Unified Commerce B2B Software: Capabilities and Shopify Advantage

You already know the headaches of managing multiple commerce systems: skipped syncs, messy catalogs, and the dreaded surprise stockout. What hurts more is the chain reaction these headaches trigger—sales stalls to fix quotes, buyers quietly lose confidence, and momentum slips away. 

That’s why choosing a truly unified commerce B2B software matters. When every product, order, and customer record lives in one system instead of being stitched together across platforms, errors drop and buyer trust grows.

The payoff shows up in measurable ways: higher average order values, greater buyer value, and a lower total cost of ownership compared to managing separate POS and ecommerce stacks.

Ahead, you’ll get a breakdown of how unified commerce works for B2B, the core capabilities to look for when choosing the right stack for your organization, and how brands are using it to simplify operations. 

Why unified commerce beats omnichannel for B2B

Omnichannel commerce solved the front-end problem for retailers. It allows buyers to navigate across touchpoints, but left the back end stuck in the past, tied together with middleware and manual reconciliations. 

When product data, contract pricing, and order histories live in separate systems, even the best B2B self-service portal can’t guarantee accurate stock, delivery dates or account-level discounts.

Unified commerce takes the next step. Instead of integrating separate systems, it runs every buying motion (web, marketplace, field sales, or POS) against a single data model on one platform. There are fewer integration points to break, clearer analytics, and a consistent experience that buyers trust.

The new baseline for B2B buyer expectations

The pandemic permanently changed how enterprises buy. Today, channel fluidity is non-negotiable. McKinsey’s 2024 B2B Pulse survey found that one-third of buyers still want face-to-face time, one-third prefer remote, and one-third opt for digital self-service at every stage of the journey.

Digital self-serve is especially on the rise. Forrester predicts that more than 50% of B2B deals worth $1 million or more will close through digital self-serve portals by the end of 2025, not through a salesperson. These buyers are expecting more personalized experiences as well, which include real-time inventory, tailored recommendations, contract pricing, and accurate delivery ETAs. 

These expectations highlight why back-end unity matters. Buyers don’t care how many systems you run—they care that the negotiated price is accurate in their portal, and that stock is truly available when they need it. Unified commerce delivers on those promises by design, especially when POS and ecommerce run on the same platform. 

Impact on AOV, buyer value, and service costs

A unified ecommerce strategy doesn’t just simplify architecture—it also shows up in your bottom line. When every department works from the same customer data view and context, teams gain efficiency and buyers get consistency. The results are measurable:

• Higher average order value (AOV): Brands running on Shopify’s unified data model see an average 8.9% lift in gross merchandise value (GMV). 
• Stronger buyer value: B2B merchants on Shopify record up to a 53% increase in GMV per buyer within the first year, a direct result of consistent pricing, real-time inventory, and self-serve reordering.
• Lower operating costs: Independent research found that Shopify’s total cost of ownership (TCO) is up to 36% better than our competitors. 

Core pillars of unified commerce architecture

The foundation of unified commerce starts with a single data model, APIs, and embedded payments that unify the back end.

Unified data model and single customer view

Legacy B2B platforms scatter data across enterprise resource planning (ERP), product information management (PIM), and other tools, creating silos that don’t talk to each other. 

Unified commerce technology solves this by consolidating all products, price lists, inventory counts, and order routes into a single data model. Each record has a single ID, so every channel—your ecommerce store, sales rep tablet, and EDI feed—reads and writes to the same source of truth. 

This “single brain” approach powers a single customer view (SCV). For B2B, that means each company record stores:

• All associated buyers and approval roles
• Contract-specific pricing and payment terms
• Complete order, invoice, and service history

Whenever the buyer reorders or changes a credit term, the unified customer profile updates instantly. Sales reps, finance, and self-serve portals all get the same live information. 

Real-time API orchestration layer

A unified commerce architecture lets teams query and update every touchpoint instantly. With Shopify’s event-driven GraphQL and REST APIs, plus webhooks and EventBridge streams, you can move inventory, edit price lists, or update payment terms in real time. 

Every API call hits the same standardized data model, so EDI messages or headless storefronts update a single record rather than juggling point-to-point integrations. 

Plus, API-first design means Hydrogen, a React storefront, or a sales rep tablet can consume the same live endpoints, meeting rising buyer demand for real-time visibility instead of overnight syncs.

💡Did you know? A headless build with Hydrogen allows for smoother and more flexible integrations with the essential systems that power B2B unified commerce operations, such as ERPs (for inventory and pricing), CRMs (for customer data), and PIMs (for product information).

Embedded payments and tax compliance at scale

When payments and taxes run on the same platform, you save on tech spend and keep financial audits simple. 

Shopify builds payments and taxes into the core platform, so every B2B order settles on the same ledger and inherits the right tax rules automatically. Shopify Payments can handle enterprise volume—merchants processed $41.1 billion in gross payment volume in Q2 2024, representing 61% of all GMV on Shopify. 

