Shopify B2B Site Cost — Plus + Wholesale Apps

A Shopify B2B site costs $8,000-$60,000 to build in 2026, with the typical mid-market B2B brand landing at $24,000 in my 600-project sample. Monthly ongoing: $500-$3,500 (Shopify Plus $2,300+, apps, payment processing, ERP integration). B2B builds are 3-5x more expensive than B2C Shopify because of customer-specific pricing, NET 30 terms, multi-location accounts, approval workflows, and frequent ERP integration.

Real bands:

A B2B brand I scoped in 2025 (Italian leather goods, wholesale to 280 retailers) needed customer-specific pricing, NET 30 terms, region-specific shipping, multi-language (EN/IT/DE), and SAP integration for inventory + order sync. Total build: $48,000 over 4 months on Shopify Plus. They were comparing to BigCommerce Enterprise ($65,000 quote) and Adobe Commerce ($120,000 quote). Shopify Plus B2B won on speed and cost.

Native Shopify B2B (Plus only)
Since 2023, Shopify Plus includes native B2B features:

• - Company accounts (organize buyers by company)
• Per-company catalogs and pricing
• Multi-location accounts
• Quantity rules and volume discounts
• Customer-specific shipping
• Draft orders + manual order workflow
• NET 30 / 60 / 90 payment terms (via Shopify Capital or external)
• B2B and B2C in same store (single inventory)
• Customer accounts (new login model)

Wholesale apps (Standard Shopify):

• - Wholesale Helper Suite (free + paid plans)
• Wholesale Pricing Discount ($24.99/mo)
• B2B Wholesale Solution ($49.99-$249/mo)
• Bold Custom Pricing ($39.99-$179.99/mo)
• B2B Login & Lock Down ($14-$29/mo)

Cost comparison for 200-account B2B brand:

• - Native Shopify B2B on Plus: $2,300/mo (Plus base, B2B included)
• Standard Shopify + apps: $39-$399/mo Shopify + $79-$300/mo wholesale apps = $118-$699/mo
• Migration cost from apps to native: $5,000-$20,000

When to use apps (Standard Shopify):

• - Under 30 wholesale accounts
• B2B revenue under $200K/year
• Mostly B2C with B2B as side channel
• Cost-sensitive (revenue not yet justifying Plus)

When to use Plus native B2B:

• - 50+ wholesale accounts
• B2B revenue over $500K/year
• Need multi-location accounts
• Need draft order + manual workflow
• Need NET 30 / 60 / 90 terms
• B2B is primary channel

Bottom line: Standard Shopify + wholesale apps is a "hack" that works under 30 accounts. Above that, Plus native B2B is meaningfully better and the cost difference is justified.

For Shopify-platform context see shopify store cost 2026.

1. Customer-specific pricing (+$2,000-$8,000)
Different tiers (Bronze, Silver, Gold), different products available per tier, per-customer overrides. Plus native B2B handles this; apps require workflow setup.

2. Account approval workflow (+$1,500-$5,000)
New B2B accounts apply with tax ID, resale certificate, business details. Pending approval flow, admin review, account-created notifications.

3. NET 30 / 60 / 90 payment terms (+$2,000-$10,000)
"Pay in 30 days" rather than at checkout. Shopify Plus B2B has native support via deferred payment. External: Slope, Resolve Pay, Stripe Capital. Custom: $3,000-$8,000.

4. Volume + quantity rules (+$800-$3,000)
"Order 50+ get 5% off, 100+ get 10% off." Native in Plus B2B. Apps handle but with limits.

5. Multi-location accounts (+$1,500-$5,000)
A retailer with 12 store locations needs one account, multiple ship-to addresses, location-aware invoicing. Plus native handles.

6. Draft orders / manual order workflow (+$1,500-$4,000)
Sales rep creates draft order, sends to customer, customer approves, payment processes. Common in B2B with reps.

7. Customer-specific catalogs (+$1,500-$5,000)
Customer A sees products 1-50; Customer B sees products 30-100. Native in Plus B2B; apps handle differently.

8. ERP integration (+$3,000-$25,000)
NetSuite, SAP, Microsoft Dynamics, Sage, QuickBooks Enterprise. The biggest cost driver in B2B builds — 20-40% of total project cost.

9. EDI integration (+$2,000-$15,000)
For retail buyers (Target, Walmart, Costco): Electronic Data Interchange via SPS Commerce, TrueCommerce, etc. ~$200-$1,000/mo + $2,000-$15,000 setup.

10. Sales rep tools (+$1,000-$5,000)
Sales reps need: customer-specific pricing visibility, order creation, payment links, follow-up reminders. ShopBy or custom rep portal.

