifier. For APAC B2B you will typically need bank transfer with remittance matching, FPS or PayNow in Hong Kong and Singapore, local card acquiring in Australia and Taiwan, and increasingly e-invoicing hooks for Malaysia and Vietnam. Also check: Traditional Chinese and Simplified Chinese storefront handling as distinct locales, address formats that don't assume a Western street grid, and tax engine support for GST/VAT registration thresholds per market.

5. Total cost of ownership over 5 years (weight: 15%)

Licence is the smallest number. See the pricing section below.

6. Operational self-sufficiency (weight: 10%)

How much can your merchandising or sales-ops team change without a developer? Adobe Commerce gives enormous control and demands commensurate skill. Shopify trades ceiling for speed. SHOPLINE is the most "operate it yourself" of the three in its home markets.

7. Extensibility and exit cost (weight: 10%)

Headless readiness, data export completeness, and whether your customer/pricing data is portable. Ask the uncomfortable question in the sales cycle: what does leaving look like? Vendors who answer it well are usually confident in their retention for the right reasons.

Pricing: Real Numbers, With Caveats

Published list pricing in this category is partial and negotiated outcomes vary, so treat these as planning ranges and verify in writing. Figures are USD unless noted.

Shopify Plus

Shopify's published Plus pricing starts at $2,300 per month on a three-year term, or $2,500 per month month-to-month, per Shopify's own plan pages. Above a GMV threshold, pricing moves to a variable model based on a percentage of sales, and Shopify documents a monthly platform fee cap for large merchants. Payment processing is separate and market-specific. B2B functionality is included with Plus rather than sold as a module — a material difference from the previous app-dependent model.

Budget additions: apps (typically $300–1,500/month for a B2B estate covering ERP sync, tax, and approval extensions), and implementation. A mid-complexity APAC B2B build with one ERP integration and two markets commonly lands in the $60,000–200,000 range with a competent regional partner; multi-market dealer portals with custom pricing logic run higher.

Adobe Commerce

Adobe does not publish list pricing. Market-reported annual licence bands have for several years clustered around $22,000 to $125,000+ per year, tiered by GMV and order volume, with Adobe Commerce Cloud adding hosting and services on top. The B2B module is bundled with Adobe Commerce (not Magento Open Source). Adobe's more recent Commerce as a Cloud Service positioning shifts the operational burden, but you should ask directly how it prices relative to the legacy Cloud SKU and what the migration path looks like from 2.4.x.

Implementation is the dominant cost. Enterprise Adobe Commerce B2B builds in APAC realistically start around $150,000 and frequently exceed $400,000 when ERP, PIM, and multi-site rollouts are in scope. Add an ongoing maintenance retainer — security patches and upgrade cycles are not optional on this stack.

SHOPLINE

SHOPLINE publishes tiered plans in its Greater China and Southeast Asian markets at the SME end — typically in the low hundreds of USD per month equivalent, billed in HKD, TWD or SGD — with enterprise and B2B wholesale capability quoted on request. The commercial logic differs from the other two: lower entry cost, strong regional payment and logistics coverage, and a significantly shorter implementation path for a Greater China distributor model. The trade-off is a smaller third-party extension market and less depth for complex global procurement workflows.

The number people forget

Across engagements, the line item most often under-budgeted is data migration and pricing-model reconciliation — cleaning up the price lists that have drifted across spreadsheets for a decade. It is unglamorous, it cannot be parallelised easily, and it has sunk more go-live dates than any technical constraint. Budget for it as a named workstream, not a task.

A Scoring Framework You Can Actually Run

Forget the PDF checklist. Run this as a two-hour workshop with sales, finance, IT and operations in the same room.

Step 1: Fix the weights before demos

Use the seven criteria above. Reallocate the percentages to reflect your business — a dealer network weights pricing logic and ERP integration heavily; a spare-parts aftermarket business weights catalogue search and reorder behaviour; a regional distributor weights payments and logistics. Lock the weights. Write them down. This single discipline prevents the most common failure mode, which is a vendor demo quietly rewriting your priorities.

Step 2: Score each platform 1–5 per criterion

• 5 — Native capability, demonstrated live on your data
• 4 — Native, demonstrated on vendor sample data
• 3 — Achievable via supported extension or configuration
• 2 — Requires custom development
• 1 — Requires custom development against the platform's grain

The distinction between 3 and 2 is where honesty matters. A vendor saying "that's possible" means 2 unless they can name the extension.