The same unification extends to tax. Shopify Tax calculates US sales taxes and issues compliant VAT invoices across all 26 EU countries, plus the UK. As of mid-2025, a partnership with Sovos lets eligible US-based businesses auto-file and remit returns directly from the Shopify admin.

Core capabilities of a unified commerce B2B software

Unified commerce isn’t just about cleaner back-end systems. It’s about the buyer experience your systems unlock. Here are the capabilities that matter most:

Role-based pricing and approvals

For buyers, trust starts with seeing the right terms every time they log in. A unified commerce platform makes that possible by attaching multiple contracts to a single company record and assigning each location its own price list or discounts, all from one managed login. When an approved buyer signs in, the storefront automatically pulls the right price and approval workflows. 

This approach consistently improves the buyer experience and has helped brands like AMR Hair & Beauty triple sales and increase B2B average order value by 77%.

“Right now, we have two login options, one for public consumers and one for B2B customers,” says Ammar Issa, founder of AMR Hair & Beauty. “We have 10 different pricing tiers for B2B customers, and Shopify automatically shows them the right one based on their customer status.”

Real-time inventory and order logs

Buyers lose confidence when promised items are unavailable. A unified commerce platform tracks stock at the location level and updates quantities the moment a pick, receipt, or transfer happens, so buyers and sales reps always see live, accurate availability.

Each change also writes to a dedicated inventory API and order timeline, giving ops teams a searchable history of who moved what and when. 

Native ERP and CRM connectors

Buyers expect accurate pricing and account details every time—they won’t wait for systems to catch up. Native ERP and customer relationship management software (CRM) connectors ensure data flows between systems in real time, eliminating CSV uploads and brittle middleware that leaves numbers out of date.

Shopify’s Global ERP Program offers certified, one-click apps for NetSuite, Microsoft Dynamics 365 Business Central, Infor, Acumatica, and Brightpearl. These connectors write orders, inventory moves, and financial postings directly into the ERP’s ledger in real time. 

Self-service portals for reorders and quotes

B2B buyers want the same convenience they get as consumers—real-time stock, one-click reorders, and seamless quotes. According to a 2024 Forrester-commissioned survey, 73% of buyers want that digital experience, yet only 36% of companies deliver it. 

A unified commerce platform should make self-service simple. With Shopify B2B, buyers can duplicate their past orders in one click, or accept a rep-generated draft order as a quote and pay on their approved terms. 

Robust analytics and AI demand forecasting

Businesses that can see and forecast demand in real time make faster, smarter decisions for their buyers. A unified B2B ecommerce platform makes this possible by pulling live, omnichannel data into one place. With ShopifyQL Notebooks, merchants can query and visualize their unified sales, inventory, and customer data directly, tracking B2B KPIs like AOV and fill rate. 

For planning, AI demand-forecasting tools are non-negotiable. As of Q1 2025, 98% of companies report integrating AI into their supply chains to help with forecasting and inventory optimization. Together, live analytics and predictive forecasting can keep buyers supplied without burdening you with holding costs. 

Enterprise-grade security and compliance

Large buyers won’t commit unless they trust that their data is protected. Your platform must satisfy the same checklists your CFO and auditors use:

• PCI DSS Level 1 for card data
• SOC 2 Type II for cloud controls
• ISO 270001 for infosec governanc 

With the correct certifications in place, enterprise buyers can process payments and store customer data without additional compliance tools. 

Shopify’s unified commerce approach for B2B

Here’s how Shopify brings those core capabilities to life with built-in B2B tools.

Company profiles, price lists, and self-serve checkout

Shopify’s B2B model starts with company profiles, which are individual records that store multiple contacts, locations, payment terms, and tax IDs for each buyer account. 

You attach price lists (catalogs) to those profiles, so every buyer sees the right currency, volume tier, and product mix when they log in. 

At checkout, contract prices apply automatically, approved customers can pay on net terms, and orders post back to the same company profile for finance and ops to reconcile in real time.

One unified back office

Running both ecommerce and POS on the same platform means one product catalog, one inventory count, and one order ledger. Shopify’s unified stack provides exactly this, so whether a sale happens in a showroom, online store, or wholesale portal, it all draws from the same data model. 

With a single ledger, finance and ops gain consistency across every channel—from tax treatment to partial pickups—reducing manual work and costly errors. Independent research shows retailers that merge Shopify POS with their online storefront cut total cost of ownership by 22% on average and implement 20% faster than those juggling separate systems.

Extensibility via Functions, Flow, and headless APIs

Shopify also lets you inject custom logic to tailor B2B experiences at enterprise scale:

• Functions run inside Shopify’s checkout and cart to add logic like volume-tier discounts or custom payment rules.
• Flow automates B2B chores, like auto-assigning new company locations to the right price list or emailing credit limit alerts, through drag-and-drop workflows.
• Headless APIs (Storefront, Admin, B2B) feed Hydrogen or any React/Vue front end, so you can launch portals, rep apps, or kiosks without duplicating data.

