    In-house team

Conversion is a Shopify B2B development agency headquartered in San Francisco and a Shopify Plus Partner. We build wholesale and B2B ecommerce for manufacturers, distributors, and DTC brands adding a wholesale channel, across the US, Canada, UK, and Australia. That work draws on our Shopify Plus agency practice, wholesale migrations off legacy portals, and custom Shopify apps and Functions where requirements go beyond native features. ERP integration covers NetSuite, SAP, Dynamics, and Acumatica.

The wholesale buyer who approves POs at work shops on Shopify at home. They expect search that works, live inventory, their pricing without asking, and checkout with terms, and most still get a fax-era portal or an email thread with a rep. Native B2B on Shopify Plus makes that buildable without a seven-figure enterprise platform, and it's what our Shopify Plus development engineers build every week. Our Shopify Plus pricing guide covers the plan itself, and brands running retail and wholesale from one store can pair this with our Shopify development agency for the DTC storefront.

Why B2B ecommerce stalls

The wholesale channel is stuck in 2009

The same three bottlenecks show up in almost every wholesale operation we audit.

  • Reps as human order forms

    Your best salespeople spend their days re-keying emailed spreadsheets into the ERP. Every order costs rep time, every typo costs a support ticket, and reorders, the easiest revenue you have, wait in an inbox.

  • Wholesale apps that fight the platform

    Duct-taped wholesale apps and duplicate 'wholesale stores' create catalog drift, broken discounts, and checkout hacks that fail on updates. Native Plus B2B replaces the whole stack with platform-supported primitives.

  • Pricing chaos

    Contract pricing living in the ERP, spreadsheets, and reps' heads, with no single source of truth. Customer-specific price lists synced from the ERP mean the buyer sees the right price every time, without asking.

Shopify B2B development services

The full wholesale stack, built native

Everything a modern B2B operation needs on Shopify Plus, from company accounts to ERP sync to the quote-to-order pipeline.

  • Company Accounts & Buyer Roles

    Company records with multiple buyers, roles, and permissions; multiple shipping locations per company; and self-serve account management. The org chart of your customer, modeled in the platform.

    • Multi-buyer companies
    • Roles + permissions
    • Multiple ship-to locations
    • Self-serve account portal

  • Price Lists & Contract Pricing

    Customer-specific catalogs and price lists, quantity minimums, volume breaks, and percentage-off structures, synced from your ERP so contract pricing has one source of truth.

    • Customer-specific price lists
    • Volume + quantity breaks
    • Catalog visibility rules
    • ERP-synced contract pricing

  • Net Terms & B2B Payments

    Net 15/30/60 payment terms, vaulted cards, PO numbers at checkout, and draft-order invoicing, with credit limits enforced from ERP data via Shopify Functions.

    • Net terms checkout
    • Vaulted payment methods
    • PO number capture
    • Credit limit enforcement

  • Quote-to-Order Workflows

    Draft-order quoting, rep-assisted carts, quote approval flows, and reorder-in-one-click from order history. The negotiation stays human; the order entry doesn't.

    • Draft order quoting
    • Rep-assisted carts
    • Approval workflows
    • One-click reorders

  • ERP & Systems Integration

    NetSuite, SAP Business One, Microsoft Dynamics, Acumatica, QuickBooks. Pricing, credit, inventory, and order sync with monitored custom middleware where native connectors fall short.

    • NetSuite + SAP + Dynamics
    • Real-time inventory sync
    • Order + invoice flow
    • Monitored custom middleware

  • DTC + B2B Single-Instance Architecture

    Retail and wholesale from one Plus store: one catalog, one inventory pool, one reporting layer. Logged-in company buyers see their world; retail customers see yours.

    • Single-instance architecture
    • Shared catalog + inventory
    • Channel-specific theming
    • Unified reporting

    We show you which parts of the current wholesale stack company accounts, price lists, and net-terms checkout take over.

    Whether DTC and B2B should run from a single Plus instance or a separate wholesale expansion store. We'll tell you which fits on the first call.

  4. A fixed price on the build

    Account & pricing architecture

    Company records, buyer roles, price lists, and catalog visibility modeled, then validated against your messiest real customers before any build.

  3. Step 03

    Build & integrate

    B2B storefront, net-terms checkout, quote workflows, and ERP sync built and tested with staged data. Your reps beta-test with real accounts before launch.

Why Conversion

A B2B specialist, not an app installer

  • Native Plus B2B, in production

    Company accounts, price lists, net terms, and Functions-based credit logic, shipped and running. Ask other agencies to show you a live company-account checkout; we will.

