To go-live
The hidden cost of running multiple ecommerce platforms.
You're probably managing 2–4 separate systems: a B2C Shopify store, a custom B2B wholesale portal, Amazon/marketplace listings, and parallel inventory and customer databases. The result is a daily operations nightmare that scales linearly with growth.
3–5 sales channels
DTC, wholesale, marketplace, direct, partner — each on its own platform with its own login, dashboard, and integration tax.
Fragmented data
Different customer DBs, inventory systems, pricing rules. Nobody trusts the numbers because every system gives a different answer.
3–4 weeks per launch
Every new product synced manually across catalogs, channels, and vendors. By the time you launch, the trend has moved on.
Customers see chaos
Different prices, availability, and offers across channels — brand damage, support tickets, and lost trust at scale.
US ecommerce 2024 — what the data says
"We were running our B2B portal separately from Shopify. It took 3 weeks to launch a new product because we had to sync it across two systems, two inventories, two customer databases. It was chaos."
One platform. B2B + B2C. Unified commerce that actually works.
What if you could consolidate every channel on a single Shopify Plus instance? Here's what changes — and what it's worth in dollars and weeks.
- One product catalog — launch in 2 days, not 3 weeks.
- One inventory system — real-time stock across all channels, zero overselling.
- One customer database — know who's buying on every channel.
- One pricing engine — volume discounts, tiered pricing, channel-specific rules in one place.
- One operations team — 1 person managing unified system vs. 3 managing separate platforms.

The Shopify Plus unified commerce framework: 4 phases, 6 months.
A repeatable migration we've shipped for distributors, retailers, and manufacturers across the US. Built around your operations, not against them. Zero downtime.
Assess & design
Audit current platforms. Map data flows for inventory, pricing, and customers. Decide what stays custom, what migrates to Shopify, what goes away. Output: unified architecture and phased migration plan.
Migrate to Shopify Plus
Stand up Shopify Plus with native B2B (price lists, NET terms, company accounts). Migrate the master catalog, customer base, and pricing rules. Wire ERP/SAP for real-time inventory. Old systems run in parallel — zero disruption.
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. Lock in $80–150K/yr in operational savings.
Optimize & scale
Layer on dynamic pricing, personalization, and fraud protection. Train your team. Hand over the playbook. Plan the next channel — international, new marketplaces, new B2B segments.
Key principles
Why Shopify Plus B2B + B2C pays for itself in weeks.
Most companies pay back the investment in 1–2 months from operational savings alone. Revenue uplift is the upside.

Brands building unified commerce on Shopify Plus.
"We were running 3 separate systems. The manual syncing was killing us. After consolidating to Shopify Plus, we cut our operations team from 3 people to 1 and launched products 3× faster. Best decision we made."
"We knew we needed to consolidate, but didn't know how much we were losing to system fragmentation. Mejix quantified it: $100K/year in operations costs plus $3M in missed revenue. ROI was obvious."
"The biggest win was understanding our customer across channels. We found 50 high-volume DTC customers who could buy wholesale. Converted them to wholesale tiers. That alone made the project profitable."
