02 / 08 · The Multiplication Problem

## More channels = more platforms = more chaos.

You started with B2C. Then B2B. Then marketplaces. Now you're running 3–5 systems that don't talk to each other.

3–5 sales channels

DTC, wholesale, marketplace, direct, partner — each on its own platform.

Fragmented data

Different customer DBs, inventory systems, pricing rules. Nobody trusts the numbers.

3–4 weeks per launch

Every new product synced manually across catalogs, channels, and vendors.

Customers see chaos

Different prices, availability, and offers across channels — brand damage.

US ecommerce 2024

70% of B2B transactions are now digital (vs. 40% in 2019) 

$60–150K annual operational labor wasted syncing platforms 

58% of ecommerce leaders rank channel integration as #1 challenge 

60% of customers expect unified pricing across channels

## Faster launches = faster growth.

Mid-sized retailer · $30M revenue · adding B2B wholesale to an existing Shopify B2C store.

04 / 08 · Why Partial Solutions Fail

## B2B Edition, custom portals, point stacks — all three break.

Each looks like a fix on day one. Each becomes the next problem to solve by month six.

### Shopify B2B Edition alone

Technically 'part of Shopify' but runs separately from your B2C store. Two admin interfaces, two customer experiences, manual inventory sync — fragile at best.

### Custom B2B portal

Built for one thing — wholesale. Doesn't extend to marketplaces or partner channels. Engineering debt grows every quarter; security patches never end.

### Best-of-breed point solutions

Shopify + Salsify + Zapier + custom middleware. 30–40% of project budget disappears into 'getting systems to talk.' Every API update breaks something.

Best-of-breed monthly stack

-   Shopify (B2C) $50–150K 
-   Salsify (B2B) $50–80K 
-   Integration platform $20–50K 
-   Custom dev / middleware $50–100K 

Total $170–480K / mo 

Shopify Plus unified

$100–200K / mo

One platform. One contract. One source of truth for inventory, pricing, and customer data. Native B2B + B2C — designed in, not bolted on.

05 / 08 · The Unified Commerce Blueprint

## One platform. Every channel. Six months.

Four phases. Built around your operations, not against them.

01 Weeks 1–3 

### Assess & design

Audit current platforms. Map data flows for inventory, pricing, and customers. Design the unified Shopify Plus architecture and phased migration plan.

02 Weeks 4–12 

### Migrate to Shopify Plus

Stand up Shopify Plus with native B2B. Migrate the master catalog, customer base, and pricing rules. Connect to ERP for real-time inventory. Run old systems in parallel.

03 Weeks 13–18 

### Connect channels

Hook up Amazon, eBay, Alibaba, and partner channels. Wire analytics into BigQuery + Tableau. Go live on Shopify Plus and decommission the legacy stack.

04 Weeks 19–24+ 

### Optimize & scale

Lock in $100K/yr in operational savings. Layer on dynamic pricing and personalization. Train your team, hand over the playbook, plan the next channel.

Key principles

One source of truth — inventory, pricing, customer data. 

Multi-channel ready — B2C, B2B, marketplace, partner, all on one stack. 

Scales from $3M to $300M+ revenue on the same architecture. 

Your team owns it — playbook documented, knowledge transferred.

### Why Shopify Plus instead of Magento, BigCommerce, or a custom build?

Shopify Plus is the only enterprise platform that ships native B2B (price lists, NET terms, company accounts, quote-to-cart) and B2C on a single storefront — no separate codebase, no duplicate catalog, no integration tax. Magento needs custom B2B modules and a 9–12 month rebuild; BigCommerce lacks native quote workflows; a custom build is a $2M+ multi-year commitment. Shopify Plus launches in 90 days with 99.99% uptime guaranteed.

### Can we really run B2B and B2C on the same storefront without compromising either?

### We have 50,000+ SKUs, 200+ price lists, and a complex tax setup. Will Shopify Plus handle it?

### How do you migrate without losing SEO traffic or breaking customer accounts?

### What about ERP, CRM, and 3PL integrations? We have NetSuite, Salesforce, and ShipStation.

### How do you protect us from credit card fraud and chargebacks at scale?

### What does a 90-day Shopify Plus launch actually look like?

### What happens after launch — do you stay involved?
