Shopify B2B Development Agency

Wholesale that sells itself

Native B2B on Shopify Plus — company accounts, customer-specific price lists, net terms, and quote-to-order workflows. Your wholesale buyers self-serve; your reps stop keying orders from spreadsheets.

  • Native Plus B2B — not a wholesale app bolt-on
  • DTC + B2B from a single Shopify Plus instance
  • ERP-integrated: NetSuite, SAP, Dynamics, Acumatica
  • Most B2B builds land in the $50K–$80K range

In-house team

Conversion is a Shopify B2B development agency headquartered in San Francisco and a Shopify Plus Partner since 2019. We build wholesale and B2B ecommerce for manufacturers, distributors, and DTC brands adding a wholesale channel — across the US, Canada, UK, and Australia.

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 — not a fax-era portal or an email thread with a rep. Native B2B on Shopify Plus finally makes that buildable without a seven-figure enterprise platform, and it's what we build every week.

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.

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

Our B2B delivery process

From spreadsheet orders to self-serve in 8–12 weeks

Conversion's four-stage growth process visualized in brand blue and green
01

Wholesale audit & scoping

We map your current order flow, pricing structures, terms, and ERP surface. You get a fixed-scope quote and week-by-week roadmap within 48 hours of discovery.

02

Account & pricing architecture

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

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.

04

Parallel run & cutover

New and old channels run in parallel while buyers onboard in waves. Wholesale revenue never pauses. Post-launch, adoption and reorder-rate reporting shows the channel compounding.

B2B case studies

Wholesale moved online. Reps freed up.

Shopify Plus — Industrial supplies

+61%

B2B revenue YoY

Legacy portal replaced with native Plus company accounts

“Our reps used to key orders into a 2009-era portal. Now wholesale buyers self-serve with their own price lists and net terms. B2B revenue is up 61% year over year.”

Shopify Plus — Food & beverage

83%

orders self-served

From email-and-spreadsheet ordering to one-click reorders

“Within a quarter, four out of five wholesale orders came through the store without a rep touching them. Our sales team finally sells instead of doing data entry.”

Shopify Plus — Apparel

DTC + B2B

Wholesale channel launched beside DTC without a second store

“We assumed we needed a separate wholesale site. Conversion ran both from one Plus instance — one catalog, one inventory pool. Operationally it's night and day.”

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, not listed on a capabilities slide. 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 — pricing, credit, inventory, and orders flowing both ways.

Budget-honest scoping

Most B2B builds land in the $50K–$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–$80K range: company account architecture, price lists, net-terms checkout, quote workflows, and ERP hookup. A combined DTC + B2B build from scratch runs $80K–$150K. A focused wholesale migration from a legacy portal or a wholesale app to native Plus B2B typically runs $40K–$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 — configurators, contract pricing engines, 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 — 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 8–12 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 — not 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 precisely 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 6–10 weeks. A combined DTC + B2B build from scratch runs 12–16 weeks. Wholesale migrations from legacy portals run 8–12 weeks including the parallel-running period. ERP complexity is the biggest variable — we scope it precisely during discovery so the timeline holds.