11. Multi-currency / multi-region (+$2,000-$8,000)
Display prices in customer-local currency, charge in their currency. Native in Plus.

The cost driver at this tier is ERP integration. NetSuite or SAP integration is $8,000-$25,000 depending on data sync complexity (one-way orders to ERP vs full bidirectional inventory sync). EDI for retail accounts (Target, Walmart) adds $2,000-$15,000 + ongoing fees.

A mid-market B2B I scoped in 2025 (industrial supplies, 220 accounts) built at $36,000 over 14 weeks. They had been on a custom .NET application that cost $4,000/mo to maintain. Annual savings: $48,000 in maintenance plus $35K/year of incremental revenue from improved B2B UX. Payback: roughly 6 months.

For ERP-integration cost see api integration cost 2026.

Enterprise B2B and hybrid B2B/B2C builds add significant complexity:

Multi-store architecture ($10,000-$30,000)
Separate B2C and B2B storefronts (or B2C + multi-region B2B) sharing inventory. Shopify Plus supports up to 9 expansion stores. Architecture + setup: $10,000-$30,000.

Multi-region (US + EU + APAC) ($8,000-$25,000)
Region-specific catalogs, pricing, tax (VAT, GST, sales tax), shipping zones, languages, currencies, payment methods. Each region adds $3,000-$10,000.

EDI for retail buyers ($5,000-$20,000)
Walmart, Target, Costco, Kroger — all require EDI 850 (PO), 855 (PO Ack), 856 (ASN), 810 (Invoice). SPS Commerce or TrueCommerce platform + integration. Setup: $5,000-$15,000 + $400-$1,500/mo.

Custom sales rep portal ($5,000-$20,000)
Reps see their assigned customers, create orders, view commissions, set follow-ups. Often built as headless dashboard against Shopify B2B API.

Procurement integration ($5,000-$25,000)
Punch-out catalogs (Coupa, SAP Ariba, Oracle Procurement) for enterprise customers. cXML, OCI, or OAGIS integration.

B2B-specific apps ($200-$2,000/mo)
Sufio (B2B invoicing $19-$99/mo), Bold Quote ($39.99/mo), Wholesale Order Form & ReOrder ($29-$149/mo), B2B Edition apps.

3PL / WMS integration ($3,000-$15,000)
Warehouse management integration for accurate stock and order routing.

A B2B enterprise build I scoped in 2025 (HVAC parts distributor, 1,200 accounts, multi-region) totaled $87,000 over 6 months. Replaced a 12-year-old Magento 1 build that cost $9,000/mo to operate. New Shopify Plus build operating cost: $3,800/mo. Annual saving: $62,000 plus 18% improved B2B order conversion.

For enterprise-cost context see custom website cost 2026.

1. Don't jump to Plus until you have 30+ wholesale accounts.
Plus is $2,300/mo. Standard Shopify + wholesale apps ($118-$699/mo) handles under 30 accounts. Save $19K-$26K/year until you outgrow.

2. Use Plus native B2B over wholesale apps if you're on Plus.
Native B2B is included. Don't pay $100-$300/mo for wholesale apps that duplicate native features.

3. Defer EDI until you have 3+ retailer contracts.
$5,000-$15,000 setup + $400-$1,500/mo. Only worth it past $200K/year in EDI-required revenue.

4. Use Shopify's native ERP connectors instead of custom integration.
Shopify has native integrations with QuickBooks, Xero, NetSuite, Brightpearl. Saves $5,000-$15,000 vs custom API work.

5. Skip the sales rep portal for under 10 reps.
Reps can manage orders via Shopify admin with proper permissions. Custom rep portal ($5,000-$20,000) only justified at 10+ reps with complex commission/territory rules.

6. Use Klaviyo + Postscript instead of custom B2B email/SMS.
$200-$800/mo for B2B-tuned email + SMS. Replaces $5,000-$15,000 of custom comms work.

7. Use Plus native multi-location instead of multi-store.
For domestic multi-location (warehouses, regional offices), Plus native handles. Multi-store ($10,000-$30,000) only for international expansion.

8. Pre-build your customer onboarding workflow before launch.
Approval criteria, tax ID verification, resale certificate handling, welcome email. Pre-defining saves $3,000-$8,000 in workflow dev.

9. Use Slope or Resolve Pay for NET 30 / 60.
Outsource credit + payment terms to specialists ($100-$500/mo + 1-3% fee). Saves $5,000-$15,000 of custom credit workflow dev.

10. Don't custom-build multi-currency.
Shopify Markets (free with Plus) handles multi-currency natively. Don't pay for custom implementation.