Step 3: Multiply, total, and inspect the shape

A worked example for the Taiwan manufacturer pattern described at the top — 300 dealers, four markets, SAP Business One, complex tier pricing:

• Pricing logic (20%): Adobe 5, Shopify 4, SHOPLINE 3
• Account hierarchy (15%): Adobe 5, Shopify 4, SHOPLINE 3
• Integration maturity (20%): Adobe 4, Shopify 4, SHOPLINE 3
• Regional fit (10%): Adobe 3, Shopify 4, SHOPLINE 5
• 5-year TCO (15%): Adobe 2, Shopify 4, SHOPLINE 5
• Operational self-sufficiency (10%): Adobe 2, Shopify 5, SHOPLINE 4
• Extensibility / exit (10%): Adobe 4, Shopify 4, SHOPLINE 3

Weighted totals: Adobe Commerce 3.80, Shopify Plus 4.10, SHOPLINE 3.60. Close enough that the scores are not the decision — they are the structure of the decision. What the shape tells you is that Adobe wins on depth and loses on cost and self-sufficiency; Shopify is the balanced choice when your pricing logic fits its model; SHOPLINE wins decisively if your centre of gravity is Greater China and your approval workflows are simple.

Step 4: Run a proof-of-concept on the two highest scorers

Not a demo. A two-to-three-week paid POC with your real price list, your real SKU taxonomy, and one live ERP endpoint in a sandbox. Every serious platform decision we have seen go wrong skipped this step. Every one that went well did not.

Step 5: Re-score after the POC

Scores move. That is the point.

What the Practitioner Threads Get Right

If you search this topic you will find Reddit and Slack threads full of implementers arguing about the same three points. They are mostly right:

"The platform is 30% of the project." Correct. ERP integration, data cleanup, and change management with your sales team are the other 70%. Reps who have owned pricing discretion for fifteen years do not hand it to a portal without a plan.

"Adobe Commerce is not expensive because of the licence." Also correct. It is expensive because it requires a standing engineering capability. If you have that capability — or a long-term regional partner — the ceiling is genuinely higher. If you do not, the TCO gap versus Shopify Plus widens every year.

"Shopify B2B hits walls at the edges." Fair. The native model is opinionated. Where it fits, implementation is fast and cheap relative to alternatives. Where your pricing requires per-customer per-SKU matrices with date-bounded contracts and nested approvals, you will be building, and the build fights the grain.

What the threads tend to miss is the APAC-specific layer: settlement currency, local acquiring, Traditional vs Simplified Chinese as separate commercial contexts, and the operational reality that your warehouse team in Shenzhen and your finance team in Singapore need different things from the same order record.

Where This Is Heading

Two developments will reshape this evaluation within eighteen months.

The first is agentic commerce. Both Shopify and Adobe have shipped AI capability aimed at merchandising and support, but the more consequential version for B2B is machine-readable catalogue and ordering — buyers' procurement agents querying your catalogue and placing orders through APIs rather than browsing a storefront. If that becomes material in your category, your API surface stops being plumbing and becomes the channel. Score it now even if you cannot use it yet.

The second is the continued unbundling of the monolith. Composable architecture arguments have calmed from their 2022 peak — most APAC mid-market B2B brands do not have the engineering depth to run a composable estate well — but selective composability is now normal. Keeping the storefront on Shopify Plus while running pricing in a dedicated service, or PIM outside the platform entirely, is a defensible middle path. Ask vendors how gracefully they lose ownership of a domain.

One honest constraint worth stating: no platform on this list will fix a pricing model your own finance team cannot articulate. We have watched replatforming projects stall for weeks not on technology but on the discovery that three regional offices applied the same discount term three different ways. The system forces the clarity. That is often its highest-value contribution, and nobody puts it in the business case.

How to Evaluate: Your Next 30 Days

A B2B ecommerce platform selection framework 2026 is only useful if it produces a decision. Here is the sequence that does.

Days 1–5 — Document the commercial model. Write down every pricing rule, discount term, MOQ, and approval threshold that exists in practice. Not the policy — the practice. This document is your RFP.

Days 6–10 — Fix weights and build the scorecard. Seven criteria, agreed percentages, signed off by sales, finance and IT. No vendor in the room.

Days 11–20 — Run scripted demos. Send the commercial model document in advance. Require each vendor to demonstrate your three hardest pricing scenarios and one ERP sync. Score immediately after each session, before the next one.

Days 21–30 — Scope the POC. Two platforms, one real price list, one sandbox ERP connection, a defined pass/fail. Then re-score.

If your weighted leader survives the POC, you have a defensible decision and a realistic budget. If it does not, you have saved yourself a seven-figure five-year commitment for the cost of three weeks — which is the best return available anywhere in this process.