  • ERP is a first-class citizen

    B2B without ERP sync is a demo. We integrate NetSuite, SAP, Dynamics, and Acumatica with monitored middleware, with pricing, credit, inventory, and orders flowing both ways.

  • Budget-honest scoping

    Most B2B builds land in the $50K to $80K range and we say so publicly. Fixed-scope quote within 48 hours, week-by-week roadmap on day one, no hourly black holes.

  • Revenue never pauses

    Parallel running, wave-based buyer onboarding, and controlled cutover. Your wholesale channel keeps trading through the entire migration.

  • Single-instance architecture

    DTC and B2B from one Plus store wherever possible: one catalog, one inventory pool, one reporting layer. Fewer moving parts, drastically lower operating cost.

  • A growth partner after launch

    Post-launch we run adoption campaigns, reorder automation, and CRO on the wholesale funnel, on a pay-on-results basis where it fits.

Frequently asked

Shopify B2B questions

What does a Shopify B2B development agency do?
A Shopify B2B development agency builds wholesale and B2B ecommerce experiences on Shopify Plus using the platform's native B2B features: company accounts with multiple buyers and locations, customer-specific catalogs and price lists, quantity rules and volume pricing, net-terms payment (net 15/30/60), quote-to-order workflows, and ERP integration. The goal is letting wholesale buyers self-serve, with their own pricing and terms, instead of emailing a sales rep a spreadsheet.
How much does a B2B Shopify Plus build cost?
Most of our B2B Plus builds land in the $50K to $80K range: company account architecture, price lists, net-terms checkout, quote workflows, and ERP hookup. A combined DTC + B2B build from scratch runs $80K to $150K. A focused wholesale migration from a legacy portal or a wholesale app to native Plus B2B typically runs $40K to $60K. We deliver a fixed-scope quote within 48 hours of a 30-minute discovery call.
Can Shopify handle B2B and wholesale?
Yes. Since Shopify rebuilt B2B natively into Shopify Plus, it handles serious wholesale operations: company accounts with buyer roles and multiple shipping locations, customer-specific catalogs and price lists, quantity minimums and volume breaks, net payment terms, vaulted cards, and draft-order quoting. For requirements beyond native features, such as configurators, contract pricing engines, and punch-out catalogs, we extend with Shopify Functions and custom apps.
Can I run DTC and B2B from the same Shopify store?
Yes, and it's usually the right architecture. Shopify Plus runs both from a single instance: retail buyers see the DTC storefront and prices, while logged-in company buyers see their catalog, their price list, and their payment terms. One product catalog, one inventory pool, one reporting layer, and no duplicate-store drift. A separate wholesale expansion store still makes sense in some cases (radically different branding or catalog), and we'll tell you which fits on the first call.
Do you migrate wholesale operations from legacy B2B portals to Shopify?
Yes. Replacing legacy B2B portals, the old wholesale channel app, or spreadsheet-and-email ordering is our most common B2B engagement. We migrate company records, buyer accounts, contract pricing, and open order history; rebuild pricing rules as native price lists; and run both systems in parallel through a controlled cutover so wholesale revenue never pauses. A typical wholesale migration on a ~$50K budget runs 8 to 12 weeks.
How does ERP integration work for B2B Shopify stores?
B2B lives and dies on data sync. We integrate NetSuite, SAP Business One, Microsoft Dynamics, Acumatica, and QuickBooks, syncing customer-specific pricing, credit limits and terms, real-time inventory across warehouses, and order flow back to the ERP for fulfillment and invoicing. Where native connectors fall short we build custom middleware in TypeScript with full monitoring, so a failed sync pages an engineer instead of silently dropping orders.
What's the best Shopify agency for a B2B build with a budget under $80K?
Look for a Shopify Plus Partner that has shipped native B2B (company accounts, price lists, net terms) in production, rather than a theme shop that installs a wholesale app. Under $80K you should get: discovery with a fixed-scope quote, company account and pricing architecture, net-terms checkout, quote-to-order workflows, ERP integration, and a tested cutover plan. That's the range most Conversion B2B builds land in, with a week-by-week roadmap from day one.
How long does a Shopify B2B build take?
A focused B2B implementation on an existing Plus store runs 6 to 10 weeks. A combined DTC + B2B build from scratch runs 12 to 16 weeks. Wholesale migrations from legacy portals run 8 to 12 weeks including the parallel-running period. ERP complexity is the biggest variable, so we scope it precisely during discovery and the timeline holds.