Comparing leading unified commerce B2B platforms

Many platforms integrate separate products through connectors. Shopify unifies channels and data on one platform. That difference shows up in conversion, cost, and speed to launch.

Shopify vs. Salesforce

With lower license fees, faster deployments, and a proven conversion edge, Shopify frees budget and time you can redeploy into wholesale portal features, rather than propping up multi-cloud infrastructure. 

Here are the numbers:

• Checkout performance: An independent consulting firm found Shopify Checkout converts 36% better than Salesforce Commerce Cloud’s.
• Lower total cost of ownership: Shopify’s own TCO calculator, built on that same research, shows the platform runs on average 35% cheaper over five years once you add licenses, development hours, and maintenance. 
• Speed to launch: Brands migrating from Salesforce routinely go live on Shopify in under six months. Mustang Survival completed their switch in just 92 days, then recorded a 172% conversion jump.

Unified vs. integrated: Shopify has run POS and ecommerce on one platform from day one, so data flows through a single source of truth. Salesforce acquired its commerce solutions, resulting in a platform that has mixed architectures.

Shopify vs. Adobe Commerce

If launch speed, low-code extensibility, and proven global scale are your priorities, the data points to Shopify over Adobe Commerce.

What the data shows:

• Faster time to market: Thanks to a more user-friendly admin and prebuilt ERP connectors, brands launch storefronts 40% faster on Shopify.
• Lower total cost of ownership: Independent research commissioned by Shopify shows its five-year TCO is 29% better than Adobe’s, while Adobe projects rack up 42% higher implementation costs, 42% higher platform fees, and 24% higher operating costs.
• Better site performance: Shopify Checkout averages 5% higher conversion and stores load 2x faster than Adobe sites, backed by ~100-millisecond Storefront API responses and 99.9% uptime.

Unified vs. integrated: Shopify unifies POS, B2B, and ecommerce on one platform. Adobe Commerce depends on custom and third-party integrations, adding cos and complexity.

Shopify vs. BigCommerce

A deeper app ecosystem and higher conversion rates make Shopify a pragmatic choice for B2B unified commerce. 

The results:

• More cost-effective in the long run: Independent research shows Shopify’s five-year TCO is 31% better on average; BigCommerce shows 88% higher implementation costs, 32% higher platform fees, and 21% higher operating/support costs.
• Stronger checkout conversions: Shopify Checkout converts 12% better on average than BigCommerce. Fitness brand Crossrope saw a 24% conversion lift and 90% revenue increase after migrating from BigCommerce to Shopify.
• Better B2B tools: With 2,380 partners and more than 8,000 apps versus BigCommerce’s 1,237 partners and ~1,200 apps, Shopify offers far more plug-and-play options. Its built-in B2B suite plus Shopify POS reduc reliance on third-party add-ons that can fragment data.

Unified vs. integrated: Shopify runs every channel from one source of truth. BigCommerce relies on external apps that can disrupt consistency.

Case studies: Unified commerce lessons from high-growth brands

Leading brands are cutting costs and complexity with Shopify’s unified approach.

Simon Pearce

Heritage glassmaker Simon Pearce replaced three disconnected systems (a separate ecommerce site, a legacy POS, and a stand-alone wholesale portal) with a single Shopify back office. 

The move ended Q4 POS outages, shifted inventory visibility from once daily to real time, and cut custom engraving approvals from multi-day email chains to instant digital proofs that generate work orders on the spot. 

Tony’s Chocolonely

Facing mounting maintenance costs and peak season crashes on a bespoke stack, Tony’s Chocolonely migrated to Shopify and merged three sites into one unified storefront. 

Unifying every channel on a scalable core freed Tony’s team from patchwork fixes and let them focus on bigger activations. It also allowed them to create unique buying experiences. 

For example, automated “pay by invoice” and volume discount tools streamline large corporate orders. The brand also integrated a custom “Wrapper Creator” personalization app that plugs straight into Shopify’s APIs for seamless gifting experiences.

The switch ultimately resulted in: 

• 2.5 times faster site speed
• Double-digit revenue growth across four key markets, including 70% in the US

The Conran Shop

When Digital Director Richard Voyce tallied the hours (and pounds) spent keeping a heavily customized Magento site operational, he realized the brand was being held back by legacy tech. 

The team adopted a mindset of “reducing complexity, reducing cost, reducing effort,” and migrated to Shopify’s unified commerce solution. They started with a phased rollout with zero downtime. 

A new Kuwait site went live first, giving the team confidence to migrate their flagship UK storefront in February 2024. Customers quickly noticed the cleaner navigation and faster checkout.

The Conran Shop rolled out Shopify POS across their physical stores and launched a wholesale-only B2B site in September 2024, all drawing on the same product and inventory data. Staff now capture customer details in-store and trigger Klaviyo flows automatically to deliver a showroom experience that mirrors online ease.

With Shopify, the retailer saw:

• 50% reduction in TCO
• 54% increase in online conversion rate
• 23% increase in email marketing revenue
